Steph was very curious what would happen if she pressed the button. Chris pressed it once she should get a push right? *Thunk* went the button as Steph pressed it, and Chris looked over to see his girlfriend's hand on the button. Then felt a pressure in his crotch. The man felt his little worm grow into a girthy stick. Pretty big to really satisfy Stephanie without being too big to be intimidating.
"By the look on your face did anything change?" Steph asked
"Not something to show off on a first date I dont think..." Chris responded a little bit embarrassed.
"Aw that's no fun after you get to see something of me." *Thunk* Stephanie pressed the button again, and this time Chris' clothes got tighter across his body as he got bigger and bulkier as he started looking more like a weightlifter. Then his own clothes adjusted.
"Hey I only got one" Chris said and then his hand came down and *Thunk* Steph tried looking at her breasts to see if they'd swell or grow more. Her body didn't change though instead of her dress and bra covering her breasts all that covered them was a blanket. She felt a nice mattress on her back, and turning to her side was a naked, buff, and big man she recognized as the newly changed Chris. Looking downward to the sheets a bit lower down at his body there seemed to be a bit of a teepee going on. The two were breathing heavily as their bodies started aching for sex, and made a mess of whatever bed they were in.
