At lunch, Hanna sat down with her brother's friends.

”How is Kyle doing?” Rick, the one with freckles asked.

”He just needs time to recover. He mostly sustained soft tissue damage from his accident. The doctor said it was a miracle he came out as unharmed as he did.”

There was awkward silence without Kyle.

She wanted to casually start talking about ”Vinegar,” the off-brand Bleach anime all the kids were watching these days, but she had never heard them talk about it so she figured that they might not be into it. Not all smart nerds loved anime and not all anime lovers were smart nerds.

But she just quietly finished her meal and left to go use the restroom before class started. Then she planned to study a bit before the test in her history class. The one she really had the most trouble with.

And just as she finished doing what she needed to in the bathroom stall she noticed something small glinting in the ceiling...

Oh no! She knew what this was. It was a pinhole camera!

She hoped it didn’t have pictures of her on it. And that it didn’t update to the cloud. Shit. She had to grab it and figure out who did this. She also needed to permanently delete all pictures the sicko had. But she wasn’t that great with computers. If she had been, then she wouldn’t have gotten stuck as a cashier for the past dozen years.

Maybe Kyle had hidden hacker skills? She hope so, because she refused to trust anyone else in this stupid Hentai World.

She stepped onto the toilet seat the briefly steadied herself against the wall when the door burst open. Two sets of footsteps hurried in. The click of someone locking the door echoed in the small room.

”You can't just tie me up in bed like that!” That voice was definitely Paul Gibson again. “I barely escaped to make it to class on time!”

“Dana—“

“What about her?!”

“You were talking to her yesterday!”

“Is that a crime?!”

“It is if you plan to cheat on me with her.”

There was a long pause. “Kelli. I’m not going to do anything with Dana. I don’t even like her.”

“The way she looks at you, she’s planning to come on to you. I just know it. And I can’t stand thinking that you might let her... and—“ she hiccuped.

Yandere adopted sister alert!

“Kelli! I would never!”

Never? Really?! This was Hentai World. And if it was anything like actual hentai, nobody could be assured of anyone’s fidelity here. That wasn’t to say that there weren’t loyal people who wouldn’t betray each other, it was just... NTR was a trope that existed.

She was about to speak up and let them know that she was here and not to reveal anything else when Paul said, “Then I’ll just have to show you how much you mean to me.”

The sound of clothing ripping ran through the bathroom, and that was when she knew she was in trouble. She still needed to study for that test, but she absolutely couldn’t interrupt them.

It wasn’t because she didn’t have the cajones to interrupt public sex, but because one of the partcitipants was a damn Yandere. And one did not upset Yanderes unless one was the object of their affection. Because Yanderes did not give a shit about anyone else. They were the type of people who would literally kill the world as long as their beloved stayed by their side forever.

In a way it was kind of creepily sweet. And maybe a little hot too. They made for fantastic love interests… in stories. And, in those stories, they brought lots of conflict wherever they went. However, in real life—or what Hanna now accepted as her real life—they were the type of people that one ran from. Especially if their object of affection paid any attention to them.

But this meant that Hanna absolutely could not interrupt the yandere having sexy time with her object of affection. She had to stay in her position and not make a sound.

But she did have her cellphone tucked in her bra. It wasn’t exactly sanitary to use it before washing her hands but she could sanitize it several times after. It was waterproof. She’d checked.

And using her phone to study was better than crouching on a toilet seat and listening to two cousins going at it.

But, before she did that... Maybe they weren’t actually doing what she suspected? It wouldn’t hurt to take a little peak, right? She was stuck here because of these two, afterall.

Slowly, she crept her hands up the wall and twisted so she could look above the stall. Sure enough, ripped pink panties had been thrown onto the tile floor haphazardly. The adopted sister’s skirt—the one from her school uniform—was thrown up and she clutched at the sink with one hand and used the other to stifle her moans of happiness. The brother’s pants were halfway down his thighs and he thrust back and forth behind her with no finesse whatsoever. Fortunately, the brother’s shirt hid his ass.

After about a minute of that finessless thrusting, the hentai main character lifted both of his adopted sister’s legs up in an impressive feat of holding her up while doing her. It took some actual strength to pull that off! Who knew Paul had it in him?

The two cousin's eyes met in the mirror.

“This is how much you mean to me!”

That didn’t make a whole lot of sense to Hanna, but maybe it did to the pair?

Technically, because they kept their clothes on, she couldn’t see anything even though she knew what they were doing. And since watching this was boring, she decided to forget it and study like she was supposed to.

She hunkered down into the most comfortable crouch she could, pulled out her phone, switched that shit to airplane mode with the sound on silence, and started to type into the ‘Xoogle’ search engine.

She read more on the topic of the next test that went over WWII during the first year. History that was similar but different and weird.

The moans from outside and the sound of flesh hitting flesh became increasingly distracting.

“Do you like that?”

Hanna grimaced at the interruption.

“Un! You feel so good inside me. Like you belong there.”

“That’s right.”

‘... by invading neutral HHH and BBB Countries. GGG also attacked northern FFF...’

“How can I think of anyone else when we’re this good together?”

“P-Promise! Promise that you’ll only make love... to… your sister!”

Seriously? Why? Hana started reading louder, ‘...evacuation by sea was organised under the direction of BBB Country’s Admiral B. Ramsay. Over the next nine days, warships of the—‘

“No!”

Oh, shit! The girl said no! Did Hanna need to step in after all?

“Brother! I— I can’t, anymore!”

Wait? Did this girl just say no without meaning it?! It was this kinda bullshit— well, maybe they had a safe word.

“You can. Only you can take all of me like this.”

She started reading harder.

“No! It’s too much. I’m going to—“

‘—BBB and FFF navies together with—‘

“Me too! I’m coming! I’m going to come inside you!”

‘—CIVILIAN CRAFT...’

Loud groans of pleasure echoed through the room.

Wow. That was surprisingly fast! Back in her original world, sometimes an hour—

“Brother!”

“Kelli!”

The pair sounded like they might go again when someone knocked on the door. The two rummaged around, probably tidying up, then left.

Someone quickly ran into the stall next to her. Hanna lifted the ceiling tile.

“Eeep!” The girl in the next stall said.

Hanna ignored her and reached for the small and black camera. Then she wiggled it out of the ceiling square and shoved it into her skirt's pocket. When she went to sanitize her phone and wash her hands (then sanitize her phone again) she noticed that some of the ties were wet.

They’d been dry when she walked in…

Eeeeeeeew!!! Couldn’t these assholes have cleaned that up before they left?
