In the heart of Seoul, a traditional Korean massage parlour hides a secret. A young, inexperienced masseuse, Yumi, begins her work on a muscular, tattooed man. As her hands glide over his body, she feels a growing heat between her legs. The man, aroused by her touch, can't hide his growing erection. Yumi hesitates, then gives in to her desires, stroking him gently. He turns around, revealing his throbbing cock. She takes it in her mouth, tasting him, before straddling him and sliding down onto his length. The room fills with their moans and the wet sounds of their bodies joining.
