A big-breasted L-cup married woman who moved to Tokyo from Niigata is filled with pent-up frustration. She secretly uses a dating app behind her husband's back to meet strange men in Tokyo for secret rendezvous. She hasn't been intimate with her husband in a long time, but deep down she's quite a pervert. Her body, made sensitive by daily masturbation, constantly craves sex, and once is never enough to satisfy her. She continues to meet other men, and her desires only accelerate. A raw, desire-driven cuckold sex unfolds, steeped in a sense of guilt she can never confess to her husband.
