BLK-306 Rika Mari, a ridiculous gal sister who invites with dirty words

Little devil gal sister “Rinatsu” who became a school girl is curious about naughty things! I started studying dirty words to seduce my favorite you (brother)! If you find you anywhere in the house, you will approach with too obscene word blame! You can break into the bathroom, sneak into the bedroom, or invite them into your room and invite them in a nasty look! “Older brother … It’s a real metamorphosis like making a child with my sister ♪” While provoking in Gal language, I get drunk with the SEX I just learned!
