Step brother tied virgin stepsister for watching porn to solve her problem

My stepsister was doing homework, but since there was nobody at home, she decided to watch a little porn. Unfortunately for her stepbrother came home and became angry. He took her by the throat and threw her on the sofa: "If you want a dick, then suck mine." After that, he put her doggystyle and began to fuck. Reason returned and his stepsister began to push him away. He went behind the rope and tied it, and in order not to scream, he inserted a gag. After that, he began to have fun with her pussy and fuck as he wishes. In the end I finished gagging, having told me to repeat and not to tell stepmom anything.
