"I feel like I'm about to overflow already."
"...?"
He just gave Chika and the others so many loads last night, and he's already recovered!?
I don't believe it!
Kei stared at Rin's mischievous expression with a stern face.
He was kind, yes, but he was also a total sex addict.
She was annoyed! Very annoyed!
Even if his drive was strong, he needed to take care of himself. If his body collapsed, everything would be over.
"Didn't I just say you need to be careful with your health, Big Brother? If you're going to lie, at least make it believable! How could you be full again after last night?"
"If you don't believe me, why don't you test it, Kei? If I'm empty, it'll come out clear like water. Besides... if you're going to manage my desires, you need to know where my limit is. Everyone's constitution is different, right?"
Kei bit her lip. Under Rin's gaze, her face went from pink to scarlet to a deep, heated red. After a long hesitation, she finally nodded.
"Fine... I suppose that's true... Ah~!"
The moment she agreed, Rin scooped her up and tossed her onto Moeha's bed.
She pursed her lips and turned her face away, avoiding his eyes. Her silver hair fell over her cheeks, some strands caught between her lips. She didn't cover her small breasts or her crotch; instead, she gripped the bedsheets tightly with both hands, enduring the shame.
"Just this once... only to test your limit. N-never again. From now on, I'll only help you process your desires normally."
"In that case, you better keep a good count, Kei." Rin winked. "You only lost your virginity last night, so you're probably still sore. Let's use other places to test the limit today."
"Other places?"
"For example... your mouth."
Kei remembered the image of Kaguya and Hayasaka serving him together last night. She closed her eyes and parted her lips slightly.
"I... I don't have all the skills President Shinomiya has. Just... do whatever you want."
Afternoon.
Back at the front door, Moeha grabbed Chika's hand as she reached for the handle. She looked at her sister with the eyes of a cunning little devil.
"Sis, do you think Big Brother and Kei-chan are still inside? Want to make a bet?"
"What kind of bet?"
Chika agreed without a second thought. She lived for games like this.
Moeha's gaze dropped to Chika's chest.
"I bought a breast pump. If you lose, I get to use it on you for an entire hour!"
"Wh-when did you buy something like that!?" Chika's face filled with shock before she shook her head frantically. "Y-you've definitely planned this. No bet! No bet!"
"Ehh..." Moeha put on a pitiful, pouting face. "But Sis, you already agreed."
"I... I'm not betting!" Chika was wavering under Moeha's kitten-like eyes, but her survival instinct kicked in. No way! If she bet, she'd definitely lose!
"Tch~" Moeha clicked her tongue, but she wasn't actually upset. Hehe... Sis is so naive. Does she really think she can escape the pump just by not betting?
Giggling...
Bet or no bet, she's getting pumped!
They pushed open the front gate, crossed the yard, and opened the front door. Immediately, they saw two pairs of shoes in the foyer. They hadn't left yet.
"Lucky I didn't bet... Moeha, did you put a camera in your room?"
"Ehehe~"
Seeing her sister dodge the question with a 'moe' act, Chika knew for sure there was a camera. Betting with her was a one-way trip to being bullied!
"What are they doing? Still sleeping?"
"Hehe... you'll see in a second, Sis." Moeha made a shushing gesture and tiptoed upstairs toward her room.
At the door, Chika didn't open it immediately. She pressed her ear to the wood. She heard nothing for a long time.
Since there was no sound...
Chika took a deep breath and shoved the door open.
"We're ho— HISS!!!"
The scene in the room—especially the state of Kei Shirogane on the bed—made Chika suck in a sharp breath.
Even Moeha, who had seen snippets through the camera, was stunned seeing it in person.
Kei had been "whitened" by Big Brother!
Not in some metaphorical sense, but literally.
Kei was entirely covered in white. Last night she had a "facial mask," but now her entire body was glazed. Every inch of her skin was coated in a thick layer of Rin's fluids. Even her beautiful silver hair was matted and soaked, as if she had just taken a swim in a pool of Rin's semen.
She was messy on the outside, and surely even messier on the inside. Her stomach was even slightly bloated from the amount he had pumped into her.
She lay there with vacant eyes, having lost all strength, looking exactly like a broken doll.
Watching her friend so thoroughly defiled, Moeha didn't feel disgusted at all. Instead, her heart hammered against her ribs. So cute! Messy Kei-chan is so adorable!
After a few deep breaths to calm her racing heart, Moeha looked at Rin, who was sitting casually nearby.
"Big Brother... what on earth happened?"
Moeha had a camera, but she only dared to check it briefly during bathroom breaks at school.
She didn't even dare to watch for long!
If she got too excited at school, it would be a disaster. A single break wasn't even long enough to finish herself off in a stall.
And the more she restrained herself, the more explosive the excitement was when she finally saw the result!
Moeha felt her own panties were already soaked through.
Just looking at Kei's state and smelling the heavy, pungent musk in the air brought her to the edge.
"Well... Kei wanted to manage our desires for the sake of our health. I agreed to notify her every time we do it." Rin suppressed a laugh. "But if she's going to manage me, she had to test my limit. Well... Kei wanted to find my limit, and this happened."
Rin looked at the dazed girl on the bed.
"We started with her mouth. When her jaw got sore, we used her hands. When her hands got tired, we used her chest. When her chest got sore, we used her armpits. When those were coated, we used her hair..."
From head to toe, front to back, every part of her that could be used to process his lust was covered. At first, Kei had been keeping count of his loads, but eventually, her brain turned to mush and she could barely maintain consciousness.
"Mmph!!!!"
Hearing Rin's description, Moeha collapsed to the floor, clutching her lower abdomen. Just the thought of it sent her over the edge.
Rin stepped forward and scooped up the trembling Moeha.
Moeha was still a virgin. If he'd already eaten Kei, there was no way he was letting Moeha escape today.
