[Reducing Mosaic]SSIS-021 I was forced to share a room with my despised sexual harasser boss at an onsen inn. From check-in until checkout, I was relentlessly raped by that incredibly virile middle-aged man for 12 hours... Shio Mi Mai

A new employee named Shio-mi at a construction company's sales department has always hated Sakawa for his severe sexual harassment. One day, it was decided that she would go on a business trip with Sakawa. After finishing work, the two headed to their accommodation, but for some reason, only one room had been booked… Shio-mi wished time would pass quickly… Meanwhile, Sakawa mixed sleeping pills into her beer… Sex marathon in a confined space with a lecherous boss until morning! A drama where she is made to climax multiple times despite hating it from the bottom of her heart.
