InuYasha Fan Fiction / Yu-Gi-Oh! Fan Fiction ❯ All Grown Up ❯ All Grown Up ( One-Shot )

This fic is the sequel to `Not a Kid Anymore'. I never intended to make a sequel, I rarely do so for a one shot, but, there were many people asking for one, so I figured, `Why not? You've got the time!'

 

 

This fic will help with a few unanswered questions that I unknowingly left hanging at the end of NAKA.

 

 

This is yaoi, this fic contains a lemon, this is Kohaku/Mokuba.

 

 

I don't own, okay! *Huffs* Break my heart why don't'cha!

 

 

 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

 

 

Kaiba Mokuba lounged about the Manor, sighing and staring at a wall, there was nothing to do, well, not until the guests arrived for his eighteenth birthday. He smiled slowly, six months had passed since he had met Kohaku, six months since he had met his soulmate. Six moths since Mokuba found out that Jou and his Nii-sama had set the whole darned thing up and BET on it! The audacity. He chuckled as he recalled Jou running around the house squealing and ducking objects as a shirtless Kohaku threw things at the blonde. Not to mention the anger on Kohaku's face as he learned his sister, Sango, was in on it too! The young girl had applied for a job a KaibaCorp, nothing more than a mere receptionist position, but, she was hired as Seto's personal assistant, and man, those two loved to talk.

 

 

 

His eyes moved upwards as he heard the doorbell, and he pushed himself out of the endless, comforting and squishy depths of the plush leather couch. “I GOT IT!” Running for the door Mokuba threw it open, his smile falling as he spotted Shizuka,

“oh, it's you, Jou's in the kitchen.” Stepping aside Mokuba turned, swinging the door shut and nearly having a heart attack at the thump and crash, he spun around, facing the still ajar door, a foot crammed between the door and it's frame. He opened it and his eyes went wide, “gomen! Gomen ne! Kohaku-chan!”

 

 

Kohaku waved his hand, brushing off his pants, “It's okay, not the first time.”

 

 

Mokuba hauled the other male inside, rolling his eyes at the doorbell, “Seto! Get the door! I have to make sure I didn't injure Kohaku!”

 

 

Kohaku chuckled, dusting off the last of his pants and pulled off his shoulder bag, fishing out a fair size wrapped package, “This is for you.”

 

 

Mokuba melted, plucking the gift out of Kohaku's hand, he smiled, “What is it?!”

 

 

Kohaku rolled his eyes, “Moku….”

 

 

Mokuba pouted, shaking the box lightly, “Is it chocolate? I like chocolate.”

 

 

Kohaku smiled, watching as Seto took the gift from Mokuba's hands and placed it on a table, “You'll just have to wait and see.”

 

 

 

“Demo, Nii-samaaaaaaaaa!”

 

 

Seto chuckled, “Just wait, not much longer, you'll have to open it with the others.”

 

 

 

~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~

 

 

 

Mokuba stared longingly at the gift table, fingers twitching as he longed to unwrap his gifts. Everyone had finally arrived and he was drumming his fingers against his knee impatiently, a bored look on his face. Kohaku walked over to the other dark haired male with a smile and sat next to him, holding out a cookie in offering. Mokuba smiled lovingly before biting into the cookie and chewing it slowly.

 

 

“Arigatou,” he mumbled around the food.

 

 

“No problem,” Kohaku returned, taking a bite of his own cookie, “so, what do you want to do?”

 

“Open my presents!”

 

 

Kohaku chuckled, ruffling up Mokuba's hair and getting a pout in return, Kohaku grinned and kissed below Mokuba's ear, “such a sexy mess.”

 

 

Seto walked over to the couch and smiled down at his younger brother, “you can open your gifts now, calmly, like a civilized person.”

 

 

Mokuba nodded and got up, practically dragging Kohaku along with him, before he sat down and scanned over the presents, grabbing Kohaku's with a smile. He tore open the paper, tossing it everywhere before stopping at a box, he tugged on it, before realizing it was sealed shut with tape. Turning the box, he yanked on the tape with a frown, muttering as it didn't snap. With a few more tugs the tape broke and he opened the box carefully, peering inside.

 

 

“Kohaku…” Mokuba breathed out slowly, “thank you…” Mokuba pulled out the silver locket, running his fingers over the designs on the metal. He unclasped the small heart and looked at the picture, smiling softly, it was from his and Kohaku's first real date. They had gone out for they day, and wound up at one of the photo booths, the picture was of he and Kohaku kissing softly. He snapped the locket shut and looked up at Kohaku, who took the necklace and fastened it about Mokuba's neck, before kissing his cheek before sitting in Mokuba's lap and pulling over the next gift.

