Kotonoha woke up in Makoto's arms.

"Morning, beautiful." He gave her a kiss.

She eagerly kissed him back. While her hands roamed his body, her tongue pushed past his lips.

Makoto gently pushed her down.

"You were dreaming about it again," he said.

"About what?" Kotonoha tried to kiss him again, but he held her down.

"You know what," Makoto said. "You were mumbling in your sleep."

"That… that's just because I… I saw something."

"You saw what?"

"The… hold on, I'll show you."

Kotonoha untangled herself from his body and threw on a bathrobe. She went downstairs and knelt before the couch. She found the stack of pictures below it and took them back up. Makoto was waiting for her.

She got on the couch.

"I discovered my mom had an affair," Kotonoha explained. "And she was doing… that with her lover." She handed him the pictures.

"Oh. Wait, who took this picture?"

"I have no idea," she admitted.

"Where did you find this?"

"In the album of my child pictures."

"That's odd." Makoto moved to the next photo. "So that's why you…"

His eyes widened.

"Makoto-kun?"

"That… that man." There was a look of horror on his face.

"You know him?"

"You bet I do. That's my dad."

"What?"

"Yeah, that's him. He's younger, but it's definitely him. No doubt about it."

"So your dad had an affair with my mom?" she asked.

"Apparently. Not surprising, he hit on everything with a skirt."

"Hold on a second," Kotonoha said. "Does that mean we… we're…"

That couldn't be true.

"No, no. You can't get pregnant from doing this." He held up the picture.

"Keep looking," Kotonoha said.

He went through the pictures. "Oh. Yeah, you can get pregnant from that. I don't see any condoms."

"Oh no. No no no."

"Okay, let's not jump to conclusions here. We don't know for sure when your mom had this affair."

"But it's possible."

"I guess," Makoto admitted. "We can't know for sure. Unless we do a DNA test of course."

Wait a second. She couldn't do this. She did want to know, and she was scared, but… but if this was true then…

"Let's… let's just pretend we never saw this," she suggested.

"Woah, hold on. You could be my half-sister. Kokoro-chan could be my little sister. If this is true then…"

"No. We can't break up over something this stupid."

"Stupid? Kotonoha, this is incest."

"And what would you call you fooling around with my little sister?" she shot back.

"Well that's not… I… that's something completely different."

"Yeah, it's illegal. You can't just… have sex with her."

"I didn't have sex with her," he pointed out.

"You… you fooled around with her."

"That's very different from incest."

"Incest is not illegal here, Makoto-kun. And we're only half-siblings. Maybe half-siblings."

"In any case, I want to know."

"And I don't. I want things to stay the same. Makoto-kun, please-"

"It's never gonna be the same until I know," he said. "We can't… we can't do it if I don't know if you're my sister or not."

"Half-sister."

"Whatever, I'm gonna find out. You coming or not?"

He got out of bed.

"We're doing a DNA test?" she asked.

"No, I'm going to see my dad. Are you coming?"

"Yeah, sure."

They both got dressed and went downstairs. Kokoro was still sleeping so they wrote her a note so she wouldn't worry.

After a quick breakfast, they left. Makoto drove to the car to his dad's house.

They spend the trip in icy silence. Only when they arrived did she speak.

"I didn't imagine the first time meeting your dad like this."

"Me neither," Makoto admitted. "Come on."

They got out and walked up to the door. His house was huge. Almost as large as Kotonoha's old house.

On the doorbell it said:

"Itaru and Itaru?"

"Tomaru," he corrected her. "Written the same way. Sawagoe Tomaru and Itou Itaru."

"Oh."

"Let's do this."

Makoto took a deep breath and rang the doorbell.

Nothing happened.

He rang it again. Still nothing.

"Maybe he's not home?" Kotonoha suggested.

"No, he's home." Makoto balled his fist and knocked hard. "Dad! I know you're in there."

