In a cramped, clinical setting, a doctor twink takes command, his eyes gleaming with kinky intent. He instructs his shy, straight patient to turn around, exposing his toned, bare ass. The doctor lubes up, pressing his slippery fingers against the patient's virgin hole. The patient gasps, tensing at the unfamiliar sensation. The doctor reassures him, his voice low and soothing, as he begins to stretch the tight entrance. He teases and probes, building up the patient's desire. After a while, he stops, instructing the patient to turn back around. The patient complies, his cock thick and hard, pre-cum leaking. The doctor smiles, wrapping his skilled hand around the shaft, expertly pumping and twisting until the patient's body shudders, and hot cum spills out, coating his hand.
