------------------------------------------------------------------------------
Jaehyun:
"I left the barracks. I'll be there in 40 minutes. Open the door when I knock. And wear something that drives me crazy. I want you as soon as I get in."
Nayara read the message with trembling fingers.
It was his birthday. But the one who was about to receive a gift was her.
Forty minutes later, the sound of the knock on the door froze her. Three firm knocks. She opened it without thinking. He was there.
In full uniform. Closed jacket. Hair shaved on the sides, heavy expression. But when he saw her, something in him softened. For a second, the soldier gave way to the man who spent nights dreaming about that moment.
He pulled her slowly. His arms wrapped around her waist and Nayara buried her face in his chest. The rough fabric of the uniform contrasted with the heat of the body underneath. He kissed the top of her head. Then, her face. Her forehead. Her nose.
And then her mouth.
It was a long kiss. Calm at first, but full of longing. His tongue found hers as if he were quenching his thirst. An old thirst. His body pressed against hers, his weight, his scent, everything about him dominated her effortlessly.
"You have no idea what went through my head in these six months," he whispered against her mouth. "And now that I'm here, you're mine. Whole. Without pause."
He rested his forehead against hers for a moment. His breath was warm. His hands running down Nayara's back, lightly squeezing her waist, her ass, as if he were confirming that it was real.
"Show me that you still know how to give me what's mine."
Nayara knelt down.
It was natural. Instinctive. The position her body asked for, the surrender her desire begged for.
He looked down, his eyes darkening with pleasure.
"Good girl."
Jaehyun slowly unbuckled his belt, without taking off his uniform. He opened his pants just enough and pulled out his cock, already hard, thick, throbbing. Nayara looked at him as she ran her tongue over his lips, then over the tip, slowly. She tasted him. Warm, familiar, intoxicating.
She wrapped her lips around it and began to suck.
Slowly at first, just her mouth working, exploring. He let out a muffled moan, his hand in her hair, guiding her movements.
"That's it… fuck. Like that…"
She increased the pace. Warm mouth, tongue circling, sucking harder. He threw his head back for a second. His hips began to move, thrusting deeper into her throat.
"Look at me," he ordered. Nayara obeyed, her eyes watering, but fixed on his.
He held her head steady. He began to fuck her mouth with slow, deep thrusts. His other hand went to her face, his thumb running over the corner of her mouth, wiping away the drool that was dripping down.
"Fuck, I missed this so much," he whispered, his voice hoarse. "You like this… on your knees, swallowing everything… like you were born for it."
Nayara moaned with him deep in her throat. He felt it. He freaked out. The pressure increased. His control was gone.
He was thrusting hard now, holding her head steady, fucking her mouth like it was the only way to relieve six months of accumulated tension.
But before he could cum, he stopped. He pulled Nayara back by her hair, her breathing ragged and her eyes wild.
"Turn around. Now. I want to fuck you with this uniform on my body. And with your mouth still dirty with me."
He pulled Nayara by her hair with calculated strength, her breathing still heavy from what it almost was. Her eyes wild, hungry.
He guided her to the sofa with firm steps, without taking his eyes off the body he had desired for six months.
He threw her there as if she were his — and she was.
“On all fours,” he ordered. “Cross your legs.”
She obeyed without hesitation. Leaning on her elbows, with her knees together and her legs crossed, just like he wanted. The position made her even tighter, more sensitive. And he knew it. Fuck, how he knew.
Jaehyun knelt behind her. His uniform still intact, his boots firmly on the floor. Nayara heard the sound of his pants opening further, his breathing heavy… and then — his tongue.
Without warning.
He dove between her legs like an animal on the loose. His tongue licked, entered, circled violently. Without subtlety. Without care. He ate her with his mouth as if he were trying to destroy every trace of longing that remained between them.
“Stay like this,” he growled against her flesh. “So tight, just the way I like it.” His hands spread her buttocks forcefully, exposing everything. Nayara moaned loudly. He just stuck his tongue deeper. And sucked. He sucked as if he was addicted to her. As if he wanted to make her cum just to see her trembling for him.
