“back humping” follows a married woman who books a private hotel suite for one reason: to film herself for her long-distance lover. Rose petals scatter the bed as she lights candles and presses record. Wearing only crimson lingerie, she narrates every touch, every moan, knowing he’ll watch “back humping” a thousand times. The camera captures the moment she loses control, back arching, thighs trembling, voice breaking as she begs him to come home. “back humping” is pure aching devotion in motion.
