"People make fun of me because I have big boobs. What do you think, teacher?" A hidden treasure is hidden in this plain and unremarkable girl! The tutor tells the shy Miu that big boobs are a good thing, touches her breasts to check their size, makes her stroke his cock between them, applies oil to check their sensitivity, and stirs up her dripping wet pussy with his cock to teach her about the male body, enjoying the plump big boobs of this plain, obedient and innocent student!
