My stepsister sucks my 20cm cock, amazing deepthroat

Standing in the doorway, I watch as my petite stepsister kneels before me, her luscious lips wrapped tightly around the head of my 20cm cock. She takes it deep, her throat stretched to its limit, making the most seductive gagging noises that send shivers down my spine. Her hands grasp at my thighs and pull me closer, begging for more. As she works her magic, my cock throbs in response, pulsing against the velvet walls of her mouth. It's an erotic sight to behold - her perfectly shaped breasts heaving with each passionate thrust of her head. My heart races as I feel the familiar ache in my balls building up. With one powerful thrust, I bury myself to the hilt in her tight, hungry mouth, and she takes it like a pro, letting out a moan that sends a shiver up my spine.
