Nasty phonesex involves shit and piss with a whore. Now it is your choice if you like to just watch, listen to stories, or participate in the play games. Going to make them hurt. At the same time going to make everyone involved start to cum.
After all that is the best part of all. When we cum. Leather straps are kinky and nasty. Dig my fingers up into the cunt, pinching the piss hole. Strapped down in the chair, leather binds, completely exposed to you and me. This whore is looking for some nasty play, as shown above. Fill that pussy of hers up with piss. Flush her out with piss before I cover her in scat. Rub it all over her body. By all means defecate on her with me. After all it will be double the nasty if the two of us do it together.
In fact, you take the cunt and up to almost her tits and I will spread my scat on her tits and face. In the long run it will be easier for me to balance on her shoulders to shit all over her.
Then when we finally cum we can spread it all over her and leave her sitting strapped down in that chair until it all dries on her. Now doesn’t that sound like fun? I know it is nasty fun scat phone sex, but we have no rules. No limits. Time to be nasty.
