Hmmm, let's see...
When I was "taking a piss" in the basketball locker room senior year, putting on my ghetto POS cable clamp/sock [words=http://www.mattersofsize.com/forum/showthread.php?44-Ace-Strapped-Jims-Joint]ace[/words]-bandage-around-the-upper-leg-to-hold-in-place [words=http://www.phallosan.com/shop/catalog/default.php?z=eNortjIxtVKyL0pNszWxMFcrSSxKTy2JL0hMT7U1UisoykyxtbBQSy4tLsnPjS8uKcrMS7dVsgZcMMpbEbo%2C]ADS[/words], my friend peaked over the bathroom stall, nosey mother fucker. He only saw me hunched over (just in case anyone like him were to peak in) and it looked like I was beating off. He told people that I was beating off and I just acknowledged that I was, and he quickly shut up after seeing it didn't phase me.
Another time, still before going off to college, I was hanging OTS with my vacuum hanger while listening to music on the computer at my grandpa's house. I didn't think he'd come home that early, I swore I had heard someone come in the house though. Once I didn't hear anything for a few seconds I assumed it was just a noise. Then he comes walking in and we both do a big OH WTF! How awkward can that get?
Last year I remember I left my pump out on my bed and my roommate was chillin in my room talking with me the whole time. Perhaps he didn't notice?
My roommate fresHydromaxan year would always say, "Oh yeah, pump up that sex toy," when I was pumping in the closet. He'd also make frequent comments such as, "You're one weird mother fucker." Haha.
