Come back! Love this story...
I’m ashamed to say, I was weak.

Not physically. No, even without the suits assistance, I was a wall of muscle now, and the way I had been throwing weights around lately, I was probably the strongest person in the state. But with the suit engaged, I was positively super-heroic.

Not mentally, as we’ve already more than established — though I certainly had a blind spot or two.

But my willpower was another story.

The routine was now pure habit, and I barely noticed how much I lifted or how many reps I did. The pleasant burn of exercise was familiar, as were the massive doses of whatever I’d mixed it in my sleep, and the immense meals. Even the distressing bathroom visits barely phased me now (and they’d been quite upsetting at first). I was essentially on autopilot. And why?

Because nearly the whole time, I was getting fucked and fucking to the absolute limit by my own suit — a suit I realized was now so throughly part of me it was unlikely to ever be removed.

Well, I say I realized, but it wasn’t like I suddenly had that thought. No, it just gradually dawned on me, as a series of slow revelations. At some point I noticed that the glossy shine had utterly vanished and even knowing it was there, I couldn’t tell. Not even with my enhanced eyesight, which thanks to the suit was capable of seeing in some pretty astounding detail, nor with my sense of touch, which was also unbelievably sensitive. My whole body was an invisible erogenous zone, hardwired to my arousal.

I’ve mentioned before how thoroughly satisfying the suit had made my masturbation — though that’s hardly the right word for being sexually stimulated in an undulating series of teasing but firm strokes and probes. Thanks to all the sensors sewn into my entire dermal layer, the acres of porn and data it had collected, and goodness knew what else, the AI was capable of being the most thorough and generous sexual partner ever, physically. It even capitalized on kinks I wasn’t fully aware of having.

Knowing that it intended to repeatedly bring me to the edge in order to grow my cock and balls to an implausibly record breaking size? And that there was almost nothing I could do about it if I chose to rebel?

Fuck. Apparently that was even hotter than being fed your own two liter bottle of cum.

I was so lost in sensational pleasure that I didn’t even really pay attention the delivery, and I might as well have slept through whatever I did after signing for it.

But that night, I had a bit of a moment. I lay in bed ready to pass out, thoroughly exhausted and drained for what was likely the tenth time, when I realized that, laying on my back, the tip of my dick was resting in the crevasse between my pecs. The spurt of cum was routed almost instantly to my mouth and I swallowed the load greedily. Idly I wondered how big I was...

We are ahead of projections. Which measurement would you prefer?

Dick.

You are now 37.2 centimeters long.

A bit over 14.5 inches.

Correct. Overall, your growth has not tapered out as expected, though we are still within projected range for this phase. I see no cause for alarm.

Wonder why? Maybe because I’m drinking so much of my own fluids.

That is a reasonable hypothesis. The effective dosage did not account for that possibility. It is likely that your kidneys are not able to fully process the supplements encouraging your rapid growth.

Hmm. I will want to run those numbers tomorrow. I need to understand more of this, now that the phase is winding down.

Noted. For now, rest is required.


And as I drifted off, lulled by the gentle ministrations of a full body massage and utterly relaxed, I didn’t even register that my night was only beginning, and that I had never instructed the AI not to keep working my body while I slept.
 
I woke up feeling overstimulated — at once tired and energized, and more than a little horny.

Good morning, Mark. Here are some reminders you asked for.

This is your last day on this phase. Tomorrow, Devon returns.

Devon....mmm, the memory of his scent made me spring wood...

*thwack*

Wow....a lot of wood, apparently. I peered over my enormous chest to find my own monstrous dong staring me in the eye.

Jesus. How...

You are nearing the end of this phase. Are you pleased with your progress? It has exceeded projections for efficiency and efficacy.

I gently cradled the head of my enhanced dick, only to have it react by surging a little larger. It wept precum at my touch, and the upper third flushed an angry pink, the head puffy and shiny.

Your genitalia has exceeded parameters, despite the adjustments to yesterday’s dosage and exercise.

“Where are we at now,” I said, in awe.

Your erect penis just reached 42.2 cm. Slightly over 16.6 inches. I predict you will reach maximum for this phase by tomorrow morning.

I couldn’t wrap my brain around it. Hell, I couldn’t wrap my hand around it that easily either.

I leaned forward, too tempted NOT to try. It would be unthinkable. A crime, not to make the effort.

It was barely any effort at all, my powerful torso folding like an accordion. Only the muscle itself proved any impediment, with my oversized pectorals and thick abdominals engorging themselves with the effort. Oh my god it was amazing.

I attacked my own prong with gusto, the suit naturally enhancing my efforts. Before long, nearly half the beast was lodged in my throat, which responded by undulating in pleasurable waves. The suction increased to near painful levels as I tightened my mouth’s strained hold on the intruder. The pleasure ratcheted up exponentially, as various micro adjustments were triggered by the suit’s recent practice — only I remained mostly in control this time, conscious of how the pleasure kept feeding on itself. I was an oroborous of fucking sexual stimulation.

