Nadia White, in a sports bra and tight leggings, turns up the heat on the treadmill, her eyes fixated on Cali Kastro's bulge. She pauses the machine, her heart pounding, and reaches out to stroke his growing erection through his shorts. Cali, unable to resist her allure, springs free, and Nadia hungrily takes him into her mouth, her head moving in sync with the treadmill's motor. She moans around his cock, the vibrations sending shivers down Cali's spine as he watches her workout in more ways than one.
