(Mannish voice)

Ugh! Why don't you just accept that I'm a man now? 

You had no problem with me as a tomboy, but this is apparently too far for you.

I can change my name, get a haircut, and all you see is that I still have tits and a pussy.

Well...I also have an ass.

So to prove to you I am a man I demand that you fuck me like a man.

Yes in the ass dummy. What else could I mean?

Look I saw you checking out my ass last time we met. So I got these back zipper jeans so we can get straight to it.

Just unzip enough for my asshole. Don't even think about unzipping to my pussy! That's off limits now!

Well what are you waiting for? 

There we go.

(zipper noise)

(whisper)I'm ready now.

Ah-ahhh-ahh. Oh my God. Oh shit. Keep going. 

(suck air through your teeth, wincing in pain)

Yes. Keep going. Not too rough for now. Go slow.

Mmmmh...yes. That's right. You'll make a man out of me yet.

(giggles)

Having fun? You like fucking my ass don't you? I bet you've forgotten all about my pussy.

Oh God yes...I think...I think it's time for you to cum.

I want your cum in my ass. Cum deep in my ass. 

Yes...I can feel you cumming. That's nice and warm.

(pause to catch your breath)

(zips up)

(teasing) Well do you believe me now? Or do you need to fuck my butt a few more times to be sure?