I nearly blacked out when I came, as a cacophony of nerve endings went all fireworks on me.

I woke up to find myself already dressed and eating. A pile of chicken breasts and greens and beans was half demolished in front of me, and a blender full of protein shake and chemicals was sitting half empty next to me. My entire body ached and it seemed almost like the table was farther away.

Mark, I need to adjust the feedback you are getting from self stimulation. It was not a factor I had anticipated. I am concerned about your blackout. However, we have a schedule to keep if you are to achieve your goals.

I looked out the window and saw it was nearly dusk.

Correct. You have been unconscious most of the day. However, that has not proved an impediment to your progress. In particular, the skeletal growth has completed, and your muscles and connective tissue are nearly fully integrated. We will focus today on flexibility and coordination rather than muscle mass increase.

You had me work all day without me knowing?

Yes. As noted, this phase was meticulously planned out to maximize your potential. The results exceeded projections. I anticipated you would be pleased with the results, and there was minimal danger to you while the suit put your body through its paces.

I could feel the panic kicking in again — it had basically kept living my life for me while I was blissed out on sex. That could not be a healthy or sustainable state of affairs.

Mark, your anxiety indicators are all rising. Shall I calm you down?

Wait, what?

Allow me to demonstrate.

Instantly, I felt calm and collected, like a switch had been flipped. The sensation was surreal — and that’s saying something, given I had recently passed out from sucking my own oversized cock.

There. The nano probes are releasing endorphins. Similar to what you naturally produce after a good workout.

A chill ran down my spine. If this suit could trigger hormone and other chemical releases within my body....

Was that not clear from prior interaction? For much of the past month, I have been learning your bio systems and assessing reactions. I sense trepidation. I can counter that...

No! Just....let me ride this out. I need to think. Don’t help me right now.

The chill didn’t go away. The more I considered, the more dread I felt.

It had been learning my biology at the ground level, and now it was playing me like a harpsichord. It had become almost a copilot for my body for weeks now, but I was still thinking in terms of the outer suit. But of course, the nano weave had spiraled down into my body some time ago, and apparently it was all over my glands with its tendrils, ready to “help” as it saw fit.

Thank goodness it was trying to help me and anticipate my needs. If it were to be at serious odds with my direct orders....
 
Beautiful description of Mark's penis and orgasm.

With that last line, I can't tell - is Mark just being naïve, considering the suit's already gotten in some small tussles with him about orders? Or has it already messed with his mind to make him think it's doing what he wants?

Still really loving this story. You have a great vocabulary. Oroborous?
If you guessed I was one of those kids who looked up words I didn’t know, you were right — but in that particular case, it’s a word I picked up from Neverending Story.

I woke with perhaps the most epic case of morning wood the human race had ever been subjected to. In fact it was the sensation of that massive organ being stimulated that woke me. As the blood flowed into the beast, the suits feather touch stroking began. It was beyond all reason, but it was also a distraction.

“Stop the stroking. I need to concentrate,” I said.

Outside, however, it was raining like mad.

Good morning, Mark. I detect concern about the weather and Devon’s planned arrival.

Among other things.

His connecting flight was routed to a different airport, and his plane landed prior to the storm. Accounting for traffic and assuming no unexpected delays, he should arrive in three hours.

Ah, but would he come here first? And would he like what he saw, or freak out? I mean....fuck, Aside from the the height and muscle growth, my dick was now the size of two huge guys. It looked like a bad photoshop, and if it weren’t throbbing with my heartbeat, I would think it was fake.

An update would seem in order. As noted, your phase one adjustment has largely followed predictions. Phase one is complete and successful. Your body now requires rest and significant nutrition. Today’s efforts will be on adapting to your new body.

I noticed. In fact, I realized I had been fed intravenously while I slept — something I must have done in my sleep, or rather the AI must have used me to do it.

While you have gained another half inch or more in your primary muscle groups, the most noticeable change is your genitalia. As you have probably noticed, your penis length has reached a new plateau. I do not expect further growth without a second regimen. You have now exceeded your desired penis length and girth, and have reached a size that no human has ever reached while remaining functional.

How big is this thing now?

Your current penis length while erect is 44.8 cm, or 17.5 inches.

Holy fuck. That was inhumanly large.

I wish I wasn’t so turned on by it.

My apologies. You have now reached 45.8 centimeters, or slightly over 18 inches.

It was insane. That was two big dicks worth of meat, three normal ones!

The treatment has exceeded expectations in that regard. However, please remember that your masturbation protocol must be maintained for proper health. Your testes will overproduce otherwise. But I do not suggest continuing to consume your product at this time. I shall harvest as much as possible prior to Devon’s arrival so your need does not interfere.

