先生、どうしてそんなに私をムラムラさせたの?

My hot and naughty teacher invited me to her house to have private lessons, I'm a pure student and I was thinking that I would only have lessons about the human body when I got there she took off her clothes and made me fuck her big pussy saying that I'm a boy very bad, I then sinned, I put my dick out and fucked her big, fat and delicious pussy, I was always very horny for her
