The Steel Knight's Hidden Weakness (4)

Isabel's back arched like a drawn bow against the cold metal shelf as her lewd moans echoed through the room. “Haaah… Ahn… Aaaah~!”

The first orgasm she'd experienced from nothing but fingers was like molten lava, melting away the iron will that had defined her. Every muscle in her body convulsed. Stars exploded before her eyes. For a moment she forgot who she was, where she was—lost ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠entirely in the primal pleasure Tusma had granted her. She panted, utterly consumed by it.

Shhhiiick!

Hot fluid gushed from her urethra, forming a small puddle on the floor of the old armory. The obscene evidence of her body's surrender proved beyond doubt that the once-noble knight Isabel was no more.

“Haa… Haa… What… what was that… just now… that feeling…?”

Isabel barely managed to refocus her gaze and look up at Tusma. A conqueror's smile played across his face. The realization of what this man had done to her flooded her with shame, coloring her cheeks crimson. Yet her body was honest. Even before the aftershocks of climax had faded, her pussy twitched again, already craving the next wave of pleasure. Her juices flowed endlessly, trickling down the insides of her thighs.

How is this possible… Just his fingers… and I came? From a commoner’s fingers…?

Her mind was a storm of confusion. But far stronger than that confusion was the insistent signal of desire radiating from her own flesh.

“This is only the beginning, my knight.”

Tusma withdrew his fingers from her drenched slit and instead pressed the scorching, massive head of his cock against her entrance. The monstrous presence, boasting an extraordinary size, should have inspired terror. Instead, it awakened an unbearable anticipation.

“Ah…”

Isabel’s body trembled faintly between expectation and fear.

“Now, are you ready to accept your lord?”

He seized her firm thighs with both hands and spread them wide. Her secret, lewd pussy was laid completely bare before his eyes.

“Aah…”

Beyond the glistening, narrow entrance slick with her nectar, her taut virgin membrane was visible. Tusma did not hesitate.

Thrust!!

“Nngiiiiiih~?!?!”

A scream blending agony and ecstasy tore from Isabel’s throat. The thin barrier that had symbolized her final purity was mercilessly ripped apart by his ruthless invasion. Blood mixed with her juices and ran down her thighs.

She couldn’t process the enormous, alien sensation that had pierced her in a single stroke. It hurt. It hurt as if she were being torn apart. Yet as if mocking that pain, an even greater wave of pleasure crashed over her entire body.

“Ah! Aaaah! It hurts…! It hurts, but…! It feels… it feels so good…! What is this…! My body… it’s no longer mine…!”

With his enormous cock buried inside her, Tusma drove all the way to her cervix in one brutal thrust, battering it with blunt force. The impact sent Isabel into another violent orgasm, her body shaking uncontrollably.

Shhhiiiiiiick!!

“Haaauuuung… I’m coming again… I came again… Ahn…!”

“Do you understand now, Isabel? What you truly craved wasn’t some forbidden poison. It was this very sensation. Your body does not lie.”

Tusma began moving his hips in earnest. The cold armory was instantly filled with the heat of their bodies and the wet, obscene sounds of flesh slapping against flesh.

Smack! Smack! Squelch! Smack!

“Haaang! Ah! Ahn! Ahk! Stop…! Please stop…! My body… it feels like it’s melting! My womb… my womb is being stabbed… it’s going to break…!”

Isabel begged, yet her hips instinctively rocked back to meet his thrusts. The powerful physique she had trained her entire life had been reduced to nothing more than a tool for receiving pleasure.

Tusma grabbed her E-cup breasts, licked the sweat from her back, and fucked her like a beast. Her once-unbreakable pride melted away along with his saliva.

“Lady Elara… what about her… I must… protect her… Hngh!”

Even within the fog of pleasure, the last remnants of her loyalty spilled from her lips. Hearing it, Tusma gave a wicked smile.

“Forget that bitch’s name. From now on, you will swing your sword only for me. You will spread this cunt only for me. You will offer these tits only for me. Understood?”

He slapped her ass hard enough to make it ring.

Slap!

“Kyaaang!”

Isabel trembled from the mixture of pain and pleasure, tears beginning to fall. Those tears were both of humiliation and of liberation. The blind loyalty that had bound her for a lifetime finally shattered, and in that moment she accepted her new master.

“…Yes…. Yes, Master…”

The words of submission finally flowed from her lips. Hearing them, Tusma smiled with satisfaction and poured every drop of his hot seed deep into her womb.

“Ugh…! This is the contract between you and me!”

Spurt!! Spluuuurt!!

