Work Text:
Mark has spent countless nights with Donghyuck, but none quite like this. It's different tonight—Donghyuck's hands keep finding their way to his stomach, his waist, pressing down with an intent Mark doesn't understand at first. He's too caught up in the way Donghyuck's fucking into him, deep and steady, to notice the pattern until Donghyuck speaks.
"God, look at you," Donghyuck breathes against his neck, fingers splayed across Mark's abdomen. "You'd look so fucking good carrying my kid."
Mark's brain short-circuits. His mouth falls open but nothing comes out, just broken little noises as Donghyuck keeps moving. The words shouldn't affect him this much, shouldn't make his thighs shake and his cock leak, but they do. They really fucking do.
"What—what the fuck?" Mark manages to gasp out, but his body betrays him, clenching around Donghyuck's cock. Donghyuck just laughs, low and dark, pressing his palm harder against Mark's stomach.
"You heard me," Donghyuck says, and Mark can hear the smirk in his voice. "I've thought about it before. Getting you pregnant." His hips snap forward sharply, making Mark cry out. "You'd be so pretty."
Mark's face burns. He knows it's impossible, knows Donghyuck knows it too, but something about the way Donghyuck's saying it—like he means it, like he wants it so badly—makes Mark's head spin. "Hyuck," he whimpers, and he doesn't even know what he's asking for.
"Yeah?" Donghyuck's voice is rough. His hand slides up Mark's chest, then back down to his stomach. "You like that idea? Like thinking about me breeding you?"
Mark can't answer. His mind's gone blank, overwhelmed by the feeling of Donghyuck inside him and the weight of his words. He just moans, high and desperate, as Donghyuck fucks him harder.
"Fuck, you do," Donghyuck groans. His fingers dig into Mark's skin. "You're getting tighter. Getting wetter for me." He presses down on Mark's stomach again, and Mark swears he can feel Donghyuck's cock through it. "Gonna fill you up so good, baby. Keep you full until it takes."
It's ridiculous. It's absolutely fucking ridiculous, but Mark's never been closer to coming in his life. Every word out of Donghyuck's mouth makes his cock throb, makes his hole clench greedily around Donghyuck's length.
"Want it so bad," Mark slurs, voice gone high and breathy. His fingers twist in the sheets as Donghyuck's thrusts get rougher, more desperate. "Please, Hyuck, fuck—need you to fill me up."
Donghyuck groans, burying his face in Mark's neck. His teeth graze the sensitive skin there, and Mark shudders. "Yeah? You'd let me? Let me keep you like this until you're showing?" His hand slides down to grip Mark's hip, fingers digging in hard enough to bruise. "God, I'd take such good care of you. Keep you in bed all day, just like this."
Mark's lost in it now, caught up in the fantasy. His cock aches where it hangs heavy between his legs, dripping onto the sheets. "Please," he begs again, not even sure what he's asking for anymore. Everything feels too much and not enough at the same time.
"Fuck, baby, you're perfect." Donghyuck's rhythm starts to falter, his breaths coming faster against Mark's skin. "Gonna come soon. Want me to fill you up? Get you nice and full?"
Mark nods frantically, pushing back against Donghyuck's thrusts. His whole body feels like it's on fire, pleasure building low in his stomach. "Yes, yes, please—need it, need you to—" He breaks off with a choked moan as Donghyuck hits just the right spot inside him.
Donghyuck's hand moves back to Mark's stomach, pressing down firmly. "Look at how well you take me. Made for this, aren't you? Made to carry my kids." His voice is wrecked, barely more than a growl. "Gonna come so deep in you, make sure it takes this time."
That's what does it for Mark—he comes with a broken cry, untouched, clenching tight around Donghyuck's cock. His vision goes white at the edges as pleasure crashes through him in waves.
Donghyuck follows right after, hips stuttering as he fills Mark up. His grip on Mark's stomach tightens, and he moans Mark's name like a prayer. They stay like that for a moment, both trying to catch their breath, before Donghyuck slowly pulls out.
Mark winces at the feeling of come dripping down his thighs, but Donghyuck's there immediately, fingers trailing through the mess. "Shit," he breathes, pressing two fingers back inside Mark's sensitive hole. "Look at you. All messy with my come."
