An incredible gal sister invites you with dirty talk

Rika, a devilish gal sister who has become a high school girl, is very interested in erotic things! I've started studying dirty words to seduce you (brother) my beloved one! When I find you anywhere in the house, they will approach you with a very obscene verbal abuse! They burst into the bathroom, sneak into the bedroom, invite them into their own room and invite them in lewd clothes! "Big brother... you're a real pervert when you have a baby with your younger sister♪" With provocations in gal language, you get drunk on the sex you've just learned!
