Chapter 4 – Training

When I opened my eyes, it took me a couple of seconds to realize where I was. And something was pressing on my leg that I couldn’t place.

I looked to my right, and when I saw my sister lying beside me, I remembered where I was. Nadia’s legs were spread, and her left leg was draped over my right leg. She was snoring lightly, and her arms were above her head. Because of this, her entire midsection was exposed to just below her breasts.

I tried not to look at my sister’s exposed body and let my mind drift back to our time on Earth to take the edge off it.

I was sitting in my room on my desk chair with my eyes closed. It had been a couple of days since Ethan had taught me how to use the tool between my legs. At the moment, my boxers were around my ankles, and my fist was sliding up and down over my hard dick.

I was visualizing how the sperm shot out of Ethan’s dick, but this image was replaced by Nadia in her blue bikini every now and then. We went to the swimming pool last week, and seeing her in her bikini and how she had filled out in all the right places had struck me hard.

I was trying not to think of it while jerking off, but I simply couldn’t help myself. I concentrated on Ethan’s dick again, but as I tried getting in the zone, there was a soft knock on my door.

“Ay?” Nadia said softly at the other side of the door.

“Just a sec,” I said, feeling panicked about my hard dick and frantically trying to find a way to hide it.

I pulled up my boxers and quickly grabbed a pair of sweatpants from my hamper. I could only hope this would do the trick. I made sure my dickhead was trapped in the waistband of my boxers and that the sweats were covering up everything. A quick glance in the mirror showed that it couldn’t be missed, but it wasn’t too obvious either.

I opened my door, and my dick twitched firmly when I saw Nadia. She was only covered by a towel across her torso. The twitch freed my dick from the waistband, and when I felt it slip and land in my underwear, I quickly oozed onto my desk chair.

“Sup?” I asked as casually as I could.

“I… uhm… can we talk later about, you know… the trip?”

“Of course! I’ll come to your room after my shower, okay?”

“Thanks. I wanna know what you think of it before we decide about it tonight.


And with that, Nadia turned around, and I had to suck in a breath. Her towel was big enough to cover her front, but her butt was exposed this way. Either Nadia didn’t know or didn’t care, but her ass looked like a sculpted statue by Michelangelo himself.

After Nadia closed the door, I jerked myself to a quick orgasm. I didn’t care anymore that I only thought about Nadia in her bikini or showing off her bare ass. I needed to have an orgasm, and I came quicker and harder than I ever did before.

After my shower, I put on a T-shirt and baggy shorts and knocked on my sister’s door. When she opened it, I was glad I opted for the baggy shorts. She was holding a skirt in her hand and was dressed in only a little blue bra with matching hipster panties.

“I… I’ll wait a moment,” I managed to say without choking.

“Don’t be silly! Come in. I’ll be done in a sec.”


“I’m your sister, dummy. Don’t be so overdramatic,” she chuckled as she started zipping up the plaid skirt I liked so much on her.

“I know, but…” I stammered as I walked in and sat on her bed.

“I’ve seen you in way less than this,” she giggled as she slowly put her shirt on and gave me plenty of time to gawk over her lean body.

It was good that I was sitting down because I was rock hard again, even though I shot my load minutes ago.

“That was an accident…” I mumbled.

“I know, I’m just teasing you,” Nadia said as she gave me a quick peck on my cheek and cheerfully walked over to her computer.

“Wh… what do you wanna talk about,” I said as I regained my composure.

“I did some checking, and I need you to see this. I wanna know what you think about it.”

“Okay…” I said questioningly.

“Look. I thought that EEV was a bad company. More like Neoterra evil, if you know what I mean,” she said and paused dramatically.


“Yeah. It’s a Chinese and DRA combined company, and they kill and process a lot of alien lifeforms. They mostly use them for age regeneration and stuff for the wealthy. All very shady.”

“Didn’t know that.”

“Most people don’t. They’re not openly talking about this, obviously. But if you dig a little deeper on them in the FLiN, you find loads of articles about them.”

“But… that isn’t the case with EEV?” I asked, not entirely sure where this was going.

