Six young wives who have no sex with their husbands. Their enjoyment, like in their student days, is sweating it out in volleyball while wearing bloomers. The practice time spent sweating with the young male coach who is guiding them is supposed to be a valuable stress relief! But... the stress of the young wives who have been sexless for a long time can no longer be relieved by sports alone! Rather, sex with the male coach than volleyball!! They intentionally stick their bloomer butts to the coach more than necessary, have him touch their breasts, and just induce the coaches to get erect! And then, if they get erect, they attack them all at once! Each of them unleashes their accumulated sexual desire on the coach's dick, squeezing out sperm and making them ejaculate into their bloomers! Because they were originally athletic club girls, their sexual desire is bottomless! They drain the coaches with their overflowing stamina!
