Robb uses her mouth

Now that she had learned some discipline and humility, he would finish her training to be his perfect bed ****. He untied his pants and freed his erect cock. Sansa's eyes suddenly became somewhat focused, and she actually seemed to realize what was going on. They might have **** her brains out in the brothel, but she didn't need to be smart. To Robb's surprise, she lifted her right arm and grabbed his cock. Before he could say anything, she leaned forwards and took it in her mouth. Robb smiled and grabbed her head. He stroked her beautiful red hair for a few moments, then **** her down on his manhood. He heard her gag, but she didn't fight back. What an obedient little whore...
His sister just let him do what he wanted. He **** his whole cock down her throat, she gagged and drooled and her eyes watered, but she let it all happen. Robb sighed contently as Sansa's wet, warm mouth pleasured his shaft. It didn't take long until he came. For a moment he felt the desire to cover her face in cum, but he would have plenty of opportunity - for now, he let her swallow it all. She took his load and cleaned his shaft with her tongue. When she was done, he pulled up his pants again, grabbed his sister's chin and kissed her tenderly on the forehead. "Good girl, my sweet Sansa."
She smiled at him.
