The Mafia's Debt - J.JK × K.SJ✔

14

It was another day filled with laughter as Jin sat on the couch, watching Haru run around the living room, full of energy. Haru had taken a liking to calling Taehyung and Jimin “Dad” every time they came over, which always amused Jin to no end. Today was no different.

Jimin was lounging on the floor, scrolling through his phone, while Taehyung entertained Haru with silly antics. Haru giggled loudly, running into Taehyung’s arms and yelling, “Dad! Catch me, Dad!”

Jin chuckled, enjoying the lighthearted atmosphere, but he couldn't help noticing Jungkook's growing annoyance as he sat beside him, arms crossed and brows furrowed.

"Why is he calling them Dad?" Jungkook muttered, his voice low but laced with irritation. His eyes tracked Haru as he joyfully clung to Taehyung’s leg, still calling him “Dad” without a care in the world.

Jin leaned back, grinning as he teased, “Jealous much?”

Jungkook shot him a look, clearly unimpressed. “I’m not jealous. I just don’t get why he’s calling them that when I’m his real dad.”

Jin laughed, nudging Jungkook’s arm playfully. “Relax, he’s just a kid. He calls everyone he loves ‘Dad.’ It’s cute.”

“Cute? It’s confusing,” Jungkook grumbled, his possessive nature flaring up as he watched Haru laugh with Taehyung. “I’m his dad, not them.”

Jin smirked, finding Jungkook’s frustration oddly endearing. “You know he adores you, right? No need to get all worked up. He probably thinks it's fun to have so many ‘dads.’”

Jungkook huffed, clearly not convinced. “I’ll have to set him straight. One dad is enough.”

Before Jin could respond, Haru came running over, climbing into Jungkook’s lap, his little hands reaching up to grab Jungkook’s face. “Daddy! You’re my dad too!” Haru giggled, as if sensing Jungkook’s inner turmoil.

Jungkook’s expression softened immediately, his annoyance melting away as he ruffled Haru’s hair. “I better be your only dad,” he said with a half-smile, pulling Haru closer.

Jin watched the interaction, warmth spreading through his chest as he realized just how much Jungkook cared about his role in Haru’s life. No matter how possessive or overprotective Jungkook got, it was all rooted in love, and that made Jin’s heart swell.

Jimin, however, couldn’t resist chiming in from across the room. “Aww, don’t worry, Jungkook. Haru’s just expanding his dad collection.”

Taehyung chuckled in agreement. “Yeah, you can never have too many dads.”

Jungkook shot them both a glare. “Not helping, guys.”

Jin burst out laughing, shaking his head at the whole situation. This chaotic little family dynamic was everything he hadn’t known he wanted, and as Jungkook playfully scolded Haru for calling others “Dad,” Jin realized he wouldn’t trade it for the world.

As soon as Taehyung and Jimin left with Haru for their walk, Jungkook let out an exaggerated whine, his frustration still lingering from earlier. Jin, who was standing beside him, noticed and couldn't help but smirk. Feeling playful, he decided to tease Jungkook.

"Well, Haru did call you Dad, didn’t he?" Jin began, turning to face Jungkook, his eyes glinting mischievously. "But do you want me to call you that too? Although..." Jin leaned in closer, lowering his voice to a sultry whisper, "...I think ‘Daddy’ would work better, won’t it?"

Jungkook’s entire demeanor shifted instantly, his playful annoyance replaced by something darker, more intense. His eyes darkened with desire as he stared at Jin, his breath hitching. "What did you just call me?" Jungkook’s voice was husky, filled with a sudden hunger. "That sounded... sexy. Mind calling me that again?"

Before Jin could respond, Jungkook grabbed him by the waist, pulling him close, their bodies pressing together as the tension between them spiked. Jin gasped at the sudden movement, his teasing smile fading as Jungkook's lips crashed against his in a hot, demanding kiss. The intensity made Jin’s head spin, and without even thinking, he wrapped his arms around Jungkook’s neck, kissing him back just as fiercely.

Jungkook groaned into the kiss, his hands wandering over Jin’s body, gripping him tightly. Without breaking the kiss, he effortlessly picked Jin up, Jin's legs instinctively wrapping around Jungkook's waist. Jin let out a soft moan, feeling Jungkook’s strength and control, the heat between them rising with every second.

Jungkook carried Jin toward the bedroom, never once breaking their heated kiss. By the time they reached the bed, both of them were breathless, lips swollen from the passionate exchange. Jungkook gently laid Jin down on the bed, hovering over him, his eyes filled with desire. "Say it again," Jungkook murmured, his voice low and commanding. "Call me ‘Daddy.’"

Jin, flushed and breathless, bit his lip before smirking. "Daddy," he whispered teasingly, sending a shiver down Jungkook’s spine.

That was all it took to send Jungkook over the edge. He dove down to kiss Jin again, this time deeper, rougher, filled with pure want. His hands roamed Jin’s body, fingers trailing along his skin, making Jin shiver with every touch.

The air between them crackled with intensity as their kiss deepened, bodies pressing together in heated urgency. Every kiss, every touch felt electric, the room filled with the sound of their ragged breaths as they got lost in each other, the world outside forgotten.

The next morning, Jin stirred awake, the early sunlight filtering into the room. His body felt warm and relaxed, and for a moment, he almost forgot where he was—until he felt the weight of an arm draped over him. He blinked, turning slightly to see Jungkook lying beside him, still asleep, his face peaceful in contrast to the possessive intensity from last night. Jin's mind flashed back to the passionate night they shared, and his cheeks flushed.

Trying to quietly slip out of bed, Jin froze when Jungkook’s grip tightened around his waist. "Where are you going?" Jungkook's sleepy voice was deep, laced with a possessive edge. His eyes opened slightly, locking onto Jin.

"I… I thought I’d make breakfast," Jin replied, trying to keep his voice steady, though his heart raced at the closeness.

Jungkook smirked lazily, tugging Jin back down beside him. "Stay a little longer. No one's here to disturb us."

Jin narrowed his eyes. "Aren't you forgetting Haru?"

Jungkook’s smirk faltered, but he quickly regained it. "He’s with Jimin and Taehyung. They’ll keep him entertained."

Jin rolled his eyes, but before he could argue further, Jungkook shifted on top of him, trapping him beneath his body. "You’re not leaving just yet," Jungkook said, his voice filled with that same possessive tone, his eyes darkening as he leaned down to press a soft kiss on Jin’s lips.

Jin couldn’t help the flutter in his chest as Jungkook’s kisses grew deeper, but he pulled away slightly, his eyes meeting Jungkook's. "You're being more possessive than usual."

"Can you blame me?" Jungkook whispered against his lips. "After last night... I want to keep you all to myself."

Jin felt a warmth rise in his chest, but he tried to brush it off, pushing at Jungkook’s shoulder half-heartedly. "You can’t just…"

Before Jin could finish his sentence, Jungkook cut him off with another kiss, silencing his protests. "You're mine, Jin. And I don’t care if you don’t want to admit it yet. I’m not letting you go."

Jin’s heart pounded, and despite his best efforts, he could feel himself softening under Jungkook’s words and touch. He was still getting used to these intense feelings, but he couldn’t deny the pull between them—the way his body responded to Jungkook’s presence.

He sighed, pretending to be annoyed but failing to hide the smile tugging at the corners of his lips. "Fine," he muttered. "But you're making breakfast next time."

Jungkook chuckled, his grin widening as he kissed Jin again, savoring the victory. "Deal, sweetheart."
