Kim Namjoon all but sprinted into the apartment that he shared with his boyfriend of several years. Said man was no doubt sitting on their bed still in his work suit patiently waiting for his arrival. The image of the man lounging in bed with his tie loosened and the first few buttons of his shirt undone had Namjoon’s mouthwatering. He hurried through the apartment to their bedroom so quickly that he stopped in front of Seokjin panting and red-faced.
The other man merely gazed at him over his glasses with an indifferent look. He took in the man’s dishevelled appearance and suppressed a smirk. Tonight was going to be new and exciting for both of them.
“Get undressed and kneel,” Seokjin ordered without another word. At this point in their relationship, he didn’t need to preface his orders with anything, just one look sets either of them in the appropriate headspace. The other man flushed as he registered the words as if he hadn’t heard that same phrase spoken hundreds of times. At the man’s hesitation, Seokjin raised an eyebrow. “Do I need to repeat myself?”
“No daddy,” Namjoon replies quickly and began undressing. If possible, the man flushed darker as he took off his shirt and Seokjin soon found out why. The man was wearing a lilac lace bralette. Seokjin assumed that he was wearing the matching panties too and scoffed at him.
“Wow, what a slut walking around with slutty underwear on under your clothes. What would your coworkers think?” Seokjin chastised. His words were harsh but his voice was soft. They’d learned quickly that Namjoon never responded well to a harsh tone. Namjoon whined in embarrassment as he finished taking off his pants. “Leave your underwear on, baby.” Namjoon nodded at the man and knelt down between Seokjin’s spread legs.
Seokjin ran his fingers through the other man’s hair, scratching softly at his scalp and tugging the hair in ways to make his eyes flutter shut. “Look at me, baby girl,” Seokjin urged gently. Namjoon’s eyes snapped open in attention. “Daddy got you a little present.” With that, he reached behind him and grabbed a box that was laying on the bed. Gently, he opened the box and pulled out a thick, black leather collar. Namjoon stretched his neck out so that Seokjin could put it on him. With the utmost care, Seokjin secured the collar on the man’s neck, double and triple checking that it wasn’t too tight. When it was all secured, he leaned back to get a better view of his baby. From the metal loops hung a tag that read “Property of Kim Seokjin” that laid delicately in the hollow of Namjoon’s collarbone.
“Now, what’s this I hear about you wanting our little bunny, Jeongguk?” Namjoon’s eyes widened at the playful tone. They locked eyes and he could see the question in Seokjin’s eyes asking if this was okay. Usually, they’d plan out their scenes and talk beforehand but today was a different story. Seokjin couldn’t help but worry about pushing Namjoon too far but he trusted that the man would safeword if he needed to.
“I really like him, Daddy,” Namjoon replied.
“More than me?” Seokjin pouted.
“Never!”
“Am I not good enough for you, baby?” Namjoon squirmed at the scrutinising look he was getting. “You really are greedy, huh? You can’t just have one of us.” The other man nodded.
“I want you both, Daddy.”
“My greedy little girl,” Seokjin cooed. “Get on the bed, baby girl. Face down on your knees.” Namjoon whined but obeyed the order. He situated himself so that his ass was up in the air, still covered by the lace panties.
“M’sorry, Daddy,” Namjoon whined. Seokjin looked at him in confusion.
“Why are you apologising, baby?”
“M’too greedy.”
“Aw, baby,” he cooed. “I’m not punishing you, baby girl. I’m gonna reward you for telling me the truth,” Seokjin clarified. Namjoon seemed to glow at that. “You know, Daddy really likes Gukkie, too.”
“What would you do if he was here, Daddy?” Namjoon asked. Seokjin shuffled behind him and grabbed his hips. Namjoon arched his back and pushed his hips back towards Seokjin.
“Hm, I wonder. Maybe I’d tease him until he cried. He’s so cute and innocent, it makes me wanna wreck him.” Namjoon seemed to like this as he moaned into the mattress. “Maybe I’d tie you up while you watch me take care of little Gukkie so you can’t touch yourself. Would you like that baby?”
“Yes, Daddy,” he moaned out then mumbled something else.
