I Realized I Was the Cheating Bastard in a Hentai Manga only after I Had Already Stolen the Heroine - 41

Chapter 41: Lies and Truth

ーーーーーーーーーーーーーーーーーーーー

~Rui Yamada’s POV~

“I’m home…”

Even when I returned home, no one responded. Dad and Mom had said they’d be out for a few days, so the house was eerily quiet. Up until now, when I came home, Mom, Kou-nii, and Kyou-nee would greet me with an “Welcome back.”

Since I was in the brass band club at school, the two of them, who weren’t in any clubs, were often home before me. It had been a lively daily life. A fun daily life. When did it start? When did it become so lonely?

One day, Kou-nii told me he and Kyou-nee had started dating. I was thrilled— if they got married, I could become real sisters with my beloved Kyou-nee. So I congratulated them. Kou-nii puffed out his chest with a smug look.

Some time later, I heard Kou-nii’s excited voice coming from his room at night. Kyou-nee’s shoes were at the entrance, so I got a fluttery feeling realizing they’d entered an adult relationship.

Imagining that scene, I touched myself alone. I thought those days would continue forever. But after a while, Kyou-nee stopped coming to our house as often. She’d come in the morning to wake Kou-nii up, but she was gone more often at night.

Mom seemed concerned about it too, and when she asked Kou-nii, he said Kyou-nee had been busy lately. He said they were still flirting as usual at school or after school. Kyou-nee’s grades were excellent, and she couldn’t say no when asked for help, so she must be busy too. 

Then, that day came. Kou-nii stopped leaving his room. It was so sudden, I couldn’t process it. When I asked Mom, she said Kou-nii and our whole family had done terrible things to Kyou-nee, and she couldn’t take it anymore. I didn’t understand.

I had never said anything mean to Kyou-nee. Kou-nii kept saying they were so in love. When summer vacation started, Kou-nii gradually came out of his room. But he wasn’t the confident Kou-nii from before, he’d become an irritable, scary person.

Kyou-nee used to take him for haircuts and help him keep up his appearance, but without Kyou-nee in the picture, he looked awful. I was scared of this Kou-nii, but I couldn’t believe Kyou-nee was gone, so I asked him.

“We didn’t do anything bad to Kyou-nee, right? That’s a lie, isn’t it?”

Kou-nii, with bloodshot eyes, laughed and grabbed my shoulders, telling me the truth. Kyou-nee was being deceived by a bad man, he said. She was being blackmailed and forced to break up with him. That guy was a crazy, dangerous jerk, and Kou-nii couldn’t take Kyou-nee back yet. He told me to stay away from him because he’d resort to violence instantly.

I knew it. Someone as kind as Kyou-nee wouldn’t break up with Kou-nii for no reason. Dad and Mom must have lied to keep me out of danger. Kou-nii said “not yet,” so I thought our old days would come back someday, and that eased my loneliness a bit.

Summer vacation ended, and school started. Kou-nii still didn’t seem ready to go back to school. I felt anxious, wondering when those days would return, but there was nothing I could do, so I kept enduring.

And then, today. By chance, I ran into them. Even from a distance, I knew it was Kyou-nee. There was an older guy with her. I was so lonely, but seeing them look so happy made me jealous, and in a fit of anger, I threw a rock…

As soon as I threw it, I saw it flying toward Kyou-nee. The guy shielded her, and when I saw the rock hit him and blood come out, my mind went blank.

Kyou-nee was completely distraught, crying. And then she yelled at me. I’d never seen Kyou-nee so upset and crying, or so angry. I didn’t understand.

Wasn’t she forced to be with him…? I overheard Kyou-nee say she was going to the drugstore. As she passed by me, her face wasn’t just angry—it felt like she hated me. It was terrifying…

The guy spoke to me. Kou-nii had said he’d resort to violence instantly, so I was scared he might hit me. But despite his appearance, he smiled at me with such a kind face. For some reason, I instantly believed him when he said he wasn’t mad at me.

We moved to a park, and he asked me why I did it. He looked like he had no idea what was going on, which made me angry again… But he listened to me seriously. Kyou-nee came back. The guy told me to apologize to her, so I tried, but Kyou-nee wouldn’t listen… No, she didn’t even acknowledge my existence…

Kyou-nee abandoned me…

Then the guy persuaded Kyou-nee. She finally looked at me and apologized to me. Thanks to him, I was able to apologize to her too. I explained to Kyou-nee what I’d told the guy.

…She said it was all a lie… I didn’t want to believe it. Everything Kou-nii said, a lie…? But… The guy was so kind. Kyou-nee seemed to really love him. The way they looked at each other… It seemed they were genuinely happy. 

Come to think of it, what kind of face did Kyou-nee have when she was with Kou-nii…? Her face, despite all the time we spent together… I couldn’t remember it. Still clinging to my disbelief, I returned home.

