After we had wanked each other's cocks, and then rested, Billy looked up at me moving his body and face towards my face and gently kissed me on the mouth. His tongue still tasting of our cum, pushed into my mouth back and forth. He was fucking my mouth with his tongue. My thoughts about what happens next flew out the window as I took hold of his cock which was still hard and thick.
I broke from the kiss and looked down at his cock. It was so fucking hot - must be at least 8-9", with a juicy looking red bell-end exposed by me pulling his foreskin down. His shaft was thick but not too thick that I couldn't get my fingers around it. A deep blue vein was pulsing along the length of his shaft. I didn't have much experience of cock size, but I knew this was a big cock. His pubes were trimmed and his balls were big low hangers. I ran my hand over his balls and cupped them, then rolled them around in my hand.
I pulled his body on top of me so our cocks were rubbing together. I was hard again which doesn't usually happen to me so soon after cumming at my age. Billy's body, and cock were really getting my juices flowing. His hands on my shoulders as he was on top of me, I was free to run my hands all down his back till I could feel his firm little ass cheeks. We kissed passionately while Billy humped his cock against mine.
"Dad I want to suck your cock" he said.
