Summary: A few drinks at the Three Broomsticks was meant to be harmless — until a game or truth or dare begins to blur lines and none of you want to stop.
"Sirona, can we get one more round please?" Your boyfriend, Sebastian, asked the owner.
The Three Broomsticks was busy tonight as it was Friday evening, so students were off for the weekend. You and Sebastian decided to spend your night sharing butterbeers, though a couple of shots of firewhiskey had also snuck in.
You were feeling warm and floaty by the time the two of you decided it was nearly time to head back to the castle — after one more glass of course. Sirona waved her wand and two filled mugs floated towards the counter you were sitting at. White foam peaked like snowy mountains over the rim.
"After this, we truly must go," you told him followed by taking a rather large sip. Unbeknownst to you, foam had smeared itself across your upper lip.
"Here, baby," Sebastian started, but stopped himself. Instead, he leaned in, running his tongue gently over your lip, taking every bit of foam with it. When he pulled away, his cheeks were red like the tie Sirona always wore.
"Seb..." you whispered as you felt the heat crawl up your neck and spread all the way to the tip of your ears. "Not here." Though you truly didn't mind. No one had seemed to notice and the alcohol was finding itself warming more than just your chest. Ever since the last shot of firewhiskey, you had felt the familiar ache blooming between your thighs.
It's why you were in such a hurry to leave — and why you assumed Sebastian was going along with it. Drinking always made him horny too, well...hornier. Ever since the two of you first had sex, he doesn't seem to be able to keep his hands off of you for very long.
The bottom of your glass came quicker than you anticipated and Sebastian wasn't too far behind you. He had one, maybe two sips left.
"I'll take our tab now, Sirona," he spoke.
Sirona turned around to count the amount of drinks the two of you had shared. Sebastian never let you pay either, so you stopped trying a while ago. Your efforts always seemed to be in vain. "That'll be five sickles."
He reached into his pocket, but leaned in to whisper something to the woman. By the grin on her face, you knew whatever he had asked had been cheeky. He handed her far more than five sickles, she snuck something back, and he hurried it inside of his jacket. "Are you ready, sweetheart?" He asked.
You nodded your head and took his hand in yours. It was soft all around, minus the callouses on his palm. It enveloped your hand nearly whole as he used his free hand to push open the wide oak doors of the pub.
The evening air greeted you kindly as the wind gently caressed your cheeks, sweeping your hair back. But after sitting for so long, the alcohol was now catching up to you. The first step you took on the cobblestone path was clumsy, almost as if you had stepped on a loose stone. Though, you wished that had been the case.
"I forgot you can't hold your liquor," Sebastian teased, dramatically holding you up.
"I so can, just a misstep that's all," you replied smugly.
By the time you were out of Hogsmeade, your walk was better, but your thoughts were not. "Have I told you how handsome you are?" You asked.
"Only about ten times since we left The Three Broomsticks."
That earned you an honest laugh from him — it was beautiful. It warmed your chest more than alcohol ever could.
"What did Sirona sneak you," You asked now that you were all alone on the road back to Hogwarts.
"Just a little something to keep our evening going. I figured I could sneak you in my dorm tonight." He opened his jacket to show off a bottle of firewhiskey.
"It's Friday night, he should be out doing something."
"You must not know Ominis as well as you act."
The rest of the walk back was giggle-filled as your bodies became looser from the drinks.
"After you, my love," Sebastian spoke as he held open the large doors for you.
"Why thank you, kind sir."
It wasn't a far walk to the Slytherin common room, the problem was sneaking you in to his dorm. It was easier than sneaking him into yours though. You both learned the hard way when the stairs slanted and turned into a slope, causing Sebastian to slide down on his ass. But alas, prefects still existed and even though stairs didn't change when you went to his dorm, it was still heavily frowned upon — especially with firewhiskey in the mix.
Sebastian whispered the password and the serpent slid up the wall with a hiss, transforming the once bare brick into a large door for the two of you to walk into. Right away you were met with the sweet smell of mint, the smokey wood from the fireplace, and damp stone. The common room was one of your favorite places to be, especially with him. You loved cozying up with him on a plush chair in front of the fire with a good book, or staring out into the Black Lake out the enormous windows — though that one did take you a minute to enjoy because someone thought it would be funny to trick you into thinking you could see mermaids.
