The allure of the Nike Pro-clad fitness model is too much for the hidden observer to resist. They push up against her, their cock straining against their pants, seeking friction against her plump, sweat-slicked ass. The model, initially startled, quickly succumbs to the primal rhythm, her own hand snaking down to rub her aching clit through her Nike Pro shorts. The dry humping grows more intense, their bodies slapping together in a symphony of wet, desperate sounds, her moans echoing through the empty park as she nears her climax.
