In this scene, the petite stepsister, Lisa, is caught masturbating by her stepbrother, Mark. He approaches her, grabbing her hair to force her to look at him. "I always knew you wanted my cock, Lisa," he sneers. She's trembling with anticipation and fear as he pushes her to her knees. "Suck it, stepfucker," he growls, thrusting his erection into her open mouth. Her mouth is stretched around the thick shaft, taking it all as she bobs her head up and down. Lisa's hands explore her body, pinching her nipples as she sucks harder on his cock. Mark groans in pleasure and roughly shoves two fingers into her tight pussy, filling her up. "You're such a slut," he moans, pulling his fingers out to cum all over her face. Lisa' couldn't believe he actually called her that, but the warmth of his cum on her face made her shiver with excitement.
