Roll Them Bones
Time for another break! Aren't I a sweetheart.
Hands off your dick. Lube up your toy, whatever it is you have to fuck your ass. Time to turn that little hole into a tunnel. When it's nice and slick, go ahead and slide it in. Easy now. Don't rip yourself open!
All right, but I don't have all day, get it the fuck in! Now roll them bones!
That's right. You're going to pump it in and out whatever number you roll this time. Don't touch your dick, just fuck your asshole.
Oooh yeah, you're my little anal slut, aren't you. You're just dreaming of me taking you from behind with my big black strap-on, fucking you deeper and harder, burying every inch inside you, until you pass out.
When you've fucked yourself good and hard as many times as you were supposed to, you may take it out and continue.
