Yui is engaged and happily counting down the days to her wedding. But when her disgusting ex-boyfriend suddenly reappears and tempts her, she ends up having sex with him—just once, she tells herself. As their intense physical chemistry reignites, he suddenly asks, "Hey, can I piss inside you?" At first furious, Yui gradually succumbs to the strange, overwhelming pleasure. Moaning, "It's warm... so gooood!" she gurgles as she eagerly drinks his urine, orgasms repeatedly from being drenched in piss, and becomes completely soaked as his urine and cum mix inside her pussy.
