One horny night, he calls an escort to his home and is shocked when Mei Itsukaichi, the painfully serious accounting clerk from his company, arrives. She normally rejects every suspicious receipt, yet she has been hiding an astonishing hourglass figure and huge breasts beneath her office uniform. He uses her secret to reverse their workplace hierarchy and repeatedly creampies her. Apparently sexually frustrated, she quickly surrenders to cock and becomes his convenient sexual outlet, servicing him casually both at the office and at home.