“No. They’re not interested in the other intelligent lifeforms on Aetheria. The biggest animals there are pig-sized, and none of the animals have anything even remotely interesting for us. The EEV only collects water from Aetheria. Well… and natural resources for building and other on-planet stuff, of course. But inside the Aetheria water are extremely useful bacteria, and that’s what they collect and how they fund the operation,” Nadia said excitedly.

“Useful how?”

“The most important use of these bacteria is that they eat our nuclear waste. That waste is turned into hydrogen and a pure form of titanium. Physicists were baffled by this because we didn’t think this was possible. These bacteria can also help with air purification, but their main task is getting rid of that waste.”

Nadia looked smug, and I had to hand it to her. She did a great job looking into this. But I wasn’t sure what she wanted to talk about.

“This doesn’t sound bad,” I said.

“No, it doesn’t sound bad at all. But the main reason I didn’t want to go was because of the idea that we were going to do a lot of shady stuff. Turns out we don’t,” she said, smiling.

“I was only thinking about how we could build our own homes over there and have loads of space and clean air,” I replied, feeling a bit dumb.

“That’s a huge plus. I agree! But the only downside I see now is the fact that there won’t be many teenagers there. I know I don’t mind, but you need to know that we’ll probably be spending a lot of time together over there.”

“Oh. That’s okay. I know there won’t be many kids our age over there, but we won’t be the only ones. Will we?”

“Dunno. According to the FLiN, not a lot of posts are made on the planet,” Nadia said as she looked thoughtfully at me, “but maybe I’m wrong. I just think we need to be on the same page, and we’ll be fine. Don’t you think?”

“Yeah. We’ll be fine, I’m sure!”

Nadia hugged me tightly and gave me another peck on my cheek. She looked at me, and the twinkle in her eyes made my stomach flutter. It was so lovely to feel her close to me, but the conflict of having feelings about my own sister made me loosen the hug and pull back a little.

Nadia thankfully didn’t notice because she said, “Let’s head downstairs. Big family meeting.”

At the start of the family meeting, it was clear everyone was up for it. So, the focus quickly shifted towards the practical aspects of the trip. For the first time in my life, I felt like my parents treated me as an equal. They listened to my concerns and ideas, and we talked about how to handle everything.

We’d have to go to an EEV facility for security and operational training. After completing all the courses successfully and the medical check-up was okay, we’d move into the facility permanently and wait for our launch date there. That would also be the moment when we had to say goodbye to friends and family.

I didn’t have many friends I’d leave behind, but Nadia had to leave her best friend. I could see she was struggling with that when this realization hit. Mom also noticed and offered to help as much as she could with that.

So, on that memorable day, it was decided that our family would become colonists at Aetheria.

“And in this room, you will learn how to use the suits. This is also where our tour ends. If there are any questions, please ask your personal trainer,” the smiling and friendly hostess said to us.

A moment later, her hologram disappeared, and I checked out my brother and sister. Ethan looked a bit bored.

But Nadia looked excitedly at the training room.

“Can’t wait to try out that one,” she said as she pointed.

“Fat chance,” Ethan said, “That’s an exoskeleton suit. You can only use these after you have completed the base course AND have fifty hours of suit time in it. With the schedule we’re supposed to meet, we won’t even be fifty hours on Earth anymore!”

“Stop whining,” Mom said, “We’ve got plenty of time to finish the training. We’ll be divided into age groups. Aidan and Nadia go together and are the only ones in their group. You’ll be with ten others, Ethan, including Rory. I’ll have to do it alone with a couple of strangers and without Dad because he’s in the commander group. So, cheer up and get to work.”

Mom playfully punched Ethan on his shoulder, causing Ethan to smile weakly. Dad grabbed him by his shoulders and said some encouraging words we couldn’t hear. But after that, Ethan smiled again, and we returned to the registration desk.

“Aidan and Nadia?” a friendly-looking young woman asked.

“That’s us,” Nadia said as she raised her hand.

“I’m Senii. Follow me, please.”

We walked behind her toward our training room, and I couldn’t help but notice how good her ass looked in her tight pants. It struck me that I saw it, though. I never looked at a woman’s ass before. Not knowingly, at least.

