I had sex with my brother a couple of times once..The first time there was no penetration, just fucked between his ass cheeks and busted my nut all over his back, the 2nd time he finally let me put it inside, that first penetration into his tight ass felt amazing. He began to ride on top of me for a while then we switched to missionary. Man his moaning was sexy..then as we locked eyes I whispered in his ear "I'm cumming" he spred wider so I could get in nice & deep then I blew my load right inside of him. Best load I let off.
One other quick experience I had was with a random guy, nothing too hot there just sucked a load out of him is all.
