Derek had just found a new plugin for his twitch account, and added it right away in hopes of enticing more viewers to donate.

The plug-in was called Xchange, and the description promised to set up custom payment portals to lure viewers in. Derek set it up and started broadcasting his game, watching the donation counter out of the corner of his eye.

After half of an hour without a single donation, Derek was starting to give up hope when he heard a ding. He looked to his screen and saw ‘$5 to legs’, “Five dollars to legs?”

He felt a slight pulsing and looked down, to see his legs were a bit more slim than before.

“Wait…”

Another donation, this time ‘$15 to ass’. Derek felt himself lift a bit in his seat, and knew what was going on. Before he could do anything, a stream of donations came in quickly.

‘$20 to face’

‘$10 to lips’

‘$35 to chest’

With each donation, Derek felt his body change. The more money the more intense, and each one shrinking his overall stature little by little. His face sharpened intensely for twenty bucks, and then his lips plumped up for ten. Derek prepared himself for the monumental thirty five dollar donation to his chest, moaning in ecstasy as his breasts bubbled with fat. He stared wide eyed as his nipples became tender and sensitive, spreading wider than before on his supple A cups.

Soon Derek noticed a bar at the bottom of the screen filling up as each donation came in, it seemed to have a goal to be filled to two hundred dollars. Derek had no idea what ‘$200 goal for all new change options!’ meant, but knew it couldn’t be good for him.

More donations came in, and started coming in larger amounts as Derek became more feminine looking.

‘$70 to stomach’

‘$40 to eyes’

‘$25 to hips’

Soon the bar filled up, and a little pair of panties shot out from the computer. He felt his penis, erect from his sensitive nipples and wide hips, start to shrink. Very quickly it drew into his body, leaving a warm, moist slit.

Looking down he saw he was now naked, and put the panties on without hesitation. The chat went crazy once Derek stood tall with his panties, giggling from the rush of emotions he felt.

He tied them up around his waist, while more donations came in.

His stomach was still toning as new donations came in, now with more mental aspects than Derek remembered. The bar was now half full, with a new goal of seven hundred dollars.

There were comments asking him to play with his tits for donations, but Derek was too embarrassed to give in to that.

‘$50 to hair’

‘$50 to voice’

‘$50 to chest’

‘$100 to face’

‘$100 to style’

‘$150 to libido’

The bar quickly filled up, and Derek felt the changes overcome him. Each one more intense than the last, as his entire body became sexier. His hair became wavy and blonde as his lust filled moans became increasingly sexier, and more fat swelled into his growing boobs.

His face tightened as he felt makeup applied, and a choker wrap around his neck. A tingling started in his pussy, and then intensified a hundred fold instantly.

He convulsed on the couch, screaming in ecstasy as he reached the brink of orgasm. Finally he got used to his new sex drive, and was able to sit down without his pussy rubbing against something and cumming.

“What more could these people do?!?”

They did what we would all do, and donated to the cause!

‘$300 to chest’

‘$100 to age’’

‘$250 to eyes’

‘$100 to chest’

‘$50 to memory’

‘$100 to libido’

‘$100 to inhibitions’

As more donations rolled in, Derek could see even more new change options he hadn’t seen before. His tits swelled and started to hang off his chest, til he aged back a few years per the user’s request.

He felt his eyes grow large and almond shaped while he checked out his new boobs, cupping a breast in his hand to see just how much it had grown as his boobs continued to grow even more. The tissue and fat in them becoming even more sensitive than before as Derek read the comments aloud, “Where do I live?

…

Huh, I can’t remember.

What's my name?

Like, I think it’s Derla… no that doesn’t make sense…”

Derek felt even more horny, and started performing for the chat.

“Play with my boobs?

Sure!!”

As Derek played with his breasts, more people made donations. The bar was now labeled ‘Biggest donation picks name at $5,000’.

There was just over seventeen hundred dollars donated already, and the bar was quickly filling past that.

‘$300 to libido’

‘$50 to hair’

‘$100 to age’

‘$200 to face’

‘$100 to lips’

‘$150 to body art’

‘$800 to chest’

‘$200 to voice’

‘$350 to inhibitions’

‘$200 to style’

‘$50 to piercings’

‘$150 to libido’

‘$650 to memory’

‘$150 to legs’

Derek felt arousal take over his body, and emptiness consumed him as the craving to be filled took over his thoughts. Then his hair tied back into a sexy pigtail, and became sheer black. Each user on Xchange had a donation preference, so some of the changes varied.

