Marianne knew the feeling had been building for a few days now. She and the creature had been meeting each other’s needs like clockwork for over two years, and their bodies were perfectly in sync.

It always started with a baseline horniness that was perhaps double or triple that of an average man’s sex drive. She found her head cloudy and distracted, and her eyes seemed to linger whenever she caught the beautiful sight of some other woman’s soft and supple breasts. That was one good part about being a tall, well-endowed blonde woman herself. If she was ever caught staring at a stranger, she could always play it off like she’d been admiring the other’s clothing. And she’d been admiring other women’s clothing all week.

Today would be the day. She had been trying to think of anything nonsexual all day long at work: car parts, boxes of cereal, quadratic equations and curving mathematical functions that suddenly morphed into long, fleshy tendrils, snaking and probing their way across her body-- Shit, it wasn’t working! She pulled her wandering hand out of her crotch and snuck a quick glance over each of her shoulders. Nobody in the office had seen her indiscretion. She licked the two wet fingers, savoring her own light feminine scent before swallowing the thin sticky secretion. So sweet, so slippery… so ready to breed.

She couldn’t take it anymore. She needed it inside her. Marianne adjusted her clothes, making sure the wet spot in her red panties couldn’t be seen through her black skirt, and hustled home as fast as she could. She only just barely managed to lock the door behind her as she rushed to her bedroom and knocked on the capsule that contained her lover.

Tap tap tap.

It had been waiting for her as well, and immediately the suitcase-sized chrysalis cracked open, one thin pink tentacle sliding out ahead of the rest. The creature had no eyes, but Marianne knew it could find her by scent, heat, and touch alone.

She laid on her back on the bed, still fully clothed, and waited patiently with her arms at her sides. In a moment she felt the first touch, like a single warm finger, on her heel, followed shortly by four or five more similarly slender appendages across the bottoms of both of her feet.

The creature’s probing arms were far more sensitive and delicate than any finger. And even though they’d repeated this tryst dozens of times by now, she could never keep count of how many prehensile little pleasure-legs it truly had. Most of the legs were uniformly round and featureless, with only a constant oozing of mucosal lubricant to let her know that it was something alien, rather than a small silicone imitation. But some of the animal’s tentacles truly lived up to the name-- and in fact at least two strong, muscular arms surpassed even the wildest definitions of that word.

It was these two sinewy tentacles that now gripped her ankles, stripping her socks off with ease. These two muscles could flatten out, broad enough to put any man’s hand to shame, and yet at the current moment they were condensed, tight, and compact. They snaked up her ankles, wrapping a long winding coil up until they each reached one of her knees. The one at her left knee immediately kissed her sensitive skin with the several suckers on one half of its surface, hard enough to leave behind a few hickeys for sure. The tentacle at her right knee, though it was a mirror image of the former, was far more gentle. It traced a slow circle in the crevice of her knee, just barely touching her flesh.

Marianne groaned and felt her legs involuntarily close shut at the unbearable sensation. “Stop tickling!” she moaned, feeling the forgiving rubbery texture of the creature’s body as she hugged it tightly between her ankles. “You know I just want you to get to the point already, you fucking tease!”

The creature’s entire body was far more inflatable than any cock could imagine to be. With a massive throb, it forced itself to twice its previous thickness, and ten times its hardness, with thick pulsing veins that criss-crossed just beneath its velvety skin. Suddenly Marianne’s legs were no longer in her own control.

The two strongest tentacles kept a firm grip on her knees, spreading slowly and deliberately against the gentle resistance that Marianne couldn’t help but provide. It felt so good to flex those thigh muscles, giving herself and the creature a delightful workout before the main event. She looked down and saw half a dozen thin fingerling probes sway back and forth in the air, perhaps savoring her scent before they dove in for their prize.

She was grasping the sheets with both hands now, waiting for the impending pleasure.

Suddenly the creature’s previously slow pace quickened. The several smaller tentacles darted into her crotch, easily tearing a hole in her panties and exposing the glistening lips of her sex to the slight cool breeze of her open window. She could swear the creature shuddered against her own trembling legs, and then it was on her like a hungry animal, sliding, slurping, licking its way up and down her outer labia to mix its warm lubrication with her own excited dribbles.

