Author's Note: This story, along with others I will give credit to my lovely writing partner, is part of a weekly role-play session I have with my lovely Michelle (who is my Kaoru). If you ever have any ideas for prompts or story ideas, shoot me a PM because we are always looking for ideas!

Sorry this took so long! We're not done, though!

Exhilaration: Chapter Two

December 15, 2013

Kaoru was... leaving?

Was that a signal for her to follow?

She was going to follow regardless, like a lost puppy trailing her master. Nana quickly gathered her things before quietly exiting the classroom. She looked around, gripping her bag tightly, trying to figure out where Kaoru had disappeared to. She pulled out her phone and glanced at it, just in case he had texted her.

Kaoru had stopped right outside the classroom door, stepping just out of sight to look for a bathroom. As Nana exited the classroom (following much too closely; he'd have to scold her for that later), he grabbed her arm and put a finger to his lips.

He pointed to the end of the hallway where the girls' bathroom was, and then to the clock hanging above them: 4:40. They only had ten minutes until most of the nearby classes released. If they were going to fuck, it would have to be quick and dirty. Not that that would necessarily be a bad thing, of course. He nodded back towards the bathroom and raised his eyebrows.

Nana stepped closer to him, so her voice was hardly above a whisper. Her legs were shaking—she could feel them. She was so satiated and yet so wound up.

"This close?" she asked, eyes wide and looking around frantically.

Someone else would leave the class early, maybe following their lead; maybe someone would need to use the restroom while they were in it. They would be caught and their game would be over. Having sex when the hall was deserted was one thing, but with people so… so… nearby? Nana gave Kaoru a pleading look.

Kaoru shrugged. "Got a better place?"

If Nana didn't want to do it in the building, it wasn't exactly going to be a big deal, but that was kind of the point of the whole breather: hidden exhibitionism.

He looked at her again and reached up to brush the choker Nana had taken to wearing since she gotten the tattoo of his initials.

"Then again, maybe it's not up to you," he said, quirking an eyebrow and grinning, the frog-like smirk starting to slip out.

Nana gulped, the sound loud in her ears, as he pulled his hand away from her neck. He was subtly reminding her just what their situation, their honest relationship, was.

Pushing down her nerves, she glanced up at the clock in the hallway. "We'll have to hurry, then," she said, taking his hand and pulling him along.

Surprised that Nana was now taking charge, Kaoru dropped the smile and nodded dumbly as he followed her to the bathroom.

As they reached the door, he swallowed the temptation to hesitate. Instead, he pulled Nana into the bathroom alongside him, kicked open a stall, and locked it behind them.

He stilled for a second, listening. No one was there. His logical mind knew he should have let Nana go in ahead and check to see if it was empty, hanging outside and looking like that patient boyfriend, but they had a time limit.

Kaoru turned to Nana and grinned, leaning over her, running a hand down to her waist and hooking a thumb in the hem of her shirt. "Take it out, Nana."

She took a deep breath before reaching up underneath her skirt and pulling her panties down. Gingerly reaching in between her legs, past swollen lips, she pulled the bullet out. With a loud exhale, she held up the device for him, her cheeks a lovely shade of pink.

"Here."

"Still nice and wet, I see," he said, smiling as she held up the toy. "Works for me."

He leaned in to kiss her while unbuttoning his fly after stashing the vibe in his pocket. Kaoru pulled his dick out, giving it a few preliminary strokes; but he was so turned on, he barely needed to touch himself to get it up.

"Say when," he managed between kisses and pulled her against him, grabbing her hips and holding tight.

Nana was slightly surprised he wanted to attempt this standing up. They hadn't really tried it before, but… he had been getting stronger, working out in order to handle these kinds of things. She trusted him with her safety.

"One, two," she counted in warning before bouncing up into his arms. Grateful for his impossibly strong grasp, it took some maneuvering as she positioned him at her entrance, shifting clothing out of the way so skin could meet skin. Once she aligned them correctly, she ground down against his dick before holding onto him for dear life.

Nana let out a loud gasp, the feeling of this position different than what they normally did. Their location helped, as well.

Kaoru wobbled a bit at first, but managed to keep her hips in his grasp and his feet steady on the ground. "Shit, Nana," he managed. It took them a couple seconds to work our a rhythm between them, but by leaning back hard against the stall's wall, Kaoru was able to lift both Nana and his own hips to meet hers in relative tandem.

It was cramped and hot, but Kaoru couldn't be bothered to think about anything but how wet and tight Nana felt around him. This was the best idea he'd had in ages. They should skip math all the time.

Nana squeaked with every rough impact of skin upon skin, with each thrust. She tried to keep quiet, she really did, but it was incredibly hard to.

"Kaoru," she breathed, "harder. Come fast." Nana tried to keep up, to move with him. She swore softly, mouth against his forehead due to their angles.

Kaoru was only able to grunt in response to Nana's pleas. He was already so close and there was definitely no stopping now. The idea of her orgasming in class as a result to his ministrations, even remote, was powerful. He thrust raggedly into Nana, her breath hot on his face, his muscles straining to keep them both upright.

"Oh fuck, Nana," he gasped. Kaoru pressed his face into her shoulder and came hard, groaning and gasping. He had to steel himself to keep from completely dropping Nana and collapsing on top of her.

He pressed back against the wall and breathed deeply, sweaty and sated.

Nana was still aching and throbbing, but she had already come twice before so she was content with this situation. However…

"Okay," she began, carefully hopping down and grabbing some toilet paper to wipe herself off. "Pull up your pants and let's get out of here. Class has to be over by now!" she whispered.

Pulling up her panties, she righted herself before helping him along.

As Nana stood up, Kaoru slid down the stall wall and squatted near the bottom. No way was he sitting on the floor.

Nana was all business, but she hadn't just had a mind-blowing orgasm in a bathroom stall like he did. He looked at his watch. One minute until class ended. "Yeah, we'd better leave." He pushed himself up and pulled his pants back on, trying to ignore how worn he suddenly felt. He was going to feel that muscle strain tomorrow.

But… for now? Fuck it, time to get home for their unspoken round two—or was it three at this point? Kaoru opened the stall door and lead the way out of the bathroom.

"So, my place or yours?"

"Mine is closer," she said, glancing at herself in the mirror.

Lewd girl.

Sneaking out of the bathroom made her feel giddy and young. She loved that feeling.

"Is there more to our breather?" Nana asked.

She saw that Kaoru had stashed the bullet in his pocket, along with the dial, but said nothing else about it.

"More? You're pretty greedy today, Nana. Two orgasms and a quickie. Though, I think there's still room for more," Kaoru said, grabbing her hand as she looked in the mirror. He tried to flatten some of his hair with his other hand, but it didn't really work. Whatever, his hair wasn't exactly important.

He pulled the vibe from his pocket and handed in to her. "Stick this over your clit." He instructed and moved toward the bathroom door, opening it and smirking at her before he slipped outside.

"What? Now?" she gasped, stopping before she exited the bathroom with the vibrator in her hand. "Kaoru!" she hissed when he moved out of range of the bathroom door.

She whined about this not being fair. Nana pushed the bullet against her clit, wondering if it was going to slide around or get in the way in her panties. However, that's what Kaoru wanted. After doing what she was told to do, Nana slipped out of the bathroom in search of her mischievous partner.

Kaoru stood outside the girls bathroom, hands in his pockets, one foot against the wall, looking the typical boyfriend waiting for his girlfriend to finish up. The hallway was now crowded with people leaving class.

When Nana appeared again, he smiled sweetly and took her hand. "Ready to go?"