“What was that, baby girl? Daddy can’t hear you.”
“Wanna touch Gukkie, too,” Namjoon said as he lifted his head away from the mattress.
“Yeah? You wanna fuck Gukkie?” Namjoon whined. “But baby, it’s been so long since you’ve been inside someone, do you think you’d even last. Remember what happened when we used the fleshlight?” Namjoon flushed down to his neck. Of course, he remembered. It was the hardest he’d come ever and it happened in mere seconds.
“I can do it,” Namjoon panted out.
“I’m sure you can, baby girl. But we’ll have to get you a cock ring just in case.” Namjoon was positively shaking at this point, his thighs trembling with arousal. “God, I can’t wait to make him ours.” This time it was Seokjin who moaned as he pressed against Namjoon’s backside.
“Please, Daddy….”
“Please what, baby?” Seokjin teased.
“Please fuck me.” Seokjin couldn’t help the moan that slipped out as he reached into their bedside table for the lube and condoms. He made quick work of his clothes and returned behind the trembling man. He reached for the man’s panties and slowly pulled them down to reveal his puckered hole, which was surprisingly stretched around a plug. “Jesus, baby. Are you trying to kill me?” Namjoon laughed breathlessly.
“I wanted to surprise you, Daddy.” He wiggled his butt a little to tease the other man, which only caused a light smack across his cheeks.
“Don’t be a tease or you’re not getting anything.” They both knew that it was an empty threat. It was easy to tell how wound up Seokjin was, his cock a deep shade of red. Obviously talking about the other boy got them both worked up.
Without another word, Seokjin slowly pulled out the butt plug, careful not to hurt Namjoon. When the plug was fully out, Namjoon whined and clenched around nothing. Making double sure that he was prepped, Seokjin applied a generous amount of lube onto his fingers and inserted three into the man. He was still a little tight, so he slowly loosened the man up, working his fingers inside of Namjoon whilst rubbing his back. He did this all while gently cooing at the man.
“So good for me, baby girl. You take my fingers so well.” Namjoon whined and moaned the whole time before he began begging for the other man’s cock.
“Please, Daddy, m’ready,” he begged. Just to tease the man one more time, Seokjin gently brushed his fingers against Namjoon’s prostate as he pulled out, causing him to cry out.
“Okay, Daddy’s gonna fuck you now. I want you to say his name too okay?” Seokjin ordered gently. He waited for Namjoon’s nod before he began putting on the condom and lubing himself up. He slowly pushed inside of Namjoon, stopping when the man tensed up and continuing when he relaxed again. Soon, he was fully seated inside the other man. Here, he paused again and waiting for Namjoon to give him the word.
“Move, please.” There it was. Without a word, he slowly pulled out until the head of his cock caught on the rim and slammed back in. He continued this pattern, causing Namjoon to cry out. They both knew that after all of the teasing, neither of them were going to last very long.
“Say his name, baby,” Seokjin ordered.
“J-Jeongguk!” Namjoon cried.
“That’s a good girl. Do you think he’d be this good for me? Or maybe he’ll be a brat at first and try to fight me?” Namjoon started moaning out incoherent syllables that vaguely resembled Seokjin and Jeongguk names. “God, he’d look so pretty all spread out for us. Our little bun. All for us.” Seokjin broke off his rambling to moan loudly. He was getting close so he began to piston his hips. He reached around to gently stroke Namjoon’s cock. “You’re so wet for me, baby. Are you gonna come?” Namjoon babbled out yeses. “Go ahead, baby girl. Come for me.” Without another word, Namjoon came with a loud cry of Jeongguk’s name. After a few more thrusts, Seokjin followed after him.
The two men collapsed onto the bed, utterly spent. Suddenly, Namjoon began giggling, causing Seokjin to look at him curiously.
“I haven’t come that hard since the fleshlight,” he said while laughing.
“So it was good?” Seokjin asked.
“More than good.” With that, the conversation was mostly over and Namjoon shuffled over to cuddle Seokjin. After a few moments, Namjoon spoke up again. “I really like him, hyung.”