When she squirmed too much, he held her tight. He bit her. He gave her ass quick slaps. He made sure to keep her there, crossed, vulnerable, completely exposed.
"Are you going to cum like this? Just with my tongue? Six months and it's still this easy?"
Nayara could barely answer. She just moaned, gasped, begged.
"Tell me. Tell me it's my pussy. That no one else has touched."
"It's yours… only yours, Jaehyun… it always has been!"
He sucked harder. His tongue vibrated on her clit with rhythm and pressure, his fingers sliding inside, filling her and fucking her along with his mouth.
And Nayara exploded.
The orgasm came tearing through her. Strong. Hot. Almost painful. She screamed, her whole body shaking, her crossed legs tightening instinctively.
But he didn't stop.
He kept licking, sucking, fucking her with his fingers. He wanted more. He wanted to see her cum again. He wanted to leave her out of control, lost, torn to pieces.
And when she tried to run away, he just pulled Nayara back by the waist.
"Don't run away. I've waited six months. You'll handle it all."
She was still shaking from the orgasm, her body arched, her legs crossed as he'd told her to. But Jaehyun wasn't even close to satisfied.
He stood up, wiping his mouth with the back of his hand, his gaze full of fire.
"Stay like that."
Without breaking the mood, he opened his pants further, without taking anything off. He just left his cock free, hard, throbbing. His uniform hung open, but he was still wearing everything—and that only made everything dirtier.
He spat on his hand, spread it around his base, and knelt behind her.
With one hand firmly on Nayara's waist and the other on her braids, he pulled her head back as the tip of his cock touched her hot, throbbing entrance.
"I'm going to fuck you until you forget your name."
And he did.
Deep. All at once. Without mercy.
She screamed. The sound was muffled by his hand that covered her mouth next.
"Shhh… you're going to wake the neighbors. Or do you want everyone to know that you're being fucked by your man in uniform, on the couch?"
The thrusts came hard, heavy. He pounded his entire body, each movement making the couch creak. His hand held Nayara's hips, pulling her against his thrusts brutally. The sound of their bodies colliding was loud, wet, animalistic.
— You're mine. Mine. Do you understand?
— Yes, fuck, only yours!
He pulled her braids hard, bending her spine, making Nayara look back while he fucked her. His eyes were wild. His uniform was sweaty. His face was red with tension.
He spat on her ass, ran his finger, threatened to put it in.
— You can handle it, right? You like it when I'm like this. Rough. No mercy.
And she moaned even more. She begged. She pleaded.
He threw her sideways on the couch, lifted one leg on his shoulder and thrust again. The new angle made him hit her hard. Nayara felt everything. And he moaned along with her — low, hoarse, as if he was fighting himself.
— You're going to cum again for me — he growled. — Now. Come with me.
And she came.
The second time was even stronger. Her body locked up, her chest heaving, her legs shaking.
Jaehyun thrust a few more times, his movements becoming uncoordinated. He grunted deeply, dug his nails into her skin and came hard — deep inside, with her entire body trembling on top of his.
The silence afterward was heavy. They were both panting. Sweaty. Exhausted.
But he hadn't taken off his uniform yet. And Nayara knew: it wasn't going to stop there.
Without needing to say anything, he fell on top of her, his sweaty chest pressed against Nayara's back. Their bodies were still pulsating, shaking. His uniform stuck to their skin — and the heat between them seemed to set the room on fire.
She turned her face and smiled, with that glint of challenge in her eyes.
"First round… and you're already like this?"
He laughed. That low, hoarse laugh that made the hairs on her body stand on end.
“You don’t know what I brought in my backpack.”
And then the second round began…
She turned her face and smiled, with that glint of challenge in her eyes.
“First round… and you’re already like this?”
He laughed. That low, hoarse laugh that made the hairs on her body stand on end.
“You don’t know what I brought in my backpack.”
Still panting, he got up from the couch. He slowly took off his jacket, then his t-shirt. His body was pure muscle and training marks—thick thighs, tense arms, sweat running down between the abs. Nayara watched him silently, biting her lip.