And with that we were off to the races again— for all my strength, I really did need to come, and I knew that the suit would provide the most efficient, effective stimulation. And it did so, edging me for half an hour and providing enough overstimulation that I nearly blacked out again. That first orgasm produced nearly a cup of jizz, and the next two were equally thorough, the last assisted by a timely rear intrusion. No longer able to sweat conventionally, I found myself panting and dizzy.

And then suddenly very calm and collected.

“Stop doing that,” I complained. “I need to feel properly, and deal with emotions and sensations on my own,” I said.

It is my function to assist you in reaching your physical goals. Emotional highs and lows drive impulsive decisions that may not be compatible with core programming.

I got up, grumpily. Time to see what I’d managed to do to myself.

Standing in my mirror was caricature of my former self, barely recognizable — even my face had thickened up.

  • Final height: 192.2 cm, or 6’3
  • Final upper arms: 49.9 cm (19.6in)
  • Final chest is 140 cm (55.1 in)
  • Final waist: 84 cm (33 in)
  • Final thighs: 76.4 cm (30 in)
  • Final calves: 48.8 cm ( 19.2 in)
  • Final neck: 48.75 cm (19.2in)
  • Final weight: 105.7 kg (233 lbs)
So I had basically landed in he upper range of projections, but with a dick that blew it all out of the water.

Correct. Now that you have reached the end of the stage, you will have minimal directed suit assistance. I believe you also wish privacy of a sort for your visit with Devon. Only basic assistance protocol will be in play for the next 24-48 hours.

Great, that would give me time to—-

*growl*

Right, after I ate and showered and dressed.

And hopefully before Devon arrived—-
 
Among the many exercises I'd been doing were several designed to keep me limber. It had been the one real advantage I'd had as a scrawny teen, and as I'd become more muscle-bound, it had taken real effort to stay flexible. Easily two hours a day had been spent on maintaining as much flexibility as possible; luckily, the idea of becoming completely musclebound was not one I'd found particularly enticing.

Even so, it was a struggle as I raced around the house trying to simultaneously eat and tidy up. There just wasn't space to move and my new bulk was proving an obstacle. All the more frustrating because the AI calmly informed me of the remaining time every so often, and prodded me to eat and whack off on schedule.

Originally, I'd had a basement apartment of sorts in my folks' house. It was accessible from within the house, but it also had an external door that led to a short flight of stairs that emptied between the garage and the house. The little 10-foot patch was fenced from the front, so you couldn't see it from the street -- something that had simplified my efforts, bouncing between the garage and the basement. Inside the apartment, it was a little cramped: the bedroom, with a queen size bed that I now fully needed; a room that I thought of as a den, which had my computers and entertainment system in it; a storage room that I'd co-opted as a lab. And of course, luckily, a full-size bathroom with an oversized shower. There was also a little area with a sink, microwave, and fridge, but my growing nutritional needs had spilled over into the main kitchen upstairs some time ago -- I used the downstairs stuff for samples and snacks. My folks had originally finished off part of the basement for my aunt, who'd stayed with us for about two years, assuming that I'd eventually take it over as my ...ahem... need for privacy increased.

Anyway, it meant that in practice, with them away, I had the run of the place, but my recent purchases had rather taken over. I spent several hours just cleaning the place up. It was like I'd had a party while my folks were away.

Shit, when they returned, I'd have a lot of explaining to do. Hell, when DEVON arrived, I'd have some explaining to do.

Just as I thought that, a text popped up.

Oh yeah, that happened too. My texts just showed up as part of a gaming-style heads-up display, superimposed over the real world. Displayed on the layer of suit that covered my actual eyeballs (transparently).

DEVON: Hey. Just landed. You home?
ME: I'm home
DEVON: Gotta get through customs and stuff, and then my cousins are dropping me off at home. Mind if I swing by after?
ME: Come on over! Just text when you have an idea of your ETA
DEVON: You got it. Should be around 3-330.
ME: Works for me.

That gave me a solid three hours to finish up....and figure out how to explain things.

One side effect of the "defrag" the suit did to carve out space for its processing in my brain -- well, aside from the part where it didn't freak me completely out that it had done so -- was that I seemed better able to multitask. I mean, I could probably have let the suit take over and deal with the cleanup while I ran scenarios, but it was remarkably easy to divide my focus. So while I did all that, and mechanically ate and pounded out another pint of spunk, most of my brain was running scenarios about how this might play out.

Would he freak? Would he convince himself he'd misremembered my true size? Would he be disturbingly into it? I mean, I'd put on significant height and muscle, not to mention dick, in the last few weeks, and anyone would notice and be alarmed, much less someone who paid so much attention to my body last time he saw it. I looked like I'd hit puberty again and worked out for a few years. He was totally going to notice, and he may or may not be into it, but he'd probably be freaked out by it no matter what, and then our little connection would sputter out, and then ---

Mark, you are experiencing panic. Shall I adjust your levels?

