The clinic is abuzz with the sounds of moans and slurping, the scent of disinfectant mingling with the musk of arousal. Ryan, his eyes wide with anticipation, approaches the next patient, a rugged, silver-haired man. The man's cock, already hard, tents the thin fabric of his gown. Ryan, playing the role of the eager student, reaches out, his fingers tracing the outline of the man's shaft. He leans in, his breath hitching as he tastes the man's precum, the salty flavor exploding on his tongue. The man groans, his hips jerking forward, eager for more of Ryan's attentive care.
