As a swimming instructor, I was secretly involved in an affair with my student, Toko, enjoying illicit sex with her in the showers after lessons while keeping our relationship hidden. One day, Toko brought her daughter, Ena, along. While teaching the cheerful and innocent girl, she suddenly approached me, curiously asking, "You and Mom are really close, aren't you?" Surprised by her words, I couldn't resist the warmth of her touch as she drew closer, and soon I found myself meeting her secretly by the poolside. From that day on, I began intimate relationships with both Toko and Ena. Ena easily opened up to me, while jealous Toko increased her post-lesson sex and hotel invitations, eventually leading her daughter to seduce me as well. I was living in absolute bliss—until one day, Toko summoned me to a hotel, and there I found Ena waiting too. It turned out they had already discovered my affairs with each of them. Panicking, I tried to apologize, but instead of getting angry, they happily proposed a reverse threesome. Falling into a mother-daughter reverse 3P, I became their shared flesh dildo, completely submissive to their pleasure, as they drained me of every last drop of sperm until they were fully satisfied.
