Get on your knees on the sofa, facing away from the camera. Your asshole should be pointed directly at the camera.
Now reach back and pull the string of your panties out of your ass crack. Hold it to the side and spread open your ass cheek. Let's get your exposed asshole on film.
As you keep your ass spread, look back into the camera with a suggestive smirk so that the viewer thinks that you are opening your ass for them. Of course, we all know that you would like nothing more for those that are watching this film to have their way with your ass. Nothing gets you off more than to have your ass stuffed by cocks, dildos, fingers or any other object that can find its way inside of you.
