I was on vacation in South Beach, Miami with a friend of mine. I had just separated from my wife and was blowing off some steam. My friend, Mike, and I were living it up, drinking, partying, and hooking up with women. One night we were at one of the beachfront clubs. I had been drinking all night and felt a little woozy. Mike and I got separated, he hooked up with some girl, and I felt like I just needed a walk to clear my head. I walked down the beach a little and sat on a bench not far from the shore.

My head was still spinning but feeling better than earlier. I was smoking a cigarette when I saw a guy headed my way. He came right up to me and started a conversation. He asked for a cigarette, introduced himself--Mark was his name. He sat down and started talking like we were old friends. Mark and I just talked about everything, I felt right at ease and I honestly had no clue where this was headed. Mark suggested that we take a swim and I thought it would be fine, so we started to undress and I noticed him looking at me, I guess because I was looking at him. I couldn't take my eyes off of him. He was black 6'3" about 210lbs, in great shape, with a nice chest and great abs, strong arms and shoulders, thick thighs, and a big dick with a fat head and low hanging nuts. I felt a little self-conscious because I stand 6'1" about 200lbs with a nice natural build; my dick seemed very small compared to his. We got into the water and waded around for a bit, making idle chatter. Suddenly Mark swam up behind me and slowly put his arms around me and started to rub his cock against me. I was a little nervous because I could feel it sliding into my crack but the feeling of his hands rubbing my body made me feel oddly at ease.

Up to this point, sex with a man was something I had fantasized about, never thinking it would or could happen because I was married, and I never thought I would find myself in this position. Anyway, I reached back and for the first time in my life I was touching a cock other than my own and it was a big thick, black cock attached to a great looking guy who was in great shape. It started to rain and thunder so Mark suggested we get out and go to his place. I found myself just going with the flow, feeling like this is something new, something I had been thinking about for a while never thinking it would happen and here it was. We got dressed, gathered our stuff and crossed the street to his building.

There wasn't much conversation on the way up to his apartment; I was starting to feel a little hesitant. We walked into his apartment and he said he was going to shower and that I could shower also. I waited for him to finish, he came out with a towel wrapped around his waist and I couldn't stop looking at his body and the outline of his cock through the towel but I couldn't stop feeling embarrassed about it. I took a shower and when I came out Mark was lying on the bed naked. I had a towel wrapped around my waist and I sat on the edge of the bed.
