In the sterile, UV-lit hospital room, a doctor meticulously analyzes a sample of creamy, white semen under the microscope, his eyes gleaming with lust. He strokes his massive cock, fantasizing about the nurse's eager mouth and tight pussy. The doctor's thick shaft pulses as he masturbates, his pre-cum mixing with the specimen on the slide. He groans, his body tensing as he unleashes a torrent of hot cum onto the slide and his hand, leaving a sticky mess that he eagerly licks clean.
