Broke guy lets evil friend have sex with his GF for money

In a desperate need of cash, a guy comes to his friend's place, who is known for being quite evil. He offers him a deal - to have sex with his girlfriend in exchange for some money. The guy agrees, even though he feels quite bad about it. His girlfriend seems to be okay with it as well, and soon enough, they both start getting down and dirty. The friend takes off his shirt, revealing his muscular body, while the girl takes off her top as well. She starts giving him a blowjob, while the guy watches in the corner. Soon enough, she takes off her panties and rides him, while the guy continues to watch. The friend gets up and they both take turns fucking her, until they both cum inside her. The guy then joins in and they all have a wild threesome. In the end, the guy feels even more depressed, and the friend just laughs at him.
