"Come on," Kotonoha said. "What's your surprise?"
"You'll see," Makoto said. He put the car in fourth.
She pouted.
"You'll enjoy it," he assured her.
Kotonoha looked over her shoulder.
Sekai and Kokoro were both sleeping in the back of the car.
It had been a few days since their incident. In the end, Sekai had decided to go with her mom to France. She didn't have much choice after all.
But she wouldn't tell anyone about Kotonoha's parents. Partly because she loved Makoto, but probably more because she was scared as hell about the tape leaking out.
Sekai was leaving tomorrow. For their last day together, Makoto had promised to take them somewhere, but he wouldn't tell where.
"There we are." Makoto turned the car and slowed down.
Kotonoha frowned. "The beach?"
"Yes. I figured we could go for a swim."
"But I don't have my bikini with me," she argued.
"I guess you'll have to swim naked then."
She blushed. "In front of them?"
It was a bit weird she was embarrassed about that. After all, she had already had a few threesomes with Sekai. And she was training Kokoro to please Makoto-kun as well. So this shouldn't be such a big deal. And the beach looked deserted.
"Why not?" Makoto said. "You would do it if I asked you to, right?"
"I guess," she said slowly.
"You guess?"
"Uhm. Of course I would. I would do anything for you."
"Good. Don't worry. I've got your bikini in the back."
She let out a breath of relief.
He looked back. "We're here," he announced.
"Huh?"
They both woke up.
Kokoro's face lit up. "Awesome."
They all got out of the car.
Kokoro ran towards the water.
"Wait," Makoto said. "Put on your swimsuit first."
"You have it with you?"
"They are in the trunk."
He moved to the back of the car and opened the trunk. Then, he handed everyone their swimsuit.
"Can we change somewhere?" Sekai asked.
"Just do it right here. There is no one around."
She briefly hesitated, but then she started stripping. Kotonoha followed her example. It was no big deal, she told herself.
Makoto started to get changed too. But Kokoro hesitated.
"Come on," Kotonoha urged her. "Get changed."
"Right here?"
"Don't be embarrassed. It's just us."
"Okay then."
Kokoro got undressed too.
Makoto sneaked a couple glances at her.
This was so wrong. She should be mad at him looking at her sister like that, and yet, she didn't mind for some reason. It even excited her to train Kokoro to please him.
Makoto helped Kokoro in her swimsuit.
"Thanks," she said. She leaned in to kiss him on the lips like Kotonoha had taught her.
It looked very exciting.
Kotonoha forced herself to calm down a little.
When they were done changing, Kokoro was wearing a one-piece blue swimsuit, Sekai a blue-white striped bikini and Kotonoha the red bikini she had bought with Makoto ages ago.
"I want to go swimming," Kokoro said.
"Not alone," Makoto said. "Sekai, can you go with her?"
"Okay."
"Come on, Onee-chan," Kokoro said. She took Sekai's hand and dragged her to the water.
"I guess we'll sunbathe for a bit then," Makoto said. He took out two towels and a bottle of sunscreen.
They walked a bit from the car and put their towels down.
"It sure is quiet here," Kotonoha said. The beach was completely deserted.
"Yeah," he said. He handed her the bottle of sunscreen. She got the hint and rubbed it all over his body.
When she was done, he returned the favor.
He stayed silent until he reached her back.
"You're gonna get tan lines," he said. Without waiting for her reply, he untied the laces of her top.
"Makoto," she weakly protested. She used her hands to press the top against her breasts.
"You don't want tan lines do you?"
"No," she admitted.
"Well then. What do you say?"
"... Thank you."
"Good girl."
He smeared the sunscreen over her back. When he was done, he moved forward.
"Hands away," he ordered.
"But-"
"Now."
Hesitantly, she moved her hands away, along with the top of her bikini. Then, without being told to, she turned around.
He applied the sunscreen on her chest, taking a lot more time than was necessary. When he was done, she was already wet and her nipples were hard.
"There we go," he said.
"Thanks."
Kotonoha quickly got back on her belly. She knew she wouldn't be allowed to put her top back on, so she figured this was the best way to hide her chest.
However, he wasn't done with her. Makoto sat on his own towel and looked at her. He had a playful look in his eyes.
"You look sexy," he said.
She blushed.
"Hm."
"What's wrong?" she asked.
"Spread your legs more." He moved to sit behind her.
"Uhm, okay." She wondered where this was going.
"Move your panties to the side," he continued confidently.
She blushed. "Now?"
"Yes, now."
"O-Okay."
With a heavy blush, she pulled her panties to the side, exposing her pussy and ass to him. She avoided his burning eyes on her.
"Look at me," he ordered.
She looked back to him.
He had a smirk on his face. "Play with it."
"They are right there," she argued.
"Fuck them. Do it."
She was startled, but then, her body obeyed. With her left hand, she kept the panties to the side. With the other one, she touched her pussy lips. Her fingers quickly found her clit and traced lazy circles around it.
"Good girl."
There was a tugging feeling in her belly. She loved being his good girl.
