An ordinary couple living a peaceful life... One day, a group of men from a plumbing renovation company come to their house to check the meter. The young, quiet, slender wife with short black hair and glasses, who is quiet and reserved, is subjected to endless "pursuit pistons" by the two sweaty workers during the day while her husband is at work, and she shows off her embarrassing orgasm face over and over again. "Ahhhh, I'm already cumming...!"
