A middle-aged man and a girl in a uniform entangle their tongues, dripping with saliva. Unable to resist, she is licked all over her erogenous zones, sweat, saliva, drool, and love juices, training her for a sticky pleasure. The two then drink her saliva and have a tongue-kissing sex session, becoming sticky and melting into each other. "I don't want to, but... I love this feeling." At first, she hated the clingy old man, but now she desires his vulgar lips, and her excitement never stops, her crotch gets wet, and she transforms into a perverted girl, waiting in agony for him to call her after school.
