The guy managed to cheat on his girlfriend with her stepsister

The guy came to visit his girlfriend to chat a little and spend time together. And when she left, he himself did not understand how it happened that he cheated on her. It’s just that his girlfriend had a very lustful sister who quickly seduced him and dragged him into bed. The guy caressed her wet pussy, and she gave him a great blowjob. As soon as he penetrated her juicy hole with his big dick and she started moaning, he cheated on his blonde with pleasure.
