Irresistible, Chapter 7: Outclassing The Gym

Written by phantomrenegade :: [Saturday, 09 December 2023 19:25] Last updated by :: [Sunday, 10 December 2023 12:47]

The campus gym and sports complex had just been renovated, and the new facilities were top of the line. The school had added another weight room, a brand new Olympic-style pool, and batting cages. Best of all, the new security systems were completely automated, meaning that no one had to be there to scan your student ID. This fact was key to my plan. Since Ren and I were current students, we had two passes that worked. Astrid, however, was no longer a student, so getting her in was the tricky part. My solution was simple: Astrid would use Ren's ID, and I would use mine. Ren would use her speed to jump the turnstile fast enough that the security cameras wouldn't pick her up. I knew there were no cameras inside for privacy reasons, so once we got past the turnstile, we were in the clear. Even if someone were to catch us, it would really just cost us the fee to let Astrid in. Not a ridiculous amount of money, mind you, but being the winter break, I wasn't sure anyone would be around to collect it.

Once we got inside, we first headed for the weight room. As expected, we were completely alone. This was perfect. The girls could really cut loose now.

"Okay, ladies. Let's start with some strength testing. Astrid, have you ever lifted weights before?"

"I tried it to stay in shape, but it didn't really become a habit. Plus, I just never had time while running the shop. I'm guessing I won't have to worry about that now, huh?"

Astrid flexed her arms and smirked. Her arms showed noticeable muscle, like that of a fitness competitor.

"Goddess, that feels so good. I could do that forever."

I looked at the notes I had jotted down.

"Well, let's see. The current world records for weightlifting are set based on the weight of the person and the amount of combined weight used in the clean and jerk and the snatch. Do you know those exercises?"

I heard a snicker as I looked up. Astrid was struggling to hold in laughter.

"What's so- oh, the lift names. Look, I didn't pick them. That's just what they're called. Get the laughter out of your system now so that we can get through this."

Ren looked at Astrid, puzzled.

"What is so humorous about those names?"

Astrid motioned Ren closer and whispered in her ear, still trying not to laugh.

"Oh, I see. It is a joke about sex. That is humorous."

I grumbled under my breath as I pulled up videos of how to do those lifts and showed them to Astrid.

"Do you think you can do those?"

"Oh, yeah, easy."

"Do you need to see those again?"

"No, I… my mind feels sharper now too, like I can remember things better. I can picture myself doing those exercises in my head with perfect form. I think I'll be fine."

"Okay, well, Ren will be here to spot you, just in case. Now, we first need to get your body weight to determine your weight class. There's a scale right over there."

"Should I be naked for this?"

"Um… hoo boy… no, just… just bra and panties will be fine."

"Alright. You'll still get quite a view, stud."

Astrid then began to strip off her new clothes, taking great care not to rip them as she did. She was left in a very lacy black bra and panties set that accentuated her new figure. Finally, she switched out of her Goth boots and into a pair of black and pink tennis shoes.

"Okay, so, how do I look?"

"I think you look amazing, Astrid. I would very much enjoy having sexual activities with you again right now."

"I hate to say it, but cool it, you two. We're here for a purpose, remember? Now, let's get your weight, Astrid."

Astrid stepped onto the scale, which finally settled on one hundred forty pounds.

"Okay, so that's… sixty-three point five kilos. Alright, now, let's see what happens in the testing."

We all walked over to the free weight area and set about getting Astrid ready for the test. Knowing Astrid could easily lift me, I decided to start her off with the world records for women of her size: two hundred sixty pounds for the snatch and three hundred twenty pounds for the clean and jerk. In seconds, Ren had added the appropriate weights to the bars we had selected. Astrid stepped up to the lighter bar.

"So, how long do I have to hold this over my head?"

"Until I say so. I think it has to be at least fifteen seconds."

"Okay, that sounds doable. Let's do this."

Astrid assumed the appropriate position, grabbed the bar, and lifted it off the ground like it was nothing.

"I thought this was supposed to be the world record? This feels like nothing!"

"Wow… that is, in fact, the world record for women in your weight category. Is it really that light to you?"

Astrid shifted her hands to hold the weight with one arm.

