One day, Nao, a MILF mother, returns home from shopping and is surprised to find her son lying on the sofa, his underwear removed—his body still immature. Concerned about his development, she gently peels off his undergarments. A soft, tender penis emerges, and its scent overwhelms her senses, shattering her rationality. She leans in, pressing warm, gentle kisses upon it. In that moment, the relationship between mother and son takes a new, forbidden turn.
