Give her a chance to dominate….
She kneels on top of him, pushing off his chest and sliding up and down his thighs. She can relieve some of her weight from his pelvis by leaning back and supporting herself on his thighs.

For that extra thrill, she can widen her knees or bring them closer to his body in fluid motions.
