My beloved beautiful fiancee was turned into a sex slave at a hot spring inn

Ishigami, who works for a major advertising agency, dates Ruisa, who works as a receptionist at the same company. However, Ishigami, who is terrified by Ruisa, is always angry at Ruisa, who is engaged but never lets her do it raw. One day, a boss at work and a senior invites Ruisa to check out the comfort trip... Set in a hot spring inn, the perverted NTR fetish awakens and the repeated intense gang rape in a muddy bathtub dirty with semen crossover. #YoroP
