Miki Arakawa, the luscious Japanese dental nurse, can't resist her urges any longer. Her massive, bib-adorned breasts strain against her uniform as she fingers herself, her moans filling the clinic. When a patient enters, she doesn't shy away. Instead, she mounts him, her big tits bouncing as she rides him in cowgirl position, her tight pussy gripping his cock. The bibs, once a symbol of professionalism, now sway and slap against her skin, adding a lewd, forbidden touch to their fucking.
