An innocent twink's routine check-up takes a steamy turn when the doctor can't keep his hands off the boy's uber-cute, plump ass. Slipping on a glove, he lubes up and gently pushes his throbbing cock into the tight hole, causing the twink to whimper. The doctor's experienced thrusts soon have the boy begging for more, his own cock rock hard and leaking pre-cum as he's stretched and filled like never before.
