[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 (Censored)

<p>When My Parents Remarried, I Suddenly Got A Gal Sister! Moreover, since my room is the only child&#39;s room, I decided to use it jointly. I&#39;m worried... A hurtful word, &quot;Dassa...&quot; in a room full of otaku. But this older sister was actually quite a tsundere! I&#39;m a virgin, and I&#39;m too small to make a brush down as if to mock me, or to suck my cock when my parents aren&#39;t around! An older sister (Gal) and a younger brother (Otaku) who have different clothes, personalities, and hobbies live together in an incestuous way!</p>
