BLK-627 A play’s room is shared with a gal sister (showy, cold, erotic) who was made by her parents’ remarriage! I Was Trained Every Day By A Tsundere Slut… Luna Tsukino – Tsukino Luna

When My Parents Remarried, I Suddenly Got A Gal Sister! Moreover, since my room is the only child's room, I decided to use it jointly. I'm worried… A hurtful word, "Dassa…" in a room full of otaku. But this older sister was actually quite a tsundere! I'm a virgin, and I'm too small to make a brush down as if to mock me, or to suck my cock when my parents aren't around! An older sister (Gal) and a younger brother (Otaku) who have different clothes, personalities, and hobbies live together in an incestuous way!