"It still feels like nothing! Goddess, I love being fucking STRONG! Add more weight! I need more!"

Okay, Astrid's getting really into this.

"Hmmm… Okay- you can put that down now, Astrid- let's set up the bar for… five hundred twenty pounds?"

"Just double? C'mon, give me a fucking challenge!"

"Well, um… hold on a second."

I ran some calculations, and instructed Ren to set the bars up for two thousand pounds. These new bars were supposed to be rated for up to five tons thanks to a new carbon nanotube infusion in the tungsten steel. I just hoped they would hold, because Astrid was grinning so wide, I thought her head might come off.

"Okay, so, one fucking ton for the snatch? Is that all?"

"You really think you can do it, Astrid?"

"Fuck yes! Just watch me, stud."

With that, Astrid put one hand on the bar and cleanly lifted it over her head.

"Okay, I can feel a little something from this, but it's still so fucking easy! More weight!"

I noticed a faint shine between Astrid's legs. She really was getting off on her own strength. I tried to calm the swelling in my pants and returned to calculating.

"Ren, I can't believe I'm saying this, but… can you set the bar to fifty-six hundred pounds?"

"Of course, lover. I am enjoying watching Astrid's discovery of her new powers."

"So am I, Ren. So am I."

Ren disappeared and reappeared holding some much larger plates.

"These weights claim to be five hundred pounds. Shall I use them?"

"Oh, that's convenient. Yeah, bring them over. That should make things much easier."

Ren adjusted the weight to the requested amount. The bar looked almost comically oversized at this point, but Astrid was still grinning ear to ear.

"Finally, this looks like a proper challenge for my new super strength! Let's fucking do this!"

Astrid sidled up to the bar and began her lift. This time, the cocky smile was gone, replaced by signs of real effort. Astrid grimaced as she got into the squat position, then began shaking as she powered the bar up above her head with a loud grunt. I counted out fifteen seconds in my head, then nodded for her to release it. Astrid lowered the weight back to the floor with a loud rumble and an impact I could feel from a few feet away.

"That… that was actually fucking hard. Holy shit… did I just lift almost three tons!?"

"Two and a half tons, plus a little change. Think you can go higher?"

"No, not this time. I think that was my limit. How did you hit that number so exactly?"

"Oh, well, I… might have been guessing based on an old tabletop RPG book I read once. It had a really defined strength table and all sorts of measurements of a character's strength. I guess it must be pretty accurate."

Ren piped up.

"What is an 'arpeegee'? I am unaware of such a thing."

"Oh, right. It's short for 'roleplaying game'. People create characters and have them explore a world. It's a fun way to get away from reality for a bit, although with you two around, I'm guessing reality is going to be a lot more interesting."

"Ah. Thank you for the explanation. I would like to try one of these games at some point."

"Astrid, you doing okay?"

"Yeah, I'm… great, actually. I guess maybe my body recovers faster now too?"

"Hmmm, could be. Well, I've got the data I need here. Astrid, I can confidently say you're sixty-four times stronger than an average man. I doubt you'll have any trouble with creeps now."

"Yeah, I guess… not… holy shit…"

Ren had added even more weight to the bar, bringing it up to the full five tons it was rated to, and had begun rapidly curling the weight with one arm.

"This does not feel heavy at all. I believe these weights may not be real."

Ren then switched to balancing the weight on one outstretched finger. Astrid and I both came simultaneously from this incredible feat of strength.

"N-n-no, Ren, you're just… impossibly strong…"

"I see. I will put these plates back now."

"Thank you, Ren. Oh, hey, where did you find those massive plates?"

"They were in the locked basement. I simply looked through the lock, unlocked it with a piece of wire, and flew the plates up the stairs."

"Ren, you shouldn't have picked the lock, but those plates did come in handy."

"I am sorry. I will make sure to lock the basement back when we are done here."

In a flash, Ren returned all the plates to their proper places, then returned to the weight area as though she had never left.

"What is the next test for Astrid's new abilities?"

"I think we should go with speed and stamina. For those, we'll need to go to the indoor track."

"Alright! Let's do this!"

We walked down to the indoor track as I planned out my approach. When we got there, I found out that the track had automated time clocks, making things much simpler. I set up the time clock to keep track of lap times, and turned to Ren and Astrid to explain my plan.

