I stumble upon my stepsister's solo sex session and join her in her room

As I was returning from the store, I decided to drop by my stepsister's room in the dorm, and as it turned out, she was doing some solo stuff at that time. I couldn't help but notice that she was pretty much into it and, as a true guy, I couldn't resist joining her. It's worth mentioning that my stepsister is a real hot chick with a nice body and a crazy pussy - she's a real sex-mad Latina. So, after a short talk, we both got down to business and as soon as she took off her panties, she started sucking my cock. It was a real pleasure for me to watch her doing that because she's a real amateur in everything related to blowjob and it was the first time I saw her doing it. But it was not enough for us and after a hot lesbian sex we both had to get our dicks sucked by this hot amateur teen who is definitely worth fucking.