“Sup?” Nadia asked beside me.


“You look… different, I guess,” she said with a bit of a worried look on her face.

“It’s… I’m just a little nervous, I guess.”

“No need. We will own this training!”

“Damn right, we will!” I replied a little too excitedly.

Senii looked over her shoulder, smiled at us, and said, “Good to see you’re both excited to get started.”

She opened an unmarked door and gestured for us to go in. We were in a small hallway with three doors. One straight ahead and one to each side. Only the door in front of us had a mark, and it read, “Training. Authorized people only beyond this point.” The other two doors were unmarked.

“You can change in those rooms. The HB-ICS you’ll be wearing under the space suits are in there. When you’re done, enter the training room, and we’ll start with a warming up and a light cardio session to see where we’re at.”

Senii opened the door to the training room and left. Nadia and I looked at each other and went into a different room without saying anything.

I entered a small dressing room. On the bench lay a tiny piece of cloth. When I picked it up and pressed it, it grew a little in my hands, and it was clear it was the suit I was supposed to wear. A sign on the wall read, “Suits need to be worn without underwear because of the vital sign readings.”

It was odd to fully undress in a strange environment, but it made sense. So as I stood there naked as the day I was born and flopping my dick from left to right with my hips, which made me giggle, I picked up the suit again. I squeezed it three times, and it grew way bigger in my hands. After this, I could easily fit into it, but it was too big. But autofit would fix that problem.

After I stepped into the HB-ICS, and after autofit kicked in, the suit kept shrinking and was extremely tight around my body. It had short sleeves and short legs. The legs were almost as long as the legs of my boxers, and the arms were just over my shoulders.

As I checked myself in the mirror, I saw how the suit showed it all. You could clearly see my penis pointing toward my left hip. You had to look closely, but even the rim of my dickhead was showing. But it also accentuated my abs and pecs nicely, which made me decide to ignore the visibility of my crotch and just go for it.

Nadia and I opened the door simultaneously. It was immediately apparent that Nadia felt uncomfortable in her outfit. She looked at me and said, “This is a bit… awkward.”

But as she said this, her eyes roamed over my body. And I just had to look, too. Her small breasts were unmistakable and looked magnificent on her. As my eyes went down, I noticed she had a little hint of a six-pack. It wasn’t like Ethan’s or mine, but it looked sexy on her.

But the real prize was between her legs. The HB-ICS was so tight that the two globes of her pussy were showing, accentuating the slit between her legs where a hard dick was supposed to enter her. When the image of my hard penis close to her pussy entered my mind, I felt a stirring in my groin. I checked out Nadia, and her eyes were focused on my crotch.

A suffocating panic washed over me. I was getting a boner, and my sister would watch me grow! I started doing math in my head while I kept looking Nadia in her eyes. She looked a bit puzzled at my crotch, and when our eyes met, she blushed.

“I’m… it’s a bit…” she cleared her throat and smiled weakly.

The math was working, and I guess the panic in my stomach was enough for me to steer clear of a boner. I didn’t want to make this any more awkward than it already was, so I said, “After you,” and opened the door to the training room.

But as Nadia walked into the room in front of me, I noticed how tight the suit was around the back. The fabric was wrapped tight around her ass and pulled between her cheeks enough to give me an excellent view of her fine ass.

This would also mean that my ass was on display, just like hers. But since everything was already pretty much out in the open, I didn’t mind too much. And according to some girls at school that I accidentally overheard, I had a cute butt.

I closed the door behind me and checked the room. There was a cardio device that could turn into several different shapes for different workout types. In another corner were a couple of space suits and a training course that was adjustable into various sorts of terrain and with changeable obstacles.

“Good! The suits fit fine and seem to work,” Senii said as she checked the tablet in her hand.

“Yeah… but aren’t they a bit… revealing?” Nadia asked softly.

“What do you… oh! Don’t worry. There won’t be any more people besides the three of us here. You are brother and sister, so it shouldn’t matter, right? And I’ve seen it all already, and I’ve also signed a confidentiality disclosure.”

