GDHH-062 "Hey, Big Brother? Is There Something Strange About My Body...?" My Sweet, Innocent Schoolgirl Sister Will Ask Me About Absolutely Anything, But Today She Came To Me With The Sexiest Question I've Ever Heard.

My Younger Sister Is A High School Girl And She's Very Pure, And If There's Something She Don't Know, She'll Ask My Older Brother... But Today, She Suddenly Showed Me Her Tits, Touched Her Pussy, Made A Serious Face, And Asked A Super Erotic Question. I'm coming! Apparently, she seems to be suffering from the growth of her body, which is peculiar to puberty. Then, my sister looks serious and is curious about the erection! I pretended to give sex education seriously and ended up with her sister.