Jou sat on the couch beside Seto, eating a slice of cake while watching Kohaku and Mokuba as they talked and ate cake. His golden eyes slid to Seto who was watching them with extra attention and he smirked at the brunette, snuggling close.

 

 

“You look like you're ready to kill the boy, Ryu-chan.”

 

 

“Hn. I think Kohaku is trying to steal what little innocence my brother has left.”

 

 

Jou chuckled, his eyes shutting slightly as fingers worked through his hair, “what makes you think he has any left? We were in a fully intimate relationship at their age.”

 

 

“Just because I do something doesn't mean he's to mimic my actions.”

 

 

Sitting up slightly, the blonde looked into blue eyes and pouted a moment, “are you saying that you regret sleeping with me so early on?”

 

 

Seto raised his eyes to Katsuya's before rolling them, and kissing the other softly, “of course not, I'm just saying I don't want Mokuba to get hurt.”

 

 

“Mmmm…Hurt is a bad thing, it's painful…” Jou murmured, before laying his head in Seto's lap and smiling as his `master' resumed his petting.

 

 

~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~*~

 

 

Mokuba collapsed onto his bed with a sigh, smiling happily as he stared at the ceiling, before sitting up as he heard his bedroom door open and then close. Kohaku waved and walked over to the bed, sitting on the edge of it and looking at Mokuba intensely. Mokuba crawled over and hugged Kohaku with a happy smile, before removing the tie from the brown-haired male's hair and watching the tresses fall free. Kohaku smiled and kissed Mokuba's neck, before looking to the Kaiba as he sat back.

 

 

Mokuba tilted his head, looking a Kohaku with a furrowed brow, “what's wrong Kohaku-chan, you look worried.”

 

 

“Nothing's wrong Moku,” Kohaku smiled, placing a hand on the other's cheek, “just admiring you is all.”

 

 

“Oh, that's good.” Mokuba replied before yawning slightly, covering his mouth with his hand.

 

 

Kohaku chuckled, kissing Mokuba's forehead, “tired?”

 

 

“Little bit.”

 

 

“How tired?” Kohaku asked, looking at Mokuba with a smirk.

 

 

Mokuba caught the smirk and gave his own, “not that tired…”

 

 

Kohaku grinned and leaned forward, capturing Mokuba's lips in a soft, passionate kiss, their lips parting to questing tongues as they fell back onto the bed. Mokuba's fingers ghosted over Kohaku's chest before they parted, rolling onto their sides to look at each other while still have their fun. Mokuba propped his head up with one arm, the other moved along Kohaku's chest with a lazy smile. Kohaku mirrored Mokuba's actions before taking hold of Mokuba's wandering hand and pressing a kiss to the knuckles before turning his intense gaze on his love once again.

 

 

Mokuba smiled, leaning forward to take Kohaku's lips, their kisses short but sultry as their tongues swept over lips and they moved together and parted with a soft smacking sound and low moans. Mokuba threw one leg over Kohaku's hips and moved them closer together, grinding their hips together with a groan. Kohaku pulled away from the kisses to remove Mokuba's shirt and toss it to the floor, before trailing his lips over the creamy neck and shoulder with practiced ease. Mokuba tossed his head back with a gasp, his hips moving on Kohaku's as he freed the other of his shirt as well and deposited it on the floor.

 

 

Kohaku grinned against Mokuba's flesh, knowing how impatient the boy could be he took hold of Mokuba's hips and rolled himself onto his back so Mokuba straddled him. The Kaiba gave a cry of bliss, hands on Kohaku's shoulders as ground his growing erection against the other's earning a fumbling moan. Mokuba's hands moved to the waistband of Kohaku's pants as he leaned down, hair brushing over Kohaku's skin as he pressed kisses to his stomach working his way upwards. Kohaku's hands moved to the waistband of Mokuba's pants as he began to work on the buttons of his jeans with one hand, the other he used to cup the bulge in the jeans while he bucked up. Mokuba gave a gurgling moan as his head fell back and his hands gripped the shoulders tighter as his eyes fell half-lidded. Leaning back down, he panted into Kohaku's ear, before licking it teasingly and then biting on the lobe. Six months of exploring one another's bodies had rewarded them of knowing exactly where weak spots were and how to use them to their advantage.

 

 

Kohaku gave a long moan as his tongue dragged up Mokuba's neck as the black haired boy shimmed out of his pants, wriggling his hips on Kohaku's with a naughty smirk. The two gazed into one another's eyes and Kohaku took hold of Mokuba's chin, before kissing his lips chastely, Mokuba smiled and returned the kiss, panting softly as he finally slid Kohaku's pants down and threw them onto the floor.

