The gym, usually echoing with grunts of exertion, now resonates with the crack of leather on flesh and Bella Wilde's desperate moans. Bobbi Starr, a formidable dominatrix, has Bella bound to a weightlifting machine, her arms stretched wide, legs spread, pussy and ass fully exposed. Bobbi, her body glistening with sweat, methodically whips Bella's ass, each lash revealing more of Bella's pink, inner flesh. Bella's cries grow louder, her body writhing, as Bobbi alternates between whipping and fingering her wet cunt, driving Bella to the brink of madness.