Without rushing, Jaehyun crouched down next to the backpack thrown on the floor and opened it. He took out two items: a small, discreet vibrator and a thick, black cock ring. He left them on the couch as if he knew exactly what he was going to do with each one.
“I thought about you every time I jerked off,” he said directly, his voice deep. “And I bought this thinking about when I came back. Now that I’m here… you’re going to feel everything.”
Nayara was already lying down again, her legs spread, her body alert, her breathing lighter — but full of expectation. Her wide thighs shone with desire, her pussy still wet, throbbing.
“Come on, then. Show me.”
Jaehyun didn’t need more. He knelt between her legs and, with his eyes fixed on hers, put the ring on the base of his cock, which was already half erect — but began to harden completely just looking at Nayara there, open, surrendered.
He turned on the vibrator. He first touched the inside of her thighs. Nayara shivered all over. She moaned softly, instinctively.
— Not directly on the clitoris… Jaehyun…
— Shhh. Now it's my way.
Firmly, he slid the vibrator to the center, circling her clitoris with slow and continuous pressure. His fingers began to slide inside, slowly, feeling how hot and ready she was. Nayara was moaning loudly now, her whole body responding to each touch. The vibrator was vibrating in the exact spot. He knew what he was doing.
She came again. A lighter orgasm, more sensitive, but still hot and pulsating. Her body writhed beneath him. Jaehyun smiled, climbed on top of her, fitted his cock between her legs and thrust slowly — with the ring vibrating along with it, intensifying each sensation.
— Fuck, Nayara… you squeeze me in a way…
They moaned together now. The rhythm was more controlled, the movements precise, but the pleasure multiplied. The ring vibrated at the base. The vibrator still teased her clitoris. And Nayara was already at her limit again.
“Get on top,” he asked, his voice choked, as if he couldn’t take it anymore.
She rode him firmly, her hands on his chest, shaking her hips hard. Her ass slapped against his thighs with dry pops. The vibrator, now stuck between them, was still on, and he almost screamed with the double stimulation.
“Go on… Nay… fuck me like that. That’s it, fuck!”
She leaned forward and bit his shoulder. Her nails scratched his abdomen. They were both sweaty, glued together, wild. Their bodies fit together perfectly.
And then, finally, they came together.
Trembling. No sound. Just ragged breathing, eyes closed, bodies collapsing.
Silence.
Then, only the click of the vibrator being turned off… and her muffled laughter, pressed against his ear.
Nayara got off the couch, limping slightly. Her legs were shaking. Her skin was still vibrating. She was walking towards the bathroom, trying to find some balance, when she felt the weight of his gaze.
She turned slowly.
Jaehyun was still lying on the couch, his chest rising and falling slowly, his muscles relaxed, but his eyes fixed on her — hungry.
His body seemed exhausted… but his cock was still hard, erect between his thighs, as if saying everything he didn't have the strength to say yet.
She arched an eyebrow.
"Are you going again?"
He didn't answer. He took a step. Then another. Until his body was pressed against hers. Without hesitation, he ran his hand over her face, then down her throat, until he held the back of her neck firmly.
"Shut up and lie down on the bed. Legs open. Hands up."
His voice left no room for discussion. It wasn't a suggestion. It was a command.
Nayara's body reacted before her mind. She turned over without saying anything, the air already starting to heat up again. She climbed onto the bed, lay down in the center of the mattress, and did exactly what he told her to do. Her body was limp, exhausted, but her desire was reignited like a fire on damp wood. Her thighs were throbbing. Her pussy was starting to throb with just the anticipation.
Jaehyun came in right after. The same look as before — focused, hungry, full of possession. He brought the vibrator out again. And something else: a Velcro handcuff that she didn't even know he had brought with him.
"I want you to surrender, Nay. No escape. You'll cum until you beg me to stop." She smiled mischievously. Defiant, even when she was on edge.
"I doubt it."
