This was clearly not a “good brother” level, ok?!?

Noah sat curled up inside the huge bathtub underneath the warm water spray, hugging his knees to his chest.

The warm water droplets slid down his skin soothingly, thoroughly cleansing his every muscle and pore, washing away the fatigue and grime alike.

If only the water could also wash away his feelings. If only the pitter-patter sounds could also drown out his own thoughts. Alas, they were like a river suppressed by a dam for far too long. It pooled until it could no longer be suppressed. Then it all came crashing down. Deafening. Unstoppable. Inevitable.

Noah blankly stared at his pink toes.

And then, an image flashed in his roaring mind – an image of those toes stepping on Levi's chest.

Noah abruptly straightened out his back, moving his gaze away from his feet and settling it on his rising and falling chest.

For a moment, he was relieved. And then he saw a pink, puckered nipple… which Levi had accidentally grazed earlier.

Noah's body jerked, and he desperately buried his face into his arms, only for his eyes to inadvertently catch sight of what laid in between his legs. A dripping mess still flushed from the vigorous rub it had just received.

As if burnt, Noah's head flew away from his arms, his eyes darting around in a panic, looking for a safe place to rest them.

After several flustered rounds circling around the bathtub, he finally stopped them on his pair of bent knees.

…Knees that had been hugged by that strong arm as he had been…!

Noah's face flushed, and he dunked his head underwater until only his eyes were visible.

Damn it all! Now everywhere he looked reminded him of what just happened!!

○|￣|_

For a long while, Noah sat in the tub with only his eyes above water, blowing underwater bubbles to take his mind off things.

He had long finished washing himself, but he was too embarrassed to come out of the bathroom.

How could he face Levi after what just happened?!?

H–his body had responded in such a shameful way!!! And he didn't have an excuse of morning wood or being half asleep to fall back on!!!

Unlike Levi, who had his junk stroked in his sleep, he, Noah, was perfectly awake and aware of who he was doing it with!!!

And to make matters worse, Noah had even refused to service the other, only to end up getting serviced himself! It was him who got Levi all worked up but refused to help "solve" it. Yet, when Noah ended up getting a physiological response himself, Levi didn't count debts but magnanimously helped him out!

Besides feeling so embarrassed that death seemed like an easier way out, it also left him very conflicted. On the one hand, he didn't think that his world views and moral values were wrong; on the other, he felt that his brother was really treating him wholeheartedly, and he wanted to reciprocate his affection.

Now, in hindsight, he felt as if he hadn't treated Levi as well as the other treated him, and that left Noah feeling down.

He'd just have to treat him better in the future, right?

Easier said than done!! He currently couldn't even face him! And even if he could, how exactly was he supposed to treat him? As a good brother?! Fuck that! He had so many good brothers in his past life but had never done something shameful like that with any of them!!! This was clearly not a "good brother" level, ok?!?

But if it's not a good brother level, then what was it? What kind of relationship was beyond a good brother?

Noah resurfaced and leaned his back against the tub, staring at the ceiling without really seeing it.

No, his thinking had gotten sidetracked. What he should be doing right now wasn't to find a label for his relationship with Levi, but to understand what exactly happened earlier!

Why did he respond to his own brother in such a way? No – the better question was 'how'. How could he, an asexual worldborn, get a response down there?!

Levi was a normal human, so it was natural he would respond to being touched there. But the same rules did not apply to worldborn!

Worldborn had no libido! They felt no lust and, under normal circumstances, couldn't even get it up! Sure, they would feel that having their PP stroked was a bit pleasant, but it was far from enough to get them hard or even interested in the activity!

Yet not only did his little brother respond, but it even responded so enthusiastically!!! Leaking shameful juices everywhere!

How? How?! How?!?

(ノ꒪Д꒪)ノ︵ ┻━┻

…When in doubt, ask Blackie…

But how to breach this embarrassing topic?

In the end, after gnawing his lips for a while, he asked tentatively, "Blackie… did you see it?"

Blackie, who was eating metaphorical popcorn while replaying the video he had recorded earlier, snapped to attention. What did his host just ask? Did he see it? He glanced towards his host with suspicion. Was that a trick question? ಠಿ_ಠ

'It must be! But too bad, host! I shall not be fooled! I refuse to admit to seeing anything!'

"See what?" Blackie feigned ignorance.

Noah covered his burning face with his hands, "That… that what happened… earlier…" his voice tapered out until it became as quiet as a mosquito.

Blackie eyed his host strangely. He didn't seem to be probing?

Still, better be safe than sorry. If Blackie admitted to seeing and recording it all in his memory, wouldn't his host flip out of embarrassment?

Blackie internally nodded his head. Yep, better not tell him. Especially now when his emotions are already so volatile.

"What exactly are you referring to? I have a mature content filter installed for the sake of protecting my host's personal privacy. All I saw was a mosaic…" Blackie bullshitted without so much as a stutter.

Well, to be honest, there was some truth to that. He couldn't share any of his recorded memories with anyone without his host's permission. And while he didn't have a mature content filter, an AI system like him was basically a soul plugin. Since he relied on his host's soul to function, if his host didn't wish him to see or hear something, his sensory functions would be automatically blocked.

Too bad his host was too preoccupied doing this and that with his brother-in-law to give any thought to who else might be watching… ╮(╯∀╰)╭

And since he wasn't blocked from seeing it, why would he abstain from watching? Any qualified AI system knew that knowing more is always better! And that included hearing and seeing more!

(￢◡￢)

Don't misunderstand! It's not that he enjoyed watching naked humans go at it!

…Whether someone was naked or clothed made no difference to him. ╮(╯∀╰)╭

Either way, a non-human like him couldn't appreciate their humanly aesthetic.

Therefore, what he enjoyed wasn't porn. (︶^︶)ノ

But expanding his knowledge database. (☞ﾟ∀ﾟ)☞

And besides, he was just a machine; what's wrong with looking? Which human cared if there were TVs or toasters in the room while having sex?

It was his right as an intelligent toaster to observe his surroundings!

While Blackie was diligently feigning ignorance, Noah was clenching his teeth. This stupid system!! He was trying to be subtle here, but the other wanted him to spell it out!!!
