No, what kind of pervert would do that?

No, I can't. This is too much. I can't go down this path. No matter what I have done with other women and what I thought about them. I can't do that to my sister. Is too sick even by me.

But look at those tits, look that ass. She would look great naked and collared on her knees. All that sisterly beauty messed up with cum, piss, and spit. And someone will catch her and make her do all of this. For others who are not her brother, she is as inferior as other women.

Bullshit, she is MY sister. That MY imply possession, she should be MINE.

So, again, do I actually want to fall into this path?
