It's a well-known fact that slaves perform better and are more focused on their Owners when they are denied orgasm, the longer the denial the more subservient and compliant the slave becomes. Sadly though, for their long-term health all that built up filth needs to be removed on occasion. Not pleasurably of course, that just won't do. Mistress Tess and Miss Cate have decided that today this slave will be milked of his filth. This is a particularly unpleasant way for the slave to be cleansed of his filth as he'll get the pleasure of the build-up, perhaps even a glimmer of hope that the Ladies will permit him a real orgasm. Clearly that won't ever be happening, and on some level the slave knows this. Normally, the Ladies would recycle the filth back into the slaves' mouth, but on this occasion, they decide that they'll just leave him lying in his filth, bound and with plenty of time to feel the frustrating effects of a ruined orgasm. The slave hates the denial, but the Ladies simply don't care, after all, this is just another pathetic, worthless slave.
