The Precipice

Another boring Monday. Andrew sat scrolling through his phone at his office job hoping to get another five minutes break before being forced back into the monotonous job that paid the bills. Rather than reading the news, checking up on sports, or doing anything that could remotely be construed as productive, he was scrolling through porn.

By no means was Andrew jerking off at work, he was creating a lineup of porn to jerk off to when he got home. While many would consider this to be a deviant or unacceptable practice, to Andrew it was a regular occurrence. The rationality he used to justify this practice was simple, it was part of his training.

For many years, Andrew suffered from premature ejaculations. Every time he’s hookup with a guy, he’d climax in under 60 seconds without fail. To counteract this, he attempted to jerk off every day for longer periods to increase his run time. Thus far, he’d made little progress.

As he was scrolling, Andrew kept seeing the same ad, over and over. The ad was fairly simple showing the product in question with a couple of tag lines. Normally such advertisements wouldn’t faze Andrew in the slightest, as he’d just scroll past them without a second though. The constant repetition somehow got to him, almost as if the ad was speaking to him directly. Outside of his normal behavior, Andrew clicked on the ad and purchased the product.

After entering his shipping information, Andrew promptly forgot he’d made the purchase and returned to his work.


Andrew pulled his car into his complex’s narrow parking spaces and groaned. For a Wednesday, it was killer. The only saving grace was that the week was already half over. Walking up to his door, he spotted a package awaiting him. Forgetting what it could contain, he dragged it inside and opened it.

Inside, Andrew found another box, this once printed with bright colors proudly displaying its contents. He read over the packaging and wondered when he had purchased this machine, but he wasn’t complaining.

At first glance, the item appeared to be your typical fleshlight with some extra plastic. Upon further examination, one would discover it had an internal motor, thus making it an auto-fleshlight. The only other immediately identifiable feature was the base containing several spots for straps to attached.

As Andrew pulled the devise out of its packaging, a card came with it and landed on the table. Picking it up, Andrew immediately understood why he’d purchased it. Across the front read “Experience the new AI masturbatory training! Download the free app to get started today!”

Andrew rolled his eyes upon reading it. Of course it required and app, because everything needed a bloody app these days. Reluctantly, he scanned the QR code and loaded it up.

The first instruction it gave was simple, attach the machine to his dick with some lube. Andrew did as instructed and moved on. Step two was to enter his average masturbation time and desired time. Blushing, he entered 1 minute for the former and 30 minutes for the later. The final instruction was to turn on some porn and relax. He loaded up one of his favorite hentai onto his big screen and sat back on the couch while starting his stopwatch.

Immediately, the machine started stroking his cock. The internal mechanism ran along three quarters of his shaft while another mechanism descended onto his head and began slowly rotating back and forth. Quickly, the stimulation forced his cock to harden, filing Andrew with lust.

30 seconds passed and Andrew already felt he was getting close. His hand tried reaching for his cock but he stopped himself, knowing the machine would take care of that for him. 55 seconds and he was breathing hard as he approached the precipice of orgasm. 59 and he was ready to burst.

Mere moments from crossing that line of no return, the machine automatically backed off. Slowing down just long enough to prevent orgasm, Andrew was frustrated. He wanted to cum but understood this must be part of the training.

Five minutes and Andrew couldn’t take it anymore. He’d never been hard and stimulated this long in his life. Already he’d lost track of the number of times he’d approached the precipice of orgasm just for the machine to back off and deny him. Finally ready to reach his orgasm, he attempted to remove the straps so he could finally cross that sweet line or orgasm.

Fumbling with the straps, they wouldn’t budge. An internal mechanism kept the straps locked and the machine attached to his cock. Once again approaching the threshold, he tried grabbing the machine and using it like a regular fleshlight, forcing the stimulation to increase stimulation just long enough for him to finally fucking cum.

As he stroked, the internal mechanisms slowed down. Andrew tried stroking harder with the half inch of wiggle room the straps gave, only for the machine to go cold and reduce his boner just enough to prevent orgasm. The machine was prepared to counteract any action Andrew made to cum.

