I was so stupid. Truly.
I only thought about testing his limit... I didn't realize... he's bottomless!
Kei Shirogane lay on Moeha's bed with hollow eyes, that single thought looping in her mind. It wasn't until she heard the voices of the Fujiwara sisters and Rin that she snapped out of it.
She sat up abruptly and stared blankly at the three people by the bed. As their gazes landed on her, she finally realized how pathetic she looked.
She looked like she had just been fished out of a pool. As for what kind of pool... hehehe.
Moeha winked at her with a face full of mischief.
"I called in sick for you so you could rest... I didn't think you'd be 'snacking' on your own."
"N-no... it's not like that."
Facing Kei's weak defense, Moeha just blinked. That suggestive look made Kei want to crawl into a hole. She was nothing like the cold beauty she pretended to be at school.
Kei knew that no matter what she said, in Moeha's eyes, this was a secret tryst.
"I-I-I'm going to take a shower."
Guilt-ridden, Kei bolted from the room like she was escaping a crime scene, leaving a trail of sticky footprints behind her. Moeha didn't follow; she just called out that she'd prepare a change of clothes for her.
Kei stayed over at the Fujiwara house often enough to have a wardrobe there. Her father and brother hadn't suspected anything when she didn't come home last night.
In the bathroom, Kei looked at her reflection and turned a deep shade of crimson. Her silver hair was matted into clumps.
When it was fresh, it looked erotic, but now that it was half-dry, it was a bit crusty and gross. But that wasn't the main issue. Her gaze fell on her lower abdomen, which was visibly distended.
Though their apartment was small, Kei did yoga-like stretches every day; she was flexible and had zero body fat. The only reason her stomach was bulging...
Was because it was filled to the brim.
Kei squatted in front of the mirror and opened her legs. The warm, fresh fluids preserved inside her body began to drip onto the bathroom floor. If Moeha saw this, she'd scream about the waste.
It wasn't that Moeha liked "eating" it, but doing so in front of Kei or Kaguya would make them make the most adorable, shamed faces.
After taking a breath, Kei clenched her fists and tightened her core.
Squelch...
A massive puddle instantly formed beneath her.
But it wasn't enough. Kei pressed hard on her own stomach.
The stuff in her rear came out easily enough, but the front... no matter how hard she pressed, she couldn't get it all out. Her female instincts were trying to lock his essence inside to conceive the next generation.
Even though she had taken the "medicine" Rin gave her, she couldn't get past the psychological barrier. She felt like she could feel every individual "tadpole" slamming against her delicate internal walls.
I won't get pregnant. If it were that easy, Chika-senpai and the President would have had babies long ago.
After comforting herself, she stood up. She couldn't get the inside clean, but she could at least wash the outside.
Big Brother is too much... making me this messy.
But... is it just my imagination? My skin feels smoother and more moisturized than ever.
Imagination. Definitely. How could this stuff possibly nourish skin!?
She shook her head to clear the weird thoughts and turned on the shower. The warm water hit her body.
"..."
She squinted in pleasure and turned around, letting the spray hit her face to wash away the grime. After a long rinse, she grabbed a towel to wipe her face.
When she opened her eyes, she noticed white, stringy flakes on the towel.
"...Mmm? What's this?"
Kei frowned, examining the stuff. It looked like the cooked egg-whites in an egg-drop soup. Where did it come from?
Then she saw her reflection in the mirror.
Why is there stuff in my hair too—!?
It wasn't just her hair. It was on her body and the floor.
Finally, she realized what the "egg flakes" were. It was all protein. Rin's fluids were essentially like egg whites.
When you put egg whites in hot water, they clot into flakes.
"AAAAAAAAAAHHH!!!!"
What am I thinking!!!!
Damn it!! I'm never letting him get it in my hair again!!!!
She pulled her silver locks forward. The "egg flakes" had practically glued her hair together; it was slick, sticky, and disgusting. She wanted to cut it all off.
But cutting it wouldn't help. It was stuck to the roots. Unless she went bald, she was stuck.
She could clean the tips herself, but the roots...
Kei, close to tears, cracked the bathroom door open and screamed.
"Moeha! Chika-senpai!!! Come to the bathroom!" Her face was burning. "Big Brother! Stay away!"
The Fujiwara sisters, guessing exactly what was happening, suppressed their laughter. They grabbed a change of clothes and walked into the bathroom completely naked.
Seeing the white flakes in her silver hair, Moeha and Chika burst out laughing.
"Oh dear, it's Sis's fault for forgetting to tell Kei-chan not to use hot water on her hair."
"Eh? My fault?"
Kei glared at Moeha with shame and fury. They had definitely dealt with this before!
"Stop talking! Just help me clean it!"
Kei was on the verge of crying. If she didn't get it clean, she was doomed at school tomorrow! Forget school—if her father or brother found out tonight, her life would be over.
They'd never let her move into Big Brother's studio.
"Don't worry. Sis and I will get you sparkling clean."
Moeha brought a small plastic stool and had Kei sit. The sisters sat on either side of her.
Chika expertly squeezed shampoo into her hands, lathered it, and applied it to Kei's head. They did a quick rinse with cold water first, then began to meticulously pick out the clotted flakes hidden in her strands.
"I heard you're going to manage Big Brother's desires?" Moeha said while picking out a flake.
"It's mostly to manage you two! Big Brother... Big Brother is bottomless."
Kei still felt a lingering fear. The amount he had glazed her with... it felt like he had shot out his entire brain. But he was perfectly fine, and the cum never even thinned out!
Is he even human!?
"Eh? Kei-chan, why are you calling him Big Brother too?"
"Uuu..." Kei lowered her head in shame. "Calling him Mr. Rin was too formal... I just... copied you."
"Oh? Just copying me? I thought maybe you had actually fallen for him."
"I... I have NOT!"
