Kristen thought she'd lost a friend forever. She'd been caught cheating with her best friend Mary's boyfriend. Of course there was the initial blow out arguments and Mary claiming she'd never forgive them, but it was about 6 months later and Mary had contacted her.
The machine hummed to life. She closed her eyes and waited for the changes to occur. However, something felt off. She expected to feel lighter or stronger, but with each change she began to feel more bloated and sluggish.
She opened her eyes and looked down in horror at the changes overcoming her.
First she noticed her hands, huge, ridiculous acryllic nails had appeared. She knew Mark hated them. And then she noticed the rest. Her previously perky, if small, tits had grown several cup sizes, but also now sagged down her chest. In between her cleavage, she saw paunchy belly, her stomach now flabby and soft. She awkwardly angled herself, and noticed her tight inviting slit was now a flabby, fat pussy, sat in between thick, jiggling thighs.
The humming stopped, and the door opened to reveal Mary, laughing hysterically
"Oh my god, I can't believe you fell it for it. Now we're even you bitch."
Kristen took a few uneasy steps, not used to the extra weight, and then stumbled, falling against the changing room corner.
She wasn't hideous, some would even find her hot, but she knew Mark would hate absolutely everything about her new body. He was never shy to say what he didn't find attractive.
She regained her composure, and stood back up. Mary had at least left her some clothes. She changed and went to the front desk. Begging and pleading with the receptionist, who could only refer to the contract
"Please change me back"
"Again Miss, I'm afraid all swaps must remain at least 12 hours to fulfil your rental obligations. And we close in 6."
She finally gave up, leaving the clinic. She walked to her car, hating how her new body jiggled and shifted, and there was something else. There was a familiar warmth in her crotch. She was horny. But this felt more intense, more insistent than usual.
Her clothes rubbing her nipples already had her heavily breathing, and by the time she'd got the car she simply had to service herself. She awkwardly tried to find a comfortable position in the car, she struggled to get a good angle on her new body, and simply undressed
As she cracked open her thighs an unfamiliar and unpleasant smell drifted into her nostrils, she smelt like she barely washed and sweated far too often. She forced through it, for some reason her new pussy felt even better than her older one.
With enough work, she came to a roaring climax right in the parking lot.
The urges that'd clouded her mind passed, and she felt ashamed as she stared at the damp spot on her car seat, and the fact she hadn't checked if anyone was watching.
Kristen returned home, and waited for her boyfriend. In the intervening hours, that same wave of horniness had come on at least 3 times and she was happy to satisfy. Mary must've thrown ramped up horniness into the mix.
Her boyfriend was obviously shocked by his girlfriends new appearance, not even managing to hide his disgust at the change. However he was calmed when she explained it was simply for the night.
He was less calmed when she'd been fidgeting in her seat and eyeing his crotch all night
"No" He said
"P-mmh-please" She begged
"I don't know if I could get it up"
"I can help" She said, and tried to seductively slink over, looking outright ridiculous, unable to use her body properly.
Mark's claims drifted away pretty quickly once she'd got his trousers off, and was slurping away on his cock. He closed his eyes and thought of her old body while she sucked and fingered herself.
In the afterglow, Mark wondered if maybe this version of his girlfriend wasn't all bad.
After finally relieving herself, Kristen was happy to go to bed early.
She woke up before her boyfriend, and tiptoed out the room. She didn't want him to have any lasting memories of her like this. She arrived at the swap clinic just as it was opening. By now the yearning need in between her thighs was almost unbearable, but she knew it would go when she got the swap done.
The woman behind the desk found her details, and raised an eyebrow.
"Are you sure you don't want to double check the con-"
"N-hnn-no. No. Just get it done" Kristen begged
The woman shrugged and lead her to the changing pod. On the bench outside she found a pile of clothes that looked in her normal size and a note. She ignored them, desperate to get out of this form.
The pod hummed into action, and she closed her eyes as she felt the weight lift off her. She felt her tits stop sagging against her chest, as she touched them, she realised her absurd nails were gone as well. She brushed her hands down her changing body, a tight stomach returning, shapely thighs. She felt a bit concerned that the horniness hadn't lifted, but suddenly it disappeared. She sighed in relief, but a second later, a similar but alien feeling was back.
Her wandering hands moved to her crotch, and she screamed in surprise. Instead of her old tight slit, she had a raging hard on
The pod dinged as the shift finished, and she saw herself in the full length mirror
How... how had this happened? Not only did she have a cock, her entire appearance had changed. Dyed hair, a more nerdy face, very pale. Tears began forming, she remembered Mark stating how much he hated pretty much everything she was now
She remembered the note, and picked it up
"Hey Kristen,
If you're reading this, you're a bigger idiot that I thought.
I arranged the swap so afterwards, you'd look like you do now. And it means you didn't check the clause that bars you from using the swap clinic ever again.
Of course I'd never forgive you, you bitch. You were my best friend, and you stole my future husband. I know Mark didn't like goths, but I figured I'd be 100% sure, I know for a fact he doesn't like cock.
But don't worry, you'll still have fun, I made sure they left your elevated lust in there
Bye Forever,
Mary"
Kristen fully broke down. She'd had everything taken from her in a mere 2 days. Just for the simple act of cheating.
After she'd finally had some time to collect herself, Kristen realised she had to get home to process this more. She pulled on the pile of clothes, and noticed Mary's final prank.
She picked up a leaflet and covered herself, awkwardly walking back to the car. Pressing something after her cock was driving her mind into overdrive. She drove home as fast as she could, and rushed to the bedroom.
She was so focused on the task at hand, she didn't even hear the noises of the shower, the shocked yelp, "I'm done", and the door slamming as Mark left her. For now, she was focused on only one thing, and it felt great.
