I was at Steamworks in Chicago during pride several years back and the first guy I hooked up with there was about my age. We went to his room and were really getting into it, making out hard and sucking each other a lot. He was fingering me and pushing lube into me, i was hitting the poppers while he put a condom on and I started to ride him. He got it inside me and we started fucking, but he couldn't keep it hard. I could tell he was really trying to get hard again.
I pulled off him and stroked his cock, then slid the rubber off. He got hard instantly. I looked at him and moaned "fuck yeah." He nodded and I slid down on him, taking him balls deep bareback!
He wound up pounding me fucking hard. Riding him, doggy, on my back, then me riding him again. He moaned that he was getting close and I just kept on riding. He warned me again that he was going to cum and couldn't hold it any longer. I sank down on him as he shot his load deep into my ass. I wound up staying several hours longer and took four more loads that night.