....and he'd leave and hate me and call the cops and then I'd be stuck in a lab and then...

..........

You should be back to your normal state now.

Fuck, the AI had adjusted my brain chemicals. I wanted to be mad about that, but really, I'd needed it. I could think more clearly.

"I'm just going to tell him," I announced.

Mark, that is not an advisable course of action. Your modifications could draw unwanted attention if he reacts in a hostile or fearful manner and alerts authorities. We have not yet completed the steps needed to support a cover story.

Yeah, but you know what? I care what he thinks. I like him a lot, and if he likes me, he's going to have to be okay with this.

There is another option. Earlier, Devon absorbed some of your excess nanite waste material; I was able to use that to get additional feedback. By now, that material would have been expelled; however, we can replenish it. That will allow me to monitor his reaction more thoroughly and determine whether he poses a threat to you due to fear or agitation.

Wait, how do you have a baseline for him?

You engaged in multiple rounds of sexual activity, during which I assisted in reading his body language and other internal responses and guiding you to appropriate responses.

So you basically helped me get in sync with him?

That is essentially accurate, though my function was mainly to heighten the experience by drawing your attention to his reactions, rather than directly manipulating your physical response.

And here I thought I'd been an attentive lover on my own terms.

Your excess genital fluids have been stored for some time, since we determined it was unwise for you to continue consuming them. I have been storing them in the refrigerator, pending further analysis. Any nanite material within would be in a suspended state, but would reactivate within the body and under a mild electrical charge. From that point, we have approximately 44 hours of viability during which time I can use them to monitor Devon. Remember, they are tuned to your own body, not his, and the minor physical variations will render them impermanent.

So they'll go away on their own -- this is just to make sure he doesn't freak, or notify me if he freaks out and poses a threat.

If those are the parameters you set, then yes. They pose no threat to him on their own.

Do it, I thought.

Very well. We have sufficient time to prepare a solution before Devon arrives. You need to ensure he drinks it prior to revealing your changes.
 
* * *

I was pulling on my shirt -- a very large shirt -- when Devon pulled up.

ME: I left you a surprise. Just come in and come downstairs.
DEVON: What kind of surprise?
ME: You'll see. When you get there, drink the smoothie on the table and put on the blindfold.
DEVON: what kinda kinky shit you got going buddy
ME: Trust me. I've been busy. And you've been traveling. The smoothie will give you plenty of energy for tonight.
DEVON: damn boy ok

I felt like a little kid again, cramming my huge body into the back room with the door closed. The place was a spotless as it could be, and I'd mixed up a pitcher of a variation of my own nutritional supplements -- and laced it with the nanites we'd centrifuged out of my spunk samples. I hadn't lied, he would be energized from the contents, but it would also leave him with a lingering bit of my suit material in his body, so the AI could make sure all was well.

Upstairs, the door opened and closed again.

"Hey man, you here?"

ME: Yup, come on down and drink the smoothie

"You better not jump out at me. I'm not into that horror movie bullshit!" he laughed. Down the stairs now, the fourth stair creaking as usual.

"Strawberry-banana smoothie? Fine, Mister Mysterious. Better not get a brain freeze!" He said, and drank deeply. I knew these shakes were particularly tasty, and that he loved banana flavor. Plus it helped disguise the chemical aftertaste a bit and mask the slightly mucous-like quality the nanite stuff had. As he finished it off, he slipped the blindfold over his eyes, a broad smile on his lips.

"Alright, man, I'm ready."


"Don't take off the blindfold just yet," I said. "You know I've been on an extreme training regimen."

"Looking fine, last I saw."

"Well, it's been a bit more involved than I let on. I've....really bulked up, and I didn't want to shock you with the changes I've been through."

"You got all muscl-y for me? I'm down with that. Actually, you sound a little different too...." he said, his excited smile beginning to shift to a questioning expression.

"I look quite a bit different now."

"Did you get a tattoo or something? Implants? Not steroids I hope."

"....no." I stepped out. "Promise not to freak."

"I won't freak. Well maybe I will if you don't let me take this blindfold off..."

With that, he shucked his blindfold.


* * *

Devon couldn't believe his eyes when the bashful, sexy hunk stepped into the light.

Over six feet tall, his boyfriend now looked like a competitor in a muscle contest, or a photoshopped cover boy for a workout magazine. Only his face seemed the same, and that was set atop a much thicker neck. His t-shirt was tight in all the right places, for someone a little smaller than him; it was practically obscene and incredibly hot, how it fit his contours and bulges. And down below, the workout shorts, meant to be loose, were snug around his meaty thighs, and his crotch was so stuffed it looked fake...until it twitched. And the scent of his body could faintly be tasted and smelled. If nothing else, that was the smell he knew, and it was like opening a Christmas present. It made him feel excited just seeing the paper, before the first tear.

