Chapter Text
Notes:
I really really wanted to see some Sukuitafushi in an established relationship since I haven’t seen anything like this here on ao3 yet (correct me if I‘m wrong plsss :D) and since I really was starving for that I just wrote it myself so purely self-indulgence here xD
Also, I was a bit inspired by this amazing fic by rosexwald which I read a few years back and now came back to because I never wrote an established relationship with three people involved and this fic is so brilliantly written ♡
And since Sukufushi AUs are my life ofc I had to write in an AU outside the jjk universe without the angst and all that and I just loveee the idea of Sukuita as twin brothers such a nice flavor. Anyway, enough talk from me I hope you enjoy reading as much as I did writing ♡
It all began when Yuuji started going out with Megumi. They meet in college, attending the same class. Somehow, they also ended up at the same college party and at the end of the night shared their half drunken first kiss. After that they went on many dates, exchanging innocent and not so innocent kisses. Yuuji was an attentive lover, always so sweet and caring and he always seemed to know what Megumi needed. And Megumi loved the sweet affection he was given. So, when Yuuji asked him to be his boyfriend Megumi didn’t need time to think it over and accepted immediately.
In Megumi’s eyes it would all have been perfect if it weren’t for Yuujis twin brother, Sukuna. And Sukuna seemed to be frequently in Yuuji’s flat whenever Megumi and Yuuji were there. It was not that Sukuna bothered the two of them. It was just that Megumi found himself distracted. Megumi loved Yuji with all his heart but he also couldn’t deny the unbearable pull he felt towards Sukuna whenever the other was there.
Maybe because they were so similar regarding looks, although Sukuna had several tattoos adorning his face and body as well as some very distracting piercings. Either way, Megumi found him insanely attractive just like he found Yuuji attractive. Nevertheless, Megumi never meet twins with such completely different personalities. While Yuuji was cheerful, gentle and caring, Sukuna seemed to be the complete opposite, like some kind of evil twin - at least that was what he looked like to Megumi at some times.
Still, he couldn’t deny his attraction and sometimes he had the dark premonition that Sukuna also knew. For example, when Megumi’s eyes lingered a bit too long and Sukuna caught him staring at him. On the other hand, he could swear that he felt Sukuna’s eyes on him a few times as well.
Looking back, Megumi could have known. He really could have known that one thing will lead to another eventually when one evening Yuuji wasn’t home and Sukuna dropped by unexpectedly. Megumi didn’t know how it exactly happened. One moment he was talking with Sukuna in the kitchen, the next he was sitting on the kitchen counter with Sukuna between his legs, kissing him breathless. From there on it wasn’t far to the bed where they landed eventually.
Megumi was devastated afterwards, feeling horrible at the thought of facing yuuji after he slept with his twin. On the other hand, he shivered at the memory of the night he spent with Sukuna, butterflies pooling in his stomach. Sukuna was like a storm, kissing him passionately, handling him roughly but at the same time whispering soft praises in his ear and it made Megumi crazy - he loved every second of it.
Overall was his first impression of Yuuji’s twin almost entirely wrong. While Sukuna looked kinda scary and acted cold and uncaring, he was actually very caring - at least towards Megumi. But this made Megumi’s situation all the more difficult.
Eventually he could not live with the guilt. Yuuji was such a sweet and caring boyfriend who always gave Megumi everything and Megumi knew that Yuuji loved him and he also loved him back.
He told him everything. Told him that he loved him but also couldn’t get his twin brother out of his head. He had never been in a situation like this and Yuuji neither. They decided to give each other space for a while.
It was Sukuna who ultimately gave a possible solution to the situation when he sat down with his twin brother one evening to talk things out. Although Sukuna was very possessive in his nature, he suggested that Megumi did not have to choose between them and that he didn’t want to see him suffer to which Yuuji agreed. In the end they agreed that as long as Megumi was happy things would turn out alright.
When the twins presented their suggestion to Megumi, that he could have both of them, that he didn’t had to choose, he was reluctant at first, unbelieving that things would actually turn out like this. After thinking everything over he agreed to try it out and so they started their unusual relationship.
At first, it was very new to Megumi - as it also was to the twins- but surprisingly they lived together so naturally, almost like before he slept with Sukuna, except now he didn’t had to hide his feelings anymore.
He was free.
And after a while Megumi had to confess he loved living with both of them. Loved getting double the attention, double the affection and double the devotion. And Megumi finally realized that he could give double the love. And they loved him back so all-encompassing he sometimes felt like he drowned in it.
Just like he did now, laying sandwiched between them, both still sleeping soundly, Megumi’s back pressed to Sukuna’s strong chest, his arms encircling Megumi’s slender waist while Megumi’s hand was loosely intertwined with Yuuji’s slightly larger one, his face tugged into Yuujis neck. Yuji’s skin smelled really delicious, sweet like vanilla but not intrusive. It was a stark contrast to Sukuna’s scent, which somehow reminded Megumi of burned sage. It calmed him immediately. He loved it. Both of their scents together however were intoxicating.
It was still fairly early, morning light filtering through the curtains, bathing their bedroom in a warm, soft light. Megumi cursed his inner clock that demanded to wake up early and go to work, although it was a Sunday and he had nowhere to go. He contemplated if he would manage to go back to sleep since he was a really light sleeper.
Minutes passed and he huffed against Yuuji’s neck, fidgeting a little in Sukuna’s grasp.
"Can’t go back to sleep darling?" a husky voice whispered from behind him, as two arms tightened around him.
