Their footsteps were silent as they walked down the hall, wary of making any noise. If they got caught, Sebastian would kill their ass.
Niko let out a slow breath as the prefect passed by the library doors, walking towards the stairs. Disillusioned, they snuck behind her, slowly opening the door and slipping into the library with her none the wiser.
They kept up the disillusionment charm as they weren’t sure if the librarian had left yet and weren’t willing to risk it. What the hell did Sebastian want now, in the middle of the night? Niko was going to kill him.
Hearing footsteps, they ducked behind the shelves. Fuck, she was here. They watched the librarian warily. They just needed her to go away from the restricted section so they could get in.
Easy
. They were going to kill Sebastian.
They held their breath as Scribner walked to her desk, muttering to herself. If she had caught Sebastian and Niko already had snuck all the way down here,
they
were going to kill Sebastian’s ass.
They weaved between the shelves, charm still up, moving closer to the restricted section. They really needed to figure out a way to get in without her notice. This better be worth it.
They whispered a silent apology to the library before casting depulso on a cart of books. They winced hearing the books get thrown off the cart, but quickly and quietly cast alohomora on the lock, catching it before it hit the ground.
Sneaking in wasn’t an issue, it was trying to take a book without permission that was. Luckily, they didn’t need a book. Just needed to find their dumbass boyfriend.
They cursed quietly to themself as their charm wore off, placing the lock in their pocket. They ducked behind a shelf, crouching behind it. They’ll lock the door back up when they leave, if they remember.
They recast the charm, sneaking through the area. They knew Peeves was distracted up by Gryffindor Tower, so hopefully the little bastard wouldn’t appear again. If he interrupted whatever Sebastian saw to be
so important
they would find how to exorcise the little shit.
Niko walked silently through the halls, avoiding the ghosts and armor suits with a practiced ease, finally reaching the room where Peeves had found them the first time. They could see Sebastian sitting on the floor, leaning against a broken cabinet. He looked smug. Niko was going to kill him. They canceled their charm.
“Why the fuck did you call me down here at like three in the morning,” Niko hissed, crossing their arms. Sue them, they were tired. Fuckin’ insomnia. And Sebastian. Fuck Sebastian.
Lovingly
. The bastard knows how they get without sleep.
“Hello to you too,” Sebastian teased, patting the floor next to him. Niko rolled their eyes but sat down next to Sebastian, leaning against the cabinet as well.
“Going to answer my question?” Niko sighed, leaning their head back and mostly closing their eyes. They could still see Sebastian out of the corner of their eyes.
“Where’s the fun in that?” Sebastian’s smirk was both annoying and hot. Fuck him. Stupid pretty bastard.
Niko didn’t get the chance to respond before Sebastian was straddling them. Their eyes jolted open and their hands flew up to grip Sebastian’s hips. They tilted their head to look into Sebastian’s eyes, mouth open in surprise. Their brows furrowed after a moment, realising what Sebastian wanted.
“Really?! Here?!” Niko hissed, feeling their face heat up. Fucker always made them blush so easily. Not like it was difficult when they weren’t used to compliments or being flirted with.
Sebastian put his arms around Niko’s neck, as if sensing their trailing thoughts, leaning in with that infuriating smirk. One of Sebastian’s hands was lightly scratching at the base of their scalp, causing them to bite back a moan.
“Why not?” Sebastian damn near purred, causing them to shudder. “You like it like this, don’t you?” Niko looked away, letting out a shaky sigh, trying to control themself. Unfortunately, this meant that they weren’t looking at Sebastian, and thus were surprised by lips against their neck.
Niko slammed a hand against their mouth, muffling the whine they let out. They closed their eyes tightly as Sebastian continued to kiss over their neck, gently nibbling in spots he knew were sensitive. Niko didn’t want him to stop.
They relaxed into Sebastian’s hold, tilting their head to allow more access, ignoring how they could feel Sebastian smirk against their neck. They gripped Sebastian’s hip harder, digging their fingers into the soft flesh like they knew Sebastian liked. They were rewarded with a soft moan against their neck.
One of Sebastian’s hands came from around Niko’s neck to pull their hand off of their mouth, gripping it tightly. Their conjoined hands fell to the side, gripping onto each other like they’d never get to again.
Sebastian’s other hand moved up to dig into their curls, pulling slightly. Niko let out a choked whine that Sebastian captured with his mouth, desperate and eager.
The kiss was both sweet yet rough, both gentle yet forceful, all in the way only Sebastian could do. It was addicting, Sebastian’s lips against theirs, better than any drug.
They were gasping for air by the time Sebastian pulled away, faces still close. They couldn’t breathe, Sebastian’s presence was so loud in their mind, it was all they could focus on. It’s all they ever wanted to focus on. That and Ominis. Merlin, Ominis would kill the both of them if he heard what was happening.
They pulled their hands away from Sebastian’s hip and hand, sliding them under his shirt to grope at his chest. Sebastian let out a shaky moan at the touch, helping them by taking off his shirt.
They pressed their face into Sebastian’s chest, ignoring the surprised noise he let out, kissing and biting gently on the flesh before them. They loved leaving marks, a possessive side to them purring with pleasure as they did.
