Breaking Up with Heather (Futa Version)

Heather knew she was sexy. She knew it with every fiber of her being. Men wanted her. Some women wanted her. She was skinny and well-endowed for her figure. What would've been moderate breasts on a buxom woman seemed full and beautiful on her, displayed proudly in a push-up bra that pressed them together in a line of ample cleavage. She served them up for view in a low cut tank top, sleeveless to reveal her pale smooth arms. Her butt was thick and muscular, and her hips swung when she walked. She sometimes wore jean shorts so tight that they seemed painted on. Otherwise she wore skirts that rose and fell with every step, giving anyone who stared a brief glimpse of inner thigh. If she raised one leg on a step, she revealed the prize--the bulge of her shaved pussy mound, which filled her tight white panties with obvious camel toe.

She had long blond hair and naturally pale skin. She didn't try to tan, she shaved fastidiously all over, and she wore little makeup other than red lipstick. She felt she barely needed to improve herself because she was so excellent--she believed this with a conviction so strong that it bordered on zealotry and brooked no argument. She'd heard the gossip about other men, deeply jealous of her "plain" skinny boyfriend, Ben. They worked out. They were fit and strong. What did he have that they didn't?

A fat eight inch cock, for starters.

It was true that the size of a penis hardly mattered. Eight inches or six, it felt surprisingly similar when sliding in her pussy, but she was obsessed with cocks and balls. She loved the shape of a penis, the flared head, and the foreskin pulling back as she stroked down. She loved the heft and softness of testicles in her palm, then against her face and then kissed by her lips. Her clit hammered with sympathetic arousal whenever she shook her fat ass and saw Ben's monster erection, swelling stiffer and fatter until it rose and bobbed against his belly button.

She dreamed about dick. She sucked it to the hilt and swallowed it with her asshole and brought it into herself in every way she could, deeper and harder. Sometimes, she would spoon with Ben late and night, reaching around his hard thin body, down between his thighs, to play with his penis. Slowly but surely, it would harden, and she would admire its heft and heat in her tiny palm while stroking him, until she was too wet and he was too horny and they'd have to fuck right there.

It was the idea that really turned her on, that all that cock would get stiff as steel for her.

Not that the experience was only about sex. Ben was so close to her, so dear, and she'd found herself spending less and less time with her friends. If she had something to think about--or an anxiety to work out--he was there.

Though she didn't say it often, she loved him, and didn't he love her?

And wasn't she still the sexiest girl on campus?

Yes, yes. So on their special day, after she'd spent so much time cleaning up and dressing up for a little butt play, why the fuck was Benjamin here telling her that he was going to spend time with his friends instead? They were both seated on the opposite sides of a dining table in her rented house, and though the distance between them was four feet of lacquered wood, it felt like miles.

"They've been talking a lot about this," Ben said. His gaze was fixed to one side of Heather's face. He could hardly bear to meet her eyes right now, yet this shit was still coming out of his mouth. "I spend all my time here almost every weekend."

"You come over every other weekend," Heather said sharply, "you spend the rest with your friends." Her arms were crossed on the table, and she was squeezing her left elbow with her right hand reflexively, trying to channel her anger like her arm was a stress ball. It wasn't working very well. Her elbow hurt a little.

"Okay," he said, "but they said--"

"Who cares what they said?" Her fingernails dug into her elbow slightly. She tried to relax.

"See, that's part of the problem," Ben said, "they said you don't think about their needs..."

"Their needs?" Heather was aghast. They'd taken pictures of her in bathing suits and posted them to Facebook. They were known to repeatedly tell Ben how he'd scored out of his league. Their only pastimes were to jerk off and be jealous, if anything. Their fucking needs? Ben already divided his time almost half between them and her. "What needs could they possibly have?"

"We used to hit the town every weekend," Ben said, "me and the boys."

"Now you have a girlfriend," Heather said fiercely.

"I don't know," Ben said.

That lit an anxious fire in Heather's belly. Her hand clenched again. She left little imprints of fingernails in her skin. "What does that mean?"

"They've been talking about you."

"They always talk about me."

"No, I mean, they've been telling me how it is. You know?"

Heather closed her eyes. The fire in her belly was getting hotter, fiercer. "Who cares what they said?"

"It matters--"

"It doesn't!" she shouted. She caught herself and tried to talk in a quieter voice, but she was still tensed up to the point that it almost hurt. "All that matters is how you feel about me."

He looked down at the table.

Heather felt a searing rage sweeping across her body in waves. His friends had poisoned this relationship, hadn't they? And they'd told him it was for his own good, she was sure of it, but it was really about undermining him, because they were pissed that he'd landed a girl of her caliber. Well fuck that, she wasn't going to let him go without words. "You still love me, don't you Ben?"

"That's not the problem--"

"Ben!"

Ben flinched, looked briefly conflicted and sighed at the table. "If the only thing that mattered was how I felt, yes, I love you."

"Great!" she shouted angrily, "No problems then!" She grabbed at her tank top and yanked down, letting one fat breast and erect nipple jut into the air. "You can grab one of these!" She pulled her top back up. "And then you can fuck me in the ass because you love me!"

Every word sounded like an awful accusation. She knew it and regretted it, but it was too late. He was already frowning. She crossed her arms again and tried to hold in the rage, but the pressure was building too rapidly. She was going to lose control.

"You don't have to be sarcastic," Ben said.

"Well what the hell is this?" she asked, feeling the anger redouble. She was going to explode. How dare he accuse her of being sarcastic--he was the asshole letting himself be pushed around by his friends.

"They've just been opening my eyes, okay?" he said, trying to be brave, trying to make his tone matter of fact so that she couldn't argue. "I love you, but you've got problems."

"Problems they told you about?" she said venomously. Her hand was clenching spastically at her elbow, but she didn't care if she drew blood. All she could feel was the intense fury at what was so obviously coming, at the words that Ben was about to speak because of his stupid fucking friends.

"They say you're really possessive," Ben said.

"Because I love you!" she shouted.

"You're doing it right now!" he whined.

"Because this is our day!" Her hand was clenching so hard at her elbow that her knuckles were white.

"Not anymore," he said impulsively, "I'm done. We're breaking up."

Heather felt every muscle in her body tense, her eyes shutting, the rage exploding out of her. Her little clit was hard. Her nipples were erect. She gritted her jaw and shuddered and her fingernails dug through her skin, breaking through without drawing blood, and without thinking, she raised her quivering left arm across her heaving breasts and finally found release, a single word, a single action.

"No!" she roared at the top of her lungs, and she grabbed a handful of flesh at her left elbow and ripped it open, violently peeling the skin off her arm in one swift pull, a wet sound like removing a soaked evening glove.

"Jesus Christ!" Ben shouted.

Heather opened her eyes and looked at the pale, empty skin in her right hand, impossibly thin and inside out. Her left arm shuddered, her fingers curved and twitching. This had been beneath her skin, a beast's arm covered in damp, black fur. On her new fingertips, scything onyx claws grew in satisfying bursts.

She didn't understand it, but she wasn't afraid, only surprised. Instinct guided her, channeled her fury. Ben, the goddamned wuss, had been misled by his stupid fucking friends, but she wouldn't let him go. Not now, with all her throbbing body and her strange new arm, would he be allowed to break up with her. Not when she knew, deep down, that she was about to look the way she felt.

Animal, furious and horny.

She stood up and dropped the empty skin on the table between them. "You're mine!" she shouted. The creature Heather wanted to be was boiling just beneath the surface, monstrous and powerful. With her brand new claws, she grabbed her right elbow and instantly cut through, then ripped away the skin on her right arm, revealing another stretch of wet black fur and another monstrous hand.

Ben was stupefied.

"Don't move!" Heather threw the skin on the floor and flexed her clawed fingers, feeling the power and strength of her monstrous arms.

Ben whimpered.

Heather looked down at her blushing breasts in a push up bra. "I dressed like this..." she muttered, then felt another pang of rage. She cupped her tits in her new hands and felt the heft of her ample breasts. Then she sank her claws into the cloth, cutting through shirt and bra. "I dressed up for you!" she shouted.

"I'm sorry!" Ben shouted back.

Heather ripped open the front of her tank top and bra. Her breasts burst outward as she bared her chest, arching her back. She already had over proportioned breasts. Now they were both swollen, ruddy, and capped with erect, inflamed nipples.

Ben was agape. He was staring at her naked chest.

She felt a twinge of hardcore arousal in her thick pussy. She grunted angrily and flinched. She wanted to be wanted, but she was so incredibly pissed.

"Heather?" Ben asked.

"I'm so horny!" Heather shouted back, "But you don't want me? Fuck you!"

"Please, don't do this."

