This is based on some hot art Seff did a few months ago over here. Basically, portal sex + hookup app is hot. A clip of that piece is used as the icon for the story with permission.

I've also got plenty more ideas for where this could go (besides Flora's ass) so let me know in the comments if you'd like to see more, or if you liked the shorter, quicker writing style I used here. Mandag_Morgen gave this a nice, sheen polish like he always does.

Flora hurled her keys into the key basket beside her and slammed the door shut. Her bag got dropped at the end of the shoe rack unceremoniously, and her skirt fell to the floor halfway to the bedroom.

She knew, she shouldn't be jealous, she shouldn't envy all the attention Kat got. But she wadid; every boy in the room turned their heads whenever Kat entered the room (except Mike), she caught all their attention. standing next to her made Flora invisible and now there were two of them. She was doubly invisible now there were two nearly identical but mirrored Kats, she could be standing in front of them and most of the boys would see right through her.

Flora pulled her shirt off and dropped it somewhere close to the washing basket, then tried not to look in the mirror while taking her bra off. That was the problem though, Kat didn't just have a pretty face, she had a fantastic rack to back it up. It was clearly where all of their eyes went when boys looked at either of them, and no lower clearly. If any of them had looked down or paid attention they'd have immediately noticed, and probably be put off by, the massive bulge in the mirror Kat's skirt. Flora hoped she was a shower not a grower, the poor girl might not have enough blood in her for that meat at full mast otherwise.

Well, screw Kat. Or rather, someone else could. Flora knew how to get herself some male attention and blow off some steam at the same time.

She slipped off her panties and kicked them backwards across the room into the laundry basket on her way to the toy drawer. There were two clean pairs of panties laid out over the top of some of her larger toys, the ones she used when she wanted to feel her stomach bulge out. She grabbed the blue and white striped panties and held them up to her phone to pair them.

The app bleeped approvingly and told her she could now wear the panties. Flora slipped them on and as she flicked through options of who she wanted to match with, wondered what exactly she wanted. She only had double portal panties, they could connect either her ass or pussy to someone for them to put their dick in. Normally she'd start with a few rounds in her ass. Letting four to six men fuck her there and cum in her would get her really worked up, excited, and feeling amazing because she knew how to really please a horny man. She couldn't cum from anal alone though, sadly, and so that's where letting someone go in her pussy came in. Two, occasionally, if the first one couldn't make her cum, three once. It was still good though, she liked knowing she'd gotten someone off, it made her feel sexy.

She selected pussy only on the app because she didn't need working up, she was angry and horny and wanted to cum. Maybe when she'd calmed down she'd let a few cum in her ass. She also selected large cocks and up only, ticking the checkbox for oversized. Heaven knows how the app actually determined cock sizes since no man could be trusted to tell the truth on that, but Flora liked to take big dick. She had a canine toy in the drawer with a knot as big as her fist, and a horse one as long as her forearm. She could take them both in her rear and she liked it that way.

Kathrin sat in her chair, watching the wheel on the matchmaking app spin, hoping someone would come up with a match. Her odds weren't great. Kathrin, that is the other Kathrin with the womanly bits, had no such problems. But she was mirror Kat, as Kat's friends had taken to calling her (she didn't mind, They were both Kat, but Kat had been Kat first so she got the nickname). She had a cock, and not just any, but an equine shaped and damn nearly sized cock at that. She was long enough she could just about give herself a tit job but the real problem was her girth, she had the largest size of portal fleshlight the company made and still only just fit through it. She went into the oversized category and very, very few people turned that option on for matchmaking.

At least few that were matching for free, that was already a small category that Kat assured her was very busy. When she put on her panties and match made for free she could get any dick she wanted, instantly. There were some paid options available but the two of them were far too tight on money for that. She could get herself off, it just took much more effort to jerk the whole of her dick at once.

The app blinked at her that it had found a match with a countdown of how long she had to accept it. It didn't tick down even a single second before she hit yes. Most days she couldn't get anyone at all and wasn't going to turn down the opportunity.

Kathrin grabbed her fleshlight off the table in one hand and a bottle of lube with the other while her cock throbbed needily between them. She slathered it in the silicon gel liberally, it didn't matter where it was going, she'd probably need it. The app on her phone chimed happily that it was sending data to the fleshlight and a few seconds later a portal connection was established between her and someone's panties.

A soft pink pussy appeared on the other end of the portal, surrounded by smooth white fur. Kathrin glanced over at the profile on her phone for any notes, it was almost entirely anonymous (meaning they were matching free as well) and the only note was that she likes big dicks. Well, that made for a good match then.

