A woman is noticeably bigger than her partner, whether that means taller, thicker, more muscular, or straight-up giant-sized, and the art leans hard into the size gap. Sex scenes often play up her physical advantage with rough riding, pinning him down, face-sitting, or just using her weight and reach to control the fucking. The vibe ranges from playful amazons to full-on power fantasy where the smaller guy looks totally overwhelmed.
