YWATA: Sex on the Brain
By TwrchTwryth
Located in the sunny Arkady Mountains in the southern United States, right on the shores of Lake Haxentanz, stands the Young Witches of America Transformation Academy (YWATA, for short). This venerable institution trains young women possessing magical gifts, teaching them how to harness their abilities.

Of course, watching them in class would be boring for those mundane among us with no magical inclination. Here are some stories of what they do in their spare time...
ͼͽͼͽͼͽͼͽ
1999
Khloe Tsatsos had fallen down a serious death metal rabbit hole. A cousin had turned her on to In Flames, but now she was going deeper and harder, working her way through the catalogs of Entombed and Autopsy. Currently, she was scouring Napster to complete the Effigy of the Forgotten album by Suffocation, so focused on finding every track while simultaneously lost in the riffage of "Corporeal Jigsaw Quandary" that she wasn't even aware of her roommate behind her.
That obliviousness changed when Felice Plevny grabbed her by the headphones and jammed fifteen inches of cock through the back of Khloe's head, erupting the glans between her eyes and beginning to slide in and out.
For anyone else, this would have been a bad time. For Khloe, it was a disorienting surprise. After all, she had used her witchy transformative powers to make herself a darling slime girl and so having holes punched through her semi-fluid body was not that big of a deal. It was a surprise and, to be fair, no one had ever gone in through the back of her skull (or where there would have been a skull if she had any bones) before.
(It probably would have been less alarming if it had been previously disclosed that the reader should visualize a cute girl made out of semi-transparent, carnation-pink goo, with curly hair [also goo, just textured a little differently] colored a complimentary medium green-cyan. Her eyes had a slight waterspout-blue hue. As with most YWATA students outside of class, Khloe was naked in her seat but for her headphones.)
"OOOOOOOooooohhhhwwwhhhh ?!?" Khloe groaned, her eyes rolling up and crossing. Not only this violation not at all expected, the sensation of having Felice's hard prick pass straight through her head was a completely new one.
Felice grunted in pleasure. The warm, viscous firm-but-yielding texture of Khloe's ooze body provided a delightful vessel for her pleasure. With Khloe's head transfixed, Felice removed her roommate's headphones, took hold of her pliant head, and began to really start pump away.
In her junior year, Felice had mostly kept her body normal. She was still a tan, brown-eyed brunette. Maybe she was a little taller, a little more muscular, but not to an uncanny degree. She had fallen in love with having a cock and topping people during her freshman hermography course, and since then almost always had a robust male member on her body.
Khloe's inarticulate moans just spurred on Felice's arousal. They seemed to indicate that Khloe was enjoying this sudden invasion. Felice grunted out her own appreciation and worked hard and worked fast, ramming her cock in and out of the slime girl's head.
Felice didn't set out for this to be a long, involved session. She worked fast and hard to use Khloe's gelatinous body for her pleasure and that blitzing alacrity was itself part of the thrill. It was only a few minutes before she came with a grunt and a sigh of relief, holding Khloe's head far enough from her hips that her ejaculate flooded the gummuous space behind Khloe's eyes.
"Whew, that was fun," Felice groaned, patting Khloe on the head before fully pulling out.
Khloe was still for a couple moments, her eyes still rolling around as the hole made by Felice's shaft closed back up and her body absorbed the jizz left in her head.
"I-I-I-I" Khloe stammered as her mind finished a hard reset. She shook her head, blinked quickly, and spun around in her chair, taking advantage by her lack of solidity to simply spin 180 at her waist without moving her legs or hips.
"WHAT THE FUCK WAS THAT, FELICE!?"
Felice just grinned, a little rakish, a little sheepish, a little unsure. "Surprise! Thought I'd try something new."
"You can't just -- you fucked a hole in my head!" Khloe fumed, trying to figure out just how upset and violated she should feel about something that clearly had no long-term impact and, aside from the disorienting surprise, actually felt fine.
"Yeah, I, uh, I heard one of the pixies bragging that their favorite sports team 'skull-fucked' someone else's sports team, and I just -- it gave me an idea, right?" Felice's expression was angling more towards sheepish as she gauged Khloe's reaction. "I...figured that of everyone I knew, you...you could get by with some skull-fucking."
