My step sister is 15years younger than me. we were not raised together. I was out on my own by the time she became my step sister. We messed around from time to time. She had a very hungry pussy. In other words she love to have it played with.
Later our playing around turned to sex. She is a natural squirter. Loads of it too. While licking pussy she would cum in my mouth so much that I couldn't swallow all of it at once and wold loose some. Sometimes I would not swollow right away and I would keep a mouth full to put on her breasts. Wow. such a turn on for me. she would cum again some time 3-4 times. I loved giving her oral sex as much as screwing her.
Some times her squirting would be partly pee. I found that I loved it when her pee was mixed with her cum. Once in awhile she would be so hot that she would pee in my mouth while I was licking her. I would swollow and loved every drop. It was when her pee was mixed with her cumming that realy got me where I would almost cum just from that. She never would let me pee on her though,
Thats ok, I enjoyed her pee and cum so much she didnt have to let me pee on her. She would give me extremely good head and swallow. She was not keen on that but when she did she always wanted to share my cum with me. It was kind of like if I wanted her to eat my cum then I must eat it too. Thats ok, I loved it. Many times she would ask me to clean the cum from her pussy after I finished, she found that I loved the taste and texture of my cum from her pussy mixed with her cum. Wow, I want to cum just thinking about it. Yummy
