One partner looks noticeably bigger or smaller than the other, and the art leans hard into the height, muscle, and body-mass contrast in every panel. Sex scenes usually play up dominance and helplessness, with huge hands pinning, a thick cock looking obscene against a smaller body, and positions that highlight how easily the bigger one can manhandle and fuck. The vibe ranges from playful “tiny vs. giant” teasing to straight-up power fantasy with size as the main kink.
