She's on all fours, her ass up in the air, and he can't resist the sight of her. He kneels behind her, his cock already hard and ready for action. He grabs onto her hips and enters her from behind, feeling her tight pussy clenching around him as he starts to pound into her. She moans with pleasure, feeling his balls slapping against her clit with each thrust. He reaches around and starts to play with her nipples, making her moan even louder. She pushes back against him, taking him deeper and deeper inside of her. He pulls out of her for a moment, flipping her over onto her back. He spreads her legs wide open and enters her once again, pounding into her with abandon. She wraps her legs around him, pulling him in closer as she feels herself getting closer and closer to the edge. He can feel himself getting close to the edge as well and he pulls out of her once again, flipping her back over onto all fours. He enters her from behind once again, pounding into her with all of his might until he finally reaches his climax. They both collapse onto the bed, exhausted but satisfied. As they lay there catching their breath, she looks back at him with a sly grin and says, "That was some hot doggy style fucking."
