Chapter 13: Cum Toilet Dog Sluts

Luna shivered with excitement when the trainers led them out of the building. Today was a bright and sunny Saturday. It would have been the perfect day to spend at the park, frolicking and fucking with Owen. Alas, she was a trainee at the obedience school and today was their first cum toilet assignment.

Cum toilets were a recent idea that had seen limited implementation across the country. Some people thought they were depraved, but others thought that they were a good idea. Having cum toilets was supposed to increase citizen happiness and reduce sexual assault because there were already approved holes for use.

Luna had never seen a cum toilet in person before, and now she was about to become one! She all but bounced in her spot in the back of the pickup as the trainers drove them through the city. All the girls were buck naked, leashed, chained, a sight that drew the attention of all the passers-by.

Soon enough, they came to a public toilet right next to the biggest park.

“C’mon Luna, down girl.” Delbert reached into the back of the pickup and yanked on Luna’s leash. She obediently hopped down and got on her hands and knees.

Delbert leered at her, and slapped her lightly twice before leading her over to the toilet.

There was already a man there, pulling down his pants and about to pee into the urinal, but he stopped when he saw Luna being led in.

There was a special station in the toilet designated for public cumdumps. It was a small tiled area with a hook where Luna’s leash would be attached. There were a variety of toys in several plastic holders affixed to the wall, and a little bidet that people could use to hose off the cumdump when it got too dirty.

“Morning! Would you like to be this cumslut’s first piss today?” Delbert asked the man as he set about securing Luna’s leash to the hook. The leash had just enough give that she could reach the edges of the tiled area, but couldn’t leave.

“Don’t mind if I do!” the man said with a leer on his face.

Delbert slapped Luna again, then stepped back.

“Arf arf!” Luna barked, putting her arms up in the begging position. She opened her mouth as wide as it could go and waited patiently for the man to do his business.

The man grinned, stepped forwards and fed his stiffening cock into Luna’s mouth.

She moaned softly when he released his urine, savouring the pungent odour of male piss. Two years ago, Luna would have never imagined that she would one day be eagerly drinking pee directly from a man’s cock. Yet now, her cunt was dripping, aroused at the humiliation of being used as a urinal by a stranger.

Luna kept eye contact with the man as she gulped down the golden liquid. He groaned as his cock rose to full hardness between Luna’s pink lips.

“Oh yeah, such a good cumdump,” he growled, starting to facefuck Luna.

All the deepthroat training was starting to pay off. The man’s cock slid into Luna’s throat with ease and she swallowed around it, eyes drifting closed as her lips bumped into the wiry bush of hair at the base of his shaft.

His hands found Luna’s pigtails and yanked her forwards, forcing his cock deeper still. In this position, with her nose mashed into his groin, Luna was nothing but a hole meant for serving dick. Her young mind slowly slipped and slid into that submissive state where all that existed was the thick organ currently buried in her throat.

Luna’s eyes fluttered shut for a moment as the joy of submitting to a dominant man suffused her entire body. She loved being in this subservient position, being used like the fucktoy she was. Her body thrummed with arousal

“Oh! Is that the new cumdump?” someone asked as they walked into the toilet.

“Sure is!” Delbert said on his way out. He clapped the newcomer on the shoulder on his way out and grinned. “Have fun with the slut!”

Being referred to in such a degrading way only made Luna’s pussy gush even more. Her eyes rolled up into her head and she moaned around the cock in her mouth.

“Wow, a tagged slut,” the new person said with admiration in his voice. He moved around behind Luna and then smacked her rear once.

Luna wasted no time in raising her ass high into the air. There was a brief sound from a zipper, than a soft grunt of surprise when the man prised apart her asscheeks.

“Check out the asslips on this one!” he commented, scraping his nail across Luna’s puffy rim.

Luna moaned in arousal. Every time someone pointed out her asslips, she felt a wave of humiliation and desire. Yes, she had fucked so hard and roughly that her shithole was starting to turn inside out! And yes, she was such a anal whore that she didn’t have time to let it rest and get to back normal! Her asslips were a surefire sign that Luna was a through and through ass-slut!

