Robb does them both doggystyle
From Create Your Own Story
Gripping Sansa's ass, Robb slowly penetrated her. She moaned as he got deeper, eventually hitting her hymen. Pulling back, he thrust through it, breaking it. Sansa cried out in pain, but was silenced by Arya's lips. Robb began moving in and out, and his sister's pan became pleasure. On all fours, she began thrusting back at Robb, meeting his thrusts with hers.
Arya, aroused by the sight of her sister being fucked, crawled to the right of Sansa and got on all fours herself, presenting her ass to Robb. Her butt wasn't as full as Sansa's, but it was sexy in it's own cute way.
"I think it's my turn," Arya said sexily, wiggling her ass. Robb smiled and pulled out of Sansa, earning a wimper from her.
"Don't worry," Robb assured, lining up behind Arya, "I won't forget about you." He then slammed into Arya, getting most of his cock in. She screamed in pleasure and pain as he got balls deep by the second thrust. He fucked his little sister with no abandon. Arya moaned, turning her head to the side and kissing her sister. Her whole body was rocked by Robb, who, using his free hand, had begun pleasuring Sansa. He thrust into Arya harder and faster and soon she reaches her climax.
Arya grunts as she cums. Her ellbows give in, she collapses forwards onto the bed, quivers, slams her legs together and squirts all over Robb's dick.
Pulling his dick out, he returns to Sansa, penetrating her pussy once again. Sansa moans as Robb fuck her with a ferocity he didn't know he had, determined to make her cum before he did. She screams into a pillow as Robb shoves his entire length into her over and over again. His right hand began to stroke Arya's quivering pussy, eliciting moans from her. Arya, still hungry for her sister, shifts her body under Sansa and begins sucking on her swaying breasts.
The extra stimulation is too much for Sansa. She climaxes, screaming her brother's name as she covers his dick with her juices. He climax with her, filling her unprotected womb with his sperm. He doesn't care about the risk of pregnancy, he just wants to fill his sister to the brim. Load after load pours into the redhead, some even leaking out, leaving Robb feeling completely drained.
He pulled out and collapsed onto the bed next to his sisters. Equally tired, the Stark girls cuddled up on either side of him, Arya to his right and Sansa to his left. They just layed their, panting heavily, for a few moments. Then Sansa turned her head toward him to give him a look of pure, unadulterated love. He smiled and kissed her.
"I love you," Robb whispered, still gasping for air, "Both of you."
"I love you too," Sansa replied, before kissing him again.
"Same here," Arya added, cuddling next to him. The three of them fell asleep like that, drifting into a dreamless, blissful sleep.
Are they found by anyone?
