Namjoon himself is not a big party person, but when his auntie had asked if they could hold his cousin’s birthday party at his home, he was more than willing to comply.
Hours of conversing, eating, and playing games went by in a flash. Now, the guests have all gone home so Namjoon begins tidying up the back garden. Burst balloons and streamers cover the grass, so he grabs a black trash bag to begin scooping them up. Paper plates and cups get cleared up with tables and chairs being folded and put away.
Namjoon lets out a sigh of relief once he’s all done. Glancing up at the sky, he can’t help but smile. The sunset is pretty, warm pinks and oranges spread as far as the eye can see. His heart flutters at the reminder; a similar sky to when he first met---
“Oof--” Namjoon jerks in surprise as he’s squeezed tightly from behind. “Baby, you’re here!” Namjoon chuckles breathlessly.
Jungkook easily accepts Namjoon’s embrace as he turns around to face him, smiling at the kiss planted lightly on his cheek. “How was the party?”
“Well, I’m exhausted. Guests left about an hour ago and I’ve just been clearing up since then,” Namjoon smiles at Jungkook’s cute face. “But it was fun. She had a good birthday.”
“Aw, that’s great! Sorry I couldn’t be there,” Jungkook presses more kisses to Namjoon’s face, showering him with love for a moment before he pauses suddenly.
“Hm?”
Jungkook’s gaze is fixed on the inflated bouncy castle behind Namjoon. He should’ve known.
Jungkook grins cheekily before he wriggles out of Namjoon’s grip and bounds over to the bouncy castle, slipping through the black netting curtain and inside.
“Yahoooo!” Jungkook exclaims, bouncing around with joy. “It’s been ages since I’ve been in one of these!”
Namjoon races over to join him, rolling clumsily inside. “I was so busy helping auntie with the party that I didn’t get time to bounce in here!”
“When do you have to get rid of it?” Jungkook asks, bouncing around Namjoon’s body, jostling him until he’s giggling and trying to grab Jungkook’s ankles.
“Tomorrow morning,” Namjoon says once he’s finally able to get up, bouncing around happily like a child.
Jungkook wiggles his eyebrows, “then you got time to bounce in it now. With me.”
Namjoon grins, a charming smile with dimples. “I wouldn’t have it any other way.”
Jungkook smiles back at him, bunny teeth and all, before jumping into Namjoon’s arms. Namjoon grabs his thighs, holding him up as best he can, wobbling as Jungkook kisses him on the lips.
As always, Jungkook’s kisses are so mind-boggling that Namjoon loses his footing, falling and bringing Jungkook down with him. They both erupt into fits of laughter, rolling around on the airbags until they’re facing each other. Namjoon looks at his boyfriend, his wide eyes shine at him, his cute smile makes his heart flutter.
“I’ve missed you,” Namjoon says softly.
Jungkook frowns, shuffling closer to Namjoon. “I’m right here.”
“I know, I’m so lucky,” Namjoon smiles, cupping Jungkook’s cheek and pressing their lips together.
Jungkook hums, pressing closer, wrapping his arms tightly around his boyfriend. He deepens the kiss, slips his tongue inside as Namjoon raises his eyebrows in surprise.
“Baby?” he murmurs against his lips, gasping as Jungkook pushes him onto his back. He has a glint in his eye that makes his stomach flip. “You...”
“I was just thinking...” Jungkook whispers, biting his bottom lip as his fingers trail down Namjoon’s chest. “Maybe we should make use of this bouncy castle?”
Namjoon smirks, trailing his hand up and down Jungkook’s back before slinking down to his ass, giving it a firm squeeze and slap. The generator should drown out the noises of their moans from the neighbours, so it’s not like it’s too risky an idea.
“You’re always full of such fun ideas.”
“You know it,” Jungkook wink-blinks.
“You need to practice that, baby,” Namjoon teases, pulling Jungkook in for another kiss.
Jungkook giggles into the kiss, hooking his leg over Namjoon’s hips until he’s on top of him. “Because you’re the expert in winking.”
Namjoon pulls back to wink both his eyes at Jungkook. “You know it.”
“I’m swooning,” Jungkook jokes, grinning down at Namjoon as he grinds against his crotch.
Namjoon gasps, his hands flying to Jungkook’s hips. “You don’t mess around, do you?”
“You should know that by now,” Jungkook smirks, pulling off his jacket and tossing it aside. He wets his lips in the way that he normally does, it’s not necessarily sexy but it still alights something in Namjoon, makes him pull his boyfriend close to kiss those sweet, wet lips.
