After hitting the jackpot, I knew exactly how I wanted to spend my winnings. I'd been saving up for years, dreaming of the day I could buy my step-sister the ultimate pleasure. I knew she'd been craving a deepthroat blowjob and a monster cock, and with my newfound wealth, I was ready to make her dreams come true. I started by giving her the deepthroat blowjob she'd been yearning for, my tongue dancing over her clit and my throat filling with her sweet taste. Then, I unleashed my huge cock, throbbing with anticipation. I took control, my hands gripping her throat as I plunged into her, each thrust sending waves of pleasure through both of us. The snow outside was a perfect backdrop as we indulged in our wildest fantasies, our bodies entwined in the heated embrace of our passion. As I continued to pound her, she met me stroke for stroke, her moans echoing through the room. The sight of her big ass bouncing and gagging on my cock was a sight to behold, a testament to the power of lust and desire.
