Her womb gets flooded with his seed

Arya felt her brother moving strangely, his manhood twitching within her. A liquid warmth spread throughout her insides. Is that his cum? The girl thought with her bare arse still up. His seed made its way to her core, flooding her womb with it. Her brother finally managed to pull out, leaving her hole with his cock's shape and some cum on her cheeks.

Arya hadn't any strength left. Drained, the girl fell limply on her side, the liquid still warm inside of her. She tried controlling her emotions, denying herself how scared she was.

"I-I didn't mean to..." She heard him start.

"U-umm... it's a-alright really, I'll just wash it out." She reassured him. The last thing she wanted was to scare her brother into never doing it with her again.

"Do you need any help?" What? Gods no, Bran. She said inside her head.

"No, no thanks. I s-said it's alright." The girl slowly pulled her skirt down, covering her naked bottom. She was still a little wobbly and her legs were tired from holding her ass up. Arya smiled as his brother kindly helped her get on her feet. He was as honourable as their father. She decided to reward him with a peck on his cheek. The girl quickly left him at his chamber's doors, her face blushing wildly and holding a giant grin.

As she neared her and her sister's room, the Stark halted for a moment. She lifted her skirt to see the feminity between her legs. The moon light showed Bran's and a bit of her own juices were leaking out, her pussy glistening with it.

Arya stuck her hand there to grab some of the manly substance that had filled her womb. She held it in front of her, analyzing the white and viscous liquid. The girl sucked it off of her dainty finger, getting Bran's cum on her tongue. She smiled, what she'd predicted earlier was already happening. She did enjoy having his taste on her mouth.