“Heeeuuuung~!! Aaaah! Master’s cum…! It’s filling… my womb… so full…!”

Isabel convulsed from head to toe, losing consciousness in the ecstasy of receiving her owner’s seed. When he finally pulled his massive length out with a wet squelch, a mixture of blood and thick semen poured down her thighs.

The Steel Knight had finally melted down inside Tusma’s furnace and been reborn in a new form—as his loyal, lewd bitch.

A short while later, Tusma helped the panting woman to her feet and gave a low command.

“Now, Isabel. I shall give you your first mission.”

“Yes… Master…?”

“Clean my cock.”

At his polite yet utterly unrefutable order, Isabel’s eyes widened in shock. But after only a brief hesitation, she obediently dropped to her knees at his feet. She could hardly believe she was crawling on all fours, yet her body moved with natural grace, as though it had already been branded by its new owner.

Heh heh, how the mighty have fallen. The Steel Knight turns out to be nothing but a bitch who licks my cock in the end.

Tusma chuckled inwardly as he looked down at the crown of her head. Isabel extended her trembling tongue and licked the drop of semen clinging to the tip of his glans. A lewd yet sweet, addictive flavor ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠spread through her mouth. She closed her eyes and began to lick his entire shaft with the reverence of a believer worshiping a holy relic. She cleaned every inch—the hard pillar, the heavy balls, even the mixture of her own juices that coated them—swallowing it all without leaving a trace.

“Excellent. But we’re not finished yet.”

Tusma, satisfied with how clean his cock had become, jerked his chin toward the black boyshorts that had fallen to the floor.

“Finish with that filthy scrap of cloth.”

Isabel silently picked up her torn and soiled panties. They were the last undergarment she had worn as the knight Isabel Martinez. She gently wrapped the fabric around his cock and wiped it clean. The act felt like a ritual of complete farewell to her former self.

Some time later, when Isabel regained her senses, she found herself cradled in Tusma’s arms. Her body felt languid, and her mind was strangely at peace. It was a sense of security she had never known in her entire life.

“……Master.”

“Yes, my Isabel.”

Tusma gently brushed her sweat-dampened hair aside.

“At first… I thought you were just tricking me with strange drugs so you could play with my body.”

Even though she ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠suspected that, she still drank the potion. The effects of the Paint of Corruption really are incredible.

“But… the medicine’s effects were real. I can feel the ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠side effects of my drug addiction fading away. My body feels more energetic… and the fatigue and mana depletion…??”

As she listed the effects one by one, she realized this was no ordinary medicine. It had to be absurdly expensive.

“How did you get something like this…? It seems like the kind of medicine even most nobles couldn’t obtain, let alone a commoner…”

“It’s something only I can make. Keep it a secret.”

Isabel stared at him blankly for a moment, then nodded.

“You’re amazing… I promise.”

She nestled back into his embrace, savoring his body heat. Then she lifted her head slightly and asked another question.

“What should I do from now on?”

“Act exactly as you did before. Pretend to be Elara’s loyal knight. But your true master is me. From now on, you will be my eyes, my ears, and my sword—moving from within the Golden Iris.”

“As you command.”

Isabel answered without hesitation. Tusma’s orders had become the very reason for her existence. Her loyalty to Elara had vanished like dust before the overwhelming pleasure and salvation he had given her.

“And this.”

Tusma handed her another small white vial.

“This is my ‘grace.’ Every time you offer me your loyalty, I shall bestow it upon you. With this, you will no longer need to rely on that cursed poison.”

“Ah…!”

Isabel accepted the vial with eyes full of gratitude. It was more than a simple remedy. She could feel with her own body that it not only cured her existing addiction but was also healing the damage that had been destroying her. At the same time, it was a sweet reward from her master—and a addictive shackle that would bind her to him forever.

“Thank you… Master…! I will never forget this grace for the rest of my life!”

She knelt at his feet and reverently kissed the back of his hand. It was the moment she was perfectly completed as Tusma’s personal fuck-pet.

Having successfully conquered Isabel, Tusma turned his attention to his next target: Selina Loren. He had already gathered considerable information about her weakness through Aria. Illegal gambling debts. That was the key that would strip away her cunning mask.

I never expected to make use of such an unexpected connection here. Heh heh…

Tusma recalled the recent events. The sweet and lewd time he had spent at the Maple Honey Shop. The lewd employee he had fucked senseless back then—‘Mina Popo’—was none other than the daughter of that very massive Popo merchant guild.

Shall I go taste Mina’s pussy again after so long?

To solve the problem of Selina’s debt, Tusma set off to once again plunge himself into Mina’s welcoming folds.
