My Friends Dick

My friend and I sometimes share girls or he shares them with me. When we first started doing this I realized that his penis was attractive and I was enjoying looking at it, watching her suck him. Once while waiting on a girl to arrive he put on some porn and pulled it out. I got hard immediately watching him as he teased his big dick. I really wanted to touch it and stroke it.
I’ve jerked off a couple of times now to that scene and I start imagining him telling me to suck him.
