Chapter Text
“Dude your dog’s balls are huge.” Scott commented one afternoon when the two of them were watching a movie together, a bowl of popcorn sat in the middle of them on the sofa while Stiles’ terrier, Russell, was grooming himself. He was sitting on the middle of the carpet with his tiny leg in the air, lapping away at his furry cock and balls like nobody’s business. Stiles knew his dog has massive balls, and a big dick to match, it was partly the reason he and his father had adopted him from the shelter. It was hilarious watching the terrier run around in excitement, the furry sack swaying between his legs and sometimes getting in the way whenever he sat. The rather large endowment didn’t seem to bother Russell and while it was funny for the teenagers to watch his overly sexual dog hump at their legs, it didn’t humor John.
After a couple months of the dog’s continuous leg humping, John Stilinski had enough and was going to take Russell to the vet to get him fixed, but Stiles had held the terrier in his arms, almost protecting the dog from his father. He was quick to come to Russell’s aid. “Dad it’s inhumane! How would you like it if a doctor cut your balls off?”
“If he mates with a bitch and has puppies, then what? Stiles, he’s obviously frustrated. We could help him in the long run.” John had been the victim to many of Russell’s escapades, sending the terrier to his bed in anger. Stiles didn’t know why it was so offensive to him, Scott only laughed when his leg was captured in Russell’s grasp to be used and he was definitely not complaining about Russell being sexual. He and his dog had a secret that only they could keep, it started a couple months after they’d adopted Russell and Stiles found him humping a pillow, it got the teen curious to see if he could get his terrier off and it escalated from there.
“Well, he’s trained and we always keep him on the leash when he’s outside.” Stiles argued back and forth with his father about Russell, here weren’t any bitches around their neighbourhood, but there was a needy slut who loved his dog in all ways possible. He knew he’d won when he pulled out the trump card; his doe eyes and pouty lips, cuddling him dog close so Russell could lick at his cheek. John was a sucker for his son and soon he waved the two of them away and Russell was free to stride around the house once more now that his balls were safe.
His father went to the home office to work on some of the files he brought home, and Stiles was free to play around with his dog. Normally he would wait until John had gone out the house to work, phoning ahead saying he would be coming home late so the teen had plenty of time to plan his night with his doggy lover. But with his father in the house not only did Stiles have an invisible time limit – not knowing when John could walk into his room at any time – and there was another set of ears in the house so Stiles had to be quiet. Still, the teen played along like normal and called Russell up into his room once the coast was clear. The terrier knew as soon as Stiles called for him upstairs that he was in for a treat; it wasn’t usual that he was allowed in their rooms.
Stiles went through his usual routine; pulling his curtains closed so no one could peek in, his trousers and underwear coming off and grabbing the lube from the bedside dresser. He also made sure to shut the door, not wanting his father to suddenly walk in and get the surprise of his life, lifting Russell up onto the bed because the tiny terrier wasn’t big enough to jump up on his own. Relaxing back into his pillows, Stiles slipped a finger in his hole, wetting the way for another digit to be added and stretched, he had to be quick because he knew his dog got impatient after a while and he wouldn’t care if the teen was prepared or not.
Russell sat and watched the show for a short while before he got fed up, licking his sheath when the pink tip of his doggy cock poked out, and padding around Stiles’ legs letting out little huffs. Three fingers were enough to be safe; while Russell’s dick was big in proportion to his body, it wasn’t the size that he could properly be satisfied with. It couldn’t reach him deep inside where he truly craved it. He giggled when the terrier’s small tongue lapped over the tip of his cock, tasting his salty precum. “Oh good boy, look here.”
Stiles spread his legs and guided Russell between his legs where the dog kept licking over his dick, going further down until his cold nose was pressed up against Stiles’ hole, sniffing the strange scent of musk with the chemical tang of lube. He began to lick at his stretched out hole much to Stiles’ pleasure, his hands wandering up his shirt to pinch and play with his nipples. “Oh yeah, such a good boy. Uhn, good doggy.”
He realised after a couple of round with Russell, the dog was a lot more excited with praise for his efforts, barrelling on with confidence knowing he had his owner’s approval. His tongue laved at the twitching hole one last time before he jumped his small body up, attempting to mount his bitch. “That’s it baby, need some help?”
Stiles’ hole was twitching with anticipation, lifting the terrier’s fluffy front legs up to rest on his stomach so the sheath was lined up with the teen’s ass. He was quick to get things going, reaching down once more to grip the dog’s member and jacking him off until those small hips began humping. “Fuck my hand, mm, gonna make your bitch feel so good.”
He kept a loose grip on Russell’s sheath, guiding it to his hole and holding it there so the dog could find his mark. It didn’t take long, the moment that tip poked inside, the terrier began hammering away at his ass. His front paws scraped off Stiles’ stomach and found purchase on the teen’s spread thighs so he could pull himself closer, getting that doggy dick deep into Stiles’ hole. Now that the small dog was humping, Stiles could take his time to enjoy being fully fucked, holding onto the sheets while the feel of Russell’s furry stomach rubbing his leaking cock and the dog’s thickening shaft banged repeated into his sweet spot. “That’s it…! Oh, good boy. Fuck your bitch, f-fuck me.”
He didn’t care that he could hear himself babbling praise to his doggy, he probably should have being that his father was in the house and might hear him, but he was too far gone. He didn’t care, he just loved the feeling of Russell’s cock filling him, and the fact that he was getting depraved pleasure from his dog, made his stomach coil as he got closer to climax. He couldn’t help it, doggy cock just felt so good. “Mm, yeah. Fuck me with that big dick.”
He could feel Russell’s cock starting to fill out in the base and it made his mouth water because god he was going to knot. Tie him like a bitch and make him take his watery dog cum. The knot bumped against his ass with every frantic thrust, this was the part that Stile craved the most. Feeling like a bitch in heat whenever he was stuck to his dog, the terrier’s cum splashing in his ass with nowhere else to go but deeper inside him. He imagined that Russell’s jizz would get him pregnant with little puppies and they would nurse milk from his plumped up nipples while the terrier marked his territory by tying him again. Stiles let out a gasp at the feeling of Russell’s knot popping in and out of his rim, growing more and more until it finally got too big to be pulled out. “Oh god yes, fill me up. Knot my pussy, baby.”
The terrier continued to hunch his hips gently before finally hitting his climax, halting and lolling his tongue out to pant heartily while he dumped his doggy cum in Stiles. The sensation of it spurting rhythmically against his inner walls and the dog’s stomach rubbing the underside of his twitching dick was finally enough to pull Stiles’ orgasm out of his balls, whimpering when his own member jerked and pumped out his own release onto his stomach, running down his skin to finally soak into the sheets below. He didn’t notice, his mind too blissed out from his orgasm and doggy cum in his hole. “Good doggy, knotted your bitch up real good…”
After a moment’s peace, Russell began to pull away from Stiles and attempted to tug his knot free from Stiles’ sensitive rim. The terrier turned around awkwardly, whining when he couldn’t get far but the teen was quick to rest a hand on the furry back, soothing his dog. “Stay, s-stay boy.”
It didn’t normally take long for Russell to pop free, while he was well endowed for a dog his size, he still didn’t have enough to fully keep his cock locked inside for a long period of time. It took a couple of minutes until Russell’s tugging paid off, padding to the other side of the bed to lick at his length while Stiles’ hole leaked watery dog cum onto the sheets. Their fucking was good, he couldn’t complain about that, but something inside him wasn’t fully satisfied, like an itch that needed scratching deep inside that he was unable to achieve with Russell. Maybe he needed a bigger dog?
