In the sterile, clinical setting, Nurse Rozy dons latex gloves, her eyes gleaming with mischief as she prepares a large needle. The patient, bound and vulnerable, squirms in anticipation. The nurse's fingers trace the curve of the patient's ass, spreading lube, priming the area. With a swift, practiced motion, she inserts the needle, the patient's gasp echoing through the room. She injects, the ass cheek visibly swelling, the patient's moans growing louder, more primal.
