A school girl who is worried about her youth and the legs of her skirt just by walking. And if you can, your bare feet will be good. If the school girl in front of you climbs the stairs, even if you don't like it, your bare feet are right in front of you. Aren't those whip-whipped thighs too excited? Furthermore, when you see a panchira that seems to be flipping and can't be flipped, and seems to have a one-chan, you think it's a lucky day, don't you? The best thighs and panchira are packed in this staircase school girl.
