Well... she was bent over already

"Oi Bran!" The girl whispered loudly, but not enough to give away their location.

"A-aye?" She heard him respond with a slightly startled tone.

"Fuck me." She simply ordered him.

"What?" Her ears listened to him reply incredulously. Arya turned her head and saw her brother holding an anxious expression, it reminded her of when they were little children and mother would catch him climbing the broken tower. "Right now? What if mother and father..."

She would've found the whole situation amusing, if not endearing. She loved to make her little brother confused. But the deep carnal desire she felt for what he kept inside his trousers didn't leave the rebellious young lady with much patience.

"Just shut up and stick your dick inside me already." The Stark girl told him whilst pushing her rear against his crotch, almost as if just throwing it at him for him to handle.

For a moment, she believed he would be to scared to go trough with it, but when she felt his strong hands enveloping around her slim waist, Arya half-smiled. Her heart started beating faster at the prospect of being penetrated by her brother for the second time ever in her life. This time just as risky, if not riskier, as the last time that they were together. It was a good thing that boys were so easy manipulated by girls. She was glad she was no exception to the rule, despite exploring the aspects of her sex more thoroughly only recently.

Whilst watching her mother moaning so lustfully as her father went in and out of her, as well as awaiting for Bran to do the same, Arya could tell she was getting wetter and wetter. Finally she felt a breeze go up her legs as she imagined her sibling lifting the skirt of her dress. The Northern lady could barely hold in anticipation when then...

"Ungh!" She quietly exclaimed when she felt him inside her.

Arya had barely sensed his tip against her entrance before his whole shaft penetrated her, making her knees falter in response. She had to admit that she was not prepared for that. But feeling every inch of his manhood stretch her was nothing if not divine. Though of course, she would hardly want it to stop there.

The young lady, likely unable to speak if not in primal grunts or moans, nodded as if to signal her sibling to keep going.

Bran obeyed.

Arya felt her younger brother's cock slide out only to slam against her behind and then slide out again and push against her walls once more, and then again and again in a cycle of never ending lustful pleasure and desire. The Stark bit her lip in an attempt to keep themselves hidden. If their parents discovered them...

The thought sent a shiver up her spine, almost making her come.

Her Bran fucked her in a slow though steady and fierce rhythm, as if aware that she wouldn't be able to contain herself if he were to go faster. Arya submitted to his pace, moving her hips along his. She moved and lifted her little ass in ways she hadn't thought she was able to.

Bent over against a tree whilst her younger sibling kept shagging her from behind, Arya watched her father do the same to her mother. Perhaps it was not so ironic that both her and Lady Catelyn were getting their cunts fucked in the same way. The seemingly mirrored version of their parents that both her and Bran constituted given their appearance was sure interesting. With Arya representing a version of her father that had tits and wore dresses instead of being lord and her brother representing a version of her mother that had been born with a cock and a pair of balls between her legs instead.

Despite the curious observation, the girl was too focused as she braced for Bran to thrust his manhood deep inside her again to dwell on it.

She felt Bran bend over a little bit himself, searching for her petite bosom constricted by her dress. She smirked at his clumsiness and felt some joy when his hand had finally managed to find and cup one of her breasts.

The Stark liked the wild and inexperienced way she had sex with her brother. The fact that both siblings were still discovering each other's bodies and how they worked meant that there was something primal and genuine when they made love which made Arya incredibly aroused. Though she supposed they would have plenty more opportunities to get familiar with these acts of profanity once they started their journey on the Kingsroad.

As indicated by the increasing tingling between her legs, such thought made the Stark lady even more excited.

The young noblewoman turned her attention back to her mother. She watched Father sloppily kiss her neck as if burying his face on it like one of those unwashed wildlings, making the ageing woman moan and giggle. Arya bit her lip in order to control a giggle herself. No way Sansa would be willing to have this sort of fun. Her sister would sooner join the sept.

See stupid Sansa? The girl said inside her head, as if able to communicate with her boring redheaded older sibling through her thoughts. You've always kept telling me that I couldn't be your sister. But it seems I'm much more like mother than y-

Arya bit her lip hard as the thought provoked an unexpected reaction, a rush she felt coming down her core that she was quite familiar with. The girl held herself tighter on the tree as she sensed her knees grow weak. She barely realized Bran's manhood growing tighter inside her before a shiver ran down her spine. Finally, Arya came like she never had before. Her lovejuices creating a wet and sticky mess between her legs.
