I find this a little funny because if you masturbate enough, I feel everyone will be caught eventually. That is certainly the case for me. I masturbate pretty much every day, sometimes multiple times in a day. I do not cum every time, only cum 2 - 3 times a week (unless I'm really horny and may cum multiple times in a day, but that's a different story). Anyway, yes, I have been walked in on while masturbating, by family, wife, and strangers. Latest event was in a hotel room. I was masturbating while looking at some sex forum site and had the door locked when the housecleaning lady came and knocked on the door. I did not answer because as I said, the door was locked. However, their key can still enter, and enter she did seeing me nude and masturbating. I looked up and said I did not need anything and she said ok. My cock never missed a beat or maybe I should say my hand never missed a beat. She backed out and I kept masturbating.
