Metal-bodied characters show up as the focus, ranging from sleek androids and sexbots to bulky machines with obvious joints, panels, and glowing eyes. Scenes often lean into the contrast between hard mechanical parts and soft flesh, with dicks, pussies, and asses getting fucked while cables, ports, or built-in toys add an extra kink angle. Artists usually highlight chrome shine, exposed circuitry, and the cold, inhuman vibe mixed with very human lust.
