A hung, tattooed muscle dude takes center stage, his thick cock throbbing with anticipation. A naïve twink, fresh and eager, joins him, eyes wide with curiosity and excitement. The muscle dude, a self-proclaimed 'gay sex doctor,' begins the lesson, guiding the twink's small hand to stroke his massive cock. The twink, feeling the power in his hand, grows confident, his own cock stirring. The muscle dude then teaches him how to take a big dick, slowly guiding the twink's head down, inch by inch, until he's deeply throating. The lesson culminates in a raw, passionate fuck, the twink moaning as he's filled and stretched by the muscle dude's relentless pounding.
