Even outside Jay could hear the base thump out from the club.
It was "the hot new place" in the city, the various financiers, insurers and other professionals had decided it was a change, a bit grungy and exciting in its exaggerated cosplay of a nightclub one would find outside of the financial heart of a dying empire.

The group bundled in, a board gazelle with a thick UV stamp pen marked each one after taking the fee, no rumpled notes here; a quick efficient tap of a platinum or black card.

"Shots!" Jonty was the lead, and most enthusiastic to relive his days leaving the hallowed halls of a prestigious university to slink off to a club "the townies" went to (the actuality was that it was entirely other students, all pretending to be from the town and not an ancient and expensive university). Pressing through the early evening crowd of commuters desperate to get shit faced before the last train they made their way to the bar.

Passing out double shots to the group who had huddled around to collect their drinks and shout their actual drinks orders he surveyed the crowded and noisy scene of other punters trying to catch the bar staffs attention.
At least that experience was the same.
Feeling weird about the experience Jay obediently took his shot and waited for the others. It felt wrong to be in even a pretend-crap club in a suit.
He hadn't been to a club since he graduated.
This was very much like a better grade of those. The floor wasn't sticky, the prices were higher, toilets where probably clean and everything in good condition still.

They drank and passed the time, he stood and watched the heaving mass of bodies on the dancefloor when he caught one in particular.
A petite canine in a tight short black dress gyrating and rolling her body to the music.
A distinctly patterned brown and white merle...

"Jaaayy man, have you seen the one on the dancefloor? She looks just like your girlfriend" Tolly leaned in and pointed.

"What? Huh? No, I, she doesn't really?" He tried to laugh it off badly

"She's tiny, there's no way she's Jay's girlfriend! She must have used a fake ID or something, there's no way she's Jay's girlfriend. Look at her" Gryph objected

"No, look. She's got the eye patch and the colours. I don't know how big Jay's girlfriend is. He's said she's pretty short" the canine shot back

"Short, yes, but that's more than just short, look at her"

"Hay man, if there's grass on the pitch play ball, who are we to judge Jay if he likes them smaller? She's here and I don't think the bouncer would slack off and let her in if it wasn't fine. But you tell me that doesn't look just like Jays girl?" Tolly motioned again at the dancing canine.

"That's disgusting Tolly, I don't ... Please never say that again... But I suppose there is a resemblance... And, I suppose she could just be unlucky" Gryph conceded.

"Well. If she's not your girlfriend, I'm going to ask her for a drink!"

Without thinking Jay's hand caught his dirty minded, and clearly inebriated, college by the arm.

"It may be her, the lights crap and I have no signal. She's in town, and, anyway, I need a refill too..."

He was heading over before the other canine could object.

What the fuck was his sister doing here? She had no right to be here! Let alone look so hot in that dress. A tight ball of jealousy formed in him for all the other guys enjoying his sister in such tight and revealing attire.

He eyes went wide as he reached her, then a naughy grin chased over her muzzle

"Fancy meeting you here. Didn't know you were a clubbing type." She called up, having to stand on tip toe to make herself heard, even with the high heals she must have borrowed she was short.

"Nor I you" he could feel his colleagues stare, she must have caught his glances at them as she grabbed his muzzle and pulled him in for a firm snog, eliciting a set of hoots from his drunken compatriots.

She grinned as she broke the kiss, the others she'd been dancing with had looked ready to protect their diminutive friend until they saw her greet the canine with a kiss.
They all looked more like they belonged here which had probably helped his sister get in.

She started to grind and gyrate against him, her ability to dance and move her body in such a sensually serpentine manner was disconcerting.

"When did you learn to dance like this?" He couldn't let his curiosity go un-sated as he badly tried to return the dancing.

"Ten or so years of ballet and dance? Don't you remember?" He had to confess, both of them had so many after-school clubs over the years he'd not kept track of hers. He knew she did extra computer stuff and some hockey. He thought she'd stopped doing dance ages ago, he'd been dragged to a single show when they where both pups and complained so much he'd bern exempt from all others. It did explain a number of things though...

