After that hard slap landed on the Teacher Devil's rear, a muffled, drawn-out cry immediately came from inside the room. Renji couldn't make out the words clearly—it was distorted, blurred, like a scream filtered through layers of obstruction.
Simultaneously, in the corridor, the Teacher Devil's hands—protruding from the two holes in the wall—began to flail erratically in the air, fingers clenching and unclenching as if trying to grasp onto something.
Her legs, sheathed in black lace stockings, also began to thrash wildly, her high heels stamping against the carpet in a chaotic, dull rhythm.
Renji stood behind her, watching her reaction, and a satisfied smile touched his lips. Then he glanced up at the wall space above her buttocks.
"What a shame the setting isn't right. If there were a large portrait of the Teacher Devil up there, it'd be perfect."
His hands moved to her waist, finding the hem of her tight skirt. Inside the room, the Teacher Devil let out another distorted, muffled sound. She seemed to sense something—that something was about to happen.
In the hallway, her lower body reacted dramatically. Her exposed hands trembled weakly, fingers splaying and curling.
Her legs, too, seemed to lose their steadiness, pressing inward and spreading outward unsteadily, swaying against the carpet.
Renji gripped both sides of her skirt and tore.
—Rrrip!—
The thin black fabric gave way violently, falling in tattered strips to the floor on either side. The Teacher Devil's pale, full buttocks were now completely exposed before him.
Her underwear was pure black, edged with lace. But the center narrowed drastically downward, until the part meant to cover her was as thin as a slender black string.
Only a small front section of the string was visible; the rest was swallowed entirely by the cleft between her buttocks, buried deep within.
"Wow, Teacher. I never expected you to wear such a proper, mature teacher's outfit on the outside, but something completely different underneath—a thong. But thongs are mature too, I suppose. Really, every aspect of your taste fits the image of a mature teacher. Alright, alright, Teacher, please stop moving your legs."
Renji took a step forward, closing the distance. He braced his legs against hers, intertwining them to still her frantic struggling.
Then, he gripped the plump curves of her buttocks and slowly spread them apart.
"Hmm… next is 'parting the clouds to see the moon.' Excellent. Full marks."
The Teacher Devil's small, delicate entrance was revealed. Under Renji's manipulation and her own physiological response, the tight ring would periodically flutter open, offering a glimpse of the pink passage within, before clenching shut again.
The thin black string of her thong lay across the top like a dividing line. Each time the entrance opened, revealing the soft pink interior, the string seemed to emphasize the separation.
Inside the room, the Teacher Devil let out another long, muffled cry. Renji still couldn't discern the words, but he could feel the emotion saturating her voice—fuller, more intense than when he'd merely slapped her.
Because…
—Squelch—
—Squelch—
...
That was proof enough.
The Teacher Devil's release was surging, and Renji had a perfect view from his position.
It mirrored the clenching of her entrance—no, it was even more exaggerated.
First, her lower lips contracted sharply inward, as if gathering tension. After reaching its peak, there was a wet, audible squelch, and they bloomed open, revealing a soft, deep opening.
A flood of warmth gushed and sprayed from that opening, splashing directly against Renji's groin.
And in his groin, Little Renji—dormant until now—received the implicit invitation. He had already evolved into his second form within the confines of Renji's pants, fully hardened and ready.
Renji released her buttocks, letting them settle back into place. He reached for his belt, unbuckled it, and pushed his pants and underwear down in one motion.
The proud general stood at attention, poised at the entrance, ready to lead the charge.
Renji straightened his posture, applied a gentle pressure, and the bestial head slipped inside with ease.
This time, from inside the room, he could hear the Teacher Devil's voice a little more clearly—a strained mixture of exhilaration and anguish.
—Squelch!—
—Squelch!—
...
Through the two small holes in the wall, the Teacher Devil's hands splayed outward, every finger rigid and straining. Her reaction was violent; even with her legs braced by Renji, she nearly broke free.
He could feel the muscles in her thighs trembling, twitching uncontrollably.
Renji drew a short breath, then drove his hips forward sharply!
The nearly thirty-centimeter length plunged into the Teacher Devil's soft, pink entrance in an instant—surged through her passage, forced open the entrance to her womb, thrust deep inside, and pressed relentlessly against the inner wall.
The outline of the bestial head became visible against the skin of the Teacher Devil's lower abdomen.
A trickle of blood seeped out, but it was quickly washed away by the flood of warmth that gushed from her.
Then Renji felt his length touch something solid. He glanced down, calculating the distance.
The Teacher Devil's waist was pinned between the walls, and the area of her womb was positioned close against the barrier. His thrust had likely penetrated her womb entirely, striking the wall behind it.
With that impact, the Teacher Devil beneath him went still for a moment—less than a second—before thrashing again as Renji began to move.
He gave her no respite. He launched into a continuous, driving rhythm, pouring all his strength into every motion.
With each thrust, his upper thighs slammed violently against her rear, compressing the soft flesh until it formed two, then three distinct folds.
Inside the room, the Teacher Devil's cries came in long, drawn-out waves—moans tangled with sobs. Her voice was constant, blurred by sensation.
Her womb was reshaped by his intrusion, the peach-like cavity distending upward into a cylindrical form that enveloped him completely.
"Good… Very good… Hah…"
Between man and devil, beneath the relentless motion of that fleshy connection, the wet, rhythmic sounds echoed steadily from the Teacher Devil's core.
Torrents of warmth spilled out.
Still unsatisfied, Renji leaned in further, closing the distance between them until his chest was almost against the wall. He braced his hands against the surface in front of him.
He focused every ounce of his physical and mental energy into his hips, into the motion, into the driving force of his thrusts.
He pulled back—
The fleshy bridge reappeared.
Then he slammed forward—
The bridge vanished.
—Squelch!—
...
This time, the Teacher Devil's rear was compressed into four, then five distinct folds. Her legs thrashed wildly again, splaying outward in a crab-like posture. Renji's own stance widened in response, but it did nothing to slow his rhythm.
He'd found the tempo with that last thrust. Now he followed it, driving forward again and again.
The fleshy bridge vanished, reappeared, vanished, reappeared…
With every impact, her rear was crushed into deep folds, nearly flattened against the wall.
Renji leaned his weight onto his braced hands, grunted, and released—the bestial head unleashing a flood of seed into the Teacher Devil's womb.
But because her womb was already pressed tightly against the wall, and after being relentlessly stretched and reshaped by his thrusts, it had been pushed flush against the center of the barrier.
There was no space left.
A large portion of his release had nowhere to go. It could only surge back. With a wet, choked sound, about half of his length was forced out by the backflow of seed.
"Hah…"
Renji pulled free completely. A gush of thick, white fluid followed, falling in heavy globs to the floor.
