Work Text:
Sebastian scrunches his nose. The residue of the Confringo spell mixed with the scent from the burnt spiders persistently linger in the air. He dusts off his robes and walks towards the edge of the rock walls.
Forbidden Forest is damp and foggy after the previous day's rain shower, but Sebastian still skips Charms to drop a visit anyway. He spots the exact things he is looking for on the ground and smiles.
"Sebastian." A voice calls and the brunette turns around. He recognizes the silhouette right away.
"Ominis." Sebastian says. He rubs the back of his neck, feeling annoyed. "You followed me, again." He wonders how Ominis manages to find him everytime.
"I had to." He says. The blond boy appears through the fog, approaching him with determined footsteps and his wand out. His expression is a mixture of worry and disappointment, it aggravates Sebastian even more.
He holds his hands up, although he knows the gesture means nothing to Ominis. "I'm not doing anything terrible, I promise. I'm just looking for some Ashwinder eggs." He explains nonchalantly, but Ominis is relentless today.
"What for?" The other boy asks coldly.
Sebastian rolls his eyes. "For Garreth Weasley. He needs some fresh ones to brew an Edurus potion. Not everything I do is related to dark magic, alright?" The Gryffindor had promised him something dark art related in exchange for the eggs, but Ominis doesn't have to know that.
He still looks troubled, however. Sebastian notices his shoes and the edges of his robes are covered in mud. He knows how much Ominis hates being dirty, but he still looks for him anyway.
"You weren't in class or down at the Undercroft...I was worried." Ominis says and Sebastian is immediately hits with a pang of guilt. He sighs and places a hand on Ominis' shoulder, squeezing it.
"I know, and I'm telling you that you don't have to be." He assures him again. Noticing the sun coming through the trees above them, an idea comes into Sebastian's mind. "Should we walk around for a bit until dinner time? You already followed me here anyway and the weather is nice."
Ominis stands still, deep in thought. He finally sighs. "Fine, but not in this forest."
"Deal."
---
They walk to a more open path. It's still secluded and away from the main road, but at least there's no more spiders around. The sun is beaming now and there's no trace of a single cloud.
Sebastian is twirling something between his fingers as he walks through the tall grass. He looks back at Ominis, who is following him. The boy has lost weight since their adventure to the Slytherin's Scriptorium a couple weeks ago. The night terrors are back and Sebastian can see the dark bags under Ominis' eyes becoming more prominent. It's never his intention to hurt those around him while he tries to save his twin sister. Ominis must know that.
Sensing Sebastian unmoving form, Ominis stops in his tracks and tilts his head. His foggy eyes blink under his long lashes. Before he can say anything, Sebastian takes a step closer and tucks the thing he's been holding behind Ominis' ear: a small yellow flower.
"For you." Sebastian says, somehow feeling apologetic.
Ominis raises his hand to touch it. His face reddens wonderfully when he recognizes what it is. "Oh." He mumbles.
"Looks pretty on you, Ominis." Sebastian feels his cheeks heating up too and looks away in embarrassment.
They stand in silence for a good moment before Ominis says, "...thank you." He then clears his throat. Sebastian takes that as a sign to keep walking, and so he does.
As much as Sebastian enjoys being in Hogwarts, sneaking into the Library's restricted section and devouring every single book in there, he also appreciates the time he spends outdoors. Outside the castle's walls, he and Ominis have the freedom to be themselves. They don't have to worry about keeping up appearances, Ominis especially, because of his family background. They've always been close. Things like kisses and hand holds feel natural to them. And although they never go beyond that, Sebastian is satisfied with the pace of their relationship. Once he finds a cure for Anne and they graduate, he can start to pursue Ominis in earnest. They'll have all the time in the word to do anything they want.
The boys continue to walk under the warm sun, until Sebastian notices something from the corner of his eyes. "What's that?" He asks, quickly walking towards it. He goes outside the path and stops in front of a tree.
"What is it?" Ominis asks as he approaches Sebastian and kneels next to him.
In front of them is a thorny tall plant with a big purple flower at the top. Sitting under the petals are large glowing pods covered with pulsing membranes. The thing looks more like a creature than a plant. "Some kind of a plant I've never seen before. It's...glowing." Sebastian eyes it carefully, trying to identify it.
Ominis furrows his brows. "Sebastian, I don't think this is a good idea. It might be poisonous.'
"It smells really good." Sebastian says, suddenly smelling vanilla beans emitting from the center of the flower. It then changes to the smell of herby tea Ominis often enjoys and Sebastian is reminded of the Armotentia potion he tried to brew once. The scent puts him at ease, he can't tear his eyes away from the glowing pods. He wants to touch it with his finger, for some reason.
"Maybe don't touch it." Ominis warns.
Sebastian touches it.
It explodes with a silent puff, dropping a big pile of glittery golden powder right on top of Ominis' head, covering him. "Ugh, Sebastian!"
