"Tell them to leave." Arya whispered in her sister's ear.
Sansa blushed, and then tried to protest weakly, "Arya, I just have one more meeting and then it's lunch. Can't we-"
"No!" Arya shut her down, "Do it now."
Sansa gulped softly, took a calming breath and then announced, "Everyone, can I have your attention please. We're breaking for lunch now so I can have a private discussion with my sister about the North's future. So everyone out. And I mean everyone."
There were murmurings of disapproval and then one of the Lords tried to protest, "My Lady-"
"Now!" Sansa told him sternly.
"Yes my Lady." He replied, he and the rest of the Lord slowly making their way out of the room and closing the doors behind them.
"You two." Sansa sternly told the guards, unnecessarily explaining, "We wish to be alone."
"But stand outside the door and make sure nobody enters." Arya added.
Again the room echoed with, "Yes my Lady."
Once they were gone too Arya ordered, "Get out of my chair."
"Yes my Lady." Sansa blushed, her previous boldness forgotten as she rushed to do as she was told.
Arya smirked, slowly sat down on HER throne, looked her sister up and down and then ordered, "Remove your clothes. All of them."
"Yes my Lady." Sansa again blushed and quickly did as she was told.
Arya paused briefly for a few long seconds to admire her sister's body, even as she shivered in the poorly insulated Great Hall, and then ordered, "Come here."
"Yes my Lady." Sansa smiled shyly, truly liking this command.
Sansa then quickly close the distance between them, causing Arya to smirk as she sat on her lap and kissed her. Being so much bigger Sansa really had to bend down to kiss her sister almost regardless of the situation, although this angle was particularly difficult.
On the plus side, the chair was designed for someone much bigger than tiny little Arya Stark that it was easy for Sansa to fit her knees and the lower part of her legs either side of her. In fact most chairs were, so this was practically routine for them at this point, and simply put it was Sansa sitting in the lap of her warrior woman and showing Arya her love. Although she had no doubt more would be required.
Proving her sibling right Arya slowly undid her top, pushed it aside to reveal her tits and then broke the kiss and ordered simply, "Suck."
"Yes my Lady." Sansa murmured softly with another little smile, before doing as she was told.
This really put a strain on Sansa's neck and back, but it was worth it to hear Arya crying out softly with pleasure. Also Arya's tits were much, much bigger than Sansa's, almost comically so considering the girls size, and while Sansa would have never of guess that she'd be like one of those lecherous men craving big boobs she found once she was gifted with a pair she really enjoyed them.
Of course Margaery Tyrell had been her first woman, and she had truly, deeply loved her, so she spent a lot of time lusting over women with similar bodies, like even that bitch Myranda Royce. Thankfully nothing had happened with Myranda, or any other woman, so her second ever woman could be her sexy and ridiculously skilled sister Arya, who had the greatest tits Sansa had ever seen.
As much as she had adored Margaery's breasts they just couldn't measure up, and had been at least part of the reason Sansa had found it impossible to refuse Arya.
That, and her little sister was a force of nature which she found impossible to denie, which was proving by exactly what they were doing now, Arya even gasping, moaning and whimpering much louder than she should have given their current location, and yet Sansa allowed her to get away with it because she just couldn't get enough of these tits.
Or everything else that Arya eagerly gave to her. Now though, Sansa was very much focusing her attention on these big boobs, going back and forth between them and giving them the attention they deserved.
Which included swirling her tongue around each nipple, sucking on them, and even biting them. It wasn't a surprise that Arya would like that last one, but it did surprise Sansa just how hard her sister insisted on being bitten. Sometimes Sansa would even draw blood, and Arya would only seem to love it even more, but thankfully this was not one of these times, and Arya was content with Sansa mostly just sucking her big tits with increasing force for several long minutes.
Then Arya reached down, undid her trousers and awkwardly pushed them down around her ankles, meaning that she had to lift them both up momentarily, which the tiny girl did with ease. That effortless display of strength was almost as big a turn on as what Sansa would be suspected to do next.
"Eat me." Arya growled.
"Yes my Lady." Sansa once again replied.
Arya had never liked being called that. In fact she had loathed it. She wasn't a Lady. She was a fighter. A warrior. And now, an assassin. But this was different. This was Sansa Stark, The Lady Of Winterfell, addressing her subserviently to solidify the roles of top and bottom within their new sexual relationship.
Even implying that despite whatever other people might think, it was the younger Stark sister that was The True Lady Of Winterfell, and Sansa was just a pretender that Arya allowed to sit in her seat. Like a child playing pretend on their parent's throne, much to the amusement of that parent. And the truth wasn't far off. So yes, Arya would both accept and enjoy hearing that particular title from her sister's lips, at least in private.
Of course it was far from Arya's favourite thing that Sansa did with her lips, the brunette thought with a smirk as the redhead got down on her knees in front of her, in front of the throne, and then with doe-like eyes lowered her face in between Arya's parted thighs. Arya parted these thighs even more as Sansa approached, and did her best to remain silent as her big sister's tongue pressed against the bottom of her pussy and then slowly slid it all way up to the top.
Arya had been trained to be silent when she had to be, and her teachers would probably be very disappointed in the high-pitched sound she made as Sansa began to lick her pussy. They would be even more disappointed as she continued making those sounds, and got louder when she gave Sansa permission to increase her attentions.
"More! Lick me more, harder, ah fuck!" Arya moaned, "Yesssssss, more, more, more, ah fuck! Yes sister, use your tongue! Use your tongue just like that! Oh shit!"
To be fair this wasn't really a problem, as by now the Lords would have likely been halfway to the kitchens by now, and there probably wasn't a guard on rotation that was allowed anywhere near them which hadn't heard them fuck at this point. However it seemed prudent release trying to pretend she wasn't having sex with her sister, or at least try and hide how often they did it, and for how long.
Perhaps even part of Arya would have liked to be able to fuck in complete privacy, away from prying eyes. Sadly that wasn't possible for girls in their position, although at least they were too scary in their own way to questioned. No, they were left alone to their debauchery, something which Arya very much planned on enjoying this lunchbreak.
