Ask her to give you a tour. With a twist.

You look at Madison as she begs for your permission to cum, but you have other ideas in mind. Besides, she volunteered to be at your service for the next 24 hours, so it's her job to please YOU, not herself.

"NO, you worthless slut, you may NOT cum. But don't you dare stop pleasuring yourself."

Madison let out a throaty moan as your order registers. She looks at you pleadingly as her hand kept working her soaking wet pussy.

"Please master... Please let this **** cum. I'll be good, I promise."

You had walked towards the wardrobe containing your new clothes and toys, and looked over your shoulder at the big-breasted slut.

"Yes, you will. Because I will not be merciful if you don't."

You pick up a pair of professional-looking steel handcuffs, lockable with a fingerprint so only the true owner can unlock it. You turn towards Madison and found that she was still dutifully using her hand to fuck herself. Her eyes were closed in concentration, doing her best to keep herself from climaxing. You could see her body begin to shake as she was getting close to cumming.

"Are you close? Does my filthy whore wants to cum?"

Not bothering to open her eyes, madison began to plead with all her might.

"Yes... Your filthy whore wants to cum so bad. Please allow me. I'll do whatever you want. You can do whatever you want. But please let this worthless slut have her orgasm."

Wow, she was really getting into it now. For a moment you are tempted to give in, but then you remember something she said, and you smile evilly.

"Okay, if you are so pathetic that you can't control yourself, I guess there is no helping it then. I want you to get yourself as close to cumming as you can get. You can cum when I tell you to."

Madison's hand increased in speed, and her frantic thank yous mixed with the sopping sound of her hand slapping against her dripping cunt. Soon her entire body went rigid as she was just barely able to hold her orgasm away. You silently walked behind her and knelt down, prepared to strike the moment her resolve failed. And failed it would, a slut such as Madison was not used to be denied her pleasure or orgasms, well she would learn tonight.

"I'm sorry master," She screamed. "I can't hold back anymore, please forgive this worthless **** for failing your orders."

The moment she said that you grabbed her wrists, and using every ounce of your superior strength, pulled her arms behind her. With a metallic 'click' the handcuffs closed around her wrists, and you pressed your thumb against the fingerpad to lock you in as her master.

Madison as slumped forward, still on her knees, with her legs spread in a wanton display of sexuality. her breath was fast and heavy. You walk back towards the wardrobe and pick up the next toy that caught your interest. A large dildo, complete with a clit stimulator, fitted onto a pair of durable tight-fitting pants. You return to Madison and roughly push her onto her back, the little whore moaned sensually at the rough treatment. you slide the pants over her long, toned legs, and she sighed contently as the large toy penetrated her wet cunt. The clit stimulator fell neatly over her exposed nub, and you found out the tight pants were made to fit perfectly around Madison's plump ass.

You grabbed her by the shoulders and helped the panting woman to her feet.

"Come, your master desires a tour of the facility, and you are going to provide it."

Madison struggled feebly against the steel cuffs but found them unbreakable. She lowered her head and mumbled a quiet response.

"Yes, master. Your slut is eager to show around."

You open the door and lead her out. As you close the door behind you, you take out the tablet device they had given to you and opened the controls for the dildo and stimulator between her legs. You pressed the low button, and watched with sadistic glee, as Madison's steps faltered for a bit.
