"Siggy, push harder! I want to go higher!"

It was a cool autumn day. Their papa had taken them to the park. He was sitting on bench talking on the phone, though also making sure the two of of them were in his sight. On occasion he pause in his conversation to call to them when they strayed too far out his view.

Right now they were at the swings. Papa hadn't yelled at them yet so Sigma assumed they hadn't gone too far. He did however call for him to be careful with his brother when he caught how hard he was pushing him on the swing.

"Don't let your brother fall! Remember he's smaller than you so you have to be gentle!" The man had said.

And so despite his brother's encouragement, Sigma had to resort to a more gentler pushing.

"Higher!" Atsushi insisted.

"Can't. Papa will get mad." The older boy replied.

His little brother made a pouting noise and dejectedly kicked his little legs back and forth. Clearly unsatisfied with this. "I'm bored. I wanna get on the slide then."

"You said you were bored of the slide and that's why you wanted to get on the swings."

"I wanna go back to the slide now. I wanna go down the swirly one."

Sigma could only sigh. Baby brothers could be so indecisive. Though Atsushi was lucky he was such a cute baby brother. Otherwise Sigma would've said no.

"Alrighty, Tigger. Come on. Hop off the swing and we can go to slides."

His baby brother made a noise of delight and with Sigma's help slipped from the swings. Hand-in-hand he tugged him over to the playground, hopping along—because Tiggers only hopped everywhere, that was the rule. Going boing boing boing the entire time was another important rule—the entire way.

"Siggy! Hop too!" The little boy insisted. "We can be Tiggers together!"

And Sigma laughed. "Okay! Okay! I'm doing it!" He said, attempting to hop in rhythm with his little brother. A rather difficult thing to do since four years tended to lack any sense of rhythm and Atsushi unfortunately was no exception.

But still it was more fun than walking at least.

The slide was part of bigger play structure with monkey bars, a jungle gym, and various other playground things children found fun attached to it. Sigma had to help Atsushi up the structure since the steps were so high up for his little legs.

"Siggy?" Atsushi asked as they hiked up.

"Yeah?"

"Can we go on the big kid slide?"

"Thought you wanted to go on the swirly one?"

Said big kid slide was a part of the same play structure. It was set higher up off the ground and thus a bit steeper—as well as lacking any of the fun swirls Atsushi liked about the other slide. It was dubbed "the big kid" slide because a lot of older kids used it. Though they mainly used to it in dares to jump off of it rather than actually sliding down it. Sigma himself had gotten an earful from their mother when she'd caught him in the middle of one of these dares…

"I wanna be brave like you." Atsushi tugged insistently at his hand.

"You sure?" He asked. "It might really be too big and scary for you."

And the little boy vigorously nodded his head.

Sigma supposed there was no discouraging him then. And as long as he stayed with him, he guessed it was okay.

Hand-in-hand still, Sigma guided Atsushi—after hiking up another set of steps to the bigger slide. They were at the highest point on it, allowing them a full view of the park. The two of them waved at their father below and he responded by waving back and raising his phone to take a picture.

"Okay ready?" Sigma asked as he looked down at his brother. He noticed that Atsushi actually looked a little hesitant. "If you're too scared we can go back to the smaller one."

Atsushi shook his head. "I wanna be like big brother. I wanna go down big kid slide."

"Want me to go down and wait for you then?"

Another head shake and Atsushi clung onto his arm. "Stay."

Sigma smirked. "You know big kids go down the slide by themselves."

Atsushi poked his lip out. "Stay." He insisted again, hugging his arm tighter.

He couldn't ignore a demand like that even if he wanted too. Especially when his baby brother made a pouty face like that. Asides he had to be a good and responsible big brother after all. And that meant going down the slide with him.

Also Atsushi would probably cry otherwise…

"Okay, come on." Sigma said as he guided his brother to sit down with him at the top of the slide. Atsushi sat in front and he had his arms securely wrapped around him. Papa would be upset if Atsushi got hurt going down after all.

