A curious twink finds himself in a gay clinic, eyes wide with anticipation as the nurse hands him an oil thermometer. With a mischievous grin, he lubes up the long, thick glass rod and spreads his ass cheeks. He teases his tight hole with the tip, gasping at the cold, smooth intrusion. Slowly, he pushes it deeper, his breath quickening as he imagines it's a rock-hard cock filling him up. He fucks himself with the thermometer, his moans filling the room until he can't hold back any longer, cumming hard as the thermometer reaches its limit.
