You're done when i say so

I know you love my strap-on. I tease it out from under my skirt. You can admire my bum as the skirt rides up, and you can admire my big purple cock. But, that's about all you're going to see - because this is going right up your tight little arse. I know exactly how deep to push this into you to get the best result. I talk you through what I will do to you, and get off on your humiliation. I release my boobs, so they can wobble free - you won't get to see them, you'll be face down looking at the floor. Now, I love fucking. So, you're going to turn around, present your arsehole - and I'm going to keep going until I'm done. You're done when I say so.....
