First, you click the
search button and do a search for "strapon". Then you
look at all the results where we've actually discussed this a lot. Like in
this thread or
this thread.
Then you figure out why you can't have this conversation with her if you're already fucking her in the ass. Obviously you don't have a problem discussing doing her, so why is it a problem to discuss her returning the favor? That, to me, seems to be the big problem here.