Khloe squeezed her eyes shut, nose scrunched up, her blue face inscrutably creased with discombobulation.
"Was it...did it hurt?" Felice asked.
"No, it was...kinda nice?" Khloe looked up under beetled brow. "But just...really disorienting and surprising and...the disorientation was overwhelming, y'know."
"Sorry..." Felice blushed, looking down at the floor.
"No, it's...it's okay. Just next time you want to scramble my brain, warn me first, okay?"
"Uh, yeah, sure..."
Khloe shook her head one more time and then spun back around. A shiver went through her before she picked up her headphones. Felice let out a small sigh of relief and turned to find her Quantum Gramarye textbook; she had a test coming up and needed to do some studying.
"Oh, but don't think this will go unavenged," Khloe called. "Some time, when you don't expect it, I'm gonna get you."
Felice laughed and shot a cavalier grin over her shoulder. "I'd be surprised if you didn't."
ͼͽͼͽͼͽͼͽ
Five days later...
The test seemed to go well, Felice thought. She felt like she nailed the application of non-trivial zeros in runic dwimmercraft. It was energizing and in her post-test boasting, she had made certain promises to fuck Jenny Hilbert hard enough to knock her organs loose. That might have been some boastful exaggeration, but she was eager to give it an honest shot.
She just had to drop off her text books in her room, then head one floor down in Riemann Hall to where Jenny and her double vaginas were waiting.
Unbeknownst to her, she wouldn't arrive that afternoon.
Felice found the room empty and, without thinking twice, tossed her bag onto her bed and quickly removed the simple modesty gown that most students wore the class. (Public nudity was okay in downtime, nudity was often a feature of learning in class, but it was still expected that students dress when going to class.) She paused to give herself a quick once over with her deodorant, just to be sure, and then it was her turn to be surprised.
She had never looked up. The ceiling was covered in a thin film of carnation-pink slime that started to congregate into a mound as Felice undressed. As soon as Felice set down her deodorant stick, a thick pseudopod shot forth from the mass to wrap around her waist and pull her off her feet.
Felice squealed in surprise and a little panic, but this was cut off as she was quickly yanked into the squamous mass. Her panic subsided when she realized that it was Khloe who had ambushed her in this protoplasmic, suspended manner, but that turned into annoyance. She was really looking forward to fucking Jenny.
"Not cool," Felice tried to say, but she was unable to articulate through the semi-fluid composition of Khloe's blob form. Opening her mouth did get her a taste of Khloe's delightful caramel flavor. Of course, Khloe was also getting a taste of all Felice's body as she completely enveloped her roommate.
This was far from the first time that Felice has been engulfed inside Khloe's amorphous form. It could often times be very rewarding, sexually, when your partner could stimulate your entire body simultaneously with near infinite dexterity. Felice was looking forward to that now if she was going to be distracted from spending time with Jenny.
However, stimulation wasn't the only thing that Khloe could do when she cocooned someone. Instead of feeling Khloe playfully invade her orifices and stimulate her cock, Felice felt her skin start to tingle and fizz.
"Oh, fuck off, Khloe," Felice griped. As her body began to dissolve -- a mildly weird sensation, but not a painful one -- her annoyance gave way to begrudging respect with the delayed realization that this was probably revenge for the surprise mindfuck a few days earlier. Well, this was certainly a fitting ambush too.
Felice was fully disintegrated and absorbed within seconds; Khloe's goo form was very effective when she wanted it to be. With a wet slurping/popping sound, the blob of slime girl dropped detached from the ceiling and dropped to the floor, where Khloe resumed her typical, humanoid form.
"Told you I'd get you when you least expected," she remarked, looking down at her nude form. There was no sign of Felice. After a few more moments of gloating and smirking, Khloe returned to her computer and booted up Napster again. She was still two tracks away from finishing off Once Upon the Cross by Deicide and she was determined to try to find them.
The other good thing about getting revenge on Felice was that for the time it took her to reform, at least, Khloe didn't have to use headphones. She really cranked up "Behind the Light Thou Shall Rise" and got to work.

Two-ish weeks later...
