A useless part-timer who can't do his job gets yelled at by the store manager and is treated coldly by the office worker. But when he helps the office worker — the beautiful married woman “Mizuki” who had been distant — they unexpectedly fall into an affair. The two sink into sex driven by her marital trouble and sexual desire. They have nonstop sex at the store and at her parents' home while her husband is away, writhing with repeated orgasms in creampie sex.
