One afternoon I went over and helped a friend move in some new furniture. It was just the two of us and we were very tired after the task. We decided to sit out by his pool and relax. He offered me a beer and brought me a wet rag to wipe my face. I have been friends with him for a few years and never minded that he was gay, and he never made me feel uncomfortable.

It was very hot outside and I suggested we jump in the pool. He agreed and he went to get us some swim trunks.
I went inside , changed and realized that he was a smaller guy than me and his trunks fit really tight.
I went outside while he was still in and went ahead and jump into the pool. He came out shortly with shorter trunks. He teased around and bent over in front of me.
That's when I couldn't help but notice that he had a good looking ass. He got in the pool, and we just continued to talk and drink. He started to complement me on my shoulders and asked if he could massage them. I said sure not really thinking beforehand. As he was massaging me I started to lean back against him and that's when I felt his erection.
He apologized to me and was embarrassed. I felt bad and said not to worry about it. I could tell he was embarrassed so I , hey you want a massage? He smiled and I started rubbing his shoulders and neck.
He was between me and the edge of the pool. I was rubbing his shoulders that turned into rubbing the chest. I suddenly felt his leg wrap around mine.
Neither of us talked and that's when I started feeling myself get a Erection. Before I could fight it off it was to late. It was pressing right up against his ass. He started grinding up and down on it. I ran my hands down his chest and he was rock hard.
I reached into his shorts and pulled his dick out and started rubbing it. At the same time my other hand was grabbing his ass. I was so hard, I couldn't control myself. He whispered to me to fuck him.
I pulled down my shorts, then pulled his down. He grabbed my cock and helped me stick it in him. He was so tight. He started breathing hard, and once I was all the way in I leaned forward and kissed him on the cheek.
I started thrusting faster and faster. I then reached around and started stroking him fast. Seconds later he yelled out "I'm gonna cum!" And a jet over semen shot in front of us. I wasn't far behind. I had a death grip on his thighs. I moaned out oh fuck I'm getting close.
He told me he wanted all my cum in his ass. He kept saying fuck me baby. I couldn't last any longer and exploded inside him. As I was cumming I was squeezing his balls.
