I hope my brother never reads this, but I've tried on a lot of his clothes. I would wear his shirts and he would say, 'that's mine,' and I would say that I didn't know, that I just found it in my room, etc... Eventually I cut the crap and just wore a couple of his shorts and things that fit me and would be like 'oops'. A couple time I would wear his boxers over my own underwear to try them on and see myself with that look that guys (and gals) get when you can see the elastic band riding above the top of the pants. x___x I just liked looking at myself like that. I also needed to figure out what my size would be so I could buy my own and was too scared to ask.
