Koji, who was visiting his childhood friend's house, witnesses his friend's mother, Reika, indulge in masturbation. Koji, who had admired Reika since he was a child, stole the scene in order to make him a masturbation material... As I enjoy watching the images many times, I start to feel evil emotions. "If I show you this image and corner her, Reika might let me have sex with you..."
