Camp Buddy Encounter Fun

last fall I went hunting with a buddy and we were sitting around campfire having a few beers and talking when he started telling me how his wife would not have sex with him anymore and how horny he got so often he could not sleep. I thought I was only one like that. The more he talked about how he would watch different kinds of porn and jo to get relief the hornier i got. After a half dozen beer i went in camper and climbed in bed when Bill cam in he did not sleep on couch instead he climbed in bed with me, I was awake but pretended to be asleep i could feel him toss and turn and soon felt him against my ass with his hard cock pressing on my ass crack i ignored it but it was getting wet and i felt him pull my shorts down and the wet head of his cock pushing into me, it scared me but aroused me at same time. He reached around and started stroking my cock which was semi hard i was getting turned on and i felt the head of his cock pushing on my ass when he suddenly came all over my ass . Made a big mess he said oh dam i am sorry got some paper towels and started wiping me down as he did that i just got harder and he said here let me help you with that as he took me in his mouth i came rather quickly. I have been feeling very guilty about the ordeal but at the same tim i get horny when i think about it we never did it again or talkede about it i am not sure I want to but not sure i dont either lol.
