Overcoming her gag reflex

Entering your bedroom Jane tells you to sit on her vanity stool facing the end of the bed and not move. She then walks into the wardrobe and wheels out the fuck machine and sets it up at the end of the bed. She then goes back into the wardrobe and comes back with the two big black dildos, and holding a some straps. She places the two dildos onto the end of the machine along with some of the straps, and then walks over to you with a single strap. She walks behind you and tells you to keep looking forward, as you feel her wrapping something around your waist. Then after she's finished with your waist, she takes one of your wrists and wraps a strap around it, before quickly repeating that with the other wrist. You are now sitting on the vanity stool, with your arms strapped to your waist. You can't remove them or reach enough to undo the waist strap.

"There we go, nice and secure so you can't interfere with what I'm going to do. I know when we started dating you were a little upset that I never seemed eager to give you a blowjob. An that I only really give them to you on special occasions. I also know you wish I would learn how to deep throat you, when I do, as I only ever get the first few inches in before I gag. Well tonight I'm going to change that, but obviously not with your clitty. Tonight I'm going to practice giving one of our big black cocks a proper blowjob, while the other fucks me hard."

While she's saying all of this, she has come out from behind you and stands in front of you for a few minutes bending over to look you in the eyes. She's doing this and running a finger along the camel toe of your panties, a long the outside of your locked clitty.

"I've found a profile for the machine on the app, that says it's designed to teach the user how to fuck and suck at the same time. It also says that if your not experienced at deep throating that by the end of it you will be. From reading some of the comments, it sounds effective. They say the way it **** them to either learn how to get past the gag reflex, or be **** to deal with gagging on a cock. We both know the reason I dislike blowjobs is that I struggle with my gag reflex, but even though I've been practicing recently. This should be just what I need to break past it."

She walks over to the machine, and proceed to set it up for her use. Taking one of the dildos she gets it set up on the machine, and the other she sticks to the end of the bed with its suction cup. She then kneels down in a doggy style position and quickly tests the positions of the dildos to make sure they are good for her, quickly adjusting the one she intends to give a blowjob to a better height. Then standing up again she takes the straps off the machine and you see her attach them to the machine, and then loop them around the bed legs before securing the loop to the strap.

Realising that the way this profile works was by forcing the machine to be a set distance away from a dildo, you quickly figure out that she's setting the machine up as per instructions from the profile. She then gets into position between the dildos, and takes the blowjob ones head into her mouth. Then picking up her phone she has the machine extend out until just the head of the dildo is in her pussy, she then releases the dildo from her mouth and you see her enter a few things into her phone.

Next she takes the dildo back into her mouth until she gags on it, and very quickly extends the machine out until the other dildo is completely filling her pussy. The very nature of her getting filled causes her to moan around the dildo in her mouth and she slips forward a tiny amount, as the machine pushes into her still. She then presses on her screen and the machine starts to pull the dildo out of her, where she pulls back off the dildo in her mouth. She then stands up and wipes away the drool from her mouth, and picks up the emergency stop remote from the side of the machine. She then walks over to you and places it into your hand.

"I'm giving you this, as I need you to make sure that the machine stops if I look to be passing out, or in trouble. I know you'll know when that will be, and I expect you to not press it before then. You're going to sit there otherwise, and watch as I learn to deep through a big black cock. You get to know that I'm going to potentially have another cock other than yours in my throat for the first time tonight. Enjoy the show Mary."

Getting on her hands and knees between the two dildos, and gets herself in the right position. Taking the head of the dildo into her mouth she taps her phone and the machine starts slowly thrusts forward, while she reaches back and positions the head of the dildo at the entrance to her pussy as it pushes into her until it's half way in. You then hear a tone from her phone as the machine then thrusts the dildo into her forcing her to take the dildo in her mouth deeper, but not quite forcing her to gag. Then slowly it retracts for a few seconds, before it stabs forward again. This time it forces your wife forward enough to gag, and it holds her there for several minutes.

Retracting again and letting her let go of the dildo in her mouth, she recovers her breath for a minute. Then it slowly pushes forward making her quickly reach up and take the dildo back into her mouth, before it stabs forward again even harder than before. Causing a greater gag reflex from your wife, it holds her there for at least 4 minutes, where she does seem to start struggling. You feel like pressing the button but it finally restracts for a few minutes letting her breath heavily through her nose. Thrusting forward again you see her getting slightly deeper on the dildo, and her throat slightly expanding. She's still partially gagging, while she tries to breath through her nose, as she tries to avoid gagging. The dildo pushes forward again, forcing more of the big black dildo in her throat and forcing her to take more and more of it. Eventually it retracts fully, allowing her to quickly pull back and start breathing heavily.

"That... Was... Intense..."

With less time to recover the machine pushes forward and she again has to quickly take the dildo back into her mouth. It stops half way in, allowing her to fuck herself between the big black dildo in her mouth, and the one in her pussy. As she's thrusting forward and tries to self gag the dildo, the machine does a hard thrust forward. Forcing her to take nearly three quarters of the dildo in her mouth and causing to gag once again, though slightly less so this time. She's breathing comfortably through her nose, even with the slight amount of gagging she's having to deal with.

The machine then thrusts forward even more, forcing her to try and take more, but she's stuck at three quarters of the dildo in her mouth. Finally though, as if some barrier has been breached, she stops gagging completely. Then, as she stops gagging, she slides the dildo the rest of the way down her throat. Hearing her make a small happy noise at fully deep throating the dildo in her mouth, she has to wait there for a few minutes before the machine retracts again. As it pulls back she goes back with it, then it starts to thrust again before she's even half way off the dildo.

Suddenly the machine starts to fuck her hard, and with a purpose. The past 15 minutes of the profile being to **** her to overcome her gag reflex before pounding it home that she's now a deep throating cocksucker. You sit there for another 15 minutes as the machine continually pounds her, and forces her to take every inch of what is essentually two big black cocks from head to fake balls. Multiple orgasms later, your very worn out and tired wife falls limp as the machine stops the profile she used.

"Mary, that was intense and amazing. I'm now capable of deep throating a big black cock, and your locked for the next week. Meaning you can't experience it for yourself at all, until unlocked. Now, I think it's time I unstrapped you, and we get into bed. First though, I'm going to get my strap on, as I wanna fuck you to an orgasm while we watch some porn."