There was no note about wanting foreplay (which was its own matchmaking category anyway) so Kathrin defaulted to the normal etiquette for portal sex, putting her dick straight in. She lifted her fleshlight tube up to the tip of her cock and gently rubbed the tip of it against the pussy lips. Her cock had a flat and flared end, so it was only polite to let whoever she was about to fuck know just what was coming.

She felt the soft lips relax, so took that as her cue that whoever she matched with was ready and gently pressed the fleshlight down over her cock. Kathrin was big, and that usually meant some period of adjusting and stretching with whoever she matched to, but today the pussy lips just parted in her way and slipped over the flared tip of her cock. She moaned softly and her dick throbbed excitedly as she pressed downward, her length slipping into it half an inch at a time as though her excessively massive cock were nothing.

Flora humped back against nothingness. She'd gotten onto her hands and knees on her bed as soon as she'd felt how big the head of this cock had been. If she'd been in any way disappointed, it was only on how slowly they were putting it into her. She squeezed down on the cocks tip, trying to massage it, maybe encourage whoever this massive schlong was attached to to hurry up and put it in her, because all her humping was doing nothing when the portal was inside her panties.

That didn't work, so Flora reached over for her phone and thanked the foresight she'd had to take it with her to the bed.

"Put it in already."

The message pinged up on her phone from her match. Normally at this point they'd be telling her to be more gentle, so this was a very pleasant surprise. Kat couldn't bring herself to be any less gentle. Even if she had a monster cock and wanted to use it, she still didn't want to hurt anyone, so she sped up a little bit but not too much.

It didn't matter, her cock just slid in, going deeper and deeper with no trouble whatsoever, warm flesh sliding over her shaft and enveloping it faster and more easily than she'd ever seen before. She was throbbing with excitement because she was already deeper than she'd ever managed to go in a pussy before and was now worried about going too deep.

Kathrin's median run on her cock, the halfway point of it, slid in with no trouble at all. She'd barely begun and was already in heaven, no one had taken that before. She caught herself about to hyperventilate from excitement because she'd finally found the perfect match.

Flora let out a sharp mewl and squeezed down tight when the cock bumped into her cervix. She'd been expecting it, and it was no less painful than any of the times she'd hit it with her toys, but no one had ever gotten it with their dick before. She had been the one that told this guy to hurry up and put it in so she wasn't going to get angry with him for doing so.

"Marked it, sorry, won't hit again." Came the message on her phone.

They'd marked it, like on their dick? They still had length left after that to put in her?

Thoughts on what she might have been missing out on were forgotten in an instant as that massive, giant cock pulled itself back and thrust forward again with vigour. It had only been a few inches but Flora still fell forward into her pillow and bit down on it because it was an amazing, filling few inches that repeated itself again a second later and then just kept going over and over again.

Flora had been fucked plenty of times, she'd had many a dick that made up for its size by what they did with it, and a few larger ones that did little more than cum in her, but this was both at once. It was huge, it was stretching even her, and it was now pounding her senseless with limitless energy.

The fleshlight slapped against Kathrins hand every time she brought it down, burying her cock into the soft pussy. She'd wrapped her hand around half her cock as an easy and convenient measurement of how deep she could go without hurting her match.

And now, with her depth marked and the first fuck she'd ever had that could take her this easily, she lost all self control and began stroking the flesh light over her dick as fast as she could. She usually had to be so gentle and careful not to hurt her partners and now she'd finally found someone who could properly take her she was letting loose. She was panting, her tongue was laid out the corner of her mouth like her dog half and she was moaning urgently, needily. Kathrin often let out soft little moans of pleasure while being fucked but now, with most of her cock burried in someone that could take it, she was moaning desperately.

Flora moaned into her pillow. She wasn't afraid of anyone hearing her, she just couldn't move her head to the side to moan freely. She'd started on hands and knees but first her arms, and then her legs had given up on supporting her. She was a moaning wreck splayed out face down on her bed, legs spread wide. Arms somewhere up by her head but unable to hold on to anything.

About the only muscles on her body that were responding were, ironically, her pussy, which was trying to clench down around the massive cock pounding away on her because even this was not actually stretching her to her limit. She wanted to reach around and rub herself desperately because she was getting the fucking of her life and wanted to cum from it so much, but the portal panties wouldn't have let her anyway, even if she could have moved her arms so she'd have to just cum from the thrusting.

It wasn't going to take long.

Kathrin slapped the flesh light down again and again because there seemed to be no limit to what this girl could take, no matter how hard she thrusted, bucking up in her chair into the toy and the pussy, she took all of it and then squeezed down around her because she wanted more. This was perfect, this was the best fuck she'd ever had and the only thing she wanted more than for it to go on forever, was to cum as hard as she could.

