This takes place immediately after this line:

You pushed two fingers against her lips, cutting her off before she could finish that command, “Trust me, Mistress. Trust me, and it’ll feel so good, better than you’ve ever had. You trust me, don’t you, Mistress?”

“… ye—no!”

Mistress’ eyes opened suddenly, sharper and more alert than they had any right to be, and her head jolted up very slightly. She still wasn’t focused, not so much as she would have been if she hadn’t been exposed to your chemicals at all, but this was danger, far more than it had been when you entered unaware of her abilities. A single mistake would mean she might return to fuller consciousness.

“Mistress, please,” you reason. “There’s nothing you can feel better than what I can give you. You said yourself I’m good, didn’t you?”

She lulled back, licked her lips. But she flailed with her hand for a moment, and her fingers slowly squeezed the sheet. She hadn’t told you not to, so pensively, you take the moment to bring your touch over the lowermost part of her soft, perfect skin before you reach her gender…

Then Mistress rolls onto the floor, covering herself with the sheet, still half-tucked into the mattress. “Alice!” she cried. “Stand and do nothing.”

Instantly your body jolts. Your Mistress, the basic fact of the universe around which all other things are balanced, made a demand, and so you drag yourself to the floor. Mistress lay on it on her belly, panting, still covering herself, her hands shaking and the sheet as well. Her arced back, her pale, unblemished skin… it’s only by your sharp, creative mind that you can interpret “do nothing” as “watch me but do not interact,” and even this is torturous in ways you had never comprehended, for your very soul demands you please her, and now Mistress demands otherwise. The second of Mistress’ commands breaks into your mind – You are Mistress’ pretty and obedient maid – and it seems appropriate to act the part. A maid would fold her hands delicately and curtsy, waiting to be acknowledged, and that is precisely what you do.

After some minutes – ten or twenty, you can’t tell – Mistress’ breathing returns to normal, her cute, idealized voice audible in each early gulp of air. Your ankles ache by this point, your physical body demanding a rest from the taxing position, but it’s far less painful than what you put Mistress through.

Finally Mistress turns over, her bare chest exposing itself as the sheet falls. Her eyes are as sharp as any you’ve ever seen.

“I know what you’re doing, Alice!”

She gets up, weakly at first, waving her arms for balance. Instinctively you move to help her, or rather try, but the new command…

“What was that new command I gave you before…?”

She meant it rhetorically, but you mouth “Alice Smith can never, ever attempt to enslave Jessica Parz.”

“It clearly wasn’t enough!” she snaps. She moves a warm, smooth hand to your chest and pushes you to the bed, where you bounce twice in Mistress’ juices. “You tricked your way out of the earlier ones. How do I know you won’t trick your way out of these?”

“I’m your slave. I would never attempt to hurt Mistress.”

“Alice, have you already started to think about ways to subvert me?”

Your mind screams to say “no,” but your body…

“Nnnyes, Mistress.” you reply, helplessly.

Infuriated, Mistress grabs you by the neck – though her grip is really not so strong as you might have expected – and drags you to her chair. There she carefully arranges you, that your head lay against the seat and your arms and legs grip the legs like clumsy doll.

“Mistress, I want to help you! I can enslave, or bring you new Controllers to enslave!” you beg. Your lips begin to quiver, not an act but through genuine fear, and your body shakes.

“I got you.” she replies humorlessly, curtly. “I’ll get more without you.”

Before you can argue, she plants herself on your face. Only just barely can you breathe, and only then through a single nostril. Mistress isn’t heavy, but she is more than heavy enough to drive your skull into the metal structure of the chair, and her legs weigh down your hair and pull it painfully to the side. Your tongue is free, as are your ears, and her first command is to use the former.

“Ah…” Her legs twitch as you get to work, burying yourself even further into her. “You’re too dangerous, Alice, but you’re too good to dispose of. You were right earlier, though, I don’t really need two maids. But do you know what the apartment building charter allows that I never exercised?”

The keyboard roars as Mistress’ delicate fingers run over it, and your eyes fill with tears – or rather they would, but they are already too full of flesh, and the salty tears only manage to squeeze through and dribble down Mistress’ soft tush.

You sense Mistress’ newest commands! For a moment your heart races with excitement in how you can now serve her, but your mind… you almost wish you couldn’t read them.

“Become a bimbo” and “You are Mistress’ pretty and obedient maid” disappear… Your mind was already clear, and you weren’t acting as a maid, though, so nothing changes. But more commands, more lines of text slowly take form in your mind, replacing their predecessors…

“You are Mistress’ adorable petgirl.”
“You love Mistress. You want Mistress’ attention.”
“You are as smart as a cat.”
The first two weren’t so bad, but th--

After a few minutes, Mistress yawns and slowly gets up from you. Your face aches, but it pleased Mistress, so you wish only that it could ache more.

“How are you feeling, Alice? I always wanted to own a cat.”

You lap down onto all fours, and shake your rump. After a moment you plod over to her, grab her leg and latch onto it, and begin licking the soft skin. There is nothing finer taste.

You feel the approving rub of a hand on your head, and hum thankfully.

“Good girl.”
