The Great Sage's Laboratory: Secret Magical Power Measurement

The cold floor of the library. On top of it, Tusma and Lurua shared only each other's breaths and heartbeats, as if every sound in the world had been cut off. Tusma's hot, rock-hard erection pressed firmly against her soft lower abdomen, mercilessly awakening sensations she had long forgotten. Lurua's 2,200-year-old reason crumbled into ashes and scattered at a single one of his devilish whispers.

'Research... Y-yes, I must continue the research...' She clung to those words like a lifeline. It was the only justification left that could preserve her final shred of dignity in this depraved, obscene situation.

"Th-this isn't the place... There are people watching..." Lurua whispered in a voice that sounded almost tearful. Her resistance was so feeble it came across more like an invitation.

"In that case... wouldn't your personal laboratory be perfect, Professor? No one would disturb us there, and we could immerse ourselves in a truly thorough 'research' session."

Tusma breathed even hotter air into her ear, then lightly licked her earlobe with the tip of his tongue.

"Hic...!" Lurua's entire body trembled as if seized by a convulsion. She had already lost any will to resist. No—she didn't want to resist. With a shaking hand, she drew a small magic circle in the air. Space twisted, and a golden portal opened silently.

"F-follow me..." she managed to squeeze out.

Tusma smiled with satisfaction, took her hand, and stepped through the portal without hesitation.

'Oho, so this is what passing through a portal feels like.'

The moment he crossed over, an entirely different scene unfolded before his eyes. This was Lurua's private laboratory. Towering bookshelves reaching all the way to the ceiling were packed with ancient grimoires. In the center of the room stood a massive obsidian table engraved with intricate magic circles. The soft glow from various rare artifacts and magical tools filled the space with an air of mystery.

Yet even within that scholarly atmosphere, feminine touches like a plush velvet sofa by the window and a delicate tea set revealed her hidden tastes. Most importantly, the room was protected by perfect soundproofing and shielding magic. Whatever happened inside would remain a secret sanctuary known only to the two of them.

"Ahem, welcome to my room. Ah...!" The instant the portal closed, Lurua's legs gave out and she nearly collapsed. Tusma caught her firmly around the waist, supporting her. Then, quite naturally, he began stroking her ass.

"Professor."

"Hah... L-let go! This is my laboratory. Without my permission, you can't just... arbitrarily..." Her words lacked any real strength.

Instead of releasing her, Tusma pulled her even tighter against his body. Once again, his overwhelming presence pressed hard against her lower abdomen.

"Hah...!"

"Professor, shall we begin our research? I'd like to show you very deeply and thoroughly just how special my constitution is."

"Sp-special constitution...?"

Still holding her in his arms, Tusma carried her toward the plush sofa by the window. Cradled helplessly in his embrace as he moved her, Lurua trembled with a mixture of shame and an intense arousal that came flooding in.

On the sofa, gently laid down, Lurua gave up all resistance. She had accepted that her ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠fate now rested in the hands of this dangerous commoner. Tusma looked down at her, slowly stripping away her clothes as if admiring a precious work of art.

Her ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠professor's robe, blouse, skirt... With each garment removed, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠more of the sanctuary that had been denied to anyone for 2,200 years was revealed. Finally, she lay defenseless before him wearing nothing but a pink lace lingerie set. Her voluptuous breasts threatened to spill out of her bra, and her panties were already soaked through, clearly outlining the shape of her most intimate place.

"You're beautiful, Professor. More so than any ancient relic..."

"Mmm..." At Tusma's praise, Lurua blushed and turned her head away.

Tusma reached for the hook of her bra and unfastened it without hesitation. Her bountiful breasts, freed from their confinement, bounced up with elastic firmness. The cherry-like nipples at their peaks were already stiff and erect, standing proudly as if tempting him.

"Shall we have a taste of you, Professor?"

"Haaah..."

Tusma took one breast into his mouth and sucked gently, like a baby nursing. At the same time, he rolled and pinched the other nipple between his fingers.

"Ah! Ahn! Hngh! No... not there...!"

The stimulation, the first she'd felt since last time, made Lurua's back arch like a bow. Her body had already become a perfect female. It reacted sensitively to every touch and kiss from Tusma, letting out screams of pleasure.

Tusma licked and sucked every inch of her body, awakening all her senses. The nape of her neck, her collarbone, her navel, the soft flesh of her inner thighs... Everywhere his tongue passed felt like it left trails of fire.

"Aahh..."

Finally, his face reached between her legs. Tusma gently pulled her last remaining panties to the side. A glistening pink flower, slick with her juices, was revealed.

"What a pretty pussy. Now, shall we directly analyze Professor's 'fountain of magical power'?"

"Th-that's so dirty...!"

Tusma whispered mischievously as he brought his tongue to her most sensitive clitoris.

"Kyaaaaaah!!"

A sharp scream far more intense than anything before burst from Lurua's lips. Tusma's skilled tongue work mercilessly severed the last thread of her reason. He licked, sucked, and lightly nibbled her clitoris, driving her relentlessly toward the peak of pleasure.

"Ah, no! I'm... I'm coming, I'm coming...!!"

Shiiiiiiiii!

Lurua's body went rigid as a powerful gush of hot fluid erupted from her urethra. It was a violent orgasm as if a dam had burst, releasing everything she had held back for 2,200 years all at once.

"Haa... Haaah... Haa..."

