My stepbrother comes over and we have sex

A couple of days ago my stepbrother came over to our house, and as soon as he saw my mom he wanted to have sex with her. I was not against it because I had always thought that my mom is fucking hot. So, after a long talk with my stepbrother, we decided to have sex with her. Mom was very surprised when he began fucking her, but she did not mind it. My stepbrother fucked her very hard and I could see that he really liked it. Mom has a big ass and natural tits, and she is a real hot mom. She is also a very good wife and mother, but sometimes she needs a good fuck. She is an amateur in sex, but she is very good at it. She is a Latina and a Venezolana. She is not my sister, but I think that she is fucking hot.
