Shiori-chan is a perfect beauty who is usually bright, ranks at the top of her class, and is admired by everyone. But her hidden side, which no one knows, is a sadistic nature that switches on the moment she finds a masochistic man—she's a perverted beauty who loves making men drink her pee...! One day, Shiori-chan locks onto a transfer student, drags him into the restroom, and suddenly makes him act as a toilet, pouring her urine directly into his mouth! A true sadist who tells him, "Don't spill a drop," and makes him lick up every overflow with cleaning cunnilingus! A classmate who splashes her pee anytime, anywhere! #CockP