Feeling his sister bump and rub against him in the half light and the revealing dress that clung to her petite form so well, her tail slipping between his legs, he couldn't help but react. They'd not been able to see eachother for weeks, not been able to fulfil their desires for their sibling for so many days. He felt himself start to rise out of his sheath.

"I'm going to get a drink" he gabbled before he could get too lost in the moment and end up with an embarrassing tent in his suit trousers.
He had established the small merle collie on the dancefloor was his territory with that kiss, to both his and her friends, so hopefully she'd be safe from the other predators lurking around the place, like Tolly.

"Great, I need one too!" She chirped and latched onto his arm.

Reaching the bar he got himself a beer, he wasn't much of a fan of it but wine in a club would get him ridiculed by his friends and he didn’t want to pay that much for anything else.

"And for the little lady? Same again?" The mouse barman leaned forward, clearly she'd ordered before and made an impression. He suspected anyone of her build and apparent youth would.

"Please! He's paying though"

"Coming right up, tap there mate" the mouse set to work on getting the drinks, hers involving several alcopops and spirits as well as a can of violently blue Pwr Drnk.

"The fuck are you doing?!" He hissed to his sister as she watched the mouse work.

"Ordering a drink?" Like butter wouldn't melt...

"It's ... You..."

"I'm here, so it must be fine. Wouldn't be here if it wasn't. Anyway, it'd look really suspicious if someone who looks like me ordered anything but a party girl drink. If I asked for something I'd like, a whisky neat or a soft drink, they'd be more suspicious than if I order what all my friends do, which is strong sweet cocktails in bright colours" he hated she was correct.

"That's not the point. Do your friends know?"

"Yeah? Pretty hard to miss the smallest one in the course is probably... Y'know, and that I told them... It was Sasha's idea actually I come" she motioned to a tall zebra woman. That was when it clanged into place. She was doing summer short courses at the university, some kind of get ahead thing for nerds, so they’d all be students or freshers (soon) and she’d be with the younger nerds doing it to get ahead. Though when she got a fake ID he didn’t know, nor did he much want to.

"Mum and dad will kill you"

"You won't tell them. What, you found me out with friends in a club with an /ID/. How'd you think they'd take you fuck your pup sister?" She hissed back into his ear, dropping down from the metal bar rail she’d been standing on to take the fizzy electric blue cocktail as it arrived on the bar, a wide happy grin as if she hadn't just threatened to ruin his life.

She was already heading to the table his friends where camping around and they had spotted her before he could divert and avoid it.
Thankfully they chatted and seemed aimiable to her, although she did perch on the foot rest of the bar stools to be tall enough to to really chat and lean on him in a manner she could still tease him as she bopped along to the music, all playing up the party girl act.
Thank fuck it was dark and her body was in the way as he tented his black trousers.

Soon enough, too soon in his opinion, she finished her drink and returned to the dance floor with her friends. He wasn't even a quarter of a way though his beer.

Watching her depart Gryph made a comment about how small she was.

"It's a hormonal thing" he dismissed it. It was partly true, she was the smallest in her year due to her heat condition and always would be.

"A lack of maybe" Tolly snarked. He couldn't be bothered to argue with them and their gross comments.

Finishing his beer he chatted and watched his sister dance and get thought another cocktail. She was clearly tipsy now as she wasn't rebuffing guys so often, her friends often doing so, despite matching her drink for drink.

Deciding for both their sake he needed to be there he returned to the dancefloor.

Uncomfortably shifting and doing his best to dance Melody carried on, dragging against him and moving with the songs in just the right way.

/She keeps me up/ "she sure does" he thought as the DJ seemed to start a playlist to target him and his predicament
/Bad girlfriend/ "on the mark there mate" he mentally groaned.
/Porn star dancing/ he couldn't help but shoot a glare at the DJ booth, but like many the bloke was just on social media and his as shuffle on a stream did it's this.
/Bad touch/ "that's it" he gave up, he was solid and would gladly fuck her then and there. He caught her and leaned in for a kiss, forcing his tongue into her muzzle he tasted the alcopops on her breath. It was his turn to grin wickedly at her.

