MDB-713 — I Joined a Harem Gym Where Horny Trainers Commit to My Instincts! Yui Hatano, Hibiki Otsuki, Anzu Hoshi, Shuri Atomi

An out-of-shape man joins Zenzap after seeing an ad for the gym, whose motto is “Commit to Your Instincts.” He signs up to transform his body, only to find the place packed with gorgeous female trainers. They give his instincts a very different kind of workout, surrounding him for a harem session that drains every last drop of his cum.
