The soft blue light of the moon was just giving way to the pale white day moon as Cosmo opened his eyes sighing heavily realizing he'd slept in his glasses again, thankfully he mostly slept on his back rather than tossing and turning, before getting out of bed and going to his closet selecting his clothes for the day. Once he had dressed he quietly slipped out of his room and down the hall to the door of Nation's room peeking in the open door, he looked around the room until he knew his sister wasn't awake before he quietly stepped into the room and to the side of her bed. He reached out to shake her shoulder but froze as she rolled over onto her back in her sleep and suddenly his heart seemed to skip too many beats before racing overtime to make up for the skipped beats, his throat became dry, his palms felt sweaty, and there was an odd feeling behind his navel that was quickly spreading lower as his eyes looked over her sleeping face.
At 13 Nation had blossomed into a rather beautiful young woman, her skin was flawless and soft creamy white, her slightly parted lips were still the same dark pink as when she was born but were now a little fuller, her long red hair was fanned out beside her head on the pillow in a halo of fiery curls that contrasted with her white pillow case, her body though not fully developed was coming into a lovely hourglass shape making her clothes fit a little more snug if they were small enough, and right at that moment all Cosmo wanted to do was kiss her soft lips and run his fingers through her hair holding her close to him.
Shaking his head Cosmo reminded himself it was his sister he was thinking about but his heart still insisted on beating too quickly and the odd feeling was still present but duller than before. After taking a few deep breaths to slow his heart he reached out and lightly shook her shoulder.
"Come on Nation, time to get up we have school."
Nation groaned in her sleep rolling back over pulling the blanket over her head.
"Five more minutes."
Cosmo couldn't help but chuckle at her reply, even if it wasn't unusual seeing as she was never a morning person, and snuck his hand under the blanket to her hip where he started tickling. That woke her up at once and made her start laughing trying to get away, smirking he held her around the waist so she couldn't get away but as he held her against himself the strange feeling returned making him stop his tickling at once causing her to look back at him confused.
"Cosmo? Are you okay?"
At first Cosmo didn't hear her but once he did he shook his head clear and offered an apologetic smile.
"Sorry I was up late studying for exams so I'm a little out of it."
Nation looked unconvinced but said nothing as she got out of bed and went to her closet, watching as she walked across the room Cosmo's eyes trailed over her body barely covered by her silk night dress that stopped just below her backside, he get his throat get dry again as his heart sped back up and the feeling returned with a vengeance making him blush horribly as he realized exactly what it was. As quick as a blink he was off the bed and at the door making Nation raise an eyebrow at him.
"I'm going downstairs to make breakfast."
He cursed himself in his head as his words came out a little strangled but not wanting to find out if his sister noticed he left the doorway and went down to the kitchen where he paced the floor shaking his head. Why was he getting aroused by his sister?! Yes of course she was beautiful, gorgeous even despite being 13, but she was his flesh and blood sister and she was only 13 not even a legal adult on Transexual yet and she wouldn't be until she was 16. After glancing around to make sure no one else was around he quickly splashed cold water on his face then began thinking over the complicated math questions he'd studied last night taking his mind off his sister as he started breakfast.
As he was putting the plate of toast and eggs on the counter Nation came into the kitchen wearing a black skirt that stopped just short of her lower thigh, a white blouse that had the top most button undone, her hair had been tied up in a bun, and her makeup done expertly. Upon seeing her Cosmo quickly dropped his eyes to the task of not burning his own breakfast as Nation sat at the counter and began to eat watching her brother closely not missing how every now and then when he'd steal a glance at her he'd shift his weight from one foot to the other. She was about to ask him what was wrong when their mother came into the room.
"Good morning you two."
Nation smiled returning her mother's kiss on the cheek before looking at the clock and nearly choking on her orange juice.
"Crap! Come on Cossy or we'll be late!"
Cosmo blinked then looked at the clock swearing under his breath as he quickly transferred the nearly over cooked eggs onto a plate before grabbing a piece of toast and kissing his mother on the cheek then following Nation out the door. The walk to school was silent making Nation worry she'd done something to make her brother act this way.
"Hey Cossy?"
