Blackmails her sister to fuck her after discovering she is a webcammer

Finding out that his sister is a webcammer opens up a world of possibilities for this guy, who knows that he has free pussy for the rest of his life. The guy goes to his sister and blackmails her by telling her that either she becomes his whore or he tells her parents what is going on and fucks her alive. He eats her pussy first, because he wanted to taste it, and then he already sticks his cock in her mouth so that she starts sucking it like a good slut before he fucks her hard on all fours. He blows her super hard without caring at all that she is his sister.
