7-9: Keeping the same position, you move inside of Nadia. She cums, while you don't cum.

You feel Nadia roll her hips on your lap, coating your dick with her juices. Then you grab her hips, holding them in place, and start to move your hips against hers. You start off slow, feeling how well her pussy has adjusted to your size. Nadia looks into your eyes, alight with pleasure, only for them to close, when you start to increase the pace, making her throw her head back, and cry out in pleasure. You watch her breasts bounce, pulling her closer to you, so that you can feel her nipples brush against your chest. Whenever you accidentally slide out, you brush the tip of your dick against her pussy lips, then slide back in. As you drive her closer to cumming, she tightens her grip on your dick, and gasps even more, begging for release. For awhile, you don't let her cum, continuing to move inside of her at a hard, deep, fast pace. Nadia begs to cum now, her body starting to glisten with sweat, as she tries hard to not cum yet. Then you let her cum, feeling her cum hard, as she gasps hard. She clings to you, feeling her pussy milk your dick, coating it with more of her juices.
