Momo is a new office lady who hasn't learned her job even after six months. Her boss Abe is patiently teaching her but she's not showing any signs of improvement. She's labeled as incompetent by those around her and has no place in the company... a real useless employee. Meanwhile, Momo collapses from anemia. Her boss Abe takes her to her room and looks after her, but he notices her hidden big breasts. He tries to keep his cool, but his dick is completely defeated by the temptation of her big breasts. The two take a day off work and keep doing it from morning to night until their sexual desires run dry. The combination of plain glasses, big breasts, and black hair in a ponytail is just too destructive.