They heard stumbling and then the door finally opened. A bewildered man stood inside the doorway. He was much older, but it was clear it was the guy from the picture. His brown hair was much longer and he had a goatee now. But his intense brown eyes were the same. As was the permanent smile that played around his lips.

He was dressed in a bathrobe that was loosely tied. Beneath it, she saw he was in excellent shape. His muscles were clearly visible.

"Makoto," he said. "What are you doing here? And who's the beauty?"

"We gotta talk," Makoto said.

Without waiting for a reply, Makoto stepped inside. While he could clearly stop him with one hand, Makoto's father only protested weakly.

"Now is not really a good-"

"Tomaru-senpai?" a female voice said.

A girl walked downstairs. She was blonde and rather busty. It was easy to see because she didn't wear any clothes. Just the covers of his bed loosely wrapped around her body like a gown. She stopped halfway the stairs when she spotted them. "Oh."

"Just a friend of mine with a problem," Tomaru said. "I'll be right back."

"Okay." She smiled. "We'll be waiting for you."

With a wink, she left.

Makoto raised an eyebrow. "We?"

"Twins," Tomaru said. "Why are you here, Makoto? And who's the girl?"

"Oh you don't recognise her, do you?"

"Not really," Tomaru said slowly. "I didn't fuck her, that's for sure. I'd remember tits like that."

"Unbelievable."

Makoto walked to the living room.

"Hey wait," Tomaru protested.

Kotonoha had no choice but to follow them.

"I still don't get it," Tomaru said.

"Recognise this?" Makoto pulled out a picture.

"Oh. Yeah, that's Manami," Tomaru said. "Where did you get this?"

"Manami…" Kotonoha swallowed. "Manami was my mother."

"Oh. Wait, she's dead?"

"Not the issue now," Makoto said. "Talk."

"Hey look," Tomaru said. "She seduced me."

"Oh please," Makoto said. "You seduce anything with a skirt."

"Well not her. She's not my type. Rich, bitchy, nice tits, sure, but really not my type."

"What happened?" Makoto demanded.

"That's a long story."

"We've got time." Makoto sat down on the couch.

Tomaru's eyes darted to the door.

"As do you," Makoto added. "You're not going anywhere."

"Just give me one second to send them home, okay? I don't want to let them wait for something that's not gonna happen."

"Fine."

Tomaru left them.

Kotonoha sat down with Makoto. "You sure you want to hear this?"

"Yes. I have to know."

"And what if…"

"I don't know," he admitted.

"I'm not leaving you, Makoto-kun. Even if you are-"

"Kotonoha, this is a big deal. If this is true, we can't have kids."

"Oh please. A half-sister shares as much DNA as a double cousin. And cousin marriages are very common. Besides, do we forbid people with genetic diseases from having kids? No. If you're deaf or blind, you can have as many kids as you like even though there is a huge risk they will get it too. But for siblings we suddenly care about genetics?"

"Still-"

"Besides," Kotonoha said. "Do you really want kids?"

"I… I assume you will want them sometime in the future."

"Oh really? And you're gonna explain to those kids that mommy and aunt Kokoro both sleep in your bed?"

"We… we can talk about this later."

Kotonoha hid her smile. That was exactly what she had hoped for. Right now she had to convince him to stay with her, even if they were related. And if she did want kids later on, she could always try to convince him then. For now, saying she didn't want any might convince him to stay with her. She could think about this later.

Tomaru returned.

"Does anyone want a drink?" he asked.

"No thanks," Makoto said. "Start talking."

His dad sat down opposite of them.

Kotonoha reached out and took Makoto's hand.

It was gonna be alright, she told herself. No matter what happened.

"Okay, so Manami was a frequent customer in one of my beach bars," Tomaru said. "Radish. I'm sure you've heard about it."

"I know it," Makoto said. "Stop stalling."

"She was a rather annoying customer. One day, she asked me to fuck her."

