A doctor, a burly, hairy bear, takes two fresh-faced twinks under his wing, promising to educate them in the ways of gay pleasure. He begins with a physical examination, his large hands exploring their lean, toned bodies, making them gasp and shiver. He runs his fingers over their assholes, making them clench and moan. Then, he introduces them to the sensation of a cock in their mouths, guiding them as they suck him off, teaching them the art of pleasuring a man. The twinks, hungry for more, take turns deepthroating the doctor, their enthusiasm growing with each bob of their heads. The doctor, pleased with their progress, rewards them with a taste of their own medicine, fucking them raw and hard, teaching them the joy of bottoming.
