The black thong

You've always been curious about how thongs feel, might as well find out now. They untie you and hand you the thong to put on. As you slide it up your legs you feel the freshly shaven skin. You can't believe how... feminine your legs feel. If you didn't know that was your own you'd actually think you're feeling a woman.

The back of the thong pops in between your cheeks. It feels weird... not bad, but weird. Your sister puts a matching black bra on you. "Well, since the rest of us are in our underwear, I guess you can stay like that for now sissy."

Lilly pulls the back of the thong and lets it snap back into place while saying, "So what do we do now girls? We have the whole night!"
