That JAV

My parents remarried and I, who was a shady kid, suddenly had a gal sister! And since my room is the only room for the kids, we have to share it.... I'm worried... I've been told "Dassa..." in my room, which is full of wotaku activities, which hurts my feelings. But this sister is actually quite a tsundere! She is too much of a little devil, letting me have a brush with her as if she was mocking my virginity, and sucking my dick when my parents are not around! The sister (gal) and brother (otaku), who have different clothes, personalities, and hobbies, live together in an incestuous relationship!
