Peter's wife had left him just before the pandemic, and shortly after that he had lost his job. He'd been making ends meet since then, but his savings were dwindling. He could still make rent next month, but after that he wasn't sure what he would do. Homelessness seemed increasingly likely in his future.
Sharing his troubles that night when he met up with Hal, he was surprised by the calculating look that stole over his acquaintance. Hal was someone he had met online, shortly after Peter's wife had left him. They had both been seeking some kind of sexual outlet. At first they spent a lot of time discussing things they both liked, which included bondage, pain, chastity, and humiliation. Hal greatly enjoyed being dominant, while Peter admitted early on that he was very much submissive. Quite naturally they had settled into a pattern of Peter giving Hal a blow job every time he was in his neighborhood, which turned out to be two or three times a month.
"I might be able to let you rent our basement", Hal offered. "Don't get your hopes up, because I need to check things out with my wife. Now, about that blowjob...." Peter got down on his knees and complied, putting perhaps a bit more effort into his actions than usual if Hal's moans were anything to go by.
It was two weeks before he managed to meet up with Hal again, and his situation hadn't improved one iota. So when Hal outlined his offer, Peter was so excited that he barely listened to what Hal had to say. "I know it's not a great place to live, but at least it's warm and dry and you'll have a home." He went on to describe the place. He would be sharing the space with the furnace and the laundry facilities. It had a dehumidifier so it stayed fairly dry in the summer months, and there wasn't any mildew. There was room for a bed and a small fridge and a hot plate, and if Peter was willing to do some work they could even install a toilet and a shower.
"My wife Jessica was thinking we should charge you $800 per month, but I know that might be more than you can manage, so I have another proposal. Why don't you start sucking while I tell you my idea." Hal had been getting quite hard while he was talking, and Peter wasn't used to starting the blowjob with such a stiff cock. He found it hard to focus on what Hal was saying with his hard cock immediately filling his mouth and threatening to go down his throat. He caught something about his rent being just $200, but also needing to commit to providing daily blowjobs, and doing Hal and Jessica's laundry as well as shoveling snow and doing other household chores and renovations. "You wouldn't be our slave, not really," Hal was saying, "Just earning your keep. Well, except for one thing, and it's really extremely important to me. You see I've always wanted to be able to use a guy's mouth as my urinal. Would you do that for me?" Hal had barely got the words out of his mouth when his cock started pulsing and he filled Peter's mouth with cum.
Peter was taken aback by the thought of serving as Hal's urinal. He had actually tried watersports play before with a girlfriend in university, but found that the reality of tasting her pee wasn't nearly as much fun as he had expected. Hal's offer was otherwise generous, so he didn't know what to say. But, given his increasingly desperate financial situation he realized that he really didn't have much choice, so after he had swallowed and his mouth was no longer filled with Hal's cock and cum he just shrugged and said "Sure", and so it was agreed.
By the end of that month the new toilet and shower had been installed and Peter had moved into the basement. Blowjobs, which had been kind of a fun occasional event, suddenly became a routine daily and sometimes twice-daily chore. Sucking Hal that often was just something that had to be done, and there was never a day off. Hal would come down to the basement, usually in the evening while Jessica was watching her favorite show or out with her friends, and demand payment. Peter made sure to put in some real effort, and swallowed dutifully each time, and if that and the chores had been all that was required of him he would have been quite content. Swallowing Hal's cum and doing his hosts' laundry and a few other chores was a small additional price to pay for a roof over his head and a warm bed at night for such low rent. But the bargain he had made with Hal involved a more humiliating aspect.
The very first night, after Hal had filled his mouth with cum, he had told Peter to wait on his knees, and then when his cock had gone soft, he had proceeded to completely fill Peter's mouth with his piss. It was warm. It was salty. And it was rank. Peter struggled to swallow, with Hal's warning fresh in his mind: he would have to learn to swallow it all, or face eviction. He had been given a week to learn, and while it hadn't been easy, the thought of being on the streets was sufficient motivation that he was able to overcome his inhibition at swallowing another man's urine. He managed to earn Hal's praise before the week was even up.
Hal had, of course, started him off easy. But as Peter continued to master the act of swallowing piss, Hal began using him as a urinal more and more often. After a month he was serving as Hal's urinal twice a day, and by the time fall came he was pretty sure that Hal had completely stopped peeing in the toilet whenever he was home. But Hal wasn't done. Before the first snow he had started filling bottles with his piss at work, and taking them home to pour down Peter's throat, and as Christmas approached, Hal had proudly informed him that Peter had been drinking all of his piss all week long, except for his first pee every morning. "I want you to swallow that too." Hal said, which was why the plan for the bathroom renovation was hatched.
Part of the motivation was that Hal simply didn't want to be troubled with going to the basement just to pee, and this was especially true in the mornings. Instead, he intended to make it possible for him to discreetly use Peter's mouth in the downstairs bathroom. Convincing Hal's wife that the bathroom needed renovations was easy. She only ever used the upstairs bathroom so she wasn't going to be inconvenienced, and the costs were negligible because Peter would be doing the work as part of his rental agreement.
The cabinet next to the toilet was in rather sad condition, and thus the primary focus of the renovation. A section of the floor under the cabinet was removed, leaving sufficient space for Peter's shoulders to fit through from below, and a nice new custom cabinet was constructed over top of it, with big cupboard doors. Whenever Hal would require Peter's mouth, a rope ladder allowed Peter to climb up from the basement, lift the trap door, and insert his upper body into the cabinet. When the cupboard doors were opened, Peter's mouth would be there, located at a perfectly convenient height for Hal's cock to use.
The renovation was completed over Christmas, and was a complete success as far as Hal was concerned. The quiet tinkle of a servant's bell in the basement was now used to summon Peter whenever Hal wished to pee or get his cock sucked. Peter found himself constantly listening for the bell. Once summoned, waiting in the dark of the cupboard to be used by Hal made him feel more and more like a slave, somewhat of a cross between a sex toy and a urinal. He said as much to Hal, who simply shrugged and asked how his finances were. When Peter admitted they were no better than before, Hal promptly purchased a funnel, and insisted that Peter have the funnel ready in his mouth when he was summoned with one bell, and have his mouth available and prepared to suck when he heard the bell twice. For some reason, having his mouth being filled with urine via a funnel rendered his situation even more objectifying and humiliating.
Peter was now consuming all of Hal's pee, day in, and day out. Morning piss was the worst, but swallowing Hal's cold bottled pee after work was a close second. He sucked Hal's cock and swallowed his cum most mornings and evenings, and yet it still wasn't enough for Hal, who suddenly decreed that Peter would be required to wear a chastity belt whenever he was at home, and be naked while serving him in the cupboard. The chastity belt had been fitted with remote shocking capability, so as well as being summoned by the bell he would sometimes be encouraged to hurry into position by the sharp jolts of pain flowing through his cock and balls. Sometimes, when Hal was feeling particularly cruel, he made sure that the shocks intensified while Peter was sucking his cock. They would peak when Hal orgasmed, and then remain at an almost intolerable level until his whimpering caused Hal to finally take pity on him.
