First fuck experimentation

With you sitting on the bed unable to use your hands, you have **** but to watch as Jane picks up the two black dildos and places them next to you. She then attaches the 7 inch one that comes with it, that is the same size as you, onto the machine. Plugging in her phone to a charger, she opens the app and gets it paired. You see her set the depth to it's shallowest thrust, and the speed to slowest. Angling the machine so that it'll fuck her while she's on all fours in front of it. She backs up until the tip of the dildo is pressed against her pussy.

"Okay, time to test this out. Best to start with the minimal settings and then ramp up. After all, if I break it in for us, then we can make sure it gives us both a proper fuck. An with your useless clitty trapped in its prison Mary. It's the only way I'm going to get a proper fuck tonight at least."

You hear the machine click to life, and slowly thrust forward. Slowly spreading your wifes pussy lips, it goes in smoothly about 5 inches before backing up. Jane stops it when it's full extended again, and backs up to fully insert the dildo. You notice that now she's backed up, she's aligned with the ankle cuffs attached to the machine. Though you do remember they can be moved further away from it. Starting the thrusting back up, it's going just a bit fast than before. It's at this point you feel that panty vibe come to life against your clit. The vibrations are enough to give you some pleasure from it, and your clitty is trying to get hard. However, with it trapped, it's fighting a losing battle.

"Mmmm, this certainly has some **** to it. Even with these slow thrusts the **** is very nice. Though before I jump to one of the big black cocks next to you. I think I'll speed it up and maybe have it thrust a little deeper."

The machine picks up speed. No longer is it a casual gentle fuck, it's now at a decent hard fuck pace. You also can see that the 7 inch dildo is going fully inside wifes pussy, before it gets pulled out until the head is just barely inside her. This goes on for about 20 minutes, as she increases the speed to where it's certainly faster than your hips can thrust. After at least 2 orgasms and another 20 minutes of the machine fucking your wife hard, she stops it. During all of this she found a pattern for the panty vibe that was edging you like crazy. Even when the vibrator kicked up to full for several minutes. You couldn't get off, even with you attempting to rock back and forth on the plug for some anal stimulation, it just wasn't enough. You've certainly made your panties wet though. As the panties are drenched in precum from watching her get fucked.

"Oh god, this thing is definitely worth the price we paid. I'm going to need a short break before I try one of the big black cocks. I even found a profile from another user, that promises to give the experience of being fucked by a real life BBC with instructions about how to setup the machine. They recommend that the user straps there ankles in, and sets the ankle bar to one notch away from minimum distance. Which is easy to do, as I can set that now. It also says to make sure the dildo is no shorter than 8 inches, and no thinner than 3 inches in girth. Well that rules out the first BBC we got, as that is only 2 and a half in girth. Well, it looks like I'm going to get fucked by our biggest BBC for you Mary."

During all of this, she hasn't stopped the panty vibe, as it's still going full tilt causing you to moan out in frustation. She's looking at you the entire time, aside from when she makes the quick adjustment to the ankle cuffs positioning. You even see her smile at your moaning, like you're moaning in agreement with what she's saying.

"Aww, does my little sissy want to see her wife get fucked by a BBC? Does she want to also get fucked by the same BBC after? What if I get so turned on being fucked by it, that I lose control of my phone? The description on the profile says it lasts a minimum of an hour. It also says when you use profiles that the user can only stop the profile once started. They can't change any settings such as depth or speed, and if they are strapped in that it reads this as consent to use full thrust and depth of the program without warning. Your moaning is telling me that this excites you, that you want this. I guess that answers my questions."

While she says this, there is a twinkle in her eye. She knows that the moaning is from the panty vibe, and the edging it's giving you and not you moaning in agreement with her . She finally stops the vibe and removes it from your panties. She plugs it in to charge and then starts swapping the attachments on the machine. Taking off the included dildo, she then takes it into the bathroom to be cleaned later. Returning, she then fits the dildo clamp attachment onto larger of the black dildos.

The attachment is designed to hold suction cup dildos much like her strap on does. Feeding the dildo through the appropriate sized o-ring and then fixing the straps onto it, she sticks the suction cup to the attachment and then fixes the straps to secure it into place. Attaching the entire lot to the machine, she runs the machine slowly to give it some lube, and make sure it's not going to fall off.