Cosmo looked at his sister out of the corner of his eye but found she was looking at the side walk.
"Yes Nation?"
Nation seemed to hesitate before biting her lip.
"D-did I do something to make you mad at me?"
Cosmo blinked surprised at her his heart sinking into his stomach feeling horrible for making her think she'd done something wrong.
"Of course not Nation, you haven't done anything I promise! I told you I was up really late so I'm just not here today, it's okay you didn't do anything wrong."
Nation looked up at him her eyes wet with tears making the knife in his heart twist, he stopped walking and grabbed her wrist pulling her into a close hug. She hesitated a second before wrapping her arms around his waist hiding her face in his shoulder.
"Tell you what, to make up for being a jerk this morning how about after school we do something, anything you want."
Nation smiled looking up at him.
"Anything?"
Cosmo chuckled doing his best to if or the tightness in his chest.
"Anything."
Nation thought carefully before her smile returned.
"Ice cream and walking the long way home?"
Cosmo couldn't help but smile, his sister may have been 13 but when she wanted she could be very much a child, taking the long way home meant rather than walking through the city they followed the beach around it adding nearly an hour to their walk. He pretended to ponder the thought taking her hand as they started walking.
"Hmmm well I don't know, that walk is so long and I'm bound to have a lot of school work."
Nation pouted looking up at him.
"Come on Cossy, you said anything."
He chuckled as she gave him her famous pouty look that won nearly anyone over but he composed himself sighing as he put his free hand in his pocket shaking his head.
"No I don't think we can do that this time Natty."
Nation looked at him like he was crazy then caught the smile in his eyes that slowly spread over his lips upon seeing her face. Laughing she playfully punched his arm making him finally crack and laugh with her as they reached the junior academy.
"You're a prick you know that?"
Cosmo rolled his eyes but kissed her cheek.
"Love you too little sister, I'll wait here for you after my last class."
Nation smiled brightly returning the kiss.
"Alright see you later, stay out of trouble!"
With that she waved then hurried up to the front of the building where a group of girls were waiting, after watching them go inside Cosmo walked down the street to the academy. After his first few classes he was sitting at his desk in Transylvanian Anatomy flipping through his text book waiting for his peers to finish the assignment he considered child's play. A hand gently tapped the top of his book making him look up to find his teacher Mrs. Laceworth, the academy principal, standing in front of his desk her face expressionless.
"Can I see you in my office please Mr. McKinley?"
Cosmo nodded swallowing thickly as he got up from his seat to follow.
"Better bring your things, this may take awhile."
Cosmo nodded and grabbed his bag trying to ignore the whispers that spread through the class until the whole room was murmuring words like 'expulsion' and 'grade skipping'. Laceworth led Cosmo from the classroom and to her office where she gestured for him to sit down in the chair across from her own with the desk between them, he sat down trying to hide his nervousness as he watched her sit in her own chair. Laceworth wasn't intimidating in appearance, in fact she was almost the opposite, she was rather beautiful with raven hair that fell over her shoulders and down her back in a light wave, her eyes were a bright icy blue, her lips were always painted deep ruby red, and she was rather short only coming up to most people's shoulders but none of that stopped her from being one of the most feared people in the building.
Seeing Cosmo shifting nervously Laceworth smiled gently crossing her legs.
"You can relax Cosmo, you're not in here because you're in trouble quite the opposite really."
Letting himself relax a little Cosmo gave a small smile.
"The opposite ma'am?"
She nodded opening a drawer of her desk taking out a pamphlet and set it on the desk top sliding it to him.
"Yes Cosmo, it would seem your academic achievements have caught the eye of not only the local college but the private university as well."
Cosmo looked at the little booklet before him showing the top private university on Transexual, Starcross University, and wanted to rub his eyes not believing it.
"I don't understand...when?"
Laceworth chuckled at his reaction leaning back in her chair crossing her arms over her ample chest.
"During the career exhibition last month, they were taken by your doctoring interest and your academic status. As I'm sure you know the school has a good medical course that would help you get your doctoring degree but there are other courses to take if you change your mind, the headmaster said he would be sending an invitation for you and your family to tour the school if you wished."
