A/N: So the last two chapters were about Saya and Haji's relationship specifically. This chapter is about their conflict with those around them, or rather the conflict they face as they try not to be indecent or improper or showing any displays of affection to Kai. They fail.

Coincides with the short story "Obvious" in the Short Stories chapter of Life Goes On, though there are a few extra incidents included because why not.

As for why they're hiding their relationship despite everyone knowing it's a thing, it will be delved into a bit here with why they don't want Kai to know. The next chapter (I may split it up) will explain why Saya doesn't want the girls in her life to find out. In general, though, I think they've just been through so much together that they do not feel there's any major change in emotional depth. And then there's the slightly selfish reason that they were both raised with 19th century ideals about sex and relationships in general, so they try to hide the fact that they're doing things that would've been considered improper back in the day. They don't do a good job of hiding it.

Evenings at the Omoro

(Or: Five times Kai interrupted his sister and one time he was not the pervert)

Saya got a mischievous grin on her face as she sat on the couch. Only a few weeks ago she kissed Haji over the counter to show off to his groupies. A few months ago they had rekindled their relationship at Julia's apartment. Although they had only had one short week in New York to bed each other since then, Saya had become more desperate to spend as much time with him as possible. She knew that her hibernation was delayed but not stopped. Now she wanted to take advantage of every minute they had free from Kai, so when he had announced he was going out Saya knew she had to take the opportunity.

It wasn't that Kai didn't know about their relationship, she was sure that he did, it was that Haji and Saya agreed to hide any relations from him. He was annoying enough about it when Haji had returned, but if he found out that they were sleeping together. God help them both. The teasing would never end. Haji always said he suspected the teasing came from Kai being a virgin. Saya doubted that was true, but Haji and David seemed to get a good amount of entertainment from it.

Getting up from the couch, Saya snuck into the kitchen where she knew Haji would be. Haji feigned surprise as she wrapped her arms around her back to drag him into the family room with her. She gave him a slow, simmering kiss. Haji, despite his common sense, went along with her wishes. He slipped his tongue into her mouth as he lowered her back onto the couch. They knew if they wanted to do anything more they would have to go up to Saya's room, or better yet spend the night elsewhere, so they were content to lay on the couch kissing.

Too distracted to hear Kai come in the back door, the couple continued their activities until Kai made a point to interrupt them. "If you're going to act like a couple of horny teenagers can you at least take it upstairs?"

Horrified at getting caught, but not wanting to show it, Haji slowly got up and ignored Kai on his way back to the kitchen. Saya blushed profusely, but remained on the couch until Kai walked out of the room. She then slowly walked up to her room. They blew that one.

Three nights later, while Kai was working through the dinner rush hour with his hired help, Haji was helping Saya with her summer break homework for school. He felt inadequate due to his lack of knowledge about science, but helping Saya out helped him to learn what he had missed out on learning previously.

Suddenly Saya called for a bathroom break and ran out. That appeared unusual to Haji – usually she just went. He followed her to wait outside the bathroom in case she needed him for anything, but she came out as normal a few minutes later. In the silence of the hallway, Saya contemplated why Haji waited outside the bathroom. Recently he simply waited in her room. Then again, she usually did not run out or yell that she was going. Had she worried him?

Slowly Saya lifted her hand to touch Haji's cheek. "Did I worry you? I – I'm sorry about the rush. I'd just been putting it off, so I needed to go badly."

Haji stared at her blankly. He would have understood back at the Zoo, but he hadn't needed to use the toilet in over a century. It figures he wouldn't remember what it felt like to be in her predicament. "No, it's okay," he said before turning away, embarrassed about getting worked up over nothing.

To apologize for worrying him, Saya stopped his progress back to her room and gave him a sweet kiss. She did not expect him to grab her back and kiss her with equal ferocity, but she did not complain. They both wanted as much time together as possible before she went to sleep, so it was good to finally see him taking advantage of a situation.

They began, as usual, with kissing. Soon Haji had moved down from her mouth to her neck, giving her butterfly kisses. One hand remained nestled in her hair while the other began to work its way up her shirt to get to the clasp of her bra. Although he'd never admit it, Haji was very proud of himself for mastering the ability to remove bras and would use it whenever he had the chance. Just as he was about to use the ability, a disgusted noise came from the top of the stairwell. Haji snapped his head away from Saya's neck to look towards the noise.

