A high-school graduate with big tits comes to an all-male factory and gets fucked by a hard-working power fucker! She gets her big tits out of her loose work clothes in front of me, her instructor... and when I make her cum all over the place, I succeed in turning her into a Nakadashi pet! However, she is later cuckolded by the evil boss who finds out about it... and proposes to have a continuous Nakadashi threesome with her!
