My brain... is filled with the sensation of being pierced by a cock...♡
My brain... is filled with the sensation of being pierced by a cock...♡
Dreamlike blue light from the magic lantern flickered over the enormous bed in the center of the room.
With trembling fingertips, Celine slowly undid the buttons of her mage's robe one by one.
"Haah... ngh."
The heavy fabric dropped to the floor with a thud, exposing a body she had never revealed to anyone before. A slender waist and pale skin.
Her breasts were just a little too large to fit in one hand, while her naturally deep reddish-brown nipples stood stiff with tension.
The Tower Master stood with his hands clasped behind his back, observing her naked body from head to toe with greedy eyes, as if licking her with his gaze.
"What an excellent body. But there are far too many obstructions for me to directly connect the mana circuits."
"Obstructions...? What do you mean?"
The instant Celine asked with a frown in her golden eyes, a prickling spark shot from the tip of the Tower Master's finger.
Pajik!
"Ah, ngh...!"
In an instant, the red pubic hair covering Celine's groin burned away without a trace amid the sparks.
It was a high-level precision spell that left her skin completely unharmed while perfectly burning away only the hair follicles.
"W-What are you doing?! What are you doing to my body right now...!"
"A permanent hair-removal spell. Not a single hair will ever grow between your legs again."
Celine hurriedly covered her groin with both hands. But because her pubic hair had vanished completely, her fleshy, delicate crimson pussy could be seen clearly between her fingers.
Her face, pale from the extreme shame, instantly flushed bright red.
"What does such a vulgar act have to do with the Mana Synchronization Ritual, exactly?!"
"My tongue and bodily fluids need to make flawless contact with your mucous membranes. Get on the bed and spread your legs."
The Tower Master's voice carried an irresistible pressure.
Celine bit her lip until it bled. She resolved that if it meant obtaining the ancient grimoire, she would throw away this paltry pride of hers.
She lay back on the bed, raised her knees herself, and spread both legs wide to either side.
"Well, shall I personally appraise the taste of a proud virgin mage's innermost flesh?"
The Tower Master knelt at the edge of the bed and buried his face between Celine's fully spread pussy.
A grotesquely long and thick tongue darted out like a snake and persistently licked up her parched entrance.
"Hieek!? Hnng... ngh...!"
When that wet, rough mass struck her most sensitive clitoris head-on, Celine's body jolted upward.
The Tower Master firmly pinned down Celine's thighs with both hands, skillfully rolling his tongue over her clitoris before thrusting it deep inside her vagina.
"Chureup! Jju-ub, jju-bo-bap...!"
"N-No, I can't...! There... ah! Hnng... hiii..."
Though her mind tried desperately to maintain her reason, the sensitive erogenous zones of a virgin who had never been with a man in her entire life collapsed miserably beneath the Tower Master's skilled and relentless tongue.
Her clitoris swelled red, and copious, sticky lubrication burst from her parched vaginal opening, soaking the Tower Master's chin.
"Look, Celine. Your vulgar hole is already drooling lubrication and soaking my entire chin."
"N-No, that's not it...! It's only... ngh, a physiological reflex...! Hng, uooh...♡"
"Let us see how long those impudent lips can keep making excuses."
While strongly sucking on her clitoris, the Tower Master pushed in his tightly curled tongue and began wildly stirring it around inside her vagina.
"Uaaaaah!! N-No, stop...! My brain, my brain is melting...! Huooh...♡"
Celine's waist lifted into the air and locked in place. Unable even to scream, she merely exhaled breath while barely holding on to consciousness.
She gripped the edge of the bed tightly with both hands, her entire body trembling.
The thread of reason she had desperately clung to in her mind snapped with a soft click.
"Anymore and I... can't... haaah! Uooh...♡♡ I'm, I'm coming...♡"
Celine's entire body stiffened as though electrocuted, and her lubrication burst out in every direction like a fountain.
Having reached her first climax in life through tongue alone, she lay there with her mouth open, drooling and panting harshly.
The Tower Master slowly rose to his feet, licking the fluids from around his mouth.
"Haah... ngh, haah... Is that... enough for you...?"
"My, the main event hasn't even started yet. Get on all fours. Raise your hips high toward me."
The Tower Master roughly stripped off the robe he had been wearing.
Unlike his small upper body, his lower half bore a gigantic, savage cock grotesquely modified with magic, jutting proudly upward with veins standing out all over it.
"W-What is that...? That's not a human size...!"
Celine's pupils trembled with shock.
The monstrously thick thing, easily larger than her forearm, writhed while emitting dark red mana.
"If you want to receive the knowledge of an ancient grimoire, you must endure stimulation of this level. Stop your pointless chatter and push your hips back."
Though her lips trembled with fear, Celine turned around on the bed, driven solely by her determination to obtain the grimoire.
She got down on all fours, lowered her waist deeply, and openly presented her smooth pussy toward the rear, exposed without a single strand of hair.
"What an excellent rear view. That virgin hole winking between your buttocks looks desperate to swallow my cock."
"Hnng... p-please... be gentle... ngh...!"
The Tower Master cruelly gripped Celine's waist and roughly pressed his modified, enormous glans against her narrow entrance, wet with lubrication.
Without any warning, the crude mass violently forced its way in, tearing through the narrow flesh.
Puk―!
"Gy-ahhhhh―!! I-It hurts...!! It's tearing, it's tearing apart...!!"
Her body tried to jerk forward with her scream, but the Tower Master's powerful hand held her firmly in place.
Her crimson pussy stretched as though it would burst, her hymen was brutally torn apart, and thin streams of red blood trickled down the massive pillar.
"Haah...! I can never stop once I feel this narrow little hole being forced open!"
"Nghh...! P-Pull it out...! It's too big...! It feels like my insides are going to burst...!"
The Tower Master lightly ignored Celine's desperate pleas and began a cruel back-and-forth motion.
The enormous pillar filled her completely before pulling out, then slammed back in at a terrifying speed, pounding against Celine's delicate cervix again and again.
"Uooh! Ooh! Ngh...! M-My uterus...! It's being crushed...! Hnng... ahhh...!"
"Endure it! Only by sublimating this pain into pleasure can the mana circuits properly open!"
Chulssak! Chulssak!
The Tower Master's blunt pelvis pounded against Celine's white buttocks so fiercely that they became stained red.
Celine pressed her forehead into the bed as tears poured down like rain.
Under the senseless depth and pressure striking directly against her cervix, the rational identity she had built throughout her life shattered like dust.
"Haah, ah...! No, my brain... it's being filled with the sensation of being pierced by a cock...♡"