Atsushi for his part giggled with excitement, kicking his little legs eagerly as they settled down.

"Siggy not gonna let go?" He asked.

"Relax. I got you." Sigma reassured as he held his little brother tighter.

And together they went down the slide.

12 Years Later…

Nikolai: so since u have the apartment to urself this weekend are u finally getting some action?

Sigma rolled his eyes at the text his roommate sent. The man was supposedly on some weekend vacation with his boyfriend, leaving Sigma with "free-reign"—Nikolai's words not his—of the apartment until he was back on Tuesday. Yet even miles away on a romantic trip Nikolai was finding ways to bother him.

I told you my brother was coming over this weekend.

I don't plan on getting any action while he's here.

He sent back.

It was a long weekend for the schools and students were getting Monday off. So their parents were allowing Atsushi to stay the weekend at Sigma's apartment. In fact, he could hear the boy shuffling through the door right now, calling back his goodbyes to their mother.

"Sigma! Hey where should I put my stuff?" He heard his brother ask from the living room.

"Just lay it by the couch. My roommate isn't going to be here this weekend so he's not going to complain about it." He called back from the bedroom.

"Okay!"

"And hey if you have any homework you can do it at the table. If Nikolai has any junk in your way, just move it." He called again. "And don't roll your eyes. Dad says I have to be responsible with you while you're staying the weekend."

There was a pause that was mostly occupied by an eye roll. He even thought he heard a disgruntled mumble.

"…Got it!" His brother eventually responded, his tone purposely dripping with exasperation.

Hs phone chimed again.

Nikolai: ah yes ur sweet wittle baby brother that u always go on about how cute he is

Nikolai: come on it gets super depressing seeing u sit around with a dry dick

Nikolai: u should have come with me and fedya

Nikolai: we had room 4 a third ;)

Sigma wrinkled his nose up at that. He had no idea why his roommate was always insistent on prying into his sex life. He's had plenty of hookups before. They just weren't his priority. Though apparently to Nikolai that just meant he was in denial and dying from lack of intimate companionship.

Sorry not interested in the weird shit you and Fyodor get up to

Have fun though

Unlike Nikolai, Sigma tried not to pry too much into his roommate's bedroom habits. But sometimes they were difficult to ignore. Especially when they involve walking in on said roommate assembling a person sized cage in the living room once…

Sigma had refused to listen to Nikolai's gleeful explanation that day. Simply turning around and walking out, telling him to text him when he and Fyodor were finished with whatever they'd been planning on doing.

Nikolai: have fun with ur weekend with the lil bro

Nikolai: unless thats some weird code for a booty call

Nikolai: either way enjoy urself

He thought about further arguing with Nikolai that he wasn't planning some secret "booty call" while he was away. However, he thought better of it. Protesting would only spur him on. And asides, he had other things to focus on instead of his roommate's weird antics.

Shoving his phone in his pocket, Sigma walked out his bedroom to greet his little brother in the living room.

"Hey there, Tigger!" He greeted, wrestling the boy into a hug while he was in the middle of unpacking.

"Mmph! Sigma!" Atsushi squirmed to slip from his grip. "Stoooop it was hot outside. I'm sweaty. And stop calling me that. I'm not five anymore."

Tigger. A cute childhood nickname. Sigma couldn't quite remember it's origins but he recalled always referring to Atsushi with it when they were children. Special because he'd only ever allow Sigma to call him by it. Though these days Atsushi claimed he was too old for silly nicknames like that.

"Am I not allowed to show my stinky, sweaty brother affection?" He grinned, undiscouraged. "Look at you! I think you grew at least an inch since I last saw you."

Atsushi rolled his eyes but hugged him back, clinging onto him just as tightly. "You said that last month when you visited."

"And I mean it." Sigma said. "I meant it back then too. Boys your age grow fast. I did when I was in high school."

