The Gym – A Tumblr Rewrite

Models: Alyssa Reece, Amirah Adara, Honey Demon & Veronica Leal


Waiting for the penny to drop was undoubtedly the best part. Toni knew exactly what was about to happen – not to mention what sordid scenes the night would spiral into once her revenge took effect – yet none of those pleasures could hold a candle to the wicked thrill she felt when the three hunky gym bros realised what she had done to them.

Milo was the first to notice something was wrong. Toni had expected as much: he always was the smartest of the trio. Stood in the central boxing ring he stumbled slightly, bracing himself against the padded rope. A frown passed over his handsome features as his hand began to shake. Toni could practically see him slot the pieces together.

‘She… she’s drugged us,’ Milo said, his gaze snapping up to meet the petite beauty.

Leaning against the stall bar Toni fought down a grin. After several hours of working out her tanned body was glistening with perspiration while her hair was slicked back tight to her scalp, the dark roots giving way to bleached ends. Her grey sports bra and loose shorts emphasised her lithe figure and she could see in Milo’s eyes that despite his growing unease he still couldn’t help but crave her. But it was that pathetically predictable lust that had made the trio so easy to manipulate in the first place.

‘What do you mean?’ Felix said from the other side of the ring. Toni rolled her eyes: the dumb bull was just as oblivious as ever. Still, he’d barely finished the question when he was forced to lean against the corner post as his knees threatened to give way beneath him. ‘Oh… that’s what you mean.’

While Felix’s response was confusion, and Milo expression was a mixture of disbelief and betrayal, the third man in the room jumped straight to rage.

‘You bitch,’ Drake spat, his eyes ablaze as he stormed towards her. But two steps in his legs buckled and he had to cling to another stall bar to remain upright. ‘Who the fuck do you think you are? Do you have any idea who you’re fucking with?’

‘Yes, she does.’ Milo’s voice was quiet, his eyes turned to the floor. He had slumped to his knees now. ‘Haven’t you worked it out yet, moron? Her name’s Toni.’

‘Yeah, so?’ Drake barked.

To Toni’s surprise Milo gave a short laugh before lifting his gaze to meet hers once more. ‘It’s short for Anthony.’

Drake’s fury vanished instantly. In its place his face twisted with raw shock. Skin ghostly pale, eyes wide, jaw on the floor, it was the kind of image Toni would have gladly framed. In truth that sight alone marked the completion of her revenge: all she’d wanted was to see the look on Drake’s face when she turned the tables on him. Nevertheless, she had no intention of leaving now. After all, why would she settle for comeuppance when she could humiliate them too?

Toni had been dreaming of her revenge for weeks. But the scene that followed was more delicious than she had ever imagined.

Although Milo had been the one to sense Toni’s trickery taking hold, Felix was the first to display any physical effects.

In the otherwise deserted gym the creak of shifting bones was clearly audible. Leaning against the ropes of the ring he grunted more with surprise than pain, and his hands were surprisingly settled despite the fact he was steadily shrinking. His torso was the most obvious victim, contracting gradually until his burly, slab-shouldered frame had halved in width, though the same reduction was happening all over his body. His arms, his abs, his shins, everything diminished, the bulging muscles he had spent years building simply melting away like a frost at dawn.

The physique they left behind was both athletic and sultry. Like the others Felix had worked up a healthy sweat during their workout, and as his body hair receded this gave his smooth flesh a sheen that subtly highlighted his curvy new figure. Though not as tanned as the hue provided by Toni’s Colombian blood, Felix’s skin had an undeniably sun-kissed glow – and the longer his transformation continued, the more skin was on show.

Every time Toni had ever seen Felix he was always clad in tank top and shorts. Today they were both black and as Toni watched they came under attack. The hem of his baggy shorts rose rapidly, only stopping when they had crowned the curve of his hipbones and were nestled between his ass cheeks in a manner more akin to a thong than any sportswear. His newly plumped ass was on full display within seconds, while higher up his tank top had undergone a similarly revealing reformation. Where once only his arms were visible, now a tight sports bra exposed most of his torso as well as an enticing dose of cleavage.

