Caveman - Part Six

[tekuno]

Oops, I almost forgot: Make sure you have read part five already before reading this. I commented on part four after posting part five, so four was bumped above five, and the view count for four went way up, so I kind of suspect that a lot of people thought four was a new part, clicked it, discovered it wasn't, and gave up.

If this part seems a little rushed, that's because it is, sort of. I actually wanted to include the next part of the plot -- Joe and Mike getting into the act (technically that's a spoiler, but if you weren't expecting it by now you haven't been paying attention) -- in this post, but it's getting late and I'm too tired to do it well enough, so it will have to wait.

In this case, the wait will be a little longer than usual, probably, because (as mentioned elsewhere) I'm planning to do a full backup of my computer, zap the HD completely, and install the next version of the OS from scratch, and copy my personal files back into my user account. (The current installation has a lot of cruft -- like Java, a.k.a. "security holes held together with duct tape" -- installed, so I want to wipe and start over, and I need the new version for various reasons.) So let's say the next part will be posted by Wednesday, which gives me quite a bit of time to sit and watch progress bars as things copy back and forth.

By the way, is anyone reading OnePunch-Man? If only Saitama was drawn with a build that reflected his strength...

I could learn to understand Swahili by myself
I could even teach it to my good dog, Ralph
I could learn to read you every book up on the shelf; I
Could learn to tell your fortune like the oracle of Delphi

I could learn to tell you every flower by its color
I could learn to swim as fast as Johnny Weissmuller
But I couldn't never learn to get along without you
Don't you run away from me, I sure dig sex

-- Michael Peter Smith, Wonderful World of Sex (usually performed by Steve Goodman)

I spent the next ten minutes hovering near the front door in anticipation. Naturally, the doorbell didn't actually ring until I finally gave up and headed to the kitchen to look at the clock.

When I opened the door, Norris obviously didn't recognize me. I mean, REALLY obviously. His head was tilted downward slightly to look at where my head would have been if he had been coming over a few days earlier, which was now around my belly button. Then he looked up. And further up. He got a very interesting look on his face for a moment, and then squeaked out:

"I-is Mitch-- Mitchell here?" I frowned down at him, and he added "Sir?" I held my frown for a beat longer, but before I could break into laughter he blurted out "I'm, uh, I'm his friend Norris-- I mean, Michael Clemson. He invited me over."

The opportunity was just too good. I gave a growl and tried to look angry -- actually, I could feel that my mouth was involuntarily starting to smile, so probably it was more like a grimace, not that that would have been any more reassuring -- and grabbed his shirt front with one hand, lifted him up until his face was inches from mine, and then heaved him over my shoulder and carried him inside.

I walked through the house to my bedroom with Norris over my shoulder. The whole way, he was sputtering. Oddly, it didn't seem to occur to him to call for help; he kept requesting to be put down, in between "um"s and "er"s. At first I wondered a little, but by the time I reached my bedroom, I understood why Norris wasn't upset -- a lump had formed in the crotch of his pants and was pushing into the back of my enormous rear deltoid.

Well, well -- no wonder Norris hadn't been dating, despite being physically more normal than me. The secret was obvious in retrospect, although he had done a good job of diverting attention from it. And now he was here with me... Since he wasn't able to see my face the way I was holding him, I grinned and grinned and grinned, trying to get it out of my system.

In my bedroom, I composed my face as I pulled Norris off my shoulder and plopped him down on the bed in a sitting position. He almost immediately cupped his hands in his lap, and I tried not to let the grin reappear.

I stepped back to the door and pushed it closed. Then I turned and faced Norris and tried to put on my most impressive frown. It lasted about three seconds, but that was long enough to set Norris gibbering again, so I burst out laughing.

"I really had you going, didn't I?"

"Mitch? Is that... you?! What happened to you?"

"I finally had a growth spurt, Norris. What do you think?"

I leaned over and flexed my arm in front of his face, and he reached out and started feeling it. He just couldn't get enough. I was surprised; when he next spoke he actually had to clear some drool out of the way.

