The Abyss Called "Vacuum" and the Climax of the Doppelganger

It was a dizzying pink abyss.

When you actually get close to that forbidden area wide open by the black-stockinged legs, the first thing that assaults your senses is not sight, but an extremely intense heat wave. It's not just body temperature, but more like the bio-heat energy emitted by this "skin" working overtime to cater to males.

A strange scent filled the air—the musky aroma unique to mature women, mixed with the sweet, metallic taste of your saliva left on your stockings, and that lingering, faint latex smell that seemed to come from another dimension. These three scents intertwined at the tip of your nose, weaving an inescapable web of desire.

"Do you see it clearly? This is the place you've been thinking about for three years..."

Ms. Sayama—or rather, A-Jie—pressed the back of your head with one hand, forcing your gaze to look deeper. Her voice trembled slightly, sounding both provocative and desperately pleading.

You hold your breath; the structure there is shockingly detailed. There are no blurry mosaics; every fold, every swollen pink spot, is clearly visible. Even the transparent liquid overflowing from the slightly pulsating entrance seems so real that you wonder if this is truly some kind of magical artifact.

"Coo-choo..."

You could no longer bear it, and like a thirsty beast, you buried your face in it.

"Aaaaaah—!!!"

A sharp, high-pitched female scream instantly shattered the silence of the office.

The moment your tongue touches that soft flesh, it feels like an electric shock. It's not cold silicone, but scalding hot, almost pulsating, living flesh. The soft inner walls contract and writhe wildly under your licking, as if countless tiny mouths are sucking on your tongue.

The sensation was bizarre. It was like licking a "shell," but the tactile feedback was more vivid than anything you'd see in an action movie. The secreted fluid was slippery and warm, with a faint salty taste and… a citrus scent?

"No...don't lick there...ah...this body...is too sensitive..."

Above your head, A-Jie's voice had completely changed. It was no longer a man's heavy breathing, but purely Sayama Misato's soft moans. His hands gripped your hair tightly, his nails almost digging into your scalp, his legs convulsing uncontrollably, and the inside of his black-stockinged thighs rubbing wildly against your ears, making a "buzzing" sound.

"Damn it... since you like it so much... then... then come all the way in!"

Suddenly, a tremendous **** rips your head off.

Before you could react, Ah Jie suddenly grabbed your collar and pulled you to your feet.

His face was flushed, and his eyes were glazed over, almost dripping with tears. His once neat white shirt was now soaked with sweat, clinging tightly to his body and outlining the shape of his large breasts.

"I...can't hold back anymore..."

As he spoke, he impatiently unbuckled your belt. The movements were rough and wild, yet carried a urgency unique to women.

When that moment finally arrives, you feel as if you are enveloped in a ball of molten lava.

"Pfft—"

Accompanied by a blush-inducing splash, you enter that mysterious passage.

"Ugh...!"

You and A-Jie both let out a muffled groan at the same time.

It's too tight! Too tight!

It wasn't just a matter of physical tightness; it was more like a vacuum suction. The interior of this "skin" seemed to have been created to perfectly fit you, every inch of its inner walls clinging tightly to your hardness, leaving no gaps. You could feel that layer of "skin" deforming and expanding with your invasion, and that feeling of being swallowed made your scalp tingle.

"Ah...it's so big...this feeling...is this what it feels like to be penetrated?"

Ah Jie tilted his head back, his long neck forming a graceful arc. He braced his hands on the desk, his waist sinking deeply, his full buttocks, encased in black stockings, rising high as if welcoming your thrust.

"Move...move faster! Be a man!"

He's urging you on, his voice a mixture of indescribable excitement and pain.

Your reason completely snapped. Good brothers, homeroom teacher, sex toys—all were thrown to the back of your mind. Before you lay only this incredibly alluring body, this "woman" relentlessly demanding from you.

"Slap! Slap! Slap!"

The sounds of flesh colliding echoed in the small space, crisp and lewd.

With each impact, her heavy, enormous breasts would sway violently with inertia, creating dazzling waves in the air. Finally, the white shirt buttons gave way and flew off with a "pop," instantly releasing the two mounds of soft, white flesh, which bounced up and down with your movements.

"Ah...ah...it's too deep...it's going to reach that spot..."

Ah Jie's voice grew increasingly seductive and softer. He seemed completely immersed in the pleasure he was experiencing with Sayama Misato; his once-manly eyes were now a blank, frenzied void.

You gripped his waist tightly with both hands—the skin there was so smooth it was almost impossible to hold. As sweat seeped out, the surface of that "skin" became even shinier, and the feel was astonishing. You looked down at the place where the two of you were joined, your thing was frantically going in and out of that stretched pink opening, bringing out a lot of clear fluid that stained the edges of the surrounding black stockings.

“Look at me…”

Suddenly, A-Jie turned his head.

His black hair was plastered messily to his face, and there was a glistening saliva at the corner of his mouth. His expression was unlike anything you had ever seen before—it possessed both the maternal glow of Professor Sayama and an **** lewdness born of depravity.

Tell me... who is standing in front of you right now?

He asked breathlessly, a dangerous glint in his eyes.

"Yes... Mr. Sayama..." you answered uncontrollably, but the movements below your waist became even more intense.

"wrong……"

He suddenly tightened that area, and the powerful suction almost made you surrender.

"It's your good brother...using your body...draining you dry! Haha...Ahhh!!"

This simultaneous explosion of mental **** and physical ecstasy made you let out a low, beast-like growl.

"I can't take it anymore... I'm going to... I'm going to break down..."

Ah Jie's voice suddenly turned shrill, and his body trembled violently. Those long, black-stockinged legs suddenly lifted up and wrapped tightly around your waist, the heels of their high heels digging deep into your back muscles.

"Give it to me...give it all to me...shoot it inside! Fill this skin...fill the teacher's womb!"

At this final command, you feel your mind go blank, and all your senses are focused on that one point.

A surge of scalding heat, like a volcanic eruption, poured wildly into the unfathomable depths of that body.
