One day I was sleeping on a public dorm (in vacation, Guimarães, Portugal) and I started hearing noises of someone jerking off. I look down and discover the guy from the bunker next to me (I was above him) jerking off with the sheets covering his dick. Really slowly and enjoying, without worries about someone catching him at all. I started getting hard and getting close to see and listen better. Then, I decide to start jerking too, knowing that he is watching me and vice-versa. He then gets up to the top bed and continues jerking next to me. Next thing I know he gets to my bed and starts jerking my cock. I then told him to go to the bathroom and the night ended with him jerking me off until I came. (He was curious and had a girlfriend).
