This video is called "Nakadashi Naclures α"! It features sample footage of both male and female idol groups participating in secret parties where they can release their stress by having wild sex despite their strict rules against dating. The parties are held in a hidden room provided by the producer, who also happens to be an idol prodigy himself. He wanted to give them a place to let loose and have fun. The video includes lots of hot action like creampies, big tits, orgies, oil play, and more!