Namjoon’s fingers find Jungkook’s bare torso as they slide up his T-shirt, his fingers drifting over his nipples in the way he knows his boyfriend likes. As expected, Jungkook mewls into his mouth and rocks against him harder.
Jungkook eagerly shimmies out of his jeans and underwear as Namjoon watches on with a smile. Jungkook is so pretty, so beautiful, so damn gorgeous. He doesn’t know how he got so lucky.
Then, his eyes catch a glimpse of something purple between Jungkook’s cheeks.
“Hey, hang on,” Namjoon utters, coaxing Jungkook into rolling onto his front, he teasingly squeezes his thighs before spreading them apart. Lo and behold, he’s wearing a butt plug. “You little demon!” Namjoon growls teasingly, slapping his ass cheek with a huff of a laugh. “You really came over wearing a butt plug?”
Jungkook chuckles, glancing back at Namjoon with a coy look. “Well, yeah. I haven’t seen you in a week. I was obviously coming over to seduce you.”
Namjoon swallows thickly, eyes fixed on the pretty, purple gem sticking out of Jungkook’s hole. “Does that mean...you’ll be able to take me? Right now?”
“I hope so,” Jungkook says, wriggling his ass. “That was the point, didn’t wanna wait. Take it out, hyung?”
Namjoon leans forward to press light kisses across his boyfriend’s cheeks as his fingers come to grip the end of the plug. He teases Jungkook a little, applying a little pressure, pulling it part of the way out before pushing it back inside. Jungkook’s needy mewls are heavenly.
“I don’t have a condom,” Namjoon says distantly as he finally pulls out the plug. He dips his thumb into Jungkook’s hole, biting his bottom lip at the easy, wet slide.
“You can breed me, hyung,” Jungkook says, shooting Namjoon a shit-eating grin. Namjoon knows he only says it like that to annoy him, but Namjoon’s cock can’t help but twitch anyway.
Namjoon huffs a laugh, lightly rolling his eyes before he spanks Jungkook again. “Okay, baby. I’ll breed you.”
“Don’t act like you don’t love it when I say that,” Jungkook chuckles, rolling onto his back with his legs eagerly parted. “Now let’s get this show on the road!” he claps his hands a little patronisingly with a cheeky grin. “Chop chop!”
“Someone’s eager,” Namjoon murmurs, though he can hardly have a problem with that. He makes quick work of his jeans and underwear, throwing them to the other side of the bouncy castle before shuffling towards Jungkook. Namjoon takes his time; hands caressing Jungkook’s thighs, delighting in the way Jungkook impatiently squirms.
“Hyung,” Jungkook whines, locking his legs tightly around Namjoon. “Let’s go , I’m--”
Despite being interrupted, Jungkook hums as Namjoon presses their lips together, melting into his embrace as Namjoon cards his fingers through his hair. He loosens his grip, becomes pliant as Namjoon dips his tongue into his mouth and snakes a hand down to Jungkook’s hard cock, giving a few, slow tugs. It’s then that Namjoon starts to press inside, cock twitching at Jungkook’s surprised gasp.
Namjoon inches inside slowly, just the head at first to test the stretch. It goes in with little effort, and Namjoon groans as he keeps dipping inside with his hands on the shaft to steady himself. “Fuck, you’re so warm and tight, baby... How long has it been?” Namjoon jokes, gingerly pressing in further. “I think I’m gonna have to run inside and get some lube, though.”
Shamelessly, Jungkook grabs his jacket, pulls out a bottle of lube and holds it out to Namjoon with wide, innocent eyes.
Namjoon is so in love. “You really did come here to fuck me.”
Jungkook nods honestly. “Uh-huh.”
“I won’t disappoint you,” Namjoon says earnestly, taking the bottle of lube before he captures his boyfriend’s lips.
Namjoon slathers lube onto his cock to help the slide, sinking in slowly until he’s completely buried in that tight heat. He lets out a long, shuddering breath.
“That’s my baby,” Namjoon utters breathlessly, squeezing his eyes shut for a moment as his senses are overwhelmed. Jungkook never stops feeling mind-numbingly amazing.
“I’m your baby,” Jungkook agrees, wriggling his hips with a low moan. “Fuck-Fuck me.”
He begins grinding slowly, the bounce from the bouncy castle helping him along, rocking them like they’re out to sea on a boat. It feels different, a little strange, but kind of nice. It’s good to change things up every one and a while, and as long as he has Jungkook like this, there’s not a lot that can be bad about it.
Jungkook pulls his boyfriend down to kiss him, sloppy and wet, slow like the movement of Namjoon’s hips. He makes little moans against Namjoon’s lips that drive him insane, he can’t help but jerk harder, slamming into Jungkook’s most sensitive parts.
