Yuu Tachikawa found a pornographic website with an AV actress that looked like his mother and started jerking off to her image. While thinking about his mother he masturbated to climax, becoming more and more lost in fantasy. One day his real mother caught him stroking his erect penis. He knew it was wrong, he knew his lust was one-sided, but he couldn't control it any longer. He told her about his increasing fantasies, and as his anguished arousal curved into her hot ears, she reluctantly agreed. Yuu set up a camera and his mother gave an erotic interview while taking off her jeans and opening her legs. That's when he asked her to change her panties for a diaper. Perplexed and obedient, she did as he asked, and his excitement exploded. This was the lewdest, sexiest moment of his life... [From DLsite English]
