Anonymous 10/04/16(Fri)21:50 No. 5995 It took a long time for things to go back to anything resembling normality. The demon’s magic had been typically complex and the professors spent many days working to counter all of the magic she had spun. The simple magic that enhanced the student’s sexual appetites had been easily dispelled, leaving a room full of naked and thoroughly embarrassed young people, who covered themselves up and apologised to their numerous partners before dashing back to their rooms. Unfortunately, the more specific spells of the Succubus were much harder to dispel. The girl with the glasses had to be forcibly cut from the surrounding floor and spent three days hidden away in her room, unable to find anything large enough to conceal her breasts and with a large penis constantly at eye level. The pig-tailed girl required magical help to make her way back to her room where she remained, topless, for a similar time until the wizards managed to revert the magic. She did however spend a lot of that time in the company of her boyfriend who seemed rather fond of her new attributes, however extreme they may have been. Susan had an easier time, her magical underwear being removed after a few exhausting hours, although she was the subject of much speculation after the item disappeared mysteriously. The twin-girls grew very close indeed during the nine days it took to reverse the magic merging their bodies together and have since spent much time in each other’s private company. The most complex and controversial problem raised from the event was of the transformation of the young man into a large, black demon, and his partner’s insatiable lust for his gargantuan penis. The girl was inconsolable when separated from her cohort, and countering the magic that caused this proved troublesome. It was decided – after much disagreement – that the two would be kept together in quarantine, hidden away in a hospital room until their maladies could be addressed. After two weeks of the pair’s near constant sexual escapades (and regular cleanings of the beast’s quarts of gushing semen) the magic was reversed, and the pair bid each other a very embarrassed farewell and proceeded to avoid the other’s company whenever possible.

After everything seemed back to normal, all students were given a health and safety lecture regarding improper storage of runes and sigils and everything seemingly went back to normal. However, unknown to the staff, not all of that day’s magic had been undone. A blonde-haired girl had her deepest fantasy made reality by the errant demon, and was not about to relinquish that gift. The girl named Lydia seemed quite ordinary to the casual observer, but she had deep, domineering fantasies, the idea of absolute control made her quiver. Courtesy of the Succubus, Lydia had been granted a powerful magical relic, granting her massive, temporary control over matter, time, even peoples’ actions and feelings, the kind of artifact that desperate fools would sell their souls for. Lydia sat on the edge of her bed, her hands shaking slightly as she examined the item in her hands. The relic was made of some dark, red-black, glassy material and comprised of a pebble like mass the size of a human palm and five hoops spaced to fit over the thumb and fingers. Slowly, Lydia slid her fingers into the holes and uttered a quiet gasp as the rock connected with her palm and sent a shiver of power through her body. She made a fist around the device and smiled slyly.

Lydia was sat in the dining hall, on a relatively empty table looking over all the other students there to find a test subject. Her mind was flooded with ideas of the things she could do with her new powers, she just needed to get herself started. She spotted a couple she didn’t recognise, a girl tucking into a sandwich and her boyfriend, laughing at some joke she made - as good a target as any. Lydia opened her palm underneath the table and planned for maximum impact, most importantly, ensuring nobody would intervene. Without a glow or a flash or a poof of smoke, the glassy orb did its work, and though there were no obvious changes to the other students Lydia could feel the magic had worked. With the stage set, Lydia prepared her stars. She watched in delight as the girl abruptly began removing her clothing, taking off her top and wriggling out of her skirt with a confused and bewildered look on her face but unfaltering actions. It was not long before most of the people in the room were watching the surreal spectacle, and the girl pulled off her bra and panties, kicking off her shoes nonchalantly with a look of humiliated horror on her face. Neither she nor her boyfriend spoke a word, though the other students were muttering to each other intently. Once she was entirely naked and her face flushed bright red, the girl pushed all the food and utensils off the table in front of her, clearing a space. She climbed up on the table and crouched down on all fours, her naked bottom poking up in the air and her breasts pressed against the table surface. Once she was in position, Lydia transformed the boyfriend into the first animal that came to mind, a tiger. There was no spark or flourish, just a tiger sat on his hind legs where the boyfriend once sat. The appearance of a large tiger did not panic the other students thanks to Lydia’s relic, they simply watched as the beast hopped up onto the table and straddled the girl, who remained still and quiet, despite the fear obvious in her upturned face. The girl’s arms grasped the tiger’s front legs and her bottom poked up towards the crotch of the beast, which was sporting a large, thick erection, at least nine inches long. As she wiggled her backside in the air, her former boyfriend in his bestial state manoeuvred his swollen cock into position, and with a quiet growl thrust the thick tiger-cock into her arse. The girl let out a faint cry as the enormous phallus pumped in and out of her virgin hole, and the surrounding students began to giggle and laugh as if watching someone fall over comically, their reactions’ distorted by Lydia’s magic. Tears began to well in the girl’s eyes in humiliation over her virginity being taken in such a public manner, a private moment ruined not only by the staring, laughing faces of so many people, but by the fact she was losing it to a tiger. The pleasure she felt at being stretched so wide by the bloated tiger-cock only heightened her unhappiness, she felt dirty at enjoying such a perverse occurrence, even a little.

