Nina Nova, the fit stepsister, returns home from a rigorous workout, her skin glistening with sweat and her heart pounding. Her stepbrother, hidden, watches her stretch, her natural tits straining against her sports bra. Catching him, she teases, "You like what you see, bro?" He admits, "Fuck yeah," and she grins, "Well, come help me work off this... energy." She rides him, her pussy clenching around his cock, her sweat dripping onto his chest.
