END OF SPOILER 

Skylar slumped back against the headboard of his narrow dorm bed, the afternoon light slanting through closed blinds and curtains to keep out the growing spring heat. The room was typical sophomore chaos– a small single with plain walls he’s tried to warm up with cheap tapestries, a desk covered in work, and a laptop still open on his last set of notes he was reviewing. At five-foot-five with a slender, almost delicate build, he looked like he belonged in a pixie-cut indie rock band. He had long blonde hair that fell into his eyes, and his face– soft jaw, full lips, high cheekbones– had earned him enough confused glances over the years to force him to come to terms with it.

It had taken him quite a while, but he had finally accepted his body for what it was. The way his clothes hung on him like they were meant for someone else, the way his cock stayed stubbornly small, barely an inch soft and finishing at a pitiful 3 inches when he was actually hard. Combined with the fact that every time he went to the gym he would be surrounded by Folk with giant horse cocks, huge knotted canine cocks and exotic barbed feline cocks, and even just plain human cocks that put his own to shame in the changing room, and he had little other choice than to accept the limitations of his member’s size. 

But, accepting it had unlocked other doors for him, like the deep, aching need to be pushed down, used, told what to do. Laila had sniffed that out within the first few weeks of him arriving on campus, and leaned into it hard. In public, she was the sweetest Lupine ever, all smiles and handholding. But behind closed doors, she became the dominatrix that got off on breaking him down until he was whimpering her name like a pup in her first heat.

His phone buzzed on the comforter next to his face. A text from Laila had come through.

“Group project running late. These pups are dragging their paws on everything…Might not come by till way later tonight, if at all. Don’t wait up, cutie <3”

“How will I sleep without my personal heater? :(“

“I’m sure you’ll manage…but if you need something to tide you over, I could heat you up with a little steam…? >:3”

Skylar’s breath picked up a little as he replied. “Yes please!”

“You know what to say, bitch~”

Skylar’s cock twitched in his shorts. He licked his lips, thumbs swiping across the keyboard. 

“Please Mistress, your pathetic little human is already hard. I need to see you”

There was a long pause, and then three dots appeared on the screen.

“Good boy~ don’t move”

Minutes scrolled by. Skylar shifted restlessly on his bed, palming the small bulge in his shorts. This was not how he had planned to start his afternoon, but he never passed up a chance to see his girlfriend's body, and it would make perfect material for later when his original plans started…

His phone lit up with a new message, with a photo attached.

“Want more, or is this enough for you to get off on?”

Laila had taken the picture in a campus bathroom stall. She was tall and sleek, like most Lupine were before their first pregnancy. Her sharp brown eyes that had the ability to pin him in place were narrowed and hungry. Her long black hair was tousled and hanging down to frame her face, her snout curled in the knowing smirk that always made his stomach flip. Her glossy dark fur that felt like warm silk under his fingers shimmered in the light. She had pulled her shirt up just enough to show the underside of her C-cup breasts, her bra lying on the tile floor. One of her hands was cupping a tit, the other dipped lower, fingers teasing the waistband of her very tight shorts that were barely containing her firm ass that she loved grinding against his face.

“Fuck! You look great, Mistress…may I please have more?”

“Beg properly.”

“Please, Mistress, I’m so horny! I’ll do anything for you tonight.”

A second later, a new photo arrived. This one was filthier. Laila was sitting on the toilet. She had pulled her shirt completely up, showing off her pierced nipple, and had shed her shorts and panties. She was seated so the camera could get just the barest glimpse of her curvy ass and had a front row seat of the pink lips of her pussy.  Two fingers were buried knuckle-deep inside herself, soaking her hand in her juices.

The message attached to the photo read “That’s my good boy. Enjoy looking at your dinner you can have when I get over there eventually. For now, stroke your cock for me, but NO CUMMING. I want every drop for later. Gonna milk your boy-button dry with your favorite knot until you’re begging me to stop. Sound good?”

