Ichika is asked to try on underwear at an underwear store run by the wife of her husband's boss, Tabuchi. Tabuchi comes when her husband is away, asks for her impressions of trying on clothes, and forcibly rapes Ichika. After that, Tabuchi visits Ichika frequently, and while her husband is passed out, he lets her husband go on a business trip and does whatever he wants to Ichika. Ichika drowns in numbing pleasure from his relentless caresses.
