Mr. Smarty-Pants

Summary:

Sebastian's breath hitched, mesmerized while staring at the blonde's scarlet eyes, glowing in the lightly dim room. He could feel his chest rising and falling with each breath.

Without thinking, Louis leaned in closer, his lips gently pressing onto Sebastian's.

 

'Hold on hold on what the fuck..?!'

Chapter Text

William and Sherlock left the scene, leaving Sebastian with an unconscious body.

"Ah, now we got another one on the club right now.. How do I move you though.."

He brushes off some of the hair Louis had on his face, giving him a good look.

'He looks kinda cute.. And a tad bit familiar..'

"Welp, gotta save my ass from getting myself killed by William.." he scratched his head.

Sebastian lifts Louis up, then carried him to a spare room then tucked him to bed.

As someone who's had too many parties with an odd bunch of party animals like him, he's almost accustomed into giving aftercare when his friends have reached their limits in holding out their liquor. And this time was no different, especially after the (playful) threat William imposed on him, he also had no choice but to also take care of the younger Moriarty.

Not that he had much stuff to do next, aside from cleaning up after the party. He decides to stay and look out for the younger Moriarty to keep William's trust at the very least.

As he was about to leave, he hears rustling sounds from the bed, along with unclear murmurs.

"Hey Louis, you good there?" He approached him, giving a light touch on his forehead.

"Mmh.. Thesis.. done.." he whispered, which Sebastian thought it was cute.

"Huh.. Now I remember." he stands, looking down at him.

"You're that smarty pants from the MedTech department.." he scoffed.

"... Didn't know you had this gap moe in being drunk and sober."

"Nnghh.. William, my head hurts.." the blonde started squirming.

He chuckles, sitting on the floor, watching him with an amused smile. Sebastian liked these kinds of people when drunk, especially those quiet ones when sober, turned into adorable yappers. He just find them interesting.. and cute.

"Williaaam.. I wanna go home... Ermm.. "

Louis opens his eyes, his vision blurry and hazy, with the effects of alcohol making him unable to think straight, he was wasted.

"Ello good sir.. Have you seen.. My brother?" He looks at the distorted figure of a man in front of him. His hand does a little wave, while narrowing his eyes to get a good look at Sebastian with the absence of his glasses.

"Can't say I did, what does he look like?"

Sebastian smiles, playing along with the latter's adorable drunken antics.

"His name is William, a BS Mathematics senior, blonde hair, red eyes.."

"Hmm... Haven't seen him. I'll let you know when I find him, alright?" Sebastian chuckles, lightly pinching his cheek. Which earned him a little giggle from the blonde, and for some reason, it tugged a few of his heartstrings.

"Well, someone told me to take care of you until you sober up, so tell me if you need anything 'ight? I'll be by the door." He pats the drunken Moriarty's head. 

"Mhmm~ Okay~" the latter answers, giggling again.

"Haha, cute.." Sebastian chuckled under his breath then stands up, walking towards the door frame, leaning against it. Louis just looks at him from the bed, eyes glued at his broad back.

'Oh... He looks hot.'

He covers his reddening cheeks as wraps himself with a blanket, still staring at the standing Sebastian Moran from afar.

After a few minutes, Louis felt his lips getting dry and dehydrated. As he turned his head to the dresser, he reaches for the glass of water sitting on top. Sebastian hears faint rustling sounds on the bed and a few taps, as he turned, his eyes caught the blonde reaching for a glass of water while lying on the bed.

"Ah, stay in bed, I'll get it for you." Sebastian jogs back to the bed, reaching his hand out to help the blonde. But instead, he accidentally bumps the Louis' hand, causing the glass of water to spill on the carpet... And on himself.

"Ah, shit." Sebastian steps back.

"Wah, I'm sorry! I didn't mean to—" Louis gets up to apologize, abruptly stumbling after a pang of pain at the back of his head stung before he could stand.

The both of them fell on the floor with Louis on top of Sebastian.

"Agh, damn it. My head.." Sebastian hissed.

The dark-haired man's eyes widened like saucers, seeing the younger Moriarty laid on his chest.

"Shit, William's going to kill me—" Sebastian cursed as he tries to get up, only for him to get pinned down by Louis on top of him, attempting to get up as well.

"Huuuuh? William?" Louis pushes himself back up, feeling Sebastian's sturdy chest against his touch.

He curiously pressed his chest, slowly smirking at the blurred image of Sebastian under him, unbeknownst of the reaction the man wore on his face.

"What the hell are you doing..?" Sebastian whispered, yet his head was screaming prayers and curses.