"Geez, you're big! This is incredible!" His hands were stroking all the way from my trapezius to my wrist. He seemed to be particularly enthralled by the texture of the hairs which were beginning to grow on my forearm. He gave a satisfied sigh, and when he spoke again, he was almost talking to himself instead of to me. "So huge... I want this. I want this so bad!"

I cleared my throat, breaking his reverie. "You want this, as in me? Or you want this kind of thing--" I gave an extra flex "--for yourself?"

I felt sorry as soon as I said that. Norris flushed and started to stammer out a non-answer. Merely asking the question put Norris on the spot, which was cruel. Of course, I was pretty sure that the answer to the first question was 'yes', but it was unfair to force him into giving up a secret he had apparently been trying hard to keep.

On the other hand, I was hoping to let him in on a far bigger secret than some piddling little case of closeted sexuality. If he couldn't trust me with his secret, what would that mean for me and my secret? I decided to risk it.

"Well, if the answer to the first part is 'yes', you can have it." And then I grabbed his head and pulled it back, leaned in, and gave him a long, deep kiss. About halfway through, he started kissing back. I felt like doing a fist pump and shouting "yes!", although I settled for "mmmmmm".

When we finally released, Norris was looking at me again, and smiling. In a way, it was the first time he had really had a chance to take a good look at my body. Up until then, he had obviously been trying not to stare. Now he was, so to speak, licensed.

"What did you DO to yourself, Mitch? You're fucking huge!" From Norris, I should explain, the expletive was a mark of unusual force of feeling. Norris almost NEVER swore. In junior high, he had trained himself to use various Victorian and 1950s remarks. We occasionally mocked him for it, although it seemed to help him with his work for the school paper. Unlike his fouler-mouthed peers, he could simply write as he spoke without having to edit or pause to think of synonyms for the sake of expression.

"It's a secret, which I may or may not be willing to tell you. Want to see more?"

"Oh, god, yes!" I had never actually seen anyone lick their lips from lust before.

I took off the shirt first. In a few seconds, Norris was all over me, rubbing my pecs, tweaking my nipples, feeling the bumps of my incredible abs. I knelt down to give him easier access, since he was now so much shorter than I was.

"You're so thick! I don't think anyone has ever been this big! Oh, man!" Norris giggled in shock as I trapped his fingers up to the second knuckle between my pecs, licked my almost-hairless armpits, and climbed on my upper arms and begged me to flex and relax my biceps so he could feel the rise.

I think he came during that last bit. Certainly he calmed down a bit, at least temporarily. We hugged each other and kissed again and again, and I lay back on the bed. He snuggled in, with his head leaning up against one of my massive biceps.

"So, Norris, what do you think?"

"What do I think? I think you're the sexiest thing I've ever seen. I think you're a sex god. I think you're the person I want to spend my life with. Whatever happened to you, I'm glad it was you it happened to. I was always hoping--"

This was getting a little embarrassing, if flattering. I interrupted. "No no, I mean about wanting it for yourself. I don't know if you'll end up as big as me, but you can probably get a lot bigger than you already are."

Norris sat up and gave me a blank look. "What, are they giving away steroids in boxes of Cracker Jacks now?"

"No. It's even weirder than that. But it's a secret. If I tell you, you have to promise not to tell anyone. Not even your parents, or Mike and Joe, or anyone, unless you get permission."

"Secret government weapons testing?"

"Weirder. Do you promise?"

Norris sighed. "I'm not sure."

I grabbed him, and we started making out. I started to get hard. After a while, I pulled away, got out of the bed, and smiled down at Norris. "Time for you to see the other half."

I pulled the jeans down, and Norris groaned in astonishment. Once again, he launched himself from the bed and started exploring my body, this time from the waist down. It ended with the two of us sitting next to each other as he jerked us both off. My gigantic testicles sprayed many times as much cum as his more ordinary equipment, and he groaned again.

"Okay, okay, I promise I'll keep a secret."

"You want to be hung like this, huh?"

