Blond hair on his shoulders, make up on his face, tits on his chest, and a pussy between his legs. It was hard not to think about as Collin stood outside the dorms and he felt terribly nervous. Not because it was strange to be a young woman, but because it was becoming terribly familiar...
=====
Collin was supposed to be a man. He was supposed to be almost three times the age he was now.
Collin and his coworkers had been working on the PRX7Q - name to come - a device that would allow someone to radically alter their body. All they'd managed was to change someone's hair color, which was not a good use for a device that had cost hundreds of millions to develop. They'd gotten stuck there, and a lot of the lab had been let go. Collin had pressed on, working late into the night, trying to find a more useful "app" - youth. He eventually had a breakthrough and decided to test it on himself.
That was when he learned there was a catch. The various parameters for the youth setting had side-effects and could only produce a female body.
Finding himself suddenly a young woman who looked like she couldn't even buy alcohol instead of being an old dude pushing sixty had been a bit of a shock to say the least. He suddenly felt so good! He felt so energetic and alive! He knew the effect was totally reversible, so he wanted to go out and celebrate!
He tried a bar, but they wouldn't sell him alcohol. Fortunately there was a college campus nearby, and it was easy to find a party on a Friday night.
It was fun, pretending to be a student and hanging out with other young people. The booze really hit Collin in his tiny woman's body though, and he didn't even notice how much until he found himself on a touch getting aggressively petted by another student. That touch lit Collin up. He knew he should've said something and stopped it, but his whole body was burning with need. By the time the guy asked to go back to his dorm room, the mix of arousal and alcohol left him utterly unable to say no.
After losing his womanly virginity in some shockingly enjoyable sex, Collin had sobered up enough to know he needed to turn back, so he snuck back to the lab and did just that.
Because of the layoffs at the lab, it wasn't totally clear to Collin who he should report his breakthrough to. He knew he had a bug to fix though. He needed to be able to make someone young without turning them into a young woman, even if the sex was great that way.
A week went by and Collin made no progress. He felt tired and frustrated and achy and old. He felt he deserved a break, and the siren song of the device was just too tempting. He turned himself into a young woman again. A young woman who found her way back to those dorms...
=====
Tonight was going to be different, Collin told himself. Tonight was going to be the last night. He knew he was getting hooked on this feeling. He'd made no progress at work, where he spend an increasing amount of time fantasizing about Fridays...
It been months since then, and Collin had found himself turning back into a young woman every Friday since. It was addictive: being so young and energetic. It was addictive: having a dick shoved into your pussy over and over again until you could only cry out in pleasure. Tonight would be the final tour of "Collete", then stopping cold turkey. They'd finally sorted things out in the lab and Collin had a real boss again, but he'd kept his breakthrough a secret so far. After tonight he'd come clean and let the chips fall where they may. Even with the side-effect of feminization, the device's ability to give someone back their youth would be incredibly valuable.
In the dorm party, Collin let the future go and felt light and carefree, as only a young person truly could. Collin caught sight of a young man he'd seen watching him at the last couple parties and decided tonight would be that lucky young man's night.
Pulled into an empty dorm room, the young man fucked Collin and it was incredible. As Collin moved onto all fours as the young man took him from behind, Collin could feel his orgasm rising.
"Damn Collin. You really are a slut like this." The young man said. It took Collin a second to realize he'd been called by his real name, not "Colette".
"What- FUCK!- I-" Collin was still on the edge of orgasm, despite starting to panic.
"I'm not surprised you don't recognize me. I discovered this little secret - your breakthrough - while snooping through your files. I even came up with a fix for your little "bug" and got it so I could stay a guy after gaining back thirty plus years of life. God, it's awesome to be this young again, isn't it!?" He laughed and continued to fuck Collin.
"YES! Unggh- boss?" Collin recognized the way the guy talked. His new boss. He was technically savvy, but more interested in slashing budgets and producing breakthroughs.
"You kept this secret from the company Collin. That's no good. Now nobody knows you did this. And nobody is going to know either. You're fired Collin."
"FUCK! OH!-" Collin gasped, "You're leaving me like this?!"
"Call it severance since it's clearly something you want so badly. I followed you to four parties and saw you slink off with a different guy at each of them. Hell I'll even pull some strings and get you admitted here as a real student. But your discovery - it's mine now."
"You can't! I'm not supposed to- UNNGH!" Collin's heart was pounding and not just from the sex. Despite it all, he couldn't de-escalate his rush to orgasm.
"Don't worry. After you graduate I'm sure you can apply for an internship at our company. Unless you get pregnant, which... UUNNGGH!"
**SPLRTT!**
It was so visceral, Collin could almost hear his boss's balls emptying inside of him. The twitching cock pushed him over the edge, and Collin's eyes went wide as a confused orgasm crashed upon him.
"You are an incredible slut Collin." His boss said afterwards, "Good luck!"

Tonight was not his last night, but his first truly being a woman. "Colette" was there to stay.
