The Cross-Section System... It really is a cross-section like the panels in manga!
After activating the Cross-Section System, a small screen appeared next to the main Camera System screen. As for the content on the screen... it was just like certain panels in those small comics.
Kaede's lips twitched... Watching the camera isn't enough; now I have to watch cross-sections too!?
Though complaining inwardly, Kaede still began to study the Cross-Section System. As a DLC for the Camera System, the Cross-Section System could only be activated when the Camera System was on, and it could only view the people within the Camera System's range. She could switch views by mentally calling out a name.
For example... Megumi!
The screen now displayed a cross-section of Megumi's body, though not a full cross-section, but primarily a cross-section of the little baby's room inside her body. Just like the panels in a doujinshi, Kaede could now see Megumi's cross-section... Mhm, small and cute too.
The same was true for Ami and Maki. As for Nanami and Mashiro... some residue still lingered inside their bodies from last night.
And Hinata... Holy moly, she's completely filled up!
She was so full that it was overflowing. The little chamber, at its limit, occasionally leaked a bit as Hinata moved. The most stimulating one, however, was Saya, who was currently in the act.
Whoa... She's stretched so wide.
Every thrust hits the deepest part... Hinata is pressing the shoulders really hard. Every time, it's pushed almost to the end. The door is knocked open a little bit each time. Doesn't that hurt?
No, no, no... Doesn't Hinata love Saya? Why is she pressing the shoulders so hard?
But honestly, this Cross-Section System is something else. It's pretty stimulating.
Watching the scene in the Cross-Section System, Kaede unconsciously imagined what it would feel like if it were her. Even without the Quest requirement, Kaede was beginning to feel the urge. Watching the Cross-Section System, Kaede's fingertips kneaded in rhythm with Rin Ito.
It's... it's coming!!!!
Even though she was still a virgin, seeing the slightly enlarged beast in the Cross-Section System told Kaede the climax was imminent!
In the Camera System, Rin Ito, who had been lying still, placed his hand on Saya's waist, coordinating with Hinata, who was pressing on Saya's shoulders. With the final thrust, Rin Ito firmly pressed down on Saya's waist.
"Eee!?!?!?!"
Under Kaede's gaze, although the city's sturdy gates were not completely breached, the beast, having drilled in half its head, was enough to unleash a white torrent, destroying everything inside the city. Subsequently, the breached gate allowed billions of invaders to occupy the small chamber.
Hinata helped Saya from Rin Ito's body to a nearby sofa, her eyes fixed on Saya's lower region, which couldn't completely close and was twitching in spasms.
While Saya was stunned, Rin Ito pulled Hinata towards the staircase, leaving a trail of drips behind her due to her slightly bulging abdomen.
"I didn't have time to ask earlier, but what is going on with you and your sister?"
Rin Ito asked curiously. Although he had a general idea from the System Daughter, Rin Ito didn't have mind-reading abilities and didn't know the specifics. Even though the System Daughter said they had a cuckoldry fetish, it was still under development... Why are they doing this mutually self-sacrificing thing when they clearly love each other?
"We... we were helping Kaede win her man back." Hinata nervously averted her gaze. "S-Since Kaede lent you to me, I... I need to keep an eye on you..." Hinata's voice became softer under Rin Ito's scrutiny.
"I'm sorry!!!" Hinata bowed deeply, but seeing the beast slowly reawakening in front of her, Hinata quickly looked up and said sheepishly, "It's just... I love Sister Saya... not in a sisterly way, but... like a man loves a woman. That's... not normal. So... I thought... if... if my purity was taken... that would definitely make me normal again."
"...." Unsurprisingly, the heroine of the underground world has a bizarre line of reasoning. "And have you returned to normal now?"
"No." Hinata bit her lower lip. "No... and... I feel even stranger now. I... I watched Sister Saya being fucked until her eyes rolled back, and I... I... I even felt incredibly excited. Why...? Do you know why I would have such a thought?"
