Before that day, the dude thought that one should have no principles to sell his girlfriend but that day he faced that situation. OK, he managed to cope with his jealousy and to sell his girlfriend but he did not think the fucker would bang his beloved chick in different positions and would comment the process. Yes, the dude got out of a difficult situation but from now on he will think about dirtiness of his girlie and will fantasize about a stranger fucking her wet slit.