Jesus, the boy had nearly doubled in size and after seeing what the kid had been packing before, it seemed he hadn't just muscled up or grown a few inches in height.

"How.....what did..." Not his finest response.

"Sit first," Mark said. Devon complied; he hadn't realized he'd stood up.

"You have to promise me you won't tell ANYONE what I"m about to tell you." Devon nodded, marveling at how aesthetically perfect Mark now appeared. His face was still slightly more "cute" rather than "hot" -- in fact, he would probably be considered a bit plain and boring, were it not for the intelligent sparkle in his eye. But the body attached to it was astounding.

Mark sat opposite him at the table, and began, haltingly, to fill him in on the story.

* * *

I gave Devon the abbreviated version: that I'd used my considerable brains to build a transparent body suit, and hacked together an AI programmed to help me integrate with the super-suit I'd built. And then the AI had taken a few liberties based on my dreams, fantasies, and browser history, and had begun helping me build my body to my ideal. (I omitted specific details about the AI, and hoped he wouldn't pry too much -- I especially didn't mention the fact that it was taking control while I slept or had prevented me from altering the program. But I mentioned that it was building to a model in my dreams rather than a real person.

He had loads of questions -- smart ones, I realized, and it dawned on me that I'd underestimated him. Whether it was specifics about the supplements or about the training program, he seemed to understand a fair bit of it. And he asked some tough questions about the AI process, which I tried to answer carefully.

Mark, Devon's reaction is excitement rather than fear. I detect curiosity and arousal. His questions indicate a higher level of education and interest in physical sciences than he has previously revealed. I do not believe he expects to betray your trust.

Well that was a huge relief.

"I want to see all these supplements you're on, and you can show me the exercises," he said. "I mean, damn, you went from cute to hunk to amazing. You look like a pro model or athlete or something!"

"That's not ....the only fantasy that I've been working toward," I said. Devon immediately looked at my shorts.

"Oh rrreeaallly," he purred. "I'm almost afraid to ask."

"It's kind of extreme," I confessed.

"Dude," he said. "You are the hottest think I have seen, and I just came from the islands. Lots a pretty people there, but not great for conversation. I fucking LOVE your brains and this is fucking AMAZING what you did." His eyes were misty with lust, maybe more?

"okay" I said. Hell, there wouldn't be any chance of hiding it anyway, not once it got hard. So I simply stood up, and flexed my dick a bit as it rapidly lengthened along my right thigh, popping right out my jock and racing down my leg. Then it kept going, arcing upward and pushing aside the workout shorts as the big balls worked their way out of my pouch and dropped a solid 8 inches down. Still it kept going, as Devon's jaw dropped and the beastly appendage shot upwards and upwards, quickly passing a foot, then more, and more, until the gigantic thing sat between my pecs. I was strikingly hard and it was taking all my effort to keep my shit together.

"no fucking way," he said. "that cannot be a real thing on your body"

"It's real. It's actually kind of awkward," I admitted. "This is the part where things got out of hand."

"You think?"

"Fuck, I know it's too big, I've turned myself into a freak. I never wanted to be this big, it was just a fantasy, it was the AI misunderstanding that just fantasizing isn't the same as wanting..."

I looked up again, seeking understanding in his eyes...and didn't find what I expected.

What I found was abject lust.


"Dude, it's fucking beautiful."
 
The long-awaited return! Very good addition.

I have a feeling that Devon is going to ask - no, insist - that he be put on the same regimen that Mark's on. Or he'll push Mark even further. Or both.

Also, it's extremely funny that the main thing the AI got out of Devon's response was his "interest in the physical sciences".
 
It`s going to be quite a night for poor Devon me thinks. I know the saying about having eyes bigger than your stomach. I guess it could be a case of mistaken anatomy lol.
Loving it and very much looking froward to reading the next update.
Cheers
 
Devon reached out hesitantly, his eyes seeking my permission. I nodded cautiously.

His hand was warm and I blurped up a little pre.

"It's so warm," he said. "No, it's hot."

"It's huge," I whispered. "Way bigger than I meant to be."

His hand gently felt around it, tracing a vein to the base as he looked on in wonder.

"It's amazing. You're a fucking genius, man."

"Devon, I'm too big. What am I supposed to do with this?"

"I have WAY too many ideas."

"Do any of them involve this thing going into you?"

He blushed, and pulled his hand, regretfully, away. Which was probably best since I'd have nutted all over him if he'd been there a few seconds more. Still, it bobbed between us like an unfinished conversation.

"Well, not all of it, that's for sure," he chuckled. "It must feel amazing though. It's just as silky smooth and perfect as it was before. Just....so much more of it."

