A beautiful, nymphomaniac dental hygienist seduces a male patient under the pretense of giving brushing instructions, and asks for sex even though treatment is taking place on the other side of the partition. Her nipples, hidden under her uniform, are hard with excitement, and the crack between her legs is wet. After servicing each other's genitals and preparing for insertion, they copulate and reach orgasm, even while the clinic is open. They don't care that they might be found out by the rough penetration, as they don't stop copulating, demonstrating their perverted side! *This work is a part of the "Temptation Dental Clinic" This is a re-edited version of " Rui Hiiragi" (product number: 24cmd00030).