"You're fucking insane," Mark mumbles into the pillow, but there's no heat behind it. He's too fucked out to even pretend to be mad about the way his cock twitches weakly at Donghyuck's words.
Donghyuck just laughs, soft and fond, as he pulls Mark close. His hand finds its way back to Mark's stomach, rubbing gentle circles. "You loved it though."
Mark doesn't answer, but they both know he did. He lets himself drift off to sleep with Donghyuck's warmth at his back and Donghyuck's hand still pressed possessively against his stomach.
When Mark wakes up the next morning, his body aches in the best way possible. Donghyuck's still wrapped around him like a clingy octopus, breathing softly against the back of his neck. Mark shifts slightly and immediately regrets it—his thighs are tacky with dried come, and his hole feels tender and used. He should probably be disgusted, should probably drag himself to the shower, but there's something about being marked up like this that makes his stomach flip.
"Stop thinking so loud," Donghyuck mumbles, tightening his arm around Mark's waist. His hand slides down to Mark's stomach again, and Mark's breath catches. "Fucking hell, you're still so sensitive."
"Shut up," Mark grumbles, but he doesn't move away. His mind keeps drifting back to last night, to the things Donghyuck said, the way they made him feel. It should have been weird. Should have freaked him out. Instead, he's half-hard just thinking about it.
Donghyuck must notice, because he huffs out a laugh and presses closer. "Someone's eager this morning." His fingers trace idle patterns on Mark's skin, dipping lower with each pass. "Still thinking about what I said?"
Mark bites his lip, trying to hide how much Donghyuck's words affect him. It's futile though—his body gives him away, cock already leaking against his stomach. He can feel the ghost of Donghyuck's hands from last night, the way they'd pressed into his skin like they were trying to leave permanent marks. The memory alone makes his thighs tremble.
"You're fucking obsessed," Mark breathes out, but his voice breaks on the last word as Donghyuck's fingers find a particularly sensitive spot. His hips buck forward without his permission, chasing more of that touch. "What's gotten into you lately?"
Donghyuck hums against his neck, clearly pleased with Mark's reaction. His palm slides flat against Mark's stomach again, proprietary and possessive. "Can't help it. You just—fuck, you look so good like this. All marked up and full of my come." His fingers press down slightly, making Mark gasp. "Been thinking about it for weeks. The way you'd look if I actually could get you pregnant."
"Weeks?" Mark's voice comes out embarrassingly high. His face burns but he can't stop himself from asking, "What do you mean weeks?"
"You really haven't noticed?" Donghyuck's laugh is low and dark against his skin. His hand trails lower, wrapping around Mark's cock in a loose grip that's more teasing than satisfying. "The way I keep touching your stomach? How I always come inside you now?" He tightens his grip just enough to make Mark whimper. "Been wanting to tell you for so long. Wanted to see if you'd figure it out yourself."
Mark's mind races, trying to piece together all the little moments he'd missed. The lingering touches during practice, the way Donghyuck's hands always found their way to his waist when they were cuddling on the couch, how he'd press up against Mark's back while they were cooking and slide his fingers across his stomach. It should have been obvious, really, but Mark had been too caught up in the casual intimacy of it all to notice the intent behind Donghyuck's actions.
"You're fucking insane," Mark says again, but his voice comes out breathy and weak. His cock throbs where it's trapped against his stomach, precome beading at the tip. "Did you just—what, sit around thinking about knocking me up?"
Donghyuck's grip tightens, making Mark gasp. "Not just that." His voice is rough, almost dangerous. "Thought about how you'd look. How desperate you'd get for it." His thumb swipes over the head of Mark's cock, spreading the wetness there. "Knew you'd be into it too. The way you always get so fucked out when I come inside you, how you never want me to pull out after." He presses his lips to the back of Mark's neck, teeth grazing the sensitive skin. "You're not exactly subtle, baby."
The words hit Mark like a punch to the gut. He can't deny it—not when his body's already responding so eagerly to Donghyuck's touch, not when he can feel himself getting hard again just from the memory of last night. His face burns as he realizes just how transparent he must have been, how obvious his reactions were every time Donghyuck finished inside him.
