We probably left the church around 10 PM, so it must be about 1 AM right now.

It was already too late to go looking for some fap material and start jerking off.

We arranged for the interstellar planet federation’s space military flagship, Durangurdasil, to take us back to our original planet.

Lucia could have warped us back with her power, but I wanted to enjoy a little spaceship journey for about an hour since we had the chance.

At my request, we borrowed a room in the zero-gravity area.

I’d been running around the ship earlier and felt like I hadn’t gotten enough of the whole "space" vibe.

I was floating in the room with Lucia.

The last surviving alien civilization loli, Mirai, was being held by mechanical arms near the wall.

"Lucia, your hair is spreading out."

Because of zero gravity, her unbound silver hair was drifting around like tree roots.

"Masharu’s dick hair is also... huh?"

"Huh?"

In zero gravity my pubic hair should be floating too... but it wasn’t.

Right, it got burned off by Darkness Fire.

"It looks cuter now."

"Ehh. I liked it bushy..."

While Lucia and I were enjoying the zero-gravity floaty swimming for a while, the door opened.

At the entrance stood a silver-bodied mecha girl, softly reflecting the interior lights.

"Sorry to keep you waiting. The humanoid android is complete."

It looked like Dura-san had properly scanned the image in my head—she was exactly the kind of mecha girl I’d imagined.

Not some half-assed "mecha girl" with a few mechanical parts stuck on a beautiful girl’s head, but a full silver body.

Thanks to the end of the battle, Durangurdasil could focus fully on android production, so the quality was high.

On both sides of her head were the signature huge twintails of a mecha girl, extending down to just below her waist.

The parts around her hips flared out like a skirt, and there were gaps at the joints.

Their civilization’s technology could probably make something much closer to a human, but it seemed they followed my mental image.

Her face had inorganic, glass-like eyes.

She had no nose or mouth; instead, the streamlined face plate had subtle rises and depressions that suggested a nose and a mouth.

If it was exactly as I imagined, removing the chest plate would reveal raw, fleshy breasts, and removing the hard high-leg leotard-like crotch plate would reveal a perfectly human pussy and asshole, but...

I felt too embarrassed to ask.

"So, uh... what about the pussy?"

"By changing the composition of the biological parts in real time, it can adapt to the shape of the inserter’s penis and provide the highest possible pleasure."

I see. I thought I was just muttering to myself, but she heard me.

"Then, we will now begin semen collection."

"Huh?"

Shhhk.

Dura-san’s crotch plate opened, revealing her pussy.

It really looked like a human vagina, not mechanical.

Naturally there was no hair, and a clean, straight slit ran down it.

As I watched, the vertical slit parted on its own, revealing everything—labia minora, labia majora, vaginal opening, hymen, clitoris, urethra—in textbook-perfect clarity, like something you’d want in a sex education book.

Grab!

Dura-san’s twintails extended and grabbed my waist. Since I was floating in zero gravity, I couldn’t dodge.

"Come on, please insert and ejaculate."

"Eh? Eh? Why?!"

"Mirai emerged from the culture fluid, so she will die from malnutrition if left like this. She needs nutritional supplementation."

"Eh?"

"There is no other ingestible nutrition for life forms on this ship. I will collect your semen with my pussy, process it into an easily absorbable form for Mirai, and feed it to her as breast milk."

Gyyyiiiin.

The twintails contracted, pulling me toward Dura-san.

"H-hey, Lucia! Don’t just watch, help me!"

"I don’t sense any malice, and Masharu... you’re not actually hating this from the bottom of your heart..."

"W-wait..."

Was I seriously about to get raped by a mecha girl?

But I wasn’t hard, so I should be fine.

Gugugugu...

Eh? Why the hell am I getting hard on my own?!

Ugh... It was a massive, vein-popping super erection.

Twitch, twitch twitch.

The spongy tissue throbbed angrily from the pressure of swelling.

"I have transmitted forced erection brainwaves and aphrodisiac brainwaves."

"Forced erection brainwaves and aphrodisiac brainwaves?!"

Ugh...

Aah!

I felt like I’d already cum—thick precum overflowed, instantly coating my entire shaft in clear liquid.

"S-stop it..."

"I am a safe pussy with no risk of pregnancy. Please use me as an onahole however your sexual desire dictates. Your masturbation will save Mirai."

Plop...

The glans touched the entrance of Dura-san’s mechanical pussy.

Despite the sensitive tip making contact, there was no ticklish hesitation at all. My cock trembled with anticipation for the insertion pleasure to come.

Thump, thump, thump!

My heart was pounding as hard as the first time I bought an onahole online and opened the cardboard box.

This was super-science onahole technology!

But... I had to resist.

I swore I’d give my pussy virginity to Lucia!

"Stop! Even if it’s a mechanical pussy, it’s still a pussy! Stop!"

If I hadn’t gained all that sexual experience since coming to this other world, I would have given in long ago.

But I had experience with Iria, Ana-san, Ifelasuki, the kemololi, Rafilia-san, and Lucia... I had built up plenty of erotic memories with all of them. I was also supposed to do tons of erotic stuff with Fullru and Letree-san in the future.

My sex warrior power had gone up too!

There was no way I’d let myself be one-sidedly milked by super-science onahole technology!

Even though I was fired up, it was hard to move freely in zero gravity.

"Lucia, help me!"

"B-but... Masharu, you’re hard..."

Khh... Was it because of the scientific censorship on Lucia? Did she not understand the meaning of "forced erection brainwaves"?

"My first pussy insertion has to be with Lucia!"

"...!"

"Since coming to this other world, I’ve put it in lots of girls’ asses and cum. But I’ve never once put it in a pussy. My first time has to be with Lucia! Lucia’s defense is so high you can’t even break your own hymen, so you’ve never felt good with a pussy! That’s why I don’t want to feel good with a pussy by myself! I want to cum together with Lucia someday!"

"Masharu!"

Grab!

Lucia teleported next to me and seized Dura-san’s twintail tentacles.

"Let go. I’m not handing over Masharu’s pussy virginity."

"...! However, Masharu’s semen is indispensable for providing nutrition to Mirai. The future of our civilization is at stake. No matter how much of a true god you may be, I cannot yield."

"Then use the ass."

"Understood."

...As expected of Lucia! She came up with that solution!

Dura-san, who had been so forceful, backed down surprisingly easily.

I was released from the twintail tentacles.

"Female-bodied androids have no need to excrete, so there is no anus. I will now modify the body structure. Please wait a moment."

Saying that, Dura-san floated into an M-shaped spread-leg position. With her right hand she began touching the spot where the anus should be, and with her left hand she played with her pussy. No matter how you looked at it, she was just double-hole masturbating.

Schlick, schlick...

She was probably doing something super-scientific like rearranging molecular structures or changing nanomachine arrays, but it only sounded like masturbation noises. The wetness was probably oil.

Schlick, schlick...

"Haa... haa... nnh..."

Was this mecha girl actually feeling it?

I swam around in zero gravity and watched Dura-san masturbate for a while.

And then—

"Masharu-san. Here is the brand-new, freshly developed anus. Please enjoy."

It really was an anus she had just developed!
