Imouto na Noni...... Oniichan no Shisen ni Yokujou suru Atashi
"Looks like my brother is a pervert."
Hanane spreads her legs provocatively, rolls up her skirt, and shows her steaming wet panties to her older brother, Akinari.
One day, Hanane came home soaking wet from the rain. She was changing in her room, when she noticed that Akinari was peeking through the crack in the door.
Hanane was not disgusted by his hot gaze. Actually, it kinda turned her on.
