Epilogue: The Lion Cub

Robb thrust a last time, silencing her moans with a kiss. Fucking a wildling girl had special appeal, and he always sought out Gilly when he was in the mood for a wild, uninhibited and rough fuck. She was good. With a groan, he released his semen in her snatch.
He rolled of her, but pulled her towards him to cuddle her. She was just adorable, he couldn't help it. After a while, he noticed she had fallen asleep. He got up, put another blanket over Gilly and left the room. It was late already, the only sounds came from the storm outside. Robb enjoyed being alone from time to time, so he wandered around the castle for a while before he went to the Lord's chambers. He expected his wife to sleep, but was surprised by her sitting upright in their bed, naked, and passionately kissing his sister Sansa.

Aroused, he closed the door behind him and watched the two girls fondling each other's breasts. He could almost feel their passion, they were clearly lusting after each other. Sansa had had some sexual experiences with Margaery before, but Robb would never have expected her to initiate anything - and Myrcella was completely ingenuous in regards to other girls. "What do we have here?", he finally asked.
They both jumped, let go of each other and looked at him with horror on their faces. "R-Robb...", Myrcella stammered.
"Robb...", Sansa said, "I'm sorry... it was me... it just overcame me... She's so pretty, I wanted..."
Robb raised his eyebrows and smirked. "I didn't say you should stop."
They both looked at him with open mouths. "You- you don't have a problem with it?", Sansa asked.
"I'm loving it. Might as well make my last night in Winterfell memorable. How about you two lick each other, whoever comes first gets rammed in the ass."
They both looked shocked, then quickly got to work. Sansa lay on the bed, let Myrcella sit on her face and started licking her cunt. Quickly, the blonde girl leaned forward and placed her head between Sansa's spread legs to give her the same treatment. It wasn't long before Myrcella cried out, let go of Sansa's cunt and twitched heavily while drenching the Nothern girl's face in her sweet nectar. "I win", Sansa said, licking her lips and rolling the Lannister bastard off her. Robb was already naked and hard and wasted no time getting in position. His sister flipped Myrcella around and lifted her up on all fours, then spread her butt-cheeks. The Young Wolf grabbed his cock and entered the girl's ass, earning a lustful scream. Robb kissed his sister.
"Sansa, you will have to look after Winterfell while I'm gone."
The raven had arrived today, summoning the armies of Westeros to the North. The White Walkers were moving, and the Long Night was upon them.
"Come back to me, brother", Sansa said while Robb was ramming his wife in the butt. Robb made another thrust and smiled. "I will."