"It's not—" Mark breaks off, frustrated. His fingers twist in the sheets as he tries to gather his thoughts. "I didn't know I wanted it. Not until you started saying all that shit last night."
Donghyuck's hand slides up to cup Mark's jaw, turning his head so their eyes meet. There's something intense in his gaze that makes Mark's breath catch. "But you do want it now?"
Mark's face burns hotter, if that's even possible. "Yeah," he admits quietly. "Fuck, I don't know why, but—yeah. I do."
The confession hangs between them for a moment, heavy with implications. Then Donghyuck's kissing him, deep and filthy, swallowing the soft noise Mark makes. When they break apart, Donghyuck's pupils are blown wide, his breathing unsteady. "You have no fucking idea what you do to me," he growls, and Mark can feel how hard he is where he's pressed against his back. "The way you just—fuck, the way you just give yourself to me like this."
"You're making it weird," Mark mumbles, but his cock's already hardening again, body responding eagerly to Donghyuck's words. He shifts his hips back experimentally, feeling the way Donghyuck's length slides against him.
Donghyuck's hands find Mark's hips, steadying him as he grinds forward. "Careful, baby. You're still sensitive from last night." His voice drops lower, rougher. "Unless that's what you want? Want me to fuck you while you're still sore and messy?"
Mark's face burns at the words, but he can't deny the way his cock twitches, the way his hole clenches at the thought. "Maybe," he breathes out, pushing back against Donghyuck more insistently. "Want you to—fuck, want you inside me again."
Donghyuck groans, pressing his forehead between Mark's shoulder blades. His cock slides against Mark's ass, catching on his rim. "Shit, you're still wet from last night." His fingers dig harder into Mark's hips, holding him still. "Think you can take me like this? Without prep?"
Mark nods frantically, already trying to push back against Donghyuck's length. His mind's going fuzzy with want, thoughts scattered by the feeling of Donghyuck's cock pressing against him. "Please, I can take it, want it like this—"
Donghyuck cuts him off with a sharp thrust forward, sliding in almost too easily. Mark gasps at the stretch, at the way his body yields so readily. He's still loose from last night, still slick with Donghyuck's come, and the thought makes his cock throb where it hangs heavy between his legs.
"Fuck, look at you," Donghyuck breathes out, bottoming out in one smooth motion. His hand slides around to press against Mark's stomach again, possessive and firm. "Taking me so well, like you were made for it. Made to be filled up with my come."
Mark's legs shake as he tries to spread them wider, to give Donghyuck more room to work with. His mouth falls open on a silent moan when Donghyuck starts moving, the drag of his cock against Mark's walls almost too much after last night. "Fuck, Hyuck—"
"You feel so good like this," Donghyuck pants against his neck, hips snapping forward in a steady rhythm. "All loose and wet for me, taking me so deep." His hand presses down harder on Mark's stomach, making him whimper. "Can you feel it? Feel how deep I am?"
Mark nods frantically, unable to form words as Donghyuck fucks into him harder. His cock leaks steadily against the sheets, untouched and throbbing. He feels split open, used in the best way possible, and his mind goes fuzzy around the edges when Donghyuck's next thrust hits his prostate dead-on.
Mark's mouth falls open on a broken moan as Donghyuck starts grinding against his prostate in slow, torturous circles. The stretch is almost too much after last night, but his body's already adjusting, already wanting more.
His thighs quiver with the effort of staying spread, muscles burning as Donghyuck hooks an hand under his knee and lifts his leg higher. The new angle makes Mark's breath catch in his throat, forces him to grip the sheets tighter as Donghyuck's cock drags against his walls with each careful thrust.
Mark's mind goes blank for a moment as Donghyuck starts fucking into him with renewed intensity, the force of his thrusts pushing Mark further up the bed. His legs tremble with the effort of staying spread, muscles burning as Donghyuck holds him open. He can feel himself getting close already, cock leaking steadily against his stomach as Donghyuck's length drags against his prostate with each careful thrust.
