Isobel helps me put her gear on. First, the harness that runs around her ribs - straps over and under her tits, connected at the back and sides. The harness connects, by straps like a long garter belt, to her thigh cuffs, which I make sure are tightly in place, the D-rings on her outer thighs. Ankle cuffs are next. She holds out her hands obediently for the black leather that goes around her wrists. When we're done with all that, she kneels to wait for her collar.
I can see that the straps have put her in subspace. At an ordinary moment, my Isobel would be looking intelligently around. Assessing. Guessing. Thinking. It's taken months of work to break her of those habits, but now she's as sweet and easy as penny candy. On her knees, she looks at me with wide, trusting eyes. Her body quivers with lust and eagerness. She's becoming so beautiful.
Doesn't mean I'm not going to make her work for it.
I reach down and pet her jaw, stroking it from ear to chin. Then I cup her chin in my hand. "What are you today, sweetheart?"
Her voice is fervent and adoring. "Yours."
I tighten my grip. "My what?"
"Your slut."
"And how do you say that politely?"
Isobel whimpers a little. "Your cockslut, sir."
Oh, I have her. "My cockslut?"
She wriggles closer on her knees. "Yes, sir."
I slap her across the face without letting go of her chin. Not hard. We've just started. "We've talked about this." I remind her. "If you can use words, you can answer in full sentences."
Her eyes go wider. Her cheek is a pretty pink where I slapped it. Her chest heaves with the breath she uses to collect herself.
"This girl is your cockslut, sir," she tells me. "This girl used to just be your slut, but that doesn't feel deep enough anymore, sir." She bends her head, tries to rub her cheek against my hand. I don't let her. "This girl wants to be more degraded for you, sir."
"Do you, now." I pet her hair. "That's just right for today, cockslut. Can you tell me again what we're going to do?"
My cockslut nods, and I can see her letting her day-to-day self drop out of control. "Yes, cockslut can tell you, sir. You are going to give cockslut a drink that makes her..." she blushes, fumbling for how to say it. Isobel would say 'stimulated,' but my slut, and apparently even more my cockslut, doesn't use big words. "...Horny, sir. And then some people are going to use your cockslut for you, sir."
"That's right," I praise. "Full, polite sentences, and you called yourself the right thing. What a good piece of shit you are. That is what's going to happen. Crawl over there and get up on the bed for me."
She puts her hands on the floor and scrambles where I've told her to go. The black leather straps framing her back and her ass are such a turn on, dark against her pale skin. I'm almost reluctant to have her turn around, but it is part of the next step.
"Sit up for me."
She sits, and frowns. "Sir, your cockslut is wearing a lot of straps today."
I pick up the prepared cup and sit by her side. We obviously can't do this a moment too soon. "That's so people can do whatever they like to you. You're such a good filthy whore, I know you'll like it too."
"Thank you, sir." She lays her head sideways on my shoulder. "You always take such good care of your cockslut, sir."
I hold the cup for her to drink from. Her face twists up at the first sip. "It tastes terrible, sir."
I tug at her hair with my free hand. "That doesn't matter. I want cockslut to drink it, so you'll drink it all." I tilt the cup ruthlessly over her lip.
She can never control her face while she's under, and the look she's wearing now is completely pathetic. She's disgusted, but I've been conditioning her for months: between the straps, the slap, the speech rules and the petting, she can't refuse. The most resistance she can muster is a brief whimper, and even that comes after she swallows.