"Do what, you little shit?" She ripped her shirt and bra off entirely and threw them on the ground, now naked from the waist up.

"This," Ben said, "this. Stop. Please, stop!"

"Stop?" Heather asked. She lifted her arms up, clawed and furry. "This is me, Ben. This is the real me." She petted her engorged tits with her bestial hands, stroking her sensitive, swollen nipples. Her breasts had never felt this aroused before.

"Please."

"I just didn't know it." She flinched again. There was a crackle of flesh shifting inside of her, and it felt glorious. "Not until..." She grunted, then shuddered with arousal. "...you made me angry enough."

"Heather, please!"

"Now you'll see..." Her jaw stopped for a moment and crackled. "You'll see the beast you woke up. The beast inside--" She cried out in pain and pleasure as her mouth bulged forward very slightly with a bony snap, giving the lightest impression of a maw on her human face. She bared her teeth at him and grimaced as they extended from her gums, knifing longer, more carnivorous. Then, as quickly as it started, she could close her mouth and fit her teeth together again, beautiful red lips twisting into a grimace. "The old me would've let you go."

"Let me go?"

Heather reached down, grabbed the hem of her skirt and began to tear it in two with ease. "Take off your pants!" she shouted.

Ben rushed to stand and strip off his pants.

Heather finished tearing away the skirt and looked down at her tight underwear and damp thighs. The cloth was soaked, half-clear. "Do you see this pussy?" She slapped her bulging mound lightly and gave it a quick rub. "I'm this wet, and you wouldn't fuck this? You wouldn't turn me around and ram my ass?" She slung her juice at him, hitting him in the face with a couple of droplets. "You're a worthless prick!"

Ben closed his eyes but didn't even move to wipe his face.

"Look at me!" Heather shouted.

He opened them.

"Strip!" Heather grabbed her sopping panties and sliced open the crotch with a claw, leaving a circle of elastic on her hips, draped soaked cloth, and her bare slick pussy. Showing off her vagina made her little clit hammer with arousal. She wanted to rub herself to orgasm, but not yet. Not by a long shot. "Show me your fucking cock!"

He kicked away his shoes and pants, still wearing socks. He hesitated only a moment before relenting, and he pulled down his boxers.

Her mouth began to salivate. He was partially stiff, swollen and heavy. That made her horny as hell. He was still turned on by her body, even when scared shitless. Fuck, that made her so goddamn horny, she shivered. She wanted to suck his cock until it was steel, and she hated him for still turning her on. But wasn't that what this was about? She was going to keep him, no matter the cost. Not even her humanity would stop her now.

"Fuck it." She took two steps forward, hips swinging, feeling her inner thighs dripping with lube. She stopped before Ben and looked up at him, grinning with animal teeth. With her left hand, she very gently reached beneath his heavy cock and cupped his balls. The warm, naked pads of her fingers scraped over his trimmed hair. With her right, she grabbed his thick penis and gave it two brief jerks, pulling back his foreskin to unveil his ruddy, almost purple cockhead. He hardened significantly in her hands.

"Heather." His voice shook. Lust or terror, she didn't care.

"This fucking turns you on," she whispered and pulled up his foreskin, to gently rub the underside of his cockhead through the skin. Then she slid it back and patted its stiffening mass against her groin. There were two tiny wet slaps of precum.

"Jesus Christ," he said.

She let go of his bobbing cock and grabbed his skinny hips. Then she lowered herself down against his body, squatting slowly, spreading her legs open. Her pussy felt so exposed, so naked. Her clit nearly hurt, it was so stiff! His cock slid up between her throbbing aroused tits. God, she thought, my nipples feel so fucking good. She took a moment to turn back and forth, gently pressing her fat erect tits against his burning hot cock.

Ben didn't even say anything. He groaned.

Heather gasped. Her nipples had never felt this erotic before. Her breasts felt so heavy, so intense. She felt if she touched herself, she would cum too early. Even sucking cock, something that already turned her on, felt like it might be enough to make her squirt.

Her claws clenched against his skin, and another scowl crossed her face. He froze in her grasp. Fuck Ben, she thought, and fuck his friends. Fuck this wuss fucking boyfriend who didn't want her anymore, didn't want the human Heather. Now there would be no more bullshit. The inner Heather would have him. She was his monster, hatching from the girl he rejected, born of love, fury and sex, and he was hers to take.

If she wanted to suck cock one last time as a human girl, then fuck it.

She grabbed his erect dick at the base, angled it down, opened wide and jammed his thick penis in her mouth. The flavor of precum, of sex, brushed over her wet tongue. She bobbed her head a few times, pushing his foreskin back further and further with her lips. Then she changed angles and pressed the head of his penis to the roof of her mouth, keeping her beastly teeth away from his tender flesh. She wriggled and rubbed his cockhead against her palate, and she growled with anger and ecstasy.

He was frozen still, maybe afraid that she would bite his dick off.

He'd know better once she'd jammed his rod down her throat.

She tilted his cock and angled her head, then started feeding his thick member deeper and deeper. He was such a big man, and her mouth was full right to the back. She huffed with her nose, then smoothly swallowed deeper. No gagging. Slick and easy. She was talented at deepthroat, and the animal within her was hungry for cum.

"Oh fuck," he muttered. "Fuck, fuck."

There was a series of soft pops in Heather's back as her spine began to shift very slightly. She hung onto his hips with her claws and sank to her knees, gently touching her teeth near the base of his dick and forcing him down.

"Ah! Ah!"

She kept lowering her body until Ben had to squat to stay in her throat without running his dick against her fangs. She rested on her hands and knees, head tilted back as far as she could manage, face forward right into his crotch. She could feel his balls draped over her dainty chin. Her mouth was opened wide around his tremendous prick. He hunched over her beautiful face, her lipstick rubbing off at the base of his cock. Her face was flush with shame. Finally dominated, her kink. She was his woman to fuck in the face, up the ass. She closed her eyes and slid back, cock halfway out, until she could just breathe through her nose, and drank in the smell of sex.

He balanced himself by grabbing onto her shoulders.

She held her breath and pushed back in. Ben knew how to do this. Without a word, she waited for him to begin, even though he didn't deserve this treat--this final go round. Still, her anger made this all the more arousing. He would hump her body even as she burst open to unleash the rage monster within.

"Heather, do you want--?"

She opened her eyes and nodded very slightly.

He was so hard, a pork sword sheathed into her throat like a scabbard. He pulled back an inch, groaning as she tightened around him. He pushed forward an inch. When his balls slapped her chin, Heather's eyes rolled back in her head, and her pussy gushed. If anything, her mound felt thicker, fatter, hornier than ever before. Her pale skin was mottled and blushing. She wished she'd shoved a couple of vibrators in her ass and pussy first. Before she met Ben, she'd commonly masturbated to rough gangbang porn with a butt plug hidden under her panties, mimicking a fantasy where she flicked the bean in public.

Her asshole winked at the thought, empty and aching to be filled.

Ben humped her face again, slow and steady.

Heather's large, aroused breasts hung from her chest and jiggled lightly with his thrust. Heather could feel her nipples throb with the agony of pleasure scorned, becoming inhumanly sensitive. Somehow, her tits were becoming more engorged, her grand nipples getting broader and puffier. Ben pumped a little faster, and she could tell with certainty now, her breasts were growing larger quickly. Their ample mass began to press together naturally, expanding, filling with the raw pleasure of sex.

She didn't even need to look down to know they were huge and soft, but not sagging. They were firm but pliable, and if she turned her body up, she knew they would stand proud without a bra, erect nipples jutting. She had the urge to reach down and tug on them, to masturbate by breast alone, but she remained still to hold Ben's weight over her arms.

Ben pulled out further and paused, letting Heather breathe out the stale air and take a few deep breaths through her nose. She'd gotten her throat to relax enough. She held her breath, and he swiftly sank all eight inches back through her crimson lips.

Her rump began to tingle with arousal. Her ass was round and tight, still draped over with a flap of damp, half-clear panties. She was already anally aroused; she'd played with both holes together for too long. The association was deep, and she craved being fucked in her butt whenever her pussy was damp. But this sensation? This was new.

Her asshole throbbed with the same insane sensitivity as her nipples. It was the creature inside her, the real Heather. It was still growing, and another step in its rebirth was near. This feeling was her reward for indulging her dark side. Ben was picking up the pace, rubbing his entire cock in her mouth. His balls slapped against Heather's jaw, and she felt another pang of anger and lust.

She couldn't imagine that he hadn't wanted to do this, that he was willing to give this up to satisfy his friends. How many men had a girlfriend as kinky and animal as her? Why did she have to literally become that animal to keep this?

