My ex and I liked to get together for a few weeks after we broke up...
"Susan" and I had been together on and off for about 10 years, and our sex was really great. After we finally broke up for good we still met up once or twice a week, and fooled around. I am uncut and 8 inches, and could give her multiple orgasms every time, and she loved it! But eventually she got sick of having sex because she worried we would end up getting back together, just as we had so many times before.
But she had a hot little petite Asian body and I was still super turned on by her. Once, I went to her place and she was on her bed reading. She was pretty much ignoring me, but was wearing a skimpy halter top and soft boy shorts-type undies and I was totally turned on by her body. I lifted her top to expose her belly and started to caress her soft skin. She wiggled and softly moaned to let me know she liked it, even as she kept reading. But she would not let me play with her pussy, so I knew sex was not gonna happen.
By this time I was completely hard and aroused, so I began slowly playing with my dick and shaved balls, getting more and more turned on. Despite the hundreds of times we had fucked I had not really jerked off in front of her before, but I started doing so this time. She mostly concentrated on her book, even as I getting closer and closer to blowing my load.
When I finally did cum it went all over her belly and her little titties, which I had been touching while I played with my cock. She commented that I blew a very big load, and that she thought what had happened was "kinky." We had a few more encounters like this, which I enjoyed very much, but eventually she got serious with a new dude, and my fun was over.
