Chapter 5 Pt.2

Oh God yes!" Haley moaned, grabbing onto her baby sister's dark hair so she could push Alex's face firmly against her cunt.

This of course had Alex glaring up at her, Haley briefly giving her sibling an apologetic look before she closed her eyes and covered her mouth with her free hand. Haley couldn't give a verbal apology, not when the urge to moan was so strong. Hell, Haley wasn't sure she could get a single word out before moaning, groaning, whimpering or gasping in pleasure, which was definitely Alex's fault as despite being obviously annoyed with her that didn't last. Or at least Alex forgot it in favour of licking Haley's pussy, those licks making it impossible for Haley to apologise, and her baby sister's talented tongue quickly made her forget what she should be sorry about.

All Haley really knew was that her pussy was being licked by the most wonderful tongue she had ever known, a tongue which knew exactly what she wanted. Or more accurately the tongue's owner knew, that owner of course being her kid sister, Haley's super smart sibling eagerly tonguing her twat for several wonderful minutes, Alex making sure to hit her clit with every stroke of her talented little tongue. Whenever Haley wanted more Alex picked up the speed and the force of her licks, eventually slowly pushing her tongue as deep as it would go into Haley's pussy, and then thrusting in and out.

During the gentle cunt lapping Haley was so blissed out from pleasure she just leaned back against the wall of the toilet stall and became lost in the sensations she was feeling. With her eyes closed it was pretty easy. But, thanks to Alex's assault on her clit and picking up the pace of the licking faster than usual, Haley soon found herself aching to cum, and unlike when they were locked away in their bedroom, and ideally home alone, Haley didn't trust herself to tell her kid sister what she wanted without screaming the place down. Not when her little sister was eating her pussy so skilfully. Luckily Alex remembered they were trying to have a quickie, and gave Haley what she wanted without needing to be asked.

When Haley felt Alex's tongue entering her pussy her eyes flew open and she was greeted by one of her favourite sights in the world, that of her little sister on her knees with her face buried in between her legs. The combination of that feeling and that sight made Haley cum so hard, the brunette with blonde highlights screaming into one hand while she used her other to push her baby sister's face as deep as it would go into her cunt, the brunette with the dark hair happily taking the hint and increasing the speed of the tongue fucking. After Alex had swallowed as much cum as she could, of course.

As Alex was now an expert at eating pussy, or at least an expert at eating Haley's pussy, she was able to swallow at least the majority of her big sister's first climax. Sadly she couldn't say the same for the ones that followed, although Alex was proud that her face became drenched in the liquid as her knowing tongue made Haley squirt in her face. Which should be difficult to explain away, although Alex was pretty sure she could adequately wash her face so that their dates wouldn't notice. It wasn't like they were that smart anyway, which wasn't surprising as apart from Alex her sister seemed mostly to date idiots.

However, no matter how dumb they were surely they would notice if they were gone a long time? And if they didn't in member of staff possibly could, so really Alex should be restricting herself to making Haley cum only once, twice at most. Unfortunately she became lost in her desert, Alex constantly switching between sucking the cum out of Haley's cunt and tongue fucking that wonderful little hole. Even when she heard other women entering the bathroom to use the facilities Alex just kept her tongue buried in Haley's snatch, quickly resuming the frantic tongue fucking the moment she heard the other women leave.

This went on for quite a while until the sound of knocking filled the room, followed by the door being opened slightly and a familiar voice called out, "Are you guys okay in there?"

"Just give us five minutes." Haley called out.

"Oh, okay." One of their dates replied, Alex honestly couldn't remember which.

Having finally pulled away when she heard him the first time Alex went into panic mode, but was immediately calmed when Haley leaned down and forcefully kissed her. Which wasn't fair, because Haley was an awesome kisser, and she knew just how to make Alex melt. The fact that Haley was tasting her own cum and pussy cream on Alex's lips and tongue only added to the distraction, but the younger sister quickly remembered it when the older sister broke the lip lock and started kissing her neck, and all over her face to get more of her own flavour.

"Haley, we need to go!" Alex hissed.

