In theory, this guy shouldn't have bothered anyone while he was having sex with his girlfriend, but suddenly he hears a noise: his sister approaches the room. The bride hides naked in a closet and her sister discovers him with the stick outside. But instead of being scandalized, he pushes him to the bed and starts giving her a blowjob. A noise from the closet makes him discover the bride and then between the two of them, they fuck him making a threesome where he starts to fuck the two pussies, digging his cock deep inside them.