Indeed his brother seemed to look a little more grown up each time he saw him. There was a time when Sigma always stood a full head taller than Atsushi. Now his brother was quickly catching up, nearly at eye level with him. His face was losing that boyish roundness, becoming more slender looking. His body becoming less scrawny and filling out more. Sigma could feel his lean body against him with its subtle curves.

Curves. When had Atsushi gotten those? Sigma mused as he let a hand trace over the shape of his brother's body. Venturing down his side, to his waist, and then his hips. Indeed his brother's body was going through some…changes. This revelation tugged at something odd and unnameable in him, however, he brushed it to the back of his mind.

Yes his brother was growing up…It was getting to a point where words like cute and adorable simply didn't suit him anymore. No. He had heard their mother stop using those words to describe him these days. Atsushi was becoming…handsome. Striking. Charming. And while Sigma agreed he was becoming all those things, that still wouldn't stop him from calling his baby brother cute. Didn't matter how grown up he was beginning to look.

With this on his mind, Sigma couldn't help but squeeze his brother in their hug. Laughing at the half-hearted protest he gave in return about being suffocated.

"Yeah well you sound like grandma when you say stuff like that." The boy said as Sigma finally set him free.

"Well when I moved an hour away I guess I understood why she says those things." Sigma told him. "I hardly get to see you and when I do it seems like so much has changed."

"Your fault for moving so far away."

Their parents had fretted a little when Sigma had moved out for college. Especially to a place so far from home. Their mother had insisted he attend the small college that was only twenty minutes away from their house, however, the program Sigma had wanted was at a university that was over an hour away. She hadn't been happy about it, but their father had insisted they had to let their baby birds go eventually.

She had reluctantly allowed him to go, though only with the reassurance he'd call everyday. He'd been out the house for a few years already and yet it was only recently she had stopped peppering him with kisses and hugs like she hadn't seen him in decades. So Sigma supposed that meant she was finally getting used to the idea of him being away from home.

Atsushi had been similarly stricken. He was a bit younger when Sigma moved out and so not entirely grown out of his attachment to his older brother. Poor thing had felt rather betrayed to the point of tears when he first heard Sigma was leaving. The only thing healing his lamentation was a promise of frequent visits.

These days however, if Sigma ever brought up how much Atsushi sobbed the day he left home the boy would get embarrassed and insist he was exaggerating.

They'd always been close though. Ever since they were young they were always together. Most older siblings probably would've gotten annoyed by their younger always following them around like a shadow. Not Sigma. He always enjoyed how glued to his hip Atsushi had been when he was younger. Clinging to his sleeve or wanting to be in the same room he was. It was cute.

Sigma sometimes missed those moments. Atsushi had grown out of it…at least a little. There were a few times where that old attachment to his big brother surfaced.

"Well when you graduate how about you move in with me?" Sigma suggested. "That way you won't have to hear me sounding like grandma all the time."

Atsushi paused and looked up at Sigma. "You mean that?"

Sigma shrugged. "By that point I'll probably be looking for another place. Could use a new roommate too." Not that Nikolai was a bad one or anything. "Think you can wait about two years?"

Atsushi's eyes lit up with delight. "Yeah! I mean you might have to convince mom but yeah!" He beamed.

Sigma ruffled the boy's hair. "We'll tell her to look at it this way: both her little boys will be in one place at least. And we'll have each other for protection."

"It'll just be the two of us then?" Atsushi smiled. "Just like before you left?"

Ah there was that old attachment resurfacing. Now he wasn't acting too cool to miss his brother.

Just the two of us.

Something Sigma had often said when they were children. A promise shared between brothers. Just the two of them against the world and whatever it threw at them. A life like that sounded nice. With nothing to worry about except his brother.

"Just the two of us." He smiled back. "Just don't spring it on mom too suddenly. She'll cry."

"Right." Atsushi agreed.

"Good. Now let's get you unpacked."

This was going to be a nice weekend.

