[Aoyagi Kabota] After my boyfriend used his fetish to put us through "couple training," he easily scouted out my pussy's weak spots; now he’s thoroughly taught me pleasures I never knew, and I’ve developed a masochistic fetish even deeper than his. [MTL]

A nervous man proposes a couple‑training experiment to his confident lover, who eagerly agrees despite the explicit demands. As the session escalates, she is bound, gagged, and compelled to publicly declare her masochistic devotion while he watches, his small penis and sweating form underscoring the raw power dynamic. After the intense encounter, they finalize a contract promising chastity belts and further training, sealing a deeper fetish that has transformed both their bodies and desires.
