My Girlfriend's Secret Chapter 121: The Sisters Awaken Their Fetish

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 Cara 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 cara 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 Cara System, the Cross-Section System could only be activated when the Cara System was on, and it could only view the people within the Cara System’s range. She could switch views by ntally calling out a na.

For example... gumi!

The screen now displayed a cross-section of gumi’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 gumi’s cross-section... Mhm, small and cute too.

The sa was true for Ami and Maki. As for Nanami and Mashiro... so 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 ti, it’s pushed almost to the end. The door is knocked open a little bit each ti. 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 sothing 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 requirent, 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 Cara 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 abdon.

"I didn’t have ti 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 developnt... 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 , I... I need to keep an eye on you..." Hinata’s voice beca 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 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?"

"Co with ."

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 your purity, we’ve only just t, right? Can you tell 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 , you would beco normal again, and you chose 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 , right?"

The stunned Saya nodded. Now she admired Rin Ito even more. He’s worthy of being the man my sister chose!

"Co with ." 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, gumi eagerly rushed over to him.

"It should be our turn now, right?"

"Get lost, get lost..." Rin Ito waved his hand. "Next ti."

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 ho 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 ho... Mhm, mhm, mhm, it’s not just Ami; gumi is here too. Do you want to talk to them?"

Ami: "Auntie Hirose... yes, it’s Ami. Maki and gumi 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 gumi’s house to play, and then handed the phone to gumi and Maki to cover for her.

Finally, gumi did the sa, though gumi’s mother didn’t ask to speak to Ami and Maki. For the socially active gumi, spending the night at a friend’s house was common.

But... today, they weren’t at a friend’s house; they were at soone else’s boyfriend’s house, having a party. For gumi, it didn’t matter if it wasn’t her turn tonight; they wouldn’t check her hyn 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 co out now."

Hearing Rin Ito, Saya and Hinata exited their rooms almost simultaneously. The mont 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!