“Oh, fuck!” exclaimed Marianne, not caring if she could be heard halfway down the block. She tried to shift her hips to give the alien a better access to her blossoming cunt, grunting and straining and leaking a fresh squirt of her clear juices onto the soon-to-be-soaked bedsheets. Before she could make much of a motion, her entire body was lifted feetfirst halfway into the air.

Wet slurping sounds were all that she could hear now, flesh on serpentine flesh that sucked and pushed and pulled and prodded the outer folds of her pussy. She was being stretched and manhandled like a piece of tender meat, and she was enjoying every second of it. Each little round suction cup on the creature’s big tentacles was like a unique mouth, one after the other giving her clit a passionate kiss before sliding along to give the next circular muscle a chance to suck harder on her twitching little love button.

Her skin was on fire with sensitivity now, from head to toe, as the smaller tendrils of her lover’s body explored the further reaches of her skin. She felt five little wormlike extremities lace themselves between the fingers of her right hand, and she squeezed them back to show her appreciation. Her mouth was hanging halfway open, waiting for her lover to feed her the central heat of its desire.

She didn’t have to wait much longer. Her clit was swollen to near-bursting, and after one particularly deep gasp for breath, she felt the slap of a heavy tool against her cheek. The creature wouldn’t be ashamed to show off in a public shower, that’s for damn sure. It was hung longer than a horse, though it never seemed to be too thick for her to swallow. Right now it was still half soft, the spongy ridges of its cock sliding back and forth across Marianne’s lips to coat them with the sweet and salty slickness that was so intoxicating. She easily felt the first dribbles ooze out of the wide slit at the semi-hard tentacle’s tip with her tongue, and she let gravity carry the delightful slime down her throat.

There must have been some kind of hormones in that fluid, because her own pleasure suddenly increased. She pushed her hands down into the bed, lifting her hips higher and trying to bring the little magic fingers a little deeper into her pussy. They stayed put at her outer labia, though, leaving her so wound up with need that she cried out in frustration.

“Hraaaah!” she yelled, probably scaring away a nearby flock of birds. Immediately, giving her no chance to inhale again, the creature thrust its cock deep into her mouth. With a loud gag, she felt a rising contraction in her whole body, a mini-orgasm that slammed the headboard hard against the wall and forced a hot wet river of her girlcum to coat the main body of her lover. By now the lower half of the bed was practically a bath of clear body fluids, both human and alien, all thick and sticky with depraved desire.

She never really wondered how it was possible; she just went along with whatever the creature wanted of her. And once it plugged the entrance to her throat with that thick mushroom head at the end of its longest veiny tentacle, she didn’t have to breathe. It just somehow cleared up that need, and she could focus solely on the sensations of pleasure that she was receiving between her legs and between her lips.

Marianne swallowed hard, feeling the muscles of her throat do that oh-so-familiar cascade downward, taking her lover’s heavy tool deeper and deeper with every half-choked glug that echoed across the room. It had a strong grip on her knees and elbows, giving her the freedom to let her hands wander across the front of her own body. She found the skinny tentacles everywhere, snaking across her belly and swirling around her nipples, and her fingers traced their way up to her neck. This was her favorite part, feeling from the outside how full the creature could stuff her mouth. She felt the cock swell with a rhythmic pulse all the way from its base, through the tight ‘O’ of her lips, across her tongue, and then into the deeper recesses of her throat. Marianne knew that was a thick wad of the creature’s cum being deposited directly into her throat, and though she regretted not being able to taste it right now, knew that there would be plenty for savoring later.

The next phase was about to begin, and the excretions of her cunt were becoming an unstopping fountain now. Her inner labia were so slippery and swollen, they puffed out beyond her outer lips like a welcome mat for anyone to enter and breed. And that’s exactly what the creature intended to do.

The final and most specialized appendage of Marianne’s alien lover was its ovipositor. Not quite as ribbed as its penis, but even more prehensile and adaptable in shape. The tip had a much wider slit in it, and it had a gradual taper that meant the base was quite thick indeed. Now this tentacle designed strictly for reproduction found its way into the twitching entrance of Marianne’s pussy, sliding inch by inch into her and not even stopping when she suddenly reached another peak of pleasure.

