I'm not proud of it, but yeah I had a friend in Jr. High and freshman year of high school that I would hang out with a lot, and sleep over at his place. His older sister was away at college and occasionally I would sneak a chance to try on her clothes. I even managed to talk him into doing it too like it was just a mischievous game to play. I think all men are at least a little bit curious about women's things so that's probably why he was willing to indulge it, but as far as I know he hasn't continued to crossdress since then. I do feel guilty about invading her privacy like that, wearing someone else's panties is definitely a no-no. I started buying my own as soon as I had my own car to drive to VS.
