The morning was bright as Eren opened his eyes. The warm, gentle sun rays flooding through the window and the light breeze swishing past the curtains in gentle-like manner. The birds were chirping merrily on the tree branch located just outside the window, receiving and replying the calls of other birds in their sweet-sounding voices.

It was a wonderfully peaceful morning. Nothing was better than waking up to this kind of happy sunny weather with the prospect of readying yourself for another healthy, active day.

On normal days, Eren would thought so. But today wasn't one of those normal days.

There was something obviously wrong in the way he stayed put in the bed even after already waking up half an hour ago, also in the way he persistently kept the covers in tact on top of his lower body.

There was also something wrong in the wild look on his face, his expression screaming as if it had just seen something horrible. The grip he had on the covers didn't slacken as he sweated over the thoughts in his head.

After a full minute, when he dared himself to look under the covers again, he realized something awful had just happened to him. There was no mistaking it. He could feel the wetness in his underwear, staining the cotton material till the wet patch was visible for his eyes.

And there was also the bulge that didn't seem to want to die down ever since he had woken up. It hurts and the pain was killing him. Suddenly feeling embarrassed thinking about this, his face flushed red and he slumped forward, pushing the pillow into his face while he rubbed his thighs together fervently. It felt hot underneath, kind of itchy and...and the friction the rubbing made was kind of nice. His face heated up even more as the pleasure took over his body, desire making itself apparent in the way he was feverishly moving his thighs now.

But then, it still wasn't enough.

To be honest, this was his first time experiencing something like this and he wasn't even sure what was happening to that part of him, as to why his body felt so intensely hot and so nice just from being rubbed indirectly there. In the end, pleasure clouded his mind and his body moved according to what it felt could give him more because he definitely wanted more in this state. This wasn't enough.

Eren slipped his hand into the covers, progressively making its way further downward till it slid through the hem of his underwear where he could feel the area underneath his fingertips intensified more in heat. Down there felt even hotter when touched. He was sweating now, body curled as he stubbornly kept himself hidden inside the cover while his hand touched that part inside his underwear which was wet and slippery by now.

His fingers run through the length carefully, testing waters. Until instinct took over and made his hand form a grip around it. He moved his hand clumsily and he could feel the slide of skin underneath as he pumped it slowly.

"Aaahh..." A moan broke through his lips, involuntarily. The sound was embarrassing and it was even more embarrassing just seeing himself doing something so unfamiliar like this in his own bed while being aware that people can come into his room anytime. But-but he can't left himself like this. He at least had to finish this off, that was what Eren thought as the pleasure began to spike with each pump of his hand.

In the end, he had to bit into his pillow when he couldn't bear it anymore. Something had come out. Breathless, as he brought his hand back up, he saw the white stains covering it. It was thick, sticky and...maybe it'd be better to not think further. Finally regaining his composure, he jumped out from the bed, hurriedly pulling off the sheets from his bed so that he can wash it because whatever that came out from him just now had came out a lot, and somehow stained the bed sheet. The thought of sleeping with the stains for the other night gave him shivers.

Keeping the sheets bundled in his arms, he hurried out of the room. Trying to be as small as possible as he snuck through the hallway, he wished no one was up and around yet to witness him like this. The washing room was downstairs, that meant he just had to go down the stairs now and passed the kitchen before reaching there.

However, he was stopped midway when he realized someone was in the kitchen. That person was sipping their coffee relaxedly while sitting on the chair. It was also so very unfortunate that that person happened to notice him passing by and stopped him with that very familiar monotonous voice.

"Oi, Eren."

At that time, all Eren could think was that he's in deep trouble. Frozen in his step and only able to mechanically turn his head as if it was made from some rusty creaking pivot, he tried to give his usual smile. But somehow it didn't feel right even to himself.

"G-Good morning, Levi-heichou..."

"Why are you in a rush so early in the morning?" If there's anything worst, it's the fact that the older man was now eyeing the bundle in his hand so intently. Eren could hear that fearful gear in the other's mind turning, deducing possibilities, probably could make out what he was trying to hide just by looking-

"Nothing! I just feel like airing the sheets out! It's been months since i've done that! Today feels like the right day! Yup, it's so hot outside, what better day than today to air the sheets out, right? Besides, i have so much free time to spend. Ahaha!"

Sadly, the act he hoped to appear normal didn't turn out that way. He was panicking in his mind and that probably showed on the outside too. He's never good in lying.

Levi's eyes were now both eyeing the sheets and him in suspicion.

He's so fucking ruined.

"You're hiding something."

"N-No. Hahaha...What are you talking about, heichou?" The look heichou gave him was scary. It kind of felt like he had grown submissive puppy's ears and tail as he shrunk into himself, feeling conscious. "A-Anyway, i'll go and do my work. I'll see you later, heichou." Bowing hurriedly, Eren left as fast as he can.

In the washing room, he scrubbed the sheets frantically, all the while hoping that Levi wouldn't try to confront him about it later, wishing that no one would even bring it up again because he definitely intended to forget whatever that had just happened to him.
