She loves her big brother so much that she pretends to be careless, flashing her panties every day to seduce him! From wedgies visible under her uniform to stained panties, she says "What are you looking at~" but her tsundere nature shows as she pretends to sleep just to tease him with panty flashes! When her brother's excitement reaches its limit and he counterattacks with insertion, this dishonest tsundere little sister resists at first but eventually accepts it, moaning cutely! Please imagine yourself as the big brother and enjoy Yura Kano's first seduction work!