The man lined up his cock and slammed it inside Luna without a second thought!

Luna was being fucked from the front AND from the back! Her mind was overcome with how subby she felt! She was being a GOOD cumdump! Her clit tag swung back and forth on her obscenely large and erect clit while the two strangers fucked her orifices roughly.

Her asshole was sore from nonstop rough treatment, but somehow that only made her feel hornier. Her bottom has been rawed by the trainers, and now it was being rawed by strangers. She was serving cocks, as she was meant to!

“Wow, you guys are early!” another man commented as he entered the toilet.

He bypassed the urinals and came to stand in front of the fucking trio.

“Wait! Oh my god, is that Luna Carter?” he exclaimed, whipping out his phone.

“Luna Carter?” the man fucking her ass asked.

“Yeah, she’s one of the top performers on Dogtube, I saw some of her vids and she’s a total whore for her dog!” the newcomer explained like Luna wasn’t even there. It only made her hornier still.

“So her asshole got like this from getting drilled by doggie dick?” the man marveled, pulling back out to admire Luna’s asslips again.

“Yup! Not only that, she’s a certified zoophile. She can’t cum unless she’s got a knot in her asshole!”

Those words made Luna’s face go bright red in embarrassment and pride. He had told nothing but the truth, but it sounded extra obscene when he said it, not like the purehearted mating she had in mind!

The newcomer crouched to take a look at Luna’s swinging clit jewelry and then gave it a tweak with his fingers.

“I read about her lewd clit, but seeing it in person is on a whole different level,” he marveled, “It’s about four times the size of a normal clit and it doesn’t look like it’s about to stop growing!”

“When you say she’s a dogslut, does that mean she’ll cum on my dog’s cock?”

“Most likely!”

Luna whimpered on the cock in her mouth. Their discussion hinted at the possibility of getting a knot in her ass soon. Her classes and lessons in KOKs hadn’t progressed that far yet and she was missing a good thick knot in her shithole!

“Of course she cums on a knot!” said a familiar voice.

Luna’s eyes flew wide open and she pulled back off the dick she was sucking.

There, standing in the doorway of the men’s room, was her human Daddy Michael Stanton and her studsband Owen!

Owen was growling a little, eager to get at his bitchwife that he hadn’t seen for a week! This was probably the first time that he had been denied usage of her holes for so long. Luna felt a little bit guilty for that, but she was doing this to be a better bitch for him in the long run!

“ARF ARF ARF!” Luna barked happily, the sounds coming to her naturally after a week of not using her voice. She was getting more and more accustomed to communicating in barks and yips instead of words now. All in the name of becoming a better knotwhore!

“Now now, Luna. Remember your lessons! Always pay attention to the men who are using you!” Daddy scolded her.

Luna hurriedly put her mouth back onto the stranger’s cock like the good little slave she was.

“Damn, now I want to see her fuck a dog.”

“Yeah me too!”

Almost immediately the men left Luna’s holes, leaving her free to breed. Luna whined, desolate at having her holes vacant. She wanted to serve cock!

“Well, if you don’t mind, Owen has been away from his bitchwife for a little too long!” Daddy said. He unclipped Owen’s leash and the Doberman immediately POUNCED on Luna!

The red rocket that Luna loved so much stabbed at her pussy and ass relentlessly. Luna bent her head to the ground and lifted her ass higher. The next rough thrust slammed Owen’s thick canine cock into her waiting shitter.

“OOOOOOO!” Luna howled like a bitch as her ass was bred!

SHCLORP SHLORP, went her obscene asslips as they sucked on Owen’s shaft and milked the dog for all he was worth.

“That’s fucking incredible!” one of the men exclaimed as Owen drilled Luna’s eager asshole. She shook her hips harder, fucking back onto the cock of the beast that owned her.