“But when we’re out there on Aetheria, there will be more people,” I said, helping my twin sister.

“Oh no! You’ll only wear these under your space suit. And you change into your normal clothes after you go through the airlock cycle.”

“Uhm…” Nadia said.

“Then I guess this is lesson one,” Senii smiled, “From inside the base, you enter a small changing booth. You undress, and from that booth, you enter the decontamination chamber. Behind that chamber, there’s another changing booth where you change into your HB-ICS and the space suit. Then, you’ll enter the airlock, and you’re outside.”

Nadia looked questioningly at Senii and said, “That’s a bit elaborate, isn’t it?”

“The decontamination works both ways. We don’t contaminate the planet yet, and no unknown bacteria can enter the compound. And as a big plus, the inside air stays clean.”

“Naked?” was all I asked.

I couldn’t stop thinking about that bit of her explanation. Maybe I heard it wrong, but I wanted to be sure.

“Naked, yes. That’s the only way we’re sure nothing gets in or out. But don’t worry. Only AI computers check if everything goes well. There are no cameras or humans there. We had to manufacture it this way because in our early design, the inside air was slowly getting contaminated by Aetheria’s molecules, and our equipment couldn’t keep up.”

Senii saw our stunned expressions and smiled warmly at us. She put a hand on Nadia’s shoulder and said, “I promise you’ll get used to it quickly. Before you know it, it’s the most normal thing in the world.”

“In what world?” I snickered

“Touché,” Senii giggled, “let’s just get started with the training, and we’ll talk about this later if you want to, okay?”

“I guess…” Nadia said, still looking a bit weirded out.

“First, the functions of the HB-ICS. It’s short for Human Body Interface Connectivity Suit. It forms the link between you and your suit, so you can make full use of the space suit and will make you feel like you’re not wearing a bulky and hard-to-maneuver suit.”

“So… it tells the suit what I want or something?” I asked, intrigued by the how and what.

“More or less. Your body sends out all kinds of signals. The HB-ICS picks them up, and the CPU in the suit processes them. We just need to tweak the HB-ICS now so it works flawlessly.”

“Cool!” Nadia said.

“Look,” Senii said as she showed us her tablet, “I can see almost everything about you. Heartbeat, blood pressure, muscle tension. I can even see you… uhm… need to pee.”

Senii looked at me with a funny expression on her face and a slight blush on her cheeks, but she didn’t say anything else. I glanced at Nadia, who had a massive grin on her face, and said, “You can’t hide anything from that thing, can you?”

“Nope!” Senii said cheerfully, “Let’s start that workout.”

We did several jumping jacks, burpees, push-ups, and air-ups. After a while, I started sweating, but way later and less than usual during this kind of workout. Senii explained that this had everything to do with the suit’s tech. It kept me cool and changed some of the blood flow.

“Look,” Senii said as we looked at our outlined images on her tablet, “here’s your heart rate, and this shows how you manage to stay cooler.”

“Cool!” Nadia said, clearly impressed.

I was thinking about how this would help you on a foreign planet, so I asked, “Can anyone see this info?”

“No. Just your partner when you’re outside. Or you can explicitly grant access. It’s all a bit personal. I can even see when you need to go to the bathroom and stuff, you know?”

“Can you also change stuff?” Nadia asked.

“Sure! I can make your brother feel hot, for example.”

Senii pressed some buttons on the tablet, and suddenly, I felt like I was on fire.”

“Whoa!” I exclaimed, “Turn that down!”

“Bisque!” Nadia said excitedly. She pointed at another control, “What does this do?”

“It’s a massage function to help with muscle aches. By using this, you can continue for longer when needed. See?”

Senii pressed something again, and a buzz around my shoulder felt nice and comforting.

“Nice!” I said softly.

“And what if I do… this?” Nadia said with a bratty tone.

Before Senii could react, Nadia pressed an icon somewhere near my crotch. A moment later, a buzzing sensation started around my dick.

“Don’t do that!” Senii said sternly, slapped Nadia’s hand away, and quickly switched the setting off.

The buzzing sensation stopped immediately, and I looked questioningly at Senii. She was blushing furiously and stammered, “That’s for… it’s not for you.”

