The house is quiet, their stepmom out. Emma Starletto and Kyler Quinn find themselves alone, the air thick with unspoken desires. Emma, in a tight tank top and short shorts, flops onto the couch, her big tits bouncing. Kyler enters, trying to hide his growing bulge. Emma's eyes flick to his crotch, then back up, licking her lips. "You're hard, Kyler," she observes, a challenge in her voice. Kyler swallows, his cock throbbing. "And you're wet, Emma," he counters, noticing the damp spot on her shorts. Emma grins, standing and straddling him, her pussy grinding against his hardness. "So, what are we gonna do about it, big brother?" she purrs.