"Seriously. I did not need to see that," Kai said as he stopped his premature unzipping of his trousers in anticipation of his own bathroom run.

"And I did not need to see that," Haji said, looking to Kai's unbuttoned and partially unzipped pants. Saya buried her head in Haji's chest to muffle her laugh and dragged Haji back to her room. Kai grumbled as he made his bathroom run more hastily than he planned.

Haji and Saya intended to remain in her room for all further inappropriate activities, thinking it would stop Kai from walking in on them again. So far it had worked. They finally managed to get around to having sex one night without Kai's knowledge a week or two after Kai had caught them in the hallway.

Saya was far too tired to get into her pajamas, so Haji lent her his dirty shirt to wear to sleep instead. He helped her put in on, as she was already half asleep, and put his trousers on so he could be decent enough if he needed to leave the room to help Saya's nieces in the middle of the night.

Around 6 AM, with a half hour remaining until he had to work, Haji left to see to Kanade and Hibiki. Tending to them took longer than he thought, so by the time he could return to Saya's room to change for the day he was running late. The exact moment he leaned down to give Saya her good morning kiss, Kai stormed into the room.

"Why're you late Haji? We have a big rush this morning," Kai said without bothering to look at what was going on inside of the room. When he finally bothered to see the position Haji and Saya were in, he silently left.

It was safe to say after that rude awakening Saya had woken up. Haji helped her dress before dressing himself, and they both sheepishly went down the stairs to help Kai out. It was the least they could do for offending him so early in the morning.

Only a day later Kai found himself walking in on them again. Haji and Saya had spent their evening practicing with daggers on the roof, and both had decided to change out of their exercise clothing at the same time. That was not unusual. What was unusual was that Haji accidentally ran into Saya on the way into her room.

She fell onto the floor with her legs in the hall and her torso inside her room. Haji followed her down and landed on top of her. They both began to laugh freely, with quick pecks on the lips and cheeks interspersed. Neither noticed when Kai, alerted by the thud, looked around the hallway's corner to catch them.

This time, instead of interrupting them or showing exaggerated disgust at their affection, Kai soaked in their joy with an odd fascination. He couldn't remember the last time he heard Haji laugh, if he ever had, and they were not doing anything entirely disgusting. Yet. When he finally saw Haji's hand move to her butt, he made a point of walking by but did not speak. By Julia's estimate, Saya had no more than a month before she went into hibernation. No matter how disgusted he was, Kai had little desire to prevent them from forming happy memories before that happened.

A week before she went into hibernation, Saya was having trouble taking her nightly baths without falling asleep. Secretly, she'd always wanted Haji to bathe with her. They had only done it once before at the Zoo shortly after Haji had come, and then Haji had had to bathe her. He wasn't allowed in the tub. This time, Saya had a legitimate excuse, and Haji could not defend himself from it by saying it was improper. If this was improper, what was everything else they'd done naked with each other since his return?

After making sure Kai was asleep in bed and filling up the tub, she went about her plan. Without any words, as usual when she was trying to convince Haji to do something he may object to, Saya began to lead Haji to the bathroom. Shedding her clothes into the hamper, she was a bit surprised to turn around and find Haji still there. He hadn't began to remove his clothes, but she would fix that. Using her naked state as a distraction, she tackled him to the floor and immediately got to work on removing his button-up shirt. When he moved in an attempt to get up, her mouth went to his, distracting him with kisses.

Finally Haji came to his senses and remembered that he had so little time left with her for some time. Saya lifted her hips as he moved his hands down to remove his pants and helped to throw them into the hamper with her clothes.

He picked her up in an attempt to playfully dump her into the bathroom before she reminded him that this was a Japanese-style bath. Haji never did understand what that meant, so he usually used the shower off of Kai's master bedroom to bathe. Seeing his confusion, Saya took the time to sit him down and wash him off as was expected before any soaking happened. With a kiss, Saya indicated that she was done washing him, and he turned to do the same for her.