Norris blushed. "Not really. But, uh, I don't think I could ever... take something of that size unless I get a lot bigger."

"Take?"

"Up the... you know!"

"Oh!" My turn to blush. I hadn't really thought about the mechanics of sex before, or at least not as they would affect me personally, because there didn't seem to be any chance that it would ever happen to me. Actually, now that he mentioned it, that was probably true. Not too long before, after all, I had knocked down trees and crushed rocks underfoot. My penis might not be quite as sturdy as my feet, but Norris' body wasn't as tough as a tree or a stone, either.

"Okay, then, it's like this..."

We spent the rest of the day hanging out... sort of. Until then, to me, hanging out had involved playing video games, talking, maybe doing some homework if there was nothing else, and eating. Not that we didn't do that sort of thing, too, but we also made out for a couple of hours (not continuously), did some mutual masturbation a few times, and did some rudimentary strength testing -- I converted one of Dad's multipurpose exercise machines into a ball of scrap metal, and tossed it around the back yard, much to Norris' sexual excitement.

At lunch time, Norris was very interested in the super-spam. He tried a small piece and pronounced it boring and difficult to chew, and was astounded when I wolfed down two cylinders in about the time it took for him to finish the sandwich he made. (I was pleased to realize that my appetite wasn't completely gone.)

Towards dinnertime, we discussed practical tactics. As it turned out, bulking up Norris would be easy. His mother had discovered business interests downstate, and had basically dropped him off at home with a wad of cash for food and departed again for the rest of the week. (I thought I smelled Gary's influence in those business interests, although once again I could hardly prove anything.) There was no reason why he couldn't spend the rest of the week at my house.

He headed home to pick up a few things he would need, and came back straining under an enormously overpacked hiking backpack at about 5. I greeted him at the door with a kiss, and carried him and the backpack to my room. Then we set out for Gary's cave.

"...I'm still having trouble believing this, you know."

"Well, then, how do you explain my body?"

"That's the only reason I'm following you through this godawful bug-infested backwoods."

"Tsk. Don't exaggerate; there aren't a lot of bugs here."

"Oh, just--"

At that moment, we came into the clearing which held the cave, and that was enough to silence Norris.

"Whoa!"

"Still think I'm making it up?"

"Well, we haven't seen your caveman yet."

I walked up and banged on the "door", which opened.

"Seeing is believing, right?"

"Right."

We walked down the tunnel hand in hand. At the end, Gary was waiting for us.

"Ah, welcome back, Mitch. This is the test subject you promised me?"

"Yes. He's staying with me for the next few days, so you can monitor him if you like."

"Very good! Er, tell me, do you think you'll be able to find me any more test subjects, or do I only have one chance to experiment? If there are going to be others, then I'd like to try giving this one the same thing you were given, to see if the effects on you were normal or not."

I thought about Joe, and grinned. A chance to bulk up without effort? He'd take it without blinking. "I think I can promise you another, er, test subject in about a week, if you can wait for it."

"Excellent! That will give me a chance to observe the results of this experiment first, so the others will be even better. So, young man, what's your name?"

Norris coughed. "You can call me Norris."

Gary looked perplexed for a moment. "Ah, I see. Blond hair, blue eyes, slim build. 'Black Wind', yes?"

Norris looked shocked. "Well, er, yeah. But how--"

I decided to interrupt. "Gary has an Internet hookup in his head, and his searching seems to be a lot more efficient than Gooble."

Gary laughed. "So, would you like your top shot, Norris?"

"Uh, yes, if that's-- OW!"

The arm with the needle was already retracting by the time Norris looked around.

"Mitchell, I will leave it to you to explain what is happening to Norris. Please come back at about the same time tomorrow so we can see his progress."

"We'll do that. Thank you, Gary!"

Norris and I trekked back to the cave entrance.

"I wouldn't have believed it if I hadn't seen it."

"Well, now you know. Let's head back to the house; you'll probably start getting hungry soon."

"Ugh. More woods."

