"I want you to wear this!" She held up a skin suit. It's a girl skin. Judging by the black hair and skin color, you assumed it was an asian girl.
"Why do you want me to wear that one?" you asked.
"She's cute," your girlfriend shrugged. "I think it would be funny, seeing you as this small cute girl. Like, she's pretty tiny, look." She held the loose skin in front of her body. It touched the ground, yet only reached your girlfriend's chest. She gave the skin to you. "Put it on now. Do it!"
"Sure, I guess." You grabbed the skin. You found the opening in the back. You decide to start leg first. One at a time, you get both legs into one of the skin's legs. Your legs were way too long. Your crotch were at the torso. "I don't think this is going to fit," you said.
"It's going to fit. It's magic. Of course it's going to fit," your girlfriend said.
You continued on. You bend your back to get your upper torso in, head first. It's completely pitch black, but then you feel the skin shift around you. You feel the legs of the skin lengthening. No, it's you getting shorter. You feel tighten around you, and then you can't feel it at all. You can see again. You see your girlfriend in front of you, looking down on you.
"Omigod, you're so cute," your girlfriend gushed. "And also," she went behind you, then placed a hand on your new boob, and cupped it. "You're pretty hot too. How does it feel being a woman?"
"Stop it!" you yelped in a tiny sweet voice.
"Hihi," your girlfriend giggled. "This is wack. Can't believe it's you inside there. Like, the voice too, almost like an anime girl. Oh, say something in japanese!"
"Uhm, I don't know." Your girlfriend was more into anime than you, but you were at least familiar with the surface of anime and other japanese stuff. "Kawaii desu ne," you said to humor her.
"Eh," your girlfriend was disappointed. "You just sound like any other american weeb."
"What did you expect?" you ask.
"I don't know, but with you looking like that, it just made me believe you could do it. I guess I believed too much. I guess I just have to settle with playing with my cute litte asian girlfriend." She patted your head.
"Weren't you supposed to try a skin too?" you asked, your girlfriend still patting your head.
"Sure. Did you find any? If you didn't I have one I want to try."