She was going to cum hard, very hard. The twinge of sensation ran through her cock as her heavy balls pulled themselves up closer to her, muscles between her legs she barely knew about squeezed down around her prostate and send a wave of cum running up her cock and deep into the girl.

Kathrin leaned back in her chair and cried out to the whole apartment as another jet of cum squirted up her cock and out into the pussy.

"Ahhh, AHHHHhhhhhhhhhh!"

She screamed in ecstasy. Kathrin wouldn't care, they were both moaners and they both knew it. She felt her pelvis clench and send another wave of cum up her cock and moaned some more.

Flora screamed into her pillow, her paralysis had lifted as soon as she'd started to cum. Besides her pussy clenching down to keep hold of every drop of seed, the head of the massive cock flared outwards, expanding and stretching her at her deepest point. She would be lying if she claimed it didn't hurt a little bit but she was so deep in the swirls of orgasm it just mixed into the emotional soup. She clutched onto her pillow and held onto it for support as she was wracked by the best orgasm ever, while filled with the biggest dick she'd ever known, and was now full of more cum than she'd ever been filled with before. This could go on forever if it wanted.

It didn't though, much to her disappointment. Even as she began to calm down from it, the pleasure fading and her vision widening, she wanted more of it, she wanted this dick in her as much as it possibly could be, and as soon as she had the strength to, she reached for her phone.

Kathrin leaned back in her chair and let her hands fall to the side. The fleshlight sat on top of her cock and wiggled back and forth with it as she tensed and relaxed while squirting the last few drops of her orgasm out.

That, had been, the best. And she had no idea who she'd just fucked senseless.

Kathrin picked up her phone and checked the profile of her match. There was no name or face, so a free user like herself, but as she flicked through pictures of tiger butt and leg, she noticed nothing above the waistline was shown. Perhaps they were shy of showing boobs? Maybe they were flat and embarrassed about it. Laura never seemed to mind, but Flora had always been envious.

That didn't matter, she scrolled down to the likes section and immediately noticed that at the top of her list was anal.

Her cock throbbed again as she tapped on her phone.

Flora could barely see her phone as she put it in front of her, so blissed out she was. She'd been trying to read the profile of whoever was on the other end of the cock filling her up right now and wondering what the hell else she would do with the evening. She'd been planning to match with her ass after cumming, get herself worked up for round two, but what else would compare to that fucking today? Even if she did rather like the idea of getting railed under her tail a bit.

Then an alert popped up on her phone from her match.

'Partner requesting switch to anal sex.'

The automated message was cold and lacking any of the excitement it was causing in her. That would compare, it would fill her quite nicely in fact. She'd taken bigger toys, she could take this dick all the way.

Flora hit accept.

Kathrin frantically packed all of her pillows and blankets onto the corner of her bed as her fleshlight switched over with a magical fuzz to her partner's rear.

She'd said yes, she'd accepted anal.

Kathrin had a very long dick, something she was being reminded of as she put her fleshlight on top of the pile of pillows and lined herself up for it with her other hand. No one had ever taken her full length in a pussy, but twice someone had been able to take her in their ass, albeit only for a moment.

To say that Kathrin was constantly horny was a massive understatement at best. She'd been told that for most people, arousal was an emotion that came and went, but for her it was a constant part of her life. She could get an erection at any moment, as soon as she desired, because she was always turned on. Even when she could get sex, she usually found herself too long to get all of herself in, so to her there was something truly magical about being able to actually use the last few inches of her dick. Holding the base of it just wasn't the same. She wanted to fuck and fill someone and hilt her cock in them and maybe, just maybe, if this tiger girl's ass were as well practiced as her pussy, today could be the day.

Kathrin squatted down with her legs either side of the corner of her bed, straddling her fleshlight and lining up her tip with it. Inside, on the other side of the portal, a tiger's tailhole stretched itself in anticipation of her and she pressed herself up against it and pushed herself in without hesitation.

Addendum: this was the best fuck Flora had ever had. It had only just begun but that monster cock was stretching her out wide as it ploughed into her, and its wielder was sinking it deeper and deeper by thrusting it in. No gentle filling, they'd started with the pounding and every time they pushed back in they went a little deeper.

Flora rolled over onto her side, this was no time to sit back and moan, she had dick to take and an ass to stretch. She lifted up her right leg, pointing it at the ceiling and grabbing it with her hand, holding it up high to make more room under her tail. She was running on more than just pleasure now, this was about pride, even if she was moaning freely. She might not have the best bust, but she had the best butt and she had it where it counted, right under the tail.