There was a sharp snap in her rump, and she could feel new growth sliding down over her pelvic bone, between her asscheeks and towards her asshole. Every thrust of Ben's massive cock was mirrored in her crackling extension.

Her breasts had paused in their growth, but her tremendous nipples were reaching a breaking point. There was pressure growing in them, a sense of impending, exploding orgasm like the moment before she'd squirt.

Something deep in her loins told her that she was about to find an animal release. Sexual instinct told her that she was about to cum milk from her breasts, and she welcomed it. She urged it on. She'd cum from her titties. She'd cum from everything that could squirt and squint and shudder. Cum breasts, she shouted in her head, cum hard!

There was a pressure in her ass. She arched her back without thinking, trying to bend over further to open her ass to the sky, to let the werewolf emerge. Her sphincter tented. Her clit was electric. She could feel that little swelling in her pussy that foretold a squirt of lube. Breasts, pussy, ass--all filling and fit to burst.

There was another punch of growth against her sphincter, and the pressure in her ass was rising rapidly. She began to shake, riding a wave of stimulation to a crest. She sucked hard on his dick, and he paused, planted in her throat.

"God," he muttered, "that's so fuckin' hot."

Her rage soared, and she came with a fury that she'd never imagined before. She came from her pussy, squirting lube several feet with an orgasmic clench. With a thrust of her hips, her asshole burst open, cumming violently as she pushed the monster within out through her ass, and a black wolf's tail, damp but thickly furred, squeezed out of her horny butt five inches in a single shot, pushing away the damp flap of her sliced panties and rubbing the hairs apart against her muscular asscheeks. Her nipples crescendoed together, and she cummed from her humongous breasts, hot milk spurting out in twin jets on the hardwood floor.

"Fuck!" Ben shouted, but he didn't dare pull out.

The tail drove Heather wild. She was spitroasted by Ben and her own transformation. The texture of fur and the stiffness of her tail was a buttfucker's delight. She urged it to grow, squeezed and pushed it through her asshole in jerks and twitches.

Milk squirted irregularly from her huge jiggling tits, each one a massive mound of soft pleasure hanging lewdly from her chest.

Her bulging pussy thundered with orgasm, her cumming clit pounding. Every nerve in her vagina was burning with erotic energy, making her feel like she was cumming deep inside. Her clitoral bulbs were swollen violently tight. It would've taken a jackhammer to penetrate her pussy.

Heather's thoughts were simple and raunchy. Grow tail! Yes, force it! Grow out of my ass! This is how a butt slut grows a tail. This is how she becomes a monster. Yes!

Ben wasn't going to stay hard like this, but Heather didn't care. She'd already cummed from sucking his cock. She'd already begun erupting from her human skin, tail ripping its way out of her asshole, an intense explosion of pleasure with every jutting inch. She pulled back off his cock, and the moment he was free, he danced back, big dick wriggling and slimed with her saliva and mucus. Just looking at his penis filled her with a kind of dark, strange envy. It'd been his last chance to enjoy dominating human Heather. The beast didn't like that.

The beast wanted to dominate him.

She took a deep breath, lowered her head down till her right cheek rested on the floor and raised her bare ass high over her knees. Her smooth, fat pussy mound ached and swelled a little more between her thighs, the stiffness of her clitoral bulbs somehow increasing. Her stiff tail rose between her buttocks like a flagpole, black fur puffing out near the drying tip. This bent over position spread open her ass the most. She grunted and strained, and the monster inside her grew faster. There were cracking sounds, and her bottom quivered with anal pleasure. The tail was a foot and a half long. She squeezed to push out more, and with soft wet cracks, it slid and slimed out to two feet exposed. She made animal noises, and her breasts pressed into her own milky puddles, still dripping from her thick, stiff nipples.

She lifted herself a little onto her monstrous hands and looked up at Ben. "Jerk off."

He was half-mast now. "What?"

"You fucked my face so hard that I started milking. Now look at my tight ass and jerk it!" She shuddered and a slow inch protruded from her butthole. "Jerk it!" she shouted. The beast's instincts were filling her brain with renewed aggression, and the anger was making her blood pound between her legs. Her puffy pussy mound was blushing, the skin beginning to feel a little pressure. Her vagina was so agonizingly aroused. Her clit itself began to feel strange, as if underneath her skin, it was changing shape with every beat of her heart.

He looked down at the mess of Heather's fluids and her oversized breasts. He smelled her horny pussy and witnessed its growing animal bulge. He stared at the tail bursting from her bottom, and he began to stiffen again.

"It's kind of hot," he said. "Does that feel good?"

"Fuck yes," Heather muttered. Her tail was nearing its end, just a few inches shorter than her legs, maybe two and a half feet in the open air, another 6 inches pinned inside her. There was maybe three inches left to extend.

Ben began to beat off slowly, getting harder and harder. "Can I play with those tits?"

Heather said nothing. She'd force him to "play" in a minute. She concentrated on becoming the beast. Her feet began to stretch and pop. The skin on her soles was pulling taut, ready to tear, but she barely cared. It was everything in her pussy and ass that mattered most. Inside her groin, she could feel flesh moving and shifting. She couldn't identify many of the other parts inside her--she hadn't felt them all before--but some shrank and slid, and others dropped and swelled, and in the totality of her transformation, she could feel the beast was pushing its aching, erotic flesh towards her pussy mound, which gave her the strange sensation that her vagina was filling up from within.

Ben was muttering to himself, talking about her ass, her nipples, her tight wet cunt. He was psyching himself up, digging a new place in his head for a new fetish.

"The tail is kinda hot too," he said experimentally, and that thought seemed to give him a surge of pleasure, because he walked around behind Heather and started beating off over her ass. "God damn. Look at that pussy girl, you're dripping!"

Right in his shadow, her bare feet split open, soles breaking away from their tops, and werewolf's feet jutted forth with glistening claws. She grunted, feeling the flesh begin to split up her calves towards her knees. He was so enamored with her pink pussy lips, he missed the shift for a moment. Then there was a wet sucking sound, and the meaty, sensitive erectile tissue behind her human clitoris pushed rapidly down beneath her labia, snaking thickly from the old base of her clitoris down towards her taint, followed by two more aching masses that pushed out of some inner pocket and poured tightly into the space behind her pussy lips on both sides of her throbbing clit-pipe. It was so sudden it was painful, but it hurt so fucking good. She shuddered violently with arousal, and Ben stepped back, a little frightened by her reaction. Heather clenched and squeezed involuntarily, but she couldn't produce enough force to birth the hefty contents of her human vagina. The pressure only rose, and as her round butt shook, she felt her bulging pussy lips literally jiggling between her thighs, insanely full of aching, horny, beastly thickness.

"My asshole," Heather whispered, "and my pussy too." The pressure and pleasure was reaching a new peak. She felt as if her whole rear might rip open. The beast was so eager to be born!

"Fuck yeah, you're hot," Ben said.

She began to grunt, and the grunting turned into squeals. "My asshole!" she shouted, "My pussy! Everything is so full! So fucking full!"

Ben was beating off fast. He was angling his dick down, as if he could go for her huge pussy, just push it in while she did her thing.

She felt the last three inches of tail grow and bunch up in her rump, making her asshole feel intense pressure to the point of explosion. She felt her monstrous package of flesh pumping up inside her massive human pussy, thicker, fatter, hornier, growing impossibly tight with arousal, until her pounding labia and human clit felt equal parts rage, pleasure, and erotic pain!

He suddenly pushed his cockhead between her pussy lips, but her pussy was already full, literally cockblocking him, and she felt his dick jamming painfully against the hot girth of the beast's bulging, veiny flesh. "What the fuck--"

Heather roared hatefully, her tail rocketed out, and her next anal orgasm shot through her body like a lightning bolt. Ben darted back a step. With a meaty rip, her asshole burst and her tail zipped through the flesh over her ass like a pencil ripping paper, straightening instantly. The surge of anal pleasure made her human pussy bulge again, swelling bigger than a clenched fist, stretching and spreading her pink human vagina wide enough that her inner labia were pulled apart. Just within her sweating human snatch, he could see hints of the crimson, turgid beast, aching to cum!

Heather stood slowly, legs bowed and spread apart, her milk running in rivulets off her incredibly large breasts, droplets tumbling from her erect nipples. She snipped away the elastic band, ruined panties falling from her hip. Her werewolf's tail whipped repeatedly, slinging out moisture, puffing out the fur. Her crotch was pounding. Her rage was straining to rip out of her horny cunt, to be violently born through her tight little hole. She was heaving with fury. "You want my pussy?"

"I'm sorry babe!" He stepped back, realizing too late that he was now up against the wall.

Heather stalked forward, stopping at most a step or two away, and reached down to her fat pussy lips with her monstrous hands. "Let me show you what's inside my pussy!"

