"Tying the knot" by nuthouse The doberman got a pat down with a warm towel to dry off the remaining water from his scrub. His coat was a sleek, shiny black, and had been combed smooth. His teeth were brushed, his whiskers trimmed, his nether regions washed, his nails clipped. No part had been left unattended. The two orbs dangling between his rear legs were rinsed with warm water to ensure that their details were visible. He was motioned to the breeding rack, and he obliged, gingerly walking over with his back legs spread wide. He placed his torso in the belly of the rack's grip and felt the strap being wrapped tightly around his back. He had been prepped prior to the show so that his testicles were already drawn out of his scrotum. This had ostensibly been done to avoid unnecessary lacerations during the show. But it was also done to instill commitment and avoid any last-minute changes of heart. The seedier side of the internet was willing to shell out large amounts of cash for this sort of scene, and if anything were cut short besides testicles, there would be money lost. After being strapped into the breeding rack, he felt fingers adjusting his male parts. They were gentle, as if recognizing the tenderness of their work. His left testicle was softly tugged until it dangled at the same level as his right. He was told that the webcam audience and his stud would love seeing such a finely-developed set. He had heard two things about the stud: that he was well-endowed, and that he loved fit, clean specimens. The doberman's trim, powerful body was sure to appeal. Next, his sheath was pulled back and his penis was bathed with warm water. He was jerked until he started to swell, at which point a rope was tied behind his thickening knot. The tightness caused him to harden further. His sheath was released but he remained exposed due to the rope, which had him forcibly erect and dribbling. A generous amount of lubricant was applied to his tailhole and rubbed inside his musky opening to help ready him for anal penetration. The lubed finger went in deep and rubbed at his prostate, causing him to squirm. Last came a wire-frame muzzle that was strapped around the back of his neck. "Are you ready?" The doberman nodded, and was rewarded with a pat on the head. The webcams were turned on, and the whir of electronics filled the alleyway. Red lights indicated that he was live. The doberman felt a momentary pang of self-consciousness at his exposure. But the feeling was short-lived, as the sound of a metal gate squealing open quickly diverted his attention. Heavy pawsteps came from down the alleyway. They loudened until stopping behind him. The doberman looked back and saw their imposing owner: a huge, steel-gray bandog with tightly cropped ears and a white blotch on his chest. The doberman turned back his ears to fake alarm. The bandog circled the doberman, eyeing up his body. He investigated legs and torso for muscle mass. He ran his muzzle down the doberman's taut underside, prodding with his nose to check for fat. Arriving at his abdomen, he grunted in approval at finding none. The doberman could feel the bandog's hot breath on his penis, which twitched in arousal at his vulnerability. The bandog nuzzled it with his nose, sniffing greedily. The doberman felt himself engulfed in a wet, warm tongue. Several licks focused on his sensitive tip, and the bandog was rewarded with thick spurts of dobie cum. The bandog continued around, appraising the doberman's body as if he were a slab of meat, and occasionally prodding at an area with his nose. As the bandog circled, the doberman noticed an imposing sheath, thicker than any he had seen, flopping heavily between his legs. A pink tip poked out, and the slight outline of a developing knot was visible in his sheath. Regardless of how prepared the doberman was, that powerful breeding tool was going to hurt. His tailhole clenched instinctively. The bandog returned to the doberman's rear, and the doberman felt hot breath on his dangling orbs as they were examined for size and consistency. The doberman knew from experience that his boys were quite healthy, producing more raging hormones and sperm than he knew what to do with. The stud took the exposed testicles in his mouth, massaging them between his rough tongue and the ridged roof of his mouth. The doberman wondered if it was time for that already. The answer was no, as the bandog released them from his maw. The testicles shimmered with his warm, sticky drool, which dribbled to the ground. The dobie pretended to struggle in the breeding rack, waving his ass as best he could in front of the bandog. This had the desired effect, as the doberman felt a sudden weight on his back, and powerful legs gripped the sides of his body as claws dug into him. The pointy member made several painful jabs at his backside before hitting home and fucking the dobie's warm hole. It slipped rapidly in and out as the bandog thrust at him in a frenzy. The dobie's testicles bounced from their cords as he was humped. Finally, the bandog sank his knot, and the dobie's tailhole locked him in, causing the knot to inflate in synchronization with the bandog's pulse. The knot was soon rubbing against the doberman's prostate as it grew to a pleasurable size and far beyond. As the tie crossed the threshold from pleasure to pain, he began to panic as he realized the bandog was too big for him. The doberman tried not to grimace as the bandog's massive tool knotted inside him and stretched his insides to their limit of pain, the now-short thrusts causing waves of agony and pleasure to ripple throughout his body. No reason to give the webcam viewers even more satisfaction, he thought. It'll be over soon enough. At last, the bandog stopped thrusting and went limp. His hefty weight sagged against the doberman's back, and he emitted grunts in synchronization with his orgasm. The doberman felt his abdomen being pressed hard against the breeding rack from all the weight. His body having done its part to get him a tie, the bandog apparently intended to set his genitals on autopilot and enjoy the ride. The bandog's panting slowed and he sighed. Warm strings of drool rolled from his rank mouth down the doberman's sleek, manicured body. The bandog continued to make small grunting noises, wave after wave of ejaculate plastering the doberman's insides. The doberman could feel the tickle of the warm cum splatter inside him with every shot. In his relaxed state, the bandog farted, unintentionally mocking the doberman's own tightly-plugged hole. They stood tied for a long time. Though still hard, the bandog eventually decided that he was done. He began to pull against the tie that bound them, causing a strong, painful pressure in the doberman's rear. The pressure continued to grow in pain and discomfort until, in a flash of brief but shocking pain, the bandog's knot popped out. The doberman yelped in pain as his tailhole was stretched beyond its limit. His anus gaped as semen poured out. Now that the bandog was freed from the tie, the doberman became painfully aware of his vulnerable testicles hanging by nothing but their cords. It was going to happen sooner or later, but-- SNAP! The bandog chomped down on the cord above his right testicle The doberman blinked in a moment of disbelief. He looked back and saw that it was true: his severed testicle, treasured jewel of many years, dangled from the bandog's grinning maw. The stud dropped it without ceremony, and it splashed in the middle of a sloppy puddle of semen that had just been in the doberman's ass. The bandog took the other ball in his mouth. Despite knowing what he had signed up for, the doberman's mind was reeling with how easily he had lost his first testicle. The doberman shook nervously, expecting this to be the final moment of his castration. He tried to brace himself as best he could, reinforcing his nerves with thoughts of the neutered life that he desired. The bandog nibbled on the cord with his pointy teeth, watching the doberman's tailhole clench in response. The doberman gulped as the bandog rolled the ball around in his mouth, contemplating how easy it would be to press his canines into its spongy body. But to the doberman's surprise, the bandog released the ball and it swung back between his legs, still intact for the moment. The doberman was torn between relief and regret, glad to keep his ball for a little longer, but wanting to get it over with. Going for a different target, the bandog stuck his giant head between the doberman's legs and gripped the rope. With a steady tug, the bandog pulled the doberman's penis between his back legs. The rope had kept him exposed for a long time now, and he was drying out, causing extra sensitivity. The bandog held the rope tight in his mouth so that the audience could get a good look at what the doberman was packing. Then, to the doberman's surprise, the bandog began to pull...
