Sansa points something out

From Create Your Own Story

"I-It's not fair!" sniffled Sansa. "I got it on my bare bum, but Arya's going to have her smallclothes to cushion her!"

"That's because you're a stupid slut who doesn't wear any!" snapped Arya.

"Girls, girls!" said their lord father angrily. "This is exactly why..." He gave a frustrated growl. "Arya, lower your smallclothes. You deserve this no less than Sansa."

Arya considered protesting, but nodded, and lowered her smallclothes around her legs. Her father's hand landed with a sharp slap on her rear. "Ow!" she cried.

"Who's stupid now?" said Sansa with a smirk.

"Sansa!" snapped her father, giving her another paddle on the rear. She screamed from the unexpected contact, his hand leaving a mark on her ass. "If you girls cannot learn to behave as sisters, then you will be punished as sisters!" He gave Arya another slap on the rear, alternating between the sisters for awhile. Arya closed her eyes and tried to ignore the sting. She thought of riding with Jon and swordfighting with Bran. However, each spank brought her out of her daydreams.

Eddard's hands came down hard on his daughters' haunches, the sound of the slaps echoing in the godswood. The sisters groaned and grunted as he struck their shapely rears. Oddly, it seemed to Arya that the pain lessened as the spanking continued, her father's blows becoming lighter, and yet seeming to linger longer.

"Have you learned not to be naughty?" muttered her lord father, his voice heavy and thick. "Will you be good girls now?"

"Unngh," groaned Sansa. "Yes. Ss-Sorry... father..."

"Sorry," Arya whimpered.

"That... that's better," muttered Eddard. "Now... lower your skirts, and... let us go."

Arya and Sansa backed away from the tree, turning as they did so. As she lowered her dress over her aching rear, Arya heard her sister gasp. Sansa was staring wide-eyed at their father, and it didn't take Arya long to figure out what had caught her attention. Eddard's manhood was straining against the seams of his breeches, heavy and hard. Arya joined her sister in staring at in fascination. As she watched, Sansa licked her lips...