Lydia smiled at the spectacle, pleased with the outcome and the extent of her newfound power, but ultimately bored. She stood up and left the dining room, catching one last glimpse of the poor girl’s face as the tiger ploughed deep into her tight little pussy.

Lydia strolled through the halls, experimenting with her power in various ways, making herself invisible and even allowing her to walk through solid objects. She wandered through the halls of residence, through the personal rooms of the students there. Many of the rooms were empty, but that didn’t stop Lydia from amusing herself; she pettily stole money, broke furniture and otherwise caused havoc where she walked.

As she entered one room, she saw a blonde girl laying on her front, on her bed reading. Without letting the girl know she was there, Lydia restrained her arms and legs, magically preventing her from moving from the bed. Her victim unable to struggle, Lydia – retaining her invisibility – grasped the girl’s skirt and unhurriedly began to raise it up over her buttocks. As soon as she felt the movement of her skirt, the girl’s head shot back, but all she could see was her skirt moving of it’s own accord. “Who’s there!? Who’s doing that?!” she yelped, realising she was unable to move her arms or legs. “Oh God…” she whispered to herself in dread as her mind raced to find a way out of the situation.

Lydia had the girl’s skirt rolled up fully around her waist, and moved to tug down her panties as the girl cursed and struggled in vain. With her panties around her ankles, Lydia gestured faintly in the air and conjured a pale yellow, complex looking dildo. The girl turned her head and shouted “Shit! Please, don’t do this, please!” as she saw the impressively large phallus, at least 9 inches in length. Lydia paid her no heed, and began stroking the dildo playfully around the girl’s groin, rubbing against her exposed slit as she spluttered objections. Lydia soon grew bored with taunting the girl, and placed the tip of the dildo on her anus, producing a loud scream of “Fuck! No, please not that! Not there!” which trailed off into moans and grunting as she slowly but steadily pushed all nine inches of the bumped dildo up into the blonde girl’s rectum. Before she left, Lydia pressed a tiny button on the base of the dildo, causing the dildo to vibrate and oscillate inside the blonde girl, who moaned and whimpered even louder, unable to do anything to stop the torment, trapped in her current state on her bed. Lydia left the girl’s room through the wall, wondering with amusement how long she would stay trapped that way before someone found her. Perhaps Lydia would go back and see later on.

On her way to the staff offices to see what fun she could have there, Lydia passed through a few more students’ rooms, and cancelled her plan when she wandered in on an unexpected and unusual sight. As she passed through the wall of one room into the next, she had stumbled across two girls, both naked, mid-conversation, who referred to each other as Hermione and Susan.

Lydia surveyed the scene with an incredulous smirk, the girl named Hermione was knelt on the ground, wearing a faux bunny-suit; two long, floppy ears attached to a head-band and a fluffy bobtail. In a rather jarring contrast to the rest of her costume, she also had a strap-on dildo attached to her face, a long phallus protruding from her mouth, muffling her words as she spoke. The other girl, who looked faintly familiar to Lydia, was stood in front of Hermione, wearing a strap-on attached to her crotch.

“Well, this was unexpected,” Lydia spoke.

The two girls’ heads turned suddenly to stare at the now visible Lydia, Hermione’s strap-on wobbling to and fro as her head shifted. “Is she with you?” Susan asked, crossing her arms over her chest. Hermione shook her head and mumbled, “Nope, not one of mine”. Susan raised a hand, preparing to cast a spell that would remove her from the room only to find her magic, not failing, but simply not happening.

“Just what the hell is going on here?” she spat at Lydia as Hermione discovered her own magic was not occurring. “Oops! No magic? Sorry girls, but I’m in charge now, “ Lydia replied with a smirk. “Don’t worry though, there’s no reason for you two to stop your little… game. In fact, why don’t we make things a little more realistic?”

Susan gasped with horror as she felt her body altering, that all too familiar warping sensation rushing over her with a new and terrifying extremity she had not experienced in any of her previous transformations. It did not take long; she felt the dildo strapped to her crotch begin to change and meld itself to her body and could see her breasts rapidly flatten, her whole body changing shape, even her hair shortening. In a few moments Susan had been totally transformed into a male mirror of her former self, albeit a somewhat feminine version. Her face remained almost the same, though her features were harsher and sharper, her hair was cropped to shoulder length, giving her a rather androgynous appearance. Her figure was still lithe and faintly muscled, but her hips were narrower and her hourglass figure had become more solid, her chest no longer sported a pair of perky breasts and a hard cock and balls jutted out from her crotch. She gazed down at her new body, mouth open, face contorted into an expression of shocked dread. She had felt the power of this girl and realised that she and Hermione were dealing with something far beyond their control.

