"After all, even my husband betrays me. I guess somewhere in my heart, I can't trust men...," says Sawa-san, 34, who, upon discovering her husband's infidelity, herself took to the path of unfaithfulness and became addicted to extramarital sex. She is a full-time housewife in her seventh year of marriage with a 5-year-old daughter. "But, at least a firm, erotic penis never betrays me (laugh)," she says, expressing her desire to thoroughly enjoy a carefree, pleasurable sex without any lingering issues today.
