I am not a top, I consider myself mainly bottom. For a few years, I had a fuck buddy who was an amazing top. He was very talented with his tongue and his dick and he was all about working my dick and hole.
One day, he asked me if I would fuck him. I wasn't sure at first, but before I could answer, he started working his tongue into my hole and that always drove me crazy. When he asked me later, I told him that I would love to do that for him. So I started with my fingers working his hole. He was super tight. After I had loosened him up a bit, I asked if he was ready. I poured a lot of lube on his hole and on my dick. He grabbed the poppers bottle and I slowly worked my dick into his hole. He was super tight and I've only fucked one tighter hole and that one hurt and was not a good time. But this one felt amazing. After he got used to it, I went to town on his hole. He enjoyed it very much and thanked me for doing it for him. He never asked me again.