“Yes~!!! Thank you~!!! <3 love you”

“Love you too, see you later <3”

He stared at the pictures, breath coming faster, hand already slipping into his shorts to tease his stiff three inches. The denial and anticipation only made it hotter. Laila always knew exactly how to wind him up and leave him desperate.

He stared at the pictures, breath coming faster, hand already slipping into his shorts to wrap two fingers around his stiff three inches. The denial made it hotter. Laila always knew exactly how to wind him up and leave him desperate.

With a moan of desperation to keep going, he pulled his hand out of his pants. I’ve got a way better orgasm to get to… he reminded himself and rolled out of bed. 

He stripped, and did the usual last glance at himself in the mirror. His long hair, his thin androgynous body that usually made men on campus double-take and ask themselves if they had just stared with hunger at a man or a woman. His small penis that was currently throbbing with need.

He took a deep breath and reached under his bed without having to look and pulled out an old shoebox. Inside was a small bottle containing a single glossy pink pill. It had arrived yesterday, a  day earlier than usual, and it had taken all of his willpower to not take it that morning. But now it was Friday. He had no classes tomorrow, and could spend all night and all day tomorrow recovering.

The pill was a part of his guilty little ritual. Once every couple of weeks, when the pressure built up and Laila was busy or not in the mood to peg him senseless, he ordered the pill, locked the door as soon as it came in, and spent a few blissful hours as Her.

His heart raced as he tore open the bottle. Next to the pill was the same little instructions card they always included. He’d long passed the point of needing that, he was an expert at it now. Inked on the pill were two words in tiny bright blue script: “Cross-Shift,” the name of the company that had unlocked a new avenue of pleasure for him and thousands of other people across the world.

He popped it into his mouth, chased it with a gulp of water, and got back into bed, his body tingling in anticipation as he waited for the familiar tingle that would herald the changes.

He tried to sit still, he tried to steady his mind and wait patiently, but, far too aroused already, his hands crept down. One found his left nipple and began teasing it, pulling it and pinching it to coax pleased soft moans from his lips, and his other wound down to his crotch, rubbing his cock with two fingers instead of stroking it as the haze of arousal swelled in his mind.

The change hit him harder and faster than ever before.

The same familiar heat began, as it always did, in his chest and began to spread through his body, but where it was usually like wading into a warm jacuzzi, this was like his body was being flooded with molten syrup. It filled every nerve, flooding his body with stimulation. Skylar gasped, his back arched as the orgasmic changes began. His flat chest swelled into massive, heavy breasts. Fat, sensitive nipples stiffened instantly, each throb shooting white-hot pleasure straight to his groin. His hips cracked wide with a wet, satisfying pop, thighs thickening dramatically into his hands before the pleasure became overwhelming and they began squirming and clawing at the sheets beneath him. Soft, jiggly flesh poured onto his body in all the perfect, feminine places, turning his once-slender frame into something shamelessly thick. His waist tightened dramatically, carving a new figure while his ass ballooned into two huge, plush globes that lifted his back slightly off the bed.

“Oh~ Oh my God- F-fuck-!” his voice cracked higher and higher as he choked for breath in between waves of pleasure. His already soft voice turned into a series of high-pitched, needy cries of pleasure as he moaned at the ceiling

His balls tightened, and he felt them melt inwards until they no longer existed. His cock leaked a flood of precum in dumb pleasure, then began to shrink as well. From 3 inches it shriveled down to a small hot-pink nub where it spurted one last gush of precum and was no more than his new, throbbing clitoris. Then, he felt a new wetness bloom lower, between his thighs as a slick, puffy pussy formed and a new heat and hunger grew in him. The final wave crashed through him, an almost orgasmic surge that left every new curve tingling and hypersensitive, his fat tits heaving, thick ass jiggling underneath him, needy pussy clenching around nothing and soaking the sheets.

And the transformation was complete.