"What?"

"You said stop stalling. So I'm skipping ahead. She asked to see the manager, came into my office, took out her tits, which were huge by the way, and asked me to take her. Right there."

"Which you did," Makoto said.

"No, of course not. You don't put your dick in crazy. Well, not unless you've trained her well of course."

"Uhm, what?"

Tomaru sighed. "Are you even my son? Listen, when a woman behaves like that, she obviously wants something. And you have to know for sure what that is. Maybe it's a good fuck. But it could also be trying to get me out for sexual harassment. So you look for clues."

"Like what?"

"Well the fact that she didn't have a condom with her was odd, considering she probably knew I slept around with half my staff."

"How do you know she didn't have one?" Kotonoha asked.

"There was nowhere to hide it on her dress."

"It could have been in her purse."

"Sure," he said sarcastically. "She jumped ahead and took her tits out, but then she was gonna dig around in her purse for a rubber. Very clever."

Kotonoha felt heat rise to her cheeks, both from anger and embarrassment.

The pictures spoke for themselves. He was not wearing a condom.

Maybe she just wanted to believe her mom would come good out of this?

"Back to the story," Makoto said.

"I told her I couldn't do that. She was confused because… well, it was me. And then she offered me money."

"She offered you money to fuck her?" Makoto asked.

"Yes. Weird, I know. So that made me more suspicious."

"And what did you do then?"

"Demand she empty her purse."

Makoto frowned, but he said nothing.

"She didn't want to," Tomaru said. "I was certain it was a trap, so I… well, we struggled a little, I managed to get her purse off and empty it. There was a letter inside. And it…"

He fell silent.

"Yes?" Makoto urged him.

"It was a letter from a doctor. A certain Katsura-san was infertile."

Both of them were stunned by that.

"And then she broke down and told me everything," Tomaru continued. "They had tried to get a kid, but it didn't work. So they had themselves examined. His letter came while she was home. And she didn't have the heart to tell him. So, she figured she'd get knocked up by someone else and pretend it was his child. And I seemed like someone who would be willing to fuck whatever and not ask questions. She got that wrong."

"And you… you knocked her up?" Makoto asked.

"Yeah, of course. She was a damsel in distress, I was happy to help. And that was it. A couple years later, she came back because she wanted a second kid, I helped her out again and that was the last time I saw her."

"Okay," Makoto said. "Sounds plausible."

"Wait," Kotonoha said. "That doesn't make any sense. Who took this picture? And if she just wanted to get pregnant than why were you doing something… something so dirty?"

"Hey, she wanted to have a little fun," Tomaru argued. "Not my fault."

"Talk," Makoto said, his eyes narrowing. "The whole truth. Or I'll be telling some truths to Itaru-chan."

"Fine," Tomaru said. "But you keep your woman under control, because she's not gonna like this."

"Kotonoha won't do anything," Makoto assured him.

She wanted to protest, but she couldn't find the words.

"Okay," Tomaru said. "So maybe I blackmailed her a little bit."

"What?" Kotonoha jumped up.

"Kotonoha, sit down," Makoto said.

"But-"

"Down," he said sternly.

She slowly sank back down.

"I want to know the whole truth first," Makoto said. He took her hand. "And then we'll decide what we'll do with him."

"Oh, are you sure?" Tomaru asked. "Cause I know some things about you that-"

"Don't change the subject," Makoto said. "Keep talking."

"I'm gonna get a drink first."

Tomaru left them.

"I'm gonna kill him," Kotonoha said.

"Let's not do anything impulsive," Makoto said. "We need to know everything first."

Kotonoha said nothing. But inside, her thoughts were swirling.

Tomaru returned. He sat down on the couch and calmly sipped his drink.

"Now where was I?"

"You-"

"Oh, right. The blackmail. So I quickly pieced together she didn't want her husband to know about his useless cock. Which is quite small too by the way." He paused for a reply that didn't come.

