Slave Gets His Mouth Fucked With Scat Strapon

Grinning smugly, Lady Claire tells her slave Ciphers that today is the next step in his education as a human toilet. She sees fear and disgust in his eyes. But that only spurs her on all the more to train him to use the toilet.
She pees with relish into a bowl and forces her slave to inhale the scent and taste it. He has to lick it off his fingers, which she pushes even deeper down his throat.
She then makes herself comfortable again and shits in the bowl. She then presses the slave's face firmly into the bowl with the disgusting mixture to condition him so that he only wants to eat and drink it in future.
But that's not enough for her education. She puts on her strapon, smears it liberally with piss and shit and forces the slave to suck it, lick it and take it down his throat. His whole mouth is to be smeared with it by the strapon and the mistress's fingers. Ciphers chokes and moans, but Lady Claire knows no mercy in her upbringing.