There was another nice thing about the timing of Atsushi's visit. And that was the company. With his roommate off on some romantic mini-vacation, Sigma had the apartment to himself. And well as exasperated as he'd often get with Nikolai's antics his presence at least made the apartment feel less stagnant. And with his brother here Sigma didn't have to worry about that stagnation haunting him for the next few days.

…Huh. Maybe Maybe Nikolai did have a point in him needing to date—or at least in his crass words…"get his dick wet sometimes". The man truly had no filter. But at least with a partner he wouldn't have to ever deal with being lonely.

Well did that really matter now with his brother here? Asides, he'd dated before and never found much interest in it. Atsushi's company was better than most people's anyway. Even if he could sense the aura of resentment coming from it right now.

"Sigh all you want. You still have homework to do." Sigma said. "I'm not having mom and dad yell at me about being a bad influence."

His back was turned but he could definitely feel the dagger glare aimed at his back. He knew it to be a look of betrayal. Atsushi had come to stay expecting a weekend of nothing but fun and goofing off with his big brother. But instead had been pointed to a table to work on his assignments.

Part of the deal in letting Atsushi spend the weekend here was Sigma making sure he didn't slack off on school work. Had he not sworn such an oath he probably would not have cared. However with it being expected of him to play responsible adult, he'd rather avoid being scolded by their parents.

"You could at least give me some of the answers…" Atsushi complained.

"Then that'd be cheating." Sigma said as he walked over. "Also I wasn't that good at math."

In fact, he had only ever passed any of the classes because he'd been lucky enough to have a friend who'd been excellent at math and willing to dumb it down when tutoring him.

Sliding into the chair next to his brother, he set a bowl of ice cream down. A peace offering and an apology. Atsushi perked up at the sight of it and happily accepted it. He was always easy to win over.

"I do understand enough though to know you're doing your order of operations wrong for that question." Sigma said as he leaned over to inspect his brother's work.

He almost got nailed in the face with a spoon in response.

"Shut up!" Atsushi exclaimed out of embarrassment. "Did I really do it wrong?!" He looked back and forth between his scratch paper and his textbook. Then took to furious erasing his work.

Sigma sat back and laughed. Though as he did so something caught his eye. A mark on his brother's neck, peaking just above his shirt collar. Dark purple and round, perhaps the size of a thumb. It looked almost like a bruise.

"What's that on your neck?" Sigma asked. Someone wasn't hurting his brother, were they?

Atsushi paused and then immediately slapped a hand against his neck to cover it. "Nothing!" Panic was written plain on his face.

Sigma frowned. "Atsushi." He used the same firm tone their mother would always use on them when she knew they were hiding something. It was a warning they'd be in big trouble if they didn't fess up. And while Atsushi certain wasn't in any trouble with him, he still wanted him to be honest.

The boy fidgeted a bit, seeming embarrassed.

"Is someone bullying you again?" He knew when his brother was younger he got picked on at school a lot. Sigma always had to come to the rescue and chase off his schoolyard bullies. They always cowed so easily when a bigger kid came along.

He knew he'd also talked about how some kids occasionally gave him a hard time still. However, he always assured Sigma that it was fine. Though he probably only said that so he wouldn't come to his school causing a scene. A grown man roughing up a few high school punks probably wasn't a good look…

"It's not from bullying." Atsushi told him, hand still firmly clasped over his neck. "I uh…um…It's actually something I consented to I guess?"

Sigma arched a brow. "You consented to a bruise?"

The boy seemed to shrink down as if willing himself to melt away. "It's not a bruise."

"Then what—" The realization hit him then. If not a bruise on his neck then it certainly could only be one other thing. "What are you doing with a hickey on your neck?" The question came out far more shocked than he intended for it.

"Please don't tell mom and dad!' Atsushi panickedly responded.

"I'm not—" Sigma paused and adjusted his tone so he didn't sound too intense. "I'm not going to tell them but they're definitely going to find out if you're not better at hiding it from them."

