Chapter Text
Clark couldn’t sleep.
Restlessness thrummed through his body, his skin stretched too tight, his pulse beating too fast. Five months along and his hormones were relentless—every brush of fabric, every stray thought of his husband left him aching with want. His desire had turned feral, leaving him embarrassed at times, desperate at others.
Lex had always been attractive and irresistible, but pregnancy seemed to have rewired Clark’s senses, magnifying his hunger until it was unbearable.
Sometimes he is worried. What if his swollen belly dulled Lex’s desire? What if what Clark felt as an unbearable need was only awkwardness for his husband?
But tonight, none of that mattered. Tonight, he needed Lex.
He shifted closer, pressing his forehead against Lex’s shoulder, whispering into the warmth of his skin. “Lex,” he breathed, tugging gently at his husband’s arm. “I’m sorry. Please, wake up. I need you.”
Lex stirred, rubbing at his eyes, still heavy with sleep. Before he could even ask what was wrong, Clark’s mouth found his—hot, needy, desperate. The kiss stole the air from both of them, Clark pouring his restless hunger into every press of his lips.
Lex’s hands found Clark’s waist instinctively, grounding him with careful pressure. Clark let out a low, trembling sound as his husband guided him, steady and sure, until he was straddling his lap. The shift pressed them close, heat against heat, Clark’s body shaking as he clung to him.
For a moment, Lex simply held him there, thumbs brushing soothing circles into his hips, steadying the storm.
“Clark,” he murmured against his lips, voice still rough from sleep. “Slow down, baby. I’ve got you.”
Clark only kissed him harder, like the words weren’t enough, like reassurance meant nothing without touch.
He pulled back only long enough to shove his pajama top off his shoulders, eyes glazed, pupils blown wide with need. His breath came in ragged bursts as he looked at Lex like a man unraveling. “This is your fault,” he gasped, chest heaving. “I’m so horny and so big and heavy all the time.”
Lex’s mouth curved into a slow, knowing smile. He didn’t bother denying it. He loved every change in Clark, every sign of the life they’d created together. He reached out, palms sliding reverently over the swell of his chest, his sides, the fullness of him.
“I know, baby. But I’m not sorry.” His thumbs traced tender circles over flushed skin, making Clark shiver. “I’ve never wanted you more.”
His hands mapped Clark’s body, lingering over soft, swollen curves. He pressed open-mouthed kisses along Clark’s throat, stopping to taste the frantic pulse there until Clark shuddered against him. Then Lex’s mouth wandered lower, teeth grazing lightly, drawing helpless moans.
Clark gasped when Lex’s thumbs circled his nipples, feather-light at first, then pressing harder, tugging until Clark arched into his hands. Lex lowered his mouth, sucking one into his lips with a wet pull, teeth grazing just enough to make Clark’s breath stutter.
“Oh, Lex please” Clark whined, hips rocking helplessly against his thigh. Lex hummed around him, the sound reverberating through Clark’s chest, down his spine. He switched sides, tongue flicking over the other nipple before sucking deep and slow, while his fingers pinched and rolled the one he’d just abandoned. Every motion was deliberate, equal, and unrelenting.
“God,” Lex groaned against his chest, licking like he couldn’t get enough. “You’re so sensitive now. Look at you shaking already. Bet I could make you come from this alone.”
Clark let out a broken sound, half sob half moan, grinding harder against his husband’s thigh. Every tug, every suck, sent sparks racing through him.
“Please,” Clark gasped, voice trembling. “I need—”
“Patience, love.” Lex’s smirk curved against his skin before he bit gently at the stiff peak, making Clark jolt. “Let me play with you. Let me hear you.”
Clark clung to his shoulders, desperation threading through every breath. “No Lex, I need you now please.”
“Yes, you can,” Lex soothed, before closing his mouth over Clark’s nipple again, drawing a sharp cry from his lips.
Clark moaned, body bowing helplessly under the waves of sensation.
“You’re dripping for me, aren’t you?” Lex rasped, tugging gently while his mouth drew another wet pull. “So wet I don’t even need to touch you down there. I could make you fall apart right here.”
Clark’s hips rocked harder, his voice breaking into sobbing moans. “Lex, please—”
“Do it for me, baby,” Lex coaxed, sucking hard, pinching just right. “Come for me. Come just from my mouth on you. Show me how good I make you feel.”
The words tipped him over. Clark cried out, body seizing with release, grinding helplessly against him as wave after wave of pleasure tore through him.
Lex held him steady, still teasing his swollen peaks with tongue and teeth until Clark was gasping, oversensitive, and clinging desperately to him. Clark sagged against his neck, trembling, breath coming in shallow bursts as the last waves of his orgasm faded. Lex stroked his back, then tipped his chin so their eyes met.
“Love,” he murmured, lips brushing Clark’s temple, “don’t drift off on me yet. I’m not done with you.”
