As Miori observes up close, they live up to the rumors, openly drinking each other's urine—licking it from the tips of their toes and creating intensely intimate scenes. The second couple consists of a lesbian novice and an experienced girl who met through a dating site. With curiosity rather than hesitation, they readily engage in piss drinking as a way to test their bond. Despite their shallow connection, they challenge themselves to drink each other's urine, revealing raw and daring moments.