"Oh um I guess I can wear a scarf or something?" The boy sheepishly lift his head.

"Still too warm for scarves. I'll let you borrow some stuff of mine I don't really wear anymore." Sigma said. "It all has high collars and so should cover it up good enough."

Slowly, Atsushi let his hand fall from his neck. Now he laid them in his lap, fidgeting and squeezing them. "Thanks." He murmured.

"So are you going to tell me who it's from?" Sigma prodded. As far as he knew, his little brother wasn't dating anyone. He always seemed too shy for that sort of thing. However, the big hickey on his neck seemed to imply otherwise.

His brother fidgeted some more, looking ready to slip right out his seat. "I well…I might have a boyfriend now…sort of?"

A boyfriend?!

"What do you mean sort of?" Sigma further questioned.

His brother? Dating? His sweet innocent brother dating someone serious enough to have a hickey on his neck? And that someone being another guy? Not that it was a big deal, Sigma had dated a few guys himself. But something about the idea of a guy ravishing his little brother…well it didn't sit right with him.

"We started dating like two weeks ago. We haven't really done anything but hung out after school a few times." Atsushi confessed. "The coffee shop, the mall, the arcade. I guess you could call some of them dates since he pays for my stuff. But we haven't told anyone about us yet."

And he was blushing. Actually blushing. Light pink dusted his cheeks. Those wide innocent eyes hooded by soft white lashes as he sheepishly looked away. Sigma had never seen him this way…so flustered. It was almost cute—however he was too distracted by the fact his little brother had a boyfriend to admire it.

Sigma stared, feeling shock buzz in his brain like static. "What uh…what's his name? Does he have any siblings I graduated with?"

Atsushi shook his head. "His name is Ryuunosuke Akutagawa. He has a younger sister but I don't know if he has any older siblings."

Ryuunosuke Akutagawa. An unfamiliar name to him. He didn't like it. Didn't like that this was a stranger that he couldn't properly vet. A lot of high school boys were losers or assholes. And his brother deserved something better than that.

"What's he…uh like?" He asked.

Light pink darkened to red on the boy's cheeks. Atsushi was now fiddling with the spoon in his bowl; the contents within was half-melted now. "He's pretty scary at first glance. And…he does get into a lot of fights. But he's really nice I promise!" He explained. "I think he only gets into fights when he's defending someone else. It's sort of how we met.

"The guys from the basketball team were giving me a hard time again. They cornered me after school and Ryuunosuke came to me rescue." He smiled. It was a smile that Sigma had never seen from him before. The type of smile that could only ever be accompanied by warm feelings and butterflies in the stomach. "It was pretty scary seeing him pummel some of them into pulps. Thought I was next when he looked at me. But he just asked if I was okay and helped me up. He even offered to walk me home."

Great…his brother was dating one the school delinquents. Something twisted in Sigma's stomach. It felt like someone had taken their nails and was using them to pinch the tender flesh of his organs. And the feeling only intensified as Atsushi went on about this Ryuunosuke Akutagawa. About how walks home turned into after school hangs outs at the park. And those turned into dates at the cafe. And that turned into holding hands. And holding hands turned into a first kiss secretly had in the boy's locker room. And that first kiss had turned into something more heated and sloppy in a bedroom when mom and dad weren't around.

Atsushi hadn't mentioned that last one but Sigma could glean it from the mark on his neck. One didn't get a hickey from just shy little pecks. Something made his blood turn hot at the idea of some random, horny teenager pinning his brother against his bed. Hands roaming where they shouldn't as they sneakily snaked under clothing. Hips grinding against him like an unneutered dog. A greedy mouth kissing him so deeply that every little noise he made was swallowed—

"He reminds me a lot of you actually."

Sigma blinked, torn from his thoughts. "Huh?" He absently responded as the heat in his veins cooled.

