A seasoned gym instructor, craving a change from routine, spots a young, eager babe working out. He guides her through some private exercises, his eyes lingering on her curves. She notices his growing bulge and, with a sultry smile, drops to her knees. He unzips, revealing a thick cock that she hungrily sucks, her inexperience evident but thrilling. He bends her over a nearby bench, slapping her ass before driving in hard. She moans, taking every thrust, her pussy gripping him tightly. He pulls out, his cock coated in her juices, and she eagerly takes him back in her mouth, bringing him to a pulsating climax that leaves her face glazed.
