Housewives go on a trip to a hot spring to get some time off from housework and childcare. Of course, they secretly harbor a faint hope in their hearts. While these wives are taking a bath, a group of men with erect penises arrive! Surrounded by penises and with no way to escape, the wives rub their erect penises all over their bodies, ejaculating in large quantities one after the other! The wives' small desire to cheat is perfectly sublimated as they are treated like sex toys to be fucked as much as they want.
