You pull up Anna nightgown and pull her panties off. "Elsa, what are you doing?" Anna asks. "Shut up Anna." You look at your sisters naked bottom and you wonder where you would stick your dick in.

Which hole do you put your dick in?

Her tight virgin pussy.

Her super tight asshole.

First gag her so she doesn't scream
