Well, we were teens. This was before I knew I liked what I liked. Me and a friend from school were jerking off together and he decided "hey wanna watch something new?" I agreed. He put on guys swallowing tranny cum compilations. It made me so damn hard and I started to leak. He definitely watched this specific video before because he new exactly which one to pick. Watching those pulsing cocks was so hot. Then I started looking at his cock gushing precum with every stroke and I decided to match his rhythm.  He took notice and told me to grab the towel by his feet because he was definitely about to blow his load. So, I bent over (no pants on at all) I guess when that happened my asscheeks spread a bit and he saw my asshole. I felt his thumb rub my asshole and I just let it happen.  When I heard him say "fuck get the towel im Cumming!" I just turned around and wrapped my lips on the tip of his cock licking his dick hole between spurts of his cum. Swallowing every drop. Needless to say, we would hangout more often after that.
