My Boss Is a Hidden "Virgin" Pervert

Nanami works at an apparel company, but he has a secret he can't tell anyone: he's gay and a virgin. Not only that, he enjoys "playing" with one of the mannequins at the office late at night! One night his good-looking subordinate Fujieda sees him with the mannequin! Instead of exposing him, Fujieda makes him do a "masturbation show" with the mannequin every night after that. When they find out Nanami is supposed to be transferred, will their relationship change...?
