Chapter Text
There was nothing that hyped up Min Yoongi more than a successful performance with his BTS band mates. The roar of the crowd, the lights, the thrum of the music as it raced through his veins, turning into adrenaline that pumped him up even more. Yes, there was nothing that hyped Yoongi up quite like that did.
Well, almost nothing.
There are three sides to Min Yoongi. Suga, which is his stage name, and the serious, beat-driven, focused persona he adopts while onstage. There's Yoongi, which is his more relaxed, gummy-smiling, sometimes salty, yet caring offstage self. And then... there is Agust D. Agust D is more passionate, more savage, more raw, more real, more open, more focused, more in-your-face than most people can handle in more than small doses at a time. It's comparatively rare that Yoongi gets to show that third side of himself. That's why when he does, it pumps him more than a BTS performance. As in, it literally 'pumps him up', because even he knows that he exudes raw, unadulterated sexuality when he's performing as Agust D.
Yoongi and the other BTS members had been preparing for their ARMY 3rd Muster, and Yoongi has been rehearsing for his performance of Tony Montana, with a special appearance and verse by Jimin. In the midst of rehearsals, Yoongi knows Jimin is holding back a bit, which should worry Yoongi but it doesn't. He's known Jimin long enough that he knows the younger is saving his whole energy for the performance.
Little does Yoongi know that that isn't all Jimin is saving.
Yoongi has had some pretty damn strong feelings for Jimin for a few years now. It started with Jimin first took on a raspy, gravelly quality to his voice during one of their concerts. It had made Yoongi want to fuck Jimin into next week, but he hadn't, for the simple fact that he didn't want to take advantage of his dongsaeng. Instead, he'd spent countless nights dreaming about it while jacking off when he was too painfully hard to keep himself from sneaking into Jimin, Hoseok, and Taehyung's shared bedroom. He felt like a horny, desperate teenager again, and he hated it.
The day of the 3rd Muster has finally come. Everything goes smoothly. The fans are kind and respectful (and of course generous with their cheers, chants, and screams), there are no technical difficulties or accidents, and the members' vocals and choreography are, as always, perfectly on point. Yoongi takes his position onstage, ready to slay as Agust D. The music starts, the crowd cheers, and Yoongi feels adrenaline coursing through his veins before he even starts rapping. He knows that he is absolutely owning that stage. Every step, every gesture, every word spoken into his microphone is done with an unrivaled swagger and has the audience stunned into silence.
Until Jimin comes out.
Yoongi is already feeling fired up. The blood rushing through his veins and straight to his hardening dick already has him already thinking about going home and jacking off, taking no mercy on his fist, or his erection, just like he would have no fucking mercy on Jimin's ass. Until Jimin comes out though, Yoongi has everything under control. But then the younger starts rapping. Yoongi almost falters hearing him growl into his microphone, using his Busan dialect to make all the girls in the audience scream so loudly it's a miracle the glass doesn't shatter. He almost forgets the ad libs he'd added – to his own damn song, God what is this boy doing to him? - but thankfully he gets his shit together and is able to finish the performance with no slip-ups. But damn... Yoongi feels his erection pressing painfully against the rough fabric of his jeans (Why hadn't he worn boxers??) and knows that he can't and won't hold back from fucking Jimin anymore. That is, if the boy wants it. He has to make sure.
The second they've finished with everything for the day, Yoongi pulls Jimin aside. "Hey, Jiminie, can I talk to you for a second?" The younger nods and lets himself be walked to one of the abandoned dressing rooms. Yoongi closes the door, thinking their conversation would be better done in private. Taking a deep breath, suddenly nervous, he murmurs, "I have a small problem I need you to help me with."
"What kind of problem, hyung?" Jimin's eyes are wide. Yoongi steps closer to him, gently grips one of his hands, rubbing slow circles on his palm using his thumb, and stops until his lips are inches from Jimin's. "H-hyung?" Jimin's voice catches in his throat.
"Jimin-ah, if you don't want to do this you can tell me, but..." his voice trails off as he places Jimin's hand over his bulge, letting the action speak for itself. He patiently waits to see what Jimin will do, but he has to bite his lip to contain a soft gasp. Jimin gulps and removes the hat and sunglasses he's still wearing before he walks far enough away to lock the door, and then he comes back to gently sink to his knees in front of the elder.
"I would be glad to help my hyung,"he murmurs, and Yoongi can't believe his ears or his eyes as Jimin starts unzipping his jeans, causing Yoongi's erection to spring free, and the older gasps at the sensitivity.
"Jimin, p-please..." he moans softly, and Jimin smirks devilishly up at him as he licks a fat stripe up the underside of Yoongi's shaft. Yoongi's body goes rigid at the contact and he lightly caresses his dongsaeng's hair. Jimin takes the head of Yoongi's cock into his mouth and sucks gently, his tongue digging into the slit as his small hand wraps around the shaft and strokes slowly. "Jiminie don't tease me baby boy." The name tumbles out of Yoongi's mouth before he can stop it, and before he can apologize, he hears a barely audible groan come from the younger boy. Both freeze for a second, and Jimin suddenly hollows out his cheeks and sucks hard until he takes Yoongi whole, letting the head slip past his throat and drawing a long, loud moan from the elder.
"Fuck Jiminie your mouth is amazing," he murmurs as he fists his hands in the younger's blonde locks. Jimin looks up at him and smiles around Yoongi's dick before he starts slowly bobbing his head back and forth, his movements a bit unsure at first, but Yoongi grips his hair tighter and bucks his hips slowly, groaning "You're doing so good baby boy. Just like that. Make Daddy feel good." Yoongi's eyes are closed in ecstasy, so he doesn't see the deep red color Jimin's face and ears have turned. The younger draws his head all the way back and teasingly gives Yoongi's cock kitten licks as he strokes his shaft, taking a deep breath before he speaks.
"I want to make Daddy feel really good." Yoongi moans more loudly at the words and barely gives Jimin a chance to get his cock back in his mouth before he tightens his grip on the younger's hair and starts fucking his throat. Jimin helps him along by stroking the base of his shaft with one hand and massaging his balls with the other, moaning just to send vibrations through the older's cock and up his spine. It amazes Yoongi that Jimin seems to have no gag reflex.
"Jimin, baby, I'm so close," Yoongi pants, and he lets go of Jimin's hair. "Where do you want me to cum?" Instead of answering, Jimin slowly draws his head back and wraps his plump lips around the head, gripping his shaft as hard as he can and moving his fist at a breakneck speed. "FUCK!" Yoongi growls as cum spurts from the tip of his cock and lands on Jimin's tongue, moaning as he bucks his hips gently and watches the younger swallow down every drop. Yoongi pants heavily as he all but yanks the younger to his feet and crashes his lips against his in a passionate kiss, his tongue immediately delving into Jimin's mouth and easily dominating the kiss. Jimin's lips feel so good, something Yoongi could get addicted to if he's not careful. He moans into the younger's mouth, reaching between the two so he can palm Jimin through his pants, until there's a jarring knock on the door, causing the two of them to jump apart.
"Yah! You've been in there for almost an hour, and everyone is waiting to go home. Come on." Namjoon's voice sounds tired but still holds all the authority of a leader.
"Coming hyung!" Jimin sings out, and he picks up his discarded hat and sunglasses as Yoongi fixes his jeans. Before they leave the room, Yoongi leans in close and whispers a single sentence that holds so much dark promise.
"When we get home, that ass is mine."
