Our story takes place in a small country, inhabited by both Red and Giant pandas. Long ago, the Giant Panda population declined to a point of near extinction. In a desperate attempt to save their race, they submitted themselves to the Red Pandas, known as the Wahs. 
The Wahs instituted a mass breeding program, and outlawed homosexuality among the Giant Pandas. Given the level of control the Wahs possessed over the Giant Pandas, it wasn't long before they had reduced the Giant Pandas to little more than slaves, using them for manual labor and many other degrading things. This has been going on for so long now, that no Giant Panda can recall a time when they did not serve the Wahs.
Our tale is focused upon a Giant Panda by the name of Boliver. After he was determined to be too weak for manual labor, he was assigned to the breeding program, and ordered to mate with a female panda. When the time came to carry out his duty, Boliver found himself unable to sustain an erection, as he had no sexual interest in the female. Upon realizing Boliver's shortcomings, the female taunted and teased him, and he was taken away to the Punishment Dungeon....

The sound of Boliver's yelps and squeals echoed throughout the dungeon as his Wah torturer beats Boliver's backside with a wooden paddle, while simultaneously berating him and calling him all manner of demeaning, vulgar names. This continues for a while, until finally Boliver is flipped over, and his cock is stuffed into a small, tight, chastity cage, which is promptly locked. 
He is strapped in place, and ordered not to look away, as another giant panda is led into the room. The second panda is forced to sit down in a chair with a large butt-plug covered with small metal bumps in the center of it's seat, with chains and shackles located above and below it. As soon as he is seated and restrained with his arms above his head, a faint buzzing, and occasional zapping, noise can be heard from the chair, causing the panda to squirm and whimper as his member quickly stiffens, rising to full attention while throbbing needily between his legs.
A thick, dirty rope is looped around the restrained panda's neck, before the guard who brought him in turns on the device attached to the back of the chair, causing the rope to start drawing tighter and tighter. The panda quickly begins thrashing and pulling against his bonds, trying to break free so that he can stop the garrote from sealing off his airway. Desperate gagging sounds escape his mouth as his tongue is forced out past his lips. Before too much longer, the bound panda's member twitches, spraying ropes of panda cum over his stomach, before going limp.
Following the other panda's execution, Boliver is delivered into an isolation cell, where he is left alone for a month. During which, his mind frequently wandered back to the death of the other panda. These thoughts cause Boliver's cock to strain in its tight cage, and lead to him fingering himself while tugging at his cage, in an attempt to get off. On the day he was to be released from the cell and returned to the breeding program, the guards happened to catch Boliver fingering himself. In response, they dragged him out of the cell, took him back to the punishment dungeon, removed his cage, and shackled him directly to the wall, leaving him in a quite uncomfortable position, and unable to relieve himself in any way.
He has been informed that his punishment is going to be carried out by a Wah who specializes in dealing with inferior giant pandas, and across from him he can see the very device that was used to snuff out the life of another panda one month ago.
As his torturer enters the room, he slaps Boliver in the face with his tail. With a smirk, he looks up at the larger animal. "Pathetic. Your type doesn't even have a real tail... Can you get anything right?" He taunts, rubbing his fluffy tail across Boliver's face again. "I suppose a worthless reject like you doesn't deserve any better, though."
Scoffing at him, the red panda walks over to a pot filled with burning hot coals, with a short metal brand sticking out of it. He takes the brand by the handle, and brings it over to Boliver, who starts to squirm at the sight of the tool, begging the Wah not to use it on him. "Tsk tsk, now now. How will anyone recognize you as the faggot you are, if I don't mark you properly?" Without saying another word, the Wah presses the burning head of the brand to Boliver's thigh, searing the words "Broken Panda" into his flesh and causing Boliver to howl in agony.
Tossing the brand aside, the red panda slams his fist into Boliver's balls, smacking them against the stone wall behind him and causing the already pained panda to cry out again. Smirking sadistically, the red panda proceeds to punch, kick, and squeeze his unfortunate victim's testes, quickly causing them to swell up and begin to bruise. Noticing this, the torturer grins and unlocks Boliver's bonds, causing him to groan and whine as he drops to the floor. Not giving him any time to recover, his torturer drags him over to a table with a set of shackles attached to it, forces him to lay down on it on his back, and locks him in place.
The torturer quickly climbs up onto Boliver's chest, and sticks both of his feet in his face. "Start licking, you worthless slut." He commands, rubbing both of his feet on the panda's cheeks. Boliver whimpers, before screwing his eyes shut and complying, dragging his tongue all over the Wah's fuzzy feet, running it in between his toes and across his arches. "Heheh... That's enough!" He snaps, kicking Boliver in the face and climbing off of him. 
Stripping out of his pants, the torturer starts to rub his raging erection against Boliver's cheek. "You know what to do, you worthless slut." Boliver whimpers, then starts obediently sucking on the Wah's thick member, sliding his tongue under the hood of his tormentor's foreskin, prompting a satisfied noise from him. Boliver slurps and suckles on the Wah's throbbing length, pre-cum dribbling from his own tip as the red panda reaches back, taking ahold of Boliver's member, and begins to rub it. As Boliver sucks, his torturer starts to rapidly jack his throbbing, desperate, member, eliciting squeaky moans from the bound panda. Within moments, Boliver is lustily thrusting upwards, trying to get that last little push he needs to reach climax, only for the Wah to release his member, cruelly denying him his release. Laughing at Boliver's frustrated, needy whines, the Wah starts thrusting roughly into Boliver's mouth, face-fucking him for a few moments, before letting out a pleased sigh as he begins to spurt a copious load down his victim's throat, forcing Boliver to swallow as quickly as he can.
"Mmn... Not bad, for a slutty faggot panda. Course, I'm not done with you yet..." The Wah says, gripping Boliver's head and holding it in place. The sound of flowing liquid can be heard, and Boliver begins to thrash and squirm, as the Wah begins to piss straight down the panda's throat, causing him to choke and gag on the bitter liquid. Tears start to roll down his cheeks, as the stream of hot urine starts to die down and the wah pulls out, holding Boliver's mouth shut as he finishes up on his face. "Swallow!" Screwing his eyes shut, Boliver swallows whats left of the Wah's piss in his mouth, then begins gasping and gagging once his muzzle is released.
Untying Boliver and leading the dazed Panda over to the seated device, the Wah forces him down onto the lubricated pole in the center of the seat, then binds him in place. He then throws a switch, causing the pole to begin vibrating and zapping Boliver's prostate, eliciting yelps and moans from him. Smirking to himself, he wraps the garrote around Boliver's neck and turns on the machine, quickly causing him to start choking and gagging, thrashing desperately in his seat as his member throbs. The Wah steps back and grins, crossing his arms as Boliver finally hits his climax, spraying jet after jet of sticky panda cum onto his stomach, as everything begins to fade into a peaceful black darkness...

Boliver awakens bound on his back to some kind of table, his Wah executioner standing over him and grinning. "Good to see you're awake. Oh, you didn't think a filthy broken panda like you deserved to die just once, did you? No no, thats far too good for you..." He says, taking ahold of Boliver's orbs. "No, we're going to have a LOT of fun, you and I. Doing things such as this, over, and over, and OVER!" The Wah shouts, punctuating his statement by squeezing one of Boliver's balls harder and harder, until it collapses into mush with a loud pop, causing Boliver to scream. Boliver stares at the ceiling, knowing he is in for a very special kind of hell in the days to come.