Cosmo smiled for a moment before it faded and he looked at his hands in his lap making Laceworth raise her eyebrow.
"As amazing as it is to hear I'm not sure I'd like to attend Starcross ma'am, I was actually hoping to apply early for a different university later this year."
She looked him in the eye willing him to continue which he did after a moment of chewing his lip.
"I was hoping to apply for The University of Transylvania later this year."
Laceworth's eyes widened a bit shocked that at 15 he was already setting sights on the highest ranking college in the galaxy, but smiled softly opening her desk again and taking out a new pamphlet and a few papers handing them to him.
"I'm impressed by you McKinley, you're 15 years old and have a better plan for your future than most of the 18 year olds here. These are this terms application forms for The University of Transylvania, they are due back no later than the day after tomorrow if you pass the application then you will be placed on a list until you are 17 to take the entrance exams then if you pass those you will be allowed to attend."
Shell shocked for a moment Cosmo could do nothing but look at the forms beiges he broke out in a wide smile taking the forms.
"Thank you so much Mrs. Laceworth! I'll be sure to return these as soon as they are filled out!"
Laceworth chuckled and gave a dismissive wave as she smiled.
"Go back to class before I give you detention."
Still smiling Cosmo grabbed his bag and hurried back to class obvious to the whispers as he sat at his desk flipping through the pamphlet. Down the road at the junior academy Nation was sitting at lunch with her friends listening to Nellie talk about her newest boyfriend, James or Jude or something of the sort she wasn't really listening as she pushed her food around her plate. Beside her a girl with brown hair and green eyes nudged her arm making her look at her.
"You okay Nat? You seem out of it."
Nation shrugged as she looked back at her plate stabbing a blueberry with her fork.
"Just thinking is all."
The girl didn't look convinced but left it alone going back to her own lunch, after a few moments of listening to Nellie talk Nation looked back at the girl beside her.
"Hey Nida you have a boyfriend right?"
The girl, Nida, turned her green eyes to Nation and nodded as Nellie shut her mouth for once to listen.
"Yeah Derek, why?"
Nation but her lip blushing a little.
"Are there ever moments where you'll just goofing around where he's tickling you or just holding you and then he gets flustered and blushy?"
At this all the other girls shared looks then smiled.
"Then he stammers a lot, his voice sounds kinda strangled, his palms are clammy, and tries to stay at arm's length?"
Nation looked at Nellie raising her eyebrow wondering how she knew exactly what she was talking about but she nodded none the less.
"Yeah that too."
Nida giggled and nodded her cheeks flushing a little.
"It happens a lot but we've learned to go with it because of what it means."
Nation looked confused making the girls laugh until she growled her cheeks turning red.
"Calm down Nat it's a good thing, you're a first timer so of course you don't know what it means."
Nation turned her forest green eyes on Nellie narrowing them.
"Oh yeah if you're so smart what does it mean?"
Nellie smirked biting her carrot stuck in two.
"It means he's getting excited."
Nation raised an eyebrow thinking that just didn't make sense.
"Excited?"
Nellie rolled her eyes pointing the carrot stick at her.
"You're too innocent for your own good Nat. Excited, happy, eager, aroused!"
Hearing the last word all the color drained from Nation's face before coming back in such a rush her whole face turned pink causing a giggle to spread around the table.
"I didn't think you had a boyfriend Nat, that brother of yours always hanging over you it amazes me you got one."
Nation blinked a couple times looking at Nida then shook her head slowly.
"He's not...he's just a childhood friend, does it always mean they feel that way about you?"
The other girls shared a look and Nellie shrugged.
"I guess not always, at like 15 they get that way at anything remotely attractive they can't help it adolescence is a cruel mistress."
Nodding absentmindedly Nation was thankful when the bell rang so she quickly bolted up and hurried to her class before her friends could start asking who this 'friend' was. After her last class she hurried out of the school, being careful to avoid her friends, and found Cosmo waiting for her, she smiled taking his arm as he offered it to her as they began walking to the ice cream shop. They talked about random things as they walked barefoot through the sand eating the last of their ice creams when Cosmo looked over at her biting his lip.
"I got called into the office today."
Nation looked up at him raising an eyebrow, it wasn't everyday those words came out of her brother's mouth.