This was so wrong. Her sister and best friend were right there in the water. But if it was wrong, then why did it feel so right?
"Push in a finger."
She pushed her middle finger inside. It slipped in easily.
"Get it nice and wet," he said.
Where was he going with this?
Kotonoha pushed her finger in and out. It couldn't get any wetter. Her pussy was nice and slippery. She was ready to take his cock. But he had other plans.
"Now move it up."
Up? Where to?
She pulled her finger out and moved it up.
"Higher."
Kotonoha hesitated.
"What are you waiting for?"
"But that's my…"
"I know what that is."
She bit her lip. "I've never played there before, Makoto-kun."
"I know. But you're gonna do it. Right now."
"But-"
"You want me to do it?" he warned her.
"No, please."
"Then do it. Now."
Slowly, she moved further up right… there.
Fuck.
Kotonoha traced the wet finger around the rim of her ass.
"There you go."
It felt surprisingly good. It was very dirty, but that only made it feel better.
"You're mine," said. "Completely."
"Yes," she breathed. She really wanted to be his.
"Every part of your body is mine."
His words were intoxicating. She felt herself drifting off.
It became easier and easier for her to drift away like this. Maybe because it had been a while since she last came?
When was that? When was her last orgasm? She didn't remember.
"Push it in."
This was so dirty.
And yet, she couldn't disobey him.
Her finger slowly forced its way inside her virgin ass.
By far the most humiliating part was that she was the one doing it. It was one thing to allow him to do it, it was something else entirely to lie here on the beach and finger her own ass for his viewing pleasure.
Once it was in, she held it there, trying to get accustomed to the weird sensation.
He gave her a few seconds to adjust. Then…
"Deeper."
She pushed harder. Her finger slid in to the second knuckle.
"There you go," he praised her. "How does that feel? And don't you dare lying to me."
"It feels weird. But good," she admitted. It hurt a bit, but somehow, that made it feel even better.
Makoto reached out and rubbed her pussy.
She moaned loudly.
"Look at you. You're practically gushing."
"Sorry," she mumbled.
He pushed two fingers into her pussy and fingered her. Sloppy lewd noises came out of it. Kotonoha kept her finger in her ass. He hadn't ordered her to take it out after all.
Makoto added a third. He quickly found her G-spot, which earned him a loud moan. "You're such a slut. Getting off on this humiliation."
Kotonoha was too embarrassed to reply.
"Aren't you?" he pushed her. His thumb rubbed her clit.
"Yes," she blurted out. "I'm a slut."
"Good. Add a second finger, slut."
She pushed her index finger in her ass as well. It painfully stretched further.
She was embarrassed to admit that she had to hold off her orgasm. She didn't know whether it was him playing with her pussy or her playing with her ass. Maybe both? Maybe the humiliation? Maybe all of it combined?
It didn't matter. What mattered was that she held back and didn't cum without permission.
"How long do you think it will take me to get your sister to do this?"
Oh fuck.
"I… I don't know." She slowly pushed her two fingers in and out of her asshole. He hadn't told her to do that, but she couldn't help herself.
"Maybe I'll let you watch. If you're a good girl."
"Oh fuck."
"Language." He accentuated his words with a slap on her butt.
"Sorry. Can I just… please." She fingered her ass even faster.
"Please what?"
"Please can I cum?"
"Go ahead." He removed his hand from her pussy.
"Ah, I…"
"Come on, cum. I said you could, now do it."
"I can't do it like this." Just her ass wasn't enough. It felt amazing, but his thumb on her clit and his fingers on her G-spot where what got her close. And what distracted her from the pain and humiliation of her virgin ass stretching out around her own fingers.
"Oh, that's too bad," he teased her. "I guess you don't really want it then."
"No, no. I do. Please touch my pussy again."
"No," he said. "I want you to cum from your ass alone."
"Then give me your cock," she begged. "Please."
Kotonoha grabbed both buttcheeks and spread her ass for him.
This was crazy. Just a couple minutes ago she was an anal virgin, and now he had reduced her to a wet begging mess.
"Sekai is coming back."
"What?"
She turned. Sekai and Kokoro were indeed walking back to them.
She quickly fixed her bottoms.
Unfortunately, there was no time to put on her top again.
"Hey, Kotonoha. Having fun?"
"Y-Yes," she said. "Just sunbathing a little."
"You need to come swimming with us, Onee-chan," Kokoro said. "The water is warm."
"O-Okay. Can you hand me my top?"
"What do you need your top for?" Makoto asked. "There is no one here."
"Yes, but…"
"You two don't mind, right?" Makoto asked the other girls.
"Uhm, not really," Sekai said.
"Why don't you take your top off too?" he suggested. "That will make her feel more comfortable."
"Okay."
Sekai removed her top and tossed it aside. She made no effort to hide her breasts.
"Come on." Sekai held out her hand.
Kotonoha awkwardly took it with her left hand and allowed Sekai to help her up.
Sekai frowned but said nothing.
"Let's go."
They walked towards the water.
