When I was a top, I had 2 times that I fucked a guy most of the night. Both times, we would stop and take breaks for drinks or washing up a bit. But both times we started around midnight and the sun was up when we ended. Neither time was non-stop though.
As a bottom, I had been chasing this guy for a few years. We were wanting to hookup but it never worked out. Then one night, a few years ago, him and I were both available to hookup. He came over, I liked and sucked every part of his body (he was hot! ) We made out for a while and then he started to fuck me. His dick is about 7.5" to 8" and a bit thicker than average with a big head. We fucked in every position imaginable and a few I had never thought of. After about 90 minutes, I was getting tired. We took a 10 minute break. I got a drink and he did some coke. Then he started fucking me again. This time it was a little bit longer than an hour. I finally had to tap out, but he promised he would cum in a little bit. I let him fuck me for another 10 to 15 minutes before he finally got off. It was an intense fuck and I enjoyed it very much.
