"So what is this surprise of yours?" Makoto asked.

"You'll see."

"But I need to put on my trunks?"

"Yes."

"Hm. Okay then."

Makoto went upstairs.

Kotonoha got undressed and put on her bikini. She put on a bathrobe above it and tied it. Then, she grabbed two towels.

Luckily, she didn't have to worry about Kokoro-chan. Her little sister was on a sleepover with a friend of hers.

Not that she minded if Kokoro joined her, but…

Makoto entered the living room again.

"Okay, I'm ready."

"Let's go then."

"Go where?" Makoto asked. "Our pool is outside. It's freezing."

"You'll see."

Makoto followed her.

"Oh, the sauna?"

"Maybe."

"I have to admit," he said. "It sure is convenient to have your own sauna."

"Yeah," she agreed.

"But how is this a surprise? I already knew we had one."

"You'll see."

They entered the sauna. Kotonoha put a towel down.

"Have a seat please."

Makoto sat down.

Kotonoha stood in front of him. She untied her bathrobe and let it slide down her body. It pooled on the floor.

His mouth fell open.

Kotonoha blushed. "What do you think?"

He stared at the tiny white string bikini. It barely covered the essentials. And not just that, the fabric was incredibly thin. If it got wet, it would become completely translucent. And that wouldn't take long.

Kotonoha put the other towel down on the bench in front of him. She sat down.

"You didn't answer my question," she reminded him playfully.

"I… wow. It's amazing."

"You want to save it to memory?"

"What do you mean?"

Kotonoha put her lip. "Look in the pocket of my bathrobe."

Makoto checked. Inside, he found a tiny camera in a case. The kind that was used for underwater filming.

He looked up, unsure. "Kotonoha?"

She looked away. "If… If you want to film me, I wouldn't mind."

"Really?"

"Yeah. Just… don't go too far please."

"Hm. Well why don't you open those legs then?"

Kotonoha inhaled sharply, but she obeyed anyway. Obeying came naturally to her. She hardly even thought about it.

There was already a tiny white spot on her bottoms.

Makoto pressed the button. A red light started to blink, indicating he was saving this for posterity.

Somehow, it felt like it became even warmer in the sauna. Sweat started to form on her brow and between her breasts. She watched as a drop fell on the floor.

In barely a few minutes, her bikini became completely translucent.

Makoto put the camera down on the bench. The red light was still blinking. However, he angled it away from her, towards the back wall.

Weird. Had he gotten bored of her?

Makoto answered her question by standing up. He walked towards her and held out his hand.

She took it and allowed him to help her up. Right away, he wrapped an arm around her and pulled her into a deep kiss. Kotonoha tilted her head back and eagerly kissed him back.

Looks like he had decided to give a little break. It was one thing to film herself in this bikini, it was a whole other thing to film… that.

Although ironically, she had a video of him fucking Sekai in the Break Room.

"Jump up," Makoto said between kisses.

"Huh?"

"I got you."

She jumped and wrapped her legs around his waist. Makoto put his hands on her butt to hold her up. Now, they were on the same height, which made it much easier to kiss.

While he kissed her, she felt him move. However, she was too busy playing with his tongue to really question it. It was only when her back hit the wall when she realised what his purpose was. She was back in the angle of the camera.

"M-Makoto-kun."

"Shh. Don't mind that."

"I…"

It was hard not to. She could see the red light blinking.

"This is your fault," he said. "Look how hard you made me."

She looked down. There was a clear bulge in his shorts.

Kotonoha bit her lip. "Sorry."

"You better take responsibility."

"W-What would you like me to do?"

Makoto took the strings of her bottoms and pulled. The knot got loose. He easily pulled off the bottoms completely. They were soaking wet.

"Open your mouth," he said.

She opened wide.

Makoto stuffed the drenched bottoms in her mouth. She tasted a mixture of sweat and her own fluids.

"Don't take those out," he warned her.

Kotonoha nodded. She felt a mixture of fear and anticipation. She had already forgotten he was filming all of this.

Makoto untangled her legs and put them down. Her knees were shaking, but they held her weight.

He calmly pulled out his cock. It was already completely erect.

How… how was he gonna fuck her? Should she turn around?

He grabbed one of her legs and pulled it up.

Woah.

She grabbed his shoulders to stabilise herself.

Now, one of her legs was held up beneath his armpit.

He maneuvered around and managed to push his cock inside her soaking wet pussy.

Kotonoha's moan was muffled by her bottoms.

They had never done it in this position before.

He wasted little time in going to town. Kotonoha threw her head back in bliss. It had been so long since she had felt his cock inside. She had missed this so much.

He was hitting all the right spots. Because it had been a while, she could feel the delicious pain of her pussy stretching to accommodate his cock. Her breasts bounced freely in the flimsy bikini top.

He pushed her harder against the wall. Makoto reached down and started to kiss her neck. The kisses soon turned into sucking.

No, wait.

He was gonna leave marks. And in her neck, everyone would see.

Fuck.

She was gonna cum. And yet she couldn't. There was no way to ask for permission with her mouth gagged. He had explicitly told her not to take them out. Her approaching orgasm was hardly a reason to disobey his order. Besides, there was nothing in her ass, so she couldn't come anyway.

Kotonoha tried to speak with her mouth filled, but only muffled grunts came out.

"I can't hear you," he said with a smile.

Fuck.

He fucked her even harder.

Hold back. Hold back. Don't come. Please…

Wait a second.

She wasn't the only one getting closer. She recognised his grunting. He was getting close to. And if he came inside of her…

She shook her head and pleaded with her eyes.

Don't. Please don't. Anywhere else is fine, just not inside.

He just grinned. "Something wrong?"

Left with no choice, she reached down and pulled his cock out. Then, she dropped down on her knees and jerked him off.

"Fuck."

Kotonoha closed her eyes. She felt his cum shoot on her face. Her left eye was hit, forcing her to keep her eyes shut.

"Well done," he praised her. She felt his thumb wipe away the cum from her eyes. Then, he pulled out the bottoms from her mouth.

Kotonoha opened her eyes again. "Thank you."

"You're not done yet," he reminded her. Makoto pushed his semi-erect penis in her mouth.

Kotonoha eagerly sucked him.

He let her suck for a bit longer as they both calmed down.

"Okay, that's fine," he told her eventually.

She gave one last reverent kiss on his cock. Then, she lied down on the floor.

Makoto went to lie with her.

He put an arm around her and pulled her close. She put her head on his chest.

He held her for a long time in silence.

Then…

"We should go to a public pool with you wearing that bikini," he said.

"I… what?"

"Why not?"

"But… everyone will see."

"See what? That you're a beautiful girl?"

"I… you know what I mean," she said.

"Come on," he said. "Do it for me."

"I am doing it for you. Only you. Is… isn't this enough?"

A silence fell.

Kotonoha started to get worried. Would he be angry at her? She had said she'd do anything for him. Multiple times. And yet…

Was this really such a big deal? If… if he wanted to show her off then…

"I-"

"It's okay," Makoto said. He smiled. "Just wear your normal bikini."

"O-Okay."

For some reason, she felt like he would make her wear her white bikini anyway.

But she was wrong. Very wrong.
