Sirius took his pocket mirror out of his jacket, just to check his hair one more time. It was perfectly unperfect, as always. Just like he wanted it to be. There was no way this Moony guy would be disappointed once he opened his door and noticed his Tinder date was even better looking in real life than in the pictures. He could only hope that this Moony guy was equally as honest. He seemed like a handsome young man, although he didn’t put his age up, but seemed to be somewhere around Sirius’. All of his pictures were with a big, almost wolf-like grey dog, and he even made a little joke in his profile description, saying “I’m just a big dog, looking for a mate”, making Sirius laugh and swipe right on him.
In their conversation, Moony was a pretty straight forward guy, not being much for meaningless chit chats, going exactly for what he wanted and asking Sirius if they could meet up at his place.
“To have sex,” he specified, although Sirius thought that was implied. It was not like he was coming over to have dinner and watch a movie. With this guy, he didn’t have to pretend to enjoy his conversations before he would get to the real deal. In all honesty, Sirius was horny as fuck, not getting it months and it was about time for him to get some action.
It did get a bit weird at one point when Moony talked about himself in third person, telling him that “Moony can’t wait to meet you”, but he was hot enough for Sirius to disregard that. So what if he was a bit kooky, who wasn’t nowadays?
He took a deep breath, knocking on the apartment door. Just in case, he informed James about his location, if it turned out that Moony was in fact not just a little bit kooky but a full-blown serial killer who used Tinder to lure his victims out.
“Hey there, Sirius,” the same man that Sirius saw on the pictures posted on the app opened the door, instantly relieved that it wasn’t some kind of a fake profile.
“Hey,” he sighed out, smiling.
“I’m Remus, you can come in,” the man said, stepping aside so that Sirius can enter.
“Remus?” Sirius looked at him suspiciously. So, while his pictures might have been real, his name was apparently not.
“Yeah,” he nodded. “We’ve been expecting you.”
“We?!” Sirius froze, his breath hitched.
“Oh, me and Moony, of course,” he laughed as that same big dog from the pictures appeared next to him, looking at Sirius suspiciously.
“Oh, that’s Moony… right,” he laughed, once again relieved. “Hey there, boy!” He looked down at the hound, wondering just what kind of a breed it was, or if it was a dog at all. It sure seemed more like a wolf than a dog.
Moony sniffed his hand letting out a small whimper and looking up at Remus.
“I know,” Remus talked to the dog, nodding. “I think so too.”
Sirius laughed, thinking their bond was simply adorable.
“What kind of a dog is it?” Sirius asked, wondering.
“He’s a wolfdog. Has genes of both German shepherd and of grey wolf.”
Sirius made a grimace. So, he was correct, this was a wolf. Well, almost a wolf.
“I wasn’t even aware you’re allowed to use those as pets.”
Remus frowned. “I don’t really look at him as a pet.”
Sirius nodded. So, Remus was apparently one of those ‘dog is family’ kind of people. Which was perfectly fine, but he didn’t have to look that offended. It was an honest mistake.
“Sorry,” he said. “Of course he’s not just a pet.”
“He’s like an extended version of me,” Remus explained.
Sirius nodded, perfectly understanding. His friend Peter was the same with his pet rat back in school, taking him everywhere with him and letting him sleep in his bed. Sirius could never, but hey… To each their own.
“Come on, the bedroom’s ready,” Remus said, waving for Sirius to follow him, while Moony walked next to him, his tail wagging happily.
“Um… shouldn’t it be better if Moony stayed here?” He asked, but Remus just laughed, telling Moony what a jokester Sirius was.
Once he opened the bedroom door and clicked on the light switch, Sirius was even more confused. There was no proper bed in the bedroom, just a weird mattress pushed into a corner and a chair facing it. That was it from the room decoration, apart from the huge ceiling to floor curtains keeping the daylight away.
“This… is your room?” Sirius asked, confused.
“No, this is Moony’s room. I thought it would be more comfortable here.”
Sirius frowned. Did this mean that the giant dog slept on the bed? He wasn’t exactly looking forward to doing it on the dog’s bed.
“Come on, I’ll help you get ready,” Remus walked over to the chair and took a bottle of some kind of a lotion that was on it.
Sirius thought this was weirdly straightforward, no kissing, no foreplay, just going at it. He shook his head and took his jacket off. Now that he was already here, he might as well do it, there was no need to get into his head about it. The guy was a bit socially inept, but he was also very hot and Sirius did just spend 45 minutes on a bus to get here, so he might as well stay and have some fun.