"What'd you do?"
Cosmo chuckled shaking his head.
"I didn't do anything wrong, actually the principal called me into her office to tell me that the college was interested in me."
Nation nearly choked on her bite of waffle cone looking up at him.
"That's amazing! Which collage?"
Cosmo gave a half hearted smile.
"Starcross."
Nation blinked surprised knowing that was one of the top schools on the planet that rarely scouted anyone under 16.
"Wow Starcross, that's big, mother went there didn't she?"
Cosmo nodded looking down at the sand under their feet.
"Yeah she did, a minor in Transylvanian medicine and a major in Basic Teachings."
Nation nodded.
"She'll be happy to hear they are scouting you."
Cosmo didn't respond making her look at him.
"What's wrong? I thought you'd be happy."
He shrugged taking her hand in his.
"I'm impressed that's for sure but I don't want to go to Starcross, I want to go to The University of Transylvania, I told Mrs. Laceworth that and well she gave me an application form. If I fill it out and turn it in and they think my academics are good enough I'll be put on a waiting list so when I turn 17 when I can take the entrance exams then if I pass those I can attend."
Something flashed in his sister's eyes for a second before it was gone and replaced with a happy smile.
"That'll be amazing if you get in Cossy they'd have to be idiots not to take you."
He chuckled squeezing her hand then looking up at the sky seeing the clouds were beginning to darken.
"It looks like it's going to storm soon, we should hurry."
Nation looked up at the sky and nodded before walking faster as they neared home, no sooner had they walked in the door did it start to pouring. Later at dinner Cosmo brought up the subject of being scouted and just like Nation said their mother donned a proud smile congratulating him doing the same after he said he was going to try for the other school. After dinner and later in the night Cosmo had just turned off his desk lamp after filling out the acceptance form and gotten into bed about take his glasses off when his door opened a crack making him sit up to see who it was.
To his surprise Nation was standing in the doorway wearing an old t-shirt and a pair of shorts biting her lip.
"Cossy are you awake?"
Sighing with a small smile he moved over and opened the blankets for her.
"Come on."
Nation smiled and stepped into the room softly closing the door before crawling into bed beside him relaxing as he laid down and pulled the blanket over them, it wasn't odd for Nation to slip into his room during a storm ever since she was little she'd been doing it seeing as she couldn't sleep. Once they were both settled Cosmo wrapped his arm around her waist holding her close as she began to drift to sleep, looking down at her Cosmo blushed as his eyes fell on her lips, slightly parted and soft looking, and before he could really think he leaned down gently kissing them.
As soon as Nation felt her brother's lips on hers she froze now wide awake with wide eyes looking at him. After the initial shock wore off she relaxed a little and was about to kiss back but he pulled away looking mortified.
"N-Nation I'm so sorry!"
Nation felt her heart break out of her chest as she ran her fingertips over her lips tears slowly gathering in her eyes get a small smile on her lips. Cosmo didn't see the smile all he saw was the tears and pulled her close to him relaxing a little when she wrapped her arms around his neck and hid her face in his shoulder, her body shuddered with her sniffles and tears were pelting his shoulder now and again for a few minutes before she managed to stop crying and looked up at him tears still in her eyes.
"Nation I'm sorry, I don't know what came over me I just-"
He was cut off by her lips being pressed to his leaving him shocked at first but slowly he kissed back cupping her face in his hands rubbing away her tears with his thumbs. When they broke apart out of breath Nation raised a hand to his cheek gently stroking it with her thumb.
"Don't be sorry, you didn't do anything wrong."
Cosmo leaned into her hand closing his eyes.
"But I kissed you, I'm your older brother I shouldn't have done that."
Nation rolled her eyes moving so she was sitting in his lap gently placing their foreheads together.
"I don't care if you're my brother or not, I'm just happy my love isn't one sided I thought you knew I've worn my love for you on my sleeve since I was 6 and you saved me from Gideon."
Cosmo chuckled stealing a kiss from her making her giggle.
"Well how was I supposed to know that you were serious?"