When the coast was clear, Sebastian ushered you along down the long, winding stone hall into his shared dorm with Ominis. Ominis had grown to be one of your best friends at Hogwarts. The two of you had grown quite close during your fifth year and the relationship stayed strong throughout the years, even through all of the gray hairs you and Sebastian gave him.
You both tumbled in the door while giggling over your victory only to find Ominis sitting up in his bed, scanning through a History of Magic textbook. "You two are back earlier than anticipated," he said without looking up.
"We just um — wanted to come back early to study," Sebastian lied.
Ominis laughed. "You must take me for a bigger idiot than I thought."
The three of you laughed together now. "Fine, we just wanted to come back for some proper drinking." Sebastian pulled the bottle of firewhiskey from the inside of his coat. Ominis couldn't see it, but he knew the two of you better than anybody, he knew what was there.
"I'll just retreat to the Undercroft then. I would hate to intrude on your… studying." Ominis stood from his bed and started gathering up his things and putting them into his leather satchel.
"You could stay, you know," you said before he got too far into packing.
Sebastian turned to you and nudged you softly, but enough to get your attention, enough to know he wanted you alone tonight. But you felt bad kicking Ominis out of his own room.
"What?" You mouthed to him.
"Trust me, I would rather be in the Undercroft," he laughed.
"See?" Sebastian mouthed to you, but still, you felt guilty.
"Maybe we could play truth or dare?" You suggest. "I dare you to stay. See? Now you have to."
"If only it worked like that, darling, but I wasn't playing," Ominis quipped, now walking past you and heading towards the door.
"That's not a bad idea, Ominis. It could be fun," Sebastian chimed in.
"I told you, Omi! You should stay."
For a moment, he pondered. You really thought he was about leave you and Sebastian hanging despite your efforts, but he turned around and set his satchel back on his bed. "Maybe a few rounds, but no stupid questions. I'm looking at you Sebastian."
"I haven't even done anything yet," Sebastian replied.
"That's the keyword: yet."
The three of you sat on the floor on the ornate green rug between the two, four-poster beds. Sebastian set the bottle of firewhiskey down and reached into the trunk at the foot of his bed to pull out an empty bottle from your last drunken evening.
"Who wants to start?" He asked.
"I guess I'll spin," you said. The bottle spun between the three of you, landing on Ominis. "Truth or dare Omi."
He thought a moment, as if he didn't know better than to choose truth. "Truth," he finally spoke.
"Hmm. Is it true Sebastian irks you to no end?" You snickered.
"Hey!" Your boyfriend snapped jokingly. "What kind of truth is that?"
"The honest one. Yes," Ominis laughed before spinning the bottle, landing on you. "Truth or dare."
"I dare you to roast Sebastian."
"What is this, pick on Seb day?"
"Yes," you both replied in unison.
He grumbled and rolled his eyes lovingly, waiting for your roast.
"Ooh, I've got it! You're lucky you're charming because Merlin knows you're not making it on common sense."
Ominis bursted out laughing, the hardest you'd seen in a while, but Sebastian still sat with his arms crossed over his chest.
"Rude," was all he could muster up.
"Remember when you called me ignorant?" You reminded him.
"Sebastian, truth or dare?" You asked, disregarding the empty bottle now.
"Dare," he said, wiggling his brows at you.
"I dare you to... kiss me for ten seconds."
"Make it fifteen," he quipped.
"Oh for Merlin's sake," Ominis grumbled. Sebastian's lips captured yours in a hungry kiss. It started off sweet, but he was greedy when it came to you. After a few seconds, his tongue found its way into your mouth, swiping over yours. Your lips moved in sync as his hand found the back of your head. "Time." But you didn't stop. "Bloody hell, I said time!"
The two of you pulled apart finally as Ominis cleared his throat. Sebastian rubbed his thumb over the wet spot he had left behind on your bottom lip, pulling it down and staring at you.
"The two of you make me glad I can't see."
"You love us, Omi," you sang.
After a few more rounds of lighthearted truths and dares including Ominis having to stand on one leg for one minute and you admitting to your desire for the Defense Against the Dark Arts teaching position, lines started to slightly blur.