 

 

“Kohaku…” Mokuba gasped out, between breaths of air.

 

 

“Yes, Mokuba?” Kohaku asked, peering into the cobalt eyes with love.

 

 

“No more exploring, no more playing…I want you…”

 

 

Kohaku sat up slowly, arms around Mokuba's waist as he looked at the seriousness on Mokuba's face, he smiled nuzzling the other softly. “Then you'll have me…However you want me…”

 

 

Mokuba smiled, kissing Kohaku lovingly as he allowed the other to take control. Kohaku rolled them over, laying Mokuba onto the mattress slowly, before removing their lips and kissing Mokuba's neck softly. He slowly made his way down the Kaiba's body, worshipping his boyfriend in a manner only he knew. He licked and sucked; kissed and nibbled; leaving marks on the white flesh. He lowered his mouth over one dusky nipple and pursed his lips as he sucked softly, tongue lapping over the bud before swirling about it; he nibbled finally with just the right amount of pressure he knew Mokuba liked. The pale boy gave a hitched moan as Kohaku tortured him just right, eyes squeezed shut as he panted. Kohaku relinquished his hold on the nipple before looking up with a smirk, then continued his journey down. He traced his lips and tongue over the finely sculpted muscles of Mokuba's abdomen before dipping his tongue into his navel, earning a yelp. With a chuckle he further decended, hooking his fingers on the waistband of Mokuba's black silk boxers before pulling them down and tossing them away.

 

 

He kept his attention away from Mokuba's cock as he brushed his lips over creamy thighs before gently prompting Mokuba to roll over. Smiling at the exposed back, Kohaku swept Mokuba's hair to the side before kissing slowly down his love's back before resting at the small of his back and nibbled gently on his tailbone earning a wanton moan. Leaning back up Mokuba's body Kohaku kissed below Mokuba's ear and smiled, “you're perfect…”

 

 

Mokuba turned his head craning his neck for a kiss, which he received as Kohaku's lips settled over his own. The brown haired boy held Mokuba's head in place with one hand under his chin while the other slipped into the bedside table's drawer to locate the lubricant. As his fingers wrapped around the tube he smiled, glad both he and Mokuba had read up on the subject and, of course tried several experiments with each other before hand. Placing the tube by Mokuba's hip, Kohaku broke the tender kiss and caressed Mokuba's cheek before sliding down his body once again.

 

 

Trailing his fingers over the firm mounds of Mokuba's buttocks Kohaku smiled when the other boy shivered. Popping open the cap to the lubricant he squeezed some out onto his fingers before rubbing them together to warm the cold gel. With a soft kiss to Mokuba's hip, Kohaku lovingly slid the first finger into his boyfriend. Mokuba stiffened a moment, as he always did, gripping his pillow before relaxing with a sigh. Kohaku soothingly traced designs on Mokuba's hipbone as he worked the finger in and out with ease, stretching Mokuba with care. He took his time, wriggling the finger to hear Mokuba gasp and moan. Soon Mokuba was moving with his hand and he smiled softly, “okay?” He asked, getting a nod in return, “more?” He received another nod and with that he slipped in a second finger and waited for Mokuba to calm down.

 

 

When the body went limp, Kohaku began scissoring his fingers, biting his lip in determination as he hook his fingers and pressed deeper inward. Mokuba jolted and his legs trembled as he gave a mewl, with a smirk Kohaku repeated the action, getting the same result with a louder cry. He loved the way Mokuba reacted to his prostate being hit, the way he tightened around his fingers. Kohaku's eyes lidded when he imagined the feeling around his cock and he felt himself harden further. His free hand moved from Mokuba's hip to the right cheek of his buttocks as he caressed softly. Mokuba let out a groan, hands clutching onto the pillow tighter as he buried his face in the fabric, wiggling his hips as he tried to feel more. A third finger slipped in and Mokuba's mouth fell open with a moan as he bucked backward, trying to get the fingers in deeper. This was always the easiest part, no pain, only pleasure as Kohaku brushed over his prostate and he choked on a moan.

 

 

Kohaku groaned, he needed to feel Mokuba, and he needed to do it soon; sliding himself out of his boxers he tossed them to the floor. Mokuba gasped and whimpered as the fingers retreated before getting hushed with a kiss. Kohaku smeared the lubricant over himself and shuddered, before he took hold of Mokuba's hip with one hand. Breaking away from the kiss he looked into Mokuba's eyes and smiled lovingly, “ready?”

 

 

Mokuba nodded and smiled, “make love to me, Kohaku.”

