Show mercy

Jon halted his advance and started speaking "Aw my sweet sweet little sister. If you only knew how good you make me feel right now. Thank you so much for letting me do this with your sexy arse. But I can tell you are not feeling the same as me. Do you want us to stop?"

Arya lifted her head up from the bed and wiped her face using her arm before turning around and looking up at Jon with teary eyes. She hated being given this choice, but she loved him for it. He was always caring about her, even now when he was enjoying himself.

With a whimpering voice she replied "No Jon I want this, even it it hurts. I don't want to stop, I want to make you feel good even if I don't. Isn't that a woman's duty, to please her man? So please Jon do it, fuck my ass and cum inside me!"

This brought so much joy to Jon, he could now enjoy his sweet little sisters ass without remorse. He knew she wanted it and he would not disappoint. He would fill her ass with cum that was for sure.

"Oh thank you little one! I was worried you would deny me that sweet relief. Of course I will cum in your ass, you need not worry about that. Please just try and relax and it will be over soon."

Arya made a strained smile before turning her head away from him. Taking a deep breath as she knew she would soon burry her face again. Despite the pain, she was feeling happy. Now she would be a proper woman and Jon would have to treat her as one in all regards.

She felt his hands take a firm grip on her hips and she knew he would start pushing inside her again. Jon started very slowly, making it as easy has he could for her. She whimpered and gasped as he got deeper inside. But she did not yet scream or cover her head and still held herself up in her hands.

It was incredibly sexy seeing his little sister struggle so hard for him. Doing her best to show a strong front and not letting her sobbing spill out. She didn't succeed completely thou and from time to time she let out a moan of pain "Aaahoow ah ah...". Jon stoped moving to let her pull herself together and she always did. Then Jon continued his quest to see just how much he could get inside before she couldn't take it anymore.

Arya fell down to her arms and shouted out "Oooh Jon... How much is there left of you cock! It feels like it goes on forever in my butt."

Jon pulled her ass cheeks apart to get a better look "I'm sorry little one but you are just about half way there."

"ONLY HALF?!" She shouted at full force before continuing "Jon I know I promised to make you cum using my bum. But I'm not sure I can take it all this time, I'm sorry."

Jon was thinking, there wasn't much she could do to stop him from forcing it all the wsy in, but was that the right thing to do?
