Teen in school uniform licking man's crotch

A young girl with long black hair and a school uniform is kneeling beside a man who's lying down. She's licking his crotch while holding his cock with one hand. The man's legs are spread and he's relaxed. She's focused on the task, eyes closed, tongue moving. The setting looks like a bedroom with plain walls. The mood is casual and intimate, no rush or drama. She seems comfortable and confident. The man is mostly passive, letting her take the lead. The lighting is natural, not too bright. There's no music or sound effects. Just the quiet hum of the room and her breathing. The video feels real, like a spontaneous moment caught on camera. The watermark says 'YUZU' and '18tokyo.com/TubeCup'.