Jaehyun climbed onto the bed slowly. He pinned her wrists together, above her head, using the headboard as support. He turned on the vibrator and placed it between her legs — without touching her clitoris directly, just teasing, prodding the edges of desperation.
Meanwhile, he masturbated slowly. His cock grew once more. Firm. Throbbing. His jaw clenched. His chest heaving as if he already anticipated what was coming.
—Look how my cock gets just seeing your pussy open.
She moaned. Her legs tried to close reflexively, but he used his knee to force them open. More. And more.
And then, he thrust.
All at once. Without warning. Without relief. Without time to breathe.
She screamed, her body arching. He thrust deep, hard. The vibrator was still stuck between them, pressing against her clitoris with each thrust. The cock ring still vibrated at the base, keeping it rigid. Intensifying everything.
Her eyes rolled back.
— DON'T STOP, JAEEEH—
He covered her mouth with his big, warm hand.
— Shhh. I'm far from stopping.
He pulled out and put it back in again. He pulled out slowly, then went back in with everything. Deeper. Faster. Nayara screamed through her eyes, her whole body trying to escape and beg at the same time. But he kept her there. Surrendered. Completely surrendered.
Her hands tied. Her soul wide open.
He bit her shoulder. He slapped her ass, pulled her hair, cursed softly with a choked voice.
— Holy shit… you were born for this. To be fucked by me. All over. Until you passed out.
And she came.
Hardly. Almost painfully. Her whole body trembled. . And he kept going. Relentless.
She couldn't speak anymore. Her hands were numb, her arms pinned above her head, her body sweaty, vibrating, begging for the end and for more at the same time.
Jaehyun thrust like a man on the edge of control. His thrusts hit deep, more intense and desperate. The vibrator was still vibrating between them. And Nayara was crying.
Tears streamed from her eyes — not from pain, but from overwhelming pleasure. Pleasure that her body didn't know how to contain.
And he saw it.
"Are you crying for me, love?" he whispered, his voice cracking with lust. "You're feeling everything, right? You're squeezing me so tight… fuck…"
His cock was throbbing. Nayara was wrapping herself around him so tightly that he could barely move.
"You're going to make me cum inside you. You want it, right? You want me to explode inside you."
All she could do was moan and shake her head, her face sweaty, her eyes wet.
That's when he bit down.
With his hand firmly holding her hip, he bent over and bit her shoulder hard — marking it, as if he wanted her to remember that moment for the rest of her life.
And then he came.
Jaehyun locked his entire body. A hoarse grunt came from his throat. His cock exploded inside her in hot, strong, endless jets. He came deep, feeling Nayara tighten even more with each contraction, as if her body was sucking every drop.
"That's it… fuck, Nayara… swallow it all… everything… fuck…"
The hot jets hitting the bottom. The heat invading. Her thighs trembling. Her body collapsing along with his.
He stayed inside her for a few seconds, still pulsing, still moaning softly in her ear. Their bodies stuck together, wet, panting.
When he finally pulled out, his cock slipped out slowly, glistening with cum. He saw it — cum began to leak out of her, white, thick, hot, staining the sheets between her legs.
And he didn't accept it.
—No… no. This is yours.
With his fingers, he tried to push it all back in. Gently, but obsessively. As if it were more than just cum — as if it was part of him that he didn't want to escape.
Nayara moaned as she felt his touch, trying to hold back the cum.
— Stay with me — he murmured, looking straight into her eyes.
And then, he bent down and kissed her.
A slow, wet kiss
He let go of her hands. But Nayara didn't move.
She stayed there. Lying down. Destroyed
Jaehyun hugged her from behind, still on the bed.
— I love you so much, Nay.
She smiled, her eyes closed and her soul satisfied.
— Happy birthday, Jaehyun.
The room fell silent.
Just the sound of the fan spinning on the ceiling and her breathing slowing down little by little. Nayara still lying on her side, legs half open, her entire body relaxed and sensitive, her skin crawling where he hadn't even touched.
Jaehyun knelt beside the bed, his head resting on the mattress. He observed her body as if he couldn't believe she was real.
