Miki-sensei is a private tutor who kindly teaches him how to study. He asks for advice on everything from studying to love, and then asks for advice on premature ejaculation. He embarrassingly begs the teacher to help him improve his premature ejaculation. He gets excited by the big-breasted teacher and ejaculates prematurely! But his dick doesn't go soft, and the teacher gets excited too! He says it's wrong, but he accepts the penetration, even though he's embarrassed. We deliver it to you from a safe hidden camera angle.
