I've had a lot of fun training you with My strap on, but I just don't think it's big enough. I think it's time we take it to the next level. I want to stretch out that asshole in ways it's never been stretched before. To start off, I have you start sucking My 9 inch strap like normal. Get it nice and wet, so I can shove it in your ass quicker. After a few minutes of sloppy sucking it's time for you to bend over.
I only fuck you for a little bit though because the point is to get your ass gaping to make the fisting process much easier. Now I have you bend over, exposing your gaping asshole. I tell you that if you can fit all 5 fingers in your ass I'll show you My big tits. Start with just two, and work your way up. Slowly start shoving your hand deeper and deeper into you ass. Soon you'll be fist deep in your own asshole.
I get up, and pull out My tits, as I encourage you to go deeper and deeper. Maybe if you practice enough you'll be able to take 3 cocks in your ass at one time! A cock sluts dream! I have you roughly fist your asshole for a bit, before I allow you to cum all over My big strap. Of course you'll have to suck it all off before I let you take your fingers out of your ass. Oh and did I mention that you're not allowed to stroke at all? Anal stimulation ONLY.
