for Advance Chapter
That afternoon, the sun was just right.
For a rare moment of leisure, I was huddled on the sofa in the corner of the living room, fiddling with a handheld game console I'd just gotten from the Interastral Peace Corporation, having a great time.
As for Herta, she was standing in the center of the room, where at some point she had placed a small Simulated Universe access device that emitted a faint blue light.
She was standing with her back to me, arms crossed, staring intently at the constantly changing nebula pattern, seemingly thinking about some extremely complex problem, and her whole being radiated an aura of "don't come near me."
Just as I was immersed in the game world, my fingers flying, Herta's clear voice suddenly rang out, without any preamble:
"Little Gray-hair, hurry up and come test."
"!"
I dropped the game console in my hand as if by reflex.
Those two words, "come test," after the "training" of this period, had been firmly bound in my brain and body to a specific "research activity."
"Coming!" I replied, my movements as practiced as if I had rehearsed them countless times.
I quickly stood up, walked a few steps behind her, and very naturally stretched out my arms to embrace her slender waist from behind.
At the same time, my other hand also reached down without hesitation, skillfully lifting her skirt—she seemed to love this style, probably to facilitate "testing" at any time?—and accurately found the edge of her panties, hooked it lightly, and pulled it down to the bends of her knees.
Immediately following this, I supported myself, already having a reaction, aimed at that familiar, moist entrance, and exerted a slight force with my waist, successfully entering her tight body from behind.
The entire process was smooth and in one breath, so fast that there was almost not a single pause.
I had even prepared myself to welcome her low, bashful grunt and the ensuing trembling of her body.
However—
"??? What are you doing?!!"
The expected reaction didn't appear; in its place was a deafening, piercing scream filled with disbelief and anger!
Herta turned her head abruptly, those beautiful violet eyes wide open, burning with fury, as if she were about to swallow me alive.
"I said test—the Simulated Universe!!" She was almost yelling, so angry that her voice was a bit off-key. "What on earth are you thinking about all day long?! Pervert! Idiot!!"
The torrent of abuse left me dizzy.
Test... the Simulated Universe?
I only then reacted; she was indeed looking at that Simulated Universe device when she said "come test."
Got it wrong?!
I froze there, unable to advance or retreat, my face burning hot.
"Um... sorry, I..." I tried to explain.
But strangely, although Herta was scolding me fiercely, and her face was red with anger, she... she didn't immediately push me away, and didn't use that ubiquitous magic wand of hers to give me a heavy blow.
Her body remained in the posture of being entered by me from behind, just trembling slightly because of her anger.
"..."
"..."
A bizarre silence permeated the air.
The scolding had stopped, but we still maintained this extremely awkward and intimate posture.
"...Forget it! Since you've already entered... then... then hurry up and finish!!"
After she finished speaking, she snapped her head back, no longer looking at me, but the slightly flushed earlobes exposed her lack of calm.
Although the process was full of farces and scares, since the "highest directive" had already been issued... I naturally had no objections.
And so, right there next to the Simulated Universe device, with an extremely bizarre start, we once again began an "investigative" deep exchange.
I thrust into her from behind with long, powerful strokes, her tight pussy gripping me like a vice while her small breasts bounced with each impact. Herta tried to keep her focus on the Simulated Universe device at first, but soon her moans grew louder, her slender body shaking as I pounded deeper and faster. I reached around to rub her swollen clit while slamming into her, drawing out sharper cries. When her orgasm hit, she squirted hard around my cock, her walls spasming wildly. I kept thrusting through it, then buried myself deep and unleashed another massive load, flooding her womb with thick, heavy ropes of hot cum. Her belly swelled noticeably again from the sheer volume as I pumped load after load inside her. When I finally pulled out, a huge torrent of creamy white semen erupted from her smooth pussy in powerful gushes, splashing down her long thighs and forming messy puddles on the floor while her body continued to twitch from the intense creampie.
After a fierce battle, I finally released myself.
After we both recovered from the lingering aftertaste of desire, I carefully helped her wipe her body clean and tidied up our messy clothes.
Herta was red-faced the whole time, not saying a word, only occasionally giving me a glare that could kill.
Then, in an atmosphere of indescribable silence and awkwardness, I silently walked to the Simulated Universe access device and began the day's... "Simulated Universe test."
Herta sat to one side, hugging her arms, still glaring at me angrily, not knowing whether she was supervising my test progress or thinking about how to express her instructions more accurately next time.