“Feels so good,” Jungkook moans, still insistently keeping his lips pressed to Namjoon’s. He wraps his legs securely around his boyfriend but that seems to make him lose balance on the airbags as Namjoon slams into him, so he pulls away with a laugh.
“Are you comfortable like this?” Namjoon asks softly, pressing a kiss to Jungkook’s forehead.
Jungkook nods, wriggling his hips a little, “but maybe add more lube, hyung. I like it wet.”
“Me too,” Namjoon agrees, quickly getting on his knees and pulling out to cock to cover it in a generous amount of lube.
This time, when Namjoon presses back inside, he begins to use the extra bounce to leverage his thrusts. His pace is steady but fast, cock drilling into Jungkook with abandon. It’s wet and sloppy with lube running down Jungkook’s ass and onto the bouncy castle, Jungkook’s precome dribbling onto his belly in cute little bursts.
“Fuck, you’re making such a mess, baby,” Namjoon moans. “Never gonna get the deposit back on this thing.”
Jungkook chuckles breathlessly, “it’s worth it though, right?
“Fuck yeah, it’s worth it,” Namjoon grunts, enjoying the way his thrusts make Jungkook bounce. He looks beautiful, dark hair splayed out on the PVC as he’s jostled.
Jungkook grinds back against Namjoon to no avail, the bounce makes it impossible for him to get the angle he wants. Jungkook whines, pushing at Namjoon’s chest.
“Go, get off, we have to change positions,” Jungkook insists.
“Why?” Namjoon asks, still drilling into him regardless. “I like this position,” he says lowly, pressing his lips to Jungkook’s, nipping his top lip and licking inside.
“I know you do—and so do I but…” Jungkook pouts, squeezing Namjoon’s shoulders. “I can’t get you where I want you.”
Namjoon raises a brow, a smirk forming on his lips. “And where do you want me?”
Jungkook considers it for a moment with a purse of his lips. Suddenly his eyes grow wide. “I want to bounce on your dick!”
“Fuck, okay. That’s hot,” Namjoon agrees immediately, pulling out and moving to lay on his back.
Jungkook grins victoriously. “You know I’d never mislead you. We’re both as horny as each other.”
“True, I never should have doubted you,” Namjoon smiles up at Jungkook as he straddles his hips, reaching out to squeeze Jungkook’s thighs. “Fuck, you’re gorgeous.”
“Fuck, you swear a lot when we’re having sex,” Jungkook teases, slowly sinking down onto his cock with little effort.
Namjoon moans softly, squeezing Jungkook’s hips. “Can’t help it, baby, you’re fucking amazing.”
Jungkook laughs cutely, bracing his hands on Namjoon’s chest. “Love you.”
“Love you t—“
Namjoon gasps as Jungkook starts up a quick pace, needily bouncing on his cock. The bouncy castle rattles a little with the force of Jungkook’s movements. He wants it hard today, giving Namjoon no mercy.
“Fuck, hyung...Fuck, fuck, fuck, ” Jungkook moans, throwing his head back with a laugh as Namjoon raises a brow at him. “I get it. It’s hard not to swear when it feels this good.”
“Exactly,” Namjoon agrees, squeezing his eyes shut as his boyfriend rapidly slams down onto him, moaning when Jungkook sensually grinds against him.
“Good?” Jungkook asks sincerely, pausing with his wide eyes fixed on Namjoon’s face. “Hyung?”
“Good,” Namjoon agrees, looking up at Jungkook with a smile. “No one does it like you.”
Jungkook grins with a blush, chuckling as he gets back to his regular pace, bouncing on his boyfriend’s cock with the bouncy castle helping him along. “You were a virgin when I met you.”
“Yeah, but I’ve had sex with you - numerous times . I just know that no one does it like you.”
Jungkook coos at that, brushing some hair off his sweaty forehead before leaning down to kiss Namjoon. “No one does it like you, either,” he whispers.
“You’re damn right,” Namjoon growls, gripping Jungkook’s hips as he places his legs up, bucking up into Jungkook’s hole with as much force as he can muster. Jungkook’s moans are wonderful as he holds onto Namjoon, letting him have his way with him for just a moment.
“Shit...it’s hard to do that in a bouncy castle,” Namjoon chuckles breathlessly as he slows to a stop. “I’m tired already.”
“Then let me take care of you,” Jungkook grins, pecking Namjoon’s lips before he’s on his knees again. Namjoon’s fingers dip under Jungkook’s sweaty T-shirt so he quickly pulls it off.
