ADN-645: The story of a truck driver and a frustrated, adulterous big-breasted wife... The young man at her part-time job has the masculine appeal her husband lacks, making her soaking wet. Hikari Ri.

After marrying her office worker husband, Haruka's sex life becomes monotonous, leaving her sexually frustrated every day. One day, at the restaurant where she works part-time, she encounters truck driver Kenta, whose thick masculine aura—lacking in her husband—makes her body involuntarily moisten. Kenta's rugged charm and muscular physique completely conquer her, and the two soon fall into a passionate adulterous affair. In the truck cab, motels, and even her home, they indulge in fervent lovemaking, with Haruka experiencing unprecedented orgasmic pleasure. During her husband's business trip, Kenta sneaks into their house, and they engage in wild sex until Haruka is utterly immersed in this forbidden desire, unable to extricate herself.
