Second year at a major construction company. Usually, she's the unassuming Yuka, 24, of the administrative department. She has a secret side that no one must know about: during lunch breaks, she sneaks out of the office and indulges in extreme sex with a colleague at a love hotel. Alone together, Yuka squirms with desire. 'I can't live without this,' she says vulgarly as she swallows a pill with her wide-open mouth. Her body becomes sensitive and hot; every touch feels like it's on her genitals. Deep, sloppy tongue kissing. Her crotch is already soaked. They have sex right at the entrance. Their lust still unabated, they go for round two in bed. Even on dangerous days, she lets him release inside her abundantly. She's my personal flesh toilet.