Meanwhile, Hermione’s transformation had been just as distressing and infinitely more peculiar. She tried her best to remain calm as she felt the bunny-costume merge with her, the two floppy ears poking up from under her hair no longer attached to a headband and the bobtail fully joined with her coccyx, twitching a little as the magic spread through her. Harder to withstand was the worry caused as she felt the phallus on her face fuse with her tongue. The straps holding it to her head vanished and the body of the dildo merged entirely with her tongue and became real: Hermione’s tongue had been replaced with a fully erect penis that poked out several inches from between her plump lips.

“Oh man, you guys are going to be fun,” Lydia enthused, looking at her new creations, “I bet I can think of all sorts of things to do with you two.” She watched the expressions of the two girls, shocked, horrified and utterly defeated and tried to think up some obscene games to play with them. “You know what always helps me think? A good smoke. You, Hermione right?” she asked with a smile, looking down at the girl who still knelt on the floor, “why don’t you go down to the campus shop and grab me some cigarettes?” Lydia’s mind moved fast, “There’s a bike just outside you can ride down there. Only, make sure to ride it properly or I will be very, very upset,” she finished with a wry smile.

Hermione stood shakily, her own mind racing as she left the room. Still naked, she crept carefully through the halls, her heart pounding, every noise making her jump with the fear that somebody would open their door and find her there, naked and transformed so horribly. Her penis still protruded hard from her mouth, though she tried her best to conceal it, the head and at least two inches still poked out from between her lips. Like Susan, Hermione had realised the intensity of Lydia’s magic, and realised the only hope she had of being returned to normal was for Lydia to will it, so she would have to do as she was told in the hope that she would return the two of them to normal. Obviously though, she intended to do so while causing the least amount of humiliation to herself. The idea of walking into a busy shop, naked except for a pair of rabbit ears and a firm erection poking out of her mouth was sickening but right now, Hermione could see no alternative. Her first plan was to get to the bike Lydia had talked about – her bike – there was a raincoat stored in the side-pack for emergencies, at the very least she could cover up her nakedness, one less problem to worry about. Hermione approached the back door of the building cautiously, if she could make it out of here without being spotted it would not be far to the bike rack and from there, to her raincoat. She peeked out the window, her pulse racing, at once terrified of dashing out and being seen and of being caught inside the building. She couldn’t quite see anyone outside, though her view was partially blocked by the positioning of the window. The constant noise of day-to-day life inside the building had her pulse racing, worrying that at any moment someone would come out and catch her, so Hermione took the risk, lowered her head, opened the door and ran to the bike rack. She could feel the breeze blowing around her naked body, a constant reminder of her vulnerability, and she felt her heart in her throat as she fumbled with the zip on the bike’s pack, frightened to look around for fear she would come face to face with a group of staring strangers, revealing her face and the penis sprouting from her lips. She fumblingly pulled on the raincoat and did up the buttons, her head still lowered to allow her hair to shield her face. The raincoat was unfortunately short, and only reached midway down her thighs, probably enough to convince someone not looking too closely that she wasn’t naked, but a stiff breeze or misplaced glance could easily expose her as being utterly nude. The next step of Hermione’s plan was to quickly ride the bike somewhere secluded to give her more time to think, and to make sure that if there was anyone currently watching her, they wouldn’t have enough time to recognise her. When she went to do this though, she understood Lydia’s final words. The seat of her bike now sported two long, thick dildos, positioned to allow – or in this case, force – the rider to insert them into her pussy and arse. Hermione’s plan momentarily shattered, she wheeled the bike by hand around the corner of the building in a state of panic. With one arm faintly covering her mouth, she glanced up and around, seeing no one in the vicinity and began to calm herself down. To add to her already considerable distress, Hermione heard voices coming from behind the wall in front of her, at least three loud, boisterous male voices, coming right towards her. She could tell from their voices that these boys were not the type to walk idly by while a girl wearing a skimpy raincoat stood hiding her face and she couldn’t bear the idea of wheeling her bike back the other way, potentially walking face first into those who might have only seen her from behind. Hermione could think of no other way out of the situation than cycling as fast as she could manage past the boys heading her way, covering her face as best as possible and praying they didn’t pay her any attention. Unable to think of any other solution to her problem, Hermione surveyed the bike seat: the two dildos were flesh coloured and of different sizes, the front one resembling an ordinary penis, six inches in length, but the rear one thinner and longer, closer to nine inches and covered in small bumps down the whole length. Thankfully, both dildos were covered in a layer of some sort of lubricant. Hermione straddled the bike frame, both feet on the pedals, one hand on the handle and the other propping her up against the nearby wall. She wiggled her bottom to allow the base of her raincoat to ride up just enough, exposing her bare backside, peering down between her legs, she hurriedly tried to line up her anus with the taller dildo, but found herself unable to see closely enough without losing her balance on the bike. As the laughing voices grew closer, she pushed her bottom down, feeling the tip of the larger dildo poking her and manoeuvring it to her anus. With little time to spare, she braced herself and pushed down, forcing the slippery penis past her sphincter and up into her rectum. As she slid down closer to the bike seat, Hermione let out a faint moan - muffled further by the cock in her mouth – as the bumpy dildo violated her, pushing deeper and deeper up inside her bottom. Next, she positioned her pussy lips over the second dildo and pushed herself down further letting out a gasp and squeal of discomfort at the twin penetration. Hermione was used to vaginal penetration, but still found the sensation of anal sex unpleasant: the stretching of her tight little anus and the peculiar feeling of a large intruder in her rectum, regardless, she was running out of time and forcibly thrust her bottom down on the seat, impaling herself fully on the two cocks. Her eyes bulged and she clenched her lips tightly around her penis-tongue to stop herself shouting out as the long dildo plunged deep inside her clenched bottom, but Hermione could not afford to waste any time becoming used to it. She tugged her raincoat as far down as she could manage, unsure of how much was visible, lowered her head so her hair would block any side view of her mouth and raised one arm to cover the front of her face. Staring up, she planned her route and quickly cycled forwards.

