Would boyfriends/girlfriends dare to experience bare buttocks through plastic wrap? IENE-742

We invited some close male and female friends to the filming location and let them experience bare buttocks for the first time through plastic wrap. Although they were surprised when they heard about bare buttocks, they cooperated under the lure of the prize money. Practicing bare buttocks made their vaginas really want to be fucked!? In the end, they just slid in and ejaculated!