"Come with me."
Rin Ito led Hinata to Mashiro's room and, under Hinata's curious gaze, pulled out a few doujinshi from under Mashiro's bed and handed them to Hinata. Hinata's eyes widened as she flipped through the few pages.
Ignoring Hinata, Rin Ito went downstairs.
Saya's eyes were still slightly dazed. Rin Ito picked up Saya, and like Hinata, Saya left a trail of drips.
"Uh... Saya Sakuramiya, although I'm happy you gave me your purity, we've only just met, right? Can you tell me why?"
Although he asked, Rin Ito had a pretty good idea, probably for similar reasons to Hinata.
"We... we were helping Hinata win her man back." Saya nervously averted her gaze. "S-Since Hinata loves you, as Hinata's sister... I... I wanted to help Hinata."
Rin Ito stared intently at Saya, just as he had with Hinata. Under his gaze, Saya slowly began to speak.
"I'm sorry... I... I love Hinata, not in a sisterly way, but... like a man loves a woman. So..."
Before Saya could finish, Rin Ito interrupted her. "So you thought that feeling was abnormal, and if you were taken by a man and then watched Hinata be taken by me, you would become normal again, and you chose me because it helped Hinata win her man, killing two birds with one stone, right?"
"Eh... Yes."
A hint of admiration appeared in Saya's eyes. Amazing! He guessed that too?
"But now you're also confused about why you got aroused watching Hinata be taken by me, right?"
The stunned Saya nodded. Now she admired Rin Ito even more. He's worthy of being the man my sister chose!
"Come with me." Rin Ito sighed and led Saya to his own room. He pulled out a few NTR doujinshi from his reference materials and handed them to her.
"You read these first."
With that, Rin Ito left Saya and Hinata and returned to the living room. Seeing Rin Ito, Megumi eagerly rushed over to him.
"It should be our turn now, right?"
"Get lost, get lost..." Rin Ito waved his hand. "Next time."
Although Rin Ito wanted to take them, he still hadn't fully resolved the situation with Saya and Hinata, so they'd have to wait... Tonight's mission was to thoroughly develop Hinata and Saya's cuckoldry fetish!
"Do you want to stay or go home first?"
"Stay!" the three girls said in unison. They exchanged glances, then all picked up their phones.
Maki: "Hello... Mom, yes... I'm staying at Ami's house tonight, so I won't be coming home... Mhm, mhm, mhm, it's not just Ami; Megumi is here too. Do you want to talk to them?"
Ami: "Auntie Hirose... yes, it's Ami. Maki and Megumi are playing at my house today... Mhm, okay, we'll be careful and won't stay up too late, mhm, mhm, mhm."
After Maki hung up, it was Ami's turn. Ami also called her mother, saying she was going to Megumi's house to play, and then handed the phone to Megumi and Maki to cover for her.
Finally, Megumi did the same, though Megumi's mother didn't ask to speak to Ami and Maki. For the socially active Megumi, spending the night at a friend's house was common.
But... today, they weren't at a friend's house; they were at someone else's boyfriend's house, having a party. For Megumi, it didn't matter if it wasn't her turn tonight; they wouldn't check her hymen when she bragged about it! As for Ami... a party was much more stimulating than a doujinshi. Maki wasn't that interested in the party itself, but she knew Ami would definitely stay, so if Ami stayed, she would too.
Rin Ito didn't mind if they stayed to watch. They could also help him out as assistants.
After sorting things out with the three girls, Rin Ito estimated that the two sisters had finished reading the NTR doujinshi, so he returned upstairs. In the hallway, Rin Ito called out to them, "You can come out now."
Hearing Rin Ito, Saya and Hinata exited their rooms almost simultaneously. The moment they stepped into the hallway, they noticed each other. Although they didn't speak, their sisterly bond allowed them to instantly understand the situation: My sister (or I) also has a cuckoldry fetish!
