By giving Arya a "gift"

A funny idea crossed Bran's mind. Unlike the day before, he pulled out his manhood from her mouth. Arya only had time to close her eyes before she could protest. The Stark felt his seed flowing out of his cock in squirts, drenching his sister's face with the sticky substance.

"What in seven hells, Bran!" He heard her complain. The young lord didn't really care, as he leaned back in his chair relaxed. Her face looked pretty with cum all over it. The angry glare she was sending him kind of ruined it though. "Motherfucker." He smiled at her cursing.

"Sisterfucker... technically." Her mouth formed a clumsy grin at his joke.

"Clever..." She begun. "Soooo clever, aren't you? Come look at Bran the cleverest Stark in the North." He then remembered something his sibling had said earlier.

"And with the biggest cock in the North. C'mon, say it." That got a chuckle from her.

"Yes Bran, with the biggest cock in the North. But how am I to explain that I have my brother's cum all over me?"

"Uhhmm... I..." He didn't really have an aswer for that one.

"Hmph, didn't think so." Arya said while cleaning her face with the skirt of her dress, getting more of his seed on the silky fabric. "Good thing I'm not as clueless as you are."
