Realisation of your situation sets in

The gleefully sadistic tone your mother used when she declared you nothing but a toy scared you, even more so that she came harder than usual as she said it, but there's nothing that you can really do.

You're naked, stuck under a table with a massive cock in your mouth, and you're legally nothing more than a cocksheeth. Warm liquid gushes down your throat. You shudder in revulsion at the acrid taste bubbling up from your gullet. And also, apparently, your mother's urinal. She hums in delight as she empties herself into you again.

"Ahh, that's so good! We should have done this years ago!"

You try to mumble some weak protests around her cock, but all it gets you is an "Oh hush." And another load of thick sperm down your throat.

That's how the rest of your day is spent; stuck under the desk, alternatively chugging down babby batter or gussling piss, which your mother suplies in ample amounts thanks to the intern who keeps bringing her water.