"Mhmm," Megumi murmured. He managed to turn on his back slowly, facing Sukuna, Sukuna’s arms not letting him go from his embrace.
Megumi’s one hand still remained intertwined with Yuuji’s, squeezing it lightly while his other hand softly carded through the soft hair of Sukuna’s undercut. they shared a lazy soft kiss, Megumi humming against Sukuna’s warm lips contently.
in the quiet room they exchanged soft whispered words, only for them to hear. the sun rose slowly, warming their skin, their lips touching occasionally.
After a while Yuuji also stirred, burying his head in the crock of Megumi’s neck, his fingertips grazing over Megumi’s stomach lightly.
Megumi smiled, "Mhmmm mornin’" he cooed, carding his hand through Yuujis unruly hair. Yuuji groaned softly against his neck, before raising his head to meet Megumi’s lips.
They shared a tender kiss while Sukuna’s hand joined Yuuji’s under Megumi’s shirt, brushing against his nipples lightly and Megumi hummed against Yuuji’s lips, sucking on his bottom lip. He arched into the touch, already craving more of their warm hands on his skin.
He was still deliciously sore from last night, where both had him at the same time. Remembering how good he had felt with both inside him, rubbing him in all the right ways, made Megumi shiver. It was his favorite position for them. This way they all felt the same sensations and he didn’t had to choose between them. Biting his bottom lip, his hungry gaze met Sukuna’s.
Sukuna’s scarlet eyes were fixated on how his teeth tugged on is lips, "what are you thinking about precious?"
"Just..remembering last night," he revealed "you were both so good to me." Sighing, he carded his fingers through Sukuna’s locks.
"Mhmm we love you," Yuuji murmured against his neck and sucked on Megumi’s pulse point, adding a love bite to the collection already adorning Megumi’s neck.
The sensations they felt the night before still tingled in their bones and despite having their fill of one another it seemed like it would never be enough. After a night like this, were his twins made love to him so thoroughly, Megumi found himself crave them even more.
"I love you too - so, so much," he breathed against Sukuna’s mouth, pressing his lips to Sukuna’s yearningly before pulling Yuuji up to share an equally passionate kiss with him.
Like this they took turns tasting Megumi’s plush lips. And Megumi hummed softly against their lips, savoring their taste. It was like tasting two completely different flavors and finding out that both were very delicious.
His shirt disappeared at some point as well as his boxers. Sukuna palmed one of his nipples lightly while Yuuji’s hand stroked his already leaking cock head on, smearing some pre-come to aid his movements. Megumi bucked his hips into Yuuji’s palm, needing more of the delicious friction Yuuji’s warm hand provided, moaning against Sukuna’s lips.
Despite his haze of lust, Megumi managed to sneak his hands beneath the large blanket they shared to palm their erections through their boxers, eventually slipping past the cloth to stroke their hot flesh head on, earning content groans. Megumi just loved pleasing his twins. He loved how they felt in his hands, so similar and yet so different. Aside from having them both inside him he also enjoyed being used by them, loving when he got to suck one of them off while the other fucked him roughly from behind, the thought alone being enough to wreck a shiver through him.
Just when he pondered the idea to bring them pleasure like this, Sukuna spoke against his lips, his fingers holding his chin.
"Sweetheart, turn around," he ordered with his raspy voice.
Megumi gave him one last hungry kiss. He tasted Sukuna’s tongue, feeling the metal bead of his piercing, which he loved, before complying eagerly, meeting Yuuji’s plush lips in a tender, wet kiss as he did.
Megumi tucked on Yuuji’s boxers eagerly, only huffing an "off" against Yuuji’s lips, desperate to feel Yuuji’s erection against his. Thankfully he didn’t had to wait long and Yuuji slotted his hips against Megumi’s, aligning their already dripping cocks and stroking them with his large hand. At the direct contact Megumi let out a loud moan, which was almost immediately swallowed by Yuuji’s demanding lips.
Simultaneously, he felt Sukuna plant hot kisses against his nape as he pressed his erection against Megumi’s ass eagerly, rubbing against him. Megumi placed a hand on Sukuna’s strong tattooed thigh, wanting him closer while he bucked into Yuuji’s hand on instinct, breathing harder with every new stroke. Sukuna also picked up the pace, his hands holding Megumi’s hips in an iron grip as he found friction between his plush ass cheeks.
"Nghhh I‘m..not gonna last," Megumi confessed to them.
"Then cum baby," Yuuji breathed, giving their cocks a particularly delicious squeeze.
Megumi shuddered. throwing his head back with a silent scream he came, his body quivering. Yuuji felt his lovers cock pulse against his own and with a couple more strokes he came as well, coating his hand in their releases with a deep groan.
Sukuna wasn’t far off either. Megumi’s undoing seemingly enough to make him cum as well, he spilled his hot seed on Megumi’s lower back while he bit into his shoulder with a groan.
It took a while for them to come back from their shared high. Their minds still in a haze, wrapped up in each other completely.
Megumi was the first to come back to reality. He kissed Yuuji’s lips lazily, his eyes still half lidded before he turned his upper body slowly, his fingers finding their place in Sukuna’s ruffled hair again.
"Let’s take a bath?” he suggested as he pressed his forehead against Sukuna’s contently.
Sukuna hummed in agreement and Megumi turned to Yuuji who also seemed to like the idea. Thankfully they had a big bathtub where all three of them could fit.
As Megumi coaxed his twins out of the bed he couldn’t help feeling giddy, already looking forward to a wonderfully lazy Sunday with them. He was truly happy.
