i was in a bathroom of a mall, when i realized that the walls facing the urinals were completely reflective, so i could see everyone else peeing. there was this old dude two urinals away from me who kept looking over at me, and for some reason though at first i was creeped out, i got turned on and started jerking myself off. he couldn't take his eyes off my hard dick and i stroked it a lot and was close to cumming when someone else came into the bathroom and so i jolted out.
but now thinking about it - fuck, what if he was filming me somehow? i just googled this and such "spy" stuff is everywhere... gahhhh