"Ryuunosuke sometimes does things that remind me of you." Atsushi smiled. "Like he's really protective of me for example. He doesn't like it when people mess with me and always comes to my rescue when it happens. Reminds me of how you used to do the same for me. I think that's part of why I like him so much. He makes me feel safe…"

"He makes you feel safe because he beats people up?" Sigma leaned back in his chair.

"No!" Atsushi blushed again. And Sigma didn't think he'd ever seen his brother blush so much before. "He does other things for me and he's really nice about it. He cares about me being happy and that's what makes me feel safe. And that's what made me think of you cause you'd always do the same for me."

That…did soothe some of his dislike. But.

"I'm the better one at keeping you happy, right?" Sigma smirked.

The remark was childish and he didn't know what provoked him to say it. But it had tumbled from his lips before he could stop himself. And the only way he saved himself from feeling embarrassed was by smiling it off—treating it as lighthearted teasing. Only the pinch feeling in his gut didn't make it feel very lighthearted.

"It's not a competition." Atsushi told him.

"It is when it involves your wonderful older brother and the person you're frenching with in the locker rooms."

"We didn't—" Atsushi sighed. "Well if you want to make it a competition then…my boyfriend doesn't make me do math homework during what's supposed to be a fun long weekend."

Boyfriend.

For some reason hearing that word caused a twinge of annoyance in his chest.

"I gave you ice cream." Sigma declared.

"Ryuunosuke also gets me ice cream." Atsushi countered smugly. "In fact, he regularly takes me to that one ice cream place you used to take me after school."

Another twinge of annoyance. "Our ice cream place?" A favored spot he and Atsushi frequented before he left for university. They went there so often that the owner knew them well. That was his and Atsushi's thing. It was a special place for the two of them and for a stranger to be invited into that…Well it felt like a betrayal—a violation.

"Yup and he gets me whatever I want." Atsushi continued.

Sigma wrestled internally, shoving down a rather unpleasant feeling bubbling up in his chest. He smiled but could still taste the feeling in his mouth as bile. "Well did your boyfriend," His lips stubbornly didn't want to form the word. And it almost came out as a stutter, "rent your favorite movie and its sequels with a plan to marathon them with you all night?"

Atsushi perked up and Sigma knew that was a sign he was victorious with that one-up.

"Did you really?" He asked.

"Yep. All three." The simmering feeling in his chest died down, replaced by pleasant smugness. "Got popcorn and snacks set up for it. When you finish your homework we can kick off our fun weekend with a movie night. Sound good?"

Atsushi frowned at hearing he still had to do homework but after seeming to contemplate it further he found the terms acceptable. "Okay fine. I guess you're the best. For now."

"Hey, your line is supposed to be 'Of course! You'll always be the best in my heart!'" Sigma feigned indignance. Though it wasn't all that feigned…

"Yeah, yeah." Atsushi waved him off.

For now.

He knew it was meant to be a tease but Sigma didn't like the idea of possibly being replaced as his brother's favorite person. It sent a twinge of something through his chest. Panic? Worry? Some other deep and rotten emotion?

Had Atsushi really gotten to an age where he didn't need his brother anymore?

Sigma coiled his hands into fists, nails biting into his palms. "Anyway ah…" Suddenly his throat felt very dry. "Finish up with that as quick as you can. We don't want anything eating into our movie time, alright? I'll get everything ready."

Atsushi merely nodded in response, focused intently on his homework now that he had incentive to get it done. And deciding to leave him in peace, Sigma got up from the table to let him work. Though as he did so his gaze couldn't help but wander back to his brother's neck. Lingering there on the dark mark peeking out of his collar.

That unnameable and unpleasant feeling simmered back up in his chest and he looked away. Yes he definitely would have to get Atsushi something to cover that up…

It had been a while since the two of them had enjoyed a good movie night. Usually something they had only ever gotten to do on weekends whenever they didn't have school. So tonight felt rather nostalgic. Or it would have if Sigma didn't feel so distracted.