"Want me to carry you?"

I was joking, expecting Norris to brush the offer aside, but he blushed, and said "Well, uh, if you're offering."

As I raced through the forest with Norris on my back, he said "I had to take the opportunity, since you won't be able to carry me if I get as big as you are."

I shook my head. "Don't you believe it. Remember how I was tossing that machine around before? Even that wasn't difficult. I could probably carry ten or twelve people my size and not notice they were there beyond the pressure on my skin. I'm barely noticing you at all, beyond the touch sensation."

Norris whistled. "Wow. That's a bit much to take in."

"Yep. And you're going to join me, soon."

Nevertheless, when we got back to the house, although Norris got hungry, he only managed one and a half of the cylinders. It was enough food that he was surprised at his own appetite, and took a long time to eat it all, but I managed to eat -- and apparently flash-metabolize -- three of them in the same time. (Apparently, all the sex was undoing whatever Gary's shot had done to me.) On the other hand, though, Norris wasn't starting from a deficit; he was a normal guy.

He had a surprise for me: when he had stopped at home, one of the things he had tossed into his pack was a measuring tape. We had a lot of fun with it, and could now say that my upper arms were a bit over 31 inches around, my waist was 33 (yes, my arms were almost as big around as my waist; it would have looked oddly disproportional if I hadn't been so tall that my arms merely looked large), my thighs were 47 1/2 -- Norris was disappointed that they weren't twice as big as my waist, but I kissed him and said I needed a goal for future workouts -- and my chest was at least 80 inches because the measuring tape wouldn't go all the way around. My cock -- which Norris measured as though he had been given permission to polish the Holy Grail -- turned out to be 18 inches long and 9 inches around at its widest point.

We had a fairly erotic evening, interrupted by time in the bathroom for both of us, unavoidably, which led to another cylinder each for me and Norris, and then we went to sleep, sharing my bed. It was the first time I had ever been grateful for my mother's ostentatious furnishings. Until then, I had always thought a king-size bed was too big for me all by myself, but now it seemed to be all right, and combined with the new-and-improved Norris it was just about perfect.

The next morning, Norris and I talked it over. Both of us were disappointed that his gains were so small compared with mine. But, I pointed out, ejaculation seemed to help stimulate the growth, which gave us a way to possibly accelerate the process.

As a result, the day was basically a long parade of sex. And it did make a difference to Norris; he had 2 cylinders for breakfast, 3 for lunch, and another 3 for dinner. (I had 4 each time.) By the time we reached Gary's cave, he had gained a half-inch in height and 15 pounds -- presumably nearly all muscle and bone -- over the day before. He was now 5' 9" and 171 pounds, and looked pretty good. He wouldn't let me take any other measurements, though, saying that until he looked half as good as me he didn't want to know.

I, on the other hand, had also made some more gains, and looked fantastic. But then, as Norris pointed out, I had already looked fantastic, so it was hardly fair. And we couldn't even tell how fast I was growing; Dad's fancy-pants balance scale (nothing but the best for the weight room he never used!) only went up to 300, and when I stood on Mom's bathroom scale, the dial went around and then stopped with a clunk shortly before hitting the "0" mark again. We knew I was 7' 9", though.

When we went to see Gary -- Norris insisted on riding on my back again, in both directions -- he was relieved that Norris was growing so much more slowly.

"This is what I had expected from you, as well. I still don't know quite why you reacted the way you did."

"Don't worry Gary. If anything, I wish we could make Norris grow like I did. But I'll settle for him being merely the second-biggest guy when we get back to school."

"Hmmmm. I'd still like to find out what the difference is. That sort of growth really ought to have been impossible."

"Well, don't worry too much. We'll bring another guy for you to experiment on in a few days. I'm sure you'll figure it out."

"As you say. Do you need anything else from me?"

"Not at the moment."

Norris was silent nearly the whole way home. As we entered my back yard, he said "I wonder what Gary does to pass the time. It must be lonely out there."