"So fucking good for me," Donghyuck pants against his neck, hips snapping forward in a brutal rhythm that has Mark seeing stars. His hand slides down to press against Mark's stomach again. "Taking me so deep, aren't you? Bet you can feel me right here." His fingers press down slightly, making Mark whimper.
Mark's arm comes up to cover his face as he lets out a breathless whine, thighs trembling with the effort of staying spread. Donghyuck's cock drags against his prostate with each careful thrust, sending sparks of pleasure up his spine. He's close already—has been since Donghyuck first pressed inside him—and he can feel his orgasm building at the base of his spine.
Mark's hand snakes between his legs to wrap around his cock, desperate for some relief. His fingers are clumsy and uncoordinated as he strokes himself, overwhelmed by the dual sensation of Donghyuck's cock dragging against his prostate and his own hand working over his length. "Fuck, Hyuck, I'm gonna—"
"Yeah?" Donghyuck's voice comes out strained, like he's barely holding himself together. His hips stutter forward, rhythm faltering as he watches Mark fall apart beneath him. "Want you to come for me, wanna feel you get tight around my cock when you do."
Mark whimpers, hand speeding up on his cock as Donghyuck's words wash over him. His mind goes fuzzy around the edges, thoughts scattered by the overwhelming pleasure building in his gut. Every thrust has him seeing stars. He's close—so fucking close—and he can barely breathe through it, can barely focus on anything except the feeling of Donghyuck inside him and his own hand working desperately over his length.
"Come on," Donghyuck urges, voice rough with want. His fingers dig harder into Mark's hip as he fucks into him faster, deeper. "Know you're close, can feel how tight you're getting. Wanna feel you come on my cock, baby, want you to milk every drop out of me—"
Mark's orgasm hits him like a freight train, vision whiting out as he spills over his fingers with a broken cry. His body locks up, hole clenching rhythmically around Donghyuck's length as pleasure crashes through him in waves.
Donghyuck fucks him through it, hips snapping forward in short, desperate thrusts as Mark shakes beneath him. His fingers press harder against Mark's stomach, possessive and demanding as he chases his own release. "Fuck, you feel so good," he pants, voice strained. "So fucking perfect for me, taking me so deep—"
Mark whimpers at the oversensitivity, body trembling as Donghyuck keeps fucking into him. His mind's gone hazy with pleasure, thoughts scattered by the feeling of Donghyuck's cock dragging against his walls. He can barely form words, can barely do anything except lie there and take it as Donghyuck uses him.
"Please," he manages to gasp out, though he's not sure what he's asking for. His fingers twist in the sheets as Donghyuck's thrusts grow more erratic, more desperate. "Want you to come inside me, want to feel it—"
Donghyuck groans, hips stuttering forward as he buries himself deep inside Mark. His fingers dig harder into Mark's hip, hard enough to leave bruises as he starts to come. Mark gasps at the feeling of being filled up again, at the way Donghyuck's cock pulses inside him.
"Fuck," Donghyuck breathes out, pressing his forehead between Mark's shoulder blades as he comes down from his high. "You're fucking incredible, you know that?"
Mark shivers at the praise, too fucked out to form a proper response. His body feels heavy and loose, pleasure still thrumming under his skin as Donghyuck’s cock softens inside him. He knows they should clean up—knows they’ll regret it if they don’t—but he can’t bring himself to move just yet.
"We should shower," Donghyuck says after a moment, but he makes no move to pull out. His hand stays pressed against Mark’s stomach, fingers tracing idle patterns across the skin. "Don’t want you getting sore."
"Already sore," Mark mumbles. He shifts slightly, feeling the way Donghyuck’s come starts to leak out of him when he moves. "Fuck, I can feel it dripping—"
Donghyuck’s cock gives an interested twitch at that, making Mark gasp. "Don’t," he warns, reaching back to swat at Donghyuck’s thigh. "I actually won’t be able to walk if we go again."
"Fine," Donghyuck sighs, finally pulling out with a wet sound that makes Mark’s face burn. He presses a kiss to Mark’s shoulder, gentle and sweet. "Shower first, then we can talk about round three."
