Confident female doctor Rena. Her alluring, radiant skin hinted at her voluptuous figure even beneath the white coat. He had first met her during college, in the same club where they engaged in sexual activities under the guise of drinking parties, and she had participated willingly. The urge to have her again still burns inside him. At first, he blackmailed her using secrets from the past, and she looked at him with contempt—but gradually, her gaze transformed into one of obedience, like a servant submitting to his master. Now, she has become a lustful sow, craving sexual submission and finding pleasure as she's ravaged by an enormous cock. He can never go back to the way things were. *This work is a re-edited version of "Female Doctor in... [Blackmail Sweet Room]" (Product No: vdd00120).