"I dare you to sit on Ominis' lap until your next turn," Sebastian had said, which had taken you by surprise, but you weren't one to back down from a dare.
Ominis was very handsome you had to admit. Sebastian had your heart truly, there was no doubting that, but you still loved Ominis deeply.
You sat down on his thigh and it was awkward at first. Ominis had no clue what to do with his hands and you were still wearing your uniform which included a skirt, so your bare legs were pressed against his trousers.
"I don't bite, you know," you whispered to him, easing his hand to rest across your waist. "You don't have to be shy with me. Ominis, you're next. Truth or dare?"
But before you could ask what his deepest fear was, Sebastian cut in. "Is it true you fancy my girlfriend?"
"Sebastian!" You whisper-yelled.
You felt Ominis' leg tense under your bottom and his grip on your waist get tighter, like he was holding on to whatever restraint he had left. "I —"
"Just tell the truth, mate."
"I knew it!" Sebastian exclaimed. He wasn't angry like you had expected. Perhaps the whiskey was getting to him more than you thought.
And sweet Ominis, his cheeks were redder than your phoenix's feathers. You couldn't help but lean over and press a gentle kiss to his warm face.
"Can you just go now Sebastian? Truth or dare?" Ominis muttered.
Now it was your turn to cut in. "What made you think Ominis fancies me? Why would you ask him that?"
"That's two sweetheart, but for you I'll answer. He always knows it's you when you walk into a room, I know he does. His shoulders always relax and he breathes a sigh of relief. He thinks I don't notice, but I do. And he's so gentle with you. He's never been like that with anyone, not even Anne. And I asked because I just needed to know the truth."
"Is it true Omi? Can you tell it's me when I walk in?"
He looked as though he didn't want to answer, like he had already exposed to much of himself to the two of you. "Yes," he sighed. "Your footsteps are more graceful than any I've ever heard. And your perfume enters the room before you do, vanilla and cinnamon. It reminds me of a bakery." He smiled to himself and breathed a tiny laugh. But his confession warmed your heart more than you would care to admit.
"You're so sweet Omi, I knew you were secretly a softie."
"Bleh, now I'm gonna vomit," Sebastian said. "Truth or dare, baby?"
"Dare." You said while getting off of Ominis' lap since it was your turn again already.
"Now I dare you to sit on my lap for... two turns."
"Oh you cheeky devil," you teased before crawling across the rug to sit on your boyfriend's lap. You realized now though that you were just as comfortable sitting there as you had been sitting on your friend's. You also realized your boyfriend was already growing a erection under his pants, bulging at the seams, and pressing lightly against your underside. The realization made your core ache.
A few more truths and dares went around the room. Sebastian had to admit when he first fancied you (when you knocked him on his ass your first day of classes by the way) and Ominis had to walk across the room without his wand.
More drinks were passed, blurring the lines even further, but you never would've guessed Sebastian's next dare for you. "I dare you to kiss Ominis," he had said with darkened eyes.
"What?" You asked in confusion.
"I dare you to kiss Ominis. He fancies you... why not?" He acted like you kissing his best friend was the most natural thing in the world. He wasn't the normally protective/jealous boyfriend he usually was tonight, something had gotten into him.
But when you looked across the room at Ominis' shy demeanor, you took notice again at just how handsome he was. He couldn't see you as you crawled back towards him slowly, but you knew he felt your presence with his other heightened senses as he turned his lips towards yours as you neared closer.
"Have you ever kissed anyone before Ominis?" You asked.
"No," he whispered, his minty breath colliding with the cinnamon of the whiskey filled your lungs.
"Yes," he whispered again.
You stayed on all fours before him as your lips brushed gently against his. They were soft and warm. You licked once across his bottom lip causing him to gasp, allowing you full entrance into his hot mouth. Your lips collided with his delicately, but he was a quick learner. Soon, his long, bony fingers found their way into your hair as your lips started to move together in harmony.
After about ten seconds, you pulled away, but not before pressing one more quick peck to his now swollen lips.
You scooted backwards until your bottom found its place back on Sebastian's lap. At this point, you weren't even sure if the dare was still going, but his lap was your favorite place to be.
