There's a list

"So I was thinking, now that we've crossed the threshold of you fucking another man, other men in fact, we should start opening up the possibilities for who you can fuck. In fact, I think from here on out you should be offering up your holes to any man who asks to use them. We can make a dating profile for you on some apps too and set the radius nice and low. You'll be known as the neighbourhood whore in no time at all. And of course, now that you're acting like a whore, it's time you started dressing like one at all times too. This afternoon I'd like you to go through your wardrobe and throw out anything that covers too much of your whore body and then during the week you can go buy some new clothes that really show off what's on offer to every guy who lays eyes on you. Next weekend I think we'll hit up some bars and offer you to whomever takes a liking to you."

Tracy was moaning like a whore at the thought of all these demeaning acts that you had planned for her. She started bouncing up and down on your cock with enthusiasm whilst using one hand to play with her clit.

"Oh fuck I'm gonna cum." She squeals.

You slap her hand away from her clit and she looks down at you in surprise. Before she can say anything you throw her off your cock and onto the bed where she is now lying on her back. Climbing up on top of her, you grab her by the throat and gently squeeze whilst fucking her in a missionary position.

"That's another thing slut, I haven't forgotten what you did in the sex shop earlier, cumming all over that nice man's floors. I think from now on we start seeing your orgasms as a reward rather than an entitlement. From here on out, you're only allowed to cum when I, and I alone, tell you you can cum. Rather than telling me you're going to orgasm, you should start begging for permission, and when I do finally allow you to do so I want you to repeat 'I live to serve' for the duration of your climax. That way you'll be reminded of your proper position in society. Do you understand?"

Unable to speak with your tight grip on her throat, Tracy nods in approval. You decide to test whether she's gotten the point and remove your cock from her pussy and your hand from her neck, inserting two fingers into her pussy and roughly fingering her G-spot whilst rubbing her clit with your thumb. You had discovered early on in your relationship that this was a sure-fire way to get Tracy to cum. This technique was actually what you had used the first time you made her cum, which was also the first time she had squirted, you being the only man capable of making her cum that hard. Tracy reaches a roaring climax after being held on edge the entire time you were talking and releases an arc of squirt juice from her pussy which comes splashing back down onto your bed sheets, she'll be changing those later.

From the moment she starts to cum she starts squealing out "I live to serve! I live to serve! I LIVE TO SERVE! FUUUUUCK!" This is potentially the hardest you had ever seen the slut climax, either due to the minute or so of holding herself on the brink of orgasm or thanks to her new degrading catch phrase. Tracy is now panting in post climax bliss.

She eventually snaps out of her post-orgasm high and turns to you saying, "Hey so, with what you were saying, I'm not sure I can control when I cum as well as you think I can. When I reach that point, sometimes there's no turning back. My mind just clears and my pussy takes over, doing whatever it takes to cum."

"I thought you might say something along those lines, which is why we'll be training you to better control that wild pussy of yours."

"How do you propose we do that?"

"With a vibrator of course. Every day, for as long as it takes, I'm going to send you off to work with a remote control vibrator in your pussy and it'll be up to you to control yourself and hold off your orgasm for as long as required. I'd recommend wearing some black yoga pants to make your pussy drool less visible to all your customers and maybe even lower the lighting in your studio to prevent your class from seeing the wet patch that will inevitably grow around your crotch."

Tracy bites her lip in anticipation, thinking of the prospect of how dirty it would be to have a vibrator in whilst she's giving her classes, with you in full control of her pleasure.

"Yes sir, I look forward to you training this worthless whore to be a better cock sleeve."
