Little demon sister Shuri has become a schoolgirl who is very curious about naughty things! I started learning dirty words to seduce my favorite friend (brother)! If they find you anywhere in the house, they will approach you with obscene words! Come into the bathroom, sneak into the bedroom, invite into your room and invite with a nasty look! "Brother... do you want to impregnate your sister? You're such a pervert♪" While provoking with gal language, you will be intoxicated with the SEX you just learned!
