Drinking at a classmate's house with a high school group. When a drunk boy starts talking dirty, the girls, though shy, begin touching each other's large breasts and getting excited by breaking taboos! Then, as they get drowsy from drinking, a mischievous boy starts pranks like pulling down their underwear! The girls wake up, but are forced to drink more and end up in a messy state! Exposed breasts! Fellatio! Vaginal beer and doing whatever they want! In the end, they even have unprotected sex in a lewd video!
