KTRA-496 I asked my sister who's going through puberty if she wants to have sex. Manatsu Misaki

Lately, my little sister is so cute I can't stand it... My brother who has completely made his little sister a target of lust really wants to do perverted things with her! In a mischievous mood, I showed an erotic book to my pubescent little sister, and what do you know? She seems to be getting excited. Maybe there's a chance! 'Want to have sex with your big brother?' Confused by her brother's perverted statement, the little sister was at a loss, but her pubescent body was honest. Little by little, the little sister also started to feel horny...!?
