The machine finishes him off

Josh does as he is told, and unsticks the dildo from his chair before sitting down and laying back, wondering what she was going to show him this time.

One minute passed, then two, and he could feel that he was starting to lose his erection, maintained before by the stimulation of the machine. Now that he was no longer using the machine to blow himself, the nature of the environs not being particularly erotic.

But suddenly the machine kicks into action, turning on the suction and starting to stimulate his cockhead. The machine starts intensely with the tip, then works down his shaft, holds there for a minute, then rises up again to the tip where the stimulation becomes more intense again. The machine tightens again, sliding down, then up, down, up, down, up. The sensation is amazing, as good as when he was blowing himself, but without needing to suck a plastic cock.

He lays back, closes his eyes, and imagines a beautiful girl sliding up and down his cock.

"Enjoy the sensation," says the voice, "imagine her lips around your shaft, her tongue running up and down over your head. Feel the suction, squeezing her tongue and cheeks against your cock."

For once, Josh is happy to obey. The feeling on his cock is amazing and, unlike before, the machine is clearly going to milk him to orgasm. He has no idea how much time is passing, and doesn't care. He almost wonders why he had bothered searching for the real thing when he could just put one of these things on his cock and get off whenever he wanted.

After a few minutes of this, the voice returns, and Josh is not at all surprised to find she isn't going to just let him enjoy himself.

"It's great to see you having so much fun," she comments, "now why don't you imagine that she has a cock? A nice big thick one that's still wet and shiny from the blowjob you just gave her."

Josh resists this, trying not to let the words subconsciously affect the image that he's imagining. The voice is having none of it.

"Do you want to be here forever?" the voice asks, sarcastically. "The collar lets us see that you're still imagining a woman like you showed us during calibration. If you want your treatment to progress, then the computer needs to tell me that you're imagining a big thick cock hanging between her legs. Imagine how good her blowjobs must be, with all the experience that comes from having a cock herself."

Josh is even more completely broken. Even his imagination isn't his own anymore. He begrudgingly does as he's told, letting his mind give the girl sucking him off a big cock, covered in his spit and flopping back and forward as she slides up and down his own cock. The sensation he's receiving is as amazing as before, so he can still enjoy himself, albeit in a conflicted way. The machine has slowed down a little. Apparently there is more in store for him, and he's not going to be allowed to cum quickly.

Josh was right, as the voice soon returns yet again.

"Good, glad to see you aren't letting a big sexy girlcock get in the way of your pleasure," she continues. "Now I want you to imagine it's your roommate on the end of your cock. Imagine if you and your roommate were blowjob buddies, then you wouldn't need to harass women online. You two could drain each other twice a day, then the only reason you'd need to bother women was because you actually liked them as a person. Not just as a cum dump; you already have one of them on the end of your cock right now. "

He reluctantly complies, disgusted by the thought of penetrating his friend's face over and over in time with the machine. If the machine weren't so amazing, he would have lost his erection; maybe that would have ended this creepy experience. But unmercifuly, the sucking, rubbing, and stroking keeps him hard and **** to cum, despite the uncomfortable thoughts that he is forcing into his mind at his captors' behest. For a few minutes he imagines sitting on the couch being blown by his roommate, pleasure coming from his cock and disgust from his head, until eventually he is given a reprieve.

"OK, you can relax for now. It's not realistic anyway, I know you'd both be imagining a girl while you do it," the voice says. "In the last test you can imagine you're getting sucked through a gloryhole."

Josh does as he's told, relieved to have his mind freed at last.

"Who's on the other side? You don't have any idea," she says mysteriously. "Maybe it's a beautiful woman, like that Connie Perignon or Lily Lou that you got so hard for before. Maybe she's a normal woman, or maybe she has a cock like you imagined. Or maybe it's your roommate, who's too scared to ask to be beejay buds. You don't have any idea, you just have a warm wet hole for your cock, just like you always wanted. "

"But you don't even need to imagine it: you're living it right now," she continues. "Before, you could see the video that the machine was synchronized to, you could see who was sucking your cock. But now it could be anyone. You can't even sneak a peek through the hole. There aren't any lips or fingers to give it away. Just a warm, wet hole that you're gonna load up with cum."

"Are you ready to cum?" she asks. "Tell them how much you're loving it, and maybe they'll make your dream come true."

"It feels so good," Josh says. "I really want to cum."

"You can do better than that," the voice says disapprovingly. "Tell whoever's on the other side of that hole what you really feel, and how much they deserve your cum."

"Your mouth feels so good, I want to fill it with cum," Josh calls out loudly, trying to find the words to appease her. "I don't care who's on the other side of the hole, you're giving an amazing blowjob and I want to blow my load in your soft wet mouth."

"Then do it," the voice orders. "Cum inside them."

Josh focuses on the sensation, and imagines one of the girls from the videos taking cock through the gloryhole, sucking and slurping on his shaft. The image and sensation come together, and after only a few moments he comes closer and closer, reaching the edge just as the machine pulls back to suck on the tip of his cock, overwhelming him with pleasure as the machine ramps up the suction to pull spurt after spurt from his cockhead.

The machine eventually finishes, releasing itself from the unbreakable harness holding it onto Josh's cock, and he slides it off, feeling satisfied, then disgusted, then ashamed as his minds begins to return. He tugs at the collar, but it remains locked in place. As he feared, it seems to be a more permanent accessory.

"So, who was it that you weren't showing me?" he asks the room. "Or was it just an artificial program for the machine?"

"It would hardly be a gloryhole experience if I told you, would it?" the voice responds. "No, you get to fall asleep wondering who was attached to the mouth that just made you cum. Maybe you'll find out one day. Or maybe it will forever be just a hole in the wall."

"Anyway, you've had a big day today. Clean up the machine. You can pull out the sleeve and use the bathroom back there. You've earned some dinner, which will come through the slot soon, but otherwise, you're free to rest and recover. It's been a long day, and you should sleep well before the treatment continues."

For once, Josh is genuinely and uncomplicatedly happy to receive an order. He does what she says, and cleans up his cum, eats his unexpectedly luxurious meal of lasagna, tiramisu, and a half-bottle of red wine, and then collapses back into his chair before immediately falling asleep.