It had been only about six months from the day she signed the papers, but now she was a certified dogslut and getting assfucked by her studsband in front of complete strangers in a public space. Filming for DogTube had never felt this exposing or humiliating to Luna! Fortunately though, as a teenwhore, both being exposed and humiliated only caused her cunt to ooze more bitchslick.

“AWOO WOO ARUUUU!” Luna whined when Owen’s cock started to swell.

The familiar stretch of his knot in her well-abused and used shitter was bliss to her knot addicted mind. After a week of only sucking and fucking human dicks, she was craving a good anal knotting!

Luna’s bitchslick was sliding down between her thighs, making her all gooey as Owen made use of what was lawfully and rightfully his.

“Wow, that’s some next level slut!” a new voice commented.

There was a murmur of agreement and then the shutter click sound of photos being taken.

“GRRRR!” Owen growled, pushing his knot fully into Luna’s hole. Luna couldn’t help herself any longer. She whimpered pitifully, her body tensing up as she had her first painalgasm in a week. Her rectal walls pulsed periodically, eager to receive Own’s marital gift of sperm.

“Is she cumming? What a whore!”

“That’s a trueblue knotslut if I ever saw one!”

“Was that a painalgasm?”

The whispers around her grew as more men joined the crowd. Somehow, streaming live on Dogtube and being knotted live in front of such a rapt audience felt so different. Here, Luna could feel the excitement of the men as they tried to get a better look at where Owen’s knot was firmly lodged in Luna’s shitter.

“Man, this slut has got asslips thicker than some girls’ mouths!” someone exclaimed.

Luna moaned, shivering all over at the observation. Her asslips were something she was really proud of, seeing as only constant unrelenting anal could produce such obscene lips! Anyone who saw the size of her puffy rim would instantly know her dedication to anal.

“Arf arf,” she whimpered as another painalgasm surged through her body. Her bitchwife pendant swung on her thick clit, glinting as the men snapped pictures with their phones.

Being on her knees like this, submitting to the brutal humping of her studsband, while being filmed by a bunch of perverted men, it was all so humiliating! But Luna loved it all the more because of that! She loved being degraded, called a knotslut, told that her ass was ruined, because it was all true!

“GRRRR WOOF WOOF!” Owen barked as he staked his claim on his bitch ... Nothing felt better than his mate’s sloppy hole twitching and spasming on his knot! Of course, he didn’t care whether it brought her pleasure or not. His only care was pumping her full of his virile dog semen!

“Luna bitch! Look here!” someone shouted.

Luna turned her head in the direction of the sound. There was a flash and click of a camera.

Ah, her misdeeds and perverse canine predilections would live on in the phones and galleries of so many strange men. It was all she could have hoped for and more!

Luna was truly cock-addled, knot mad from how much she wanted and desired to be bred by her studsband! She shook her hips faster, humping herself back and forth on Owen’s knot, whining and whimpering like the eager bitch she was!

Having gone so long without mating his bitchwife, Owen was pent up. His low hanging balls swung heavy with days of unreleased sperm, slapping against his mate’s empty pussy. Each time they hit her folds, there would be a wet splat, the sound of copious amounts of bitchslick! Truly, nothing pleased Owen more than his sweet little bitchwife. She was always so eager to take his knot, always dripping with slick that let Owen know she was a submissive canine slut. This time, he wouldn’t release her until she was full of his puppies. He would breed her over and over and over again until her holes overflowed with his puppy batter!

“How long does this usually take?” Someone asked, a sense of wonder in their voice.

“At least 45 minutes,” Luna’s Daddy replied with relish, “But seeing as Owen has fucked his bitch for a week, I expect today’s session to go on for an extra half hour or longer!”

Being locked together for an hour sounded like heaven to Luna, so much so that the idea of it sent her into YET another painalgasm! Her hole twitched and spasmed repeatedly, her young body shivering and shaking as she relished the thought of serving her studsband’s meaty canine rocket for that long! The pain and agony of having her shithole stretched would be made all the sweeter with the weight of her mate on her back, his doggy dick blasting her insides with his semen, and dozens of men jerking their cocks at the perverse scene!