At home, I was sitting dazed in the dining room when I heard the front door open. Dad and Mom weren’t supposed to be back yet, so I was puzzled. Then Kou-nii walked in. Kou-nii were away? How rare.

“Welcome back. Were you out somewhere?”

Kou-nii had a vacant expression…He didn’t even respond to me, but I wanted to know the truth. I steeled myself and spoke to Kou-nii.

“…Hey, Kou-nii. Kyou-nee’s really being blackmailed, right…?”

Kou-nii looked at me. His wide, staring eyes were scary…

“What are you talking about? Of course she is! That guy’s the worst kind of jerk. I went to school today, and he yelled at me!”

Hey, Kou-nii. Why are you talking with that creepy grin…? Kyou-nee was taken from you, right…? Why aren’t you being genuine to me…? The guy and Kyou-nee talked to me so genuinely…

“That’s right! Hey, look at this! That guy’s cheating with another woman while he’s with Kyouko!” Kou-nii showed me a cracked smartphone. On it was an image of the guy having sex with an unfamiliar woman. The guy had a playful expression, but his eyes were that same kind look.

“…You went to school to show that…?”

“Y-Yeah! That’s right! I wanted Kyouko and everyone to know his true colors!”

If she’s being blackmailed, what’s the point of showing her his true colors…?

“…What did Kyou-nee say?”

“Get this! Kyouko said she’s disappointed in him too! The whole class was condemning him! And then he got mad and yelled at me out of spite! He’s the worst, right!?”

…Ah. …I get it now. The liar is Kou-nii. Everything Kou-nii says is nonsense. Having that image means he really did go to school and show it to Kyou-nee. So, does that mean Kyou-nee knows about the person in the image? She knows, and she’s still with the guy. She knows, and she loves him, doesn’t she?

Kou-nii was still talking, spitting everywhere. Looking at him made me feel empty…

“Hey, Kou-nii… Let’s stop this…?”

“…Huh?”

“It’s all a lie, isn’t it…? I met Kyou-nee and the guy today… Kyou-nee looked so happy… The guy was a kind person too…”

“…What’s that supposed to mean…? I told you to stay away from him…”

“She knows about the person in that image, right? And she’s still with him…”

“N-No… How do you…”

“Mom said… We did terrible things to Kyou-nee, and she couldn’t take it anymore. Hey, Kou-nii… Let’s stop getting involved with Kyou-nee. Rui will stay out of it too. Let’s let Kyou-nee be happy…”

“…Tch…”

Kou-nii was muttering something, head down.

“…Kou-nii?”

“I said shut up!”

“Eek!”

Kou-nii yelled at me!

“Why are you siding with him too?! You’re my sister, aren’t you?! Take my side!!”

“I-It hurts! It hurts, Kou-nii!”

Kou-nii grabbed my shoulders. His fingers dug in, it hurt!

“I get it now…! He fucked you, didn’t he?! That’s why you’re on his side!”

Bang!

“…! Ow…!”

Kou-nii slammed me to the floor. Pain shot through my body. Kou-nii looked down at me with cold eyes. His gaze moved to my lower body…?

“!!!”

Flip!

The impact of being thrown flipped my uniform skirt. I quickly fixed it, but Kou-nii’s gaze had turned lecherous.

“Come to think of it… You let a guy like that fuck you, huh? What a slut…”

Kou-nii crept closer…

Scary… Scary, scary, scary!

“If he’s got fuckbuddies, I should get to fuck whoever I want too!!”

Kou-nii straddled me!

“S-Stop!! I-It hurts!! It hurts, Kou-nii!!”

Kou-nii grabbed my chest with all his strength!

It hurts! Scary! Scary!

Kou-nii tore my uniform blouse, exposing my bra. Kou-nii then pulled down his sweatpants and  brought his hardened cock close to my face.

“Come on, suck it! Suck my dick!”

It was smelly… 

Gross… Gross, gross, gross, gross, gross!!

I turned my face away from it with all my might.

“I said suck it!”

Slap!

Kou-nii slapped my cheek.

It hurts, it hurts, it hurts, it hurts!

He grabbed my face and forced his cock toward my mouth.

“Sob… N-No… Lick… Ugh… Gag…”

When I licked his cock, the smell and taste made my body recoil, and I gagged…

“Tch! You can’t even do it like Kyouko, huh? Fine, then this!”

Kou-nii moved to my lower body and… He tried to pull off my underwear!

“No!! Stop!!!”

“Shut up! Don’t resist!!”

Gross, gross, gross, gross, gross!!!

Instinctively, I reached for the bag lying nearby and then—

“Agh!!!”

I threw the bag at Kou-nii. While he stumbled, I escaped!

“Wait!! Don’t run!!”

Kou-nii couldn’t chase me right away because his pants were down. Catching my chance, I bolted out the front door.
