The strongest "Do It Yourself" teacher, Momoka Ogawa, teaches today's class on "First Anal Sex"! The student, Momizuki Shion, has a slender peach-colored buttocks with a tightly closed virgin anus. As she is extremely nervous, the teacher first demonstrates. The teacher quickly inserts her finger into the anus and cums instantly! Encouraged by the teacher, Shion inserts a silicone dildo for anal sex. However, she only shrinks from the tip of the penis, so the teacher practices anal sex! The teacher makes her cum with a cunnilingus and then penetrates her anus comfortably. In front of Shion, who looks into the combination part, the teacher whispers gently, "It really feels good". Will Shion be able to penetrate her anus?!