"Bathroom?" It wasn't really a question but she wasn't going to say no regardless, she nodded, cheeks flushed and panting.

He gripped her hand as she attached back to his arm, hanging a little more tightly this time as they wound to the bar. With a wink the barman directed them to the back of the bar.

Down a corridor that he felt was probably a staff only, he reached the single occupant bathroom he detected his sister-cum-girlfriend from his arm and unzipped himself.
Pushing her shoulder down so she knelt before him. She was already nuzzling him as he pulled his hard cock out. Seven inches of collie cock rested on her muzzle as she slowly lapped over his root near his knot and sheath. He was in no mood for foreplay, he gripped her head, yanked back, held his cock and brought muzzle and meat together.

She had come out to a club she shouldn't be at, had drunk more than she could possibly handle for her size, and put herself at risk of some other dog or carnivore grabbing her.
Lucky for her he was the predator who found her first.
She gagged a little at the surprise but years of sucking her big brother off had trained her throat well.
He huffed as he started to slide his cock out of her muzzle, building up pace as he started to enjoy himself after all that teasing.

As he used his sister's muzzle as a fuck toy he realised he had been thinking of the other guys who may come for her as predators, as hunters, when she had dressed like tha: she didn't normally dress like this, such a short revealing dress, she had deliberately chosen a provocative outfit as she had been on the hunt too.  He was certain (or maybe the alcohol was) that she had deliberately dressed in this way, come out to a club like this danced like that as she was hunting too.
That made him angry.
Not the deliberate risk, it was that someone could have impinged on his territory.
Some other guy could have been with her here and now, dick in her throat, and not him.
She was /his/.
He'd been first to claim her.
If he had given assent, known the guy, gotten a measure of him, sure he could share. Afterall Tilly had as much claim to the collie bitch on her knees sucking desperately on his cock, hand shoved up her short dress, as he did.
She moaned around his cock.
These where his moans, his alone.
His sister.
/His/ sister.
His girlfriend.
His girlfriend sister... His puppy sister girlfriend. *His*
Ancient deep parts of his canine brain flared with territorial instinct. Some other dog could have entered his territory and had his bitch.
The bitch he loved.
The bitch he'd claimed the virginity of and bred regularly.

Who was on her knees flogging herself off as she gave him a blowjob.

She was the best sex he'd had.

And this was one of her best blowjobs.

He'd have to get her drunk and fuck her more often.

He felt himself getting close as her tongue lashed and writhed over him.

He looked over at the long mirror on the wall.
Her high heels splayed beneath her, black dress pulled up and rumpled as she worked herself off with one hand, the other wresting on his black suit trousers.
Only his front was visible, now dull Oxfords, the tails of his smartly tailored suit jacket, white shirt, no tie, fly open and hanging slightly to the sides, grey boxers, white sheat, red rocket vanishing into white brow/grey muzzle.
It looked like a scene from a porno.

He watched he suck him off. Her hand move between her legs as she touched herself.
He enjoyed how much she liked giving him head, it pleased him she got off to it. Some women he'd been with didn't touch themselves as he used their muzzle.

He shifted as his traitor brain suggested that the border collie in the mirror was some other dog in his territory.
He gripped her head fur harder, started to thrust forward into her as he guided her head against him faster and harder.
No, it was him. It was him claiming his bitch. HIS sister.

"Close..." He warned her, feeling her hand shift towards his knot.
He would make sure all the others would know exactly who's girlfriend, who's sister, who's territory she was.

Pulling back suddenly he reached up with his free hand and grasped his cock, angling it to shoot plentiful ropes of watery collie cum over her face and muzzle. The white liquid splattering over her grey/brown fur, matting it.
Her small hand held his knot, as she simulated a tie, his own covered hers as he aimed.
After several bountiful squirts he started to soften, and the flow stopped.
His smeared off the last of his cum on the side of her muzzle, zipped himself up and left her sagging on the floor.

"Mine"

She knew where he lived if she wanted a taxi, but she should suffer her poor decision to drink so much with her friends and suffer her first hangover with them.

It was a lesson she needed to learn.

"Mine"