Throughout the transformation Felix’s head had been turned away from Toni, but as the effects settled and he steadied his shuddering hands on the perimeter ropes, the ex-hunk finally turned to face her. The sight sent deviant delight thrilling through her system. His dumb, block-shaped face had given way to beguiling beauty. Sharp brows, soft cheeks and a delicate jawline gave the new woman an enchanting aura, the dark hair that had sprouted from Felix’s scalp pulled back into a pair of tight plaits bound by neon yellow scrunchies.

Unable to contain her glee, Toni bounced giddily on the spot. True, Drake had been the main target of her revenge, but Felix was undoubtedly second in line.

The day the trio of gym bros had approached Anthony felt like a lifetime ago, but Toni remembered Felix’s stupid grin as if it were yesterday. Subtlety was not a skill he possessed and as such he hadn’t been able to keep a straight face once during their ‘prank’.

‘They’re stamina boosters,’ Drake had lied, offering Anthony a strip of garishly pink pills. ‘Honestly, these things are the real deal. Just one will keep you going all night long. They’re perfect for an energetic session.’

To his credit, Drake had sounded convincingly sincere, but every sentence was punctuated by Felix’s sniggers. Still, Anthony hadn’t thought much of it: after all, Felix laughed at anything, even jokes made at his own expense, and like everybody else Anthony had learned to tune him out.

Unfortunately, by the time Anthony had realised just how big a red flag Felix’s amusement really was it had already been far too late.

While Felix stared at his new body in dumbfounded amazement, Toni turned her attention to Milo on the other side of the ring. He was still on his knees and gasping as his transformation kicked in, but unlike the other two he didn’t seem to make any attempt to resist the effects. On the contrary, he simply closed his eyes and allowed them to consume him.

In Milo’s case his clothes were the first thing to change. The cuffs of his jogging bottoms had much further to rise than Felix’s shorts, and as they ascended the threads shifted from basic beige cotton to dappled grey spandex edged with hot pink seams that would soon emphasise his developing curves. His long-sleeve compression shirt shrank just as quickly, the dark grey material steadily paling as it contracted into a small sports bra which eventually settled to a striking coral pink hue.

With his transforming body now on full display, no element of Milo’s metamorphosis was left to the imagination. Starting at his feet and rising to his nape his body hair swiftly withered back. The skin it revealed was temptingly smooth, all the blemishes and scars he had accrued over the years already faded away, though his existing tan persisted throughout the changes to give him a bronze lustre just a few shades lighter than Felix’s. Tendons shifted, muscles softened, and despite having his back to Toni it was clear from the way his hands fell to his crotch that there was no longer any bulge in his shorts.

Milo had always been the leanest of the trio and this trait carried over into his new body too. In fact, compared with Felix far more echoes of Milo’s former appearance bled through despite the feminisation. He was still unrecognisable, but there were faint traces in the lines of his skull and proportions of his frame that could perhaps have convinced an onlooker that this new woman was Milo’s sister. Even so, if anybody had started to piece together the truth they wouldn’t have lasted long, for with a bat of his eyelashes and a flip of his plaits the new Milo would have had them eating out of his palm. If that wasn’t enough, a glimpse of the subtle stretchmarks lining his upper thighs would have made it quite clear that Milo had become the kind of woman whose preferred workout involved bouncing her perfect ass all night long.

The look Milo gave Toni once the changes settled was one of respect. Though he clearly hadn’t expected Anthony to retaliate, he also knew it was entirely justified.

On the day Anthony became a woman, Milo had tried to intervene, even using Anthony’s initial apprehension to try and talk Drake down. ‘Come on man, he doesn’t want your pills. He’s just here to get in better shape, he’s not interested in juicing.’

But Drake was insistent and eventually Milo had stopped protesting and allowed his friend to turn Anthony’s life upside down.

In the days after, Milo tried messaging Anthony countless times. He claimed he had no idea what Drake’s pills really were, and when he realised the truth he was horrified by how far over the line his friend had gone. His consistent attempts at contact had convinced Toni that he was telling the truth, but ultimately that didn’t absolve him. After all, he hadn’t bothered to question Drake’s real motives, nor had he cut ties with the brutish bully in the weeks since.

Yet even if he hadn’t done enough to earn her forgiveness, he had still managed to earn her leniency, which was why she had diluted the effects of his transformation enough to let most of his old psyche survive the transition.