“It should be illegal how good you look right now,” Namjoon says with awe, hands trailing up Jungkook’s sexy abdomen, stroking along his waist. “Look at this tiny waist, my hands can almost--”
Namjoon gasps as Jungkook sets up a rapid pace of bounces, moaning and panting with each thrust.
“Can’t...Can’t say stuff like that, hyung,” Jungkook says, squeezing his eyes shut and biting his bottom lip as he works himself on Namjoon’s cock. “You know--know what it does to me…”
“Oh yeah?” Namjoon smirks, large hands trailing up Jungkook’s thighs before reaching his cock, grasping him firmly until Jungkook mewls in pleasure and moves his hand away.
“I’ll come,” he whines, pushing up Namjoon’s t-shirt as far as it will go, squeezing his pecks like he often does.
“How are you not tired yet?” Namjoon asks with a laugh as he looks up at his bouncing boyfriend. “You’re incredible.”
“Feels so good...why would I...want to stop?” Jungkook pants, tilting his head back as he finally slows to a grind. He looks delicious; sweat beading at his forehead, long hair messy, cheeks flushed and pretty.
Namjoon holds Jungkook’s hips firmly to try and still him. “So I can take care of you?”
“Hey, I’m not done yet. This is fun!” he chuckles as he bounces exaggeratedly, rocking them up and down on the airbags.
“Okay but...I’m not sure how much longer I can last and I really want to fuck you from behind...please, baby?”
“Well...I do love getting fucked from behind,” Jungkook states with a purse of his lips, Namjoon nodding enthusiastically. “And you do it really well...”
“Thank you.”
“And I do love you a lot. Enough to give you whatever you want.”
“Love you too. I would give you the world.”
“The world? Isn’t that a bit much?”
“Probably, but I’m in love,” Namjoon grins with a wink.
Jungkook giggles cutely, leaning down to plant a kiss on Namjoon’s lips. “Okay, sure,” he agrees, lifting himself off Namjoon’s cock before launching himself onto the bouncy castle. Namjoon chuckles at the cute way he bounces. “Make me come, hyung.”
“I got you, baby. I’ll breed you,” Namjoon can’t see Jungkook’s grin right now, but he knows it’s there.
Jungkook lifts himself onto all fours so Namjoon can press inside again. It’s not long before Jungkook loses balance with the force of Namjoon’s thrusts, instead laying with his face pressed into the airbags. Namjoon is like a jackhammer as he thrusts into his hole, the sound dirty and wet, lube dripping down Jungkook’s thighs as he moans, the squelch is delicious .
“I’m close, baby,” Namjoon groans, pressing himself against Jungkook’s back with one hand around his waist, one hand around his cock.
“Hyung, hyung,” Jungkook moans, drooling onto the bouncy castle as his boyfriend rams into his prostate. “There… keep-- ah --coming, coming…” Namjoon’s cockhead is nailing Jungkook’s prostate with his hand jerking him to completion, Jungkook trembles and shakes with the force of his orgasm, semen spurting out onto the bouncy castle.
“Coming --” Namjoon hips jump and jerk as he comes close to orgasm, holding onto Jungkook tightly as he buries himself inside and spills his cum. He grunts as he thrusts through his orgasm, letting Jungkook’s hole milk him for all he’s worth.
Jungkook knows when Namjoon has come back to himself because of the light kisses on the back of his neck.
“It’s so sticky...” Jungkook slurs as Namjoon pulls out, cum oozing out his hole.
“You look so gorgeous with my cum in your ass…” Namjoon muses with awe, large hands caressing his ass cheeks, thumb dipping inside as Jungkook jerks in oversensitivity.
“So I don’t normally look gorgeous?” Jungkook huffs, faux-offended as he rolls onto his back.
“You always look gorgeous. With or without cum all over you.”
“Aw, romantic,” Jungkook snorts, shuffling over to Namjoon to rest his head on his chest.
“Fucking in a bouncy castle...doesn’t get more romantic than that,” Namjoon says, taking Jungkook’s hand in his, idly playing with his fingers and bringing them to his lips to kiss.
“Can we order takeout and eat it in here too?”
“We just fucked in here,” Namjoon laughs in disbelief. “It’s all gross and sticky.”
“I mean after we clean it. Then it’d be like a proper date.”
“You put out very quickly. Couldn’t even buy me dinner first, could you?” Namjoon teases.
“What can I say? I’m weak for tall, dimpled men with cute noses and kind eyes and warm smiles and--”
“And big dicks?”
“I was getting to that,” Jungkook chuckles, accepting Namjoon’s lips once again in a sweet kiss.