"Please, don't!" Ben shouted.

She breathed deep, faster, faster, heavy breasts bouncing, then threw her head back and howled. She clenched up human Heather's thick labia, and with a furious grip, she yanked her pussy lips apart. The pressure in her pussy mound spiked into the ecstasy of release. She could feel her bulging labia peeling back. The tear started at her vagina and shot up through her human clit, violently cumming its annihilation. The loud wet rip of tearing pussy was audible over her howl, and her final vaginal orgasm was tenfold stronger than anything she'd ever experienced, exploding through her entire crotch with a violence matched only by her transformation.

The straining, horny beast package burst out of her bulging, cumming cunt. She could feel the hot, turgid flesh of her thick new werewolf genitals surging through her ripping vagina. A giant crimson cock erupted wetly out of her pussy, untucking her hidden girth from between her spreading pussy lips and instantly whipping out of her snatch into an awesome, throbbing, foot-long erection, her flared cockhead jutting lewdly out of her tender foreskin. The orgasmic tear swept down towards her taint, cunt still cumming apart. Pussy lips screamed in pleasure as she yanked them back over and over, aiding the furious birth of her gigantic, black-furred balls. Then with one final pull, her taint split entirely, connecting her labial rip to her annihilated human asshole, and her massive nutsack burst out of her crotch and flopped between her soft thighs, heavy and aching with potent semen. She yanked her tattered labia back towards her hips, still baying with triumph and fury.

Fuck you, Ben! You wanted some pussy? Then face my raging, cumming cock and balls!

Thrusting her hips forward, feeling her fat nuts slosh between her thighs, the last pulse of her final vaginal orgasm rushed up from the base of her thick dick, transforming within her aching crimson cockhead into furious ejaculation. Still howling, Heather jizzed rope after rope of thick white semen, at first painting the bottom of her breasts in sticky hot cum, then grabbing her huge crimson cock and aiming it blind towards Ben. To her deep pleasure, he shouted with surprise as she hosed his naked body with smelly, sticky friendly fire, her first phallic orgasm pulsing over and over through every joyous inch of her thick, veiny genitals from dickhead to ballsack, generously showering her massive cummy load all over her squealing boyfriend.

Her werewolf cock and balls still dripped with her human pussy lube, smelling strongly of vagina and penis both. She let go of her dick, letting the howl die in her throat, and she relaxed as the last of her orgasm spurted from her cockhead and spattered on the floor. She looked down at her new genitals, admiring them. Where the base of her clit had been, her cock now stood--naked, red, and rising from her thick black shewolf bush. Where her fat labia had lain, her fatter ballsack now hung, coated in black fur. From the front, she could only imagine that her dick looked even longer, and it made her even prouder. She was dominant, female, and most importantly, she was happy.

Time to be rid of the passive human Heather. She grabbed the ruined tatters of her vagina and pulled further, peeling back the skin around her hips like two sheets, ripping her stomach in twain up to her belly button, then yanking down and back to rip the human flesh free from her waist, splitting it from her back, pulling it off her thick asscheeks in sheets and letting both halves hang from the skins still wrapped around her legs.

She looked up at Ben. He was plastered to the wall, breathing rapidly, coated in shewolf jizz from the chest on down, and in front of him, her cum dripped in clumps down the jutting length of his rock hard, eight inch cock.

"Jesus," he whispered, "nice dick." Heather's massive, cumming shewolf cock and balls had begun as a shocking surprise. Her pussy had ripped apart with a meaty, wet, rubbery burst, giving loud, violent birth to a monster's penis and testicles. But then as she took her turn raining semen on him, he'd realized something about himself that he'd only vaguely understood before today, something that'd drawn him to Heather's aggressive, dominant personality.

As she'd painted his dick in cum, he'd realized that he liked when she pushed him around and used him for her pleasure. He liked being cummed all over with a beautiful woman's jizz. He also realized that he was turned on like crazy by furry bestial women, even those with cocks.

Heather's eyes had changed to a golden hue, animal and dark. "No more pussy, ever again," she said in a slightly deeper, huskier voice. She lifted her ballsack as if to show him, no vagina hidden back here. Only fuzzy taint. The howl had traced her inner transformation. This final metamorphosis had been triggered by the sundering of her human sex. The werewolf was all that remained underneath her human hide, ready for the final and most personal part of the transformation, something even more important to her identity than her new penis.

Heather reached down with her right hand and gently jacked off, stroking her footlong to keep it hard while looking at his erection hungrily. Then she let go, and her erection bobbed between them like a dowsing rod, always pointing towards his crotch. "Do you like it?"

Ben looked up and down the length of her penis, too embarrassed to say how she turned him on.

She took two steps forward, and in motion, she grew a half foot all at once. Her bulging, lengthening legs burst through their skins, which peeled off one after the other, leaving her beautiful furry thighs to be wet with her juices. The remaining skin seemed tighter on her body, on everywhere but her beautiful human face.

She stopped in front of him, massive breasts jiggling as she settled against him, his big cock batting gently against her even bigger cock. She licked her lips. There was still a mess of lipstick on her lower lip, where his ballsack had rubbed it around. "I think I win," she said, sharp teeth flashing, "so it's my turn first."

"What?" Ben asked. His dick was throbbing so hard it hurt. He didn't dare look down, but he could feel their swords crossing. She was so warm and huge against him. He could feel his glans rubbing ever so slightly against her slick foreskin.

Heather grabbed his dick with her left hand and drew him forward, pulling his hips away from the wall. His cum-spattered chest pressed into her giant, milky breasts. Then she slapped their dicks together in one loose grip, and she started frotting with Ben, slowly jacking off both cocks and rubbing their stiff thick shafts together. "Feel your girlfriend's boner..."

"I do," Ben said breathily. Heather's fingers ran over his cockhead, smushing it tight to her girth. She was genuinely throbbing with a rapid heartbeat, clearly turned on just as much as him.

"Who has the bigger prick right now?"

"Y-you--" Ben stuttered before moaning. He was about to cum if they kept rubbing dicks together.

She must've sensed how close he was, and she let go, pulling her hips away, their erections sticking together so very briefly with her cum. He gasped, slumping back into the wall. "Then it's my turn first," she said. "On your hands and knees, you prick."

Ben hesitated. He was turned on, dear lord, he was... "But I've never--"

Heather slammed her hand on the wall next to his head. "I have taken it up the ass, repeatedly, and I will again--if you're still my boyfriend."

"If?" Ben asked, terrified by the claws she was slowly pushing into the wallpaper.

She pushed her face closer to his, smelling his sweat, his fear, and his arousal. She was his height now. Her ample breasts swayed a little, a mesmerizing beauty. "You said you wanted to break up. Look how angry you made me."

"I'm sorry," he whispered.

"I'm not." She reached down to a breast and gently stroked her erect nipple, rubbing the whole areola in a circle with her thumb. "Mmm. I can't wait to finish." She glanced down at her fat erection, then grinned at him. "We'll suck each other's dicks later. I need a butt to fuck. Now."

Ben was breathing fast. The image was in his head. On all fours, his busty girlfriend mounting him with that huge red cock, slowly filling his ass. "Can you wait a second?" He needed to think it through, even as his sphincter winked and his asshole ached with anticipation. He had to consider the outcome, even as he began to imagine how fullness might feel...

Heather scowled briefly. "Ben, do you want to fuck? I can feel your fucking boner."

"I do, but--"

"Are you my boyfriend?"

"Yes, but--"

"Ben! I need a decision. Either leave, or get down on your hands and knees."

Ben closed his eyes, swallowed, then whispered, "Will it hurt?"

Heather smiled at his first time anal jitters. "Not if you let me teach you."

Ben opened his eyes, nodded slightly, and pushed away from the wall. Heather stepped aside and let him pass, walking out of the kitchen and into the living room. He clambered up onto her couch, back to Heather, and sat on his knees, looking back at her pensively.

Except for his trimmed bush, most of his body hair was shaved off for swimming. His naked buttocks and thighs appealed to her. She touched her hard dick reflexively, imagining how good it'd feel to slide her girl cock between his asscheeks. She stopped behind him. He was clamping his legs together, so she couldn't even see his genitals. She put one hand on his back and pushed him over, and he gently toppled onto his hands.

"Heather--" Ben began.

"Shh." She was shuddering with anticipation. Gently, she reached down with one hand and teased at his right thigh. He spread his legs a little, and his ballsack--large for a human and hanging low from the heat--flopped down between his thighs. His big dick waved just in view, bobbing under his belly. Ugh, his butt looked so fuckable. The remainder of her human skin started to blush with pre-transformation heat. This was why she'd wanted a boner--this fantasy of femdom that she'd barely understood as a human because she'd been so intent on submission to cocks. Now that it was her cock and his submission, it made far more sense.

