Sumire, a young, innocent-looking Japanese girl in her school uniform, finds herself in a compromising position. She's on her knees, her uniform skirt hiked up, revealing her white panties. She's nervously holding a large, rock-hard cock, her small hands barely able to wrap around it. She tentatively starts to lick it, her tongue exploring the unfamiliar terrain, her cheeks flushing a deep red. She's a virgin, but she's eager to learn, to please, and her innocent curiosity is strangely arousing.
