Testing his younger sister’s anal stamina
He opens the bathroom door and finds what he expected to find. Right there he can see her completely naked and after examining her buttocks, he realizes that she is willing to do some of the pranks they always do when they are alone. Right now his little sister is already horny and he is ready to test the young girl’s anal resistance. For that, I had to put my cock inside her ass so many times that normally any whore would feel pain. Only that she is already used to having it from behind, no matter that it is a very big cock.
