My sister-in-law, who suddenly appeared, is extremely cute, but on the first day she came over, she asked me if I liked sex, saying, ``I...I love sex.I want to do naughty things all day long!What about your brother?'' A female student who loves extreme sex! I wonder if it's okay because we're not related by blood.As soon as I got home from school, I said, ``Mommy's coming home, so hurry up.''
