Using the Shared Bathroom

At 10:30 p.m.

In the room, Akira taught Itsuki to study as usual.

"Well, to solve this problem, use this formula, then the result will be fulfilled. Itsuki-Nee understand?"

"Hmm?"

Hearing no response, he turned his head and saw that Itsuki had fallen asleep sitting up.

"It turned out to be past her bedtime, I didn't realize it."

Glancing at the clock on his cell phone, Akira realized that it was past 10 p.m.

"Wake up, Itsuki-Nee, sleep in your room."

"..."

He tried to wake Itsuki up, but to no avail.

"Sigh~ Once she's asleep, even an earthquake won't wake her up."

He sighed, not knowing whether to take this as a good or a bad thing. If someone was taking advantage of Itsuki while sleeping, she might not even notice.

Akira placed his hands between Itsuki's thighs and back, and brought her into a princess carrying position.

"Itsuki is heavier than the other twin sisters."

Weighing Itsuki in his arms, Akira who had experience carrying Ichika, Nino, Miku, and Yotsuba. He had to admit that Itsuki was the heaviest among the quintuplets. Of course, this weight meant nothing to him.

He walked steadily without faltering or shaking, opening the door, he walked down the hall. When passing Miku's room, the door suddenly opened.

"What's wrong with Itsuki?"

Miku's sleepiness disappeared when she saw Itsuki in Akira's arms, she thought something had happened to her.

"Itsuki-Nee fell asleep while studying, I'll take her to his room. Miku hasn't slept yet?"

"Don't call me that, what if Itsuki hears it."

Miku panicked at hearing Akira just call her name, and looked around.

"Take it easy, Itsuki-Nee sleeps like a corpse. She won't wake up before morning." Akira said very sure.

"But, that doesn't mean you're being reckless. Maybe someone is listening."

Miku is restless and worried, the feeling of guilt has crossed a line that should not be crossed, has given her mental stress.

"Wait here, I'll be right back."

Not waiting for Miku to give an answer, Akira rushed into Itsuki's room.

After putting Itsuki on the bed, covering her with the blanket, turning on the air conditioner, and closing the curtains.

A few seconds after Akira left the room, Itsuki whom she thought was sleeping, opened her eyes.

"Akira called Miku by name only, and Miku's voice sounded abnormal... What happened to the two of them?"

"Akira thinks I won't wake up even if an earthquake happens, does he think I'm a pig?!" Itsuki muttered complainingly.

When Akira taught her, she did fall asleep. But she wasn't completely asleep, just barely asleep.

When hugged by Akira, Itsuki really enjoyed it, and decided to pretend to be asleep. Her act almost failed when she heard her little brother say she was heavy. But, somehow she managed to keep from opening her eyes.

The ambiguous conversation between Akira and Miku, which shocked Itsuki the most.

"What exactly happened... Hoam~..."

Drowsiness overcame curiosity, after yawning, her eyelids felt very heavy, and Itsuki fell asleep.

On the other hand.

Closing the door to Itsuki's room, Akira found Miku standing in front of her room door. Then, he approached her.

"I want to do that, tonight, is that okay?" Akira whispered in Miku's ear.

Miku understood what Akira wanted to mean, her face turned bright red, and she nodded slowly.

"En."

Gaining the other party's approval, Akira gave a small smile. Holding Miku's hand, he dragged her into the room, and made sure to lock the door so that Yotsuba incident wouldn't happen again.

"Ahn~ Slow down..."

"Ssss... Hold your voice, someone will hear."

"Whose fault does Akira think it is, ah~..."

From behind the door, came the sound of sighs and other strange sounds.

...

At 5:30 a.m.

Akira woke up by his physiological alarm, felt the weight on his arm, looked to the side, and saw Miku using his arm as a pillow.

He pulled his arm slowly so as not to wake Miku, got off the bed, and picked up the clothes scattered on the floor. Then, he used [Hiraishin no Jutsu] to return to his room.

Taking advantage of everyone still sleeping, Akira took a bath to dissipate the scent on his body.

"Who is inside?"

A woman's voice came from the bathroom door.

"It's me, Nino-Nee."

Akira instantly knew the girl's identity just by sound.

"Why are you taking a shower so early."

"I forgot to turn on the air conditioner, my body is sweating. So I'm taking a shower, Nino-Nee what do you want?"

"Toilets, quick. I can not stand it anymore."

"OK, wait a second."

There was still a lot of shampoo foam on his head, Akira stood up, and opened the bathroom door.

Nino was wearing purple pajamas, her long hair was left loose, and her usual bow bow was nowhere to be seen.

"W-Why are you naked!"

Nino's eyes opened wide, and she raised her hand to cover her face. But, there was a gap in her finger.

Even though she was nearsighted, that didn't mean she couldn't really see. Akira's naked figure was so clear in her eyes, especially seeing the large object hanging from his crotch, her face was as red as an apple.

"I took a shower, isn't it natural to be naked?" Akira said make sense.

"At least use your towel when opening the door." Nino looked through the gaps in her fingers.

"I was washing my hair, Nino-Nee said she couldn't stand it anymore. So, I acted quickly."

"Akira..."

Nino was touched by how much her little brother cared about it. Her anger subsided, and did not become angry.

(Too easy...) Akira thought.

"I'll go out first, Nino-Nee use the restroom, call me when you're done."

Just as Akira stepped forward, Nino held her hand, and pretended to be brave.

"Don't go, you should rinse the shampoo off your head. If not, your hair can be damaged later. Let's use the bathroom together."

"Okay."

Akira agreed, he went back to the bathroom, turned on the faucet, and started rinsing his hair.

(There's nothing to be afraid of, as kids, we used to bathe together. It's just a trivial matter.)

Nino took a deep breath, convinced herself, and went into the bathroom.

Standing in front of the toilet, she hesitated, turning back, she was relieved Akira didn't notice her.

"Akira, don't look over here."

"I know."

"Also, cover your ears."

"Why?"

"Just do it!"

"Hai, Hai, Hai."

Seeing Akira cover his ears, Nino pulled down her pants and panties, the cold sensation of the toilet on her butt, made her body shiver.

"This is weird, why won't you come out?"

Nino is nervous, her urine won't come out!

"Have you done it yet?" asked Akira.

"Don't turn around!"

Nino bit her lip, and forced the urine out. After being pushed, the urine finally flows out and falls into the toilet.

"Haaahhh... So comfortable~."

She breathed a sigh of relief as she closed her eyes. Nino forgot her little brother was in the bathroom.

After peeing, she flushed the toilet, and said to Akira.

"It's done, don't tell this incident to Ichika and the others."

"Why?"

Akira acts like an innocent child.

Nino gritted her teeth, her face was bright red, stomping her feet, she said threateningly.

"Just don't tell anyone. If not, Onee-chan will throw the Gundam in your room into the trash."

"Nino-Nee dare?"

Turning to face Nino, Akira looked at her while narrowing his eyes.

Nino subconsciously took a few steps back, she was intimidated by that look in his eyes, this was the first time Akira acted like this towards her.

"Nino-Nee, just calm down. I won't tell anyone about this."

Feeling that he had gone too far, Akira returned to his cute little brother appearance.

"Remember that."

When Nino left the bathroom, Akira's domineering appearance gave her a new sensation.

Akira didn't know that he had awakened a new character in Nino, after rinsing his hair, getting into the bath and taking a bath.