I smiled. "Given his reaction the other day, I think he's spending a lot of time looking at porn. After a few millennia of abstinence, his balls are probably ready to explode."

"If he's as much like you as the two of you look, then you're probably right. How many times did you cum in the last 24 hours?"

"Not as many as I plan to in the next 24, Sweetie."

With that, we fell back into our routine of sex and food and sleep (and bathroom breaks). At that point, our sex life was pretty bland; we both agreed that Norris was probably too fragile to withstand being topped by me, and I was too big for him to comfortably give me a blowjob, so I had to be jacked off. Norris, on the other hand, found that the powerful muscles of my ass were too tight for comfort, as were my hands unless I was very careful, so other than masturbation his only option was pec-fucking -- which was fun, but fairly repetitive.

Over the next day, I managed to increase Norris' appetite to a whole 10 and a half cylinders (while I ate 16), and just before we left we measured him at 5' 10" and 188 pounds -- not bad at all! Gary once again hemmed and hawed over me, and seemed happy with Norris' progress -- or rather, his lack thereof -- and gave us a fresh bag of cylinders, since we were running out.

In fact, the next three days were basically repetitions of that one. Norris never managed 17 pounds in a day again, although he stayed fairly close, and Gary continued to give us more food and the same reinforcements of the same messages.

Even though Norris had grown much more slowly, he was now looking extraordinarily good; especially when you considered that he was only barely 18. When we got back from our final trip to Gary's before Joe returned -- an occasion for which we had asked Gary to fabricate some new clothing for Norris -- he finally consented to some measurements.

We found that he was now 5' 11" and a little over 235 pounds. His upper arms were 18 1/2", and his waist was a wasp-like 27". His chest was now 53 1/2" around, nearly twice his waist size, and his thighs were 26" each, with a 10-inch cock between them. Not bad at all! There wasn't a guy on the school football or wrestling teams who wouldn't trade bodies with him in an instant, including Joe, and I told him so.

Norris' measurements were enough to get me going, and I would have been happy to begin our evening festivities right away, but he insisted on measuring me as well.

To my surprise, although Norris said he had noticed it each day, I had gotten significantly bigger. I had made it to 7' 11", and I now had 35" arms, 52" thighs, and -- Norris improvised with a strip of paper -- a 102" chest, all connected by a waist which was still only 32". At that point, I was so turned on that I picked up Norris and jacked myself off by rubbing my cock along his body (first the center of his back, then along his abs and pecs so he could use his hands on me), and so it was only later that he confirmed that it had grown a bit, too -- 20 inches long and 10 around.

We were having some pillow talk afterwards, and I was appreciating Norris' new baritone voice -- he had been a tenor before the shot -- before heading down to dinner, when my phone chirped. It was a text from Joe:

"Back from the funeral. Busy tonight?"

I showed it to Norris, who grinned. I composed a reply:

"Norris and I have been doing fitness training. Good results. Want to come see?"

This made Norris laugh out loud. The reply came quickly:

"I'll be there after dinner, about an hour from now."

With an hour left, we managed an orgasm each, plus cleanup, plus another meal, plus a bathroom break, before the doorbell rang. By prearranged agreement, Norris answered the door.

"Hey, Joe."

"Norris? What the fuck happened to you? You're huge!"

"You should see Mitch. Come in."

Joe walked in and encountered me. He stared up at me for a while, mouth hanging open. Then he gave a feeble grin.

"I can see something's been going on while I was away. Care to enlighten me?"

Next Part
has a palindromic thread number which is divisible by 3^3 and 2^3. Neat!

Thanks!

Well, the computer is mostly set back up, except for a couple of programs which I don't really need for now. (In fact, it was almost disturbingly easy compared to the last time I had to do anything like this a few years back. Not sure if the programmers have just gotten their acts together or I just know what to look for these days. Maybe a little of both?) But I'm too tired to write now, so nothing more for at least one more day.

...oh, and I came up with another story idea for a multipart, but shortish, story. Needs some thinking before I can write it, though. If I can ever get this song out of my head...