Mark groans, burying his face in the pillow. "You’re actually trying to kill me."
"Only a little," Donghyuck says, and Mark can hear the grin in his voice. He shifts away from Mark, the bed dipping as he moves. "Come on, up you get. The sooner we shower, the sooner we can get back to bed."
Mark lets himself be pulled up, legs shaky as Donghyuck guides him toward the bathroom. His mind’s still fuzzy around the edges, thoughts scattered and unfocused. He knows they should probably talk about this—about what it means, about how things might change—but for now, he’s content to let Donghyuck take care of him.
Mark doesn't bring it up until two days later, when they're lying in bed after another round that left his thighs trembling and his mind pleasantly blank. He's curled up against Donghyuck's side, tracing mindless patterns across his chest as he tries to find the right words.
"So," he starts, voice still a little hoarse. "The whole...breeding thing."
Donghyuck tenses slightly beneath him. "What about it?"
"You really get off on that, don't you?" Mark keeps his eyes fixed on his own fingers, watching them move across Donghyuck's skin. "The idea of getting me pregnant or whatever."
"I—fuck." Donghyuck's hand comes up to run through his hair, a nervous gesture Mark's familiar with by now. "Yeah, I guess I do. Is that weird?"
Mark shakes his head, shifting closer. "Not weird. Just...different." He pauses, considering his next words carefully. "I like it too, you know. The way you get when you're like that."
Donghyuck's breath catches audibly. "Yeah?"
"Yeah." Mark's face burns, but he forces himself to continue. "Like how possessive you get, and the things you say, and—fuck, the way you press down on my stomach when you're inside me." His cock gives an interested twitch at the memory, making him flush harder.
Donghyuck's fingers flex against Mark's hip, thoughtful. "So you've been thinking about it too?" His voice drops lower, rougher around the edges. "About me getting you pregnant?"
"Been hard not to think about it," Mark admits, face burning. His fingers curl against Donghyuck's chest, restless. "Especially when you get all intense about it, talking about filling me up and keeping me bred."
Donghyuck exhales sharply, grip tightening. "Fuck, the way you say that." He shifts slightly, pulling Mark closer against him. "Never thought you'd actually be into it. Thought it was just something you put up with because I got carried away during sex."
"No, I—" Mark breaks off, frustrated by his inability to find the right words. "It's not just that. I like how desperate you get, how much you want it. Makes me feel wanted." He pauses, gathering his courage.
"And I like—" Mark hesitates, fingers curling against Donghyuck's chest. "I like the idea of belonging to you like that. Of being yours in every way possible." His voice drops to barely above a whisper. "Even if we both know it's impossible, the thought of you actually getting me pregnant is just—fuck."
"God, Mark." Donghyuck's voice comes out rough, almost desperate. "The things you do to me." His hand slides down to press against Mark's stomach, making him shiver.
"Why did it start?" Mark asks after a moment, voice quiet in the darkness of their room. His fingers trace absent patterns over Donghyuck's ribs, mapping out the spaces between them.
Donghyuck hums in thought, shifting slightly beneath Mark's touch. His hand stays pressed against Mark's stomach, warm and steady. "You were wearing one of my shirts during practice, and it was just—fuck. Something about seeing you in my clothes, all soft and pliant after rehearsal. Made me want to take you home and fill you up."
"That's not all of it though, is it?" Mark pushes himself up on one elbow to look at Donghyuck properly, studying his face in the dim light filtering through the curtains. "You've seen me in your clothes before."
Donghyuck's fingers flex against Mark's skin, considering. "No, it's not all of it." He pauses, like he's weighing his next words carefully. Donghyuck lets out a long breath, his free hand coming up to cover his eyes. "Fuck, okay. Remember that night we went out with the others? When Jaemin wouldn't shut up about his new apartment?"
Mark nods slowly, trying to piece together where this is going. "Yeah, what about it?"
"You were drunk as shit, and you started talking about how much you wanted kids someday." Donghyuck's voice comes out rough, almost embarrassed. "Said you'd be such a good dad, that you couldn't wait to have a family. And then you looked at me and said—" He cuts himself off, swallowing hard.
