“ Shhh ,” whispered Jimin against Jungkook’s ear, pressing a calloused hand against his parted mouth. “You have to keep quiet, baby. We don’t want your brother to see you like this, uh?”
Junngkook’s eyes rolled back as he moaned. Jimin hissed and pressed his hand harder against his mouth but didn’t stop thrusting, the wet squelch of his cock fucking into Jungkook’s ass loudly echoing in the silence of the house. Jungkook clenched around him every time he bottomed out, his body desperate to keep him inside. He wanted Jimin buried so deep he could feel him for the rest of their vacations. The idea of sitting for breakfast in front of his unaware brother when his brother’s best friend had fucked Jungkook into his childhood mattress was… fuck.
Jimin’s teeth dug into the tendon of Jungkook’s neck to keep himself from making noises. Jungkook was whimpering, soft ah-ah-ah falling from his lips and dripping through Jimin’s fingers. He had not stopped whimpering since Jimin had tip-toed his way down the hallway and slipped into Jungkook’s room under the cover of the night half an hour ago.
The house was empty except for the three of them. The rest of his family would be arriving in the morning and Jungkook knew that was the main reason why Jimin’s resolve had finally given in after a week of Jungkook flirting with him and parading around the house in increasingly skimpy shorts. It wasn’t going to be that easy to sneak past Jungkook’s parents to fuck their son. Jungkook almost wanted to complain about all the time they’d wasted this week but it was extremely hard to stay mad at him when he was holding one of Jungkook’s legs in the air so he could spoon-fuck him better.
Yoongi had always known about Jungkook’s little childhood crush on his best friend and it had always amused him. Things hadn’t changed as they grew older; the ten years separating them in age was a chasm Jungkook had always resented. Reasonably, Jimin had never given him a second glance, not even after Jungkook turned twenty-three and his “second puberty”, as Yoongi liked to joke, had hit him like a truck.
That had changed about a year ago. Jungkook had yet to figure out what had shifted, but last summer all the fantasies that had made a teenage Jungkook cling to the sheets of his bed with white knuckles had come true. One day, Jimin had turned around and noticed the twenty-six-year-old man his best friend’s younger brother had become and, well. The rest was history.
Neither of them was ready to tell Yoongi.
Jimin slipped his cock out enough time to grab Jungkook by the waist and turn him around, pressing his chest to the mattress and his face to the pillow, muffling Jungkook’s strained moans. The equal part domination and restriction of breath made Jungkook dizzy with arousal, even if Jimin only did it because Yoongi’s room was right next to Jungkook’s. They both enjoyed how muffled Jungkook’s sobbing moans sounded, though, and Jimin made it known with the guttural groan he let out, brows furrowing together, eyes barely managing to stay open as he pushed his cock back into Jungkook.
The soreness at the result of being fingered too quickly and sloppy made Jungkook more sensitive than ever and his assaulted prostate took each thrust from Jimin like a gut punch. Jungkook choked and sobbed, gripping the headboard with one hand and fisting himself furiously with the other, desperate for release. He was so close he could taste his climax at the back of his throat and just when he thought he might be closing on an orgasm, Jimin snarled down at him, “Don’t you dare cum.”
Jungkook clamped down on himself obediently, his hiccups muffled by the pillow. Pain and pleasure flooded his body and he struggled with the mixed sensations, wanting to pull away and push back. Jimin didn’t stuttered. He tightened his grip on Jungkook’s hips, his thumbs pressing down against Jungkook’s lower back as he kept fucking him through the mattress.
Jungkook tried to prop himself on his elbows to regain a little autonomy but he was being manhandled again before he could succeed. Jimin turned him around roughly, one knee propped on the bed and the other one on the bedroom floor. He spread Jungkook’s asscheeks and spat right into his hole before pushing his cock back in.
Jimin was quick to clamp a hand over his mouth and still Jungkook had to bite the insides of his cheek until he tasted blood to prevent himself from moaning like a whore. Fucking older men was going to kill him.
Jungkook watched Jimin pound into him through bleary eyes. Sweat beaded on Jimin’s bare chest and dampened his brow, turning his ruffled bangs to thick tendrils until he hastily swept them away. Seeing how worked up Jimin was ignited something hot and sticky in the pit of his gut, and if Jungkook had more of his head, and if he was allowed to use his voice, he might praise the older man, tell him how good he looked above him, how good his cock felt inside.
Jimin released Jungkook’s mouth in favour of hooking his thighs over his elbows, pulling Jungkook’s ass off the mattress a bit. It allowed Jimin to thrust even deeper and the added force behind them with the better angle made Jungkook pull one hand up to take Jimin’s place so he could release his pleasure in the form of desperate moans and wild panting. Jimin’s forehead fell on Jungkook’s chest; the sweaty feel of their skin-on-skin contact was too warm, too messy, too much.
“Fu-fuck,” Jungkook wailed into his fingers, trying his best to keep his voice low. He flipped his hand over to bite his knuckles and tried flexing the muscles deep inside him again to keep his orgasm at bay. “ Hyung. Hyung, please. Please. Can I cum? Can I?”
