Shiori Yomoto is a serious and honest new office lady. She is ordered to go on a business trip alone with her boss, who she finds physically repulsive... She gets drunk and ends up in a hotel room... "Please stop, I have a boyfriend..." She resists in vain, but she feels the cock being thrust into her and drowns in unprecedented pleasure... The timid new employee awakens to her masochism. Her creepy old boss' time-honored techniques are a perfect hit, and even though Kokoro is reluctant, her pussy is soaking wet as she is made to cum over and over for 72 hours!
