“Let me sleep! I just want to rest!”

“Didn’t you say you had insomnia? After s*x, you’ll be tired enough to fall asleep quickly.”

“Who do you think is causing my sleeplessness in the first place…!”

Each day was a continuous state of exhaustion. Though less painful than at first, Diego’s manhood remained overwhelming.

Prince Isaac slowly looked Siara up and down.

“I still don’t understand why Diego is so obsessed with you.”

“…Neither do I.”

“You’re nothing special.”

“…”

Annie was somewhat plain. But Siara’s original appearance had been that of a beauty with milky skin and ebony-black hair. A beauty who captivated anyone who laid eyes on her.

Siara’s lips jutted out in a pout. But what could she do? The real owner of her body was living well elsewhere, while her own body had been struck by lightning with unknown consequences.

“Since Diego likes you so much, I’d like to sample you too.”

“…What?”

Did he just say what she thought? Siara asked with wide eyes. Prince Isaac moistened his lips with his tongue and spoke in a low voice.

“If you give yourself to me, I’ll give you whatever you want.”

“…Really?”

Siara immediately thought of the Imperial Library, accessible only to the royal family. If she just closed her eyes and endured it once, she could perform dimensional transfer magic. Then she could return to the Kingdom of Estain!

Seeing Siara’s positive response, Prince Isaac burst into laughter.

“Hahaha! Diego must truly have his eyes on his feet! Hahahaha!”

When he laughed loudly, people’s attention turned to the two of them.

Diego, dancing with another noble woman, glared in their direction. The Empress also frowned, staring at Isaac and Siara.

Siara stomped hard on Isaac’s foot.

“Ugh.”

Only then did Isaac’s laughter stop. Siara said to him:

“Let’s go now.”

“…Where to?”

“To the Imperial Library.”

“Ah, you like having s*x in the library? All right.”

‘Like h*ll I would, you child.’

Siara stood up abruptly, but felt a strange sensation between her legs. Fearing the device inside might slip out, she walked slowly while clenching her muscles.

Diego would likely be trapped by the Empress, forced to dance with every woman present.

‘Now’s my chance!’

“Shall we go then? Before someone interferes.”

Isaac moved toward the Imperial Library. Siara followed him with an unnatural gait. Had there not been a strange device between her thighs, she could have easily kept pace with Prince Isaac.

With each step, the device poked deeper inside her, driving Siara to the brink of madness.

“Hm, nngh…!”

Hearing her strange moans, Prince Isaac gave her a surprised look.

“…Quite eager, aren’t you? We haven’t even reached the library yet.”

“That’s not it…”

Prince Isaac stopped, entered a grassy area, and beckoned to Siara.

“If you’re that desperate, how about doing it here?”

‘Do you want to die?’

She barely managed to hold back the words that nearly escaped her lips. The Imperial Library was just a little further. If she could just get there…

“Still need to get to the… library…”

“You don’t like outdoors, I see. Well, you were a noble lady despite being illegitimate, so that makes sense.”

Prince Isaac muttered as he came back out. He snickered at Siara, who was squirming uncomfortably.

“…Want me to touch you?”

“No. I’m… hngh, fine.”

“It doesn’t look that way.”

Suddenly, Prince Isaac pushed her against the wall. His knee pressed between her thighs, pushing the device deeper inside.

“Agh…!”

Prince Isaac whistled while repeatedly pressing his knee upward. Siara rested her head on his shoulder, biting her lip.

“Ah! Hngh, mmm…! Stop…! Hah!”

“…You’re quite sensitive. I heard you both were each other’s first… Wait a moment.”

“Haa. Haa…”

Prince Isaac stopped pressing with his knee and rubbed her undergarments. Then he slipped his hand inside and pulled out the phallic device. It was slick and wet with her fluids.

“So this was the reason?”

“Hngh…”

This was embarrassing. Of all things, to be discovered carrying such an object.

Prince Isaac licked her neck with his tongue.

“Pervert.”

At his words, Siara’s face turned bright red. Prince Isaac curled his lips into a smile and gripped her wrist tightly.

“Let’s go to the Imperial Library. You must feel empty now that the device is gone. I’ll fill you thoroughly once we get there.”

“…!”

She wanted to shout that she wasn’t a pervert, but getting to the library took priority.

Prince Isaac threw the device into the garden. Now able to walk more comfortably, Siara looked back. She wondered if Diego might be following them, but he wasn’t there.

‘…I suppose the woman who could become Empress is more important than me.’

Had she grown attached? She kept looking back. Yet once she completed the dimensional transfer spell, she would leave this place.

She practically ran to keep up with Prince Isaac’s pace until they reached the Imperial Library.

Prince Isaac chased away the archivist and others. He closed the door and began removing his pants.

“Shall we do it right away?”

His manhood stood er*ect, seemingly quite excited. Looking at him with his pants off, Siara smiled brightly. However, contrary to her smiling face, her words were not so pleasant.

“Go f*ck yourself, you lunatic.”

“What…!”

As the enraged Prince Isaac lunged toward her, his mouth and body froze solid. The prince rolled his eyes in panic. His body was frozen so completely that only his eyes could move.

Siara climbed a ladder and searched where she had seen the archivist retrieve books earlier. She quickly found all the books containing dimensional transfer formulas.

She checked to make sure Prince Isaac was staying put, only to see his exposed manhood glistening inside the transparent ice.

“…Smaller than Diego’s.”

“…Mmph!”

Ignoring his muffled protest, she sat at the desk and opened a book. It contained only miscellaneous knowledge about dimensional transfer.

‘Not this one…’

She discarded one book and picked up another. As she was eagerly scanning for anything resembling a formula, the Imperial Library door burst open.

“Huh…?”

Diego, radiating murderous intent, first saw the frozen Prince Isaac, then locked eyes with Siara. He frowned at the book she was reading.

“Ah, this is…”

Feeling guilty, Siara closed the book. But as she did, the title “On the Formulas of Dimensional Transfer” became clearly visible on the cover.

Suddenly, two of the books Siara had began to burn with a whoosh. Diego had undoubtedly used his power.

“Wait…! Diego!”

Siara quickly froze the remaining book to prevent it from burning. However, the other two instantly turned to ashes.

Siara was flustered. Perhaps because this wasn’t her original body, she couldn’t fully manifest her power. The energies of the two mages clashed head-on.

Fire and ice—normally an exciting duel, but this was not the time.

Siara rapidly turned the frozen pages one by one. If this book didn’t contain the formula, all would be lost.

‘If I lose this book, I can’t go back! Then I might have to be Diego’s night companion forever!’

Then she saw it—the formula. As the formula reflected transparently in Siara’s pupils, she cast the dimensional transfer spell.

“Siara!”

Diego’s desperate voice reached her ears. As she chanted the spell, a pitch-black hole appeared, and Siara was sucked into it.
