Joy laughed nervously a bit, "Well that's a funny story. Well, you see, we can... control... those parts. So, I guess you could say we can... sort of 'open' them..." She poked her index fingers together, her over-manicured fingernails clicking together, "And your bra, too, just pull them back."
Alison, having received an order to just pull them back, did just that, and suddenly her naked breasts were exposed, her pink nipples hardening quickly in the relatively cold air as her blouse and bra had simply split open down the front and folded away. A draft told her that she'd done the same to her panties...
Joy gave her friend an apologetic look, "Sorry, I meant to say that you just had to pull them back if you wanted to do it, I didn't mean to tell you to do it right now."
Alison smiled, "It's okay." She then closed her garment-ized body, "That's still kind of funny, though, if you think about it. If you just stretch too much in gym, suddenly you're giving the whole room a free show."
Joy laughed a nervous laughter as she realized that this was a real possibility.
