Shinji is badly injured after falling down the stairs at the cram school. Unfortunately, his parents went on a trip and he was the only one at home. Worried about Shinji, his older brother Kazuo and sister-in-law Tamaki came to take care of him. Shinji, who had been attracted to Tamaki for a long time, was glued to Tamaki's appearance even though he was physically disabled. But now I can't even masturbate... Then Tamaki, who notices Shinji's suspicious gaze, makes Shinji promise to "just watch..." and shows off obscene acts to amuse him...