'Holy shit William's going to kill my children'

'The fuck.. the fuck the fuuuuckkkk'

"Louis, you're beyond sober, please get up and lie on the bed.." he attempted to ask nicely— which obviously didn't work. 

The blonde just smiled as his hands continued on caressing his chest, slowly going down his finely-toned abs.

"Such hard and beautiful rectus abdominis.. Do you work out?" he traced his finger gently on Sebastian's abdomen, earning a grunt from the dark-haired.

"Louis I swear to God, stand up please. Please." the man was starting to turn red, feeling a tickling sensation from the latter's fingers circling around.

"Hmm.. Nope~" he smiled at him, his hands furthering down his thigh, caressing it slowly. Sebastian was quick to sit up and stop his hand.

"Don't."

"Why not?"

"You don't wanna do this."

"Do I look like I don't?"

"The fu— Argh.. Your brother's going to castrate me when he sees us like this!" Sebastian retorted.

"But you called me cute earlier" Louis' smirk widens, his other hand holding his chin.

"Y-yeah I find you cute, what about it then?" He pouts.

"You called me cute, I find you hot, isn't it a mutual understanding between us?" The blonde feels Sebastian's grip on his hand loosening up, as he continues on moving his hand on his thigh.

The dark-haired couldn't debate more with Louis. All he could do at this point was pray for his hand not to slip on the wrong area where all his blood drained into one spot.

They both stared at each other for a few minutes. Louis' hand slowly stroking his thigh, while Sebastian was trying his best not to look turned on at the blonde's teasing.

"S-stop it..." he groans.

"What? It's only your thigh. Don't tell me you're getting hard from just touching your legs?"

"I'm a guy, shut it. You know this is normal." He hissed.

The air around them was thick with tension as the two of them stood inches apart, their bodies barely touching. Sebastian's gaze lingered on his lips, which were so close he could almost feel them on his own. Louis' other hand slightly lifted his chin up and gently touched his cheek, tracing the shape of his jaw with his fingertips.

Sebastian's breath hitched, mesmerized while staring at the blonde's scarlet eyes, glowing in the lightly dim room. He could feel his chest rising and falling with each breath.

Without thinking, Louis leaned in closer, his lips gently pressing onto Sebastian's.

'Hold on hold on what the fuck..?!'

Curses flooded in Sebastian's mind, unable to move from the predicament he's currently in. He couldn't tell if he should respond to the kiss, or was he getting even more turned on, or was he about to lose his mind.

After a long while, their lips parted. Louis was pouting from the lack of response that the other man displayed, little did he know that he was only barely hanging on to the sanity he has left.

"You're no fun." He re-positions himself on top of Sebastian, slowly moving his hips and rubbing onto the man's hardening member.

"God.. I'm so dead after this.." the dark-haired let out a sigh.

Louis lets out a soft moan as he began to buck his hips against the Sebastian's, seeking friction and pleasure. He wrapped his arms around his partner, hands digging into his skin as he pulled him closer, wanting to feel his body against his own.

The blonde watched the latter's reactions, suppressing the ecstasy and pleasure building up in his libido.

"God, you're making me nuts.."

"First time?" Louis smiles.

"Definitely not." Sebastian groaned.

"Doesn't look like it.." 

"L-listen... You're that fucking smarty pants from the Medical Technology department, dry humping on my dick, on the fucking floor, and in my friend's dorm.."

"Okay, and..?" His hips began to move faster, his breathing growing shallow as he chased the sensation.

"N-nothing.. Just saying.."

A low, guttural moan escaped Sebastian's lips, burying his face in the crook of his neck as he feels himself reaching into climax.

The blonde's movements grew more urgent, his hips bucking against the other's as he neared the edge. With a final, shuddering thrust, they found their release, both moaning in unison.

"Ah, shit.. This guy really humped me dry on the spot..."

As the pleasure slowly subsided, Sebastian felt a wave of exhaustion wash over him. His eyes shifted back to the blonde, his breathing slowed, growing deeper and more rhythmic as sleep began to claim him. His eyes fluttered shut, and within moments, he was fast asleep.

"Hey, hey Louis... What the—" he shook the man, but to no avail, he was already exhausted of his energy. With the remaining strength he could muster, he lifts the unconscious young Moriarty's body up, then gently placed him back on the bed.

Sebastian could only click his tongue in frustration, looking down at his pants. A wet spot was evident near the zippers.

He licked his lips. Eyeing at the sleeping Louis' innocent face, as if he hadn't made such a seductive expression a few moments ago.

"Not bad for a nerd."
