The Black Box's Gaze
The dull thud echoed through the space for a simple reason. One look at the black-haired girl’s face—brows furrowed in irritation, one hand pressed to her forehead, cheeks puffed out like a sulking child—was enough to piece it together. She had marched straight into the wall that looked like frosted glass and smacked her forehead right against it.
In this vast, pitch-black void filled with darkness like a miniature universe, floating “windows” drifted everywhere, each reflecting scenes from different parts of the underground facility beneath the art museum. Thanks to these shortcuts, the two girls could appear anywhere they pleased. Normally, nothing should have been able to block their entry, yet this particular space refused them.
“What are we going to do, sis?”
“...Tch. I’ll break it.”
“That doesn’t seem like a very good idea. If you smash it now, the Counselor inside will collapse along with the space.”
The black-haired girl nodded at her sister’s warning while peeking into the “pitch-black box” she had created using one of her own scales. The interior, which should have been transparent, was clearly malfunctioning.
“...Yeah. You’re right.”
Because the box had been woven with so many intricate settings, recklessly destroying the walls would cause an irreversible collapse that would drag everything inside down with it. Following the clown-masked girl’s orders, the space had been configured to limit the singularity’s influence, allow easy observation from outside, and permit physical passage. But she had also made sure the constantly shifting singularity of the containment subject would affect the space itself—purely for entertainment. That was why the interior changed appearance with every counseling session, and why the arrogant man had been able to seize control so easily.
“...Ugh, seriously, how cocky. Does he really think I can’t get in just because he blocked it?”
The newly overlaid concept rejected any outside intrusion. It was the idea of “a space for only the two of them, where no one could interfere.” Still, the fact that the scene beyond the window remained faintly visible suggested the control hadn’t completely transferred.
“Hmm... It’s definitely rejecting anything trying to enter from the outside...”
The black-haired girl muttered while resting her small hand against the translucent wall. The white-haired girl, cradled in her sister’s other arm, watched the situation with calm detachment.
“If we make a few holes from the inside outward, the ‘only the two of them’ concept should weaken... and then...?”
...?
“Haaang...! Ah, haaang!”
Plap! Squelch, squirt! Slap, squelch, plap!
“Ugh...”
The moment the black-haired girl created the holes, lewd moans and wet, obscene sounds flooded through from the other side. As expected, the barrier had been pierced; the view beyond was now crystal clear.
“...Mm. They were in the middle of mating.”
“Whoa...”
The air inside the box was thick and sweltering, heavy with the unmistakable heat of intense sex. The Counselor lay on the bed while the beautiful woman with lavender hair straddled him, slamming her hips down again and again.
Plap! Squelch, squirt! Slap, squelch! Plap, squirt!!
Their joined bodies were already overflowing with a milky mixture of semen and love juices, each thrust producing vulgar, wet noises.
“Lav...! I-I’m... hah, again...! Ngh...!!”
“Haaang...! Haaang...! Inside, it’s fine... hah, it’s okay...!”
Spurt! Spurt, spurt! Splurt! Twitch, twitch! Twitch! Twitch! Twitch!!
Squish, squelch! Squirt, squelch!
The man beneath her groaned as if he were drowning, his lower body trembling while he poured everything deep inside her. Yet the woman never stopped moving, even as he came.
“Hah... hah, I’m coming... I’m coming, but... it won’t stop coming out...”
She accepted the fresh, hot seed flooding her depths with visible delight, her body quivering as ecstasy overtook her. Her hands cupped her own face while she gazed down at him with loving, almost dangerous eyes. Those lavender irises, despite their soft and mystical color, carried a distinctly predatory glint.
Squelch, squish, squelch, twitch... squelch! Spurt, gush!!
Thick fluids were already being forced out around their connection, but she refused to stop.
“You’re still okay, right...? Hah, it’s only been five times. We can do more. Hngh, hah... Let’s feel good together.”
“Ah... ah, no...”
“We agreed... hah, not to say ‘no,’ remember?”
“Ngh... hah, hngh...”
The man had clearly already climaxed multiple times under her relentless hips. He sounded like he was at his limit, yet she simply looked at him sweetly until he gave the answer she wanted.
“Hah...!”
Spurt, spurt...!! Spurt, gush! Splurt!
Even just muttering his agreement caused his manhood to harden even further than before, unleashing a far more powerful release that painted her insides with his color.
A thin trickle of blood ran from his nose, but the woman only smiled and continued rolling her hips in pleasure. The false manifestation she used for eating was not the simple copy the profile suggested; it followed the law of conservation perfectly. Even if his revitalized shaft could produce fresh semen, the burden still fell on his own vitality.
If this one-sided milking continued, he really might dry up and die, the white-haired girl thought while gently covering her sister’s eyes. But that wouldn’t happen. Once the woman had consumed his affection and attention through this act, she would simply share her own vitality with the Counselor—as long as his feelings for the one called Lav never cooled.
“...Perpetual motion... I suppose?”
Having reached that conclusion, the two pairs of eyes remained fixed on the intense coupling beyond the wall.
Plap! Plap! Slap! Slap! Slap! Slap!!