"too much," I said. "It was a fantasy, having a huge cock. Not remotely a practical choice. That's the problem. The AI couldn't tell what I wanted wasn't necessarily what I fantasized about until it was too late."

"You are a little extreme. But I told you, Mark. I'm into YOU. The body is amazing and the dick's beyond belief, but you're a real smart guy and I find that super attractive. If this all went away tomorrow, you'd still be the cute, smart guy I was looking at all summer."

I'm utterly sure that I have ZERO poker face, so I'm equally sure he saw my reaction for what it was. Yeah, I fell pretty hard. It was exactly what I needed to hear. I grabbed him -- he was surprisingly light and pliant -- and kissed him deeply.

Oh yeah, he was into it, and leaned in to hold me tight.

My giant schlong was painfully caught between our torsos, pushed between his lean fitness and my bulging pecs. Already slippery, it burped up more pre, and the smell began to permeate the space. Our shirts were quickly damp.

"Do you want to see what we can do with this monster you've created?" he asked, husky-voiced.

"....yeah"

* * *

We had lots of fun with my new 18-inch toy, but my favorite part was sucking it while he fucked me senseless. It took very little thought to control the friction and resistance in my ass, as it happened, and that really helped, because I wasn't really using my brain much for that stretch, and Devon wasn't small. I milked him so thoroughly once that he blacked out for about five minutes which was scary, but he was okay and ready for more.

Four hours later, we were finally mostly sated, and had to break to eat something anyway. I'd essentially hit the snooze button on the AI at one point, when it interrupted the delicious rhythm of being enthusiastically fucked by my boyfriend, but it wasn't long before it reminded me again.

Mark, you must stay on schedule for the eating at least, or you risk destabilizing your system. You also need to rehydrate.

"You know," Devon said, "the freakiest thing is that you don't sweat, but you smell amazing."

I took a sniff. "I mostly just smell you," I smiled.

"You should, I think I came about five times all over you. But man, you were ridiculous," he laughed. "Not only were we crazy in sync, but you're like perfectly lubed and perfectly hard and goddam do you come a lot!"

"Mind over matter, I suppose," I chuckled.

After we ate, Devon watched me go through my workout. He was idly stroking his own dick, thoughtfully, and looking at me with hungry eyes. He was still recovering from travel and an epic fuck.

"Man I'm getting tired and thirsty watching you go through your paces. I'd be exhausted!"

"This is actually light compared to the past few weeks. Mostly it's to keep things stable, and keep my flexibility up." I opted to show off again, locking my legs behind my head while my dick was momentarily flaccid.

"whoa" he said. "Could you always do that?"

"Yeah, I was scrawny and kinda lean, remember? Half of what I just did was to keep flexible."

I grabbed some protein shake from the fridge; Devon declined the offer of one for himself.

"So," he said. "What's next for us?"

"There's an Us?"

"Yeah, three of us -- both of you, and me."

He laughed at my quizzical expression. "Oh, man, you're a hoot. But I wasn't talking about Junior there--" he gestured at my pouch. "I was talking about your AI suit thingie. I mean, can you even take it off?"

I frowned. "I don't think so, not right now at least. It was originally supposed to fit like compression gear, but it's kind of part of me now."

"And the AI? Does it...you know... get a say?"

"What? No! No, it's just doing what I told it to, more or less."

He looked at me thoughtfully. "Can you turn it off?"

"I think so -- or at least, I can turn the proactive part off. The subsystems are important parts of my ability to move, especially now that the suit's essentially become my skin."

With a thought, I hardened the outer layer of my shin, and stabbed at it with my fork.

The fork lost, badly.

"Jesus!"

"Yeah, it's all stiff there now, but the fork didn't penetrate the outer layer. But if the whole thing went like that, it would be really tough to move. But if I'm lifting something really heavy, it was supposed to help stabilize me and support me, so it's strong. Almost military armor grade stuff, despite being ultra thin. I don't know it it would stop a knife or a bullet, but it should be strong enough to take part of the blow."

Your suit density is sufficient to block either of those, depending on the size of the bullet, Mark. Your outer layer is quite hard to damage.

"Seriously?" I asked aloud. "Devon, the suit just said it could probably stop a bullet, and definitely a knife."



"Wow. You know you're a fucking superhero now, right?"

"I can't imagine putting this thing into tights," I said.

"I just wish you could put it into me," Devon said, a little wistfully. "I'm versatile, but that thing is a challenge I am just not up to. You ought to put your brains to work solving that problem."

We opted to cuddle on the couch, watching stupid TV shows and just enjoying each other's presence.


But as Devon dozed in my beefy, longer arms, I wondered about what he said.

Huh. Hadn't really thought that through. Nah, I didn't know enough to tinker with his insides.