Panting, Skylar stumbled to the mirror on shaky, thunderous thighs. He always loved looking at himself freshly after the transformation in the mirror, and pushed himself to ignore the aching need in his body to make it to the mirror.

The woman that looked back in the mirror was almost unrecognizable. She was pure, exaggerated pornographic fantasy made natural and real. The hair was still the same color and length as Boy-Skylar’s, and so were the glassy green eyes, and yet they were different after transforming. The golden curly hair now framed a flushed face that looked like it was built to serve, and her eyes were dark with a hungry lust that ached to be fed. Her lips were even plumper than Boy-Skylar’s were, turned into plump pillows perfect for worshipping others. Her body was a deliciously thick human hourglass with a huge pair of tear-drop shaped F cup breasts that hung heavy and full, capped with pink nipples that were already at attention. Below them, a cinched waist that held the slightest amount of chub, just enough to grab onto. That waist flared into a set of wide, fertile hips and a shelf-like ass that would clap and ripple with the slightest impact. Between her thick thighs, her new pussy glistened obscenely, lips puffy and dripping down her inner legs. She looked like she existed to be kept in a state of orgasmic bliss at all times.

I must have been hornier than I thought, Skylar thought. It’s never hit like that before… His, or, her, hands strolled over herself. They roamed greedily, squeezing the soft weight of her tits until milk-white flesh bulged from between her slender fingers and erotic moans purred in her throat. Then, both hands traveled downwards, one playing with her asscheeks while the other traced her soaked slit and she moaned shamelessly as shocks of pleasure threatened to buckle her knees.

Eager to start relieving all of the stress she had built up as a man, and just as eager to cum her brains out, Skylar hopped back to her bed and grabbed her phone. Closing her chat with Laila, she went to her gallery and pulled up every nude photo Laila had ever sent her before.

Boy-Skylar, as much as he enjoyed it when Laila pegged him senseless, always considered himself straight…or at least, only attracted to women with the desire to wear a strap-on, at the furthest. So, whenever Boy-Skylar transformed into this voluptuous queen, Girl-Skylar always thought of herself as a lesbian. Hours of teasing herself, rolling through multiple back-to-back orgasms to pictures of Laila and lesbian porn videos, left her a panting, drooling mess until the pill wore off a few hours later. She’d thought about buying some toys, or a dildo, but that had seemed like one step too far in a direction she was not willing to go. So, she was content to use her fingers. She had gotten quite good at it by now, and was able to edge herself or make herself cum as much as she wanted to for the few hours she had with the Cross-Shift pill.

She found the first picture that made her heart skip a beat, a picture of Laila, wearing a short skirt and a very tight shirt. She was sitting on a bench somewhere in public, her legs spread and showing off her bare pussy underneath the skirt, a slit of pink among her perfectly groomed dark fur. Her hand was closed in a loose fist around her open mouth, and she was looking at the camera, a sly look in her eye as she allowed a strand of drool to leak from her muzzle. The caption on it read “If only you were here…which would you rather be? Eating me, or getting eaten? <3” 

The thought threw her into a fantasy that swallowed her up. She kneeled on her bed to better float down into the fantasy and let her hands roam as they liked between her breasts and her pussy. The room went hazy, and in her mind she found herself in public, kneeling below the tall canine woman spread on the bench before her. 

“I said get to work,” Laila growled with undeniable arousal in her voice. Skylar blinked up at the Lupine, panting with need as a thousand ideas on how to please this furred goddess before her swam in her mind. Laila laughed at her. “God you’re useless when you’re horny, just a braindead slut meant to be used.” Though her words were degrading, they were said with such a strong affection and need that it made Skylar’s hips buck forward. Laila rolled her eyes and grabbed Skylar by the back of the head, slowly guiding her to her warm, juicy lips between her legs.

With a shuddering moan of delight, Skylar instantly began devouring the treat, but Laila pulled her away just as soon as she dove in. 

“Ah-ah!” she warned, teeth bared. “You go at my pace, since you couldn’t be assed to do it yourself. Tongue out, slow licks while I coat your face and show everyone whose bitch you are. Got it?”