 

 

At the allowing words Kohaku carefully began to push himself in, gasping at the tightness surrounding him. Mokuba stiffened and whimpered softly, hands fisting into the sheets as pain shot up his spine. Kohaku rested fully seated inside Mokuba, gritting his teeth as he waited for the slightly smaller boy to adjust. Mokuba's hands twitched in the sheets as he panted softly, willing his body to relax for his lover, slowly the pain began to subside and he focused on the fact that Kohaku was inside of him; making love to him. With a quiet moan, Mokuba's head bowed forward, hair brushing the mattress, forehead resting on the pillow as he pushed back against Kohaku slightly.

 

 

Feeling Mokuba move against him made Kohaku shiver and moan softly, as he drew his hips back slowly before pushing back into the welcoming heat. His forehead rested against Mokuba's sweat dampened back as he once again drew his hips out and pushed in. Mokuba's arms trembled before he slid forward slightly and rested his forehead against his folded arms. Kohaku gripped onto Mokuba's hip as he shifted slightly and pushed inwards with a bit more force. Mokuba stiffened slightly, thighs trembling as he gave a moan and tightened about Kohaku. Kohaku's eyes rolled back as he moaned, long and low, knowing he had found it. Pulling away before slamming into the spot again he gasped; Mokuba's back arched and he whined in pleasure, eyes shutting as he pushed back against Kohaku with a quiet moan.

 

 

“Why are you holding back, love? Let me hear how good you feel…”

 

 

“Don't,” moan, “want,” pant, “others,” whimper, “to,” gasp, “hear,” grunt.

 

 

“Who? No one here but you and me…” Kohaku emphasized his point by slamming his cock into Mokuba's prostate with force causing Mokuba's head to snap back as he let loose a scream. They both gave in then; not caring how loud they were being, nor who heard. Kohaku slipped one hand under them to grasp Mokuba's dripping cock and began to stroke in time with his heated thrusts. Mokuba shoved back against Kohaku without abandon, trembling as his prostate was struck continously. Kohaku pulled Mokuba against him, his free arm wrapping against Mokuba's waist as the other was seated over him. He thrust into Mokuba with a vengence, his thumb brushing over the freely leaking head as he stroked. Mokuba's head fell back onto Kohaku's shoulder as he bounced on the other's lap; eyes shut as he whimpered and moaned in rapture. Licking up Mokuba's neck Kohaku panted into Mokuba's ear, lips resting on the shell as he gasped and moaned, “come my love…let yourself go…show me how hot you look when you lose it…” Kohaku's voice was low, thick with passion and burning with lust.

 

 

Mokuba snapped, his hands tightening on Kohaku's hips as his eyes instantly slid open and rolled back into his head. His abdomen tightened under Kohaku's arms and a blush stained his cheeks. A harsh wail tore past his lips as his channel tightened against Kohaku, and his seed gushed from him and coated his chest and thighs as well as Kohaku's hand. He spasmed in Kohaku's arms, trembling as he clung to the other; attempting to ride out his orgasm. Kohaku's breath caught in his throat, entranced by Mokuba's release as he tumbled off the orgasmic cliff. He flooded Mokuba's channel to overflow with his semen, thrusting weakly as he rode out the orgasm with wide, hazed eyes.

 

 

Slowly coming back to himself, Kohaku lay Mokuba on the bed as he removed his softened cock, earning a whimper of protest. He cleaned his hand of Mokuba's come before lowering his head to clean Mokuba's chest and then moved further down to clean the milky thighs of their mixed semen. A hand knotted within his hair and he slid upwards, kissing Mokuba's sweat dampened lips softly, before pulling away with a smile. Mokuba's cobalt eyes slid open and he gave a tired smile, “mmmm…hi…”

 

 

“Hi yourself, you okay, love?”

 

 

“Better than okay, warm and tingly and sleepy.”

 

 

Kohaku smiled, kissing Mokuba's shoulder before entangling their legs and pulled up a blanket to cover them. He hugged Mokuba close and stroked the matted, raven locks. Buring his face in Mokuba's hair to breathe in their mixed scent he turned his face downwards as a hand was pressed to his cheek. He turned his face into the palm and pressed a soft kiss to the skin before taking Mokuba's lips in a slow, loving kiss which was returned whole heartedly. Pulling away Kohaku settled his head on Mokuba's chest, listening to the strong heart beat and allowed his eyes to shut with a yawn.

 

 

“Love you Moku-chan.”

 

 

“Love you more, Kohaku-chan.”

 

 

“Love you always…Happy birthday.”

 

 

“Arigatou, my everything.”
