Ava Sinclaire's boxing lesson takes an unexpected turn when she meets her friend's brother, a muscular, pierced hunk with a raging hard-on. He can't resist her tight, athletic body, and she can't ignore his throbbing cock tenting his shorts. They move to the locker room, Ava stripping off her sweat-soaked stockings and top, revealing her luscious, big natural tits. She jerks him off, then takes his thick cock into her mouth, gagging on his length. He pins her against the lockers, fucking her hard from behind, her big ass bouncing against him as she moans in pleasure. They switch positions, Ava's tattooed body writhing as she grinds on his cock, both chasing their explosive release.
