Rieko, a middle-aged mother, lived her daily life unaware and unguarded, which drove her son to the brink of desire. One day, unable to contain himself any longer, the son forcibly pinned her down. Though initially resisting, Rieko was ultimately violated—and from that moment on, she began believing, "It's my fault for being so lustful," and started obeying her son's commands. She was made to perform daily blowjob services, and gradually, Rieko herself began awakening to pleasure. Unable to suppress the heat building within her body, the mother eventually started craving her son's cock, deepening their forbidden relationship further.
