Chapter 30: Mechanical Tentacles

"Hey, I told you not to touch his ass."

At Sid's scolding, Elize shrugged her shoulders.

"How would they even know if I put it in or not~ Let's just try it~"

Srrrrk-

Elize's tail coiled around my thigh like a snake. Its surface was smooth stainless steel, and it must have had a heating function since it wasn't cold.

Slap-

After slithering up my thigh, her tail gave my buttocks a playful smack. Elize pulled me into a tight embrace and whispered in my ear.

"How about it? Want big sis to develop you~? Your. Ass."

"N-No!"

"Whyyyy~ I heard when guys develop their ass it feels amazing. A pleasure that's on a whole different level from ejaculation... that kind of incredible sensation?"

"I-I don't need anything like that."

I shook my head with a red face. I'm already feeling enough pleasure as it is... I don't want to feel that kind of thing while having my ass developed.

"But big sis wants to do it...hmm?"

Zzzzt-

Just as Elize's tail was about to penetrate my anus while circling around my buttocks.

Beep-

A warning sound rang out and a researcher's voice flowed through, stopping us.

[Anal contact is prohibited. Please cease immediately.]

There must have been cameras monitoring us in the shower room. Thankfully, the research team intervened at just the right moment...

"Why not~ You guys are going to develop him anyway."

[Please cooperate, it's the President's orders.]

At the researcher's restraint, Elize slowly withdrew her tail that she was about to insert into my ass.

"Aw, that's too bad. But are you perverts watching us shower?"

"See? I told you we shouldn't."

Sid, who had been kneading my dick while spraying cold water, soon stopped her mechanical hands.

My erect penis had gone down after being continuously hit with cold water.

To lose an erection while showering with two naked older women... the cold water's effect was impressive.

"Now we'll wash you~ Don't cum, okay~?"

"Y-Yes..."

Squirt-

Elize took body wash from somewhere and poured it over her breasts. The fragrant shampoo slowly dripped down her sensual curves.

Then, she started creating lather by rubbing her breasts against my back.

"Hng-"

A thrilling shiver ran down my spine. I could clearly feel her compressed breasts and slightly bumpy nipples brushing against my sensitive back skin.

"Does it feel good~?"

Elize diligently moved her breasts to create lather. Her tail, also coated in slick body wash, massaged and kneaded around my buttocks.

Being washed by a woman while she held my unseen backside... not being able to predict how Elize would move was starting to excite me.

When Elize started lathering, Sid also coated her mechanical hands with body wash as if she couldn't lose.

Her hands seemed immune to moisture and foreign substances despite being mechanical.

Whirrrrr-

Then, Sid's fingers moved at a speed invisible to the eye, fluttering like a hummingbird's wings while flowing elegantly like playing piano.

"Oh my. Sid. That's your masturbation mode isn't it. You're going to wash him with that?"

"Shut up."

Sid dismissed Elize's words and brought her flashily moving mechanical hands close to my skin.

"Ngggh...."

When her hands touched my thighs, incredible vibrations transferred to my skin. The impurities on my skin surface melted away like being massaged by a machine.

It felt like all the oil and grime in each pore was being washed away.

Whirrrrr-

Sid's mechanical hands swept across my skin like scaling, leaving my body glowing with reddened skin.

Though the strong stimulation made my skin sensitive and slightly stinging, Sid's mechanical hands were very precise and accurate, not causing any additional pain.

I gulped as I watched her mechanical hands glide across my skin.

'Sid masturbates with that...?'

It seemed like it would be incredible to stimulate places like the clitoris with such powerful vibrations and sensations. The response was amazing when I licked Joo-young's there.

I slightly tensed my penis while imagining Sid moaning. For a moment, I even wondered what would happen if those mechanical hands stimulated my glans.

'No no.'

I shook my head vigorously to stop the naughty thoughts. Getting attacked on the glans with that would probably cause more pain than pleasure.

Anyway, since researchers were watching through cameras and such, there was no further sexual stimulation. I couldn't even get erect since I was continuously being hit with cold water..

After my body washing was complete, Elize and Sid also cleaned themselves thoroughly before leaving the shower room.

Whoosh-

When we exited through the opposite side we entered, strong warm air blew and instantly dried our entire bodies.

Then the three of us entered the disinfection chamber. It was a space sealed off by steel walls.

[Please close your eyes.]

Psssh-

With the guidance, strange particles rained down on us as the ceiling opened.

Poof-

In an instant, the three of us looked like fried food coated in flour.

"..."

"What's this after we just washed~"

"Shit."

Then, dozens or hundreds of nozzles protruded from the steel walls and shot unknown liquid at us.

Swoosh-

It felt like being naked in a car wash with liquid spraying from all directions. The liquid with quite strong pressure worked its way into every nook and cranny of my body.

"Eek!"

