A work provided by Kariotoko-san (46 years old). His wife is 35 years old, works as an accountant, and enjoys mountain climbing. His interest in NTR began when, during one of her work trips in stage lighting, she met a man through a dating app and had sex with him on their own bed. That day, Kariotoko-san returned home earlier than expected and caught them in the act. When confronted, she admitted it had started as a physical relationship with this man. Initially overwhelmed with anger, over time he began to feel jealousy and a sense of control, gradually developing an interest in NTR. He discussed it with his wife and persuaded her to continue the affair under his direct supervision. Rather than NTR, he shifted toward "netorase" (making her cheat), actively searching via social media for the right man. Emphasizing strict control, he required STD testing and eventually found an amateur-type man. Though appearing to be a player, this man consistently acknowledged the husband's presence during sex and showed genuine affection toward the wife. His actions reflected a complex mix of feelings—love for her and fascination with the NTR dynamic. The footage thoroughly documents the unfolding relationship between the wife and the outsider, featuring passionate scenes including kissing, nipple play, cunnilingus, blowjob, and intercourse. The wife's movements and expressions, along with the husband's dominant stance, highlight conflicting emotions throughout. The work captures the intertwined themes of love for his wife and growing arousal from NTR.
