He's not really into it, but she keeps going until he gives in and lets her suck his cock. Then they move on to the bedroom where she's getting on her knees in front of him again, this time to get fucked by him. The guy is not really into it, but she keeps going until he finally gives in and fucks her. They continue to have sex in different positions until they both cum.
