His voice pleaded desperately. Cecil stared at his brother for a long time with a dreamy face before embracing his neck. His head nodded slightly.

At that passive permission, Cyrus smiled, got up from the bed, and spread Cecil’s legs wide. After positioning him in the usual manner for taking his c*ck, Cyrus rotated his hand to gradually expand the hole.

“Aah!”

Unable to bear the sensation, Cecil screamed and kicked his legs into the air. Then, whimpering, he grabbed the back of his knees himself and looked down. Cyrus gently caressed Cecil’s b*ttocks, treating him like he behaved well, spread all the flowing love juices on his hand, and began to thrust his four fingers in deeply.

“Ah! Ah! Ah!”

The speed exceeded the usual pace. With each thrust, love juices splashed everywhere, staining Cyrus’s lips and neck. In that state, Cyrus spread his fingers like scissors to widen the inside, then gathered his thumb with his four fingers. As he slowly pushed his hand, formed into a point, inside, Cecil began to sob with screams.

“Ah, hngh, ah, ah, stop, mmng!”

Despite the pleas to stop, Cyrus continued. The sound of stretching skin filled the air, and at the moment the thickest protruding joint caught on the hole.

Thud!

“……! Aaaah!!”

Cyrus forcefully pushed his fist inside. Even when Cecil tensed his entire body and thrashed his legs wildly, Cyrus persisted. Instead, he gathered Cecil’s legs together, hung them over his shoulder, and adjusted his position to make fisting easier.

“It’s all in.”

“Hic, sob.”

The hole had completely swallowed his wrist. A wrist twice as thick as an average adult male’s c*ck stretched the p*ssy extensively. Cyrus held his brother to prevent any movement and began to explore the inner walls.

He felt the soft, convoluted inner walls. This place welcomed his g*nitals’ entry and exit. The inside felt moist and soft, and he detected a thickly fleshy point. This spot made Cecil release urine when crushed.

“Brother, you like it here, right?”

Asking that, Cyrus pounded the thickly raised spot with a thud!

“Aah! Huaah! Aaahng!”

“When I pound here, you piss yourself. Brother, right?”

Thud, thud, thud, thud!

His fierce fist pounding hammered Cecil’s p*ssy passage. Cecil shook his head and tried to escape the fisting, but his efforts proved futile. His legs, held immobile, might have been tied with wire.

He felt his mind slipping away from the frenzied pounding. Saliva dripped from his mouth and physiological tears poured out. He wanted to tell him to stop, but his tongue tip only trembled outside, unable to form words.

“Brother’s p*ssy, f*ck, how convenient is it to have this kind of spot here? Huh?”

“Ugh, ah! Hng, nghh…!”

Cyrus also lost himself in his own way. To think that someone with such a proper appearance had an erogenous zone in such a shallow place—it seemed cheap and easy. The fact that this person was his own brother made Cyrus feel his head would explode. So he freely pounded the inside with his fist, thoroughly violating the spot where Cecil writhed.

Thud, thud! Thud!

After several pounds, Cecil released watery s*men resembling urine. Sweat also flowed down Cyrus’s forehead. But he had no intention of stopping here. Cyrus gently caressed the inside and inserted his arm deeper and deeper.

“Ah, w-wait, just…”

Surprised, Cecil touched his lower abdomen and found it bulging near the navel. Looking down in bewilderment, he saw the arm had entered past the middle of the forearm.

“Ah, no. Stop, okay? Stop…”

Despite his fearful pleading, Cyrus, with a cold look in his eyes, showed no intention of stopping. And just before the word “stop” escaped Cecil’s lips again, Cyrus clenched his fist and pounded the inside with a thud! It struck the entrance to the colon.

“Huaaaah!”

This spot ranked as Cecil’s favorite, and when this entrance opened, he would burst into tears while spurting transparent fountain water and urine wildly. When Cyrus crushed this spot with his gl*ns and acted recklessly, he felt frustrated for not having fingers at the tip of his c*ck.

“Brother, feels good? You’re pissing.”

True to his words, a cloudy stream of water flowed from Cecil’s c*ck as his bladder received stimulation. Cyrus mocked the sight and pounded with his fist at a rapid pace. The delicate colon endured crazy pounding, and the inside gradually opened up. Cecil’s screams also grew increasingly louder.

“Ah! Ah! N-no! Aaahng! Ahng! Ng!”

Thud! Squelch, squelch, thud!

p*ssy juices completely caked his forearm, creating a mess and emitting a fishy smell, but Cyrus didn’t care. His only thought focused on penetrating his brother’s colon with his fist. So as he mechanically pounded, the colon began to open little by little. Cecil’s crying also intensified.