Meanwhile, Susan and Lydia were sat in the room, watching Hermione’s actions via a magical creation of Lydia’s. “Y’know, I think the coat thing is cheating a little bit, but I guess I can let her off. I wasn’t specific about her having to be naked, right?”

Lydia smiled confidently at the naked Susan, “I guess I can even the score later on anyway.” The image of Hermione vanished in a flash and Lydia turned her attentions to the male Susan, “While she’s busy there, how about you and me have some fun, hmm? Stand up.” Susan stood up, whether through her own fear at disobeying or through a magical command she was not sure. Lydia circled “her”, admiring Susan’s body before stopping behind the quivering former-girl. With a smirk, she conjured a small, pink butt-plug in one hand while rubbing her other hand on Susan’s backside. Susan let out a soft moan as Lydia slipped her finger up her arse, and wiggled her bottom involuntarily as she felt Lydia spreading a cool, slippery lubricant inside her. Lydia pulled her finger out teasingly and rubbed a spot of the lubricant on Susan’s anus slowly, without a pause she then thrust the butt plug all the way inside Susan, who cried out in surprise. Lydia playfully pushed at the base of the butt plug, amusing herself with the reaction that Susan gave as the small device quivered in her bottom. “So Susan, I’ve got this idea for a great game, I think you’re going to absolutely love it,” Lydia whispered seductively into Susan’s ear, one hand still playing with the butt plug, while the other stroked Susan’s cock gently, her breasts pushed hard up against Susan’s naked back. “The only way for you and your girlfriend to turn back to your normal is if you come inside her tight little body. Obviously, there’s a catch. I’m going to make this pretty little dick of yours grow all big and fat. It’s going to get bigger and bigger and bigger every second and it’s not going to stop, and if it gets so big that you can’t force it into any of pretty little Hermione’s holes, you’re both fucked.” On the last word, Lydia thrust her palm on the base of the butt plug, and Susan cried out in her somewhat deeper voice. “There is… one way to stop it getting bigger of course. If you start wanking that little dick of yours it’ll stop growing for the moment, ‘cept it’ll switch things around. Instead of your cock getting fatter and fatter, that cute little toy in your arse is going to get fatter and fatter. So if you’re feeling selfish you can let that dick of yours grow up all big and strong and ream pretty little Hermione good and hard, or maybe you’ll prefer to be a good boyfriend and let that tiny butt plug stretch your sexy bum all out of shape.” Lydia circled around to Susan’s front, her hand running across her smooth, male body, “I told you it was a fun game. Now let’s play.” Susan let out a silent gasp at the sensation of Lydia’s magic at work and stared down at her slowly expanding penis. She could feel the flesh swelling, as if it was filling up with thick liquid, it happened slowly, just barely enough to be visible, but Susan could tell it would grow impossibly vast before Hermione returned. Susan realised the seriousness of her situation – if everything Lydia had said was true – and accepted that she would have to do everything she could to slow down the growth of her cock, if she couldn’t fit it inside Hermione they’d both be stuck like this, and that would be much worse than a little anal stretching. Gingerly, unsure of quite how to go about it, Susan began to masturbate. Clutching her hard dick in one hand, she started rubbing up and down, biting her lip at the unusual feelings of pleasure and closing her eyes. As promised, her cock ceased its growth and she felt the butt plug inside her expanding, the smooth plastic device stretching her insides slowly but surely was rather pleasurable, even more so in Susan’s new, male form. The speed at which it grew did not feel too excessive, Susan grew hopeful, imagining she could last for quite some time, and becoming increasingly aroused by her actions. Lydia sat on the bed, watching the male Susan masturbate, with a smile, knowing that eventually the size of the butt plug would become too much for her to manage. She recreated the image of Hermione who was cycling down a secluded forest path, and spoke to her, “You heard all that Hermione, so you know the score. The faster you get back here with my cigarettes, the less likely your cunt is to be ripped apart by your boyfriend’s massive cock. I was less than happy with your raincoat trick by the way, so I’ve made a little addition to your bicycle. Enjoy!”

