BASJ-019 - A cruel, lewd, and deranged married woman, Obayashi Reiko, who distorts a boy's sexual preferences and makes his life a hard mode.

A boy entering puberty with unending interest in sex. He desperately wants to do erotic things and falls into the trap of a married woman. She enjoys distorting younger boys to her preferred sexual kinks, becoming excited as she is begged by those she has carefully raised as M to ejaculate. He doesn't realize his life has become hard mode, simply clinging to the married woman because he wants to ejaculate. Eventually, he is teased and made to ejaculate, and this is repeated until he becomes unable to ejaculate on his own. Once he becomes the ultimate complete M slave, an endless cycle of ejaculation continues until the woman is satisfied.
