My son's former homeroom teacher, Natsuki, who kindly advised him about his future back in school, is now a soapland worker I encounter again. She asks me to keep this a secret from my son, yet we plunge into a forbidden affair filled with guilt and desire. Our secret encounters don't stay confined to the brothel—we begin meeting at her house when her husband is away, indulging in intense, passionate sex. Though she tries to create distance, unable to resist her overwhelming lust despite being married, she soon invites me back. In hidden moments, creampie after creampie deepens our illicit bond.