Hermione had taken an alternate route to the campus shop, a quiet and often unused wooded path. Her cock still poked out from between her lips and she moaned every time she cycled over a lump in the path as the two dildos buried deep inside her jolted and jiggled. She had been cycling slowly to try and lessen the discomfort and give her time to think, but now she knew the situation of Susan’s expanding cock she felt a sense of urgency. To her growing distress, Hermione felt the effects of Lydia’s “addition” to her bicycle: as she peddled, the two dildos inside her began to pump rhythmically. Perfectly synchronised with her speed, the dildos thrust in and out of her - as one pushed up into her the other withdrew. “Oh shitttt,” Hermione cursed quietly to herself, her hips gyrating as the two dildos plunged into her. Even worse was that as she cycled faster the dildos pumped faster, creating an almost unbearable level of constant stimulation from her pussy, and of constant uneasiness from her deeply filled anus. She gasped and moaned as she began to peddle faster and faster, having trouble focussing on the road at all. Hermione accidentally steered the bike over a large pothole, jarring the whole frame of the bicycle and making her cry out loud at the sudden thrust. Faster still she rode, her mind numb with the sensation of it all, until Hermione realised her plan was working: she felt something building up deep inside her body, and suddenly she threw back her head as an orgasm rocked her body and her tongue-cock spewed forth a gout of semen, dripping down the front of her raincoat and dribbling down her chin. “No time to slow down,” she thought, “got to clean up and stay focussed.” The twin dildos continued their fucking as she rode, and her pussy juices were dripping down her thighs and all over the bicycle seat. Cautiously, taking one hand off the handles, she wiped as much of the cum off her raincoat as possible, then from her cheek, before slipping it under the coat and wiping the excess off on her belly – there was nowhere else for her to dispose of the sticky liquid that people wouldn’t see. She smiled to herself, proud as she realised her plan had worked, the cock in her mouth was growing flaccid, and when she pulled her tongue back as far as possible, she could fit the entirety of it inside her mouth. Now she could cycle to the campus shop as fast as possible, buy some cigarettes and rush back to her room without fear of anyone knowing her tongue had been replaced with a penis. The worryingly short raincoat and twin dildos were a problem, but nothing she couldn’t deal with. With renewed vigour, Hermione peddled onwards to the campus shop, trying to keep her face composed as she took a detour onto a shorter but more frequented path, sweating not with the effort of cycling, but with the thrusting stimulation of those two dildos. Relief was in sight, as she approached the campus shop. Hermione rode her bike around to the back of the shop, so she could dismount and hopefully keep the bike hidden from prying eyes. “Okay, getting off, this is going to be rough,” Hermione thought as she slowed down. Approaching the back wall of the shop, she propped herself against it, glanced around to make sure she was alone and slowly raised herself off the seat. She moaned softly as the two dildos slipped out of her slick holes, the vaginal one first, and the one in her arse after a few more inches, the feeling starting to turn her on. Both her holes were stretched open and gaping slightly and her juices were still running down her inner thigh, though she tried her best to wipe them away the constant stimulation had made her very wet indeed. Hermione was starting to get aroused by the thought of her slick pussy and the feeling of those two dildos as she had slid off them; she could feel her tongue growing firm and tried her best to keep a cool-head. Pulling down her raincoat to cover as much of her thighs as possible in an attempt to look half way decent, she dashed inside the shop. “No queue, thank God,” she thought her tongue still stirring. Hermione walked to the counter, picked up a box of cigarettes of no particular brand from the front and placing them down in front of the cashier, a short redheaded girl, wordlessly. “Will that be all?” the redhead asked. Hermione nodded silently, feeling around in her pocket for some change and trying to ignore the wetness she could feel trickling down her inner thigh. “I like your ears,” the redhead spoke, smiling friendlily and gesturing at Hermione’s bunny ears. “She must think I’m trying to be cute or something,” Hermione thought while she smiled back at the girl, hoping desperately she wouldn’t ask any more questions. As the cashier rang up the cigarettes, Hermione overheard two voices talking quietly in the queue that had formed behind her. She could only make out a few words, but knew they were talking about her. Phrases like “I don’t think she’s wearing any panties” and “…bunny-tail…” along with hushed laughter made her blush crimson. It didn’t stop her tongue cock from growing still harder though and she could feel it beginning to bulge and press against her lips as she counted the change from her pocket. She dropped the coins on the counter surface, grabbed the cigarettes and strode swiftly out of the shop back to her bike. Hermione struggled once more to impale herself on the two dildos as her tongue-cock began to poke out from between her lips. She began forcibly masturbating with her right hand in an attempt to speed up the climax and softening as before, all the while planning stoically her trip back to her room.