Before Clark could answer, Lex’s mouth was on his throat again, leaving hot, lingering kisses and sharp little nips that made him moan. His hands slid lower, tugging his pajama pants away, leaving him bare and trembling from oversensitivity.
Clark whimpered when Lex’s fingers slipped between his thighs, finding his clit circling with practiced precision. Fresh sparks of pleasure shot through him, too much after what he’d already had, but Lex always knew. He knew Clark craved the dizzying rush of being pushed further.
“You’re already soaked for me,” Lex whispered against his skin, fingers sinking deeper, stretching him with a rhythm that had Clark squirming helplessly in his lap.
Clark’s broken moans filled the room, hips grinding down against his hand, caught between pleading for mercy and begging for more.
Lex pulled his fingers away only long enough to shove his own boxers down, his cock springing free, thick and hard. He lined himself up and eased inside slowly, inch by inch, groaning as Clark clenched around him.
They both moaned, foreheads pressed together, lips brushing, breathing each other in as the stretch gave way to fullness.
“Gosh,” Clark gasped, clutching at Lex’s shoulders.
“Shh,” Lex soothed, kissing him deeply as he began to thrust upward in steady, measured strokes. Each push drew a cry from Clark’s lips, each drag set his body alight. Their mouths found each other again and again, messy, desperate, hands roaming everywhere. Clark gripped Lex’s arms, Lex’s palms slid reverently over his belly, over his chest, as if he couldn’t stop touching, couldn’t stop worshipping.
Lex pulled back just enough to look at him. Clark’s cheeks were flushed, his eyes glazed, his body trembling—pregnant, needy, and utterly his.
“Look at you,” Lex said, voice rough with awe. “Utterly undone. You’re so beautiful like this, pregnant with my child, trembling for me. God, I want to keep you like this forever. Always full of me. Always mine.”
Clark let out a strangled moan at the words, clinging tighter, his whole body shuddering as another climax built under Lex’s devotion.
Lex’s thrusts stayed deep and unhurried, each one pulling sharper cries from Clark’s throat. His husband’s body clenched around him so tightly, slick and pulsing, every movement threatening to undo them both.
Lex kissed him again, slow and messy, before pulling back to murmur against his lips. “That’s it, baby. Take me. You feel so good, so tight, so wet, even after I’ve already wrung you out once.”
His hand slid between their bodies, circling Clark’s clit in time with his thrusts. “You were made for me. For this.”
Clark sobbed, overwhelmed, hips rolling helplessly into every push. “Lex I can’t it’s too much—”
“You can,” Lex promised, low and reverent. “Look at you. Gorgeous, glowing, carrying our child and still desperate for me. You’re perfect, Clark. So fucking perfect.”
He thrust harder, angling until Clark broke apart in another orgasm, his body clamping down, cries spilling into Lex’s mouth as he kissed him through it.
But Lex didn’t stop.
“Again,” he whispered, still moving, still stroking. “I want to feel you come again. Please, baby, one last time.”
Clark shook his head, tears slipping from the corners of his eyes, the pleasure overwhelming. “I-I can’t please—too much”
“Yes, you can, baby. You always can for me. Look at you—pregnant, sobbing, milking me so tight. Fuck, you’re going to make me come just from how beautiful you are.” Lex kissed the tears from his cheeks, swallowing them like something sacred. His hand pressed over Clark’s belly, reverent, feeling the life growing between them.
“Carrying my baby,” he growled, voice breaking. “I’ll never let you be empty. I’ll keep you full, keep you pregnant, forever mine. That’s what you want, isn’t it?”
Clark arched into him, sobbing louder, overstimulated, and came undone again. The sound shredded Lex’s control.
“Fuck, I’m gonna come.” Lex gasped, burying his face against Clark’s wet cheek. He licked at the tears even as his hips snapped harder, desperate, and needy. Clark sobbed his name as Lex thrust one last time, spilling deep inside him. Lex held him tight, trembling, and kissing his tear-streaked face with worshipful reverence.
Clark slumped against his chest, trembling, cheeks flushed and wet. His breaths came in ragged pulls, and his body was utterly spent. Lex softened his thrusts until he stilled, holding Clark close, stroking his back in soothing circles. He kissed away the last of his tears, lingering tenderly.
Lex eased out slowly, kissing Clark’s lips in apology when he whimpered at the loss. He reached for a warm cloth, gentle as he cleaned him, and murmuring soft reassurances all the while.
When he was done, he tucked Clark beneath the blankets, sliding in beside him and pulling him close. He pressed a tender kiss to Clark’s temple, lingering there.
“I love you,” Clark whispered, voice hazy with sleep.
Lex’s chest ached with it. He kissed him again, his hand resting reverently on the swell of Clark’s belly. “I love you more. Both of you.”