After all of the suds were washed off, he picked her up and carefully placed her in the tub. Haji slowly entered and sat on the opposite end of the tub. Their legs intertwined in the center of the tub. Instead of taking advantage of the situation, Saya and Haji talked as they soaked. They didn't address their past, deciding that the next few years of Haji's life were more important. When the water got colder, Haji pulled Saya in between her legs and wrapped his arms around her waist. From then on, they sat in silence, sharing nothing but the occasional quick kiss. Feeling Haji beginning to get excited, Saya turned around once more to initiate a much deeper one.

As this was going on, Kai woke up. The toilet in his en suite bathroom was clogged, so he had to trudge down the hall to the bathroom Saya used. He heard soft noises coming from the bathing room, but assumed the door was closed. It was midnight after a long day, so he didn't bother to check if he was correct.

Only when he sat on the toilet did he realize the noises were moans. With some measure of sick fascination, he turned his head to where the bathing room door was. It was wide open. Through it he saw his sister – naked – making out and grinding against her chevalier – equally naked. In his sleepy state he could not decide if he should move or not. Was it better to sit here and listen to his sister have sex in the same bathtub he used to bathe her nieces, or to move and risk tipping them off to his presence? He had his answer when he turned his head back to see Haji sitting on the edge of the tub and Saya sinking herself on his… Despite all the horrors he'd seen, that was probably the one he most wanted to wipe from his mind. Kai ran from the room and vowed never to use that bathtub (or that toilet) again. It wasn't worth it to tease them about this. Remembering it, even for that purpose, would probably scar his mind.

Soon after Saya fell into hibernation and Haji had left for his own purposes, Kai found himself betraying his sanity and drunkenly relating the bath tub incident to an intoxicated David. They were not necessarily good friends, but they did meet to talk about their lives. As much as they clashed during the battle with Diva, afterwards they realized there were some things they could only share with each other. To let these things out, David would come to the Omoro once a month or so to share a beer or two (or three) with Kai.

Tonight, Kai had started his fourth, and David was well into his second. Both had apparently seen too much since they last met in July. August's meeting had to be cancelled due to Julia and David's son's birth, so September's dragged two months' worth of stories into the fray. Hence, Kai telling David about walking in on Haji and Saya in the bathtub. What Kai hadn't expected was that David would have a story of his own about the two he drunkenly called "the horny teenagers." Understandably, David had to chug the rest of his second beer before beginning his story.

"It was when we were in New York. You know I went with on that, right?" Kai nodded. He hadn't known, but it made some sense. "So, for god knows what reason the UN guy who's supposed to be making sure they don't kill anybody thought it would be a great idea to bug their hotel room. He didn't care about my warnings that they would probably be either acting like annoying tourists or sex-starved newlyweds. I mean, he went all the way: HD cameras, microphones, door monitors. I have no idea what he thought he would catch." Kai knew where this was going, but he didn't ask David to stop. That was definitely the effect of the alcohol.

"Probably them being boring. What moron would think they'd kill someone in their hotel room? They're not Diva."

"Anyways. I was having a late night meeting to brief him on our plans for the next day to investigate the facility. He kept his laptop with the AV feed running just in case Saya or Haji made a 180 degree change of character during our meeting. We both turned our heads when the door opened and closed on the monitor only to see them violently ripping each other's clothes off. The pervert decided to keep watching."

"Well, did you?"

"Yeah. We'd had a bottle of wine before the meeting, so I was just intoxicated enough to decide I wanted to see how the hell Saya and Haji got blood on the ceiling of Julia's guest room when they banged there."

"See, you're the pervert! At least I ran away."

"And I never did find out how that happened. All I found out was that Haji has a penchant for feeding from Saya's thigh."

"I really, really did not need to hear that," Kai spat out in disgust.

"And I did not need to see that. I shut the laptop immediately after and insisted on another bottle of wine. I mean, Saya's not my sister or daughter, and she's twice as old as our ages combined, but she still looks under aged. And Haji's my friend – I did not need to see him naked no matter how well-endowed he is." Kai was sure if they were sober David would have a look of shame on his face. He was probably only telling Kai this due to the alcohol. "That was a far more regrettable choice than anything I did to stop Diva."

Kai had to agree.

A/N: What did I just write? Why did I just write it? Is everyone a pervert? I should probably just stop when I'm ahead here…
