She notices him staring her chest

Arya saw her brother hungrily stare at her in a way she'd never seen before. She had fantasized about him for some time, but only now she could contemplate his figure properly. He was a bit slender, but his shoulders were broad enough. She didn't know his face was that beautiful up close. The Stark was suddenly conscious of her own body too. She had always been insecure about it, having considered to have the bare minimum to come across as a girl. Why couldn't she look more like her sister?

"I never did touch your breasts actually." Her eyes shot up at his sentence.

"You want to fondle my tits?" She asked surprised. What a waste of his time. She thought.

"When you put it that way..." He began.

"Just have at them." Arya cut him off, pressing her breasts together as to look a bit more desirable. "I'm not making any promises though."

She had perfected the art of not sounding insecure. But acting out her female side was still a relatively new concept to her.

She sensed her brother groping her, every little area of her bust being felt by him. His touch felt good and the massage he gave her breasts sent tingles between her legs.

The girl bit her lip in response to the feelings running wildly inside her.

She was suddenly turned around by her brother. The cleavage of her dress was savagely pulled down. The air against her exposed buds made her yelp.

"Stop! You'll ruin my dreaahhh..." An involuntary moan cut her off before she could protest. All sorts of things were being done to the highborn's nipples, each one more pleasant than the last. Pulling, pinching, twisting. She shifted a bit of her weight, her butt trying to feel his bulge.

She saw Bran bring her closer to a chair. Arya was then lifted and placed on his lap. Other parts of her body received his attention, her breasts never being left alone. Her neck was kissed, her hair was twirled and faint humps teased her bottom to the point of insanity. She could've sworn her sex twitched when he caressed her thighs. But the girl couldn't bring herself to ask something so lusty.
