A couple of minutes pass and the screen Jeff was looking at lights up with the phrase "transformation completed". The chronivac's door slides open and out of the clearing smoke comes out not the slim, blonde, scantly dressed beautiful young woman who had entered the machine, but a confused looking, fresh faced teenage boy dressed in a school uniform.
"That was... weird... Did this thing work? I..." The boy who used to bč Jenny speaks. "Woah, my voice!?" He gasps and feels his throat with one hand, finding a bump on it. An adam's apple?? Jeff smiles as he notices the boy's voice was basically still his girlfriends, only it sounded younger and, well, decidedly boyish. He loved it!
"Jeff? I feel weird, I don't... What am I wearing?" Jenny spoke frantically but Jeff quickly came over and gently took her/his hand. "Shh! Come, see for yourself" he told the confused teen and he took him to the full length mirror in the hallway. Jenny let out a horrified and startled gasp as she/he was met with her/his reflection. Mouth agape, she/he examined the Image in the mirror.
That was indeed an adam's apple she felt there, for there's no mistaking now, she's definitely become a male! The boy in the mirror looked quite young, had a sturdy athletic build, short, messy blonde hair and bit of teen facial scruff on his face. He was apparently dressed in a school uniform which consisted of black shoes, dark blue slacks, a white long sleeved shirt and a striped tie, blue and white, with the small Insignia of a school pinned on the knot. Jenny notices the face. It wasn't really obvious with such a change, but it was basically still her own face! Same traits, same green eyes, blonde hair and everything, just...younger and decidedly male. It's what she'd look like if she were a fourteen year old boy! She reaches to touch and feel her face and thinks how strange but also fascinating it was, how only Age and gender could make such a colossal difference to the very same face!
Smiling, Jeff comes closer from behind and puts his hand on the shorter boy's shoulders. "So. What do you say? Believer me now? Told ya the chronivac works!"
Jenny doesnt look away from the mirror, finding the image of Jeff slowly caressing the shoulders of this schoolboy and smiling wide, pretty unnerving. "Yeah...It works allright. I can't really deny it changed me, hahaha..."
"So what do you think?" Jeff asks.
"About what? It definitely works, I..."
"No no, I mean what do you think about, y'know, the new you?"
There is a moment of uncomfortable silence.
"I... Well, I dunno, it's disturbing. Look at me, I'm a teen schoolboy...haha I mean I probably even have a... That's... Weird."
"A penis you mean? Well yeah of course you have a dick, hahaha, testicles too, y'know, like all boys have!"
"But why Jeff? I mean I don't get it? Why'd you change me into a boy? I mean I thought for sure you'd want to make me into something sexy, some sex fantasy of yours... This is weird!"
Jeff makes a warm smile. "Well, Jenny, if you really wanna know, I personally think you look pretty darn good...like this!" And he turns the new boy around, pulling him by the necktie into a kiss, his hands caressing the boy's closely buzzed nape.
After a couple of seconds Jenny pushes Jeff away. "Stop! Jeff what are you doing?! I'm a... I mean, I... This is gay! Isn't it?..."
Jeff lets out a chuckle. "Haha what do you mean what am I doing? I'm kissing you, handsome! And you're damn right it's gay, isn't that cool?"
"Cool? Jeff no this is NOT cool at all, I don't like this, I'm a 25 year old woman, I don't want to be a teen boy, and I don't want to be gay! Lets change me back please, the demonstration is over, the machine works ok? Now please change me back to myself Jeff please!..."
Jeff shushed her with a finger on the lips and with his right hand reached for her crotch. Through the smooth slacks he could already feel the beginning of an erection... He grins and he starts to message her cock through the trousers, and feeling it grow in his hand got him hard too.
"Are you sure you don't like this Jen? You sure you wanna change back now? Then what's this right here? Hmm? If you hate this so much why are you getting a hard on?"
"I.. I... Jeff I... No, stop. Please..." Jenny weakly protests trying to fight the arousal.
"Hush, don't fight it. Welcome it. Relax. Feel your raging teenage hormones... Let the testosterone flow through your body and to your head... Your first erection! You're pretty big, I'm proud of you Jenny!! Why do you want to go back to being a girl? Do you really want to lose your new hard cock? Lose this younger, stronger body and the opportunity to go through school again and do something better with your life than working at a night bar? Come on Jenny, or should I say Johnny? Don't be a bad girl, be a good gay boy and cum hard for me!"