"Truth or dare, Ominis?" Sebastian asked, but Ominis was still lost in your kiss. "Hello? Earth to Ominis."
"How was our kiss?" You asked, secretly eager to know. You had plenty of practice with Sebastian, but you wanted an unbiased opinion.
"It was... lovely," he gulped.
Next Sebastian had to close his eyes and try to walk across the room with Ominis' wand, which he failed miserably at. Though one could blame the alcohol — he did anyways.
The three of you had made it a ritual at this point to end each round with a swig of whiskey. You thought your hearing had gone out when you heard Sebastian's next dare. You giggled, shifting yourself on his lip, ready to get to the real dare. "Oh come on, be serious," you said.
But he had been. Very serious.
"I dare you to touch yourself," he whispered directly into your ear, his breath curling around your throat, sending shivers down your spine.
"Sebastian..." Ominis warned.
"I dare you to touch yourself and let Ominis listen," he said louder. He slowly reached for your dominant hand and trailed it closer to your soaking panties. You wanted this — you just hadn't realized it until this moment. You let Sebastian guide your fingers under your underwear where he left you to your own devices.
"Come on, baby, don't be shy," he cooed.
Your fingers moved before your mind could tell them to, drawing slow circles across your clit. You moaned out in pleasure, lulling your head back against Sebastian's shoulders, but his eyes were focused on his friend from across the room.
Ominis looked like he was about to combust on the spot, his nails were digging roughly into the rug below him. His knuckles were turning white from the pressure and though he couldn't see, he still kept his head down, shyly.
"Put them inside of you," Sebastian breathed and you listened.
"F-fuck," you moaned as you plunged two digits inside, pumping them in and out of you.
"Say his name," he said even quieter.
"O-Ominis..." you whimpered and now he looked up, pinked cheeked, and ears perked. "Omi..." you cried out again.
No more dares, no more truths.
Ominis surprised you next as he crawled towards you, wand in hand brushing against the rug. When he was close enough to kiss, you used your free hand to pull him closer, crashing his lips onto yours. They had still been a little swollen from your previous kiss, but he came at you with his mouth slightly agape, ready for your tongue to overtake his again.
Lost in the kiss, you pulled your other hand from your core and used it to pull Ominis even closer to you, but Sebastian didn't let you go for long. You felt his hand reach where your hand had just been, circling your clit in only the way he knew how. You moaned deeply into the kiss, egging Ominis on. His hands found your face as your kiss became more passionate.
But then you felt two fingers insert you and Sebastian's thumb rubbed simultaneously against your nub. "S-shit..." you cried, pulling away for a moment to catch your breath. Ominis used to opportunity to grab your dominant hand, his face straight on yours with his ocean blue eyes darkening with lust. You watched him take your two fingers and press gentle kisses up and down your fingers, starting with the tips and ending with your palm. He licked so softly and sweetly against the plane of your hand before taking your two fingers into his mouth.
Your head lulled back again against Sebastian's shoulder as Ominis started sucking your juices off of your middle and ring finger. You felt every ridge of his tongue as it swirled against your skin.
You felt yourself getting close to your release, the coiling winding up in your belly. Between your boyfriend fingering you and your best friend with your fingers in his mouth, you were spiraling right towards an orgasm.
"I-I'm close," you whimpered out, feeling your release headed straight for you.
"Come for us, baby," Sebastian said, continuing to pump in and out of you.
You cried out in pleasure as the spring in your belly unwound, crashing down and releasing all over Sebastian's fingers. Ominis let go of yours with a quiet pop.
Your chest heaved up and down as you came down from your orgasm, trying to relax, but all you could notice was the two bulges surrounding you, Ominis in front of you and Sebastian below you.
"You could join us, Omi," you offered.
"Come on, it'll be fun," Sebastian added.
He led you over to his bed on the right side of the room, messy comforter lying undone. He laid down first and pulled you on top of him, straddling his lap. Ominis walked over, still acting shy despite the bold move he had done a mere five minutes ago. You grabbed him by the tie sitting sloppily on his white button up, dragging him down for another quick kiss, tasting your sweetness on his lips. "Don't go all shy on me now..." you said.
