A fucking machine

"I have a new toy to test on you whore." You say, removing her chastity belt and preparing the toy.

"Sounds enticing." She says with a seductive tone.

Her pussy is dripping wet as you release it from the chastity belt and the intoxicating scent of sex fills the room the moment you remove the metal device.

The new toy you speak of is a fucking machine, a device with a hydraulic piston and a dildo attached to it, designed to rapidly fuck a hole with the dildo. This would most certainly be capable of helping Mia finally achieve the sweet release of orgasm that she had been craving for so long now.

You shift the device into position so that the tip of the dildo is just barely penetrating her pussy. The dildo you opted for is a foot long and has the thickness to match, comparable to your own member and the many cocks Mia was used to taking in her hungry holes.

With everything in position, you switch the device on and it slowly starts pistoning in and out of her pussy. The device is initially on the lowest setting and so it is slowly shifting in and out of her pussy.

"Ohhhh fuckkkk. Finallyyyyy." She moans out.

With a complete whore like Mia however, she would quickly need the highest setting and you're most happy to oblige. You quickly ramp up the settings, placing them half way to the max. The device works its way up to quickly pistoning in and out of Mia. Even at it's highest setting, the device was fucknig Mia at pretty much the maximum rate any human could manage.

"Fuuuu-uuuu-uuuck!" She squeals out as her pussy starts leaking like a faucet.

You can even see a slight bulge in her slim belly each time the dildo punches her cervix.