Meanwhile, Susan was still stroking her own penis, gasping and panting, her eyes closed and her jaw clenched. Lydia sat on Hermione’s bed, one hand down her pants as she watched the spectacle with increasing arousal. Susan had been masturbating solidly for the whole time, and the plug in her rectum had grown hugely in relation to its initial size. She could feel its immenseness stretching her anus, a feeling she was somewhat used to when in control. Now though, with the toy growing faster than her anus could adapt to, she needed to slow things down a spot and took her hand away from her penis. Instantly, the toy stopped its growth but she could already feel her cock swelling. “Too big for you sweety?” Lydia asked, removing her hand from her pants, fingers glistening, and standing up. Susan was standing perfectly still, trying her best not to do anything that might make her tender anus clench down on the large intruder, “Just… need some time to get used to it,” Susan replied.

Lydia stared at her swelling cock, slowly taunting Susan as it grew, “Well I hope you don’t take too long or you’ll end up hung like a horse. I wonder if Hermione can fuck a horse? You had better hope so or you’re going to be stuck in the stable forever.” Sauntering over to Susan, Lydia bit her lip hungrily. ”Gosh, just look at this beautiful thing,” she said caressing Susan’s cock with one teasing hand, “all hard but with nowhere to go.” With that, she took the head of the penis in her mouth, dragging a groan from Susan’s chest. Lydia lapped the tip of the still enlarging penis, slowly but surely taking more and more of it in her mouth as Susan gasped and clenched her fists, completely at the mercy of Lydia’s expert touch. She continued to suck and lick the penis as it grew larger and larger, until Susan could feel a climax boiling deep within her. She let out a great moan as her whole body clenched, including her tight anus around the large anal plug as she felt an orgasm ready to rip through her body, and then… nothing. All those wonderful sensations had stopped abruptly and Lydia had removed her engorged penis from her mouth. “Not yet sweet-thing, I’m not done,” Lydia spoke, smiling, “I want this hot little number inside me. I want to feel you swelling and stretching me out from within, so no cumming for you just yet. I hope that doesn’t make you too horny.” Lydia grinned wide at the clearly frustrated Susan as she slipped out of her trousers and panties, taking Susan’s now seven-inch cock in her hand as she bent over, displaying her pert, round buttocks to the horny boy-girl and whispered, “Fuck me.”

The denial of her climax had left Susan with an astonishing amount of sexual energy, and she ignored everything she knew was wise and right and drove her bloated cock into Lydia’s wet, inviting pussy, making the girl grunt. With her masculine hands grasping Lydia’s peach-like buttocks, Susan thrust all the way into her, pulling the girl’s backside all the way down onto her shaft. “Oh God, you’re big!” Lydia gasped, leaning back and rubbing her back against Susan’s flat chest. “Hold it there a moment.” Lydia used her magic to hold Susan’s movement, preventing her from pumping in and out of the girl’s slick entrance. “Oh wow… that’s such a… I can feel you getting bigger and bigger inside me Susan.” Lydia giggled and ground her hips against the immobile Susan. “It’s glorious… I want you to screw me with that big thing until I’m cumming all over the floor Susan!” and so, freed of her binds and teased further by Lydia’s game, Susan did so, pumping her growing cock in and out of the slippery hot girl, lost in the untold pleasure as both Lydia and Susan shouted and moaned in the throes of ecstasy. As Susan felt herself about to reach orgasm again, Lydia spoke: “Bad boy! You’re *pant* supposed to satisfy your woman first!” and Susan’s climax was cut short again. Growing hornier still, Susan fucked Lydia harder and rougher, her frustration growing, but Lydia seemed to enjoy it even more, shouting louder as her tight hole was stretched further with every moment. Soon, Lydia peaked, her pussy squeezed down hard on Susan’s cock and she quivered, her juices running heavily down Susan’s shaft. Susan carried on pumping, still desperate to reach climax, but Lydia slid off her cock and stepped away, preventing Susan from moving her feet. “Please! Let me cum!” Susan shouted, masturbating once more, her anal-plug swelling again. “Where’s the fun in that?” Lydia replied, “No, I’ve got a better idea, we’ll switch the rules! Instead of your butt-plug growing when you wank yourself off, your cock will. The more you tug, the bigger you get. All that time you spent making your bum all stretched and red for your girlfriend’s sake was sweet, but do you have the willpower to stop jerking off after all that teasing? Let’s see.”

“I’m s...s...sorry,” Susan whimpered as she continued to masturbate wildly, clutching her cock in both hands, desperate to ejaculate.