There was a lot of profligate, casual, fun sex to be had at YWATA, being as it was an environment filled with energetic young women experimenting with their bodies and able to enchant away any consequences.
So it wasn't unusual or surprising or anything that on a lazy rainy Saturday afternoon, Khloe and Felice were fucking. It was a four-way, actually, with two friends. There was Jenny Hilbert, the cute, spunky brunette with chestnut hair, freckles, and two vaginas, and Aubrey Wilson, a Black, three-foot tall mini-futa with a twenty-inch cock and a perky afro.
At the moment, the four were on Felice's bed. Jenny was on her hands and knees, head on the pillow, while Felice plowed her right-side pussy (having already come in the left). Aubrey was arranged behind and a little under them, head on another pillow at the foot of the bed. Khloe rode Aubrey in a mostly reverse cowgirl orientation, though her legs were melted into a puddle around Aubrey's lower body. Aubrey's disproportionate dick penetrated all the way up into Khloe's chest and was visible through the slime girl's semi-transparent body.
Khloe wrapped around Felice's waist, literally, so she could watch her roommate fuck Jenny. At the same time, she was working everyone else; tendrils from her lower half invaded both Aubrey's and Felice's sexes and anuses, while her left hand plunged into Jenny's left pussy and her right hand reached into her own body to give Aubrey a handjob within her own birth canal. Khloe was very good at this and very dexterous.
They had been at this for a while and were approaching another climax (everyone had cum a couple times already and, thanks to some magical reinforcement to their stamina, they were probably expecting a few more rounds). Felice came first, filling Jenny's second pussy with her jizz while she convulsed around Khloe's invasion. The gasping grunting sound of her orgasming (plus Khloe's multifaceted ministrations) triggered Jenny, whose screams helped set off Aubrey into flooding Khloe's gooey body with her own load. Khloe shuddered a bit, experiencing a full-form orgasm that, while intense, was not very disorienting.
As everyone came down, Jenny collapsed on her stomach and Aubrey sat back on her haunches. Khloe flowed around the other three until she was laying on her side beside Jenny, tracing a viscous finger along the the brunette's back with a gentle affection.
"Hey, Aubrey, wanna see something cool that Khloe and I found recently?" Khloe felt a ripple of recognition as soon as she heard Francine's word.
"What's that?" Aubrey asked.
"Felice..." Khloe looked up, trepidation weaved into her voice.
"C'mon, let's show them some skull fucking!" Felice climbed down and stood up beside the bed. "Won't be a surprise this time."
"Oh, now I'm curious!" Jenny looked over at Khloe, giving her a smile that was excited even while the rest of her face was a little flushed and tired.
"C'mon, you can't tease it and not at least tell us..." Aubrey protested.
"Can we?" Felice asked through her own wolfish grin.
Khloe let out a sigh. She wasn't really opposed to it, she was just a little anxious about the scrambling effect the previous session had on her mind. Sure, there was a lot about it that felt good, but it also felt kind of like her brain had touched a low-current electric fence.
Still, it wasn't exactly bad, so the eagerness of Aubrey and Jenny to see something new egged her on to accept.
"Okay, fine, we can show them." Khloe made a big show of magnanimously accept before flowing in a teal torrent over Jenny's back (squeezing the brunette's ass along the way) and reforming into a kneeling human form by of Felice, facing the bed. She leaned onto the mattress a little as Felice stepped behind her.
"Let me know when you're going," Khloe requested while Felice took hold of her semi-pliable head in one hand. The other was angling her cock.
"Okay, here we go in 3--2--1--now!" Aubrey and Jenny both gasped as Felice thrust her prick into the back of Khloe's head again, angling up in a way that would have transfixed the slime girl's cerebellum and temporal lobe if she had a brain, and once more erupting between her eyes. The sudden and violent-looking insertion surprised the other two watching.
It was definitely more pleasant for Khloe this time around. Her mind was immediately a fuzzy, disconnected mass of feelings barely able to form a cogent thought, but the fact that she was expecting the intrusion removed a lot of the baffled uncertainty she had felt when Felice had ambushed her. And it still felt a little good.