“I want you on your hands and knees, over there,” Remus pointed at the mattress. “Naked!”
Sirius smirked. There was something oddly fascinating about how commandeering and deep his voice sounded. It made Sirius twitch in his trousers immediately. He rushed to get himself rid of his shirt, kicking his shoes away. It was then that he noticed Moony looming in the doorway, watching him. He thought about asking Remus to close the door, not sure how he felt about being watched, even if it was by a dog.
“Don’t mind him,” Remus said. “He knows how to behave, he’ll be a very good boy.”
“Oh…” Sirius scoffed. “Ok…” He sighed, pulling his trousers down. He was wearing no underwear, the realization causing Remus to smirk.
“You’re a naughty one, aren’t you?” He asked, licking his lips.
Sirius shrugged. “I guess I am, a little bit.”
“I knew that as soon as I saw your profile. I knew you were going to be a good one.”
Sirius leaned down to take his socks off, but was interrupted by Remus. “Leave those.”
“Are you sure? This seems a bit weird,” Sirius chuckled, looking down at his red socks, the rest of him completely naked.
“I have this… um, kind of a fear, a phobia,” Remus explained. “Feet really gross me out.”
“Oh?” Sirius looked at him, puzzled. “I’ll leave them on, then.” He shrugged.
“Thanks,” Remus smiled, spreading the lotion between his hands, coating his fingers with it.
Sirius had to admit, he was kind of turned on by the fact that he was completely naked (apart from the socks) and Remus was still wearing all his clothes. More clothes than necessary, in fact, seeing he was wearing a shirt and a vest over it, probably even a t-shirt underneath them, as he simply looked the type that would.
Remus took a step closer to him, nudging with his head towards the mattress. Sirius took a deep breath as he kneeled down on it, surprised how clean it actually was, considering a dog had slept on it. He positioned himself on all fours, turning around to see Remus as he slowly kneeled behind him.
His cold, sticky hand pushed Sirius’ back further down, making his chest touch the mattress and his back arch, his arse sticking up. He could then feel those same hands on his cheeks, spreading him open. He whined out from the sensation, pushing his hips back.
“What a nice little hole,” Remus chuckled, circling around it with his finger.
Sirius bit his lip, anticipating the breach as Remus was caressing his rim, prolonging it.
“Take a look, Moony,” Remus said, and it was then that Sirius realized the dog was sitting next to Remus. “Look at this desperate little thing twitching.”
“Um… Remus?” Sirius asked, his arsehole immediately clenching up in panic. “Why is Moony here?”
“Oh, you right,” Remus chuckled. “Moony, go away, you’re making Sirius nervous.”
Sirius made a weird grimace. He’d prefer not to have the dog here at all, than to lurk in the doorway like some kind of a voyeur.
“He gets overly excited sometimes. We have to train how to be patient.”
Sirius sighed out, thinking this was probably not all dog’s fault. Remus was lucky Sirius was currently so desperate for his fingers that he was ready to turn a blind eye on this huge red flag. One that would normally get him up and running.
“Yeah, whatever, let’s just get on with it,” he breathed out, his hole relaxing.
Remus finally proceeded, pushing a slippery finger inside of him, making him moan out with relief.
“Yeah, you like that, huh?” Remus chuckled, pulling the finger out, just to push it back inside.
“Yes!” Sirius nodded, desperately nudging his hips back, chasing the feeling.
“Do you want more?”
“Yes! Yes! More!” Sirius panted out, closing his eyes, as he felt Remus adding another one.
“I’m only two fingers in and you’re already like this. What will you do when the real thing comes?” Remus laughed, amused at the way Sirius squirmed under his touch, gasping desperately.
“I’ll go crazy…” Sirius groaned out, imagining Remus’ cock instead of his fingers, his long dry spell getting the best of him.
“Yeah, so will I. Can’t wait to see it,” Remus said, curling his fingers. “Do you want more?”
“Yes!” Sirius screamed out, extatically.
Remus pushed the third finger in.
Sirius whined out, feeling his body open up for Remus, his walls breeched by three long fingers, curling themselves inside of him, stabbing themselves inside up to the knuckle, the sound of squelching filling the room up. Somewhere in the distance, Moony barked and Remus turned around to tell the dog something, but none of it mattered, as all that Sirius could hear was his blood swishing through his body, his heart beating in his ears. Yes, this, more of this. He wanted and needed this to last as long as possible, but as soon as those fingers reached his prostate, he knew he was doomed.