"Okay, so, we're going to do two tests here. The first one is simple: the mile run. I've set up the sensors to keep track of your lap times, Astrid. This track is set up so that four laps is a mile. Just run it as fast as you can, okay?"

"Y'know, I always hated the mile run in school. Now, it's going to be a breeze!"

Astrid got into position on the starting blocks. I moved to the computer and set up the starting sequence.





Astrid was off like a blur, tearing around the track. Her first lap time was just under three seconds. Her second was just below that. Her third and fourth were faster still.

"How was that? Did I completely demolish the record?"

"Astrid, your time was eleven point three-three seconds. That's an average top speed of… holy shit… three hundred seventeen miles per hour! That's faster than the fastest production car!"

"Mmmmm, goddess, I just LOVE being super! What's the next test?"

"The next one is a matter of stamina. I want you to run at full speed around the track for as long as you are physically able to keep going. We may also get a new reading on your top speed, since it seems like you were still accelerating during your mile run."

"Okay, so, just keep running until I can't anymore. Got it. I feel like this might take a while."

Astrid got herself into the starting block again. I set up the timing computer to output lap times to a spreadsheet and reset the starting sequence.





Astrid was again just a blur as she began running around and around the track. The computer began outputting lap times to the spreadsheet, just as I had hoped it would. Now, I could use the system to determine Astrid's true top speed, as well as keep an accurate total of laps.

After a couple of hours, Astrid started to slow down. Finally, she came to a stop just in front of where Ren and I were at the computer.

"Well, did you wear yourself out, Astrid?"

"Nope. I mostly got bored. I could have kept going for a lot longer."

"…wow… well, I have a better estimate for your top speed now. Looks like three hundred sixty-two miles per hour is your maximum, which is almost half the speed of sound. That's really incredible."

"Good thing I never bought a car, then. With these powers, it wouldn't even be good for lifting. Being super is so fucking sexy! Did you get any powers from Ren's juices?"

"No, not that I know of. I just got this…"


"Sure, yes."

"That's too bad. Still, you've got two super-powerful, super-sexy girlfriends now who are completely obsessed with your shaft, so that's a nice consolation, isn't it?"

"Heh. I suppose so."

At that, Ren spoke up.

"Does this mean we are all in the relationship with each other?"

"Fuck yeah, goddess! I'm not letting that incredible sex only happen the once."

"This pleases me greatly. I too do not wish for the threesome to stop happening."

"…you girls are going to be the death of me, aren't you?"

"Probably, yeah. So, what's the next test, stud?"

"Well, for that, we'll have to go down to the one of the pools."

"Alright, lead the way."

The pools were also deserted, thankfully. The newer pool had a collapsible bridge separating the Olympic competition section from the diving section, which was much deeper. They had also added a viewing chamber in the deeper end for spectators to watch the divers after they entered the water. This made formulating a plan of testing much simpler.

"Alright, this will be a test of your ability to hold your breath. You'll take a deep breath swim down to the bottom of the deep end and stay there for as long as you can. Once you start to swim up to breathe, that's when I'll stop the stopwatch. Sound good?"

"Sure. So, what's the world record for this?"

"Well… a man held his breath for twenty-four minutes and thirty-seven seconds a few years back."

"Oh, I'm pretty sure I can beat that now. But, uh… what happens if I pass out?"

"Hmmm… Ren, will you do the test with her? We already know you don't really need to breathe, even in space, so if you go down with your lungs full of air, you can make sure Astrid makes it back up."

"I will make sure Astrid is safe."

"Okay, are we all ready?"

"Wait, hold on. Let me slip into something more revealing."

Astrid undid her bra and removed her panties. In a split-second, Ren was also naked. Looking at these two superwomen, I felt my pants become slightly less comfortable.

"Okay, now I'm really ready."

"I am ready as well."

"Okay, you two get in the water. I'll get the stopwatch ready."

I positioned myself on the bleachers near the pool and watched as the girls got into position.

"Whenever you go under, I'll start the time. Make sure you get a good deep breath, okay?"

"I got it, I got it."

