A surprise visit

You lean against the wall, admiring the view. Zatanna is cooking dinner, wearing an apron and nothing else. It's been almost two weeks since you enslaved her, and you still haven't gotten tired of this sight.

"I love watching you **** away like that," you say. "You know why?"

"No, Master," she murmurs. You're not sure whether she actually doesn't know or if she's just giving you the answer she knows you want. This is the one flaw in your otherwise total control over her, and it sometimes bothers you -- while normally you can discipline her if she doesn't follow your orders, you can't really enforce an order to tell the truth because you have no way of knowing if she's broken it or not (unless it's such an absurd lie that it's obvious, like when she tried to claim that Superman spends his days disguised as a reporter).

You saunter up behind her and slip your hands beneath her apron to squeeze her tits. "It really drives home how completely unfair our relationship is," you whisper in her ear. "You've doing all this work to make sure I have a nice dinner, and you're not going to get to eat any of it. You're having the same cheap TV dinner you have every night." You spend a few moments mauling her breasts while she does her best not to let this interfere with her cooking, knowing the punishment that awaits her if she makes a mistake.

Somewhat to your disappointment, she doesn't respond. Nettled, you decide to go further in your effort to grind her into the dirt. You remove your hands from her chest and say, mock-thoughtfully "In fact, you know what I've just decided? You don't get dinner tonight at all." You pat her ass. "You could stand to lose a few pounds anyway," you lie.

"...As you wish, Master," says Zatanna, with only the faintest unevenness in her voice. Her fingers are white-knuckled around the spatula. This sort of thing has been happening more often lately; when you first acquired her she tried to be careful never to show any dissatisfaction with your rule, but that control has been slipping the last couple of days.

BZZZZT goes the door buzzer. You walk over to it and press the button "Who is it?"

"Wonder Woman" comes the electronically-distorted voice. You and Zatanna exchange confused glances. "...All right, come on up," you say, and push the button to buzz her in.

"Probably here to talk about superhero stuff with you," you say to Zatanna.

"No," she says, sounding disgruntled. She is turning down the heat on all three burners she's using. "We have a communication setup for that." She stabs the meat with a carving fork, too hard. "She wants to talk to you."

You blink, a bit taken aback by her anger, but before you can respond there is a knock on your apartment door.

You go over to the door and open "So, Wonder Woman," you say. "What brings you here?"

"Yes," says Zatanna, coming up behind you. "Why have you come to speak to my owner?" There is a definite edge to her voice.

Wonder Woman licks her lips nervously. "I wanted to give you a gift, John. An invitation to a... special event."

You eye her suspiciously. Is this a trap of some sort? Has she figured out that you were mind-controlling them? "What sort of event?"

"It's a surprise," she says evasively. "But it's a special present, one that only I can give."

This does nothing to allay your fears of a trap. But no, that can't be it. Wonder Woman wouldn't need to resort to trickery to take you in, even with Zatanna there to protect you.

"I think Master's probably too busy enjoying his favorite to waste time with you," says Zatanna snidely. She wraps an arm around you and snuggles up close. "He's only cum in or on me eight times today, so we've got some catching up to do." (In fact, it's only been three times today, which if anything is slightly more than average.)

"Zatanna," you say sternly, "that's not your call to make." You rub your chin thoughtfully. "When is this, and how long will it take?"

"Six in the afternoon tomorrow," Wonder Woman says promptly. "And as for how long... well, that'll depend on your stamina." She gives you a wink that does not fully conceal the desperation in her eyes. Whatever present this is, it's her Hail Mary pass, her last-ditch attempt to win you -- if you say no, you're certain, she will never go after you again.

"All right," you say.

Wonder Woman gives you a huge smile. "You won't regret it," she promises. "I'm pulling out all the stops on this one." You take a moment to enjoy the sight of her retreating ass before you close the door.

You take another bite of the steak, then glance at Zatanna. She has been kneeling beside your chair for the last fifteen minutes, in the pose you have told her to adopt when she has something to say to you. You let her wait a bit more, just to make sure she remembers her place, then say "All right, slut, what is it?"

"Master," she begins, "Are you really going to accept Wonder Woman's 'gift'?"

You shrug "Sure. Why not?"

"Well," says Zatanna, "I think that when two people have an... arrangement like ours, they're sort of implicitly agreeing to monogamy."

You pat her on the head condescendingly. "Yeah," you say, "but the nice thing about our relationship is that it doesn't really matter what you think."

"Master," says Zatanna desperately, "Please, don't go. I'll do anything you want if you just tell her no."

You give her a blank look. "You'll do anything I want anyway," you point out.

"Yes, but--"

"Zatanna," you say sternly. "Hairbrush."

She quickly scampers off to retrieve the item in question, having learned what happens if she keeps you waiting.

Once she returns, you take the hairbrush from her hand and give her an expectant look. She obediently lies across her lap, lovely buttocks turned upward.

"I think forty strokes this time," you announce. "And say your mantra after each one. One!" and with that you bring the hairbrush down hard against her ass.

"Ah!" she exclaims "Um, Master is better and smarter than me in every way."

"Two!" SMACK

"Master is better and smarter than me in every way!"

"Three!" SMACK

"Master is better and smarter..."

...

..."Forty!"

"Master is better and smarter than me in every way," gasps Zatanna.

You wait a moment for her to unclench her buttocks, then deliver one final blow to her unsuspecting bottom, which has turned a lovely shade of red.

"Gah! M-Master is better and smarter than me in every way!"

You let her slide to the floor. "And what do you say now?" you prompt.

As you have trained her to do, she prostrates herself. Forehead pressed to the floor, she says "Thank you, Master, for helping me become a better **** for you. It is more than I deserve."

"That's right, it is," you say. "But maybe I'll have some mercy and let you eat something after all." You spear a piece of steak on your fork and hold it above her head. "Beg!" you command.

Zatanna obediently adopts the posture of a dog, hands held in front of her and tongue lolling from her mouth as she puts on an idiotic expression with her gaze fixed upon the steak.

You lower it towards her mouth. She opens her mouth wider in anticipation. At the last possible second, you pull the steak away. "Nope!" you say cheerfully. You laugh at her resultant expression before turning back to enjoy the rest of your meal.