"Skull fucking," Felice chuckled and started to give a few measured thrusts.
"Is she okay?" Jenny asked. Khloe's eyes were rolled back and crossed, like they were unavoidably trying to look at cock transfixing her head, and her jaw was slack.
"Yeah, I guess it kinda scrambles her brain for a little bit, but she told me it doesn't hurt," Felice assured her. "I mean, you know how flexible she is."
They had all seen Khloe play around with her gooey body in ways that would kill flesh and blood people, including passing objects through her form, dividing, splitting, and splatting about, so this was all very believable to them.
"Here, I was gonna try something a little different this time..." Felice said to herself after a few more thrusts. She pulled back until just the tip of her dick was in Khloe's head, worked on changing the angle a little bit, and then jammed into her roommate again. This time her glans erupted out of the side of Khloe's jawline.
"Oh, not quite right," she muttered and withdrew again.
"Going for her mouth?" Jenny asked, sitting up. Aubrey, who had been fairly quiet during this display, had crawled to the edge of the bed and was watching with definite interest while stroking her cock.
"Hell yeah, I wanna reverse blowjob!" Felice laughed. Khloe's body finished sealing up the tunnel in her face made by Felice's invasion. Felice had been waiting for that and slammed her hips to the back of Khloe's head again, this time finding the right angle for her cock to part Khloe's jaws and emerge from her mouth.
At the same time, since she wasn't in Khloe's mind-space any more, Khloe was herself starting to regain some agency. Her eyes blinked and now they crossed and looked down again to see Felice's dick extending a good six or so inches out of her mouth. She grunted with some of surprise, unable to speak around the phallus that filled her mouth from behind.
(sure, she could have just formed another mouth or head somewhere else on her protean body, but she was still foggy from having Felice's dick in her mind again)
"Want some help with that?" Jenny chuckled. Not waiting for a response -- which surely would have been a yes -- she leaned forward as Felice drew back and placed her lips on Khloe's in a sweet, open-mouthed kiss that turned into a two-person performance of fellatio when Felice thrust again. She could taste Khloe's sweet flavor all over Felice's rod.
"Oh shit yes!" Felice exclaimed when she felt her member pass through Khloe's warm ooze into the firmness of Jenny's mouth. Different sensations, both of them spectacular, and she sped things up while taking hold of Jenny's head with one hand.
Everyone stopped talking as Felice used both of them. Khloe and Jenny were unable to speak, of course, while Aubrey was too fascinated and Felice was too involved in the process. Jenny did fondle one of Khloe's breasts as they were used, which added a bit more pleasure for the exploited slime girl.
Felice gripped them tight enough that Jenny's face was starting to deform Khloe's. No one was worried about it, this was definitely the preferred crumple zone, so she just focused on mixing the blowjob and kissing while trying to give Khloe some groping fun.
The novelty and excitement made it too much for Felice to last long. It only took a few succulent minutes before she pulled down on Jenny's skull, slammed forward with her hips (further crumpling Khloe's pliable head) and shot another cup of jizz down the brunette's throat. It was so far back in her throat that Jenny barely tasted it; after a few years at YWATA, she had no problem swallowing it all.
When she was fully drained, Felice stepped back, withdrawing from Khloe as Jenny sat back. The goo girl's head was pretty disfigured at this point, but after a second or two she gave it a good shake and it whipped back into shape (though her eyes kept spinning comedically).
"Whoa," Khloe murmured, composing herself. "That...I mean, that wasn't as disorienting as between the eyes..."
With an audible plop, Aubrey dropped her shaft across Khloe's head and breathed out a sultry "Hey."
"Hey, uh," Khloe looked up at the mini-girl, who was standing on the bed. "What, uh...?"
"I wanna fuck your brains out too," Aubrey crooned, rubbing her thick member against the slime girl's green hair. "Pleeeeeease?"
Khloe made a show of gulping. She was nervous -- Aubrey's prick was a bit bigger than Felice's and she didn't exactly know what Aubrey was planning -- but again, it had never exactly felt bad, and was a bit less discombobulating when she knew it was coming.
"How do I say no to that?" Khloe chuckled.
