When my girlfriend Moe started living with me, we were wrapped in happiness—until one day, a sudden phone call shattered it all. The caller was Saejima, a creepy otaku, who seemed to have already laid his hands on her. While checking Moe's room, I discovered a gonzo video he had shot in his apartment. In it, his cock was visibly much larger than mine, and whenever he touched her, she let out completely different moans, climaxing repeatedly in a way I'd never seen before. Watching her pleasure being stolen by another man crushed my heart. The story unfolds with Moe torn between growing anxiety and inner conflict, as her emotions begin to shift toward this other man.