Before he realized it, his arm buried itself up to where the forearm bends. It seemed with just a little more effort, the colon would open wide and accept Cyrus. So Cyrus pulled his arm back as far as possible and forcefully pounded the colon with a thud!

“Aaah!”

And once more, pulling his arm back and finally burying it all the way to the elbow, the colon opened wide and completely enveloped Cyrus’s fist.

“Huaaaah!”

Cecil’s eyes widened enormously, and his buttock flesh trembled. The expanded colon twisted wildly and convulsed, and Cyrus’s fist became drenched in the gushing love juices.

Cecil’s lower abdomen bulged in the shape of a fist as it took his brother’s forearm. The sound of urine bursting forth echoed again.

From that position, Cyrus thoroughly crushed the colon with the bulging joints of his fist. He wanted to ensure Cecil would never forget his mark. He left his trembling brother in place and pulled out his forearm. A sour and sweet smell emanated from his arm.

The hole gaped wide enough to see clearly inside. Cyrus hurriedly thrust his er*ect c*ck into it, moved his hips a few times, then grabbed one side of Cecil’s dazed face and rubbed his cheek. He wanted to piss inside Cecil. He wanted to mark him so that he would recognize it was his from anywhere.

So he didn’t hold back and released his lower abdomen while sucking on his brother’s lips.

Shhh…

The held urine burst forth, and the expanded hole couldn’t contain all the urine, causing it to leak outside, but Cyrus still felt satisfied.

“Brother, I love you, I love you, I love you.”

Pouring out insane confessions, Cyrus completely filled his brother’s p*ssy with urine. This beautiful, fair thing belonged to him. His possession.

“You’re mine, brother. Right?”

As he asked obsessively, staring down at Cecil, he could see the half-unconscious Cecil’s pupils following Cyrus. Cyrus lowered his gaze toward Cecil seemingly wanting something.

“Answer me.”

Cecil, whose entire body soaked in urine and love juices, raised his weak arms to embrace his brother. Then he slowly nodded. At that answer, Cyrus sighed seemingly having solved a long-standing problem and hugged Cecil back.

This fair and beautiful thing. Something no one should take away.

The only owner of his brother was himself.

Apart from the deepening relationship between the two, life at the academy continued normally. The only differences involved quietly holding hands during class or Cyrus enjoying stolen kisses in empty corridors. Cecil sometimes felt his heart flutter at the precariousness but adapted to Cyrus’s actions.

“Cyrus, Professor Langshir is calling for you.”

The three siblings had met after a long time and enjoyed a light picnic when this happened. A male student who occasionally crossed paths with them approached and called for Cyrus. Professor Langshir taught philosophy and particularly adored Cyrus, constantly trying to draw him into the academy’s advanced program.

Even though he remained only a first-year student, the professor already desperately wanted to take him as a disciple. Cecil found Cyrus’s talent both amazing and quite troublesome.

“Go ahead, brother.”

“Hah…”

Cyrus got up abruptly, running his hand through his hair in irritation. He already felt on edge trying to avoid the professor, and this truly represented an exhausting encounter. Despite making it clear that he had absolutely no interest in the advanced program, the professor kept calling him, offering food and drinks, and questioning his assignments—why did you think this way, why did you answer that way—it exhausted him to death.

“Brother, I’ll be back.”

“Am I invisible?”

“Sister too.”

After Cyrus reluctantly greeted them and disappeared, only the two remained. Having the two siblings alone after a long time, Alesia seemed pleased as she lay down using Cecil’s thigh as a pillow and hummed a tune.

“How have you been lately?”

“About what?”

“Just everything. You must have a girlfriend now, so there must be big changes in your life?”

As the expected topic arose, Cecil smiled.

“It’s the same, nothing’s different.”

“You always worry me like a child left by the riverside.”

“Seriously… Sister is worse.”

Thinking about who really worried about whom, Cecil let out a silent laugh, and Alesia twirled a foxtail grass she had picked from somewhere.

“Tell me about your girlfriend.”

“What about her… There’s nothing to tell.”

“Come on, is she pretty? Is she nice? Is she tall? Who is she that you won’t even tell me about her!”

Alesia, who had been lying down, suddenly sat up and grabbed Cecil’s shoulders. Knowing Alesia, who persisted tenaciously once she latched onto something, Cecil looked troubled.

He had never excelled at lying. He preferred to keep his mouth shut rather than lie, but now he didn’t even have that option. The moment he clamped his mouth shut like a clam, Alesia would force it open to get an answer.

“…Just, pretty and tall.”

Having endured torment to tears just the night before, he couldn’t bring himself to say she was nice.

Seeing her brother’s face redden at just those few words, Alesia made a curious expression.

“What year is she in? Same as us? One year above?”

“Why do you keep asking…”
