I had a fuck buddy that was a true 7" by very thick. Every Sunday morning while our wives were at church I would go visit and he would fuck the hell out of me. He always me me at the door naked, and he loved for me to blow him. He said I was the only guy who could get him off orally. He liked to fuck me on my back so he could watch his cock go in and out of my ass.
One time, the only time this has happened to me, I came with out touching my cock. When he shot his load, I could feel his cock swell and get harder. When he came I just gushed cum all over my stomach, neck, and face without touching myself. I would usually not cum, so I could continue to pleasure him all morning. He could cum several times in a couple of hours. I have difficulty sucking cock after I've cum, so I would hold out until right before I left, or even wait until I got home.
Right after we shot, he pulled his cock out, grabbed a hold of my cock, and stuck his fingers in my ass. I'm not real sensitive after I shoot, I can keep it hard for the next round. I have somewhat of a finger fetish, he had very large hands. He was a gardener, and he had large rough hands. I don't know if it was 2 or 3 fingers he stuck up in my hole, but he touched a button, I've never found since. I immediately and violently shot again all over my stomach. I'll never forget that sensation of riding his fingers and shooting so violently.
I've not seen him in years, but I have a pic of his cock I keep on my email. Every once in a while I open it up and dream about the sex we had.
