Izumi Sagiri... so amazing! Watching Sagiri 'drink' so much, the girls had only one thought at this moment.
"Do... do you feel anything? Does it hurt?" Maki asked with some unease, making the exit an entrance... there was always a feeling. "Ugh... my stomach feels full." Sagiri gently rubbed her stomach. Although Sagiri felt she had 'drunk' a lot, it was still far less than what was depicted in doujinshi. In reality, it was impossible to become as big as if pregnant, like in doujinshi... that would be fatal. Sagiri's lower abdomen remained flat, showing no signs of being full, but it wasn't long before Sagiri started to feel it...
"No... no, I have to go to the bathroom!!!!" As Sagiri clamped her legs and took a step, Ito Rin grabbed her wrist. Then, Ito Rin took out a small stopper from his backpack. "...?" Sagiri, who had read many doujinshi, naturally knew what that meant. After being filled, it was to be plugged, similar to the edge control training from before.
"It's okay if you can't hold it, I'll just help you block it... Since you're friends, you should go together, right? In school, do boys and girls always go to the bathroom together during breaks?" "That's right, that's right." Megumi Kamino, Ami, and Maki frequently echoed, "In school, everyone goes to the bathroom together." Sagiri glared fiercely at the three of them... they would get theirs later! Sagiri cautiously stuck out her butt. "Ah..." The touch of the cold metal made Sagiri let out a small gasp. Sagiri couldn't relax; instead, she had to strain hard to prevent herself from being exposed in front of everyone. However, the strength of Sagiri's butt was definitely no match for Ito Rin's hand. After passing the widest point, it was as if with a 'pop', Sagiri swallowed the stopper. Aside from feeling a bit like needing to go to the bathroom, there wasn't much discomfort. Sagiri snatched the syringe from Ito Rin's hand. "I'll feed them!"
...
"Ugh!" "Gulp!" "Eek!" Megumi Kamino, Ami, and Maki all lay prostrate on the ground, their three upturned butts lined up side by side, their muscles tensed due to nervousness. From Ito Rin's perspective, not only could he see all the girls' hidden parts, but in contrast to their slender waists, their slightly meager butts also became perky. Ito Rin was already incredibly excited looking at the three lined up, but now was not the time to 'eat' them.
Ito Rin even mischievously filled the water to the brim, estimated to be about one-third more than Sagiri had 'drunk'. Sagiri was still rummaging through her backpack, looking for stoppers for Ito Rin to plug their 'leaks'. Each time he finished injecting warm water into them, Ito Rin took a stopper from Sagiri's hand and plugged the impending 'leaks' for the three girls, who, with flushed faces, covered their stomachs with one hand and their butts with the other.
"Ca... can we now?" "No~ Only one person can go to the bathroom." "Big Brother?" "What exactly do you want, you pervert!?" Maki, her face flushed with shame and anger, glared at Ito Rin and pouted. This feeling was truly uncomfortable. With the 'leak' plugged, even if they relaxed their muscles, they couldn't release it.
Ito Rin looked at Sagiri with a half-smile, "They bullied you so much just now, don't you want revenge?" Upon hearing Ito Rin's words, Sagiri's eyes lit up. Just like keeping a secret... the best way to keep a secret is to make the other party part of the secret. Since she had opened her eyes and exposed her most shameful appearance in front of them, it was only fair that they too should expose their shameful appearance... From Sagiri's years of understanding Ito Rin, they were in for it!
Ito Rin stifled a laugh and took out two small chains from his backpack. Everyone looked puzzled, except for Ami, who was wide-eyed with shock... "Huh? Isn't this the chain that connects to the collar? Is Big Brother going to make us cosplay as catgirls in this situation?" Megumi Kamino looked puzzled. When Ito Rin first arrived, she had seen his backpack, but hadn't paid much attention. After all, it was for catgirls. When they went to Comiket this morning, they also saw catgirl cosplays, with chains connected to red leather collars. But now it seemed... this chain seemed to have another purpose?
"Uncle... this chain couldn't be..." Unlike the puzzled Megumi Kamino, Ami, who often read doujinshi, seemed to understand something. Ito Rin gently patted Ami and Maki's butts. The knowledgeable Ami immediately stuck out her butt. Maki, looking bewildered, also imitated Ami and stuck out her butt. Then... Ito Rin used the chains to connect the stoppers on their bodies, and then Sagiri and Megumi Kamino.
"Ahem..." Ito Rin cleared his throat, "Only one person can go to the bathroom, so... let's start the tug-of-war." "Pervert... ah!" Before Maki could finish her sentence, Ami gently pulled the chain behind her butt, causing Maki on the other end of the chain to shriek. Sagiri also tugged the chain, making Megumi Kamino tightly cover her butt. "Ami, Sagiri, that's cheating. You can't use your hands in this tug-of-war." Ito Rin cleared his throat and said seriously.
"The loser loses everything, and the winner gets to sit on the golden toilet!" Then Ito Rin began to explain the rules to them. "The rules are simple: you divide into two groups, pair up, lie down, and crawl forward. The first to let go loses, and then the winners of each side will have a showdown to decide who gets to use the toilet." Gulp... Maki swallowed her saliva. "Then... what about the losers?" "Hehehe..." Ito Rin let out a villainous, evil laugh, "The losers? The losers don't need to go to the bathroom the moment they lose."
Maki was only interested in cute catgirls, Megumi Kamino was interested in naughty things, and they were both uninterested in the tug-of-war game. Only Sagiri, who wanted revenge, and Ami, who wanted to experience doujinshi-like play in reality, were interested. But now the chains were already attached. If they said they wouldn't participate, Ito Rin might just pull the chain the next second.
...
While Ito Rin was explaining the rules to them, Aoi was also watching everything in the bathroom through the Camera System... Would he make himself and Rin play such a tug-of-war game in the future? And then Mashiro and Kikai too? And Hinata and Saya. Aoi subconsciously swallowed his saliva. He definitely wouldn't be Rin's opponent... he would definitely 'spray' in front of Rin then. Although it could be cleaned thoroughly by the system, leaving no smell or dirt, still... the thought of that scene made Aoi's brain tremble. Was there any enhancement to make specific muscles strong and powerful? Aoi quickly scrolled through the System Mall. In his own 'cuckold' mall, there were enhancements for becoming sensitive and becoming a 'small fry', but for becoming strong, it was only in their 'female yellow hair' System Mall.
And as Aoi scrolled through the System Mall, on the other side of the Camera System, the girls were already ready, and the tug-of-war game officially began.