"Fuck yeah, girl, I got a great idea." With one hand, Aubrey moved Khloe's head to the side a bit while she readied her cock with the other. For a moment, Khloe felt the head of Aubrey's prick press up against her ear canal. She tried to ready herself, but the next moment the only thing going through her mind was that dick, which lanced straight through her skull and out the other ear with a single strong thrust.
"HO-LEEE SHIIIIIIIIITT!" Aubrey exclaimed, looking at her handiwork before drawing out park way and then plunging in again to her hips. The sensation of Khloe's viscous body was incredible enough, the novelty was fantastic, and the sudden dull, slackened look on the goo girl's face as her consciousness was obliterated by twenty inches of turgid cock was just icing on the cake.
Aubrey reveled in skull-fucking Khloe from ear-to-ear. She grunted and growled as she pummeled the slime girl, fulling engaging her dominant side. She only slowed down a bit when Jenny remarked "Oh shit, you can see it behind her eyes!"
Felice moved around so she could watch too. Aubrey could somewhat see her prick through the semi-transparent shades of Khloe's body, but the layer of hair made it harder for her. Apparently, her shaft was easily visible as it passed through her head.
"Whoa!" Felice exclaimed, Aubrey picking up the pace again. "That is so cool!"
There wasn't a lot more talking, just the wet squelching sounds of Khloe's (not) skull being violated and Aubrey's grunts of pleasure. Khloe was slack-jawed, her eyes rolled back, and her ability to think more or less vaporized.
The novelty was a major aphrodisiac and Aubrey didn't take long. Lunging forward after a few minutes, she squealed in ecstasy and shot thick volleys of pearly cum out of Khloe's other ear, splatting against Felice's dresser a few feet away. The hermaphrodite's body shook as she came and clutched Khloe's head so hard as to smash up her features.
She spasmed so hard and clutched Khloe so tight that, mid-orgasm, Aubrey fell off the bed and into Khloe's body. In a normal situation, the junior's body would have either supported her or maybe enveloped her, but in this case the sudden jolt relieved the tension and inertia that was keeping Khloe's form together.
Khloe splashed apart under Aubrey, going almost fully liquid as there wasn't enough mind here to keep her body together. She became a thin, expanding puddle of pink fluid pooling across her dorm room floor and splattered on Aubrey's body.
The other three students laughed, none more so than Aubrey. She may have been soaked in Khloe's sappy remnant, but she found it pretty funny.
"Oh man, I guess I really fucked her brains out, huh?" Aubrey grinned at the other two, a dollop of jizz dripping from her cock to mix with the inchoate liquids of the goo girl.
"Wow, I bet that had to be...something," Jenny mused. "She'll be alright, right?"
"Yeah, I'm sure," Felice responded with a confident shrug. "Either she'll pull herself back together or one of the reformation wards will get her."
"That's probably true," Jenny nodded. Aubrey splashed around in the puddle of Khloe a little before wiping some of her friend off of her thigh and slurping it off her fingers.
"Delicious," Aubrey murmured, casting a suggestive look at the other two. She applied another of Khloe's dissociated body to her cock and aimed it at Felice. "Want a taste?"
ͼͽͼͽͼͽͼͽ
Nine or so weeks later...
Naviknob: Khloe's out, how about you come up for some fun?
Aubrey read the AIM message with a little thrill. She always had fun with Felice. Groups were nice, but one-on-one could be pretty rewarding, fucking and getting fucked by someone who knew their way around the hermaphroditic form.
MissAub79: Five minutes.
Seven minutes later, Aubrey and Felice were locked in a face-fucking 69 on Felice's bed. No words had been spoken, just immediate horny engagement. Four minutes later, Aubrey was on top of Felice, thrusting into her en route to a quick climax, which she expected to be the first of several.
"Ooooohhhh," Aubrey moaned, nuzzling into Felice's breasts as she came down from her high. "You feel so good...I can't want to get back to fucking you, but it's your turn now, if you want me."
Felice just smiled. The lack of talking was actually beginning to feel intentional and Aubrey wasn't exactly sure what she was getting at. She decided to play along for now, especially when Felice forcefully spun her around and then once again, until Aubrey was on all fours, Felice towering over her diminutive form. Aubrey could swing either way with a little rough play, dishing it out and taking it, and this manhandling was pretty hot.