Drake, on the other hand, was afforded no such mercy.

He was still leaning heavily against the stall bar and clearly fighting the corruption in his blood. But the effects were inevitable and all he had achieved was to further work up a sweat, which set his skin glistening as he finally transformed.

Having resisted so hard, when the changes hit they did so hard and fast. Drake let out a howl as his chest inflated rapidly, the chest of his shirt suddenly stretched to its limit by a huge silicone rack. The orgasmic ache of his new bosom drew out a sensual groan, though it was nothing compared to the primal shriek he gave as his cock retracted. The sound hadn’t even reached his lips before his groin sported a tight, throbbing pussy that leeched all the strength from his legs, forcing him to cling desperately to the bars to stop himself crumpling to the floor.

Drake’s tits weren’t the only things inflating. His ass and thighs grew ever fuller, his lips and cheeks were shot with filler, and all the while the impressive physique he was so proud of – rippling biceps, shredded abs, legs like concrete pillars – simply evaporated before Toni’s delighted eyes. His numerous tattoos were stripped away, while his vainly tended quiff was likewise obliterated by lengths of ink black hair which burst into being and wound themselves into a single plait that whipped about as he writhed. 

Whereas his friends’ clothes had simply contracted, Drake’s went one step further by fusing together. As the matching set of shirt and shorts gave way to black spandex, the two items stitched themselves together before shrinking to fit his voluptuous new figure even more tightly than before. By the time they settled the low neckline boasted a ravine of cleavage, the tight material hugged his plastic curves, and the rump of the bodysuit slotted so deep between his ass cheeks it was lost to view.

When the transformation released its grip Drake’s old body was a distant memory. Where once had stood a beefy gym bro, now there was a glistening silicone-stuffed bimbo seemingly tailormade to pump cock rather than iron.

The grin on Toni’s face when Drake finally met her gaze was nothing short of deranged.

She could still remember the way Drake’s act had broken the moment Anthony swallowed one of the pills, his sincere expression crumpling into sneering laughter. Ironically he’d been forced to support himself on the very same stall bar he’d just transformed against to stay upright.

‘What the fuck did you give him?’ Milo had shouted, shaking Drake by the shoulders as Anthony’s muscles began to clench.

‘X-Change pills,’ Drake wheezed while wiping away tears and clutching his stomach. ‘X-Change Lock, to be precise.’

‘You lying son of a…’ Anthony tried, though the spreading pleasure robbed the end of his sentence.

‘Hey man, I never actually lied. They’ll definitely keep you going all night long – I just might have failed to mention exactly what you’ll be doing during that ‘energetic session’. My bad. Oh, don’t run off, I was looking forward to watching the show.’

But Anthony was already gone. With Felix and Drake’s laughter echoing after him he sprinted from the gym, exploiting the transformative adrenaline coursing through his veins to make it back to his car before the pill’s effects properly kicked in. Reeling with a potent blend of shock and pleasure he had passed out on the back seat, and though he came to his senses less than a minute later by that time he wasn’t Anthony anymore.

Still, it turned out that transforming against his will in his car had a silver lining: none of the gym bros knew what Toni looked like. As such, when it came time to enact her revenge she had the perfect disguise.

‘How did you do it?’ Milo was on his feet now, albeit leaning heavily against the perimeter ropes.

‘Nanites,’ Toni shrugged. ‘You three were all so busy trying to impress me it was almost too easy to slip a dose into each of your water bottles. I knew you liked to work out late, so I set them to activate at a time when nobody else would be around.’ Toni nodded towards the other two women. ‘And as I’m sure you’ve figured out, your nanites weren’t quite as potent as theirs.’

Felix was still staring down at his new body with an expression somewhere between shock and confusion, as if he knew he should be surprised by this development but wasn’t quite sure why. As for Drake, he was glaring daggers at Toni, yet behind the fury was a rapidly mounting lust.

‘Why not?’ Milo asked.

