Since childhood, Mitsuru has been spoiled by his mother, Shoko. Mitsuru's affection for Mitsuru gets distorted as he gets older, and Shoko reluctantly accepts it. One day, a memorial service was held at the sister-in-law's couple's house, leaving her husband busy with work at home and Shoko and Mitsuru visiting relatives' homes. That night, Mitsuru, who is happy to be alone with his mother, becomes dependent on Shoko, regardless of the fact that he is at a relative's house. Knowing that Shoko is wrong, she steals the eyes of her relatives and puts Mitsuru's hardened cock in her mouth.
