A very ordinary couple living a peaceful life... One day, a group of plumbing renovation workers come to their house for an inspection. The quiet, introverted, slender young wife with short black hair and glasses, who is home alone while her husband is at work, is repeatedly subjected to endless 'assault pistons' by the two sweaty workers, exposing her shameful ecstasy face over and over again. 'Ahhh, I'm cumming already...!'