As Toni spoke she began to peel off her clothing. ‘Call it a thank you. See I would never have transformed by choice, but I’ve come to realise that this body has its perks. And since I never would have wound up this way if you hadn’t done such a piss poor job of defending me against the cunts you call friends, I figure I have you to thank for that. Of course, I couldn’t let you off the hook completely – an eye for an eye and all that. The nanite transformation is irreversible. But whereas you’re in control of your body, those two… well, let me show you.’

With her sportswear in a heap on the floor, Toni strode naked into the boxing ring. Stood against one of the corner posts she raised her feet onto the middle rope while gripping the upper one to stabilise herself. Despite the exertion her lithe, shiny body held her steady with ease.

Only once in position did she turn her attention to Drake. ‘Come on, Daniela. I want to see how well my new pet’s tongue worships pussy. And take that bodysuit off while you’re at it. You’re my plaything now, so from now on I’ll decide what you’re allowed to wear.’

To Milo’s astonishment, his former friend did not hesitate. Whatever coding was in the nanites it had forced Daniela completely under Toni’s thrall and she obeyed her commands without question. In less than a minute she had stripped naked and was squatting beneath Toni’s hips feasting ravenously on her twinkling sex. By now any lingering animosity had dissolved, and if the enthusiasm of Daniela’s lapping tongue was any indication she no longer remembered anything of her old life. She was simply an obedient bimbo eager to serve the whims of the vengeful slut she had foolishly created.

Savouring her victory Toni closed her eyes and groaned as she allowed the pleasure to wash through her.

When she addressed Felix she did so without opening her eyes. ‘I think our friend here looks like she needs some personal attention, don’t you Felicia? How about you come and join Daniela, there’s a good girl.’

Felicia responded a little slower – clearly the transformation hadn’t erased Felix’s stupidity – but soon enough she was also on the floor, mirroring Daniela’s stance almost perfectly with her mouth open and tongue out ready to fulfil her orders. The sight set Milo’s new pussy quivering, the urges of his feminised body imploring him to make use of Felicia’s waiting tongue.

Unable to resist he was already stripping off and crossing the ring when Toni fixed him with a deviant smile. ‘Don’t worry, Mila, you’re going to enjoy being a gym bunny, I guarantee it.’ Reaching across she patted the rope above Felicia. ‘Come on, bestie, let me show you the ropes…’


Thanks for reading!

One of the things I’ve noticed when working on my Tumblr rewrites is that these days my stories include far fewer ‘on-screen’ transformations than they used to back in the day. There are certain exceptions – my longform Fantasy Universe stories always include at least one transformation, for example – but on the whole I’d say the balance has definitely tipped away from such scenes over the years. Even stories that do include gender swaps don’t always involve physical changes: bodyhopping, body swapping, merging and possession can all involve one character experiencing the body of another, yet at no point do they actually undergo physical transform.

From my perspective that’s not necessarily a bad thing. One of the things I love exploring the most in my work is how characters react to their transformations hours or weeks or years after the fact. Not only does it pose a challenge for me to write a character who has been drastically changed by their experiences, but it also allows me to use the transformation as stone one to then build on, rather than as a crescendo.

At the same time I’m aware that transformations are what my blog was founded on and are what many TG erotica fans enjoy reading the most. So when it came to this one I decided I wanted to go all out with the transformations. I was especially inspired to do so given that all four models had their own solo shots, which meant I could devote a section exclusively to each of them including a dedicated supporting image rather than taking a group image and trying to pick each character out one by one.

Overall, I really enjoyed the experience of writing this, and though it is very different from the Tumblr original I also think it is vastly superior. Ultimately, I don’t know if the trend of my stories being set post-transformation will continue as every story is different, but if it does then rest assured whenever opportunities to go transformation wild like this present themselves I will be sure to take them.

I’d also be curious to know what my readers think on this subject. Do you like transformations to happen within the story, or do you prefer reading the consequences of those transformations?

Finally, next week marks the beginning of my 2025 Gaypril slate. I’ll be honest I had no idea whether or not I wanted to do Gaypril this year until very recently, but I’ve managed to put together enough stories to do so and honestly I’m pretty pleased with the results. I know not everybody in my readership is a fan of my gay content and that’s fine, so if that’s you then I hope you’ll return in May once I’m back to my normal more female-centric stories. But if you do like my gay stuff then I look forward to seeing you next week for a visit to a very steamy sorority…
