A naive new hire at a Japanese office finds herself the center of attention when her colleagues, a group of young, horny teens, convince her to join them in a secret after-hours tryst. The inexperienced girl is hesitant at first, but the sight of her co-workers stripping and fondling each other soon has her eager to join in. She tentatively touches her first cock, then eagerly sucks and fucks her way through the group, leaving her first day at work with a new definition of 'team building'.
