While a certain amount of patience had been figuratively and literally beaten into her both by her unofficial and official teachers Arya still struggled with it, partly because she was alone, and partly because she had waited long enough to get the things she wanted. That was one of the best things about fucking Sansa. Whenever she truly wanted something, it would be hers.
All she had to do was say the words. And sometimes not even that, as Sansa continued to show such wonderful initiative, like beginning to tease her entrance with her tongue and wrapping her mouth around her clit and gently sucking on it, particularly the latter almost making her cum on it's own.
Luckily while close it was never quite enough, which was enough to make Arya wonder if it was intentional or not. She'd been with plenty of girls who did it as a happy accident, or because they knew or correctly guessed what they'd liked to be done to them, but if she had to put money on it Arya would guess it would have something to do with Margaery Tyrell.
She could have never imagined herself being envious of a dead woman, especially after everything she had seen, but Margaery Tyrell had been the first to taste Sansa's cunt. The first pussy Sansa had tasted. Been fingered by. Kissed. To just be Sansa's first woman. Those were honours which should have been Arya's by right, and now she'd never have revenge on her. Oh well, at least she was now receiving the benefits.
So much benefit that inevitably Arya cried out, "Ooooooooh Sansa, that's a good girl! Mmmmm, such a good girl. Lick me just like that, just like that, ohhhhhhhh fuck! Now fuck me, oh Gods, fuck my cunt! Tongue fuck me and make me cum you little bitch! Oh yes, oooooooooohhhhhhhhhh yeeeeeeessssssssss, eat me! Eat my fucking cunt! Oh Sansa, sister ,aaaaaahhhhhhh fuckkkkkkkkkk!"
Probably because they were more in a public place than she genuinely wanted to please, albeit not by much, Sansa shoved her tongue into Arya's pussy pretty much the first chance she got. Arya was just about able to stop herself from cumming right away so she could enjoy the sensation of having her big sister's tongue inside her, but it wasn't that long before she went crashing over the edge of a wonderfully powerful climax.
Which was of course followed by another and another and another as Sansa obediently continued tongue fucking her like the well-trained pussy pleaser she was. Oh yes, Arya was very much receiving the benefit of Margaery Tyrell training Sansa to be the rug muncher she was always meant to be.
Sansa certainly learn to love the taste of girl cum from Margaery, but she had no doubt that she would have loved Arya's cum even without that training. She would probably love any girl cum, as she was a sexual deviant, however Margaery had been her first woman, and of course Arya was her sister, meaning that she had more reason than most to love the taste.
Of course at that moment she was focused on just why she loved the taste of her little sister's cum so much, or perhaps girl cum in general for that matter. Or even Margaery Tyrell. No, Sansa was completely focused on swallowing as much as of that precious liquid as she could.
Thanks to her previous training she was able to pull her tongue out of Arya's cunt and seal her mouth around it fast enough to swallow every precious drop of that first orgasm. She wasn't so lucky with the following orgasms, partly because there seemed to be more liquid to swallow, but mostly because Arya tightened the loose grip she had on the back of her head before she shoved Sansa's face as deep into her pussy as it would go.
Shortly after that she began grinding against her face, and it was all over. Sansa knew from previous experience that all she could do was let the other woman use her face as a fuck pad. Which of course was something Arya particularly liked doing.
On the bright side all Sansa had to do was keep her mouth open and Arya's cum would be squirted directly down her throat and into her belly were it belonged. Not all of it, but still a good amount. And there was definitely something to be said for the feeling of her face being rubbed against an orgasming cunt.
Mostly that it felt like Arya was officially marking her with her cum as her personal pussy pleaser, which greatly excited Sansa, as she desired that title more than any other. Most importantly of all, she was pleasing Arya, and that was what was important here. In the name of that she sacrificed being able to swallow some cum in favour of just constantly sticking out her tongue so Arya could bash her clit against it.
While both Stark sisters would no doubt love to do this forever they certainly didn't have the stamina, and more to the point they didn't have the time. The Lords Of The North may return at any time, and selfishly Sansa was hoping for some attention for her needy fuck holes. Although she had her suspicions which Arya would choose to play with, given their lack of time, and the fact that Arya hadn't left it alone, not once, since they started having sex.
Sure enough the suspicion was confirmed, after Arya had given her a passionate kiss which had both sisters moaning happily as the younger one dominated the older one's lips and tongue with her own. Arya even took the time to lick Sansa's face a little, making them both giggle like little girls.
Then proving she wanted to do something very grown-up Arya ordered, "Bend over!"
"Yes my Lady." Sansa whimpered, turning around and bending over the table in front of her.
Arya licked her lips. Sure there was nothing in the Seven Kingdoms which could be more beautiful, or fuck-able, than the arse of Sansa Stark. She would happily die for that arse. Kill for it. Go to war over it. It was the greatest prize in the Seven Kingdoms, and it was hers. Hers to use however she wished, and both Stark sisters knew exactly what the other one wanted right now.
Proving that true Arya stood up, retrieved her harness from one of the places she'd otherwise have a knife, attached it to herself and then sat back down on the throne, all while staring at that magnificent prize. Gods, Arya just wanted to take it right then, shove every inch into Sansa's shit hole in one hard thrust. But no, she couldn't be that cruel to her sister. First Sansa's arse hole needed to be prepared, and Arya knew just how to do it.
"Spread your cheeks." Arya ordered.
"Yes my Lady." Sansa replied softly, reaching back and slowly pulling those arse cheeks of hers as wide apart as possible.
This time Arya smirked, before leaning forward and spitting on to her target. It landed higher than she meant it too, but then she got the pleasure of watching it sliding down Sansa's arse crack before she leaned forward and rubbed it into her big sister's bum hole with her tongue.
Arya repeated this process a few times before leaning forward even further so instead of just licking up and down she could easily swirl her tongue around it, and even force her tongue inside it. While it wasn't a surprise Arya was able to slide the full length of her tongue into Sansa's arse and then start tongue fucking it Arya still smirked triumphantly, as it was a testament to just how relentlessly she had been sodomising Sansa over the past few weeks.
Nevertheless when she replaced her tongue with a finger moments later Sansa did let out a cry which was hardly of pure pleasure. It was enough to briefly make Arya consider stealing some butter from the kitchens or something so this kind of thing would be easier.
But no, using strictly spit seemed nastier, and it only seemed to take a short amount of time for Sansa's arse to fully relax and remember its main purpose was to be a fuck hole for her little sister. Besides, Arya had no other easy access to another liquid, and there was no way that Sansa was leaving this chamber, or she'd allow the Lords to returned to it, without her big sister receiving a thorough arse wrecking.
Actually there was another liquid available to her, one which made Arya feel stupid for not thinking of it before, and with a wicked grin she removed her index finger from Sansa's arse and slid the rest of her fingers over her big sister's pussy. After that it was only the middle finger which joined the first finger in Sansa's bum, but it was worth it to hear the loud moan it forced out of the beautiful redhead.
