I was helping a male friend move a few weeks ago and saw some pictures I maybe shouldn't have. The lid had come off the box they were in and it easily contained a 100 nude pictures of guys. My friend doesn't know I had seen the contents of this box. I wondered why he had them and being curious started looking at them. I began to recognize a lot of the guys in the photos and soon came across pictures of them masturbating and engaging in sex. I then saw some of my friend doing the same. They were sucking and fucking each other. I never knew my friend or the other guys I recognized were gay but apparently they are. I now am concerned that he might have some ideas about me. We have seen each other naked before and on a couple of occasions he even suggested we tan naked together which we actually did. I wonder if he may have some photos of me somewhere because some of the photos I saw seemed to be of guys just causally nude and a quick photo of them snapped possibly without their knowledge.
