The evening started off as any other party, with music blaring from the speakers and people mingling, drinking, and enjoying themselves. Amongst the crowd were Amber, a 19-year-old girl, and her girlfriend, Rosie. Both of them were what some people might call 'piss-sluts', which simply meant that they enjoyed receiving and swallowing other people's urine. This was something that they had both discovered during their teenage years and had grown quite fond of.
As the night wore on, more and more people began to venture outside for a cigarette or to relieve themselves. This is when Amber and Rosie revealed their service to the group - they were both more than willing to act as human toilets for anyone who needed it. The girls approached a group of guys, all of them obviously in need of a piss, and offered their services. To their surprise, the men were more than happy to oblige.
One by one, the guys stood in front of the girls, held their erect cocks and let loose with a torrent of piss straight into their open mouths. Amber and Rosie didn't mind at all - in fact, they welcomed the golden shower of warm piss that filled their mouths, making them gag and choke and feel alive with pleasure.
As the night wore on, more and more people joined in on the fun. Women started to line up eagerly, eager to relieve themselves in front of the eager young girls. Some of the women even went so far as to drink their own piss after it had been warmed up by their bodies. It was an experience unlike any other for Amber and Rosie, who had never imagined that they would be surrounded by so much urine and still be enjoying themselves.
There were moments of pure ecstasy, like when they were engaged in a long, intense piss-kiss with two women at the same time, or when they were alternatively swallowing each other's piss and receiving blowjobs from some of the braver guys in the group. There were also moments of pure shame and humiliation, like when they were forced to clean a cock with their tongues after it had ejaculated for the tenth time that night.
By the end of the night, Amber and Rosie were exhausted but exhilarated. Their faces and clothes were stained with piss and cum, their hair matted and tangled from the numerous piss-washes they had endured. Yet, they couldn't help but feel a sense of accomplishment - they had faced their deepest, darkest desires and come out on top. They were two piss-sluts who had survived an extreme piss orgy, and they were all the more proud for it.
