Due to my parents' remarriage, I suddenly got a gal sister out of nowhere! And since there's only one kid's room, we have to share it… Fuck, this is nerve-wracking… In my otaku-filled room, she says 'Lame…'. But this sis, she's actually quite the tsundere! She makes me lose my virginity as if mocking me for being a virgin, and when our parents aren't home, she even gives me head. My sister (gal) and I (otaku) live together in an incestuous cohabitation with different tastes in fashion, personality, and hobbies!
