Leo's appointment with Dr. Toppinbottom started innocently enough, but the doctor's gaze kept drifting to Leo's crotch. 'Leo, I need to check something,' he said, his voice hoarse. He lubed up his fingers and slowly inserted them into Leo's tight hole, making Leo gasp. 'You're very responsive, Leo,' the doctor commented, his own bulge growing. He couldn't resist any longer, pulling out his hard cock and pushing Leo's legs back, sliding into him with a sigh. 'This is a different kind of physical, Leo,' he said, thrusting deeply into him.
