For example: eyes rolling back, uncontrollable moaning, body convulsions, hips thrusting without conscious intent, precum, pussy/asshole clenching around nothing, gritted teeth, panting, gasping for air, crying, twitching, grunting, groaning, whimpering, drooling, cock twitching, legs shaking, leaking fluids, etc. At orgasm: squirting, clenching, cock jumping/twitching, cumming without touching or being touched, convulsions, eyes rolling back until only the whites are showing, swearing, etc.
