I'm having some digestive problems so I need my slave's tongue to lube my asshole and help loosen me up so I can take a really big dump!! I sit backwards on the toilet and my slave must keep his face deep in my ass crack, licking and cleaning so that I can pass these logs smoothly when he's done. I also push out lots of deep, pungent farts as the clip goes. I think my slave's licking helped let out a bunch of pent up gas. It's incredibly foul and stinky because the dump is getting closer to coming out. At the end, I sit front-on and put the slave's face between my legs to take in the whole aroma of me releasing my waste.