He got up slowly, went to the bathroom, wet a towel with warm water and came back.
“Stay still, love,” he said softly.
She didn’t answer. She only let out a sigh when she felt the warm touch between her legs.
Jaehyun cleaned her carefully. With reverence. He wiped the towel slowly, removing the traces of cum with care, without pressing. As if he were taking care of the most precious thing in the world. Every now and then, he gave her a kiss on her thigh. Or on her belly.
When he was done, he threw the towel in the basket and came back with one of his t-shirts. He dressed Nayara delicately, as if she were made of glass.
“Are you hungry?” he asked, fixing her hair with his fingers.
“Only you,” she murmured, with a lazy smile.
He laughed, but still took out his cell phone and ordered food. Then he lay down behind her, wrapping his arms around her waist, his nose touching her neck.
They stayed like that. Glued together. In silence. His touch was different now — light, soft. A finger tracing invisible lines on her arm. A kiss on the back of her neck every minute.
“You drive me completely crazy, you know?” he said, his voice low. “When I was there… in the barracks… the only thing that kept me going was imagining you. Here. Waiting for me.”
She squeezed his hand between her fingers, her eyes still closed.
“And you came back. And you fucked me like the world was ending.”
“And after that, I just want to take care of you,” he whispered. “To bathe you, to feed you, to hold you in my arms. You are my love and my addiction.”
He kissed her shoulder. His breathing was already slower. And even so, his touch remained. Endless affection.
Jaehyun was no longer the soldier who arrived breaking everything. Now he was just the man. The boyfriend who cleaned. Cared. Loved.
A short time later, the intercom rang.
Jaehyun got up slowly, still naked, put on a pair of random shorts and went to the door to get the order. Nayara stayed in bed, lying on her side, just watching.
When he came back, he was carrying a tray with food and two glasses of juice. He balanced everything with that smile of someone who is completely surrendered.
"Time to replenish your energy, Mrs. Jeong," he said, blinking.
She laughed, sitting up with effort on the bed. His shirt was still half-up, his legs spread, red marks on his thighs. He helped her adjust the pillows, placed the tray on her lap, and sat next to her, close.
"You knew that fucking me like that would leave me without the strength to get up, right?"
"I knew. That was the plan," he said, laughing.
They ate slowly, sharing the food with each smile. With each bite, he made sure to put it in her mouth, as part of the care. She returned his gaze with warm glances, but the mood was different now — calm, intimate, almost sacred.
When they finished, he gathered everything up, left it in the kitchen and went back to the bedroom. Nayara was already lying down again, with her eyes closed. But she opened them when she felt his arms wrap around her legs.
“What’s up…?”
“You’re going to take a shower. And I’m going to take you.”
“You’re crazy.”
“Crazy about you.”
She smiled, surrendered.
In the bathroom, he sat her down on the shower bench. He turned on the warm water, adjusted the temperature and got in with her. He took the soap, lathered his hands and began to gently wash each part of her body.
First her shoulders. Then her neck. Her arms. Her chest. Her belly. Her thighs. And between her legs — with the utmost respect, but without stopping to smile at the memory of what they had just done there hours before.
She just sighed. Her eyes closed. Trusting. Giving himself over to the care.
Then he washed his own body quickly, turned off the shower and grabbed the towel. He dried Nayara as if she were the most precious thing in the world. Every curve. Every fold.
“Do you have any idea how beautiful you are?”
“I do. Because you remind me of that all the time.”
He laughed, wrapped her in the towel and picked her up again.
In the bedroom, he slowly placed her on the bed, lay down on her side, and pulled the sheet over them both. Their legs intertwined naturally. Their breathing began to align.
In the darkness, with only the low light from the window, he caressed her back with his fingertips. And whispered:
“No matter how long I’m gone again… I’ll always come back to you. Always.”
She turned her face and pressed her lips against his chest.
"And I'll always be here. To be yours."
He kissed the top of her head.
And finally, they slept.
Exhausted and Satisfied.