Even when Felice slammed home in Aubrey's ass. It was a very nice butt, to be fair, and thanks to a little enchantment she had learned in her first couple weeks at YWATA, always able to take even a surprise invasion with minimal discomfort. It just wasn't what Aubrey was expecting and she did squeal a little.
Felice paused on the withdrawal, so Aubrey looked back over her shoulder. "No, sorry, just--surprised. Go for it."
The grin that crossed Felice's face was a little more cruel than Aubrey expected, but it had enough salacious excitement that she let it go and just focused on enjoying the pounding of Felice's hips driving a foot-plus of cock most of the way through her body. Anatomy and physics gave way to the sorcerous sodomy.
Felice was driving, energetic, determined. She pulled on Aubrey's shoulders and arms, utterly dominating the half-pint hermaphrodite. Aubrey screeched in pleasure, playing into their size difference and her apparent helplessness. It felt like she was being split by an angry telephone pole, but in a good way.
This kept up for a few minutes before Felice slammed herself all the way up to her hips into Aubrey and let out a deep, animalistic bellow. Aubrey could feel the sudden pressure in her chest cavity as she was flooded with cum.
A lot of cum. And it kept coming. There were some witches who liked ludicrous deluges of ejaculate, but that wasn't Felice's scene. This was something different and it kept going.
"Oh my god, that's so much!" Aubrey gasped, looking over her shoulders. Felice, biting her lip, made eye contact. In that moment, her normally brown eyes were covered with a waterspout-blue film.
The same color as Khloe's eyes.
There was a wink, another blast of cum deep inside Aubrey, and then things started to get even more wild. Aubrey's breath and voice were taken as the gallon or more of fluid that Felice had pumped into her suddenly surged, moving on its own up Aubrey's esophagus. She barely had time to cough before a thick mass of carnation-pink ooze erupted out of her mouth.
Aubrey squealed, muffled as it was. This was quite a surprise. It didn't hurt, but it felt weird and extremely unexpected.
The ooze kept coming, flowing down over Aubrey's body, though it left her eyes and ears uncovered at first. As the cocoon was finishing, 'Felice' leaned down, still deep in both ends and spoke directly into Aubrey's ear. Her voice was Felice's but it came out awkward and gangly.
"This is for you guys fucking my brains out," came the explanation. "Payback time!"
The slime now fully encased Aubrey's head as 'Felice' leaned back. She withdrew her member fully from Aubrey's ass, but it left a strand of pink ooze behind, connecting the two. This departure allowed the slime to completely envelope the smaller hermaphrodite.
There were a few long moments of gloating, letting Aubrey really feel the ambush set by the slime girl. Aubrey played along, squirming and moaning a little, but there wouldn’t be hard feelings. This kind of one-upmanship was pretty common at YWATA. She would have to think of some other way to prank Khloe.
Once she reformed, of course. After this bit of triumphal, silent taunting, Khloe quickly absorbed Aubrey, dissolving her body in seconds and leaving a keg-sized lump of ooze on the bed, still connected to Felice.
There were a couple seconds of reorientation and more of Khloe’s protoplasm began to leak out of Felice’s mouth. Now that Aubrey was gone, she didn’t have to stay completely inside her roommates body. In fact, she didn’t need to pilot Felice’s body anymore. This was probably enough payback for Felice introducing Aubrey to skull-fucking…
The amorphous mass of ooze now swept over Felice’s slumped, motionless form. This time there was no gloating, no prolonged and triumphal posturing. As soon as Felice was fully within her mass, Khloe absorbed her with all speed. Matter-of-fact, efficient, fast, and complete.
Khloe reconstituted her normal body soon after Felice’s was gone. She stood up and stretched, contented with her little ambush. She had found a novel use of her preferred form and cheekily gotten back at both of the skull fuckers. And now she had her room to herself for a couple hours, meaning Felice couldn’t complain if she played music.
With “Slaughter of the Soul†blasting loud enough to send visible vibrations cascading through her body, Khloe leaned back and wondered about how Aubrey or Felice would try to get her back.
