The Princess's Forbidden Diary
Only after the Crown Prince's massive presence had completely vanished from the far end of the corridor did the heavy air crushing the room finally dissipate.
"Haah... Haah..."
I collapsed onto the floor, gasping for breath. My ribs, crushed beneath the corset, were screaming in protest, but something far more urgent demanded attention. My bladder. That insane brother of mine had grabbed and shaken my lower belly so violently that I had been pushed to the absolute limit.
Rustle. The slightest shift of my legs made the thick diaper tucked between them rub against my thighs. A horrific terror gripped me—the fear that I might lose control at any second and soak this fluffy cotton bundle with hot liquid.
"Today's schedule ends here, Your Highness. For a first day... quite a lot happened."
Margareta declared this while pressing a hand to her throbbing forehead. Even the iron-masked head maid's voice carried deep exhaustion.
"Sir Knight, you may take your leave and return to the knights' quarters as well. I shall see you at morning training."
"Yes ma'am! Understood, Head Maid!"
The real princess occupying my original body answered with the crisp vigor of a fresh recruit standing at perfect attention. A man over 190 centimeters tall smiling brightly and bowing politely—it was visual terrorism of the highest order.
Before leaving the room, the real princess glanced cautiously at Margareta, then shuffled hesitantly toward me.
"Um... Your Highness."
She used her massive frame to block the head maid's line of sight, then extended one large hand. Resting on my original rough, callus-covered palm—wrapped in a crumpled napkin—was something.
"You couldn't eat anything during the meal earlier. These are butter cookies I secretly set aside for you. Eat them in secret if you get hungry at night."
My vicious, scar-riddled face was smiling with gentle affection. The unbalanced sight sent chills across my skin, but my stomach had been growling so fiercely after surviving the day on half a macaron that my eyes were drawn to the cookies despite myself.
This bitch... sucking every last drop of honey from someone else's body, but at least she's got a shred of conscience.
To me, those butter cookies were nothing short of salvation. I accepted them with trembling hands. I was just about to thank her when the real princess suddenly leaned in close to my ear. The innocent look in her eyes had vanished, replaced by a hungry, beast-like gleam.
"Um... Knight... I mean, Your Highness. When I go to the knights' order common dormitory... they all strip completely naked and shower together, right?"
"......Huh?"
"Haah... Getting a front-row view of sweaty, muscular men rubbing against each other completely naked! I don't think I'll be able to sleep tonight from all the excitement! See you tomorrow—wink!"
The real princess shot me a revolting wink using my own rugged face, then practically skipped out of the room while humming a cheerful tune.
Bang. The door slammed shut.
I nearly dropped the butter cookie in my hand. My brain had flatlined.
Crazy bitch...? What the hell did I just hear?
Directly watching men strip naked and shower? So excited she wouldn't be able to sleep?
A spine-chilling wave of goosebumps raced across my back.
My precious body. The twenty-year-old macho physique I'd forged through blood and sweat on battlefields since my teens was now being used as a tool to satisfy that perverted woman's lust.
An image flashed through my mind: my original body standing in the knights' shower, ogling the asses and muscles of my mercenary brothers while drooling like an idiot.
"Fuck... No way... What the hell are you planning to do with my body, you crazy bitch...!"
I clutched my head with both hands and screamed.
But no one was there to acknowledge my despair.
"Your Highness. It is time to wash up and retire for the night."
Margareta's cold voice dragged me back to reality.
Wash up. Those words meant removing this damned dress and confronting the horrific truth beneath it.
In the end, I was led by the maids to the bathroom. The instant the corset came undone, the crushing pressure on my organs vanished, bringing a liberating sensation that felt like I might actually survive. But the joy was fleeting.
The utter misery of the maids lifting my skirt and removing the 'daytime diaper' soaked with sweat and bodily fluids defied description.
"You've worked hard, Your Highness. Since you may toss and turn during the night, we will fit you with a nighttime version that has even stronger absorption."
The maids wiped between my legs with completely straight faces, then stuffed an all-white diaper twice as thick and fluffy as the daytime one tightly around my crotch. The soul of a twenty-year-old knight stood there with legs spread like a toddler, entrusting his most private area to them. A thick bundle of cotton filled the space from the cleft of my ass all the way to my lower belly.
