FC2-PPV-2751500, submitted by Kariotoko-san (46 years old). The woman is 35 years old, enjoys mountaineering, and works as an accountant. Her husband's interest in NTR began when he discovered his wife's (35 years old) own infidelity. Kariotoko, who runs a lighting business, often had to leave home for long hours due to stage and filming work. During one such absence, he learned his wife had been having sex with another man in their own bed—an experience that deeply shocked him. This personal trauma infuses his work with profound depth and raw, authentic emotion.