Skylar nodded again, lips pouting a bit before sticking her long tongue out and feeling her delight at being used fill her body with electric tingling down to her fingers and toes. She felt like her whole body was buzzing as her face met Laila’s pussy again and was roughly, slowly dragged up and down, only being allowed the slightest taste of Laila’s delicious ambrosia before being forced to kiss the wolf’s inner thighs sloppily. 

“Tongue in, and take a deep breath, then start sniffing deep,” she commanded. When Skylar had done as she was told and was starting to let the inhale go, Laila tugged sharply and began rubbing her faucet-like pussy up and down Skylar’s face, grinding her hips hard into her face and mouth. “Don’t you dare lick me yet, just sit there and sniff while I use you,” she warned in between grunts, moans and swears. Skylar’s eyes rolled as she began sniffing deep, inhaling Laila’s arousal until it was all she could smell, until it became her whole world. She knew she would smell like Laila for weeks, and she didn’t care. She wanted everyone she passed to know how much of a submissive bitch she was.

Meanwhile, Real-Skylar brought one hand down to her breasts and started kneading the flesh roughly, more roughly than she usually did to herself. She knew she would leave bruises, but she was too lost in her fantasy to care. Her other hand dropped to her pussy. It was throbbing, and Skylar wasted no time with teasing herself like she usually did. Instead, she pressed her finger against her swollen clit, using her juices as lube, with the slightest pressure. She knew exactly how hard to press, how small the circles should be, when she should stop rubbing in circles and just start going to town on herself as she approached orgasm. She melted into the pleasurable fantasy, stoking the fire within her as she inched closer to the edge. It was taking much longer to get her first orgasm, but this daydream was so pleasurable she would never complain.

“Oh fuck~” Skylar moaned in desperation after a particularly good wave of pleasure ran through her.

“I agree~” A new, confident, sultry voice mewed delightedly in her head. “Look how that juicy cunt’s twitching. Bet it’d feel nice stretched around a fat cock~”

Skylar’s next moan hitched in her throat, frightened. She looked around the room, thinking she had somehow left a porn video playing, because the woman’s voice sounded like erotic honey in her ears. After a moment of not hearing anything, she shrugged and resumed pleasing herself.

The fantasy came back in full force, but this time, she was bent over the park bench, swaying her hips behind her, feeling her pussy leak down her thighs.

“Look at you~” an unseen Laila teased from behind her. “So ready and eager for me. Do you want my knot that badly? You wanna be bred like the bitch you’re acting like?”

“Yes~!” Skylar moaned breathlessly in both the dream and reality. She was dimly aware that her hips were grinding harder into her open palm beneath her, but only insomuch that it was pleasurable.

The fantasy dove deeper into her mind, blocking out any possible distractions. She was in the park, ready to be used by her girlfriend.

Something heavy landed on top of Skylar’s bent rear and began to hump eagerly up and down her back. Skylar knew what it was, her favorite knotted canine strap-on Laila liked to use on Boy-Skylar in real life. It felt like a fantasy to even refer to herself as a man, because right now all that mattered was she was about to be filled. The strap-on cock was hot, like it had been kept in Laila’s tight ripped jeans all day, and was dripping lube as if it had been waiting to get inside her for months. Skylar could see it now in her mind: bright red, a shaft of 8 inches, with a knot a little smaller than her fist at the base. She had never taken the knot as Boy-Skylar, but she knew her achingly wet pussy would swallow it the way it deserved to be.

“Beg me for it,” Laila teased and let the cockhead dip lower and lower, until it was grazing against her outer lips. Each movement made Skylar gasp and choke out in anxious delight. Her brain was going fuzzy.

“P-please,” Skylar managed to say in a husky voice. “Please Mistress, I can’t take it much longer. Please fuck me~! I’ll do anything!”