“GRRRR WOOF WOOF GRRR!” Owen barked and growled as he began to unload a week’s worth of jizz into Luna’s sore orifice.

Luna’s eyes rolled up into her head as she experienced yet another powerful painalgasm, made all the more better by a live audience who cheered on each of her lewd expressions and undertakings.

She shivered, spasmed, and shook apart under her dominant canine husband, unable to do anything but moan as he bred her relentlessly. Blast after blast of doggie jizz surged into her bowels, filling her rectal cavity with scorching animal cum!

“AOO OOOO ARF ARF!” Luna barked in slutty ecstasy, her body quivering with pleasure the way only a knotwhore could when assfucked viciously with a knot!

“Yeah! Breed that bitch!”

“Oh my god I’m gonna go get my Rover!”

“What a fucking knotslut!”

“Look up, Luna!” someone shouted. Luna turned her head and immediately received a blast of cum to her face. Ropes of thick ropey semen splashed across her nose, cheeks, and mouth. Her lips parted automatically, tongue coming out to receive the precious gift!

The watching men cheered, stroking their cocks furiously as they watched a young 18 year old blonde being railed by her canine mate. The fact that this young woman was not only willingly letting a dog fuck her in the ass in such a vicious manner, but she was moaning, shaking her hips eagerly and cumming repeatedly from painful anal pounding, was a scene that not many of the men had a chance to see in the flesh! They cheered her on, shouting demeaning phrases to encourage her slutty behaviour!

In the back, Michael Stanton stood with a wide grin on his face. Luna’s knot addiction was only increasing day by day. She would pass off today’s non-stop painalgasms as due to having not seen Owen in a while, but Michael knew that it was because he had been mashing the ‘Cum’ button over and over again. She probably would have managed a few on her own, but Michael didn’t want to leave anything to chance. If she ever started to doubt whether she truly enjoyed canine cock, or if she one day wanted to deny her fondness for painal, well, there would be dozens of videos of her cumming on Owen’s knot on her first day of being a cum toilet!

Owen, finally satisfied with staking his claim on Luna, dismounted. His deflating knot tugged the rim of Luna’s asshole outwards, turning it inside out with a loud pop. The pink insides of Luna’s shitter blossomed outwards like an obscene rose and the poor abused slut whimpered in pain.

“Oh fuck! Her ass is inside out!” someone exclaimed.

Michael walked over to the rack of toys and pulled out a cane. He gave it a few experimental swishes and then swung it down hard, landing it right on top of Luna’s prolapsed anus!

“ARF ARF ARF!” Luna yipped in agony as her rosebud was caned roughly. Painful looking red welts crisscrossed her pale asscheeks and the pink bud of her inside-out shitter, but she was helpless to stop the violent anal punishment.

Globs of dog semen oozed out as Michael rained down blows onto the inverted pucker. Luna sobbed and whimpered, but made no attempt to move away from the violent treatment. Her utter submission and acceptance of her place was making all of the men there extremely hard.

“Is that what they’re teaching you at the school? Letting go of all those precious gifts?” Michael demanded.

Sniffling, Luna turned around and began to lap up the cum that had splattered on the floor.

Watching a young girl obediently lick cum off a toilet floor after cumming her brains out, her ass high in the air and exposing her prolapsed shitter that had been caused by rough anal knotting, while her giant clit and its tag shone brightly under her sopping wet cunt, it was easily the most depraved and perverse things that her audience had ever seen.

“I think she might need help getting that asshole put back in!” someone said. The click of claws on the tiled toilet floor made the crowd part.

Luna raised her head in question as Michael pulled Owen out of the way.

One of the men had brought in a mutt. It was obviously a stray, a little unkempt and shaggy, but it had smelt Luna’s bitch scent and it was ready to start breeding!
