The second installment of our popular project! We asked a friendly college couple to abstain from sex for a month and have sex in a special studio! We then added a big-dick AV actor to the mix! When we asked them to try threesomes for the first time in their lives, which would the female college student choose: "the love of her boyfriend" or "the pleasure of a big dick"?! At first, the college students are confused about threesomes, but gradually the AV actor starts to blame them and they end up embarrassed in front of their boyfriends! When a big dick bigger than her boyfriend's is inserted, the pleasure runs through her body! When she is pistoned hard, she can't stop climaxing!
