Master's classroom is far from conventional, with desks replaced by sprawling beds and chalkboards by mirrors reflecting every intimate action. Today's lesson sees the schoolboy, timid yet curious, kneeling before Master, his mouth stretched wide to accommodate the older man's thick, pulsating cock. Master's thrusts are his lesson plans, each one driving deeper, teaching the boy the art of giving head, until he's gagging and dripping, a master pupil in the ways of gay lust.