This water stream even attacked my ass like a bidet. I thrashed around trying to dodge the water streams assaulting from all directions.

The fierce streams attacking my whole body soon subsided. Thanks to that all the white particles covering us were washed away, but now we looked like drowned rats soaked to the bone.

"..."

"They're treating us too roughly~"

We experienced something similar in the sterilization chamber after leaving the disinfection chamber.

Water filled up the completely sealed space and we were soon trapped underwater, flailing around.

Fortunately, air supply nozzles came down from the ceiling so we could breathe through those.

When we emerged from the sterilization chamber, the researcher we saw earlier greeted us with clothes to change into.

"Good work. Now we'll move to the laboratory."

*

"P-Please save me..!"

Glass walls sealed on all sides. I frantically pounded on the wall while trapped naked inside.

Bang- Bang-

Though I hit the reinforced glass wall as hard as I could, my tiny fists couldn't even make a dent.

After thrashing and pounding on the walls for a while, I finally slumped down. Being trapped in the glass walls itself wasn't so bad.

But the problem was that this glass enclosure was placed right in the middle of a huge laboratory.

Because of that, the many staff stationed in the lab would glance at my completely naked form as they walked by.

There were many pretty female researchers among them, who would smile sweetly or snicker while looking at my lower body as they passed.

All I could do was hurriedly cover my penis with my hands each time. This kind of wide-area humiliation play... I just can't take it...

"Don't worry~ We're watching over you~"

Elize waved from her chair opposite the glass wall. Sid also silently glared at me with crossed arms.

Though they're supposed to be protectors, they're not very reassuring. Yuria won't even answer when called. What's going on....

As I was crouching in the glass enclosure, suddenly the lab's atmosphere completely changed and the busy researchers gathered in line.

'What's with the sudden change?'

I stood up and looked around questioningly. Soon, a figure appeared from far away.

Click- Click-

A woman confidently strode through the researchers in high heels.

Braided bun with ash gray hair neatly tied up. The so-called saber hairstyle.

Black stockings and heels visible under her pure white gown. The round glasses she wore made her intellectual appearance even colder and more dignified.

She was similar in some ways to Yoon Joo-young who took my virginity, but unlike Joo-young who always looked tired from work, this woman seemed very confident and composed.

The researchers all bowed their heads to greet her.

"Welcome, Director."

"Yes. Is this him?"

After handing her bag and documents to the researchers, she stood proudly in front of my glass enclosure.

I crouched down again trying to cover my lower body from her piercing gaze.

"Yes. He's the pure-blood human brought in through brokers."

At the word brokers, the woman glanced at Elize and Sid lounging in chairs.

"Brokers? But why let them into the lab?"

"They're technically guardians. It was Ms. Lancaster's orders."

"...Guardians, I see. Alright. Was he washed properly?"

"Yes. After washing and sterilization, he's been placed in the sterile chamber."

"How fussy. Fine. Start up Uroboros."

"Yes."

Beep-

At the woman who seemed to be the head researcher's command, the researchers busily moved to operate some machine.

As they manipulated something, mechanical tentacles that seemed alive rose from the floor inside the glass wall. Those tentacles slowly approached me like snakes crawling along the ground.

Sssss-

"U-Ugh."

I tried to back away from the mechanical tentacles, but there was limited space to escape in the not-so-large glass enclosure.

Whish-

The mechanical tentacles instantly grabbed my wrists and ankles. They lifted me up into an X shape before bringing me close to the glass wall where the woman stood.

"L-Let me go!"

I tried twisting my body while hanging from the tentacles, but they only tightened their grip on my limbs more. When I violently shook and resisted, the woman spoke indifferently.

"Don't worry. It won't hurt."

The woman removed her glasses. Then she came even closer to the glass wall and spoke while closely examining my body.

"He really is a pure-blood human. The detailed examination is already done. Just need to collect semen?"

"Yes, Director. We've saved up as much semen as possible for accurate testing. However, the President ordered not to touch the anus during semen collection. She said she would do that personally..."

At the researcher's words, the woman called Director snickered and waved her hand.

"That sister's tastes, really. Alright."

She then looked at me with pitying eyes and spoke.

"Too bad for you. You might've been better off with me. The President can be quite rough."

"?"

I could only tilt my head at the incomprehensible words. The woman smirked and opened her mouth.

"Heh. That's how it is. Shame but can't be helped. We'll just proceed with semen collection for now. Gloves."

When she held out her hand, a nearby researcher handed her latex medical gloves. She skillfully put the gloves on her hands.

Snap-

After clenching and unclenching her gloved hands a couple times, she looked at me with gray eyes and calmly declared.

"Good. Then let's begin semen extraction. We won't leave a single drop of sperm in those balls. Uroboros."

Whirr-

At her words, the mechanical tentacles binding me slowly began to move.