“Do you want more?”
“Yes! Yes! More! I want the real thing! I want to feel it!”
The way that he felt it with each thrust of the fingers, it told him that Remus knew exactly what he was doing.
“Oh, fuck!” Sirius groaned out, digging his face into the mattress. He was on the verge of cumming, his cock rubbing itself into the mattress, leaking heavily. He knew he was close, a few more of these thrusts and he was done for.
“Good boy, just keep it up,” Remus said, kneeling besides Sirius and looking at him intensely.
“Huh?” Sirius didn’t quite understand how it was possible for Remus to be here at the same time when he was sitting behind him, fingering him, before he realized both of Remus’ hands were free, now reaching out to caress his head, removing his hair from his eyes. But Sirius was still full, his prostate rhythmically stabbed into by… something.
“Such a good boy, work on your hips more, Moony! You’re not getting it all in.” Remus said as he leaned back and checked.
The dog yelped, pushing its giant paws into Sirius’ back, pushing him down into the mattress as it pushed his hips back into him.
Sirius yelped out at the realization. He held onto the mattress, trying to push the dog off himself, but Remus grabbed his hands and tried calming him down.
“It’s ok, you’ll be fine,” he whispered into his ear. “Just relax, Sirius.” He continued. “Relax and it will be good for you both.”
Sirius grunted out, his cock twitching and unable to hold it in much longer. He was cumming all over the mattress, as his insides clenched against the dog’s cock. He didn’t want to cum, all he wanted was to free himself of this monstrosity that was stabbing itself inside of him over and over again.
“That’s it,” Remus chuckled, reaching his hand over and tugging on Sirius’ cock. “Let me help you.”
He worked on his cock, getting the rest of it out of him, while Moony barked in the background, its hips moving faster and faster, body plastered over Sirius.
“No, I don’t want this,” Sirius whined out, trying to free himself. He clenched his body up, trying to force Moony out of him, but Moony just kept on pushing, the sudden tightness making the dog work even harder.
“Yes, you do, you want this, Sirius,” Remus whispered to him, as he squeezed his cock, smearing the spend over it. “You came here because of this, remember? To get stuffed.”
“Not… not the dog,” Sirius panted out, trying his best to explain.
“You agreed to this, there’s no way back now,” Remus smiled, caressing Sirius’ hair with his sticky hands. “Let me look at you,” he grabbed him by the chin and forced him to look up. “You’re such a good little bitch, just perfect for my Moony.” He smiled, his eyes glinting with excitement, and it was then that Sirius knew – this man was absolutely deranged.
At first, Sirius had hoped it would all be done soon, and he’d be able to grab his clothes and run away from this place without even putting them on – he’d just run, maybe without even picking them up. He’d run into the street naked, only in his socks and he’d never look back, leaving this crazy man and his dog in the dust.
But leaving didn’t seem to be an option, as the dog kept on, never tiring, thrusting its hips and cock into Sirius relentlessly. It was digging so hard, hitting his spot almost perfectly, that it made Sirius hard again, much to Remus’ amusement.
“Oh, look who’s out to play again,” he chuckled, pulling on Sirius’ dick. “See? You like this after all.”
“Fuck, no!” Sirius whined out. It wasn’t his fault that the fucking dog kept on hitting his prostate so precisely that it made him hard again. Just because he was hard didn’t mean that he liked it and just because it kind of started to feel good didn’t mean that he wanted this.
“Such a horny bitch for Moony’s cock,” Remus petted his cheek. He held his face and watched him intensely, focused on how Sirius panted, grimacing each time that spot inside of him was hit.
“Make it stop,” he panted out, desperate.
“He can’t stop,” Remus frowned. “He’s just started, why would you want him to stop when you’re both feeling good?”
“No,” Sirius shook his head, his mouth open. He could feel his drool dripping all over his chin, as Remus wiped it off with his thumb, making Sirius lick it.
Moony suddenly yelped out, throwing its body over Sirius, as the dog’s whole body weight pushed into him, making him flinch.
“Oh, is it time?” Remus asked, excitedly, peeking over to where Sirius and Moony were connected. He pushed his hand around the place, making the dog whine out and jerk its hips back, pulling Sirius with him.
