These femdoms need to make sure that their human toilet is getting every last bit of their delicious shit into his wide open mouth. The best they have for doing this is to place a plastic tube over his entire face and squat over it as they unleash torrent and torrent of their wet and smelly shit inside. The tube keeps everything neatly on his face so he has no option but to eat his way out.
This human toilet is going to eat the piss and shit from two women today. First Mistress Gaia is going to squat over his mouth and let her pis flow free. Then, her friend is going to take her turn by getting her asshole right up to his mouth and letting all the shit she has stored up slide out of her asshole and land right on his lips for him to eat.
Lady Celine never uses a bathroom because she has a perfectly good human toilet right in her living room who is always ready to eat her tasty shit. She places him right below her comfortable toilet seat and spreads her ass cheeks wide before letting her wet, smelly shit slide out of her tight asshole and plop right into his waiting mouth. Then she gives him some piss to wash it down.
