USBA-032 Adultery Distance: A married woman, Riko Fujimori, who was raped by her coach during her student days and fell into masochism and nymphomania through pleasure-based training in humiliation and degradation.

Three years into our marriage, I was spending peaceful days with my kind husband. Then one day, I reunited with Coach Oshima, someone I had admired during my student days in the club. Perhaps it was pity for his lonely appearance now. Knowing it was wrong, I still ended up in a forbidden relationship with him, reaching climax countless times under his fingers and tongue. Before I knew it, obeying his commands became natural, and I became addicted to sex with him... as if I had been trained.
