Sumire's husband, after being laid off and caught cheating, was given an ultimatum by his wife: divorce or strict ejaculation control via a chastity belt. He chose the latter. Now, while she openly carries on affairs with younger men, she taunts him with revealing outfits, teases his body with orgasm denial, and forces him to listen to details of her infidelity, keeping his sexual frustration at its peak. The husband has become a cuckold masochist, aroused by the thought of other men possessing his wife's body while being unable to touch her himself. She strictly controls his ejaculation with the chastity belt, denies him permission to masturbate, and has declared that marital sex will never happen again, completely dominating him.
