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