Petite blonde Amber and her stepbrother, Marcelo, cram for an upcoming test, but their casual conversation turns heated as Marcelo's eyes linger on Amber's tiny frame. She innocently licks her lips, drawing his gaze to her mouth. He nonchalantly adjusts his big dick in his pants, hinting at his desire. Amber, with her small hands, begins to stroke Marcelo's thick cock, taking it deep into her throat, gagging slightly. Marcelo holds her head, fucking her face while they discuss calculus. Whitney OC, their other stepsister, enters, catching them, but Marcelo, unfazed, tells her to join. Whitney hesitates, then takes her place, letting Amber suck her pussy while Marcelo continues to use her mouth.