Jungkook saw the way Jimin worked his jaw before nodding just once. Jungkook curled in on himself as his orgasm finally uncoiled, his hole clenching around Jimin’s energetic thrusts. It felt like the harsh snap of a rubber band after a long week of being pent up. Jimin watched with a small, smug smirk as thick ropes of cum coated Jungkook’s abs and chest, his hips not faltering even after Jungkook fell back into the mattress limp and exhausted, his cock spasming feebly.
Jimin’s eyes glinted with mischief as he wrapped a hand around Jungkook's cock experimentally. Jungkook whimpered in protest, grabbing Jimin’s wrist weakly but didn’t push him away. It was too much too soon. Too much feeling, too much everything, and Jimin hadn’t even slowed down, fucking him with powerful bucks of his hips.
Every sensation was amped up to the extreme. He should have been going soft after that severe orgasm but somehow his cock was responding to Jimin’s touch as he jerked Jungkook back to full hardness without giving him a break.
“Come here,” Jimin grunted after he was satisfied with Jungkook’s aching dick and grabbed him by the back of the neck to pull them together in a brutal kiss. Sweetly, he hummed in Jungkook’s mouth, “You can keep going now.”
Jungkook whined and nodded obediently, letting Jimin lower him down on the pillow again before bracing the back of his knees and pushing his legs as far over as he could, bending him in half. Jungkook’s arm fell over his eyes as he clenched his teeth and bared Jimin’s wildly rolling hips.
Jungkook’s abused prostate made him feel every drag of Jimin’s cock inside him with absurd intensity, and he found himself battling a second orgasm in what felt like no time at all, clasping his lower muscles in the only attempt of buying more time he could manage right now. Jimin’s breath hitched, the first sign that Jungkook clenching around him was affecting him, and his hips stuttered. He hissed a warning at Jungkook but didn’t stop him from riding the edge of his orgasm.
“Hy-hyung. Hyung, I’m gonna cum, gonna cum, gonna c-c-cum,” he didn’t realize he was babbling out loud again, loud enough to skirt into dangerous territory but Jimin was too busy holding him in place to bother to shut him up.
Jungkook pressed his palm against the flushed head of his cock and the pull was immediate. He struggled to breathe, feeling his entire lower half pulse with his orgasm, his toes cramping as they tried to curl in on themselves. Jimin’s hips stilled for a moment, the sound of his laboured breath echoing loudly, and waited for Jungkook to come down from his high, dripping weakly on his stomach again, barely letting out anything. When Jungkook finally peeled his eyes open, Jimin’s expression was dark.
“I’m going to move again,” he warned. Jungkook nodded, too fucked-up to think twice about it. Jimin adjusted his position, planting his foot on the bed at Jungkook’s side. In no time, he had one hand pressing down on Jungkook’s chest near his throat, fucking down into him with the added leverage that made them both groan at the same time.
“Cum for me?” Jungkook urged gently, brain a dizzy tangle of desire. He wrapped a hand around Jimin’s wrist and hooked the other behind his knee, opening himself up. “Cum for me, hyung? Fill me up?”
Jimin snarled at him but didn’t slow, sweat dripping down his spine.
“Fuck,” was the only thing he said, sinking his fingers in the meat of Jungkook’s ass, fucking down into him desperately. “ Shut up .”
Jungkook ignored him. Who cared? Who fucking cared if he was too loud? Who cared if Yoongi got mad at them? Nothing mattered. He was drunk on the smell of Jimin’s sweat, and the feeling of Jimin’s skin slapping against his. He was too overwhelmed to think about future consequences. They didn’t matter. Not when he got Jimin right where he had always wanted him. He reached up to run his fingers through Jimin’s hair, pressing kisses into his throat and up his ear.
“Please cum for me, h-hyung… You’re so big, you fuck me so good.” Jimin’s hips stutter, rutting him against Jungkook’s prostate sweetly, eliciting a breathy moan from Jungkook. “’S perfect… Lo-love being filled b-by hyung’s cock. Wanna drip hyung’s c-cum so bad.”
Jimin gasped. His hips snapped forward to bury inside Jungkook and his face mashed hard into his chest, groaning low and pretty between his pecs. Jungkook felt every inch of Jimin’s cock inside him throbbing as he emptied himself deep. His eyes were clenched tight, his breath short and laboured, and each spurt had his hips twitching further into Jungkook, making him hiss.
His third orgasm took Jungkook by surprise. He tumbled into it right after Jimin, the pleasure feeling razor-sharp and sore . He sobs through it, amazed that he was capable of coming dry. Fuck. That was a discovery.
It took forever for either of them to come down. Jimin recovered first, easing his softening cock out to roll over onto his back, his chest rising and falling as if he was still running a marathon. Jungkook turned his head to look at him with a shit-eating grin.
“You’re too fucking loud,” growled Jimin. He pushed apart Jungkook’s legs, spreading one of his cheeks to the side and letting out a curse at the sight of his cum dripping down Jungkook’s asshole. “God. Yoongi is going to fucking kill me.”