She shrugged kissing him again giggling into it when he wrapped his arms around her holding her closer, she could feel his heart hammer away in his chest in time with hers. Hesitating a moment she gently ran the tip of her tongue along his lower lip silently asking for entrance which to her surprise he gave her parting his lips letting her slip her tongue into his mouth. After a moment of this kiss they broke apart panting, Nation's cheeks were red bringing out the very faint freckles that hid on her nose, letting her get her breath back he gently kissed each freckle before trailing his lips down her jaw pausing at the corner of her mouth.
Feeling his lips like a hot iron on her skin Nation let out a sound between a moan and a purr arching her chest into his, biting her lip she gripped the hem of the t-shirt he wore tugging it up and to her surprise he moved away enough she could pull it off him before capturing her lips in a fiery kiss again. Feeling heat pool behind her navel and between her legs Nation gave a small whine into the kiss guiding his hands to the bottom of her own t-shirt without breaking the kiss, without needing further instruction he lifted it over her head tossing it aside with his before guiding her to lay down against the pillows trailing his lips down her neck making her give little sounds and gasps.
As he reached the top of her bra he stopped reality crashing down on him as he looked up at her, she was laying against the pillows, eyes closed, lips parted as she panted a little bit, her cheeks red and her body squirmed now and again with a feeling she didn't yet understand as her pink painted nails dug into his shoulders. Closing his eyes he pulled away from her sitting on the edge of the bed taking deep breaths holding his head in his hands, Nation felt him pull away and opened her eyes her brows knitting together as she found him sitting at the foot of the bed so getting up on her knees she moved to kneel behind him placing her hands on his shoulders.
"Cosmo what's the matter? Don't you want this?"
Feeling her touch like fire Cosmo looked over his shoulder at her placing his hand over her's.
"Of course I do Nation, I love you but as much as I want this I can't. You're only 13 you're not ready for this, if we do this it's going to hurt you a lot because physically you're not ready and I can't do that to you."
Nation listened to him looking into his eyes, she could tell he was being sincere and not just trying to tell her nicely he didn't want her, her heart sinking a little but she smiled kissing his shoulder.
"It's okay, let's just lay down then I want to be close to you."
After taking a deep breath and hesitating a moment Cosmo let her pull him down beside her on the bed and cover them with the blanket. As she snuggled close to him he wrapped his arms around her burying his face in her hair closing his eyes letting himself relax feeling her breathing even out before falling asleep himself. In the morning Patricia carefully opened the door to Cosmo's room to tell him he'd gotten a letter but smiled when she found him sound asleep holding Nation close to him as she slept nestled against his chest, shaking her head Patricia quietly left the room closing the door again with a soft click deciding to save both children the embarrassment of being found half naked by their mother.
Later that week, after sending in his application form, Cosmo came home from school smiling from ear to ear.
"What's gotten into you?"
Cosmo looked at his mother and handed her the letter Mrs. Laceworth had given him that morning letting her read it over before she smiled and kissed his cheek upon reading he'd been accepted to take the entrance exams in just two years.
"Oh Cosmo this is amazing! I'm so proud of you!"
Cosmo chuckled rolling his eyes as she hugged him before letting go and looking at the doorway hearing footsteps.
"What's going on?"
Cosmo followed his mother's gaze to find Nation standing in the kitchen doorway looking sleepy, her red curls hung over her left shoulder messily, her cheeks were lightly flushed, she was still in her pajamas which consisted of one of his shirts and a pair of shorts, her dressing down hung loosely on her shoulders and her feet bare. Feeling a little rush of guilt about forgetting his sister had to stay home sick from school he set the letter on the counter and went over to her wrapping his arms around her waist holding end close so she let out a content sigh and closed her eyes nuzzling his chest.
"So what's all the noise about?"
Cosmo chuckled gently running the back of his finger over her flushed cheek as she looked up at him.
"I passed the acceptance point for The University of Transylvania."
Nation smile closing her eyes leaning into his touch.
"That's great Cossy, I'm happy for you."
He smiled gently before leaning down and softly kissing her rubbing her back.
"Thank you Natty, that means the world to me."
She chuckled into the kiss pulling away enough to look in his eyes.
"If you get sick don't blame me."
Cosmo rolled his eyes putting their foreheads together.
"I'm not going to get sick."
