You get .

You wake up and find yourself naked, bound and gagged in your sister's room. Your arms and legs are tied to the bedposts leaving you in a very **** position.

Arya comes out of her bathroom. She was wearing a plain grey shirt and her special underwear which showed off her burgeoning bulge. She jumps and lands on your crotch. You let out a grunt in pain.

"Hey, Da. Are you comfy?"

"Mmpph..MMMggghh..."

"Oops, my bad! Here, let me..." she removes your gag. "There we go."

"Arya...this is not you...stop this please!"

"We've been through this Da. You're starting to sound like a broken record."

"But.."

"I'm gonna stop you right there. I'll give you two choices. I'm going to **** you now. However, you get to decide whether I put my fat dick inside your ass, or would you rather have me take you in my pussy."

"Why are you doing this?"

"Because I don't want to share you. I've come to realize that you belong to me. Not some gigantic whore. Me! "

"You don't have to **** me, Arya. There will be no coming back from this..."

"Oh, I don't want to come back. I just want to come in you. I will break you before this week is done. And all you'll ever want is me, ONLY ME! Now...I'm gonna ask you again. Ass or pussy? "

Maybe if you gave in you could try to reason with her...once she's done using your body.
