Rigel had carried the girl all the way to the front of the infirmary. There, she had said "U-um... to the restroom..." in a voice so soft and embarrassed that her face was bright red.

That cuteness made even Rigel grin unconsciously. But Rigel was a piece of trash that refused to be satisfied with just that. He had deliberately said "Oh, you want to wash your hands?" and started walking toward the washroom.

"Alright, examiner. Please lead the way."

"Y-yes..."

The examiner obediently started walking. If they kept going like this, they would truly head to the washroom instead of the toilet. The girl, whose urge to defecate was growing stronger by the second, finally gave up and shouted.

"U-um!"

"Hm? What is it? You’ve been saying that over and over."

Rigel turned around. He was grinning.

(Uuu... This is so embarrassing...)

The girl felt like crying from shame. Still, she judged that it was better than being taken to the washroom and leaking there.

(Already... I can’t hold back anymore!)

"R-really... That’s not... I need to go to the toilet..."

"Toilet? Ah, so that’s what you meant by ’restroom.’"

The girl closed her eyes tightly and told Rigel. Just do whatever you want with me!

Rigel looked at the girl while still grinning.

"Hou. So I did something bad."

With those words, he whispered something in the examiner’s ear. It looked like he was giving instructions. The girl didn’t care. Just do whatever you want with me!

"I’ll ask just in case..."

"W-what is it?"

"Do you want to go to the toilet for the small amount, or the large amount?"

"Wha...!?"

The girl’s face turned bright red at Rigel’s words. What should she answer? Lying and saying it was small would be absurd, but admitting it was large was also embarrassing. No, fundamentally—

"I-I don’t need to answer! H-hurry up and take me to the toilet!"

"Easy now. I was only asking a little."

Rigel laughed. He was poking fun at the girl like this.

(W-why is he asking something like that...?)

The girl was bewildered. His behavior was too strange.

"But still... It’s not a meaningless question, right? According to the examiner, there are two toilets near here... The closer one only has small toilets. The second one has both."

"Eh!?"

The girl’s eyes widened at Rigel’s words.

(W-what...?)

She had never heard of such a girls’ toilet. No, but... Could that exist at the Royal Academy? She had heard they had state-of-the-art magical tools as equipment. Perhaps that toilet was one of those?

"The two toilets are in opposite directions. So, what will you do?"

"W-what to do..."

"If what you want is the small amount... then go to the closer toilet. That’s obvious, and it’s faster."

"Ugh..."

The girl couldn’t speak. She wanted the large amount. But telling Rigel that was... embarrassing—

(Y-yes, maybe I should go for the small one after all?)

The girl was torn. Telling a boy her age she needed to defecate was embarrassing. Even more so if it was the large amount. To a girl, that was a line she could not cross.

(Uuu... But still...)

The girl hesitated. If that was an absolute line, then leaking from the small amount might be a line that could be crossed with a hundred steps. But leaking from the large amount... was not.

Just as the girl was hesitating—

Gurururuu!!

Gurururururuu!!

The girl’s stomach let out a scream. Her limit was near. She could no longer hold it.

(Ugh... I can’t anymore... I need to poop! I’m gonna do it...)

The girl resolved herself. She probably couldn’t endure it any longer.

"U-um!"

"Hm?"

The girl spoke to Rigel with a desperate voice. She pushed aside her shame and continued.

"That’s... What I want is the large amount..."

"Got it!"

Rigel answered with a laugh. The girl’s face was red, but she seemed strangely relieved. Then Rigel gave instructions to the examiner.

"Come on. She wants to poop. Take us to the toilet that has both small and large, the far one."

"Y-yes..."

The examiner walked forward, clearly bewildered by the exchange. On Rigel’s back was the girl with a bright red face. She was already full of the urge to defecate and shame. The three of them finally arrived at—

"The girls’ toilet is at the end of the stairs down here."

"Hou, stairs again."

"Eh?"

It was indeed a staircase. Normally, it would be nothing. However, the girl was fighting against an extreme urge to defecate, and whether she could endure it was doubtful. The ultimate battle was about to begin—!

—-

The girl had finally confessed to Rigel that she needed the large amount. With the examiner as supervisor, Rigel carried her piggyback toward the girls’ toilet. However, a major obstacle stood in their way on the path.

