My dream/wish is to do it with my son.

He is 12 nearly 13 slim, athletic and very good looking (he gets that from his mum). He often walks around the house fully nude, and I sometimes go to my room and wank thinking of him. I dream of pulling and sucking his cock, then licking his hole before slowly fucking him. I would fuck him slowly and deeply till I cum up his bum.

I've never done anything sexual to him, but I did have reason to spank him the othe day. He got an erection when I did and I was very tempted to wank him of. I managed to keep my self control and not do it though.
