I was in the locker room in the military and just finished my shower. We were a couple of guys in the shower room all chatting along. I was talking to this one slender guy who was also naked and I had my towel in front of me while drying my chest. The towel was covering my dick. I was thinking I wonder if this dude is going to look at my dick if I lift the towel to expose it - so I lifted it slowly. Sure as nuts the guy's eyes locked onto my dick.
Kind of gave me a good feeling that the guy was having a peek and I noticed him doing it.
Any similar stories where you knew someone was watching you?