"Oops! Sorry, I got it all over you." Sebastian says, half worried, half thinking it's funny. The powder is all over Ominis' hair and shoulders. He pats them away and Ominis does the same. "It smells amazing right?" He asks again.
"You moonmind! Get this off me." Ominis yells, looking irritated. Sebastian laughs lightly, but makes sure to remove most of them. "We don't know what it is or what it does." Ominis grumbles and then suddenly looks horrified. "Am I covered in boils? Rashes?"
"Erm...No, you're not." Sebastian shrugs. Ominis actually looks good with glitter and a small flower on him, he internally decides. "Do you feel anything?"
Ominis shakes his head as he tries to clean up the last bit of the sparkly powder on the inside of his collar.
"Well, that's good, then. It's just a strange plant." Sebastian says too casually. Ominis huffs in annoyance and stands up straight, "I need to shower. Let's head back."
"Yes, let's go." Sebastian nods as he eagerly scoops the fallen golden powder into a jar for further study. "Sebastian, put that back!" Ominis yells, but the brunette already places the jar inside his cloak.
"It's for science, Ominis!" He explains away, like usual.
---
Their walk is pleasant. Sebastian finds a long wood stick on the ground and uses it to poke things he finds interesting along the way. He's in a good mood. Not only he gets the Ashwinder eggs he was looking for, he also has a new thing to investigate. It isn't until halfway through their walk, he notices Ominis has fallen significantly behind. The boy's shoulder is hunched and his steps are wavering. Sebastian jogs towards him.
"Are you alright?" He asks, noticing the sweats and redness on Ominis' face. When the boy doesn't answer, he becomes even more worried. "Ominis?" He tries again and places a hand on his forehead.
Ominis flinches and mewls at the touch. "Sebas- I'm-" he gasps. The brunette retracts his hand in surprise.
Did he just mewl?
"You're feverish. Are you hurt?" He asks as he guides his friend to sit under a tree, eyes scanning for any clues. Ominis drops to the ground, his wand laying abandoned on the grass. His fingers scrambles onto his cloak and he takes it off.
"I feel like...I'm burning. I need to-" Ominis mumbles frantically. He peels off his vest and shirt, exposing more of the sweaty, pale skin underneath. Sebastian's jaw almost falls to the ground when he sees Ominis takes his whole top off. He is not ready to see his first love like this.
"Wait! Wait, Ominis!" He yells, face red in embarrassment as he tries to make Ominis put his clothes back on. The blond boy refuses and retaliates by taking off his belts and pants too. He kicks his shoes off, almost hitting Sebastian with his knees. "Ominis, snap out of it!" He tries again desperately and Ominis finally stops moving.
It is too late, however. Sebastian realizes that Ominis is already nude, except for his socks and his underwear. His usually neatly combed hair is now disheveled and all of his clothes are scattered around the ground. Sebastian's face turns completely red, his ears are burning. His cursed eyes travels from Ominis' aroused face, down to his heaving chest and then the rest of his alabaster skin. He's beautiful and Sebastian has to remind himself to breathe again.
"Stop staring." Ominis scolds him, his hand hovers above his own hard erection in a ridiculous attempt at modesty.
"Sorry." Sebastian gulps, noticing a particularly interesting mole on Ominis' left hip. "...It's the plant. It's making you like this." He slowly concludes.
"Oh, do you think so?" Ominis asks loudly, sarcasm and anger dripping from his voice. "Fix this, Sebastian! This is all your fault."
"Alright, uh..." Sebastian rubs his face with his hands, trying to think clearly and not be swayed by his emotions. But he takes one look at Ominis' red, panting face and all of his logic goes out of the window.
"...Well, the powder seems to have an aphrodisiac like effect on humans. I can see it being used by some beasts in the forest during their mating season, since it can increase their sexual appetite." He explains and Ominis balks at his words. Sebastian uncooperative eyes landed at Ominis' manhood again and he instinctively licks his lips.
"Anyway, seems like that's the only physical effect it has. So, uh, maybe, we can just...try to ride it out?" He suggests innocently.
"Ride it out?" Ominis repeats, dumbfounded. He launches at Sebastian, grabbing his collars in fury. "Have you gone ma- nnh-!" He suddenly whimpers when he feels another wave of pleasure hits him.
He moves back and props his back against the tree, breathing heavily. Sebastian can now fully see his almost naked body and hard erection. Tears are forming at the corners of Ominis' eyes. He looks as terrified as he's aroused. "I don't know what to do...Sebastian, I dont-." He mumbles deliriously, making Sebastian's head foggy.
Sebastian leans towards the other boy, pushing his body so he lies on the ground. "I've got you. It's alright, Ominis." He whispers and pulls down his underwear, revealing the already slick erection. Sebastian strokes Ominis' cheek with his finger, feeling the heat radiating under his skin. He lets it trail his neck and watches his adam apple bobs, then down his arm until he captures his wrist. Ominis shudders when Sebastian finally guides his hand further south.
