Dr. John, an experienced physician, finds himself in a unique situation when two of his patients, eager young men, start an impromptu jerk-off session in his office. He decides to turn this into a lesson, demonstrating the art of anal play. With the first boy, he shows how to tease the hole, using fingers and toys, before pushing a thick dildo deep inside. The second boy watches, eager for his turn. Dr. John takes charge, sliding a fat cock into the boy's tight ass, pounding him hard while the first boy sucks his own dick.
