Getting into position for anal

Kim stands up and gets into the doggy style position on the sofa. I step behind her, and lift her skirt up and put it on top of her ass. She is only wearing the tiniest of g-strings under it, and as I spread Kim's ass cheeks I can see her inviting asshole underneath the string.

Kim flinches a bit as I spread her ass cheeks, and I see her asshole squeezing as she flinches.

I look to my side, and I see Kim's mom standing there filming it all, with a big, greedy smile on her face. She sees me looking at her, so smiles and nods, signalling for me to go ahead.

I spit a bit on my fingers to lubricate my cock, and as I am doing that I can see that Kim has picked up her phone and is busy texting, or maybe taking a selfie.

I position myself behind her world famous ass, and start pushing my cock against Kim Kardashian's sphincter.
