Nothing was going on that night for the guy and his gf. They were just about to go to sleep and the girl was in the shower when his brother stormed in. He said there's something he has to celebrate and sent the guy out to get some drinks. The sly brother then covered himself with the blanket and waited for the girlfriend to come from the shower. Of course it worked! She started sucking his raging cock, and those motherfuckers did not stop when she found out it wasn't exactly her boyfriend.