While she panted, lost in the afterglow of climax, Tusma stood up and removed his pants. Once again, that ferocious monster entered Lurua's field of vision.

"Professor. This is the source of my magical power. This time... I believe we must inject it directly into your lewd pussy to measure the magical reaction."

"B-but I was supposed to be the one conducting the research... Hah...!"

Lurua could offer no resistance. It felt as though she were obeying the command of an absolute ruler who would accept no refusal.

Wide open. As if in a trance, Lurua spread her legs. She already knew exactly where this research would lead. And her entire body craved it.

"I'm going in."

Tusma pressed his lower body between her legs and aligned his massive glans with her wet entrance. A tense, taut pressure. Once again, Lurua's hymen trembled faintly as it sensed the presence of his glans.

"Ah... Aah..."

Lurua looked up at him with eyes filled with a mixture of anticipation and fear. Tears shimmered in them—tears of shame, and tears of joy.

'Th-this ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠time... I'm finally going to become one with Tusma.'

Twice before, their union had been interrupted, preventing her from offering him her virginity. She didn't fully understand why she felt she had to give it to him, but she had regretted missing those chances.

Now, the end was in sight.

Slowly, Tusma gently wiped away her tears with his finger. Instead of tearing through her hymen, he began softly rubbing the thin membrane with the tip of his glans.

"Hngh...! Ahn...!"

His actions—teasing only her most sensitive entrance without entering—drove Lurua to the brink of madness.

"Put it in... Please... Tusma..."

A plea flowed from the lips of the Great Sage and hero. She no longer cared about her dignity. All she wanted was for the man before her to completely claim her.

"If it's your request, Professor..."

Just as Tusma tensed his hips, ready to pierce her final sanctuary—

At the same time, a holographic image of a man appeared above the obsidian table in the center of the room. It was a dignified white-haired elder—the current headmaster of the Magic Academy.

"“—?!?!”"

The two of them froze completely. There could not have been a worse possible timing.

"H-headmaster...!" Lurua let out a silent scream, her face turning deathly pale. She frantically sat up and began covering herself with the clothes she'd thrown aside. Tusma quickly pulled up his pants and looked for somewhere to hide.

What is it, Professor? And where are you right now?

The headmaster's sharp eyes scanned the laboratory through the hologram. Fortunately, they were in a perfect blind spot and weren't discovered.

"I-it's nothing, Headmaster. I was just about to begin a new research project." Lurua barely managed to reply, her voice trembling. Her face was a mess of shame, frustration, and regret.

Hmm? I see. Please hurry. We've detected signs of a rather large dimensional rift. This is something only you can handle.

The moment the headmaster's image vanished, Lurua collapsed on the spot.

"Haa... Haa..."

She looked at Tusma, who was standing awkwardly behind the bookshelf, with eyes full of longing. At the same time, a hot flame still burned within that gaze—one that promised there would be a next time.

"T-today... we'll have to stop here, Student Ssex. We'll continue our 'research' another time."

"Understood... It can't be helped if there's urgent business."

"R-right..."

She bit her lip in frustration. Then, as if suddenly remembering something she'd meant to ask, she looked at Tusma.

"Ah, but there's one thing I'd like to ask."

"Yes, what is it?"

Lurua averted her gaze slightly and asked shyly.

"That day... in the forest... when I... um... when I jumped on you."

Professor Lurua seemed to remember that day's events as her having gotten so excited that she tried to force herself on a student. In reality, it had all been because of the Paint of Corruption.

"That day, I lost my panties... Did you... perhaps see them...?"

"I'm keeping them as a treasure."

"Hngh...!"

At Tusma's bold answer, Lurua's face turned bright red.

"I-is that so? A treasure... I'm glad you like them."

"I also really like the dagger you specially prepared for me."

"I'm glad about that too... And if you have those kinds of preferences..."

Professor Lurua's face grew even redder as she slowly slipped her hand under her skirt. With a soft rustle, she removed her panties right in front of Tusma and handed them to him. The warm heat of the blue-striped panties transferred through his hand. The slightly damp spot in the center, shaped like her pussy, was especially perfect.

"If something like this makes you happy... please accept it."

"I love you, Professor Lurua. It's the best gift ever."

"Hah~!!"

The moment Tusma accepted the panties and immediately confessed, Professor Lurua's face flushed an even deeper shade of red.

"Ahem! W-well then, we'll continue the research next time. I-I-I have urgent matters to attend to, so I'll be going!"

Professor Lurua pulled out a new pair of red-striped panties from her magic inventory, put them on, opened a portal, and left.

"...She must really like striped panties."

Left alone in the laboratory, Tusma looked down at his still-throbbing desire and let out a wry laugh.

"I missed the chance by a hair again, but at least I got a pair of panties as a gift."

Tusma wasn't impatient. The big shot known as Lurua Seinsti was already firmly in the palm of his hand. Today's reaction had made it crystal clear that her heart was already filled with him. Taking her virginity was now only a matter of time.

'Alright. I'll put the lewd rendezvous with the Professor on hold for now...'

As Tusma left the laboratory, he began thinking about his next plan. His gaze had already moved beyond the Bloody Rose to another first-year faction—the Golden Iris, led by another delinquent girl.

'Elara Bonhelm... you arrogant golden-haired lioness. I'll be sure to stain those expensive panties of yours with my cum. Heh heh...'

His wicked smile, aimed at his new prey, echoed through the dark hallway. There was still plenty of time left before the end of the first semester of the first year.