Nation gave a low growl, more playful than threatening, putting her hands on his chest.
"You will if you keep kissing me."
"I will not."
"Will too."
"Not."
"Oh shut up and kiss me already."
Cosmo chuckled as their little banter came to an end and he tilted her chin up kissing her leaving their mother to shake her head but smile as she continued making dinner.
x~3 years later~x
Three years had passed like 30 for Nation being separated from her brother who had been accepted into The University of Transylvania, in his absence she didn't date anyone or even let another guy take her to any of the school dances much to the confusion of her friends but she didn't care she was too busy counting off the days until school ended and Cosmo would come home for the break. On the day Cosmo was to arrive home Nation convinced her parents to let her stay home so she could go along to meet him at the spaceship terminal, as they waited at the terminal Nation was unable to sit still making her mother shake her head but smile knowingly while her father tuned it out.
Finally the ship from Asexual arrived and people came out many of them students from the colleges but scanning the flood of people Nation didn't see her brother anywhere among them. As the last few people were coming out of the ship she finally seen Comao step out and look around for them, without warning she ran at him nearly knocking them to the ground as she threw herself at him hugging his neck.
"Welcome home!"
Cosmo chuckled hugging her back around the waist before lifting her up enough to spin her around a few times making her laugh as he set her back down.
"I'm happy to be home, I missed you."
Nation smiled looking up at him standing on tiptoe and kissing him purring as he tangled a hand in her hair deepening the kiss only breaking away when they needed air making her chuckle breathlessly.
"I missed you too, so very much."
She nuzzled his shoulder making him smile holding her close as he looked up seeing their parents come over. Patricia figured Nation wasn't going to let go of her brother any time soon so she settled for kissing Cosmo's cheek.
"It's great to have you home again, maybe now Nation will stop needing to ignore any invitation to go somewhere with her friends."
Nation blushed looking at their mother.
"Mooooom you weren't supposed to tell him that!"
Patricia chuckled holding up her hands before giggling a little as Richard wrapped his arms around her waist pulling her close. After returning home Nation helped Cosmo settle his things back in his room then sat on his bed watching him as he put his clothes in his closet hoping he wouldn't notice a few of his shirts missing, unfortunately he did looking back at her realizing for the first time she was wearing one of his shirts making him sigh but smile.
"Really Natty, my shirts?"
Nation smiled innocently.
"What do you mean? I haven't taken any of your shirts, maybe mom's washing them."
Cosmo raised an eyebrow at her going over to sit beside her on the bed taking the collar of the shirt in his fingers.
"Oh really then where did this come from then?"
She smirked shrugging.
"I found it."
Shaking his head he pulled her into his lap placing his hands on her hips.
"Where did you find it?"
Nation smiled slyly leaning in close so there was barely a breath between their lips.
"Your closest."
She teasingly flicked his lower lip with her tongue then moaned softly as he kissed her gently tugging her lower lip with his teeth. Letting her lips go he looked into her eyes as she smiled.
"You've become a tease you know that."
Cosmo smirked kissing her again for a moment.
"How do you know I haven't always been?"
Nation laughed putting their foreheads together.
"Very true. God I've missed bantering with you."
He smiled taking in her laugh holding her close.
"I've missed it too it not as much as I missed just being with you."
They lapsed into easy silence just enjoying being around each other until a soft knock sounded on the door making Cosmo break eye contact with his sister to look at the door.
"Come in."
The door opened and Patricia looked in smiling sheepishly.
"Sorry it interrupt you two but dinner's ready."
Cosmo nodded watching as she left closing the door behind her. Nation sighed kissing him one last quick time before getting up walking to the door being sure to put a little more swing in her hips. Cosmo watched his sister walk to the door and swallowed thickly feeling his arousal start to climb as he watched her hips sway, now that she was 16 Nation had filled out beautifully, her chest was ample, her hourglass figure was highlighted by new curves that had nothing to do with fat, and shed learned how to use her new adornments to her advantage already.
Smirking Nation opened the door then turned back to her brother.
"Come on then before she gets mad."
