The apartment was dark, every light switched off.. The cake sat proudly on the table along with Yoongi's favorite snacks. Decorations were hanging slightly crooked but Jin argued that it's the latest trend.
Five grown men crouched awkwardly behind the couch and kitchen counters.
“Ssshhh!” Namjoon hissed, pushing Jungkook’s head lower. “They’ll see you if you stand up.”
“I still think this was a mistake,” Seokjin whispered, fanning himself nervously.
“If Jimin finds out, he’ll ruin the surprise.”
“That’s why we didn’t tell him,” Hoseok grinned. “No spoilers if he doesn’t even know.”
Taehyung giggled. “This is gonna be so good.”
The front door lock clicked. Everyone stilled, breath held. Keys jingled.
Namjoon mouthed, “One… tw—”
A thud.
Then Jimin’s voice, breathless and needy: “Hyung!”
The group froze.
Jimin's POV
Yoongi didn’t give him a chance to breathe before his mouth was on him, hot and desperate. Jimin’s back slammed against the door, the lock barely catching before Yoongi claimed his lips in a rough, messy kiss.
“Hyung!” Jimin gasped, pulling in air between kisses. "Someone—"
“I don’t give a fuck,” Yoongi growled, his hands already pushing under Jimin’s shirt, tugging at his waistband. “Been hard since the second you bent over in the car.”
The blunt honesty made Jimin flush. The thrill of it sent him spiraling. His knees hit the floor before he could even think twice.
He tugged at Yoongi’s zipper, freeing him, and the weight of Yoongi’s cock against his lips made his stomach clench in excitement.
Yoongi groaned when Jimin licked the tip, hot and teasing. “Don’t tease me, baby. Get your pretty mouth on it.”
That voice, rough with need, undid him. Jimin opened wide and swallowed him down, messy and wet, his throat stretching as Yoongi’s hand tangled in his hair.
Other's POV
The sound echoed down the hall. Not footsteps. Not laughter. Slurp.
Every single one of them stiffened like statues.
“Oh my god,” Seokjin mouthed, slapping a hand over his mouth.
Hoseok choked, biting down on a throw pillow, eyes bugging out as he tried to hold in laughter.
Namjoon’s face drained of color. “Please no. Not here. Not now.”
Yoongi’s groan cut through the silence, deep and broken: “Yeah, that’s it. fuck! you’re so good with your mouth.”
Taehyung squealed softly, covering Jungkook’s ears with both hands. “Don’t listen! Protect your innocence!”
Jungkook wriggled free, whispering furiously, “I’m not a baby, hyung! But holy shit! it’s so loud!”
Another wet, obscene slurp. Jimin’s muffled moan vibrated through the walls.
Yoongi gasped again, voice cracking: “Messy, baby drool all over it. Love it when you’re filthy for me.”
Hoseok collapsed sideways, silently wheezing into the carpet. Seokjin smacked him in horror. Namjoon muttered a prayer into his palms.
And still, the sounds kept coming.
Jimin's POV
Yoongi’s cock filled his mouth, heavy and hot. Jimin moaned around him, spit spilling past his lips, dripping down his chin. His hands worked Yoongi’s thighs, feeling them tremble under the strain.
“God, baby, you’re too good at this,” Yoongi panted, head hitting back against the door. His hips jerked, shallow thrusts feeding himself deeper into Jimin’s throat. “Fuck! you swallow me so well.”
Jimin hummed, loving the way Yoongi’s breath caught. He pulled back just enough to lick around the tip before taking him deep again, gagging lightly on purpose just to hear that guttural groan.
“Shit—don’t stop,” Yoongi begged, voice breaking. His fingers tightened in Jimin’s hair. “I’m so close. Gonna come down your throat, baby. Want you to swallow it all.”
Jimin’s stomach twisted at the raw need in his voice. He bobbed faster, sloppy and wet, his own cock straining in his jeans. He wanted Yoongi to lose control, to come undone just for him.
It worked. With a choked cry, Yoongi spilled into his throat, hot and thick. Jimin swallowed greedily, sucking him through it, licking his lips when he finally pulled back.
“Happy birthday, hyung,” he whispered, smug and breathless.
Other's POV
The five of them sat frozen in the dark, traumatized witnesses to every single detail. The final wet gulp echoed through the hallway.
“Okay,” Seokjin whispered frantically, flapping his hands. “We cannot just sit here after that.”
Namjoon rubbed his temples. “We pretend. We light the candles, we sing, we—”
Yoongi’s hoarse voice interrupted, satisfied and rough: “Thank you baby. You're such a good boy. Swallowed everything hyung gave. ”
That was it. Jungkook burst into stifled giggles, Hoseok fell flat on his back howling silently, Taehyung squeaked, and Seokjin, high on stress, snapped.
“SURPRISE!” he screamed at the top of his lungs.
The lights flicked on.
Yoongi froze against the wall, pants half-zipped. Jimin whipped his head around, still kneeling, lips swollen and wet.
The group erupted:
Taehyung shrieked into his hands.
Jungkook dropped his phone, but not before catching the most incriminating blurry photo imaginable.
Hoseok was rolling on the floor, wheezing with laughter.
Namjoon muttered, “I hate my life.”
Seokjin screamed, “ZIP YOUR PANTS FIRST!”
Yoongi groaned, dragging his hand down his face. “Happy fucking birthday to me.”
Jimin scrambled up, mortified, stammering, “I-I can explain—”
Namjoon cut him off instantly. “For the love of god, don’t.”
The cake sat untouched on the table, candles still unlit, while the worst surprise party in history unfolded in front of them.
