Robby Echo, the rugged American trainer, can't resist the temptation of his tiny teen clients, Madi Collins and Aria Carson. He turns their workout into a fuck fest, appreciating their youthful bodies – Madi's firm, round boobs and Aria's plump ass. He teaches them the art of deepthroating, face-fucking them until they gag. Then, he takes them from behind, filling their tight holes, their moans echoing in the gym. He finishes by fucking their asses, leaving them with a new appreciation for 'freeuse' exercise.
