Oh man that's hot. The first time I ever did it, I was in a 69 with the other guy on top getting fucked from behind. I had a birds eye view of that hard cock plowing that tight hole. And when he bred that hole, his cum splashed out and I got a good taste as it ran down my buddies ball sack.
All these comments about spit-roasting reminded me of a time I was in the locker room of the bathhouse in Honolulu. There was a guy in there with an 8" dick which wasn't too thick wandering around, hard as a rock. I was in rut to get fucked and he was an obvious challenge; I'm good with length, and the width would not be a problem. So right in the entry, in front of a row of lockers I sidled up to him. When he showed interest, I bent over, hands on thighs, and backed onto him. He slid in pretty easily and muttered something about how glad he was that I could take him all. As we settled into an amazing connection we drew a small crowd. Guys love to watch a long dick pumping a happy ass, and some guys started jacking. One guy moved in front of me, I opened wide and he fucked my face in rhythm with the guy fucking me. Whew. So hot, so much gizz from the three of us and the watchers.
