An office lady is given an aphrodisiac in her office. As she continues to work, unaware of this, something strange happens to her body! She masturbates with her fingers while worrying about the people around her! However, that is not enough... "Desk corners," "lockers," "cleaning tools," etc. She cums with her legs trembling! And then she cums again and again until she loses her mind, and then she fucks him hard!
