"Let's see. Um. I think I will wear this 13 year old girl," your girlfriend laughed. She held up the empty skin in front of her body. It was of a short brunette with rosy cheeks. Kind of cute.
"Why do you want to be her?" you asked.
"Well she looks absolutely adorable. I wouldn't mind slipping into her. Also, she seems skinny. Like, you know I've complained about the weight I've gained."
"Don't say that babe," you protested "You know I find you as beautiful as ever."
"Thanks, but it'd be nice to be skinny like her. Or, I think she's skinny. It's hard to tell when she's all deflated."
"Try her on then," you said.
Your girlfriend started slipping on the skin. At first it looked a bit comical, her placing her thick legs into what looked like the way too small legs of the skin, but it fit perfectly. It didn't even stretch at all. Now your girlfriend looked kind of silly with a pair of short skinny legs sticking out down from her larger torso, but only for a moment as she pulled the skin up, enveloping her torso. She pushed her arms through the skin's arms, and the skins arms came to life.
Only the last final touch was left. She pulled her head over hers. For a second you looked at the lifeless face of the skin, but then it came to life, her eyes opening revealing blue eyes unlike your girlfriend brown ones. She also did a cheeky smile.
In front of you was standing a petite 13 year old girl, a naked one. She was skinny, not with much of womanly curves, small pert breasts, narrow hips, a far cry from your giflfriend's usual thick figure.
Your girlfriend moved her hands acrosd her new body and at the end touched her nipple and smiled. "This body niiice," she finally spoke, her new voice a bit shrill.
"It's something," you said, feeling a bit awkward. Even if this was your girlfriend, she did have a young body right now.
She looked at you, up and down, having to crane her neck to look up at your face. She licked her lips. "I want to fuck."
"Like that? But you're 13?" you protested.
"So? I am not actually 13."
"Even then. It still feels weird. A little too weird I think."
She looked at you for a few moment. "I guess. If you're not into it, then I won't force you. Not that I could do anything like that as tiny as I am now." She threw a few mock punches at you, her small fists not being the opposite of threathening. "Still, becoming this girl made me really horny. I guess teenage hormones and stuff, so I still wanna fuck. Since you're such a lame pants I guess I could get into a different skin, or maybe you would be okay with cute little me if you wore a skin too? That would maybe make it a little less 'weird'. How about that?"
You pondered her suggestion
