He puts his sister's cock so hard that he almost cuts it in half

Not having a girlfriend is something that leads you to look for any alternative to get your cock hot. What this guy does is go to his sister's room and ask if he would leave her pussy to put his tail and let off steam. At first he says no, but when he sees the piece of cock that has the thing changes. The brother puts his cock so hard that since the girl is super thin, everything is marked on the body giving the feeling that he will end up splitting it in two. Because uncle doesn't cut himself and fucks her bestially.
