The guy was enticed by his girlfriend's sister's body when he entered the room. He couldn't resist her and wanted her right away. Dropping down his pants and ready to go, he quickly slid his penis into her throat then proceeded to fuck her hard. The little sister moaned in pleasure as he thrust deep inside of her, until finally cumming inside her mouth. His girlfriend never woke up through it all, and the guy had fulfilled his naughty fantasy.
