Yuusuke, consumed by his intense lust, spent his days masturbating like a monkey. All he wanted was to have sex, with anyone, anyone at all. Unable to control his desires that had swelled to the point of clouding his reason, he caught sight of his mother, Shiho, cleaning while her large breasts swayed gently. Looking closer, he realized his mother had a damn sexy body... To Yuusuke, Shiho's physique seemed like a manifestation of a man's fantasies, straight out of a porn comic. Yuusuke's desires spiraled out of control in a dangerous direction.
