Summary:

Jeno’s always been the quiet and a bit of a nerd, and Jaemin never thought much of it—until one time Jaemin shows up wearing Jeno’s favorite shirt, looking very irresistible. After a year of being together, Jaemin’s stunned to discover that Jeno, who always seemed so calm and reserved, is still capable of getting a boner.

Work Text:

Jeno places his phone on the table, casually sitting on the couch in the most comfortable position—his arm resting on the back of the couch, legs spread, while a random movie plays in front of him. He waits for Jaemin to finish washing up and changing into his own clothes, wanting the both pf them to get comfortable and clean up before going to bed.

‘I can fall asleep like this,’ Jeno thinks, his eyes growing heavier each second. He had napped for a few hours after lunch, only getting up for a short walk to the campfire, which was something Jaemin had desperately begged for (he loves s’mores to death). But of course, that seven-hour drive was still a seven-hour drive. 

He sinks a little deeper into the couch, feeling more relaxed because his muscles were still sore from the trip. Luckily, he starts to hear Jaemin’s footsteps near the living area, and once he sees him, Jeno forces himself to sit up straighter, suddenly a lot more awake than he’d like to admit. He pretends to stretch, fingers raking through his dark locks casually.

Jaemin shyly stands in front of him, looking at his boyfriend with his signature pout, linking his hands together as if he’s about to confess something horrible. Well, at least that’s what he thinks  

“Baby, hehe. Sorry. I overpacked but I forgot my… uh.” Jaemin explains, smiling at Jeno apologetically before he walks toward the couch and about to sit next to Jeno.

Jeno shifts slightly, trying to casually drape a throw pillow over his lap without being too obvious. His heart races as Jaemin successfully sits next to him, who was seemingly unaware of the problem his boyfriend is facing.

But who could blame Jeno for reacting that way?

Jaemin has always had a way of looking effortlessly cute, but also very hot—no one knows if he’s aware of that—especially now, sitting there in an oversized shirt that hangs loosely on his frame, the neckline slipping just enough to show a portion of his collarbone.

Curiously, Jeno asks, “That’s… my shirt?”

Jaemin nods. “Mhm. Is it okay? I forgot my pajamas, hehehe. I was going to wear my shirt but I was going to use it for my outfit tomorrow, and you told me a while you have extra shirts for me to use in case I get sweaty from our hike. So I just grabbed one and used my spare shorts.”

It takes Jeno a few seconds to process that.

His shirt… yeah. His favorite shirt that explains how it fits loosely around his boyfriend, which also caused the problem he’s suddenly facing. Jeno has always liked his shirts a bit loose. Damn. His fault. 

“Oh, uh, yeah. It’s alright, Nana,” Jeno mumbles, trying to play it cool. “You… you look good in it.”

Jaemin smiles cheekily, then wraps an arm around Jeno’s waist. He places his leg on top of the older’s as he starts to snuggle up to him, sniffing Jeno’s scent. “I’m so tired. Thank goodness you’re my cuddly bubby. And.. you smell so good.”

But then, a few seconds later, Jaemin notices that something is off. Normally, by now, Jeno would’ve wrapped him up in a full embrace, holding him tightly and babying him like always. However, Jeno is just pulling him closer with one arm, his hand absentmindedly rubbing Jaemin’s side in what feels more like a distracted attempt to cuddle him.

“You okay, baby?”

“Mhm. Just a bit exhausted.” Jaemin squints his eyes. The laugh is so forced. He is so sure he already has Jeno figured out from their one-year-old relationship, so something is definitely… off. He highly hopes it’s nothing too bad.

“You sure? You feel... stiff. You don’t wanna cuddle?” He pouts as he presses a little closer, his brow furrowing as if trying to figure out why Jeno isn’t his usual clingy self. 

If Jeno could hear Jaemin’s thoughts, he would agree. He just tells himself he’s going to be a clingy baby tonight.

Jeno shifts again, his fingers tightening on Jaemin’s side, somehow trying to steer the conversation. “I’m good, promise,” he says quickly. “I might just be really tired.” He gives Jaemin a cheeky smile, but that isn’t convincing his boyfriend, whose eyes are now narrowing in suspicion. Hmm.

“But you never act like that when it’s cuddle time,” Jaemin responds with a pout, moving closer to Jeno, which made their faces stand a few inches away from each other, clearly not helping Jeno’s situation at all.