“Anything?” Laila repeated in a teasing tone. “You gonna have my pups? You gonna clean my cock when I’m done with you? You gonna take my knot in all your holes?

“Yes! Y-yes, yes, please! Just let me cum, please Mistress!”

Laila gave Skylar’s ass a vigorous slap of approval and grabbed both of her wide hips in her small but vice-like hands. The strap-on cock was aimed at her walls, all it would take was the slightest pressure from Laila’s hips and she would be inside. Skylar wanted to push back, to feel her finally enter, but Laila was holding her firmly in place, forcing her to whimper and whine impatiently like a pup in her first heat while she pushed her cockhead ever so slowly into her. She felt the pointed tip sliding effortlessly into her centimeter by torturous centimeter. Her body wasn’t putting up even the slightest resistance, welcoming the intrusion with lewd abandon.

As imaginary-Laila pushed into her pulsating walls, Skylar’s fingers followed suit in real-life, mimicking the movements she was imagining. The head pressed fully into her and her walls clenched violently and rhythmically around the invading rubber cock, like it was trying to milk it for every drop of cum it could get. Then came her shaft, widening as the middle approached and then thinning out again. It felt like her fingers sliding inside of her, only fuller, thicker, and much more satisfying. Finally, she felt the knot hit her folds and pressed. Her lips kissed it as Laila pulled herself back and forth, scraping up her insides and forcing her to gasp for breath as she pushed her knot closer and closer to entering.

On the third try, the knot slipped inside with a wet “SQUELSH~!” And Skylar quivered in fullness while Laila roared in triumph.

“That’s a good girl~” Laila cooed as her hips met Skylar’s thick ass and began grinding. “Like you were meant to take cock.”

Encouraged by the degrading compliment of her imaginary girlfriend, Skylar used her other hand to reach between her legs and play with her clit. It felt perfect. It felt amazing. Her body was on the edge of orgasm, all she needed was one push. The pleasure built, the pressure kept rising. It had never felt so good to be horny, but no matter how hard she rubbed herself, no matter how heavily she mauled her own tits, and no matter how frantically she fingered her dripping cunt, she could not push past the edge that would grant her release.

“Fuck! Why can’t I cum?” Skylar shouted in frustration in between needy thrusts of her hips, shattering the fantasy.

“Because that’s not going to work, sweetie,” the voice chided once more. “I’m in charge now, and you already know what it is I want. What you need.”

Skylar shook the thought, or voice, or whatever it was, away again and muttered to herself. She’d never had trouble making herself cum before. Edging herself was one thing, but being constantly on the verge of orgasm but being literally unable to get the release was maddening. Her thighs were trembling, her tits were bouncing with every desperate breath, and her pussy was an aching, dripping mess that refused to give her what she needed, but happily ate up every bit of attention it was getting.

An idea formed in her head, and she got up from the bed on shaky legs and lounged in her computer chair, legs spread out wide as she opened up a browser. On the days where Laila’s photos wouldn’t cut it, lesbian porn never failed.

She clicked on the first video she found in the category and let it load, squirming in the chair as she waited, her fat ass spreading farther against the seat and her pussy leaving a wet spot beneath her. Two gorgeous women filled the screen. It was a long video, switching from the pair eating each other out, scissoring, fingering, licking every part of each other in ecstasy. She cranked up the volume and went back to work on her cunt, three fingers a blur as they stretched her tight walls and her thumb rubbed her clit. The thick, curvy body on the screen should have done it for her. It always had before. And it felt amazing, her nerves lighting up like fireworks as her hips bucked and wet, obscene squelching sounds filled the room. But again, the pressure built higher, her pussy clenching and drooling messily down her ass, her heavy tits bouncing as she thrust against her own hand like a desperate slut. Still, there was no release. Just an agonizing, empty ache that made her scream in frustration, her plump lips parted in needy whimpers and cries.

“Fuck… come on…” she chanted in gasps, voice high and breathy. She was right on the edge. Twisting. Writhing. Whimpering desperately to the point she was unaware of half of the things coming out of her mouth.

