You beg him to stop

"Please that's enough" you cry. The tears are running down your face "please you are my brother."

"You see?" says your father "she's starting to understand her place. Of course we can't stop there, because she's trying to appeal to your emotions."

Jack hesitates for a moment but then you see his cruel smile, he hits you few more times.

"I'm sorry, I'm sorry, please stop."

"You see?" says your father "she finally recognizes that this situation is her fault. That's a very good sign, she's starting to recognize her new place in this household. Now let's see if she's ready for something more than words. Take off your pants."

Jack hesitates for a moment, but a stern look from your father is enough to make him to do it. He's already hard, he's even bigger pervert that you thought if hurting you made him so excited. At least you know that you can make him cum quickly.

"Slap her face with your dick."

It not hurts, but it is in some way more humiliating than being hit by hand. You have to endure it, you'll tell mom everything and then they will be fucked.

"Slut, open your mouth. Oh, right, you need to remember about that Jack" says father "never refer to her by her name. She's a slut. not Emily."

You are getting angrier and angrier, but you control yourself, Jack will probably cum in like few seconds.

"Shove it in" your dad orders him.

Jack obey and although he cums almost immediately, you were close to choking on his cock. It's big and you weren't prepared for his cum. That's disgusting!

"Swallow it" says your dad.

You don't want to, but you know what will probably happen if you spit it out, so you force yourself to eat your brother's disgusting cum.

"We'll have to work on your stamina" says your dad to him "now leave us. I have something to say to your sister."