"Not until I've fucked your fat ass!" Haley growled softly.

"We don't have time." Alex insisted, trying to get up.

Before she could Haley smacked her big butt as hard as she could and, somewhat menacingly for her, growled, "Bend over!"

For a few long seconds the two sisters stared at each other, then Alex whimpered, quickly turned around and bent herself over the toilet seat. As she did so she undid her pants and pushed them, and her panties, down to her ankles, exposing her plugged filled ass. Not because Haley had ordered her too, although that made her embarrassingly wet, but because honestly Alex just desperately wanted to be butt fucked, even if it meant risking her secret relationship with her sister, which had quickly become the most important thing in her life. To her credit Haley quickly retrieved her favourite harness from the handbag she had brought with her and strapped it around her waist, her eyes locked with Alex's ass the entire time.

Haley normally would have spent some time savouring the sight of her baby sister spreading her meaty cheeks for her and exposing her cute little butt hole, and maybe then like an hour with her tongue up Alex's ass, but they were already pushing their luck. She still couldn't resist providing Alex with a little more preparation in the name of spitting in her open back hole once she had pulled out the butt-plug, however after that she quickly pressed the tip of her strap-on against her kid sister's ass hole and pushed forwards, Haley almost literally drooling as Alex's forbidden hole quickly swallowed the head, and then eventually the full-length, of her cock.

Considering she had been butt fucking her baby sister every single day for two weeks it was no surprise that Alex easily took her length. Well, she did squirm a bit, and she cried out, whimpered and gasped. Still there wasn't a single sign of complaint, Alex even moaning as her fat ass was filled with cock, which made Haley grin with pride. She had done the unthinkable. Haley had turned her goody two shoes brainiac of a sister into her personal anal slut, and it might just be the greatest accomplishment of her life. Not that it really had much competition, as in the long run Alex was always the one who was going to do something great with her life, but Haley would happily take this, her little sister bent over a toilet seat and taking her strap-on cock up her big fat ass.

Haley was awoken from her feeling of pride when her thighs bumped against Alex's meaty cheeks, announcing that she had finally got every inch of her dick inside her little sister's big booty. Not that the anal penetration took that long, but even with the daily ass fuckings she had been gleefully giving her kid sister Haley thought it was best to air on the side of caution and not ram every inch of her dildo up Alex's ass in one go, even though she was very tempted. So despite the lack of time they had she slowly inserted her dick into her baby sister's butt hole, the fact that Alex was still spreading her cheeks giving Haley a perfect view of inch after inch of dildo disappearing into her kid sister's ass hole.

Now she had completed the anal penetration Haley had to grind her teeth not to taunt her younger sister like she usually did, especially when Alex let go of her ass cheeks, just like Haley had trained her to do. Which again made Haley want to taunt her little sister for knowing her so well, specifically that Alex knew that her big sister loved feeling that big bubble butt of hers jiggling against her thighs as she fucked her baby sister up the butt. However she couldn't do that. Shouldn't do it. It was risky enough when their family was downstairs, but now anyone could come in at any second she couldn't afford to get carried away. Not when they had already almost got caught. However, there was maybe something she could do, Haley grinning again as she lent down so that her boobs were pressed into Alex's back and that her mouth was pretty much pressed against her kid sister's ear.

Alex let out a soft moan as she felt Haley's perfectly sized tits pressed into her back, her sister's pleasant weight on top of her and perhaps most of all the hot breath on her ear. It also made her panic, and blush. Haley love to talk dirty during sex, and as much as Alex had grown to love it too despite how much it embarrassed her at first, now was not the time or the place. But likewise it wouldn't help matters if Alex scolded her sister to be quiet, because someone could come in at that exact moment and hear that, which was almost just as bad, so she decided to stay silent and pray that Haley wasn't that stupid. Her prayers went unanswered.

"Your ass is mine sis!" Haley softly growled in her little sister's ear, "Your big fat gorgeous ass is all mine, and now I'm going to wreck it."