“FUCK IT!” she cried when her arm finally grew numb and tired. Over half an hour had passed since she had gotten in the chair. She waved her arm around and switched to using her left hand, which was clumsy and barely felt good, but it was enough to keep her level of arousal going. I wanna cum so badly, she thought. I’ve never wanted it this bad…I need to cum, but nothing’s doing it for me! My pussy feels so empty…

As she was about to call the whole thing a wash and let the pill wear off, she went to close the browser, and something in the sidebar caught her eye just as her mouse hovered over the X.

“Cum Compilation 7…” she murmured with mixed emotions. Boy-Skylar had never enjoyed these videos. Maybe it was the fact he could never self-insert as such a dominant man cumming on women’s faces, or maybe it was how close-up the camera always got, but he had always avoided them. Now, however, Girl-Skylar felt a thrumming in her tightening chest that made her lick her lips. 

“That’s what we need right now~” that same, honey-sweet voice whispered through Skylar’s brain. Desperate as she was, Skylar didn’t even react to the sound this time, but clicked on it. The video opened up on a pretty blonde on her knees, her petite throat bulging as a thick cock pumped load after load straight into her stomach. When the man finished, he pulled out violently and let his cum and the girl’s spit drool onto the floor. Then another girl with brown hair this time was sitting patiently with her mouth open as a man jerked off into her mouth until it was filled with pearly white cum. Then a series of creampies as cum leaked from a dozen ruined pussies while the girls on screen moaned like they were in heaven. Music was playing in the background, and Skylar’s fingers sped up to follow the rhythm. Her breath hitched. This…this was it! This was what she needed. This was getting her closer. Her clit throbbed harder. Her pussy fluttered around her fingers at the sight of all that thick, hot cum being pumped and swallowed. She was right there, she knew she was, teetering on the brink of the most intense orgasm she would ever experience.

But she still couldn’t cum.

Come on…please…just a little more…

Then the voice slithered to the front of her mind this time, louder than it had been, like she was whispering into Skylar’s ear. Low and sultry, her voice dripped with wicked amusement.

“Poor thing. All this thick, fuckable meat and you still can’t get off?”

Her hand slowing but not quite stopping, Skylar squinted her eyes in suspicion. “Who are you?”

“My name is Amy…” the voice, Amy, chuckled. “You know what we need, don’t you? Real cum. Hot, thick loads pumped straight down our throat or deep into this greedy cunt. Nothing else is gonna cut it anymore. So how about you pick up the phone and give that stud from your science class a call? I bet he’s packing at least 10–”

Skylar yanked her hand away from her pussy and her nipple as if she’d been burned, sitting up quickly. Her pendulous tits swayed heavily with the motion. Panic cut through the perfume of arousal choking her mind.

Something’s wrong, she muttered to herself and scrambled for the pill bottle. She flipped to the label and her stomach dropped.

Cross-Shift: Cumslut Edition

Doses: 1

Days: 5

There were no other details on the bottle, just those two details and the name of the edition.

“Shit, they sent the wrong one!” Skylar reached for her phone and found the Cross-Shift phone number, and didn’t have to wait too long before being directed to an employee.

A perky voice picked up the line after a short burst of jazz music. “Cross-Shift Customer Service, my name’s Reiley, how can I help you?”

“Hi, My name’s Skylar Olson. I took my Cross-Shift pill a little while ago, and I seem to have gotten the wrong pill. I was supposed to get the regular one, but I got one called Cumslut Edition?” 

Skylar gave Reiley all the ordering information she needed, and the girl’s tone went from perky to disappointed. “Yes, Ms. Olson, there seems to have been a mix-up with most of our shipment last week. We’ve isolated it to a machine sorting malfunction, but unfortunately there is no way for us to know who had been affected by the mistake until they contact us.”

“So you mean I’m like this because of a stupid computer?”