"Do I need lube?" Ben asked.

"My cock is slick with pussy lube," she said, "now shush or I'll spank you." She grabbed his hips and pulled his waist back a bit, whispering, "Push your ass up and arch your back. Lower your chest to the cushion. There you go." As he complied, she saw his fit ass rounding up, pushing up, and then spreading cheeks naturally to bare his asshole. Below his taint, she could see her cum clotting on the bottom of his testicles after it'd dribbled down his dick. She started to drool--she was so ready to clamber up, mount his ass and make him into her butt slut--but she had to make sure Ben was okay. She wanted this again and again, so he had to enjoy it.

Ben was shivering a touch too. He could feel his vulnerable ass, presented so lewdly to a shewolf with a penis. In a moment, he'd be thrust into, rocking back and forth as her hips slapped into him.

"Here, support your body with these pillows. You aren't used to it yet." She stuffed a couple under his belly and chest, leaving enough room that his hard dick could hang freely under his body. "I'll hold up your hips, so just relax."

Ben nodded, shaking harder as the moment approached. His butthole was beginning to feel aroused. It was so filthy! Her dick was so huge! His asshole felt so small--he could hardly imagine how it'd feel if she started packing his anus full of girthy girl.

"That's the secret, okay?" Heather was sweet to him despite the intense lust that made her want to jump on his ass and howl and hump wildly and empty her huge girly wolf balls in his tight tush. "No matter else what happens, just relax. Don't tighten up. Just completely relax and let me in, and you will feel incredible. It will be the best sex you've had since the first time you fucked my ass." She gently patted his horny butt. "Trust me."

"I do," Ben said, now positively quaking with arousal. He couldn't believe it. A big dicked woman was so hard for him, so ready to peg the shit out of him, and it was his Heather! His girlfriend!

She clambered up on the couch behind him, slowly jacking off her big werewolf dick. Ben moaned when she petted his ass with her furry werewolf hand. Then she peeled back her foreskin and slapped the upper reach of her girthy cock into his asscrack. She rolled her hips, sliding her cock between his buttocks, back and forth, hotdogging his rear. "Are you relaxed?" she whispered.

Ben arched his back and pressed his butt into Heather's big girly dick.

Heather pulled back her hips as far as she could and guided her cock down between his thighs. Then she let go, and the strength of her erection whipped up to lift Ben's ballsack, one testicle flopping on either side of her throbbing hot shaft. "Let me see," she whispered, and she curled her thumb to retract a claw. Then, slowly, she ran her wet thumb down his asscrack and touched his tight little butthole. Ugh, it was so hot. Soon, she'd fill him up, right here. She'd buttfuck the werewolf right into his body. Then, the new Ben would begin hatching through the same hole.

She pressed into his sphincter, and his resistance was brief. Then, with a soft, pliant push, she buried her thumb up to the first knuckle in his hot wet asshole. Ben sighed, waiting calmly for her to keep going. He definitely had figured out how to relax. Good. She pulled out, then grabbed his hips briefly and sawed her erection into his nuts. It was soft and intimate. "Ready, babe?"

"Yeah," Ben said, "yeah."

She pulled back, grabbed her footlong monstercock a couple inches behind the flared crimson glans, and she pressed her cockhead between his cheeks and against his asshole. There was little resistance, and the way he pushed into her prick suggested a hunger for her approval that made Heather feel like a big-dicked queen.

It was time to let go.

She grabbed his hips, and with a slow, wet, slimy thrust, she sunk six inches of her brand new dick up her boyfriend's butthole.

"Oh my God!" Ben shouted.

"Relax!" Heather hissed.

"I am," he said, "but oh my God, Heather, you're huge." He started panting. The cock stretching open his sphincter was slick, veiny, and girthy as hell. It was so warm and stiff. Heather, his girlfriend, was inside of him, and his entire butt felt so full. He could feel his aching, horny prostate pressed upon by her dick. His own big dick--big for a human--throbbed between his legs.

Heather pushed a little deeper, and another inch of shewolf cock disappeared into her butt slut boyfriend. His asscheeks were soft and tight, rubbing against the sides of her penis, but his sphincter was clenching repeatedly down on her massive crimson dick. "I'm going the rest of the way, okay? Just relax as much as you can."

"Okay," Ben said, "Just..." He paused, unable to believe he was saying this. "Fuck me hard."

She would absolutely do that, but to start, Heather had a little restraint. She'd been a total anal slut as a human. She knew how it felt, and she loved that he was finally feeling a deep buttfucking, so she would fuck him right. They would both get a lot of pleasure out of this.

With one long, slow stroke of her hips, she buried the rest of her cock inside him, right up to the broad base. He was practically being double-fisted anally, in terms of stretching, and he was taking it like a pro on his very first try. It was something about her juices, she knew. His skin was already a little less him, already a little more flexible and erotic.

Ben felt his asshole stretch open to a gape that was beyond belief. His butt was being forced open by sheer girth, and he could feel her big fuzzy ballsack flopping down onto his ass. Heather was a werewolf, and she was fucking him. His asshole was pounding with pleasure. His vagal nerve was making that sexual throb in his groin, through his belly, and up along his spine, right to the nape of his neck. His prostate was squeezed so hard against the bottom of her cock. He ached.

Heather hissed, feeling her new cock sheathed fully inside her beloved boyfriend's body. No wonder he wanted to buttfuck her so often. The grip of his rear was intense. She pulled back her hips a couple of inches, and she felt his sphincter tugged back a little bit, scraping along her dick. He squealed with pleasure. She pushed back in, plunging her cockhead through all that warm tight boy, and she felt his sphincter sink into him a tiny bit, like she was packing his ass deeply. He groaned encouragingly, clearly lusting after her massive dong with his aroused ass.

She pulled out a little further the second time, going a little faster. Ben's prostate ached and rubbed her just beyond the inner walls of his ass, and his sphincter screamed like a ring of hot anal pleasure. As his prostate was pumped, he could feel his cock straining to cum. His cockhead was flared and pushing out of his foreskin. He wished he could reach down and jack it, but her weight required both arms and legs, and if she wanted to give him a reach around, she would.

Heather pulled back further and faster, almost six inches back, the full extent of what she could manage with her hips. Then she slammed her werewolf cock up his ass, and this time he just gasped with joy when she filled him. Yes! He can fucking take it.

She started to steadily piston him, her breasts sloshing on her chest and her jaw tightening as she pleasured her tremendous crimson cock. She loved feeling her tender testicles flop with every stroke. She loved being a shewolf. She loved that the monster within had ripped open her pussy and let out this furious hateboner. The she-beast could finally fuck him like he deserved.

His buttocks bounced and jiggled with her strokes. His stretched, horny asshole filled his groin with the pleasure of anal sex. Beneath the base of his flopping cock and deep in his ass, his prostate spiked with pleasure every time her cock pushed in, pushing down against the gland. It made his steel hard erection pulse ever higher, even though nobody touched him.

She picked up the pace. Her dick scythed down into his ass with a wet slorch. From behind, she imagined she looked amazing, her big girly ass mounted up over his, their ballsacks hanging one over the other. She yanked back with an anal hunger--then she needed to bury herself again, to raise the pleasure of her cock one stroke at a time, rising slowly towards final release!

She could feel her face slowly shifting beneath her skin. She could feel the bones crunching and changing bit by bit, forming a nascent muzzle behind her gorgeous lips and petite nose.

Her breasts grew as she pumped his asshole. Every stroke seemed to fill them tighter with new milk. She became more feminine as she buttfucked him. She became more beautiful and dominant and powerful. She loved feeling her breasts grow, and their pleasure encouraged her to fuck him harder and faster. Bigger, she thought, my breasts have to be bigger!

Ben was moaning constantly, his voice bouncing when her hips slapped into his rear with a sweaty smack. His asshole was being fucked looser, even though he'd already relaxed. His butthole would briefly gape when she pulled out. His prostate was almost milked--the pressure of her dock was squeezing him until he would burst and spray cum on the couch. His sphincter was spasming, trying to grip her cock. His horny butthole was throbbing, packed so full of pleasure that he feared he was only seconds away from a massive anal orgasm. "I'm near," he said.

Heather heard him and reacted by losing control. She grabbed his hips, almost sinking her claws into flesh, and she started to hump her boyfriend with feral intensity. She dragged him down over her dick at the same time she slammed her hips forward. Her gigantic cock was a foot long pole of near-orgasmic steel. His hot, wet, tight, fuckable butt was yanked up and down her crimson dick, stroking veiny, sensitive foreskin and flared, aching cockhead.