“Ah... uh, I don’t know, Nana. But I’m not complaining, okay? We can cuddle.”

Jaemin, who is still unconvinced, frowns a little, adjusting his position as he continues to cuddle up against Jeno. He squirmed slightly, the throw pillow between them started to feel like it’s making a bit of an annoyance. “Why is this even here?” Jaemin mutters, casually reaching for the pillow.

Jeno’s eyes widen in panic. “Uh—baby, wait—”

Before he can stop him, Jaemin has already pulled the pillow away, tossing it aside. The second it is gone, Jaemin freezes. His eyes flick downward, and he immediately notices the very obvious reason Jeno has been acting so strangely.

“Oh.”

“I swear, I didn’t mean to.”

Jaemin giggles, shaking his head at his poor boyfriend whose cheeks are now flushed red, fixing his glasses as he doesn’t know where to divert his attention anymore.

“Baby, this is how you’re affected by… me?” The younger teases, placing a gentle kiss on Jeno’s heated cheek.

“I mean… I guess, maybe? Yeah. Haha.”

Jaemin laughs again, throwing his arm around Jeno’s shoulders, pulling him into another, tighter hug, showering his boyfriend with more kisses.

“You are so, so cute!” He teases. “You didn’t have to suffer in silence, you know! You should’ve said, ‘Nana, I’m getting hard—”

“Nana!”

Jaemin giggles as he continues to tease him. “What? I’m just saying.”

“I don’t know… that’s why I didn’t bring it up, it sounds a bit embarrassing. Don’t mind it, it will eventually calm down.”

The younger rolls his eyes. “Still, baby. It’s not like it’s not okay with me. It’s normal.”

“We haven’t gotten this far.”

“We eventually will go this far, baby. But I’d appreciate it too if you’d let me know next time,” he says with a playful shrug. Then, without a second thought, he moves to sit right on Jeno’s lap, settling himself comfortably. He continues to playfully tease him, “so you know, I can help you.”

Jeno’s breath catches in his throat as Jaemin adjusts, completely oblivious to the next level of difficulty he has to face.

The older forces himself to focus on anything else, but it is just impossible. With Jaemin on his lap, teasing him without even realizing it, things have become... very, very hard.

Literally.

 

────

 

Well, the next steps are easy. Because all Jaemin has to do is wrap his arms around Jeno’s nape, kiss him like there’s no tomorrow, let his palm wander around Jeno’s body, and there. Jeno can already feel his climax nearing.

“Baby, princess, I’m really about to… if you keep doing that.”

It’s not as if Jeno doesn’t have the same effect on Jaemin. The younger is also struggling hard with how tight his shorts are starting to feel. With Jeno’s hands gripped tightly on his bare waist, his hands already under the shirt, the kiss turning messier and messier, he is just as eager for more.

“Then go. No one’s stopping you.” Jaemin mumbles against Jeno’s lips. If he’s going to be honest, his mind is already all over the place. If it were a regular day of them making out on the couch, things would fall into place like they always used to.

But even Jaemin can’t understand how he’s simply just wanting… more. More that he starts grinding his hips in a steady manner.

Normally, Jeno would’ve stopped him before things could escalate. But even the older is too into the moment that he adjusts his seat so Jaemin can sit properly on top of him, guiding his hips.

“Touch me, please,” Jaemin whispers, pulling away from the kiss momentarily as he focuses on rolling his hips. He can definitely feel something hard between his buttcheeks, but knowing that he is the reason why it still hasn’t calmed down only makes him want to do better.

Of course, Jeno is very easy to give orders to. He is a very loyal man who listens to his baby’s wants.


He moves his palms upward, feeling Jaemin’s bare skin against his own, caressing it softly as he can’t do anything but worship the being in front of him.

“You’re so pretty. So, so pretty.”

He can see his boyfriend’s eyes rolling upward every time his thumbs faintly reach his nipples, how soft groans and whimpers escape Jaemin’s soft, plump lips.

Even he could get off to that.

“More, please, Jen,” Jaemin’s words become breathier as he pleasures himself on Jeno’s lap, his palms pressed against Jeno’s shoulders.

Jeno continues to touch him, experimentally circling his thumbs around his sensitive nubs. His breath hitches as he feels himself getting closer, too. He grips Jaemin’s waist tighter, his movements growing more desperate. “More, princess?” he asks, though the man’s reaction makes the answer obvious.