10 minutes of trying resulted in nothing, and Andrew finally gave up. Laying back, he let the machine work. Slowly the machine worked his cock. Despite himself, the machine felt good as it stroked his cock and porn played before him. So fucking good as it stroked, clouding his mind with never ending pleasure the exact flavor of nearing orgasm.

His mouth hung open, tongue hanging out, drool dripping down as porn continued to enter his sex hazed mind. Finally, he’d reached the time limit and the machine sped up. Finally, he was allowed to cum.

Andrew’s cock ached as it finally shot his load into the machine, feeling it’s warm gooeyness encompasses his throbbing member. Simultaneously, it was the best and most disappointing orgasm he’d ever experienced. It was the best as no orgasm had ever felt so strong, disappointing because it didn’t feel as good as approaching the precipice again and again.

Andrew removed the machine from his cock and attempted to stand, only to collapse onto the ground exhausted. A notification popped onto his phone and with what little strength he had, he checked it. The app was congratulating him and encouraging him to go longer next time.


Stepping into his apartment after work Thursday, Andrew’s loins were alight with carnal need. The orgasm the day before had been excellent, even if it was exhausting, but as always his lust soon returned.

He was torn at the prospect of using the machine again tonight, unsure if the torture he’d experienced the day prior would truly help him last longer in bed. Remembering what a coach from his high school days had told him many times, he decided to give it a week. If there’s no improvement in his longevity, he’d quit.

Stripping off his clothes, Andrew streamed some porn he’d picked out earlier to the TV and hooked the machine up to his cock. Opening the app, he was greeted with a prompt asking how long he wanted to go. He thought for a moment before entering 10 minutes.

Immediately the machine came to life, the internal mechanisms stroking his cock and rubbing the head.  Bringing him to the edge and keeping him there. The carnal haze began tickling the corners of his mind. Each time he approached the precipice and the machine backed off, the haze crawled slowly forward.

The 10 minutes passed, and the machine granted him an orgasm. Again, the orgasm was nice but felt short, fleeting, a temporary pleasure compared to the slowly building haze of the machine. He unhooked the machine from his cock and left to get cleaned up.


The machine never left Andrews mind that Friday. All though out work, grocery shopping, and the drive home, the rhythmic stroking and pleasure it produced jumped to the forefront of his mind, the constant desire to hook it up again.

Wasting no time at all, he threw his groceries into their proper locations and tore his pants off, accidently busting a seam in the process. Andrew jumped onto the couch and fumbled as he once again attached the machine to his cock. Before even turning on some porn, he opened the app.

When prompted for how long of a training he wished for, Andrew froze for the first time. How long should he go? With no other plans for the rest of the day, he entered 60 minutes.

The app thew an error at this time entry. It wasn’t designed for marathon stroke sessions. More than that, the designers were concerned that it could produce addiction and created multiple hard limits in their work. On the current version, it could go no more than 45 minutes.

Resigned to this limitation, Andrew entered the maximum time and laid back while the machine got to work on his cock.


It had taken several weeks but Andrew had finally done it. Through difficult work he’d taught himself how to code well enough to create a simple app to turn the machine on and off. Skimming a copy of the anti-orgasm AI, a fairly complex set of code that utilized machine learning to accurately identify when a user was about to cum, was truly a challenge.

Utilizing some software, he’d found on a shady website in the less than easily accessible portions of the internet, he’d managed to piece together and incorporate the AI into his rudimentary app. Finally, he was ready to test.

Strapping the machine to his cock, he pressed the on button. The machine came to life as his cock grew hard. Carefully it brought him to the edge, and unlike before, held him there. His work was finally complete. He now possessed a device that would bring him to the precipice of orgasm and hold him there indefinitely. In that moment he considered adding a button to induce orgasm, but that could wait. For now, he could sit back and feel the tingle of carnal haze slowly consume his mind in peace.