"More, more!" Ben shouted, "I love you, Heather, more! Yes, yes, oh my God!"

Heather felt beautiful. She felt wanted. She felt her cock and balls edge up to orgasm, and she knew her humanity was absolutely done. Goodbye, human Heather. Hello, werewolf within.

Ben's asshole clenched around her sexy girth. His prostate pulsed. He'd been stroked and milked beyond his limits. "I'm cumming!" Ben shouted.

Heather let go moments before she jizzed. Her face cracked violently, her head shifting, her nose flattening as it was stretched over a clear muzzle-shape. She closed her eyes and grabbed her skin at the very top of her breasts.

Ben's butthole cummed, his body quaked, his prostate unleashed a torrent of fresh semen, and he started spraying rope after rope of hot smelly cum on the couch beneath them.

Still buttfucking his cumming ass, hips stroking and shaking, Heather clawed at her massive, milky breasts. Claws dug in and pulled the skin on her chest apart like a thin t-shirt, ripping it down into her freshly bulging cleavage, where two dark shewolf breasts bloomed larger, each as big as her head and under pressure inside her human hide. They squeezed up and burst outward, nipples popping out of her hide. They bounced wildly, spurting lines of white milk from black nipples. She instantly separated the skin down to her belly, then pulled up, splitting her throat. Her flared cockhead was throbbing, about to blow her load up his ass and empty her big horny balls. Her muzzle jutted forward, stretching her skin like a tent over an elongated face.

Ben felt incredible, riding on wave after wave of anal pleasure. He'd never jizzed this hard in his life, and in this moment, Heather was his beautiful beast girlfriend.

Heather came and became, losing her humanity at once. Her lips split in two with snaps, and her nose ripped open, and her chin ripped open, and her brow burst apart, and her scalp split, and her massive girl cock cummed! Howling in triumph, she ejaculated a massive, hot load up his butt, and a black werewolf's head burst through Heather's splitting face, fully formed from the final spurt of growth. Her hips slammed his ass, driving her jizzing dick up her boyfriend's asshole. Her balls slapped wetly on his butt and pulled tight, emptying their massive loads of semen. Rope after rope of potent cum surged out of her, and she quaked and shuddered with orgasm--her reward for shedding her humanity. The shewolf grabbed handfuls of blonde hair and ripped her scalp apart with ease and gusto. The empty halves of human Heather, now a simple mask, were pulled away like a hood--a costume of skin that werewolf Heather had hidden in for her entire life.

Still howling, she came again and again. Her tail stood straight out over her sexy ass and fat sack. Her big cock was plugging Ben's cumming butthole. Her monstrous nipples sprayed milk out of her werewolf breasts. Her wet mane of black hair fell to her shoulders as her human skin sloughed off her broad furry back like a discarded robe and fell to the floor.

Yes, yes! Finally naked and free! Out of her frail human body, a werewolf had been born!

Ben ran dry, panting. The anal release had been everything he needed, and he hadn't even thought about trying anything so submissive until Heather's pussy had split open and disgorged her immensely sexy cock and balls.

Heather went through some final aftershocks, slowly pushing and pulling her cock through his ass, feeling little gushes of jizz and pleasure when her foreskin was pulled all the way back.

"You're a fuckin' werewolf?" Ben asked, exhausted.

"I became one." She held onto his hips, breathing deeply. "I hatched."

"Do all werewolves rip off their skin like that?"

"I think so," Heather said. She traced her silhouette with her hands. She was sexy, taller, and better proportioned. Her huge breasts were easy to carry on her new frame, and she felt that once her milk was dried up for the day, they'd become more compact.

"How do you change back?" Ben asked. He was starting to angle his ass to see if he could slide off her prick. He couldn't, not while she was hunched over him.

Heather shook her new dark head of hair to break up the damp clumps and dry it out. She didn't answer him, because it'd be best if he guessed the truth on his own.

"Heather?"

"Hold still," she said, feeling her cock soften the smallest degree. She grabbed it by the base and started pulling out slowly. Her cum began to gush around the edges of his sphincter and run over his taint and balls. The load was far too large. "Try closing your asshole tight."

"Why?" he asked.

"Don't be stupid," she whispered, "You know why. Now, keep the cum in you, okay?"

"Am I infected?" He didn't sound scared, just unnerved.

"You're my boyfriend," Heather said, "You need a little bit of me inside you to change." She hesitated. He wasn't clenching his sphincter on her softening cock. "Please, Ben."

"If I don't have your cum in me, I don't change?"

Heather placed a hand on his soft buttocks and stroked his red skin where her hips had spanked him. "Yes, I think so." She pulled it away. "Don't you want to be with me though?"

"Yeah," he said, but he didn't move.

"Are you scared?" she asked.

"No, it's just..." He twisted his body and turned his head to see her lupine face in the corner of his eye. "Were you infected by a werewolf? A different werewolf?"

Heather smiled and laughed--a high, girly tittering. Werewolves had lips, and her expression was still clear to her partner. "Ben, I didn't cheat on you. This just happened to me. It was sudden."

"How?" he asked.

"I let the anger and lust out, and the wolf I became was too big to fit in my skin." She reached down to her breast and gently stroked her nipple, rubbing the whole areola in a circle with her thumb. She grinned. "It felt so good to let it all out."

Ben's dick was stiffening sympathetically.

"I was so angry with you," she said, "God, I couldn't believe you wanted to break up with me." She stopped petting her erect nipple and draped herself over his back, invading his personal space, letting her big dark breasts settle on his shoulders. "You don't want to break up anymore, Ben?" She reached out and put a hand on the side of his neck, a loving caress. He relaxed his body, but he began to squeeze with his asshole, and she knew he'd accepted. "Thanks, babe," she said.

He concentrated on keeping the cum in his ass while she pulled out inch after sticky inch of half-erect dick. "You never answered. When do you change back?" he asked.

She slipped her muzzle up to his ear and whispered through her flexible lips. "We don't." She licked his cheek. He wasn't as frightened as she expected. "Do you love me still?"

"I do," he said.

"You know your friends are jealous that you have me."

"I know."

"You were weak."

"Were?"

"Mm-hmm." She pulled out the last inch of her cock, and her glans came loose with a soft pop and a surge of cum that poured out of his anal gape and down his thighs. Ben shut his eyes and clenched, and quickly, his asshole closed, holding onto the majority of her beastly load. "Good boy," she said, dropping her huge crimson cock to dangle between her spread legs.

He turned over as Heather sat back onto her knees on the couch. Even while turning flaccid after an orgasm, she was obviously well-endowed, and her werewolf breasts were absolutely immense, even after spraying milk all over him and the furniture. He scooted off the couch and stood, and she looked up at him with a relaxed expression.

Black fur covered most of her body--penis and belly excluded. Her stomach had less fur and a dark grey color, and her palms, areolas, nipples, and feet were clear. Her hair was a gorgeous cascade of shining raven black, catching hints of shimmering blue in the light. Her bore was a feminine, slender muzzle, and her golden eyes cast a warm gaze over him.

"So when do I change?" he asked.

"You'll feel it soon," she said happily.

"What's it like, transforming into a werewolf?"

"For you? You'll play with my body," she said, cupping her breasts and making them jut out even absurdly further. Milk spritzed out onto the carpet. "Then you'll be so horny, you'll burst out of your skin and become my big-dicked beast."

"I'll look at your full moon of an ass." He reached down and touched his dick, wondering how he'd get another boner that fast after just cumming. "Then rip, wolfman?"

Heather got up off the couch, looking rested enough to stand. "You're mine," she said softly.

"Just us two?" he asked. Then he paused and blinked. His skin was becoming rapidly flushed, and he could feel his cock stirring. "Fuck," he muttered.

She knelt down in front of him. "Become hard for me," Heather said. "Get really hard. Harder than you've ever been." She squeezed her arms around her humongous breasts, and milk jetted briefly from her plump nipples. "Get hard for my tits." She leaned forward, and with her broad tongue, she licked the underside of his dick from testicles to tip. Her tongue was huge, wet, and hot, and holy shit, his cock was getting hard fast.

"You can suck my wolf cock, once you're all the way up," she whispered huskily.

Ben grunted. His werewolf girl was teasing his prick, but it was a welcome touch. He was wrestling with a new tension in his body, grimacing otherwise.

There was a cracking sound somewhere in Ben's spine. He put his legs apart and strained to handle some sensation. "God, there's pressure."

"Where?" Heather asked.

"My dick."

Heather looked closely. Her breath tickled its wet length, and his eight inches swelled a little harder, the glans turning grey as it pushed out of his foreskin. She licked him again, balls to end. "Nine inches," she said.

