Master Francesco inserted a funnel gag into its mouth, strapping it around the head. He bound the arms behind the back in leather cuffs shackled together with an S clip, separated and secured the legs with a spreader bar attached above the knees, locked the neck in a thick steel collar and then connected that with a short steel linked chain clipped to an iron ring on the floor so it couldn't escape from a prone position. He allowed it to kneel on a cushion, although he could just as easily have made it kneel on the floor without protection for its knees, but today he was feeling mildly compassionate. Every dog deserved some comfort; and it was going to be there a while.
The first thing he poured into the funnel was a glass of cold water, giving it time to swallow. Master Francesco patted its head, and then went about his business with some paper work on the table by the window. He screwed open a bottle of beer. Twenty minutes later he poured down another glass of water, a larger one, and he heard the gulping sound in the throat. This went on for an hour or so: fussing with paper work, chugging back beer, a phone call now and then, and finally a mumbled conversation with his buddy Jamal that ended "Okay, if that's what you want, bro, see you there." He then turned his attention to the shackled beast on the floor. Sometimes he spit into the funnel and washed it down with his beer.
After two hours, Karl squirmed in the restraints, his knees aching even on the pillows, needing to relieve himself, but of course could not and would not without permission. He wasn't unhappy; in fact, he had discovered some satisfaction in being restrained, the freedom of movement taken away for a specific period of time, the chaining an integral and natural part of his submission to Master Francesco. As physical discomfort increased, however, he twitched with anxiety, maybe even incipient panic. Swallowing became painful as water or beer poured down his throat as he struggled to prevent choking and sputtering. An instinctive resistance still mulling about his bones and cells and DNA, a human resistance, he understood, that had to be altered and ultimately eliminated. No, he wasn't comfortable but even thinking of his own comfort constituted a violation of sorts, a violation against Master Francesco's will and whim, a subtle challenge against the Master's wishes.
As he watched Master Francesco fidget on the seat, ruffling papers, putting out half-smoked cigarettes and lighting another, his caged cock strained against its restraint. He followed the outlines of the young Master's muscles. Dedicated bodybuilding had created a body that made cunts and fags cum in their pants, except he was not allowed to cum anywhere unless Master Francesco allowed it, not even when the former student, now his Master, rammed his student cock into and fucked the professor over his office desk, or fucked him hard in his car, and his entire body blazed in frustration and heat and brought him to the edge over and over and over. He realized with an animal passion that he needed to be whatever his master, Francesco the former student, wanted him to be.
Karl thought he gurgled a mild protest, but the funnel gag kept it lodged in his throat. Then Master Francesco towered stood over him, unzipped his jeans, pulled out his semi-erect and tantalizing cock, and pissed slowly and steadily into the funnel, allowing Karl to gulp it down. When the steaming yellow liquid welled up in his mouth, Karl coughed and sputtered. Master Francesco smacked the side of the dog's head with a rolled-up newspaper, and finished pissing. He followed that with more water, the dog swallowing as fast as it could, its belly beginning to swell. Despite the water mixed with Master Francesco's piss gurgling back up into the funnel, it did not overflow this time and Karl was pleased, a pleasure mingled with ripples of fear, that he had achieved the task of consuming all the liquid. Karl could feel his kidneys practically working overtime and his bladder was beginning to ache.
Three hours passed and Karl's entire focus was directed towards his bladder, how to control himself. Master Francesco grabbed his arms and with his assistance, Karl was relieved to be allowed to stand, the collar freed from the floor ring, his blood flowing through his legs, still constrained by the spreader bar. His arms kept shackled behind its back, it began shaking in a kind of constrained piss dance which made Master Francesco laugh out loud before smacking it across the head again with the newspaper roll. Then he smacked the other side for good measure, and the dog heard the anger in the master's voice. It yelped inside its skull, but nothing Master Francesco could hear. Despite the blow, which it knew it deserved, it looked with fond eyes upon Master Francesco, hoping his former student would see both desperation and love, and show mercy.
"Get used to it, fuckpig. It pisses when I give it permission to piss." Master Francesco unlocked the spreader bar and forced it on its knees again, and led it to the dog cage in the bedroom, a cage large enough to hold a German shepherd. Master Francesco removed the funnel gag long, kicked Karl's ass while it crawled and wedged itself within the bars, locked the door, then reinserted the gag in the animal's mouth from outside the cage, the funnel extending between the bars. And he poured another quantity of water down its throat.
If it didn't try to move, the pressure on its bladder would ease. His mind ranged wildly between animal and human. At one time, he was the master's German history professor in college, and the master was a hulking muscle jock student with an attitude, who sat in the front row, legs spread, hand dangling over his crotch, knowing the professor couldn't help sneaking looks at the bulge between the strong legs. He knew that the student saw him. And it all began when Francesco came to his office for help with an essay. How long ago? About a year had passed. He couldn't help but kneel before his student and beg to be used, to be owned by young muscle, knowing that Francesco, older than the average student, whose cock had fucked submissive cunts and fags in dark and exhilarating forms of domination.
The temptation to piss in the cage was enormous. It knew that of all things pissing in the cage would have been a serious offence against its lord and Master: "You piss in the cage, bitch, I'll string you up and flog your ass till it turns purple. You won't be a dog bitch then, but a screaming piece of subhuman shit begging for mercy. You got that?"
A hateful idea, it knew Master meant what he said since it had been flogged several times to the point of excruciating and ecstatic pain, so it tried to remain still, its stomach distending, its bladder screaming. Master returned to the room and pissed again into the funnel. The sensation of the piss, hot and acrid gushing into the mouth and down its throat almost made the dog want to vomit, but it controlled itself and obediently swallowed, its throat working instinctively. To his credit, Master controlled the flow so that the dog was able to gulp it down readily enough without spilling it out. That was immediately followed by more beer, the taste almost indistinguishable from Master's piss. Master removed the funnel gag, and opened the cage door and helped the creature stand. He unlocked the spreader bar and freed the arms, and removed the gag.
"Don't you dare piss, bitch. Get dressed."
Slowly, as if remembering or trying to remember how a human being dressed itself, it obeyed, each movement painful and risky, lifting a leg or lifting an arm mechanically as if in imitation of something it had seen, but slowly, nervously, because it could hardly refrain from pissing, and was terrified of even so much as a dribble or leaking cock. When it bent over to put on its pants, liquid surged up to its throat and pressure on its bladder almost making it burst, it forced itself to plead.
"Please, please Master Francesco, please, please, please let your bitch relieve itself, it needs to piss so badly." Its words sounded human, real words, neither growls nor barks. Master Francesco smacked its head with the roll of paper. "Shut the fuck up. Did I say you could speak?"
It could hardly walk, its eyes tearing up. Like that irreversible moment when ejaculation begins and can't be stopped, the moment would come when the dog wouldn't be able to stop itself from pissing, and would have to face the consequences. Master Francesco led the animal through the empty corridor to the elevator, which they took down to the lobby. Karl's car was parked on the road in front of the apartment building. Master Francesco got behind the driver's seat and the dog, struggling in pain and unbearable tension, crawled into the passenger side.
"You want to piss, bitch? Speak."
"Yes, Master, please, yes, fuck, it hurts."