Lydia sat back on the bed satisfied, still naked from the waist down, her juices running down her thighs. She watched with amusement as Susan stood masturbating, regret on her face as her dick grew still larger, yet unable to control her throbbing sexual desire. Over the next few minutes, Susan’s hands grew gradually fuller as the meat clenched between them grew up to an ungodly eleven inches long, with a proportionate width. Susan looked down at her cock with dread, knowing that Hermione would have to take it inside her if they ever hoped to be normal again, and a resolve washed over her. Against all her instincts, she let go of her grasp and ceased masturbating, feeling the familiar throb of the now swelling butt-plug once more. Lydia smiled and spoke tauntingly, “Too little too late dearest. There’s no way Hermione can take that entire thing inside her. Did I mention that you need to stuff that entire massive thing inside her? The only way your cock is going to spit cum is if the entire length is buried deep in pretty Hermione. And no cum means no reversal.” Lydia shook her head in mock regret, “Nope, that’s far too big for a little thing like her, you should just give up. There’s no need to rip apart your cute bottom now, you should just carry on wanking, why not see how huge you can get that thing?” Susan ignored Lydia’s mocking words and focussed on coping with the now enormous dildo in her rectum, it must have been at least three, maybe even four inches in diameter. That was nothing compared to what Hermione would have to deal with though, maybe the girl was right, would it be too big? Hermione had taken Amy’s huge cock so long ago, but that was with magical assistance, how would she cope with this monster? Susan clenched her fists with frustration, with hormones rushing through her body she had a hard time controlling herself, she was desperate to take her massive dick in both hands and just pump away regardless of the knowledge that there would be no relief. At that moment, Hermione burst through the door, panting from exertion, her flaccid tongue-cock lolling absurdly from her mouth. Hermione stared at Susan’s bloated penis with a look of dread, mixed with pity at Susan’s obvious distress – both from her unimaginable horniness and the gradual stretching of her anus. “Let’s finish this,” Hermione spoke matter-of-factly as she took off her raincoat and approached Susan’s swollen member. Lydia perched on the edge of Hermione’s bed, watching with a large grin. “This is going to be great,” she chuckled as Hermione approached her task dutifully.

Hermione stood naked before Susan, who whimpered as Hermione grasped “his” swollen cock in one hand, turned around and bent over. Susan’s lust raged as Hermione’s pert buttocks bobbed in front of her, her bunny-tail twitching adorably as the girl guided Susan’s cock to the entrance of her slick, somewhat stretched pussy. “I’m sorry Hermy, I tried to stop but it was so hard and she kept changing the rules and it’s too big and I’m sorry Hermy, I’m sorry…” Susan whimpered softly.

“It’s not your fault Susan. Now come on, we have to do this.” Hermione spoke softly and confidently and pushed her hips back onto Susan, feeling the engorged head of that huge column enter her. She grunted and clenched her jaw as the enormous member pushed steadily inside her, stretching her slick vagina wider and wider with every inch. “Shit,” Hermione swore, “so… big. I think it’s still growing Susan, I can feel it…” she let out a loud moan as she forced her hips back further, squeezing yet more of the gargantuan log into her. Out of idle curiosity, she placed one hand on her stomach, and sure enough she could feel the outline of the hard rod of Susan’s cock through her taut belly, a truly unusual experience. Susan did her best to restrain herself, she too could feel her cock growing again, and this combined with the wonderful tightness of Hermione’s vagina was making it hard for her to stop herself from simply grasping Hermione by the sides and plunging herself all the way inside the lithe girl. Hermione grunted out loud as felt Susan bump against her cervix. Reaching behind her, she grasped Susan’s cock (eliciting a deep groan and restrained attempted thrust), she could feel four inches still not buried in her and watched Lydia giggle as she said, “There’s too much for me Susan, I just… can’t take any more of you.” She hurriedly leant forwards, pushing her hips out and Susan’s cock slid from inside her. Susan swore loudly at the wonderful sensation, her hands clasped around the base of her shaft, pumping without regard. Hermione grunted again as the tip of Susan’s cock slipped out of her, her pussy was stretched wide open, wide and dripping and very sore. “Quickly Susan,” she gasped, “my arse: stick it up my bottom!”

