Me and my girlfriend nana, a university student about to graduate. With a job offer from a top company and graduation trip plans, we're working hard at our convenience store jobs. Lately, I've been paired with the middle-aged manager for late-night shifts. I'm worried that my beloved nana might be harassed by the creepy manager... surely not... “It feels better than my boyfriend!” On my birthday, nana doesn't show up at our agreed time, so I call her and hear the voice of a woman who has been fucked senseless by a huge cock.