"Damn, Heather." Ben's dick swelled up even more, becoming thicker across its entire bulk. "My foreskin, fuck!" His foreskin was starting to constrict his cock. "Why isn't it growing?"

"What?"

"My foreskin!"

"It's not your skin anymore."

He gasped. The sensation must've changed. His face lit up with surprise.

"Sensitive?" Heather asked.

He nodded rapidly.

"Yes!" Heather was ecstatic, clapping and shaking her milky chest. "Get hard for me! Get big! Show me that werewolf dick!"

He stared at her tremendous, dripping breasts, shaking and bouncing. Down over her thighs, she was already sporting a half-chub curve of foot long girl dick. "Oh fuck." He looked down at his foreskin. As much as his dick head was turning grey, his foreskin was turning white. It was stretched far too tight. The bowstring connecting to the head of his cock was taut and pulling back. "I'm gonna break. Oh fuck!"

"Hatch!" Heather yelled.

A wave of dizziness struck him, then passed. Suddenly, there was a look of great confidence on his face. "I feel it," he said clearly. He looked at his hands, then down at his dick, pointing at Heather's wolf-head like a dowsing rod.

"What?" Heather asked.

"Your breasts are making me hard--nngh!" He began to visibly concentrate, to strain to release something. He growled deeply, and in meaty twangs, his dick began to grow again. The bowstring stretched beyond capacity and snapped, a gunshot of pleasure that shot down his dick to the very base. His human foreskin had transformed from a single part of his penis into a flimsy wrapping.

"Hot!" Heather cried. She reached down and started stroking her gigantic cock with both hands, getting her own crimson erection to swell to a full salute.

"It's wider than this," he said fiercely, "It's longer!"

Heather masturbated with delight while Ben's real cock emerged. It slithered out of his foreskin like a snake, inch after inch. Then it stopped. It could grow no more in this container.

"This skin!" Ben shouted. Huge claws burst from the fingers on his right hand, sensitive fingertips disintegrating into stars of pleasure. He reached down to the front of his cock, grabbed hold of the thin, overstretched flesh at the base, and ripped the human skin off his giant beast-dick like it was a condom. Every inch unveiled instantly swelled a whole inch wider. More cock, he needed more! He had to show Heather his own humongous werewolf genitals. When the tube of flesh snapped off his cockhead, the entire shaft and head erupted another inch from his crotch, forming a full foot of smoky grey penis, fiercely erect over a werewolf woman's sexy body.

Ben was panting heavily. Heather was delighted, beating off enthusiastically. They were lovers, boy and girl, sharing the experience off having big werewolf cocks together. She reached out and lapped at the underside of his flared head. His eyes rolled back and he roared as he released the pressure in one final explosion. His nutsack split open, and his expanding balls dropped down into a great grey furry nutsack. His cock jutted two more steel inches from his crotch, reaching its final and full size, and the tip of his massive dick erupted, jizzing a pint of hot semen all over Heather's muzzle, hair and humongous tits.

She laughed in the cum spray and waited until he was done to open her eyes. A couple of ropes had landed across her cock, and she rubbed them into her foreskin and glans with sticky hands.

He ran a hand over his monster dick, still erect as steel. "Turn around," he said, without even waiting for Heather to wipe away the cum spread on her fur.

"Oh?" she asked with faux naivete.

"Ass!" he ordered.

She spun around gleefully and got on her hands and knees, arching her back down and raising her tail high, letting him see the depth of her black furry asscheeks and the tightness of her dark little asshole. Her cock was bouncing beneath her, the tip of her dick nearly brushing her breasts. Her big balls jiggled between her thighs while she wiggled her ass invitingly. The black werewolf was ready to be mounted from behind.

The grey werewolf-to-be leveled his huge penis against her bottom, found it slick and inviting, and shoving aside her cheeks, he pushed his thick rod up her asshole.

Heather closed her eyes and relished that first moment of the buttfuck, when the dick speared and spread her sphincter. Her asshole tingled; her tail wagged. Then Ben pushed in, and slowly he packed her butt full of dick. She moaned and felt a wellspring of pleasure deep in her loins. His cock was rubbing on the far side of her prostate, squeezing against it through the thin wall of flesh inside her anus. Her stretched butthole was stimulated, waiting to reward her when he pulled out.

"Fuck yes!" she shouted, "Fuck that butt!"

"God, this ass," Ben said, "This fantastic fucking ass!"

His monster cock was buried to the hilt, and her asscheeks were pushed aside by his amazing girth. His furry balls rubbed gently against her taint, resting just above her own nutsack. He was all the way in, the first stroke halfway done.

Heather moaned. Lust raised the fur on her hackles and she shivered. She reached below herself and loudly beat her meat. He pulled back nearly half a foot, slowly tugging out on her sphincter, then rammed it home, a surge of pleasure in her butthole. She stopped masturbating, bracing herself against the floor and pushing her ass up and back into Ben. In and out. In and out. She was an anal queen, and the sudden addition of her prostate was a welcome change.

Ben picked up the pace and grunted with every swift hump.

Heather's whole ass felt erotic, arousal beating out of her sphincter like shockwaves. The pleasure spread across her rear, collecting in her aching balls and crawling up her flopping werewolf cock. Her breasts swayed, nipples straining to cum again. But best of all, she could feel him shifting and crackling as he fucked her big ass. His hips slapped on her round bottom, and his slick cock tugged on her buttocks, making her muscular cheeks slap and shake with his strokes.

"Heather." He grunted with the effort. "I'm feeling it."

"Ungh." She could barely talk. Ben's giant dick was reaming her butthole at top speed, and her breaths were short and sharp. "What?"

"I can feel it. I'm going to grow a tail."

Heather felt a pang of lust. "Squeeze it out!" she shouted.

"I want to transform..." He groaned. "I want to be your werewolf."

"When you hatch," Heather spoke through his strokes, "cum in my bum."

"God, you're so fucking dirty." He had his hands on her hips. Now he squatted down over her bottom and leaned over a bit. Her tail was pinned to one side, and he was rolling his hips to continue deep dicking her ass. "Fuck, this is going to make me cum."

"You only transform once," Heather said, "enjoy becoming a monster!"

"God, this ass! You're so fucking tight!"

"Your dick is bigger than mine!" Heather shouted joyfully.

They were both getting wildly aroused. He was going to transform while his monster cock was buried in her asshole. It was so grotesque, Heather could hardly believe it. Just an hour ago, she'd wanted a buttfucking, but she never could've imagined this. It was so raw, so animal. He was taking his turn to penetrate her ass.

Ben was getting into it too. He was into becoming a beast like her. The erotic explosions in her belly felt like fireworks. Little human Heather had ripped herself open out of anger, but her passion was being met with equal fervor from human Ben. He pummeled her asshole with abandon, trusting that she could comfortably handle his giant werewolf dick.

"I'm close!" she shouted.

He was slamming her harder, faster. "Pressure," he groaned, "It's your cum in me. It's changing me!" Something cracked up his ass and thrust up suddenly, tenting his tender asshole. Her cum was disappearing into his body, and the big bad werewolf was growing up his ass.

"Fuck me!" Heather screamed. Her prostate was aching so sweetly, yes!

Another crack, and Ben bent over until he was practically lying on top of Heather's strong back. He cried out in pleasure and pain. His sphincter tented almost an entire inch and a half between his ruddy asscheeks, having been stretched out a bit when she buttfucked him. He reached around her body with his left hand and grabbed wildly at one of her breasts, pawing at a milking nipple. He reached below her with the right and found her massive cock, and he started giving her a reacharound--a first for both of them--while he flailed to push his dick in and out, in and out, buttfucking his girlfriend. "So much pressure," he said, and his asshole tented again. "It feels like I'm about to push a whole fucking wolf out of my asshole!"

"Cum!" Heather screamed as she was buttfucked silly and jerked off simultaneously. She squeezed her asscheeks and sphincter as tight as possible, making him work to pull out and push in, but he didn't slow down. His big wet cock was nearing the end.

"It's coming out of me!" Ben screamed, "My werewolf!" One final crack, his asshole starting to blossom as something emerged. "I'm cumming!"

Heather let out a squeal of pleasure as Ben's thick dick began pumping sperm deep in her ass. She orgasmed, jizzing all over her breasts and on his hands, and he roared. With a violent crack and a single buck of his hips, the start of a cum-slathered wolf's tail burst from his asshole.

She squeezed down with her sphincter again, tightening her cheeks. "Hatch!" she screamed.

He humped again, shouting, "I'm becoming a wolf!"

"Squeeze out your tail!" Heather yelled.

Every pulse of sperm equaled a pulse of tail growth, relentless. Half-squatting, tail-growing, dick buried into a flailing, quivering shewolf's ass--he pulsed, cumming in Heather's butt and squeezing a tail out of his own, while she jizzed in waves from her own cumming cock.

