Ma Chao, a 28-year-old single office drone, discovers that every time he climaxes and ejaculates, his soul randomly jumps into the body of a nearby creature that is also climaxing. From his female coworker Xiao Lin, to a bitch dog, to his buddy's girlfriend, to the gluttonous Liangzi—each jump is more humiliating and perverse than the last. He enjoys it while falling apart, swearing off lust one moment and unable to resist going for another round the next.
