After a steamy session of ass worshiping and teasing, my curvy step-sister finally gave in to my relentless advances. She bent over, presenting her juicy ass for me to take a ride. I wasted no time, plunging my throbbing cock deep into her tight hole. The sight of her fat, natural tits bouncing as I drilled her from behind was enough to drive me wild. Her moans of pleasure echoed through the room, fueling my lust. But the fun didn't stop there. I had a trick up my sleeve. I pulled out just in time, covering her ass with my hot load. The sight of her dripping wet and satisfied was the ultimate reward. But the show wasn't over yet. She eagerly took my limp cock in her mouth, sucking it until it hardened once more. We continued our wild romp, exploring new heights of pleasure. As we reached our climax, she revealed her true colors, teaching me the art of withdrawal. What a perfect way to end a perfect session.