"That's right! Absorb the mana through your mucous membranes like that!"
The dark red mana spewing from the tip of the massive cock seared directly into the inner walls of Celine's uterus.
The sensation that had been hellish pain became, as it mingled with the mana, a pleasure intense enough to melt her spinal cord.
Her thighs convulsed madly, and her narrow vaginal walls clenched around the enormous object.
"Hieek...! N-No...♡ I'm becoming strange...! My uterus... it's trembling...♡"
"I'm coming! I shall pour it deep into your uterus!"
The Tower Master's waist drew back as far as it could before striking directly against her cervix with enough force to split Celine's body in two.
Kuung―!
"Kh... hnnng...♡ Haaaaah....♡"

"Take it!"
Byureureureu! Byureut―!
Celine's eyes rolled white as she let out only a series of choked noises. Then she collapsed limply onto the bed, her buttocks beginning to tremble violently.
The modified, gigantic cock filled every corner of her uterus with hot, murky semen.
The semen, mixed with an incredible density of mana, swelled her lower abdomen and forcibly reassembled her mana circuits.
"Uooh...♡ H-Hot...! My uterus... my insides are burning awa—"
Unable to withstand the extreme pleasure and mana overload, Celine finally foamed at the mouth and lost consciousness.
Between her limp legs, virgin blood and semen became entangled and flowed out in thick, gurgling streams.

***
How much time had passed?
"Ngh...."
Celine abruptly opened her heavy eyelids.
Naked on the bed, her lower abdomen was heavily swollen with the semen forced inside her.
Dried bodily fluids and vivid red bloodstains marked the insides of her thighs.
"Are you awake?"
The Tower Master, who had been sitting in a chair, casually tossed a book onto the bed.
It was a leather-bound grimoire exuding an old, ominous aura.
"The Synchronization Ritual ended successfully. Your mana circuits can now contain ancient knowledge. This is the first grimoire I promised you."
Celine somehow raised her aching back and reached toward the grimoire.
The instant her fingertips touched the leather surface, a massive wave of mana surged up her arm and into her heart.
'Th-This is... ancient knowledge....'
Geometric magic circles and spells poured into her mind like a waterfall.
Her vision had entered another dimension, and the mana channels within her body had been opened with exhilarating clarity.
The shame of having bowed like a beast, offered up her uterus, and been ravaged cut straight to the bone, but Celine was not so weak that she would surrender to pleasure and whine like Saintess Maria.
'That's right. This is just a transaction. I give my body as payment, and in return, I gain overwhelming power. I can't become a burden to Ars.'
Celine's cold eyes gleamed as she roughly wiped away the fluids running down between her legs with the back of her hand.
"Indeed... it truly is on another level, Tower Master-nim. I can feel that my realm has risen tremendously."
"Keuheuheu, I'm glad you like it. Once you finish reading that grimoire, you will long for the next volume. When that time comes, come find me of your own accord."
Celine did not answer.
Because she was certain she would return.