“Yes ma’am. And I’m afraid there’s some bad news, but also some good news. The bad news is that, unlike your usual pill, the Cumslut Edition won’t fade away with time. With the Cumslut Edition, there is a time limit alongside a certain…requirement…you have to meet. There should have been a number on the label of the bottle, and if you allow that amount of time to run out without meeting the requirements, the changes will be permanent.”

Skylar’s mouth felt dry no matter how much she licked her lips. “I’ll be stuck like this? I can’t just take a Male Cross-Shift and turn back?”

“If the changes of the Cumslut Edition are allowed to become permanent, your body will become immune to any other Cross-Shift editions, just like with any possibly permanent Cross-Shift variants. Maybe one day it’ll change, but as of right now, if you don’t fulfill the requirements of the pill, you’ll stay as you are for the rest of your life.”

Oh…oh God…” Skylar gasped in shock. Her body felt numb even as her pussy continued to throb with unmet need.

“Ms. Olson, I am very, deeply sorry for this mix-up, but remember how I said there was good news? If you want to go back to your previous self, all you have to do is do what the pill wants.”

“And what does the pill want?”

“Well, um….” Reiley was stammering, embarrassment clear in her voice. “Well, the pill is called ‘Cumslut,’ ummm…you can probably figure it out from there, right? There’s a bigger pamphlet than usual tucked into the pill bottle. It’s just…kind of embarrassing to talk about with someone over the phone. Anyway, you will, of course, be compensated for the trouble, and I’d be more than happy, if you’d like, to give you as many free Cross-Shifts of any variety you would like once this is over, should you succeed in meeting the quota.”

Skylar hung up the phone. There was little point complaining anymore than she already had. Compensation could come later. For now, she knew that all Cross-Shift would be able to tell her is to ‘do what the pill wants’ if she wanted to go back to being a man. And to figure out what that was, she’d need the pamphlet.

Reiley was right, whereas the typical Cross-Shift pill came with a little card with only the most minimal of instructions on it, this one had been folded over and stuffed into the bottle. How Skylar had failed to notice it, she would never know. Hindsight’s 20-20…

She unfolded the packet and laid on her bed to read it. Her body still buzzed with arousal, and her thighs kept clenching together anxiously as her eyes poured over the words.

“Cross-Shift: Cumslut Edition 

“Embrace the challenge. Live on the edge. Become more.

“Thank you for choosing the Cumslut Edition of Cross-Shift! This is our most intense and immersive temporary* transformation experience. Whether you seek the ultimate thrill, wish to push your limits for a partner, or simply crave a true test of willpower, the Cumslut Edition provides an unparalleled descent into pleasure and submission.

“Important note: Unlike standard Cross-Shift, Cumslut users will not return to their previous selves after the usual 3-5 hours. Reversal is user-driven and requires active fulfillment of conditions set by the Cumslut Variant. Please see below for more details.

• In order to restore the user to their previous self, they must ingest or receive a certain amount of semen within their mouth, vagina or anus within a time limit.
• It does not matter if the donor is a Folk or a human, or a male or those born ‘dual-sex.’ As long as the donor has a penis with working testicles, they are acceptable.
• The number of semen-loads necessary to return to ‘normal’ varies from person to person and is impossible to know. Some may need 5. Others may need hundreds.
• You, however, get to decide on the days when ordering. Check the bottle if you need a reminder! Users are strongly advised to plan ahead of ingesting.
• The semen MUST stay within the user’s stomach, anus or vagina for at least 5 minutes in order for it to count.
• Scooping up semen or ingesting it from other sources does not count, thank our engineers and QA team for that miracle! So no cheating!