I could feel a slight breeze blowing towards the center of the pool as Astrid began to inhale. After about a minute, Astrid and Ren dove underwater. I started the stopwatch and headed for the underwater viewing chamber. As I climbed down the ladder into the chamber, I saw Astrid wave at me. I was amazed that she could see me so clearly, especially in a darker area.

Perhaps her vision has been enhanced too.

As the stopwatch ticked on, Astrid and Ren sat at the bottom of the pool, seemingly content to just wait out the time.

Five minutes.

Ten minutes.

Fifteen minutes.

Twenty minutes.

Twenty-five minutes.

Astrid had, with no training, beaten the world record for holding one's breath underwater. And yet, she continued to sit at the bottom of the pool.

Thirty minutes.

Forty-five minutes.

After an hour, Astrid began swimming to the surface. I stopped the stopwatch and began to climb out of the viewing chamber when I heard a splash. As I emerged, I expected to see Astrid and Ren floating in the pool. What I saw was… nothing. Astrid and Ren were still underwater. Suddenly, a shape underwater began rapidly ascending. As I watched, Astrid leapt out of the water like a dolphin, flying roughly twenty feet into the air before returning to the pool with a small splash. Astrid repeated this feat several more times before finally swimming to the edge of the pool to talk to me.

"I take it you got bored again?"

"Yeah, I wasn't even straining. How long was I underwater?"

"An hour and change."

"I could have gone way longer. Still, did you see those sick flips?"

"They were pretty impressive, yeah. Were you a swimmer before?"

"Nope! But now, I can swim better than a dolphin! Y'know, when I was little, I always wanted to be a mermaid, and now I kind of am! Being super freaking RULES!"

"I'm glad you're having fun. Say, where's Ren?"

The other shape underwater suddenly rocketed out of the water, flying in a graceful arc before landing directly behind where I was standing.

"I am here now."

"Good, good. Now… wait. We have a problem. We don't have any towels."

"Oh, shit, you're right. How are we gonna dry off?"

"I will show you. Please take our clothing somewhere that will not get wet."

Not knowing what Ren was planning, I grabbed the stack of clothes and went to the nearest door. Through the window, I saw Ren become… fuzzy for a second. Astrid then did the same, almost seeming to be out of focus for a second. Ren then motioned for me to return.

When I got back to the girls, they were completely dry. Right then, it clicked what had happened. They had vibrated themselves at high speed, shaking all the water off of their bodies.

"Man, that's such a cool trick! I gotta remember that."

"Thank you. I discovered this method of drying myself on my island. It is very useful."

"I said it before, I'll say it again; I fucking love being super!"

"Here are your clothes, still completely dry."

"Thanks, stud. Now, what's next on the testing plan?"

"The batting cages. I've got a few ideas for tests there."

"Then let's go!"

Astrid got back into her bra and panties, Ren dresses at superspeed, and we were off. We walked down to the batting cages, where I explained my plan for the next test.

"Okay, so, the next test will be reflexes. Astrid, I want you to catch these balls as they're fired towards you. I'm going to set the machine to max speed so it'll really be a challenge. Sound good?"

"Absolutely! Bring it on!"

I walked to the pitching machines as Astrid got into a cage. The pitching machines were quite advanced, allowing one to dial in pitch speeds and firing area. A note on the machine stated not to set the machines above one hundred miles per hour unless you were a "trained professional". I chuckled and set the machine to one hundred twenty. This speed should be a proper test of Astrid's reflexes.

"Okay, Astrid, I'm going to set the machine to fire five shots. These are just for you to get used to the speed, okay? You don't have to try to catch these."

Ren spoke up.

"Astrid, focus your mind. Feel the world around you slow down. You must perceive the world at your speed."

"Okay, I'll try it. I've never been good at this sort of thing, but now I'm fucking SUPER! I can do this."

"Alright, Astrid, here come the test shots."

I pressed the "start" button on the pitching machine and waited.

The first ball fired out of the machine and flew so close to Astrid's head, her pigtails started moving. The ball hit the backstop with a loud THUMP.

The second ball fired was wide left of Astrid, but she seemed to look at where the ball was going as it flew.

The third ball fired was right down the middle, hitting Astrid in the abs with a resounding THWACK. Astrid didn't even flinch.

