Mariko Hino had long been aware of her husband's habit of staying out late and his infidelity, but she suffered in silence, unable to confront him. To her, he had once been the ideal man, but the harsh reality behind his facade weighed heavily on her heart. Her stepson, too, had noticed his father's behavior but chose not to speak of it, quietly supporting Mariko through the pain. One day, a major incident changes everything between them, and the stepson begins to see his stepmother not just as a maternal figure, but as a woman—sparking an intense, forbidden relationship filled with passion, guilt, and desire. This taboo story of a Milf stepmother and her stepson unfolds in the Alex series "The Taste of Mommy" from NEXT GROUP, exploring deep emotional bonds and carnal intimacy, including cowgirl-position scenes that mark their descent into incestuous love.