“Common Side Effects:

“Users of the Cumslut Edition should expect the following progressive effects. Intensity typically increases throughout the lifetime of the pill:

• Masturbation, lesbian activity, or any other sexual activities that do not involve a fully functioning penis will produce arousal, but will not result in orgasm. Orgasm only becomes temporarily possible after a qualifying semen load has been received.
• Orgasms are intensified, even when compared to typical Cross-Shift experiences.
• A secondary feminine persona may, and often does, emerge to assist with the experience of the Cumslut Edition. Upon successful completion of the quota, the persona will fade.
• Initial cravings center around the taste and sensation of fresh semen. Over time, the user may experience powerful addictive responses to orgasm itself, with each climax reinforcing the desire/need for the next.
• Attraction to women may shift toward viewing them as competition, potential allies in obtaining semen, or objects of worship.
• Extended periods without orgasm (users report ranging from 3-24 hours) can result in significant degradation of impulse control, increased pliability to dominant partners, and heightened desperation.
• With continued progression towards the semen quota, sexual boundaries tend to blur. Users often report growing enjoyment of degradation, objectification, and increasingly extreme acts. The aforementioned feminine persona will guide the user through these experiences.
• Subsequent orgasms typically become easier to achieve, and increase in intensity as well, once the initial orgasm has been achieved. Simple touch may eventually prove sufficient to bring the user to the edge of orgasm, though, as previously stated, they will need to ingest semen in order to be allowed to orgasm.
• Prolonged denial of sexual activity or semen intake will intensify physical and mental cravings, potentially leading to risky or public behavior.

“Warning: Failure to meet the quota within the time limit will result in permanent physiological and psychological changes. These changes are often more pronounced than the temporary* state. Cross-Shift assumes no liability for unintended lifestyle alterations.

“We at Cross-Shift hope you enjoy your journey. Remember: every load brings you closer to who you were…or who you were always meant to be…

“Questions? Contact customer support!

“*- the term temporary applies only to those individuals who successfully meet their quota and return to their previous selves.”

Skylar let the info packet fall onto her chest, the glossy paper sticking slightly to her sweat-slicked skin. Her hands were shaking. Her massive tits rose and fell rapidly as a panic attack loomed, warring with the constant, throbbing heat between her luscious thighs. She should have realized there was something wrong. She should have looked at the bottle, at the thick packet, before taking it. She should have known something was wrong at any point while she was fingering herself. She shouldn’t have kept going, because now she was on the edge and nearly all she could think of was getting release.

There was no antidote. No easy reversal. She had five days, and some unknown number of loads she had to take straight from the source.

She read over the packet again, desperate for some loophole. Her eyes lingered on the lines about the persona, the orgasm dependency, the cravings that could turn her into a ruined mess in public. Her new pussy gave a slow, needy clench at the words, as if the damn thing was anticipating what the paper promised.

This is insane! She thought. I can’t do this. I won’t–

“Yes you will~” Amy’s voice slid through her mind, smooth and warm, far too pleased with herself. “Look how wet you still are, how you’re shaking your hips and clenching your pussy around nothing. Your body already knows what it needs, whether you want it or not…all you have to do is get some cum. You don’t have to like it, and I promise it’ll feel amazing enough to where you might not even hate it entirely…c’mon, you’re letting this perfect body go to waste in this room.

Skylar squeezed her eyes shut, trying to ignore the voice and the way her fat nipples tightened at the thought of dropping to her knees the way she had in her fantasy about Laila. She could still taste the memory of getting fucked. She could feel how close she’d been when she imagined thick cum pumping into her.

She stayed like that for a while, her soft thighs pressed together, one hand unconsciously cupping the heavy underside of her breast, before she forced herself to sit up. The motion made her enormous ass spread against the mattress and sent another trickle of arousal down her skin.

“I have to fix this,” she whispered, voice small and unsteady. “I don’t have a choice.” Because there was no way she could show herself to her sister, her mother and father, and especially not Laila, the way she was.

But even as she said it, her eyes flicked back to the paper, then to her phone, then to the door.

The first step was going to be the hardest.

And the worst part was the tiny, shamefully aroused voice in the back of her head– one that sounded suspiciously like Amy– already wondering how long she could hold out before she lost some part of the old Skylar.

She swallowed hard, thighs clenching again.

She had less than five days.