This was made clear to Derek as the donation to his age made him almost twice as old, which was especially surprising when you consider he thought he’d get even younger somehow!

Derek felt his cheekbones rise up as his face became even sexier, making his plumping lips take on a permanent pout.

A stinging sensation ran across Derek's body as sexy tattoos accented his voluptuous body, his boobs doubled in size and got even more sensitive as his nipples tingled. The feeling of his boobs growing so much so fast was too much for Derek, and he had to lay back moaning as his voice took a much more luscious and sexual tone.

Derek started giggling and chastising the chat upon request, pretending to be a naughty stepmom walking in on her son masturbating via zoom. His choker came back, and grew out cold tendrils across Derek’s sensitive skin. The lipstick smeared in layers on his puffed lips paled, and round glasses formed around his face.

Derek squealed as studs pierced through both nipples, the stinging pain ending off with intense ecstasy. He felt even more horny, but was too busy trying to remember basic facts about his life and day.

“Like, wasn’t I putting on makeup?

… No wait… I totally can’t…

Video games??”

Derek’s sexy voice was even turning himself on, but he couldn’t remember what he was supposed to be doing…

He felt his legs grow long and slim, before stockings wrapped around them. He saw that the guy who had donated to his chest changed his name to Molly, and then realized his video game controller had become a vibrator!!

Molly grabbed the vibrator and turned it straight to the highest setting, before trying to penetrate herself with it. The bulb was too big, but the deeper she got the more intense it felt. She finally found her sweet spot and pressured it for several minutes, the heavy duty toy vibrating her insides.

More donations came in as her orgasm built up, and she was already feeling the effects when she sprayed cum all over the camera lense.

A new label came up for the bar; ‘Address revealed to highest bidder when final goal is reached: $10,000’

The bar quickly filled again with even bigger donations than before, while Molly masturbated blissfully ignorant of the stream.

Each donation hit as she pleasured herself, too turned on to stop the constant multiple orgasms.

‘$650 to weight gain’

‘$900 to race change’

‘$1,000 to libido

‘$1,200 to chest’

‘$500 to libido’

‘$3,000 to memory’

The last two donations came from the same guy, wanting to spice Molly up before he showed up to her house.

Fat surged through her entire body, forming from nothing and filling out her figure even more than before. Then her skin tone became much darker, and she felt her face change a bit as more fat began to surge up toward her chest.

Then her boobs tripled in size!

No longer able to naturally float on Molly’s chest, and flopping about wildly now, as massive boobs do. She didn’t even notice the arousal spike, but dropped the vibrator from the sudden loss of memories.

All she knew was her name was Molly, she was horny, and there was a vibrator right there on the floor.

She continued her show, when a knock on the door startled her. She bounced her way over to the door, and opened it completely naked.

“Hey Molly…”

The largest donator had arrived pretty quick, and for good reason. Before Molly could say a word, he grabbed her and threw her down on the couch.

“Thanks big boy, I’ve been like, totally craving a cock for hours!” Molly spread her legs, wrapping an arm around her thigh to get comfortable.

The stranger couldn’t help but enjoy the sight for a moment before slipping into Molly’s folds, eliciting squeals of delight from her.

The boob jiggling in her face turned her on even more as a large man thrust in and out of her, reaching parts of her anatomy she had never felt touched in her entire life. They continued in this position for several minutes, then Molly got up and let the stranger sit before getting in his lap.

She plunged herself down his cock, and bounced herself cup and down as he thrust.

Molly could feel twitching, and knew the stranger was close to cumming. She wanted to plant herself down, but he had other plans.

“Quick, sit down on the couch!!”

Something in Molly didn’t even let her think about disobeying, and she calmly got up before sitting next to the stranger. He jumped up and gave his cock a few pumps inches from Molly’s face, telling her to sit still as she reached for his dick with her mouth.

“Now jiggle those magnificent titties”

Molly whimpered orgasmically as the stranger shot his warm load into her cleavage, shaking and turning her boobs so it could get on her nipples too. The warm cum felt amazing on her sensitive skin, and she basked in the glow as her tits glazed over.

“Promise next time you’ll come inside me?”