Mark, is the ability to accommodate your genitals for intercourse with Devon something you find important? I cannot interpret your signals.

"Is it possible?" I thought.

Potentially, though it would require extensive modifications. Your appendage is beyond normal safety limits. I am curious as to why you -- or your subconscious -- selected the size you did.

It just seemed hot. But like I kept saying, it was never the plan.

The original template called for 14.5 inches, but variation in response was impossible to fully predict.

Nice to know it had some limits.

"Suit, do you think it would be possible for Devon to join this particular club?"

If you refer to the option of modifying Devon to accommodate you, not immediately. However, equipping him with a suit of his own may be possible.

Hmm. Let's keep that option on the table, I thought.
 
If Devon gets his own suit, I wonder if it will have its own AI, or if both of them will be controlled by the same AI? Especially if the AI is running both of them, I foresee Mark and Devon will spend large amounts of time interlocked in a continuous paroxysm of sexual pleasure, as the AI coordinates their bodies.

Or if it's the one AI controlling both, I wonder if it will still just be operating for the benefit of Mark - if Devon will wake up to hear the AI telling him, "To help Mark meet his goals, I will be modifying you..." - or if Devon will find himself turned into a kind of sex toy for Mark. Not that Mark would approve of that, but we know the AI tends to go overboard...
 
this is actually exactly one of my fantasies years ago and i cant stop thinking back then how things would change in the future

this read made me drip precum lmao

i love it so much
 
Remember what I said about multitasking?

Once I got the idea into my head, I couldn’t stop thinking about it. How could Devon ever take my immense prong? I ran through dozens of scenarios, but my knowledge simply wasn’t there. I was poking around on the Internet, checking university databases, and so forth.

Mark, I will prepare research for you. We can evaluate options together later.

Seemed reasonable. I delegated the grunt work to the AI, and refocused on other problems.

Devon had to go, sadly. Reality was no fun, but he had to work. For me, getting this body had been my job all summer. But it wouldn’t be long before classes began.

More importantly, I had only a few days before my parents came home. I would have a lot of explaining to do, and their reactions were not going to be so easy to manage. The more I thought about it, the more I worried. The more I worried, the more often the AI — under orders to avoid messing with my brain chemicals without permission — offered to assist in managing my reactions. It wasn’t just the size thing. I mean, they would come back expecting a kid and find this hulking muscle man, and his gay boyfriend. That was a lot of change. I had to come up with options.

One thing in my favor was that I remained damned smart — with a few real blind spots, which seem obvious in retrospect, but I guess that’s human nature for you. My smarts, plus the AI’s raw processing power, meant that I had set up my own financial and legal independence since roughly a week after I turned 18. I had been investing quietly but extremely lucratively, and that had basically paid for my experiments, with a tidy sum growing in the background. I had delegated most of that to the AI, within some boundaries and general instructions I put in place. I could always move out if I needed to. But I loved my folks, and the strain of avoiding them was starting to get to me.

The other lingering issue was my bestie. Phil. I hadn’t seen him all summer, and we had barely spoken or emailed or chatted. I wasn’t sure how much of this was normal high school friendship drift, and how much was a reaction to my coming out. And most of my time had been invested in this project, though Phil was used to me losing myself in research every so often. I felt like a bad friend...and also, I wanted him to be okay with it. I wanted everyone to be cool with my metamorphosis, and I wanted everyone to meet Devon, and find him as cute and smart and funny as I did.

I briefly entertained the idea of using some of the nano material to help monitor or adjust reactions, but the AI needed to have some time to learn the language of each individual before it was able to even monitor effectively, much less do anything about it. My physical intimacy with Devon made that easier. My parents shared some physical traits but probably not enough for safely guessing. Phil, well, he had surprised me by being cool with me anyway.

Plus, it considered it unethical to tinker with others without their permission.

For three days, I drifted on like that, while going about my normal routines. I continued to work out, absorb information about human anatomy and body chemistry, and spend as much time as I could with Devon. I made more arrangements toward my own independence, and I got very lucky with some investments. But I barely left the house, between my need to eat and masturbate every few hours. Only when Devon was occupying my time could I really ignore the relentless demands of my body, and focus fully on him. I was definitely falling in love, and it seemed like he was too. But work kept him busy, with what I suspected were punitively long shifts to make up for his island vacation. We spent two of the three nights together, and I sent him off to work pretty drained the last day, to the point where he was aching and sore. We had tried, unsuccessfully, to see whether he could take any of my dick, but he simply couldn’t. We found other fun, but that put a bit of a damper on things, because he really wanted to try it.

And so did I. Not just because I hoped it would make him as happy as taking him had made me, but because I was wrestling with another decision about my own size..see, the AI had said that I needed a few more days to stabilize. And among other thoughts, I was planning to see whether we could safely reduce this monster to something more manageable.
 
- Hey, suit, got a question.