His tail grew rapidly, nearing its limit within seconds. He was forcing it with such strength, pushing it out of his human skin. Heather could hear the rumble of shifting tailbone over his cries of orgasm--a shared experience born deep in her butt.

With a final crack, his asshole ripped open and his skin split up his rump, and he blew an especially large surge of sperm into Heather's cummy behind while his tail rocketed out behind him and straightened. Cum overflowed from her butthole, slicking down the length of his massive dick, filling her furry crack with dripping spunk.

"Holy shit," Heather said, panting even as her werewolf's fur filled with sweat.

Ben pulled back, releasing inch after inch of sticky fat dick from his girl's asshole. When his cockhead popped out, she gaped, and with soft little gasps, she slowly closed her asshole tight over his massive load.

"Holy shit," Ben said.

"You only transform once," Heather said between breaths, "Try to enjoy it, right?"

"What happens next?" His half-erect penis was curved over like a banana.

Heather turned around and grabbed his hips. "Let me clean your dick." Without waiting for a signal, she darted forward and began lapping his cum off his monstrous cock.

"You're so fucking hot," Ben said.

She finished slathering her tongue over it once. Then she angled in the head and quickly pushed his dick down her throat.

"Ungh. You're making me stiff babe."

She sucked hard and pulled back, cleaning his broad cock from base to tip, until he finally unsheathed his throbbing footlong from her muzzle. Then she kissed the bottom of his cockhead.

Ben suddenly flexed, and his cock slammed to full erection while snapping off a little bit of leftover cum onto Heather's chest. His tail swatted the air as he flexed his arms, his muscles swelling, becoming brutally defined. He hunched over. His legs bent. Everything pulsed with sudden power, with instant male strength.

"Hatch!" Heather yelled.

She was his woman, and he would be a man worthy of her.

"My wolf!" she shouted.

His muscles were growing--he was growing all at once, from skinny to buff. There was a snap and he flexed even tighter. Brutally, the skin on his arms began to rip open over slabs of muscle, revealing spreads of soft grey fur. He then reversed, and instead of flexing he suddenly stretched them out. Violently, grey clawed hands punched out of his skin, shredding the hide on his arms like overfilled rubber. He stood, and his too-small human legs popped like stretched socks as grey clawed feet and powerful werewolf muscles tore their way out of his human skin

His chest barreled out in proportion. He bent over, tightening the skin across his broad, expanding back. His ass strengthened and rounded. Then he flexed, and in a single, meaty shred, his back split open, dividing his human skin all the way to the nape of his neck. Beneath was a field of thick grey wolf's fur, the beastly Ben. He flexed his pecs, dug into the skin like a man tearing away a tight cotton shirt, and pulled his skin in two from sternum to crotch.

"Yes!" Heather cried. "Hatch!"

His eyes closed. His face cracked with pressure and pleasure. He took a deep breath and howled as his skull changed inside his skin.

The final moment was here. His dick felt electric. Heather's tongue painted the length of his giant werewolf cock in saliva and warmth.

He grabbed the skin on his forehead, dug in like he'd found a hole in a rubber mask, and in one long brutal rip, he pulled his scalp and face into two lifeless pieces, peeling it away from a quaking, cracking grey werewolf's head, which burst into its final shape, muzzle erupting almost the instant his fur hit air, jutting forward into the final length of broad, gigantic male maw, filling with scything carnivorous teeth.

Ben threw aside the two halves of the little man that he'd been mere minutes ago; the giant grey werewolf, triumphantly standing tall with his penis erect, howled with a depth and volume that Heather had never managed, and his humongous cock, now suited to his muscular body, began to jet more hot ropes of cum than his giant testicles could've held. Arcs of cum rained down on Heather, hung from her face. Cum splattered on her gigantic milk-dripping breasts and dripped along the red pillar of her still erect crimson cock, flowing down to her balls.

Heather laughed with joy, admiring the handsome werewolf she'd coaxed out of her boyfriend--now her monstrous mate.

Before she could even praise him, he reached down and lifted her up and carried her over to the couch, easily handling her with his new found bulk, strength and height--lifted her up until she wrapped her arms around his neck and rested her head on his shoulder. Her cock flopped over her belly, still hard as steel. She looked up at him sweetly.

"Ben?" she asked.

He grinned, a toothy expression only suitable for werewolves. "You're mine," he said in a deeper, thicker voice.

She squealed with happiness when he set her down on the couch. She laid on her side and held her cock by the base so it would be angled out invitingly. Then he turned about and crawled onto the couch with his head facing the other end of the couch. Their huge horny cocks bobbed in front of one another's faces. It was time for a cock-sucking 69.

She stuffed her mouth instantly with his great grey prick. Salty-sweet cum flooded over her tongue. She grabbed him about his waist and held on tight, sliming his chest with a blend of his sticky sperm and her warm gushing milky tits. Her broad soft breasts were pressed against his rock solid pecs. Her nipples were rubbing over his soft fur, making her quiver.

He grabbed her huge cock a few inches down, then opened his mouth and started licking her prick clean with his broad, hot werewolf tongue. She moaned around his dick, and after a few seconds, he opened his mouth, slid her dick in several inches, and closed his lips around her hot veiny girth. Precum gushed out of her cockhead as he sucked hard and started giving his girlfriend her first blowjob. Then he began bobbing his head, lapping inside his mouth along the top of her glans. He knew how to please his own cock, and he knew she'd be sensitive there.

It worked. Heather moaned and quickly switched her own blowie to start rubbing his cock the same way. He grabbed her buttocks to give her support, and she let her thrust gently into his mouth. For nearly a minute, they sucked off one another in silence, bobbing their heads and moaning. They loved the big cock in their mouths. They were lovers.

Ben pulled back briefly to breathe, reaching out with a hand to gently cup her testicles while he spoke. "It was so hot when you ripped open your human pussy," Ben said, "I wanted your dick the moment I saw it."

Heather moaned and kept sucking his cock.

"I wanted the werewolf cock you were hiding inside your shaved pussy," he said.

Heather was gasping around his cock, already rising towards orgasm. Hadn't this been everything they'd led up to? This was the most pleasurable part, the consummation of their newfound bond.

"I wanted the werewolf," he said, his breath quickening.

He'd wanted the werewolf inside her shaved human pussy, up her tight human ass, behind the flawless mask of her face and beneath her hairless skin. He hadn't known it until he'd seen it, but he hadn't wanted a smooth doll, perfect and distant. He'd wanted a furry beast, aggressive and close, and she'd pulled back her skin to release it. They'd become werewolves together.

He put her cock back in his mouth, and to her intense surprise, he held his breath and started effortlessly deep-throating her dick. Of course he could--he became this beast to pleasure her. This companionship would be theirs to share for the rest of their werewolf lives.

The unspoken force that had changed them had made them mates.

Heather's werewolf cock pulsed in his throat. She felt like she was fit to burst one last time. Ben's cock pulsed in her mouth. She sucked hard, rolling her head back and forth to make his cock cum. Her breasts were smashing against him. His muscles felt tremendous and comforting against her.

Their cocks raised in pleasure, edging higher and higher as they sucked dick together. They were in love. They were going to cum.

With three more sucks from Heather's bobbing head, Ben felt his glans flare and his testicles tighten. He shivered and blasted a modest load right into Heather's eager mouth.

When she tasted his semen, Heather cummed down his throat and from her tits, making a mess between their chests; and she even came anally, her ass squeezing down on Ben's last load. Crying out in release, she squirted out a single jet of his cum from her werewolf asshole, splashing jizz on the floor. Ben held her by her ass and swallowed her entire load.

Then they pulled apart, cocks popping out of mouths with lines of thick saliva and cum, and Heather found herself unable to contain her happiness and relief. Slowly, sweetly, she began to howl, and Ben howled beside her.

Soon they relaxed and got up off the couch. It was done. Their cocks shrank to a manageable sizes when flaccid. Heather's breasts began to dry up, compacting, becoming easy to wield. Everything about them was still tremendous, but they'd be able to move.

Heather looked at the clock on the wall above the table and down at the floor, at the empty human skins that'd birthed two werewolves. "There's a few hours left before sunset. Think we should lock the door and wait until dark?"

"We'll wash our fur," he said thoughtfully, "and sleep. We'll need an early start."

"Why's that?" Heather hugged him. She loved him.

He pulled her close and stroked her fur. "Wolves are nocturnal, and the wilds are far away. We've got a long way to go."

They did have a long way, Heather knew, but she was satisfied. They'd meet the challenge now that the crisis was past. They hadn't broken up, and the tie between them was strong.
