Elite office worker Ayase Maina is pushed to orgasm after getting extremely drunk and taking an aphrodisiac. She is highly sensitive, squirts repeatedly and gets fucked over and over on the sofa and floor. The accomplished, beautiful senior employee is celebrating the success of a product-development project she led. Though she normally avoids after-work drinking, she stays through the second party. Late that night, the group puts the unsteady Ayase into a taxi and takes her to a hotel—but another man is already waiting there.
