I'm a bi versatile black man in my late 50s. 
I lived in Philadelphia for some years and had a great time in the bath house's and book stores there.  Here is one of my get hard memories.   One night I was very horny, lol I'm always horny.   In the bath house I used to visit weekly there is a dark room maze area on the second floor. While walking around up there, I passed a middle aged white man with a nice body, hairy chest and nice cock.  As I passed he touched my cock, while he stroked me I grabbed his ass.  We both got hard at the same time.  He was already lubed up and so was I.   He turned around and offered me his ass.  I needed a good piece...and he wanted my cock.  I began to slip into his ass and he was so warm and just tight enough, I began to fuck him slowly and stroke his cock at the same time. His moans really turned me on, but his hard cock turned me on more.  He was about 6 inches,  not too thick, a very good size.  I pulled out and turned around,  I bent over a little to get my hole to the right height.   I'm 6'3" with long legs.  He moaned again as his cock slipped inside of  me.  His hands were on my waist and he began to fuck me about the same pace as I had fucked him.  I knew then I was about to have a great night!  It's not a guarantee that I would find another versatile guy that enjoyed both giving and receiving cock.  We went back and forth for about ten minutes,  he kept telling me how hot this was and how good it felt.  I agreed, several times!  We had an audience,  a black guy was watching but had had all of his clothes on.   I didn't really like that, the fully clothed part I dont mind being watched but if I'm butt naked you should be too, lol.  I was getting fucked when the guy pulled out, slapped my ass and thanked me.   Neither of us had cum.
Almost immediately I felt a hand on my ass, I was still horny as fuck.  I then felt a hard cock pressed on my ass, and it was bigger and thicker than the one that was just inside of me.   I turn my head and saw the guy that had been watching.   He slowly slipped into my ass and began to fuck me slowly.   It felt so damn good!  I bent over so I could get all of his cock in.  After a while him had me stand up and he hugged me and whispered " I want to cum in you so bad" I moaned and told him I wanted it too.  He didn't pick up the pace, he just went in deeper after a few strokes he gave me a squeeze and kissed my neck.  He said to me you are so fucking sexy,  I said thanks as he pulled up his pants and left the booth.   I felt great as I walked to the stairs and his cum began to run down my leg.   I didn't touch it, just smiled as I thought about what I was going to do next.

nice story guy
