I haven't seen any such movies, but I've seen something similar, where the lady was on top of the guy in the cowgirl position. She bent the guy's cock to increase its contact with her clitoris and used quick, jerky movements with her hips to bring herself to orgasm with his cock.
Having the lady on top is more visually appealing in porn movies, because the lady basically ends up twerking her ass a lot to make herself orgasm with the guy's cock, instead of the guy twerking his ass on top of her. Of course, this kind of thing depends on your preference. Many women, who watch porn, would rather see the guy twerk his ass.
But I've seen only one such scene in a compilation film a long time ago, and I have no idea where to find it now.
