MBRK-008 Kasumi Tsukino, the older sister of my girlfriend, is a seductive slut who enjoys situations that would be dangerous if she were found out

I’ve been dating my girlfriend, Miu, for two years. Lately, at her request, I’ve been spending more time at her house, almost living with her, but her older sister also lives with us. Even though her older sister, Kasumi, knows about my relationship with Miu, she still teases me sexually… I think I’m starting to lean towards the naughty, slutty older sister who seduces her younger sister’s boyfriend… #Dirty-talking slut #Sweet-smiling bad girl #Dangerous situation #Whispering