“Sorry,” was Nadia’s guilty-sounding reply as she looked at the floor.

“This isn’t a toy,” Senii said seriously, “you can save your partner’s life when you’re out in the wilderness of a foreign planet. Treat it like that, okay?”

“Yes, of course! I’m sorry,” Nadia replied and glanced at me with a face as if she was caught with her hand in the cookie jar.

The rest of the day was spent tweaking the HB-ICS for both of us. Senii was happy with our progress and said we would start working with the space suit tomorrow.

As we walked back, Nadia was uncommonly quiet. I looked at her and asked, “What’s up? Didn’t you like the training? Was it Senii?”

“Never mind,” Nadia said and looked at the floor.

“Come on! Spit it out,” I pressed.

Nadia stopped and looked at me with an expression that was so serious it almost scared me. She grabbed her ear, something she always did when she was nervous, and said, “I’m sorry about the massage thing…”

After all the other things we did, I honestly forgot about the incident, but apparently, it was still on top of Nadia’s thoughts.

“It’s okay. Really!”

“I shouldn’t have done it without asking you. But I thought maybe something was wrong with your… thingy,” she said, blushing as she looked at my groin.

“My th… why?”

“Because… it looked a lot smaller and softer than when you… when I saw you, you know.”

Now, it was my turn to blush. That short moment in the bathroom made more impact on us than I initially expected.

“It’s, uhm. It’s usually soft, like today,” I said after clearing my throat.

Nadia looked puzzled at me. After a few moments, she asked, “But why was your thingy so… big after your shower?”

“Stop calling it thingy. Makes me feel like a little kid. It’s… uhm. I don’t know if I’m allowed to tell you this.”

“Tell me what?”

“It’s a grownup thing. I heard about it from E… Erik in school,” I said as I realized just in time I was about to expose my brother.

“I won’t tell a soul!” Nadia said as she looked around to see if nobody was around.

I also looked around and saw we were all alone. I ignored my growing dick and said in a conspiratorial tone, “Boys dicks get hard and big in order to make babies.”

Nadia looked like she didn’t believe me and said, “Yeah, right. You were making babies in the shower. Don’t lie to me, Ay!”

“I wasn’t making babies in the shower, dummy!” I said, a little agitated, “As boys grow up, their body prepares them for making babies by getting boners every now and then.”


“That’s when my… dick… gets all swollen and stiff.”


“What do you mean, why?”

“Why does ‘it’ get stiff?” she asked, emphasizing the word it.

As I tried to ignore my massive hardon, I said, “So it can slide into a girl’s… slit.”

Nadia’s eyes widened, and she covered her O-shaped mouth with her hand. I paused dramatically and said, “And when it’s inside, I shoot my sperm. That’s how babies are made.”

My face must’ve looked pretty smug because she asked, “You sure about this?”

“Definitely! Erik’s older brother told him all this, and he made me swear not to rat him out. So, please, keep this to yourself, okay?”

Nadia nodded and was quiet for a moment. Then, her face lit up, and she asked, “But I had my shot moments after I was born, just like every other girl. Will I still get pregnant when you, you know, stick it in?”

This reminded me of the lessons we had in school about this. The pregnancy shot became mandatory after the UN decided it was the only solution for overpopulation. This shot was given to girls right after they were born and ensured they couldn’t get pregnant until they got the shot to reverse the effect. Before this, girls apparently had to take some sort of hormone-based medicine to regulate this. But this was far from watertight, bad for their health, and expensive. So they invented this shot, and the results were almost perfect.  

“I think you need to get your pregnancy shot first. And… I’m your brother, so it’ll be weird if I’d stick it in, don’t you think?”

“You’re right,” she said and blushed brightly again, “I meant it more in a general way, you know? Like.. when a BOY sticks it in.”

“Of course,” I said casually, and we started walking again.

It took a while for my boner to go down, and Nadia was unusually quiet again. Over the next couple of days, she kept stealing glances at my crotch and touched me even more than she usually did. These were simple touches, like when I made her laugh and stuff, and nothing sexual. But to me, they felt electric.
