My tsundere little sister tempts me with her spring outfit every day. (Kano Yura SSNI-308)

She loves her brother so much that she pretends to accidentally peek at him every day to seduce him! She pretends to be asleep while saying "What are you looking at?", using her body parts to seduce him! Her brother, having reached his limit, retaliates, making her gasp and moan even as she resists!