Kotonoha bit her tongue.

"So," Tomaru said. "I threatened to tell everything to her husband. She started begging, offering me money. I said I wasn't interested in money. I wanted her body. She was confused because she just offered it. And then I told her I wanted her my way. I was gonna help her get pregnant, but we were gonna have sex on my terms. When I wanted and how I wanted."

"Like this?" Makoto held up a picture.

"Obviously I took all of her virginities. Don't worry, I was gentle. Well, not too gentle of course. Wouldn't want her to forget her place. Trust me, the moment you fuck their ass hard for the first time, they really start understanding who owns them. She became much more obedient after that."

Kotonoha bit down harder on her tongue. She tasted blood. But at the same time, heat started to pool in her belly.

Understanding who owns them.

Fuck. Why was that so hot?

No, no. This was crazy. This monster was blackmailing her mom.

"And what about these pictures?" Makoto asked.

"Well initially I had some pictures on my phone. Just in case you know. If she decided she'd tell her husband about his little problem downstairs or he figured it out, my leverage was gone. So I took some pictures in case it was necessary."

"You didn't take these with a phone."

"No, I'm getting there. You see, I was right. She did tell her husband. Not just that he was infertile, but the whole thing. About how I pushed her to be my sex slave and she had to work really hard to get a load in her pussy. The whole thing. And then. You're not gonna believe this, but her husband said it was okay."

"What?"

"Well he really wanted a child and he wanted her to be the mother. So yeah, it made sense to keep doing it. They needed a sperm donor anyway and at that time, IVF wasn't really all that reliable yet. Plus her reputation would be destroyed if I released those pictures. They were… very compromising."

"So he was just okay with it?"

"Well not really. But he didn't have much choice."

"And the pictures?" Makoto pressed on.

"Well once I figured out he knew, I told her to bring him along for some of our sessions. And take some pictures as a memento."

"How long?" Kotonoha asked, her voice quivering.

"It took seven months before she got pregnant. The first time. For the second child it was only once. Assuming she's mine. I'm not really sure. She could have fucked around with other people. By then she was quite the whore."

Kotonoha tried to stand up, but Makoto held her down.

"Really," Tomaru continued. "Once you release their inner whore, all these sluts are the same. They just want a hard cock in all of their holes."

"That's enough," Makoto said. But Tomaru kept going.

"You did a decent job training her. But she's clearly still resisting you. You should fuck her ass. Really put her in her place."

That finally snapped Makoto. He grabbed Tomaru's bathrobe.

"Careful now," Tomaru said. "You wouldn't want me to spill everything, would you?"

Something shifted in his eyes. "We're leaving."

"Huh?"

Makoto grabbed her hand and dragged her outside.

"Makoto, we-"

"Shut up."

He opened the front door and walked out. Kotonoha was pushed back into the car.

Makoto slammed the door shut. He walked around the car, got in the driver's seat and drove off fast. Kotonoha didn't even have time to get her seatbelt on. She tried to, but her fingers were shaking too much.

Makoto took over. She heard a click.

"Why didn't you-"

"Just, don't, okay?" Makoto said. "He's still my dad. Even if he is…"

"A monster?"

"It doesn't matter. Your mom is… she's gone. What's the point?"

"Revenge?"

"Yeah, sure, and then he'll call the cops and you'll get fined for assault. And then, the cops will call your parents, realise they can't reach them and start to wonder why you don't have parents or a guardian. You ever thought about that?"

"No," she admitted.

"Officially your dad is abroad and your mom is sitting at home. We can't do anything that draws attention. This one trip was already super risky. Or did you forget you told him your mom is dead?"

Fuck. He was right. She shouldn't have said that. If Tomaru started to ask questions…

"I-I'm sorry," Kotonoha said.

"Leave the talking to me next time."

"Okay," she mumbled.

A silence fell. Neither of them asked the obvious question.

What now?