The nickname doesn’t help. “Please,” Jaemin groans, his hips moving in a steady rhythm, pushing against Jeno’s lap. His eyes flutter shut as he loses himself in the sensation, desperate for release.

Feeling the urgency in Jaemin’s movements and hearing his increasingly ragged breaths, Jeno knows they won’t last much longer in their current position.

He pulls away slightly, locking eyes with Jaemin. “You wanna continue this in bed, love?”

Jaemin looks up at him and nods.

“You sure?”

“A hundred percent. I want you, Jen,” he mumbles shyly, wrapping his arms around Jeno again and hiding his face in the crook of his neck, embarrassed by his response.

Jeno finds him both silly and cute. “I want you just as much, princess. I want this as much as you do. I just want to make sure you’re ready.”

“I am. Are you?”

“From the moment I knew you were going to be the person I’d be with for the rest of my life, I knew I was ready to surrender every part of my being to you, completely and irrevocably.”

Jeno earns a playful slap on the back from Jaemin, and they both giggle at his cheesy response.

How can this man still be so romantic when his crotch is probably aching under his sweatpants? Jaemin wonders, but his thoughts are soon clouded again with yearning and need as he feels lighter on top of Jeno. Jeno carries him effortlessly to the bedroom, making sure the lights are dim enough for privacy but bright enough to see each other.

Jeno places a soft kiss on Jaemin’s temple before laying him flat on the soft mattress and positioning himself on top of him.

“You’re so pretty. I can’t believe I have you all to myself.”

“You’ve been saying that a lot today.”

“What? Can’t I praise my pretty princess?” Jeno teases, slowly stripping off his shirt as he feels the heat spreading over his body.

He’s about to do the same to Jaemin, who seems eager to be touched as well, when Jaemin stops him.

“You want to keep it on?” Jeno asks.

Jaemin shakes his head and points at the four plushes next to them, pouting as Jeno’s gaze returns to him. “They’ll see me topless.”

“Hahaha, should I put them on the couch?”

“No. Just… place them on the bed bench, then turn around and cover with the blankie.”

Trying not to burst into laughter, Jeno complies and does as asked, making sure none of the plushes are facing their way.

“All good?”

Jaemin nods, and that’s all the signal Jeno needs to dive in and kiss him with passion, slowly rekindling the momentum as they yearn for each other’s touch.

Jaemin’s legs wrap around Jeno’s waist, his arms around Jeno’s neck as their kiss grows sloppier, fueled by the heat of the moment.

Jeno brings his palm back under Jaemin’s shirt, caressing his sides as he becomes more aware of his lover’s sensitive spots. The shirt becomes too much of a barrier, though, so Jeno pulls away to gently strip it off Jaemin.

Before he can toss it to the floor, Jaemin grabs it and reaches for Jeno’s glasses. “It got fogged up.”

It’s too endearing to see the love of his life—though seen through blurry eyes—caring for him so thoughtfully in such an intimate moment. Jeno would even cry on the spot if he could, moved by how Jaemin’s attention to the smallest details makes him feel truly seen and cherished.

Jaemin carelessly tosses the shirt to the floor and carefully places Jeno’s glasses back on his face, then places a soft kiss on his nose. “Handsome.”

“Of course. The pretty boy needs a handsome boy.”

“And the pretty boy needs you right now. So kiss me, please.”

Their lips latch on to each other again, their hands and legs tangling as they want nothing more than each other.

Jeno’s kisses soon shift from Jaemin’s now bruised lips down to his neck, inhaling the sweet scent of his lover that gradually becomes addictive. The soft kisses turn rougher, mixed with need as he licks and sucks on Jaemin’s delicate skin. He considers it a work of art, marking his boyfriend with red and purple marks, showing that Jaemin belongs to him and only him.

“More, please, baby,” Jaemin’s grip on Jeno’s dark locks tightens, urging him to move his head down to his chest. Jeno can only worship him and his body, kissing and touching him all over as Jaemin desires. The sensitivity peaks when Jeno’s tongue makes contact with Jaemin’s nipple.

“Hm— fuck, oh my god, Jeno,” thankfully, their place is secluded enough that no matter how loud Jaemin gets, only Jeno hears this kind of music.

Jeno uses his tongue to play with Jaemin’s erect nipple, sucking on it occasionally while his fingers play with the other, pinching it simultaneously. This causes Jaemin to arch his back, his own cock aching even more under his shorts.