I slipped into a soft silk nightgown, but the alien sensation in my lower half could not be hidden. Every step produced a much duller, heavier rustling sound than before.
Rustle. Fluff. My legs refused to close properly, forcing me to waddle awkwardly back to the bedroom. The humiliation was enough to dry up any tears I might have shed.
"Sleep well, Your Highness."
Once all the maids had withdrawn, I was finally alone in the enormous princess's bedroom. Soft magical lights cast an orange glow across the room.
"Haah... This is fucking awful..."
I sprawled out on the fluffy bed. Plop. The moment I lay down, the two heavy breasts freed from the corset spread unpleasantly to either side. The fluffy texture of the thick diaper pressed vividly against my crotch.
I had to find some clue—anything—that could help me overcome this damned situation. Turning over made the rustling sound grate on my nerves, but I forced myself to ignore it and sat up.
There might be something in this room about breaking the curse, or perhaps some weakness of the princess I could exploit.
I began rummaging through the ornate desk with my awkward, waddling gait. The first drawer contained perfumes and jewelry. The second held fancy quills. Then the final, third drawer—one firmly locked with a keyhole—caught my eye.
"Locked? This looks suspicious."
I felt around the drawer and discovered a small key taped to the underside of the desk.
Click. I unlocked it and pulled the drawer open. Inside lay a single luxurious velvet-covered diary and several thick books.
"The princess's diary, huh."
Wondering if it contained some grand royal secret, I swallowed hard and opened it.
Today at the training grounds, Brother Leonhardt and the Knight Commander sparred. The Commander's sword went wide and tore Brother's tunic. The droplets of sweat glistening in that tear... and the Commander's rough breathing. Haah... Watching the two of them exchange those sticky glances, I nearly fainted on the spot. These two are definitely enjoying secret trysts every night!
"......What?"
I doubted my own eyes. Thinking I must have misread it, I quickly flipped to the next page.
If I enroll at the Empire's academy, I'll finally get to see His Highness the Crown Prince, won't I? The rumors say his personal guard knight is an absolute beauty of a boy. The cold-hearted ruler of the Empire and the loyal, beautiful boy knight who obeys him without question! Aah, just imagining it makes me feel like my nose will burst. If only I had been born a man—I could have become a knight and stood guard outside His Highness's bedchamber, eavesdropping on their secret sounds all night long...
"Crazy bitch... She really was a crazy bitch!"
I hurled the diary to the floor. Not a single line about state affairs or worries about high society. It was nothing but the disgusting delusional diary of a perverted woman who did nothing but weave filthy fantasies about the men around her.
With shaking hands, I pulled out the other books from the drawer. Their covers featured lavish illustrations. Two muscular men, shirts removed, were locked in a sticky embrace. The title read: Knights Under the Moonlight: Master, Please Sheathe Your Sword. Subtitle: The Secret Private Life of the First Knight Commander.
"Ugh...!"
A genuine wave of nausea surged up my throat. The cookie I'd forced down earlier nearly came back up. Was I really trapped inside the body of a perverted female like this?
The puzzle pieces clicked into place. Why the princess had eagerly accepted the Royal Head Mage Lazarus's proposal. Why she hadn't screamed in horror at entering my vicious, rugged, macho mercenary body but had instead seemed delighted!
To her, my body was a VIP viewing seat. A perfect identity that would allow her to legally infiltrate the knights' quarters where dozens of sweaty men gathered!
"My body... my precious body... right now in the knights' shower...!"
My imagination tortured me. A vision of the real princess wearing my hideous face, drooling while staring at the bare backs of my mercenary comrades as they showered, played out in my mind like a hologram.
"Noooooooooo!"
I collapsed onto the floor, tearing at my hair. Rustle! Fluff! The impact of sitting down drove the heavy nighttime diaper deep between my legs, crushing my ass. The humiliating sensation stimulating my bladder, combined with the horrific social suicide my original body was likely committing, struck me with both physical shame and mental despair at the same time.
Wearing the diaper, I rolled across the floor of the princess's lavish bedroom, screaming in silent agony. This was a curse. Not just any terrible curse, but a perfect hell deliberately designed by the gods to fuck me over.
