Today the company welcomes a new employee, Kuroi who is in charge of training her. From the first time they met, Kuroi was impressed by Riho's beauty. To welcome the cute employee, the manager decided to invite everyone to have a drink after work. Because they went all the way to the second floor, Kuroi missed the last train. Not knowing what to do, Riho asked him to stay overnight at her house, and take the first train home tomorrow. When Riho returns, he changes into a thin, wide suit that keeps his nipples hidden in front of Kuroi's eyes! Riho also found out, but she deliberately got closer to him, took the initiative to let him squeeze his breasts, and invited him to fuck her! Although he has a girlfriend, Kuroi can't resist Riho's beauty. The guilt made Kuroi's cock even harder. And especially, Riho also lets Kuroi cum in her pussy over and over again, which his girlfriend has never allowed!