The fourth ball was wide right. This time, Astrid moved towards the ball as if to block it.

The fifth ball was dead center again. Astrid's hand suddenly shot out and grabbed the ball in mid-air like it had been standing still.

"Look! I caught one! I figured out how to see them coming!"

"Astrid, do you know what the most interesting thing about baseball is?"

"Um… turning off the baseball game?"

"It's the fact that seeing the ball can be next to impossible, and yet people can still hit the really fast pitches. Your reflexes are such that you can now see the balls coming and react to them accordingly."

"Fuck, that's really cool."

"Now, let's make this interesting. Open up the next two cages. You're going to have to run between the cages and catch the balls as they fire, but you won't know where the next pitch is coming from. Ready to give it a shot?"

"Hell yeah!"

I set the pitching machines for one hundred fifty miles per hour and manual triggering. I pulled the remotes together and prepared to fire the cannons.

"Okay, here we go!"

Pitch one went into cage three. Suddenly, Astrid was there with a ball in her hand.

"This is sooooo easy now!"

I sent pitch two to cage one. Again, Astrid caught it.

"Come on, try harder!"

Alright, wiseass.

I fired the next two shots at the same time in cages two and three. Astrid was suddenly in cage three, holding two balls.

"Oh ho ho, trying to trick me? Keep it up. I love a good challenge."

This time, I fired all three at once, hoping she would miss one. Astrid appeared in cage one, holding all three balls with a smirk on her face.

"I think we've proven that I can handle your balls, haven't we?"

"Well, now it's time for the other test: durability. I want you to stand in place and let the balls hit you in the same place repeatedly."

"Have you seen how hard these abs are? These silly balls aren't going to do anything to me."

"I was pretty sure of that, but we don't have anything heavier-duty to throw at you. Plus, I really don't want to actually injure you. I just wanted to see if you had a healing factor, but… I guess your quick recoveries after the previous tests would tend to support that theory."

"Yeah, as hot as it would be to be fucking bulletproof, I don't want to be wrong about that."


At this point, Ren chimed in.

"May I try your ball catching test? It looks enjoyable."

"Uh… sure, Ren. Let me just figure out how to make it more challenging."

I decided on priming all but one of the pitching machines to fire as rapidly as possible. The last machine was left deactivated.

"Okay, Ren, here are the rules: every cage except for cage six will have its pitching machine firing at maximum speed and fire rate. You're not allowed to fly, only run. You are only allowed to carry one ball at a time. You can only deposit balls in cage six. Each machine is primed for ten shots. If a ball hits the ground, the backboard, or you, you lose. Do you understand the rules?"

"Yes. This will be most exciting."

"Okay, start in cage six. I'm firing up the pitching machines. Good luck, Ren."

"Yeah, good luck, goddess! You got this!"

I started the pitching machines and prepared for chaos. The pitching machines began firing wildly, launching ball after ball into each cage. Ren was a blur, but balls were rapidly piling up in cage six. Finally, Ren reappeared in cage six after the machines stopped firing. She hadn't missed a single ball.

"Yeah! Way to go, goddess!"

"Wow, that's really amazing."

"Thank you. The game was most pleasant, although I am unsure how to make it more of a challenge. Now, Astrid, would you like a reward for all of your hard work?"

"Y-yes, goddess. I would love that."

"Then we shall return to the apartment for more sexual activities. This has been a truly glorious day."

After Astrid got redressed, I stopped her for a moment.

"Hey, so, how did your mom take your new… developments?"

"Oh, uh… y'know…"


"Okay, okay. I told her that you, me, and Ren had done the do, and that somehow I had gotten transformed into this. I didn't mention the new powers, and I'm not going to. She seemed to take it okay. I mean, we're witches. You learn to roll with weird shit happening."

"Huh. Well, at least your mom isn't freaked out by all this."

"Yeah, thankfully. I don't have too many friends, so I doubt anyone will suspect a thing. I'd love to hear what those snooty bitches at the Goth club say when they see me now. Actually, I probably can now. Wicked. Now, less talky, more fucky!"

"Right, right. Let's get to the car."

I like where this is going. I love viral super-ness stories.

Hope we get experimentation (doses etc) given the university setting.
