Rubbing My Huge Dick on My Stepsister

After a long day, I was lounging in the living room when my stepsister walked in wearing nothing but a pair of tight shorts and a thin top. She looked so good that my cock immediately hardened, straining against my pants. I couldn't take it anymore. I pulled down my zipper and freed my huge dick, stroking it a few times to keep it fully erect. The thick veins stood out, and the head was slick with precum. Slowly, I moved beside her. She was lying on the floor, scrolling through her phone. I positioned myself next to her and pressed my massive cock against her thigh. She flinched but didn't pull away. I started rubbing my big dick against her, dragging the shaft along her leg, then up against her hip, and finally pressing the swollen head right against her shorts. She could feel how huge I was. I gripped her waist and ground my cock hard against her, back and forth, letting her feel every inch. Her breath hitched, and she moaned quietly. I kept rubbing my huge dick against my stepsister, loving the warmth of her body through the thin fabric.
