It was a difficult position to maintain, on his feet with his knees braced against the edge of the mattress, pounding into her in steady rhythm that he knew would bring her to a deeper, more prolonged orgasm... because he'd experienced it himself, the feedback loop of her pleasure driving his own to something he never could've achieved without her. Having no idea that it was possible for a woman to have different types of orgasm, they'd spent a great deal of time learning together.

It was easier, sometimes, to do this with his hand, long fingers curled inside her, driving upwards towards her navel until her cunt spasmed and became almost alarmingly wet, but at this angle, with her spine bowed and her pelvic tilted just right, he had confidence that it would work just fine.