They wrapped their lips around one of Sebastian’s nipples, nibbling and sucking on it. Sebastian moaned loudly, hands digging into their scalp. Niko pulled off with a pop, moving to the other to give it the same treatment.
Before they could do much, Sebastian yanked their head back by the hair, making them let out a lewd moan. Sebastian looked like a mess, all flushed and hazy, chest covered in bruises. Niko knew they didn’t look much better.
“I hate how easily you take control,” Sebastian’s tone was light, amused more than upset. Niko sent him a lopsided smirk. Sebastian rolled his eyes, pulling Niko back into a bruising kiss, pulling away before they had a chance of taking control.
Sebastian gently cradled Niko’s face in his hands. “Let me take care of you,” he murmured, gently kissing over Niko’s freckles. They shuddered and nodded, letting themself relax and go pliant, letting Sebastian do whatever he’d like to them.
Sebastian smiled, soft and warm, making their face flush more than they realized it could. They leaned into Sebastian’s hands, relaxing at the touch. His hands were always so warm—his touch always so
safe
.
Sebastian helped them up, pulling them into the closet next to them. Quickly, Sebastian helped them out of their clothes, piling them up next to them. It was odd being naked when Sebastian was still, mostly, dressed, but they trusted him.
Sebastian stood before them now, staring at their body like he had never seen it before. Niko froze up as they realized why, muscles tensing. They usually had glamours up when getting undressed in the dorms, covering all of their scars. It didn’t matter when they were dressed as their clothes hid them, for the most part, so they usually let them fall.
They hadn’t thought about it as they were usually the one in control, or at least had some control. They knew what was happening, what would be done. They hadn’t been expecting this, and had been too tired to think about putting up their glamours.
They looked to the side as they felt Sebastian’s eyes roaming their body in silent horror, afraid to speak of it. They didn’t want Sebastian or Ominis to see their scars—despite knowing they would eventually.
They flinched slightly, looking back over as they felt Sebastian’s hand on their chest, over one of their scars. Sebastian hadn’t noticed that he was under Niko’s gaze, too distracted by the mesmerizing pattern of scars.
“What…? Who would…?” Each question Sebastian started never got finished, he knew Niko would tell him when he was ready.
“If…you are rethinking this…” Niko muttered, voice low. If Sebastian was going to reject them over this, they weren’t going to let themself get hurt. They’ve been hurt enough.
Sebastian jolted like Niko had slapped him. “No! That’s not…I still want to!” He replied quickly, yet honestly, taking Niko’s face into his hold. Niko flinched but quickly relaxed.
“Sorry…I…” Niko wasn’t sure of what to say, and they could tell Sebastian wasn’t either. Sebastian moved closer, gently pulling them into a kiss that was so full of love and care it nearly made them start to cry.
Sebastian pulled away from the kiss but pulled Niko close, hands roaming across their body. Niko shivered in the cold air, pressing closer to him. They dug their hands into Sebastian’s back, craving the comfort and closeness Sebastian easily gave.
Sebastian carefully pulled them both to the ground, setting Niko into his lap. He ran his hands over Niko’s thighs, gripping and squeezing at the ample flesh.
Niko let out a quiet sigh, leaning their face against Sebastian’s shoulder. They wrapped their arms around Sebastian’s neck, gripping onto his back.
“I was going to ride you,” Sebastian murmured, causing goosebumps to erupt all over their body at the abrupt change. “But now, I’m more inclined to have you ride me.” Niko nodded, face flushed once more.
“Good boy,” Sebastian murmured, voice low and teasing. They knew that they wouldn’t escape talking about this later, but they knew Sebastian could tell they weren’t ready to talk yet.
Gods
, they loved him.
He had to move Niko off of his lap for a moment so he could finish getting undressed, grabbing out the little bottle of lube from his pocket. Niko snorted, unsurprised, as Sebastian sent them a little smirk.
Sebastian pulled them back onto his lap, guiding Niko’s head to rest on his shoulder. He gently lifted Niko’s hips, fingers now coated in lube and gently tracing around their rim, causing them to shiver.
Niko let out a shaky breath, burying their face into Sebastian’s shoulder as a finger pressed in, slowly. Their hands gripped at Sebastian’s back, trying to find some sort of stability.
A low moan escaped their lips, muffled by Sebastian’s shoulder. They shut their eyes even tighter, flustered beyond belief.
It wasn’t the first time Sebastian had done this—far from it—but they never failed to get flustered or embarrassed by his actions and behaviour. Another moan slipped from their lips as Sebastian pressed another finger in, slowly stretching them out.
They knew it didn’t take much for them to get overwhelmed, especially with such gentle touch. Sebastian knew it just the same, which was the whole reason he was going slow. They were already trembling in his grip, and it was mortifying.
“Must you…nngh…move so slow…” Niko mumbled, lifting their head a bit so they were speaking into Sebastian’s ear, purely to fuck with him. They smirked when he shivered.
“I want to take care of you,” Sebastian responded, face flushed. “Even if it means going slow. I want you to remember every second of this.” They let their face drop against Sebastian’s shoulder again, hiding their blushing face.
After what felt like an eternity, Sebastian slowly removed his fingers, causing them to let out a quiet whine of complaint.
“Alright,” Sebastian murmured. “Go ahead, sweetheart.”
