Girls should show that she is willing to go great length for me.

 I like girls head down and ass up.

I also like it when they spread their assholes with their fingers as far as they can possibly get it.

That shows me that she is willing to go to great length to and rip her hole as far as humanly possible for the sake of pleasing me.

It shows both dedication to me as well as willingness to endure pain.

I do not like girls who are to stingy and protective of their hole.