“Jen, I want you, please. I can’t take it anymore,” Jaemin mumbles in desperation, with Jeno unconsciously pleasuring Jaemin for his own satisfaction as well.

“Okay, my pretty princess. You’ll have me,” Jeno moves back on top of Jaemin, showering him with gentle kisses and rubbing their noses together. “I love you.”

“I love you,” Jaemin exhales, smiling at Jeno sheepishly as he removes both of their remaining clothes, leaving them bare under the moon.

Once he gets Jaemin prepped and his own shaft lubed up, he looks back at Jaemin, who lies on the bed in the most comfortable position he can manage at this moment. His plump lips are slightly parted, his cheeks adorned with the softest shade of pink, and his eyes sparkle more brightly than the stars.

“Baby, are you crying?” Jaemin frowns as he wonders if he’s seeing correctly, pulling Jeno down to wipe the single tear that slides down his cheek before giving him a soft peck.

Shaking his head and pulling himself back to reality, Jeno chuckles. “Sorry, baby. I didn’t even notice. You’re so pretty. Irrevocably beautiful. I just forgot what to do with myself with someone this beautiful in front of me right now.”

“You’re crazy.”

“For you, yes.”

Jaemin chuckles. “Obviously. And it’s not obvious, but I’ve been feeling all giddy for a while now, see? You think you’re not godsend and beautiful yourself.”

Jeno pinches Jaemin’s cheek before folding his legs up. “Mhm. Whatever you say, princess.”

He lets the younger’s heels rest on his sides while his tip pokes Jaemin’s entrance. It takes a single nod of assurance from Jaemin before Jeno slowly moves forward, groaning at the sensation as Jaemin’s tight walls envelop his cock.

“God, you’re so big. What the hell.”

“Sorry. It’s not fully in yet, though…” Jeno hears Jaemin curse but continues to slowly push himself in, intent on causing as little pain as possible. “Nana, it’s squeezing me.”

“Shh!” Jaemin playfully slaps Jeno’s shoulder, and they both giggle, trying to mask their pain and pleasure as Jeno fully inserts himself inside Jaemin.

Jeno buries his face in the younger’s neck, and Jaemin tilts his head to grant Jeno more access.

After a few more seconds, Jaemin signals Jeno to begin moving. “Love, ‘m ready.”

Jaemin wishes he was prepared for the indescribable feeling once Jeno starts moving his hips with fervor. He starts slow and steady, but god, he’s so deep into Jaemin that the latter can feel his insides probably getting rearranged.

“Jen, mmh, there, please. Just like that—oh my god.” Jaemin whines, barely noticing the words spilling from his lips as he gasps for air while Jeno continues to fuck him into oblivion.

Jeno thrusts harder and deeper but maintains a slow pace, not wanting to hurt Jaemin any further. “Princess, you’re so tight. God, fuck.”

They can only cry in pleasure, marking each other while claiming each other. Jeno paints Jaemin’s neck with sloppy kisses in an attempt to distract the younger from the added pain, sharing the same discomfort as Jaemin scratches his back with nails digging into his skin.

The room is filled with the sounds of their skin slapping, their moans, and their whimpers. With one final cry, Jaemin reaches his climax, spilling his fluids all over his abdomen and chest.

“In me, please, love,” Jaemin almost begs, still high from the sensation and sensitive from his release.

“Fuck, baby,” Jeno’s thrusts become messier as he nears his own climax, gladly fulfilling Jaemin’s request and filling him to the brim with his fluids.

He doesn’t pull out, instead resting on top of Jaemin as they both catch their breath.

It takes them a minute to regain their senses, looking at each other with smiles on their faces.

“You’re amazing.”

“No, you are. Didn’t know you had that in you, bubby. Where did you learn that?” Jaemin teases, brushing Jeno’s hair with his fingers as they both giggle at their situation.

“It doesn't matter where I learned it, baby. What matters is who I’m using it on—and that’s all you.”

One might think they are crazy for making light of such an intense moment, but they are left chuckling and giggling in their disheveled state. Their hair is messy, lips are bruised, sheets are soiled, and breaths are heavy.

But at that very moment, nothing else matters to them.

It’s just Jeno and Jaemin, nothing else.

Except for the fogged-up windows that Jaemin should probably wipe with his shirt afterward.
