Designer Minako provokes new employee Matsuda with her big breasts and mini thighs. To relieve the stress of staying up all night, she begs the president to make her squirt with a rotor and a vibrator. She then masturbates in the locker room, making Matsuda watch, and gets him in the mood for some intense sex in the office. The three get drunk at a bar that the president treats, and engage in a wild threesome.
