My nephew turned me on again

It was a few weeks now with my Nephew Ricky living with me and my wife. I haven’t really had the oppertunity to get him alone for quite some time and when I did I wasn’t sure how he was going to react.
Finally, I was going to pick up my cousins daughter at the school after her play. I asked Ricky if he wanted to come for the ride. Sure he said.
Well we drove to the school and sat in the car outside waiting. I struck up a conversation on what my feelings were sex wise and asked Ricky if it was possible to do again what we did the first night he moved in. His awnser was kind of mixed. He said I’m not sure what to feel at this time. It felt good and all that but I just don’t know.
I leaned over and stroked his leg and said that I am not looking for a lover, just sex to keep us feeling good once in a while. My hand slid up to his crotch and molded over his big penis very softly. I could feel him push toward my hand with his body and relax into a dreamy feeling of extacy. I probed deeper and harder with my strokes, his breathing was becoming heavier. I then reached over with my other hand and worked on getting his fly down with little resistance. I knew I had him turned on at that time and so was I. My cock was hard and stretched out to the max in my pants.
I undid the top of his pants and fumbled to get room to pull out that big cock of his. It was hard as a rock and huge in my hand. I bent over and took it into my mouth and licked the head and down his shaft.