“Holy crap!” Lydia exclaimed, clapping her hands a little, “that’s damn brave of you girl!” Hermione panted wordlessly as she bent over again and parted her buttocks. “We need to get this done before Susan’s cock gets even bigger,” she thought looking back at the penis that had now grown to almost thirteen inches. “It’s going to hurt like hell, but I’ve got to get it done before it’s too late.” She stretched her anus as far as she could manage with her two index fingers – thankfully it was still well lubricated from the bike-seat – removed the fingers and slowly forced the still slippery head of the loudly moaning Susan’s cock past her sphincter. Whimpering loudly at the intrusion, Hermione realised she wouldn’t be able to push this all the way into her fast enough – the pain and discomfort was slowing her down and at the current rate it was expanding it could be twice as big before she managed it all. Her only hope was to goad Susan into doing the hard work, forcing it into her without any regard. “Fuck Susan, your big cock feels so good inside my tight little bottom. Look at how wide my poor little arse is spread, can you feel how tight it is, clenching down on your big horse cock? Don’cha just want to ram that big thing all the way inside me? Think how good it’ll feel Susie. Fuck me Susan, fuck me hard, I want all of you inside me now.” Whether she had understood Hermione’s plan or if she had simply been tipped over the edge of lust by her porn-star speech, Susan didn’t hold back. She grasped Hermione’s buttocks roughly and forced her hips forwards, inch after inch of her slippery swollen meat being enveloped by Hermione’s rectum. Hermione gave a guttural cry as Susan plunged deeper and deeper, every moment filling her with another inch of that enormously thick, hot cock. “God YES!” Susan bellowed as she thrust Hermione’s small backside all the way down to her pelvis, filling the tight girl with the remainder of her gigantic dick. With the entirety of her penis inside Hermione, Susan began to fuck the girl’s arse with relish, driving her hips hard, thrusting and pumping, drawing out all but a few inches before plunging all the way back into her again. Hermione‘s cock-tongue had grown hard again, and gave an almost amusing impression that Susan’s cock had grown so long it was poking out of the girl’s mouth. Hermione continued to grunt and groan loudly, her own penis bouncing with each thrust of Susan’s. After a few brief moments, Susan pulled Hermione back down all the way onto her with such force she fell backwards onto the floor the final thrust causing both Susan and (to her surprise) Hermione to climax. Susan screamed out loud and incoherent as she finally reached orgasm, a twisted image of ecstasy on her face. Hermione felt the rush of Susan’s hot cum splash inside her tightly stretched arse and was rather shocked to find her own penis ejaculating as an unexpected rush of pleasure crept up on her with the impossibly huge cock that now felt as if it was as wide as her pelvis and as long as her torso. Susan lay on the floor, covered in a film of sweat and panting, her enormous cock still clenched tightly inside Hermione, who slouched on top of her, her head resting on Susan’s flat chest semen on her cheek and dribbling down her chin.

Almost instantly, the changes Lydia had inflicted on the pair reverted. Hermione’s ears and tail vanished and her tongue reverted back to its normal (though cum-covered) form. She let out an audible sigh as Susan’s cock disappeared, leaving her gaping anus and distended rectum noticeably empty and sore as her sphincter spasmed and clenched. Susan felt her whole body shivering with the reversion, but most markedly she smiled with relief to see her breasts reappear (a little squashed with Hermione still resting on them) and winced as her own anus was evacuated, the swollen butt-plug disappearing and to her delight not needing to be manually removed. The pair of girls lay almost catatonic upon each other on the floor as Lydia stood up and strode slowly to the door. “That was the most fun I’ve had in years, you guys are an absolute riot,” she smirked. “Fuck me Susan, fuck me hard! That was just hilarious. Anyway, I guess a deal’s a deal, you guys are all sorted out now. Rest up good, I’m definitely going to come back to see you two again. Ciao.” With that, Lydia strode out through the door and left the girls alone.

As she wandered back through the halls, Lydia recalled the blonde-girl who she had left with a vibrator up her arse stuck to her bed. She strode back through the rooms curiously until she stumbled across the young woman, in the same state Lydia had left her. She was covered in sweat, her hips rocking slightly and her thighs slick with her own juices. When she saw Lydia she begged for help, unaware this was the person responsible for her current condition. Lydia pulled the large vibrator out of her with a faint pop and a grunt and the girl collapsed on the bed with relief, tugging her panties up weakly. “Thank you, so much… This is so embarrassing, I don’t even know what happened, one minute I was sat reading and the next I was being assaulted!” She stumbled to her feet a little shakily and poured herself a glass of water, drinking it down before wiping the sweat from her brow on her forearm. The blonde-girl sighed loudly and looked over at Lydia, “I don’t mean to be rude, especially after you saved me from that but, well, I could use a little privacy, I need to get a shower and err, sort myself out, as it were.” She smiled sweetly at Lydia and Lydia smiled back.

“Where’s the fun in that? I mean, I can probably think of a dozen more exciting things to do to you.” Lydia smiled cruelly as the blonde-girl’s face fell.

“Oh God, it was you, wasn’t it?” she stuttered, backing away and futilely raising a protective ward. Just as Lydia prepared to shatter the girl’s magic and trap her again a strange thing happened: a cloud of dust rose from the floor and floated between the two girls. As they watched in silence, the dust took the form of a woman who turned to Lydia and spoke in a whispery voice, “Time’s up dearest, time to pay your fee.”

“What? No! You tricked me!” Lydia shouted in despair stepping back to the doorway. Before she could reach the door however, a second cloud of dust rose from the floor enveloped the startled, shrieking girl and vanished suddenly, leaving no trace of Lydia. The woman turned to the blonde-girl and smiled as a pair of horns and a pointed tail materialized, “If you ever find yourself in need of infernal services I do hope you’ll look me up. As long as your request is more reasonable than dear Lydia’s here I’m certain the cost will be significantly lower.” The succubus gave a curtsy and a wink before fading away, leaving nothing but a faint whisper, “Toodles!”