"Place your hand here. Wrap your fingers around it." Sebastian says and Ominis does. He lets out a moan and bites his lower lip. Sebastian wraps his hand around Ominis' and starts moving their hands up and down.
"Stroke it, take your time. There you go." He whispers directly to Ominis' ear this time. The blond boy spreads his legs wider in return. Their hands make dirty sounds as they work together and Ominis is clearly embarrassed by them. "Sebastian, this feels wrong, I-" Ominis tries to speak, so Sebastian picks up his pace and rub the tip of Ominis' manhood with his thumb instead.
"No, this is right, Ominis. This is how it should be." He says as he twists his wrist and tightens his grip. The boy writhes under him and comes right away, cumming all over both of their hands and his stomach. Sebastian doesn't stop stroking, he continues to work on Ominis' pulsing hot length, giving him time to ride his climax.
Ominis' body drops back to the ground. He breathes hard as Sebastian kisses his cheek and praises him. He waits patiently for Ominis to gather himself. They stay still and for a second. Sebastian figures that the effect of the powder is gone, but he cannot be more wrong.
Ominis slowly sits upright and starts to kiss him hard. He slips his tongue in. Sebastian quickly snakes his arms around Ominis and kisses back eagerly, enjoying the heat coming from Ominis' skin and mouth.
They're both breathless when they finally breaks the kiss. Sebastian doesn't know if it is the golden powder or the teenage hormones, he has never been this horny in his life. He knows he need to keep himself under control before things go to far, but then Ominis pulls him close and decides to shatter his mind by whispering, in a wanton voice he never heard before, "It itches...inside. It's-"
Sebastian's eyes glaze with lust. "Inside? Where inside?" He asks, voice low. His hands travel down knowingly until they rest just above Ominis' buttocks. Ominis lets his head drops on Sebastian's shoulder, fingers clutching his shirt . He trembles and answers quietly,
"...In there."
Closing his eyes, Sebastian sighs in defeat and lets out a chuckle. He must be insane, for thinking he has chance against Ominis in the first place. "Merlin, Ominis." he trails off as he push Ominis to lie down again and lifts his legs.
"Hold your legs up with your hands." Sebastian says, drinking in the rare view, searing every single detail of Ominis' nude form into his memory. "Spread them wide, that's it."
Sebastian then places his two fingers inside Ominis' mouth, telling him to suck. He smiles when Ominis wet his fingers eagerly. He looks perfect like this, under him, pliant and obedient. There's no traces of stubbornness or embarrassment left in him; his mind is empty and his body is chasing for more pleasure.
Once his fingers are coated with his saliva, Sebastian pulls them out and presses one of them in front of Ominis' entrance. To his surprise, it already feels wet. He pushes his finger in and it slides inside very easily. Ominis' inside is soft and warm and Sebastian concludes that it must be one of the plant's side effect as well.
The blond boy gasps at the friction and moans. "Ominis..." Sebastian whispers, as he starts to move his finger. Slowly at first, before adding a second one, opening him up, drawing up more mewls and whimpers.
Ominis arches his back, his manhood is hard again, bobbing and dripping as Sebastian's fingers work inside of him. The broken moans coming out from Ominis' lips everytime he hits his sweet spot only spur him on.
Sebastian can tell that Ominis is close by the way his hips chases his fingers recklessly. "Next time, next time, Ominis, I'll put something else in here and I'm going to make you lose your mind." He promises and Ominis moans loudly. Sebastian leans in closer, pressing his cheek against Ominis' wet one. The boy has been crying from overstimulation. "I'm-" Ominis chokes out.
"Go on, come." Sebastian commands and bites his ear lightly.
Ominis does so instantly.
----
"What time is it?" Ominis asks, voice hoarse.
The sun is completely gone, replaced with stars and a cloudy night sky. It's getting a bit chilly and Sebastian has Ominis wrapped in both of their cloaks.
Truth to be told, Sebastian has no idea. They didn't stop until Ominis passed out and the whole ordeal felt like an eternity. Currently, there's no more trace of the plant's effect on Ominis. The boy is back to his usual controlled self. It's both impressive and scary, how Ominis can just turn it on and off sometimes.
"It's way past dinner." He guesses and he nuzzles Ominis' hair. The blond boy is lying next to him, head resting on Sebastian's chest. "How are you feeling?" He asks.
Ominis props himself with his elbows. "I'm alright." He answers and then he blushes. "But it's sore, down there."
Sebastian's eyes widen and he strokes Ominis' butt cheek lightly. "Sorry." He says, pinching it.
Ominis swats his hand away and sits up properly. He looks for his wand and sighs in relief when he finds it. "Should we head back to the castle?" He asks, sounding sleepy. The cloak on his shoulder slids down, revealing his pale body underneath. Sebastian lazily connects all the dots on Ominis' torso, making a star map out of them. His eyes then land on his groin, mostly covered with dark shadow, and they stay there.
"I still have half a jar of that powder left-"
"Sebastian!"