Cosmo shook his head snapping himself out of his thoughts and got to his feet following her down to the kitchen. At dinner he told about his classes and what he was learning as well as some of the parties other students would have, Nation listened carefully to try and figure out if he'd experimented or been with any other girls then gave a silent sigh of relief when it didn't sound like he had. After helping clean up after dinner Nation went to her room to get her pajamas and take a shower, as she was making her way to the bathroom she passed Cosmo's door and paused hearing panting mixed with something mumbled she couldn't quite understand.
Biting her lip she tiptoed closer to the door and listened closer, she could hear her brother panting and mumbling her name. Brow creasing she silently opened the door enough to peek in then gasped seeing her brother lying in his bed pleasuring himself saying her name between gasps. Quickly covering her mouth she hopped her brother hadn't heard her but unfortunately the sounds from his room stopped and after some rustling around the door opened to reveal Cosmo standing before her in just his pajama pants to find her standing there blushing redder than a tomato her hand clamped over her mouth.
Cosmo flushed just as red avoiding looking her in the eye as he swallowed thickly.
"N-Nation what are you doing out here?!"
Nation opened and closed her mouth a few times trying to speak as she dropped her hand to her side before finding her voice.
"I was going to the bathroom to take a shower and I heard you and thought you might be hurt."
Her cheeks burnt impossibly more, a sight he found endearing, as she looked at the floor shifting and biting her lip. Watching her he felt his heart melt a little as he gently tilted her chin up to look at him and kissed her lips smirking as she eagerly kissed back.
M"Did you like what you saw that much?"
Nation broke the kiss to smirk at him wrapping her arms around his neck.
"Maybe."
He chuckled kissing her again deeper this time making her go weak in his arms kissing back fiercely. They broke apart panting but Nation bit her lip looking up at him through her lashes, he knew that look she always gave it to someone when she wanted something.
"Cosmo?"
Already guessing where her question was heading he moved his lips down her jaw to her neck sucking lightly at her pulse point making her shudder and stamer a little over her words.
"C-can we finish what we started 3 years ago? Please I need you, I want you."
He smiled against her neck at her blunt words but reluctantly pulled away from her neck taking the chance to mess with her a little as he pretended to think on it.
"I don't know Natty."
She suddenly looked sad and heartbroken believing he was really going to turn her down as a tear slid down her cheek. Mentally cursing himself he moved to fix the misunderstanding by kissing the tear trail away then kissing her lips until she responded in kind wrapping her arms around his neck and pressing against him. Gently biting her lower lip he lifted her into his arms and carried her into his room closing the door with his foot before laying her on the bed finally breaking the kiss to look at her putting their foreheads together making her smile.
"You tricked me."
She gave a breathy laugh leaning up so her lips were at his ear.
"Maybe a little but this time I know you want me too."
Cosmo smiled kissing her deeply until it felt like their lungs would burst.
"I wanted you the first time but I wasn't ready neither were you."
Nation purred as he kissed her neck letting the subject fade away as her mind began filling with pleasurable haze. Moments later they were exposed to one another, their clothes strewn around the room, as they kissed deeply before breaking apart to meet each other's eyes their foreheads together.
"I love you Cosmo."
Cosmo lightly kissed his sister's lips.
"I love you too Nation."
With that she wrapped her arms around his neck and kissed him deeply muffling her cry of pain and pleasure as their bodies joined in the most intimate way for the first time. Half an hour later they lay under the blankets holding each other sweaty and spent but content, Cosmo sat against the pillows on his back while Nation lay on top of him her head on his chest as he lightly drew circles on her back as she slowly drifted in and out of sleep. When he thought she'd fallen asleep his hand paused on her back as he looked down at her but found her eyes open as she looked up at him and smiled softly bringing her hand up to gently stroke his cheek.
"Night night It's time for bye-byes, it's been a great day, thanks a heap now it's time for everyone to go to sleep."
Cosmo chuckled slightly as she sang the last bit of the lullaby their mother used to sing to them before he kissed her finger tips making her smile.
"I love you Cosmo."
He smiled gently rubbing her back.
"I love you too Nation, I always have and I always will."
She smiled tiredly and let her eyes close as he rubbed her back until she was asleep. Once she was asleep he let his own eyes close as he fell asleep holding her close.
