This story has a lot of nasty things and is completely unrealistic, so if you were looking for something either less degrading or more plausible, look somewhere else. As usual with this series, it involves copious amounts of piss and inflation.
This has been, by far, the happiest day in my used toilet life.
Nina and Master are getting married! And I get to be the party's special flesh urinal!
The service has been wonderful. Nina was dressed in a wonderful white G-string, with a beautiful "CUM DUMP" embroidered on the spot that covers her ashy blonde bush. Her body was covered in obscenities written by different friends and guests before the celebration. Master had written first, right in the middle of her chubby belly "MARRIED FAT FUCKDOLL". Other obscenities had been written on the rest of her body, so many that it was hard to decipher at times. After a very inspiring sermon about the duties of husband and wife, the priest was getting to the most important part.
"Do you want... to marry Nina the Cum dumpster?" asked the priest to Master.
"Yes, I do," answered Master.
The priest turned now towards Nina.
"Do you Nina, the Cum Dumpster, want to marry...?" he asked of her.
"Yes, I do," she answered.
She was so glad she wanted to cry; I could see it. When you live with someone as long as I have lived with those two, you get to understand them pretty well. She had been throatfucked and bukkake'd by Master's groomsmen 30 minutes before the wedding, so to a person that was not as close to her, the reddening of her eyes might seem just an aftereffect of being abused as she had. But no, let me tell you. Those were not your classic

kind of tears. These were tears of joy.
"Hey, come here toilet. On your knees and open your mouth," whispered someone from the third line. It was Nina younger brother, a 19-year-old kid. A bit spoiled and annoying, if you ask me. Only a brat like that would ask me to swallow his piss in the middle of such a moment. I did as I was ordered though. A toilet doesn't reply, it just takes what is thrown into it. I sat beside the kid, and he shoved my head on his unbuttoned pants. I took his whole dick without a gasp. He started urinating down my throat while the priest was still talking.
"Do you accept that your wife also has a duty, to be a public fuckhole?" the priest asked Master.
"I do, and I cherish it," he answered.
"Do you accept that, as well as your duties as a wife, you will never abandon your purpose in life, which is to be a public jizz tank?"
"I will always be everyman's fuckhole and cumrag," answered back Nina.
I was curious to see their face whilst they made those pretty unconventional vows, but at that moment all I could see was Nina's brother's pubic hair sticking a bit too much in my eyes. Jeez, this was a long piss. I could also tell, don't ask me how, that it was a pretty pungent and very yellowish piss. It's from the way it mixes with other people's piss, it kind of bubbles in my stomach. Later I had pretty nasty burps, and the fault is most likely this young man's. This kid did not drink a lot of water since he woke up. Sometimes it's on purpose, but I think this boy is not that bright anyway, to come up with such a nasty plan. When I finished I gasped for hair and resumed watching the marriage. As I raised myself to watch the scene, Nina was sucking the Priest's cock.
Yikes, what a tramp, right in front of her husband.
A man tapped my shoulder. I turned and saw it was a friend of Master, Vincent. Vincent is pretty much one of my closer friends at this point. Who am I lying to? I actually have a pretty heavy crush on Vincent, and he is in love with me too. He comes at least once a week to watch some trash Japanese show that he and Master have been watching since they were teenagers. Nina and I refuse to learn its name. He has made use of my services thousands of times, and is the only man, together with Master, that can tolerate my stink for longer period of times. Often, during summer nights, he has slept with me outside in the garden house close to Master's villa, hugging me, resting his head on my little breast, or on my inflated belly. More recently, with Master's approval, I have actually gone to his house to have what one would call normal dates.
"Come sweetie, I need to leak," he said in a low voice.
"Sure. Can you fill me in the ass though? I don't wanna miss the scene," I asked him.
"No problem, Sally. I took one of those pills though, just so you know."
"No issue, I will have to take off my jeans anyway," I told him.
I stood up and sat on his lap. Without making too much noise and taking the stage from Nina (now clearly finishing the priest), Vincent slid his cock into my bum and pistoned immediately a huge, huge amount of urine into my body. That is what the pill does. It makes you piss like a fountain, both in pressure and in. My belly felt it immediately.
"AAAAH" screamed the priest, taking his cock out of Nina's mouth. He came onto her face, shaking as he stroked the last few hits. A massive jelly load, from the look of it.
My belly was getting heavier, I had probably already a bunch of kilos of piss in me by the time Nina had stood up to get closer to Master.
"You can kiss your public cumrag wife now" said the priest, still in shock from what was probably the best blowjob he had ever received.
Nina and Master started making out furiously, the priest's cum leaking on Master's mustache.
Tears started forming in my eyes. I was moved by the scene. Vincent took the tear, put it in his mouth, and kissed me. I knew my breath was quite nasty, but he was used to it.
"Beautiful scene, isn't it?" he asked me, once he was finished kissing.
"Yes, beautiful. I am so happy for them," I answered.
The service was finished and so we were asked to leave the building. As I stood up, I realized I had forgotten one very important item. I did not bring my set of buttplugs, the one I use mostly to keep the piss inside. Fuck.
Nina and Master were going down the aisle, reaching the door, and leaving. I had to be with them outside!
"Vincent, I have to stand up and get outside to be with the two lovebirds, but I forgot my plugs and I don't want to shit piss in this place."
I do have some sort of respect for God's House.
"Ok, I'll help you," he said.
I stood up, my belly already looking like I was 7 months pregnant. Vincent helped me. He got on his knees and took my jeans off.
