If you're dead set against it--and that's your right--you should just be up-front and say that that is something you do not wish to do. By suggesting that you would let him do it to you if you could peg him, you opened the door to the possibility of having it done. Trying to let someone down easy almost never works.

I'm so honored to be in the OPs name, I forgot to take offense at the content of the story. I realized, no, realised, wait... I've been bent over for an hour and instill haven't felt anything. Is it in yet? How does a woman handle that question?

Sounds fair to me.

You should tell Perdi- I mean your boyfriend that it was just a joke, and not a dick, so don't take so straight... Wait, wait, scratch all that.

eww!

Man, when a guy asked me for anal and i came back with that same response, none of them said yeah...dang, you better take him up on his offer and peg him please. Lol

Wait, before you do this, I need to start recording... Oh and can we get Doc in on this?

Is honesty and being up front not cool nowadays? geez.

Hey, getting pegged is awesome! :-)

Doc will only be there at the end when something's stuck. Maybe that'll be his new profile picture!
