Kotaro, who has weak nipples, works hard at muscle training to correct his weak points, but even though his body has become stronger, his important nipples are still sensitive. One day, her mother's friend, Nozomi, came to her house. Nozomi, who was sexless with her husband, changed suddenly when she learned about Kotaro's erogenous zone, stealing her surrounding eyes and playing with his sensitive nipples. Kotaro, who reacts to the pleasure of being sucked and licked over and over again, is confused by his first experience, but gets absorbed in her nipple torture.