At the same time, Sebastian was undoing your top and skirt, discarding them to the floor and leaving your bare in front of them. Button by button, you undid Ominis' top. His pale chest was peppered with moles, like the ones on his face. You placed a kiss on a particular one on the left side of his chest, right over his heart where you felt the pounding.
After, you leaned down to undo Sebastian's shirt. His chest was all too familiar and still so beautiful. His chest was a galaxy of freckles you could get lost in if you let yourself. You laid your bare self on top of him, nipples brushing lightly over his broad chest, making them turn into stiffened peaks. Your hands traveled into his chocolate brown strands, pulling at the roots. He groaned, throwing his head back into his plush green pillows.
You used the opportunity to slide down his body and undo his belt, letting his cock spring free. Every time, his size still took your breath away. His freckles not only painted his face and chest, but here too. He was long and girthy, with a flesh toned tip.
You hadn't forgotten about Ominis either, standing there at the edge of the bed with his trousers still on. Leaning over, you undid his belt too, allowing is erection to be free. His was long and veiny, pale with a soft pink tip and a mole right at the base. "Ominis," you gasped.
"Do you want us both?" Sebastian asked now.
"I want you both inside of me. Please," you begged.
Sebastian directed Ominis on where to stand at the edge of the bed, explaining he would insert himself first. You lined up Sebastian's cock with your entrance, rolling his tip around a few times to slick the tip with your arousal before slowly sinking down onto his lap.
Every time felt like the first time as you adjusted to his size. His hands found your waist and guided you up and down a few times to let yourself become acclimated.
Next thing you knew, Sebastian was holding your body to his. He was holding you closely, hand already tangling in your hair to hold you lovingly, petting your head softly as Ominis lined himself up with your rear entrance. He spit into his hand, running it over his cock, slicking it before easing into you.
"Shh, baby, it's okay," Sebastian cooed, still playing with your hair.
The stretch in that area was not something you were used to, but quickly the pain had turned into pleasure. You felt Ominis' hips reach your backside, letting yourself know he was all the way in.
"You're such a good girl," Sebastian breathed as he continued to hold you.
They found a steady rhythm with both of them taking turns pumping in and out of you, leaving you in constant pleasure. You were a moaning mess between the two men as they filled you with euphoria.
The whimpers coming from behind you were nearly enough to make you come on the spot again. Ominis surely hadn't had sex if he had never kissed anyone before, you knew he wouldn't last long. You used your core muscles to pull yourself away from the comfort of Sebastian's arms to lean back up against Ominis' chest.
You felt his heavy breathing rising and falling in fast motions against your back as you leaned a hand back to steady him. "You're doing so good too, Omi, you feel so good," you reassured him. You held his blonde hair in between your fingers, not tugging, just soothing. You darted your eyes down to the brown ones beneath you and he watched you lovingly as you took care of his best friend. His hands held tightly to your waist, where his thumb found its way to your clit again.
Your head leaned further back into his shoulder. "Hold her still Ominis," Sebastian said.
Ominis' hands wound themselves around your chest and frontside, holding you still as they both continued fucking you, but you felt both of them falter once, thrusts becoming sloppy.
"Shit, baby, I'm close," Sebastian muttered out of breath.
You felt it coming too as he toyed with your core.
The three of you all shattered at the same time. You felt both of your holes become filled with warm release, filling you to the brim, leaking out in drips across the clean sheets.
Your body was buzzing as you came down from your high, feeling like you were floating.
You leaned back once to press a soft kiss to Ominis' lips before he pulled out, stumbling backwards. And then you leaned forward to kiss Sebastian in an all-consuming kiss. "I love you," you whispered.
"I love you, too," he cooed, putting a strand of your hair behind your ear where it had fallen out of place.
The two of you collapsed onto the bed in a mess of heaving chests. You saw Ominis start to walk towards his own bed across the room. "You could stay over here too, you know," you said.
The Ominis you thought you knew would've died if he knew he was about to share a bed with Sebastian Sallow, but he had done a lot of things that night he had not been prepared for in the slightest.
You lay in between the two of them, Sebastian nuzzling close to your cheek and Ominis with his head aross your chest. You fell asleep like that, cuddling your two most favorite people in the world. You weren't sure what the next day would bring, but for the time being, you were content.