"What did I say?" Mark asks, even though his stomach's already doing flips. He has absolutely no memory of this conversation.
"You said you wished I could give you kids," Donghyuck finishes quietly. "That you wanted them to have my smile or some shit like that. And then you passed out on my shoulder before I could even process what you'd said."
"Oh." Mark feels his face heat up, warmth spreading down his neck. "Fuck, I really said that?"
"Yeah, you did." Donghyuck's hand slides up to rest on Mark's waist, steadying. "Couldn't stop thinking about it after that. About you wanting that with me. And then seeing you with Jisung's cousin just made it worse. The way you held her, how natural you looked with a kid in your arms—it did something to me."
Mark feels his face heat up at the admission. "So that's why you were so intense that night." He remembers how Donghyuck had barely let him through the door before pressing him up against the wall, hands desperate and wanting as they stripped him bare.
"Yeah, well." Donghyuck's voice comes out rough, almost defensive. "You can't blame me for getting carried away. You were fucking gorgeous like that, all soft and gentle with her. Couldn't stop thinking about what you'd look like with our own kid."
Mark's breath catches in his throat at the possessiveness in Donghyuck's tone. "You really think about that? About us having kids together?"
"Sometimes," Donghyuck admits, fingers tracing idle patterns across Mark's stomach. "Know it's impossible, but. Yeah. Think about it more than I probably should."
Mark shifts closer, pressing his face into Donghyuck's neck. "It's not weird," he murmurs against the skin there.
"Like, thinking about having a family with you one day isn't weird." He presses a kiss to Donghyuck's collarbone, gentle. "Even if this specific thing started because of it."
"Yeah?" Donghyuck's voice comes out softer than usual, almost vulnerable. His fingers trace up Mark's spine, settling between his shoulder blades. "You still want that? Kids and shit?"
Mark nods against his neck. "Course I do. Always have." He shifts slightly, propping himself up on one elbow to look at Donghyuck properly. "Didn't think you'd want the same thing though. You never really talked about it before."
Donghyuck's quiet for a moment, fingers still moving absently against Mark's skin. "Didn't want to freak you out," he admits finally. "We've only been together for what, eight months? Figured it was too soon to start talking about kids and marriage and all that shit."
"Eight months isn't that soon," Mark argues, but his heart's racing at the casual mention of marriage. "Not when we've known each other for so fucking long. Not when I've been in love with you since before I even knew what that meant."
Donghyuck inhales sharply, his hand stilling on Mark's back. "You can't just say shit like that." His voice comes out strained, like he's trying to keep himself together. "Not when you're lying here all fucked out and pretty, talking about wanting a family with me."
"Why not?" Mark pushes, because he's always been a little reckless when it comes to Donghyuck. His fingers trace the line of Donghyuck's jaw, feeling the way his pulse jumps beneath the skin. "S'not like you don't know how I feel about you. Not like we haven't been dancing around this for years."
"Mark," Donghyuck says, and it sounds like a warning. His fingers dig into Mark's hip, possessive and grounding. "I'm trying really fucking hard not to kiss you right now."
"Then don't try." Mark shifts closer, pressing their foreheads together. His heart's beating so fast he's sure Donghyuck can feel it. "Kiss me. Talk to me about wanting kids with me. Tell me you want the same things I do."
Donghyuck makes a broken sound in the back of his throat before surging forward to capture Mark's lips in a bruising kiss. It's messy and desperate, all teeth and tongue as Donghyuck rolls them over to pin Mark beneath him. "Fuck, of course I want the same things," he breathes against Mark's mouth, hands sliding down to grip his thighs. "Want everything with you. Want to give you everything."
"Then do it." Mark arches up into him, wrapping his legs around Donghyuck's waist. "Show me how much you want it. How much you want me."
Donghyuck groans, pressing Mark deeper into the mattress. "You're gonna be the fucking death of me, you know that?" His hands slide up Mark's sides, possessive and wanting. "Always saying shit that makes me lose my mind."
"Only for you," Mark breathes out, and he means it more than anything. His fingers tangle in Donghyuck's hair, pulling him down for another kiss. "Always for you."
