The step-sis wakes early, her pussy already throbbing with desire. She finds her stepbrother in the kitchen, his back turned as he pours coffee. She sneaks up behind him, dropping to her knees and taking his big dick into her mouth. He groans, surprised but thrilled. She sucks him roughly, her big tits pressed against his legs, her hands squeezing his ass. He can't help but fuck her mouth, his hips moving in rhythm with her sucking. He cums hard, his hot, thick load filling her mouth. She swallows, then licks her lips, a satisfied smile on her face.