She felt her pelvic muscles clamp down hard on the full length of the creature’s ovipositor, tightening and allowing it to thicken in response over and over and over as she squirted yet another burst of her wetness onto her own thighs. Simultaneously the alien’s cock thrust its way completely into her mouth, and didn’t stop until the thick head plunged directly through the sphincter that separated esophagus from stomach. Marianne’s orgasm wouldn’t stop cumming, and she felt jet after jet of cum travel at high velocity through the entire length of her lover’s cock to fill her belly. Nearly a half gallon of gooey white seed now stretched her upper body, making her diaphragm clench and relax repeatedly in an involuntary attempt to refuse this heavy flow. But it only served to drive her even crazier with lust, her eyes shut tight as she rode this peak of ecstasy. Her whole body began to adjust, ready to take everything the creature could offer her. She had its seed. Now she needed its eggs.

Before her climax could really begin to come down, she felt the first ovum begin to slide into position. By now all her constant orgasms had shifted her cervix down, and the muscled tip of her lover’s egglayer formed a perfect seal with it.

One by one, eggs just a little smaller than tennis balls moved up through the ovipositor, stretching her pussylips even further as they forced their way through her birth canal until they reached her cervix. They were forgiving and gelatinous, so with just a half-moment’s relaxation, the first one slipped through the centimeter-wide opening with a quick pop.

Marianne’s eyes flew open and she groaned, her tongue mumbling around on the underside of the cock that still plugged her throat and stomach. It wasn’t painful like this, though by all accounts such a thick object forced through her cervix should have hurt. Instead the sudden fullness of the night’s first egg made her reach that continual orgasmic state, in no small part fueled by the dizzying bellyful of cum that made her head spin with happiness.

Squeeeeze… pop! The second egg was inside, and it felt even better than the first. Marianne’s hands traveled down to her crotch, and her eyes fluttered shut again when she felt the third egg travel through the warm fleshy membrane of the ovipositor to disappear inside her pussy. Pop. And it was inside her womb with the other two.

Slowly, steadily, each new egg forcing the previous ones to stretch her uterus just a little bit more, Marianne was bred by the tentacle monster. Slurpopopop. Four, five, six now. Her throat spasmed again, milking another hot dribble of seed directly into her stomach where it churned and drugged her to new heights of hormonal pleasure.

Any outside observer might think the creature was digesting her for consumption, with nearly every inch of her skin coated with warm slippery precum-like mucus, and her abdomen beginning to stretch alarmingly full. But the truth was, every one of her needs was being cared for. Her body was saturated with oxygen, and the hydrating effects of the slippery lubricant prevented any permanent stretch marks or wrinkles on her body. In fact, her skin would be rejuvenated, blemish-free and springy like that of a bright-eyed eighteen-year-old.

Pop, slide, popsquishpopsquishpop. Meanwhile, the first dozen eggs had found their way into her womb, giving her the appearance of one who was eight months pregnant. Marianne’s breasts similarly expanded from the endocrine effects of the creature’s emissions, and they bounced back and forth like heavy milk-laden volleyballs. Her hands couldn’t help but wander across her artificially swollen mammaries, squeezing ever so gently. Beads of white milk immediately oozed from these glands, and the sensitive nipples nearly brought her to another cusp of her seemingly endless orgasm. When her pelvic muscles throbbed around the creature’s ovipositor, another half-dozen eggs suddenly slid in with the rest, stretching her uterus to its limit.

Though Marianne was in no state of mind to keep count, the creature knew that twenty-seven eggs was her personal best. She was holding twenty now, and her tentacled lover had no intentions of stopping until it had filled her beyond reasonable capacity. Of course, it was difficult to keep pushing eggs into her, because there was also over a gallon of masculine seed currently inside her belly that fought for abdominal space with the feminine eggs inside her womb.

Slurch, pop, slurrrrpoppoppop. Still she mumbled happily, her rosy lips making a suckling motion on the base of her lover’s cock. She kept at it until she coaxed two or three more thick ropes of cum into her stomach, and with a final shudder the creature pushed pop the last pop eggs pop into her overstuffed warmth. Twenty-nine.