Blushing even more than before Alex opened her mouth to tell Haley to shush. That proved to be a mistake as it coincided with Haley slowly pulling her hips back and then quickly snapping them forwards, making Alex let out a loud moan and then cry out with pure pleasure. Ironically for her trouble Alex found herself being the one told to shush, Haley having the audacity to do that after reaching a hand around and covering it tightly over the younger girl's mouth.

"Shhhhhhhh." Haley scolded, unable to stop herself from adding with a whisper, "Try not to let the whole restaurant know I'm taking what's mine."

Frowning and then groaning in annoyance Alex did her best to stay quiet as Haley quickly established a steady rhythm, fucking her butt with short, sharp thrusts while keeping her body on top of her. After a matter of seconds any annoyance at Haley was forgotten as Alex became grateful for every thrust her big sister gave her, the darker haired girl struggling to keep her moans of pleasure to herself as her slutty ass quickly adjusted to having the other girl's big strap-on cock inside it and she felt nothing but overwhelming pleasure from the latest in a long line of butt fuckings. Butt fuckings given to her by her big sister, this one in a public bathroom while their dates waited for them, that fact no doubt helping Alex to relax.

To be fair Haley was getting better with every ass fucking she dished out, and having the older girl's body pressed against her during the sodomy was an extra turn on, as was the hand which wasn't covering Alex's mouth, Haley first using that hand to slide over her sibling's body before of course concentrating on Alex's ridiculously big tits. Then there was the butt-plug, which had done its job and stretched her out, and all the work Haley's tongue and fingers had done before they went out. But Alex couldn't deny the fact that she was just a natural anal slut. Hence why right from the beginning her rectum had easily relaxed and accepted what it was always supposed to be, a fuck hole.

As if reading her mind Haley softly purred into her ear, "This is what you're for Alex! Mmmmmmmmm, you were made for butt sex! Yessssssssss, take it my little anal whore!"

Alex moaned extra loudly against the hand that was covering her mouth and pushed herself back against Haley's thrusts. She then tried begging Haley to fuck her harder, but they came out too muffled at first, Alex not daring to raise her voice any higher in fear of getting caught. Then the urge to cum just became too overwhelming, Alex telling herself she was doing the right thing as if they waited any longer their dates would surely become curious and check up on them. However just as she was about to force Haley's hand away from her mouth she heard the bathroom door open, followed by footsteps.

This time it was only one pair of footsteps, but it would only take one person to discover them to create a crushing moment which would haunt the two sisters for the rest of their lives, and maybe even put an end to their ultra-forbidden affair. As that was something neither sister could stand Haley stopped the butt fucking the second she heard the door open, although she made sure to leave every inch of her cock buried in her little sister's big butt. Not that Alex had a problem with that. Oh no, the feeling of that huge dildo stretching her rectum, and Haley's body pressing on top of hers was helping keeping her on the edge of orgasm. It was even a little comforting. Well, at least the part where Haley was pressed against her.

With the room now silent except for the sounds of the other woman the two sisters clearly heard the newcomer make her way to one of the stalls, entering it and locking it closed before beginning to use it. Just as Alex began to think they would be alright Haley slowly pulled her hips back before pushing them forwards at the same slow speed, sliding the dildo in and out of Alex's ass hole again. She did this about five times, Alex grinding her teeth and digging her nails into the toilet to prevent herself from crying out in pleasure. Luckily this coincided with first the newcomer's toilet flushing, then the sound of running water and the hand dryer going off, so the other woman was probably none the wiser. Either that or she mercifully chose not to check up on the tiny sounds Alex couldn't stop fall from her lips.

When she heard the footsteps head towards the door and then that door opening and closing Haley whispered in her sister's ear, "Sorry Alex, I just couldn't help it."

Fuming with rage Alex opened her mouth to bite down on Haley's hand with the intent of giving her sister a piece of her mind, but it was a good thing she didn't go through with it because a deafening cry escaped her lips as Haley lifted her body up slightly and then began brutalising Alex's ass. There was barely any build-up, other than everything that had come before, and because Alex's back passage was loosened up from that and the constant butt fuckings Haley was now giving her Alex felt nothing but pure pleasure. So much so, she was soon having the kind of overwhelming climaxes she could only have when her big sister was fucking her up the ass.