"Hmm... Stairs, huh..."

Rigel muttered. In truth, going up and down stairs was unexpectedly heavy and dangerous. If an elderly person slipped and fell badly, it could even be fatal. Even middle-aged people often ran out of breath and panted when climbing. Young people were fine in normal conditions, but carrying someone else on their back made it a completely different story.

"U-um... Are you okay?"

"Hm? What do you mean?"

"Th-that, carrying me down the stairs..."

"No problem. I just showed you that I could go up the stairs earlier. It’s the same thing."

"I-is that so..."

The girl asked worriedly. Rigel laughed. In terms of physical exertion, going down was actually easier than going up. However, descending stairs had its own dangers.

"Oop..."

"Hyauun! Haa, haa..."

Rigel carried the girl down one step. The vibration alone was heavy enough that the girl let out a voice. —Just as I said, each step down sent a greater shock. Even if it wasn’t an issue in normal times, that impact was unbearable when she was at her absolute limit with the urge to defecate.

"Oop... Haa..."

"Kuu! Fu!! Haaan!!!"

Rigel descended the stairs one step at a time. He went slowly enough that the girl wouldn’t leak in one go, but fast enough that it still made her cry out from the shock. Thanks to his exceptional physical ability thanks to the cheat skill [Rape], the girl continued to receive the perfect amount of impact on her body.

"Haa... Haa..."

"..."

The girl being carried piggyback was out of breath. She had no energy left to make sounds. Rigel smirked inwardly. They had descended about half the stairs from the third floor to the second. They reached the landing, and the girl finally felt a small sense of relief.

"A-um..."

"Hm?"

The girl spoke to Rigel in a trembling voice. It was incredibly weak.

"It’s... almost at my limit..."

"Hou?"

The girl’s stomach was screaming. She had no more leeway left.

"That’s... For now, go even slower—"

"I understand. You’re in a hurry, aren’t you? Let’s descend faster!"

"Eh?"

The girl’s eyes widened. Rigel had ignored her request. Or rather, he hadn’t ignored it — he had simply misunderstood without any malice.

"Hold on tight, okay?"

"Eh... N-no—"

The girl tried to protest, but it was already too late. Rigel began descending the stairs faster. Previously he had gone down one step at a time slowly. Now he was skipping steps.

"Hii! Naa!!"

"Don’t worry. We’ll make it!"

Rigel said confidently. —When someone was at her absolute limit with the urge to defecate, what was the ideal speed for descending stairs? The faster, the shorter the time, but the greater the impact. The slower, the less impact, but the longer the time. It was a balance between time and shock.

The girl wanted to endure with as little shock as possible, even if it took a little more time. However, Rigel had deliberately misunderstood her request and accelerated instead.

"U-um... I-I think it’s already enough! Go slower... Hyaaan!?"

"Sorry. You’re probably close to your limit, aren’t you? Do your best!"

Rigel encouraged her with a very cheerful tone.

(Why!? Why is he misunderstanding even now...?)

The girl despaired. Even though she was already close to her limit...

"Look, we’ve reached the second floor from the third. That’s half way. Now we just have to descend from the second floor to the first."

"Uuu... It’s still half... I-I... I’m gonna poop..."

The girl’s stomach had already exceeded its limit. She was about to leak at any moment.

"Don’t worry! I have a secret weapon! We’ll make it!"

"R-really...?"

The girl clung to Rigel’s words. There was no other way for her now but to trust his so-called ’secret weapon.’

"Aah, leave it to me! Here we go... Woaaa!!"

"... Eh?"

The girl felt a floating sensation. For a moment she didn’t understand what was happening. But a second later, she realized.

Rigel carried her piggyback, and with a leap, he jumped from the second floor directly to the landing between the second and first floors.

"Hii!? I-it’s no good...! This... this..."

The girl let out a despairing voice. Even when he had descended one step at a time, it had been extremely difficult. When he started skipping steps, she was already at her absolute limit.

And now he was jumping ten or more steps from the second floor to the landing...

"N-no... Noooaaaaaaaaaaaaa!!!"

The girl screamed, imagining her own future. But gravity was merciless. Rigel’s body carrying the girl was sucked straight into the landing.