“Ow!” Sirius screamed out from the weird sensation. There was something huge stuck inside of him and stretching him out painfully. And this wasn’t just the already enormous cock.
“He knotted you,” Remus explained. “I didn’t expect it to happen the first time, but here we are. Guess Moony really likes you.”
Sirius felt like his mind was scrambled. What did Remus just say?
“He’s pumping you full of his seed now,” Remus continued, his hand sliding underneath him. “Can you feel it here?” He asked, pushing his hand into Sirius’ pelvis, the dog whining out and pushing its hips up.
Sirius could feel the dog’s cock twitch inside of him, spilling itself all over his insides. It kept on releasing wave after wave of hot cum, stuffing him full of it and its giant knot prevented any of it from leaking out.
“Come on, Moony, get it all out,” Remus encouraged the dog. “Get your bitch full and round with it.”
Sirius grunted out, as another spurt of cum flooded his insides. He could feel Remus’ hands slide down to his cock, as he worked him through another orgasm, telling him what a good and obedient bitch he was, promising him loads and loads of Moony’s seed as a reward.
Which was certainly ridiculous, because Sirius didn’t want any of it. He didn’t come here to get fucked by a dog. He came here thinking he was going to do it with Remus.
“Aw, baby, all you had to do was ask, I’m sure Moony won’t mind sharing you,” Remus said.
Sirius wasn’t even aware that he spoke those words out loud, his mind not able to tell the difference between his words and his thoughts.
Remus unzipped his trousers and pulled his cock out – it was hard and leaking, obviously turned on from what was going on.
“Be a good boy, open up,” he said as he pushed his hips up, pulling Sirius’ head down to accommodate him.
Sirius moaned out, reluctantly following the silent order. He opened his mouth, eyes looking up at Remus desperately, as he took him into his mouth.
“Fuck, such a well-trained dog,” Remus whined out, pushing all the way in, reaching Sirius’ throat.
Sirius could feel the tears well up in the corners of his eyes, everything inside of him burning – his backside being split open by the dog’s cock, his throat choked up by Remus, getting it from both sides at once, desperately grabbing onto the mattress, his fingers digging into the fabric.
“Good boy, taking it so well,” Remus said as he thrust inside, Sirius’ nose shoved into his pubic hair. “I almost wish you were mine instead of Moony’s.”
Moony grunted, still not finished, occasionally letting a spurt of cum, reminding him it was also there, the giant paws resting on Sirius’ back.
“Do you enjoy this, as well, Sirius? Being so full of cock and cum?”
Sirius let out a muffled sound, still unable to speak as Remus was buried to the hilt inside of his mouth.
“Yeah, you do,” Remus chuckled, patting his head. “Once we’re done with you, you’ll be begging for more.”
Sirius tried to say that he wouldn’t, he definitely wouldn’t want any more of this, he never wanted it in the first place. As he tried speaking, his throat moved, twitching around Remus’ cock, making the man groan out in pleasure.
“Fuck yeah, make it tight for me!” He yelled out, throwing his head back and drawing his hips back, just to push them back inside. “I bet he’s even tighter on your end, Moony.”
The dog answered with a growl, squirming with its hips, almost as if showing Remus just how snuggly it was fitting inside of Sirius. It was buried deep, with no intention of leaving any time soon.
“Fuck, I won’t last much longer,” Remus whined out, steadying Sirius’ head with his hands as he started to cum.
Sirius felt like he was going to choke on it, being flooded with Remus’ semen, it pouring down his throat, as Remus made sure not to slip out of him.
“Come on, swallow it all,” he looked down at Sirius with a satisfied smile.
Once he was done, he finally let go of him, sitting down on the mattress next to him, exhausted. He gently slapped Sirius’ cheeks, wiping his face and making him lick the rest of the cum from his hand, practically pushing his fingers into his mouth.
“There, all clean now,” he smiled at him, wiping his hand into the mattress.
Sirius panted, his mouth open, and body spent. He slumped down on the mattress, his arms and legs shaking.
“Oh, I wish I could stay, but I got to get back to work,” Remus frowned. “My boss is strict with having his reports on time.” He said conversationally as he put his cock back into his trousers. “Moony will clean you up once he’s done, but he got a bit too excited, and he might get stuck in there for hours.”
Remus yawned as he stretched out, standing up. He gave Sirius a pat on the head and left.
Sirius closed his eyes, hoping that once he woke up, this horrible nightmare would be over.
