Fucking machine

Sandra looks at his cock and thinks about how good it would feel in her, but can’t stand the idea of having him inside her. She throbs with need and knows that her vibrator won’t satisfy her and that she isn’t going to let her husband take her tonight. The thought of being relentlessly used by the machine without being able to stop it and being his cum canvas both excites her and makes her feel degraded to barely human. She knows if she goes through with his that he will have a new hold over her and that he will have to think less of her.

Frank starts to stroke his cock, and she is amazed at how quickly he is recovering from his orgasm. She knows it is a bad choice. “Take me back to the guest room.”

He laughs and grabs her by a ring in the collar, making her crawl back to the guest bedroom. He reaches under the bead and pulls out a padded board with several straps on it. “Lay down on your back.” Nervous, Sandra complies. He quickly stretches her hands above her head and straps her wrist to the board, her arms fully extrended. Next a strap goes under her arms and across her chest above her breast. The next strap loosely goes across her waist. He pushes a firm pillow under her ups, raising her hips and then tightens the strap around her waist. Lastly her calves are bound to her thighs, leaving her open and exposed. “You look like a fuck toy right now. Maybe I should take a picture so you can see later exactly what a cock hungry slut you look like. That’s OK. I think one pic today is enough. I’m hoping that this won’t be the last time you visit.” He caresses her cheek. “Now this is the last decision you are going to get to make for a while. Do you want the medium, large or extra-large dildo?”

“Medium?” Sandra can feel how precarious she is and that she can’t resist anything right now.

“You don’t sound sure. Maybe I should lay them on your stomach, so you get an idea of their sizes.” Sandra tries to look, but he blocks her view and she really can’t tell anything by how they touch her, and how quickly he removes them. “Well do you still want the medium?”

“Large.”

Frank grins, “Oh, I hope you are going to enjoy this.” She can hear him moving something between her legs and it getting attached to the board. “Wow, you are really fucking wet. I can see it on your thighs. I’ll still lube this up a bit first.” She hears a spurt from a bottle and he whistles softly.

She gasps as she feels the tip of it touch her pussy. The initial push of the dildo stretches her more than she thought it would and her eyes roll back. Slowly, relentlessly it pushes deeper in to her until it stops and it starts to retreat. When it almost slides out of her it pushes back in. Her eyes start to focus a bit and she can see Frank standing above her, stroking his cock as he watches the machine. She moans and squirms as it reaches its apex and retreats.

“I really wish that was me filling your cunt. Hopefully another time.”

“So thick.”

“Yes, it is a bit thicker than me, that’s why I’m starting it out slow and fairly shallow. I wanted you to have some time to get used to it.”

“Slow? Shallow?” Sandra couldn’t imagine it going deeper but she suspected that it could go much faster.

“Yes. I have this controller here that allows me to adjust the stroke length and speed.” He kneels down beside her and continues to stroke and she feels the dildo push a bit deeper in to her. She whimpers and pushes in to the invading dildo. “I think you like this one. It really isn’t a starter one, but I figured a slut like you could handle it.” The dildo starts to move faster.

“Oh. Fuck me.”

Frank chuckles, “Sorry you passed up that option.” He reaches out and pinches a nipple making her moan deeply. “You are so beautiful and sexy and I sure hope we can play again.” He speeds the machine up again, setting it to a medium slow pace.

“Frank?”

“Hmm?”

“Picture. Please.” Sandra is having trouble concentrating on her words as another orgasm I building.

“Really, but I don’t have access to your phone and your hands are tied.” He snickers at his joke.

“1. 7. 7. 6.” Sandra is trying to hold back the orgasm, but the dildo is giving her no rest at all. She hears the sound of a picture being taken and she can see her boss with her phone taking multiple pictures of her tied up and getting fucked.

“Hmm. Maybe I should do a video too.” He taps the controller with his foot and she can feel it go deeper in to her. “No. I’ll wait until you are really cuming hard from this before I do that.”

“Fuck. Fuuuck. FUUUUUUUCCCCCKkkk.” The orgasm rips through her body and the dildo goes deeper and faster.

She can hear him right next to her ear, but can’t focus on anything. “I’m going to have it fuck you until your mind is blank and then I’m going to carry out naked and put you in your car with your clothes and leave you there until you come down enough to drive yourself home.” Sandra tries to protest, but the dildo goes deeper and faster and she can only moan.

As she moans and writhes in pleasure Frank kneels beside her and masturbates while groping her breasts. He shoots one load on to her stomach and then a next one on to her breasts. He often checks to ensure that the thrusting dildo is well lubricated. After an hour and a half, he turns off the machine, unties her and wipes her clean. He moves her to the bed and covers her with a blanket and puts a bottle of water next to the bed.

Sore and exhausted Sandra sleeps until her bladder tells her that she has to get up. She is initially unsure where she is, but it slowly comes back to her and she is relieved that she isn’t naked in her car. She drains the bottle of water, removes her heels, gets dressed and finds the bathroom. It is nearly 5 in the morning when she finally gets home{if inChastity=true}, places the key to his cage onto his nightstand {endif} and crawls in to bed.
