Six months into the job, rookie office worker Momo still cannot learn her duties despite patient coaching from her boss, Abe. Labeled incompetent and isolated at work, she eventually collapses from anemia. Abe takes her home and cares for her, only to discover the huge breasts hidden beneath her plain clothes. His self-control loses to their temptation, and the two call off work to fuck from morning until night, refusing to stop until every trace of desire is spent. Plain glasses, black pigtails, and secret huge tits make an irresistible combination.