Looking down she began to see the first signs of her belly bulging outwards. A small bump popped up in the middle of it with each deep thrust, and as the cock continued to work its way deeper that bump became less small. Flora marvelled at it for a minute, because she'd always loved the way her very biggest toys looked like her body could only just contain them, but this was somebody's dick and it kept going deeper.

Flora grabbed hold of that bump and squeezed it, because it had stopped disappearing, only going from small to big.

Kathrin moaned with every thrust she made as she humped away at the pillow mountain and most importantly, the slick and deep tail hole her cock kept disappearing into. A pressing sensation seemed to grip down around her tip, which was weird because it should be deeper than any anal muscles by now, but also because of only grabbed the bottom of her dick. It took a few more slightly slower strokes before she realised she was poking her dick against the front of the tigress' belly and she was then stroking it through her front.

A little bit of precum leaked out the end of her dick when she thought about that, and then she went back to thrusting with even more vigour because this asshole needed to be filled.

Kathrin watched with anticipation at the base of her cock as she gave the last few thrusts she needed to get all of herself into the tigress. She let out a loud and satisfied groan as the last of her cock disappeared into the white fur and her belly pressed up against it.

She looked down in disbelief as she hilted herself in this tail hole and held it there, no messages asking for her to pull back, only satisfied squeezing and the rubbing hand over her tip. At that moment, Kathrin decided that this rear needed to be given the best pounding ever. She pulled herself backwards, all the way to her tip, and then thrust forwards as hard as she could, sinking every single last inch of her cock into that warm and willing hole.

Flora made noises, they were moaning, but also gibberish. She was still holding her leg up and she was going to keep it there, because right now it was a matter of pride that no matter the fact that her rear was getting the most amazing pounding it had ever experienced, she could hold her yoga poses and keep her butt spread.

She was being tested to her limits though, this was the pounding of a lifetime, her belly kept bulging outwards with each deep stroke and she'd stopped squeezing it because her spare hand was under the panties, furiously rubbing herself because she wanted to cum to this when it finally filled her.

Kathrin had poked her head around the door to see what all the yelling was about, and was now voyeuring as her mirror counterpart slapped away at her flesh light, panting and moaning as her massive cock disappeared into the depths of the portal over and over again.

Mirror-Kathrin didn't even notice the other Kathrin; she was too focused, too blissed out on the feeling of this tail hole utterly enveloping her cock with warm tightness over and over again. She pounded as hard as she could, her thighs and calves ached and it simply didn't matter because she was hitting herself from her tip with every stroke. This was the best sex ever and it was steaming towards its inevitable conclusion.

The feeling, the tingling sensation, grew outwards from the base of her dick, spreading up it and outwards to her prostate and balls. For once she held it, because for the first time in seemingly forever she wasn't trying to get off before she injured her partner or because they were already hurting. Instead she let the pressure build and build until she couldn't bare to hold it band any more. Then, with a cataclysmic rush of cum, she unleashed her orgasm with an uncontained howl of pleasure. She kept thrusting as she pumped load after load of hybrid seed into the tigress, plunging it deeper, timing her strokes to spurt at the deepest point because she wanted this tigress booty filled to the brim with her love and juices, all of it.

There was no denying the unnaturalness of her cock, and there was likewise nothing natural about the size of the load she now pumped into her partner. Thick loads of it jetting down her cock to fill the tigress's rear.

Flora had done enemas before, and she'd even done some playtime with them, but never before now had she seen her stomach bulge outward quite so much as this. Her whole lower belly was ballooning slightly, as though she were a month or two pregnant, with just the cum from this cock. She was very glad for the enchantments that she'd added to the panties, those that kept anything from leaking out of her rear, because no matter how tightly she squeezed down on that cock, there was simply no way she would be able to keep all of this load inside of her.

Kathrin collapsed forward face first. She toppled over the pile of pillows and landed inelegantly half spread out over the corner of her bed where she stopped, unmoving. She lay there for a while, wholly unaware of the passage of time, only that her dick was still enveloped by the tigress butt that could take all of it.

"Sounds like a good lay." Her mirror counterpart noted, setting a glass of water down on the bedside table, that she couldn't reach for yet because she couldn't move.

"Mmhhhmmm." Was the extent of noises that escaped her.

"Seems like they liked it as well." Kathrin noted, holding up mirror Kats phone in front of her where she could see it. There was a friend request from her partner, so they could match together again privately whenever they both liked. Other Kathrin, noticing mirror Kathrins lack of movement, took it upon herself to tap accept, and the little 0 that had always been in the corner of the app turned to a 1.