Haley was soon interlocking her hands over Alex's mouth to try and muffle her baby sister's squeals of pleasure as she ruthlessly sodomised her in this public bathroom. It was hard enough when Alex was also trying to keep quiet, but it wasn't long before the teen was clearly too far gone, lost in the ecstasy rushing through her body. Part of Haley was proud of that, especially as her kid sister's cum began squirting out of her cunt, however if Alex started screaming any louder surely the whole place would hear, and if anyone else came in they would be totally screwed. And yet, Haley just couldn't stop butt fucking her baby sister.

Even when Haley came, the stimulator inside the harness bashing against her clit and the sheer joy of sodomising her little sister combining to give her one of the most powerful orgasms of her young life, she just couldn't stop fucking Alex's fat ass. Even if both their dates rushed in here, stood on top of the toilets in the stalls on either side of them and peered in to see Haley fucking her baby sister's big fat butt she wouldn't stop. They could take pictures, call their parents, whatever, and the entire bathroom could fill up with everybody in this building and Haley wouldn't stop pounding Alex's big glorious booty.

It was just unbearable to even think about stopping, this particular butt fuck perhaps even nastier than all the others not just because of their surroundings but because Haley found herself pulling back on Haley's head as if she was putting her into one of those submission moves the wrestlers on that wrestling show their brother sometimes watched. If nothing else Alex's back must be in agony, but Haley wanted to make sure her kid sister's butt hurt even worse when they were done. That Alex would have to shift from cheek to cheek for the rest of their double date, that her younger sibling's back hole would be gaping open all night long, and that the cute brainiac's sore butt would remind her who owned her big fat ass.

Unfortunately Haley didn't have unlimited stamina, and despite the energetic sex she had been having with her sister making her a lot more athletic inevitably she ran out of steam, her sweaty body collapsing down on the equally sweaty body of her sibling. Of course she made sure to push herself to one last climax first, Haley enjoying the after-shocks of that climax for maybe a full minute. Afterwards she snuggled against her favourite pillow in the world, so relaxed that she barely reacted to the sound of knocking. Mostly because she was too tired to register it.

Then she heard a familiar voice call out, "Are you sure you're okay in there?"

"Just one more minute." Haley squeaked, before quickly straightening up and yanking her dildo out of Alex's ass.

She then whistled at the sight of her handiwork. Alex's ass hole always looked cute, but in Haley's opinion it was at its very best when it was gaping open like it was now, the hole itself battered and sore, as were Alex's anal walls, Haley spreading the other girl's ass cheeks so she would get the best look possible at her baby sister's brutalised bowels. Haley wished she could spend all night staring into that bottomless looking pit which had become her kid sister's rectum, but they really did have to leave, so she stood up and reached for her harness. Then she had a wicked idea which made her grin evilly.

"Turn around." Haley ordered, her smart little sister correctly guessing her older sibling wanted her to stay on her knees, so Haley could have the intoxicating sight of Alex kneeling before her as she told her, "Now suck my cock."

Alex's eyes went wide and she exclaimed, "Ewww, you can't be serious?"

Haley shrugged, "I'm not going out there to try and clean it in one of the sinks, and I'm certainly not using toilet water or putting it back in my bag as is. So it has to be your mouth."

For a second Alex bit her lip and then she asked, "You can't get some paper towels or something? I mean, licking your ass is one thing, but-"

"Suck my cock clean or I'll never fuck your ass again!" Haley softly threatened.

It was an empty threat, and deep down they both knew it. Haley couldn't stand the thought of living in a world where she didn't get to indulge in her twisted lust for her baby sister's big butt, however the only one more addicted to this twisted anal incest than her was Alex, and Haley was betting that the tiniest possibility of not getting her fat ass stretched again by her big sister would pressure Alex into this latest perversion. And sure enough after a few long seconds Alex scrunched up her nose, leaned forward and wrapped her lips around the dildo which had been so recently deep inside her fat ass.