What is it, Mark?

I want to set some limits now, but I also want to make a few changes before things stabilize.

What did you have in mind?

Primarily? I find my penis unwieldy. It’s too big, and I would prefer it a little smaller.

That is not possible at this time. It is not consistent with primary programming and I am unable to reverse changes at this time.

But it is beyond my original design, which was about 14 inches, correct?

Mark, your statement is accurate but incomplete. Part of what you wished in this phase was to be pushed beyond your comfort zone in pursuit of your goals. Thus, your current overall size and more specifically your genitalia.

But what if I don’t want that?

Once this phase is completed, it will be safe to update the parameters of my programming.

I’d created an AI that was as stubborn as I was. I spent half an hour trying to find some loophole, but to no avail. The irony is many of these things were angles I had foreseen and programmed around, thinking I was clever. It was using my own safeguards to prevent me altering my safeguards.

Mark, if your concern is sexual compatibility with your partner, I may have come up with some options. However, I do not yet have complete data on Devon, nor has my limited interaction within this system provided sufficient opportunity to safely test those options.

Oh. Welll, there was some hope then.

How long do we have for this phase? I wondered, somewhat resigned.

Seven more hours, and then we will need to run some more tests. But I expect that you will be fully stabilized at that time.

Great. And Devon had a day off coming up, so if tomorrow morning went well, I could work out some options with him. I wasn’t sure, but I suspected he might be game.

As for the family and friends I hadn’t seen in a few months...I decided less was more. I would explain it away as a growth spurt and a ton of work finally paying off. I mean, what else could I do? Boys tended to sprout or invest time and effort into their bodies at my age. Maybe it was more extreme than most — shooting up almost a foot and a hundred pounds might be expected over a longer period but hopefully they wouldn’t be too shocked.

We may wish to alter some of your records to disguise your transformation. By making it appear more gradual, you can probably dissuade some questions. I suggest altering the medical information, which I believe is within my parameters. I will store the originals securely.

Somewhat reassured, I spent an hour working with the AI to chase down my data and tweak it a bit. What a shame reality didn’t just shift to accommodate me, but I never minded a bit of work.

I slept soundly that night.
 
Wrt the previous part you posted - I guess the AI does have some kind of ethical programming after all!

And laptoper, I almost laughed out loud at your comment.

Wrt the part just posted now - it's interesting that Mark and the AI seemed to have reach a mutual understanding, at least in that one moment. The AI almost seemed sympathetic to Mark's request, but remained firm as ever in delivering Mark's "wishes".

I know the AI said that once the current phase is completed, its parameters can be updated, but I had kind of hoped this would be multi-phase process that Mark wouldn't be able to opt out of, with the next phase pushing the bounds of believability for a human body (well, aside from the fact that Mark's penis has already broken that bound).

I can't help but hope that maybe the AI has the next phase kick in before Mark can negotiate any changes, or that Mark's request is necessarily constrained by the plan for the next phase (e.g. "In the next phase, we will aim for only a 20% increase in genital size, instead of 50%...) - basically, I'm hoping that Devon has to submit to some intrusive investigations and fairly extensive modifications by the AI in order to accomodate Mark, rather than Mark getting sized down. At least for now...

In any case, good updates.
 
Mark's suit AI is built from several experimental AI programs - specifically from:
- Military hardware AI, specialized in electronic and mechanical integration
- Medical grade responsive monitoring software, including advanced prosthetics
- Learning software from search algorithms
- Learning software from facial recognition
- Stuff built specifically to spoof the Turing test
- Predictive software based on weather prediction modeling
- His own starter kit of subroutines that monitor for violations of Asimov's robotics laws, bolted onto some hacker tools he either built or adapted and has been using for a while

He specifically did not intend to anthropomorphize his creation, which is why he hasn't named it.

For its part, the AI is pretty straightforward about its purpose and goals. The fun (for us) is when the goals and rules bump into each other, or when fundamental flaws get in deep. The AI now, for example, knows that only conscious, waking, deliberately articulated requests should be taken, but it has to complete the already requested actions before incorporating that into its understanding of the world. It is better able to distinguish Mark's daydreams and wet dreams from Mark's conscious requests. What it does with that once this phase is done is something I plan to cover soon....

Mark is very, very clever. But he's also not quite as smart as he thinks he is, and he lacks life experience. He gets distracted and he hasn't really covered all his bases very well. He's confident in his ability to get control of this situation, but he's not had enough practice at life to really understand consequences on a visceral level. Aside from a bad genetic hand (prior to tinkering), and an unwise interview that "outed" him as a genius, he's not had to deal with mistakes much in his life.

The nano weave is made from several previously failed experiments whose originators were not aware of each other. Military and medical and academic sources that had each solved pieces of the puzzle, integrated now through some really innovative AI tech to manage it.