“What are we going to do, sis?”
“Wow... whoa...”
Unlike herself, who placed little meaning on reproductive acts, the black-haired girl’s eyes sparkled with genuine fascination. The white-haired girl felt a flicker of unease—not because her sister was embarrassed, but because that bright, curious gaze seemed to hold an odd, almost unsettling interest in the act itself.
“Hngh, hah...! It feels so good... hah, I want to... stay like this forever... haaang...!”
Every time she lifted and slammed her hips down, swallowing his slick, cum-covered length with her tight entrance, her large breasts bounced heavily, captivating his gaze. Her plump thighs and round hips clung to him with wet, sticky sounds no matter how many times she dropped down. Her waist was slim and toned, the muscles clearly defined, while the rest of her body was the perfect embodiment of male fantasy—full where it should be full, tight where it should be tight. It was an unrealistically flawless figure, almost lacking individuality because of how perfect it was. Yet the sweat-dampened lavender hair and those same-colored eyes, shining with near-obsessive affection, made the endless connection and pleasure feel undeniably real.
“But why does this future lead to that guy’s death?”
The white-haired girl watched the two of them with emotionless eyes. The man panted like an animal, still rubbing his oversensitive shaft against her even after repeated climaxes. The act looked excessive, but neither of them was in immediate mortal danger. A woman willing to do anything for his love, and a man who gave her all the attention and affection she craved in return. On the surface, it seemed perfectly balanced. So why...?
“Ah, haaang! This time too... hngh, it’s twitching so hard inside...”
“Hah, hngh... Lav...”
“Yes... your woman is right here. Hah, hngh... I’m not going anywhere... hah, mmph...”
He pulled her down into his arms, their fingers still intertwined. Satisfied by the heavy weight of her breasts against his chest and the warmth of her body, he captured her lips and drank deeply from her mouth, tongues intertwining as they shared saliva.
Chu, suck, slurp... suck, kiss...
“Hah, hngh... chu... hah, hah...!”
Even while kissing, their hips never stopped moving, both of them climaxing again and again, further staining the sheets.
“Whoa... mating is supposed to be for the continuation of the species, right...”
“Ah...?”
At her sister’s sudden murmur, the white-haired girl suddenly realized something she should have considered from the beginning. The purpose of their act had looked like nothing but raw, filthy pleasure, so she hadn’t thought of it until now.
“Hah... hngh... Do you love me? Hah, tell me.”
“Hah, ngh! I... love you.”
“More than anyone else... hah, do you love me the most?”
They continued their breathless, sticky conversation between kisses, lips brushing even as they panted. He trembled as he came inside her again, but—
“Ngh, hah, I love you, but... I... Harpy is...”
“...”
Even while drowning in pleasure, he still couldn’t let go of that one thing. At his hesitation, her eyes turned cold. She stared down at his melted expression for a long moment before finally stopping her hips.
“L... Lav...?”
“...A child, huh. I see. They say men want to impregnate the woman they truly love... hah, and the finest female.”
She still had his freshly spent length greedily swallowed inside her. With deliberate pressure, she bore down.
Squelch...!
“Hah...?”
Her body, capable of changing at will, responded to his unspoken desire. Since simple stimulation was no longer enough, her inner walls transformed into the ideal shape of a supreme pleasure sleeve. Countless firm ridges pressed against him, writhing with unnatural movements as they began to milk him, demanding he give her his seed.
Squeeze, squelch, squeeze...!
“Hngh...!”
“Answer me. You want to impregnate me, don’t you?”
“Ngh... hah...!”
Her movements had stopped, but now her inner flesh had become far more intricate, writhing and squeezing with terrifying precision. He let out a dazed moan, mind going blank. The walls rotated and rubbed against every sensitive spot even without her hips moving, ridges standing up to torment him.
Squelch, squeeze...! Squeeze...!
He instinctively knew that the moment she started moving again, he would be unable to resist and would be forced to pour out everything like a broken faucet.
“...Hurry up and answer. You’re going to fill my womb with your hot seed and impregnate me.”
Squelch...!
As she slowly lifted her hips, her walls clung tightly to him, pulling upward as if trying to drag his very soul out.
“Ngh... hah, I...!”
His glans caught at the entrance, the only ridge on his shaft. She refused to let go. If he tried to pull out, her entrance would drag everything along with it. Her hips refused to rise any higher.
“Hah... hah...”
If she dropped down now... then... then... He trembled, sensing that this single thrust would feel incomparably better than anything before. Once he was swallowed by her perfectly shaped inner walls, there would be no room left in his mind for anyone else.
“...Then let’s start again, okay? This time, it’s sex for making a baby.”
“Aah...”
He had no idea what would happen if he answered. Her body resembled a human’s, but it wasn’t truly human. ...No. Normally, no matter how many times he came inside her, there would be no egg to fertilize. However... if her question and his answer satisfied the conditions of her false manifestation, it could become possible. But false manifestation followed the law of conservation perfectly. For a new life to be born... an equivalent life would have to be paid as the price.
“Sis! Stop the Counselor from answering...!”
