Sayu, a serious type of girl from the music university's attached school. She is tall and slender, and she wears a rare vertical-lined old-style swimsuit, K-●S 5●33. The material feels a bit outdated, but the white lines running from her armpits to her thighs accentuate her slender figure beautifully. Despite her lazy and unmotivated aura, she gets extremely wet down there with just a little breast stimulation.