One moment he'd be focused on the movie and then his mind would drift. It was in the way one's mind only ever drifted because they were anxious about something but could do nothing about it. It was like a constant static at the back of his mind.

The revelations about today left him feeling…troubled? Was troubled the right word? He didn't know—but he did know that his insides had felt like they were squirming around within him all day.

His brother was seeing someone. Dating.

There was someone else in his life now that he enjoyed hanging with. Someone else who took him special places that he enjoyed. Someone else who made him smile and laugh. Someone else special.

Someone he shared intimate moments with that Sigma could never give him. That much was plain from the hickey stamped onto his brother's neck. An ugly mark marring the skin there and who knows where else…

Sigma cringed at the thought. He had originally assumed the mark could have only come from some sort of heated make out. But what if he had gotten it…another way?

No. That couldn't be possible right? There was no way his brother was having sex, right?

Someone else holding him close. Touching him. Hands and mouth ravishing every inch of skin. Making him whine and arch against the bed as they—

Sigma felt his organs twist violently at the thought. God no. He didn't want to think about it. He didn't—

"Hey." Atsushi nudging him jolted him from his torturous thoughts. "Pause it for me. I want to get something to drink."

"Huh?" Sigma hadn't realized he'd also been clenching his jaw until he felt a dull ache in his teeth. "Yeah sure." He picked up the remote, pausing the movie.

He watched as his brother scampered off to the kitchen. Were there other lascivious marks hidden under his clothing? Telling the story of how someone ravished his brother's body? Sigma forced himself to tear his gaze away, focusing back on the frozen screen of the TV.

His jaw clenched painfully as he tried and failed to bat away the twisted images that tormented his mind. But he had always been cursed with a creative mind. A persistent one as well.

"You have so much booze in here!" Atsushi called, briefly rescuing him from the torment of his own mind. "Can I have one?"

The question brought a bit of levity to the chaos that wracked him. Sigma couldn't help the small laugh that slipped from him. "Mom would kill me. No." He said. "Asides most of that is Nikolai's and I don't think he'd appreciate it either. Even if he did it's strong stuff—too much for you."

For some reason his roommate's taste in alcohol was the type of stuff that made you feel like you took a truck to the chest. Or at least made you wish a truck had hit you when you woke up the next morning with the hangover.

"Come on." Atsushi complained. "I'm not a little kid anymore. I can handle it. I've had some before!"

Sigma frowned at that. Since when did his little brother drink? He was learning all sorts of new developments with him today. "From who?"

A pause. "Never mind I'll just get a soda."

No admission of who it was. Sigma took that as a sign he wouldn't like the answer. And for the sake of his already strained sanity he didn't press further.

Atsushi soon returned with drink in hand—Sigma made sure it was indeed soda—and flopped back down on the couch next to him. And once certain the boy was settled in, he pushed the button to resume the movie.

The brief distraction allowed Sigma to push his unpleasant thoughts to the back of his mind. It was better to focus on the moment now. His brother was here and spending time with him. He shouldn't be dwelling on anything else that might ruin this moment.

He felt Atsushi suddenly press up against his side. "It's cold." The boy complained. "Can you turn off the AC?"

"Weren't you complaining about it being hot earlier?" The weather had been rather warm lately and it often left the apartment feeling stuffy. Sigma had turned the AC on when Atsushi had commented feeling dizzy. "Asides, you're only cold cause your drinking something cold now and you've stripped down."

Atsushi had changed from his school uniform, dressing down into something more comfortable. Shorts and a tank top. Said tank top was a little too big on him—in fact Sigma recognized it was an old one of his— as one of the straps kept slipping down his shoulder. The shorts he wore were cut high, stopping an inch above the knee. Though Atsushi sitting with his legs curled up on the couch made the shorts ride up higher.

"That was before I knew your apartment could become an ice box." Atsushi said, rubbing his legs together in attempt to warm up. The movement drew Sigma's eye, his gaze tracing his slender legs all the way up to his barely covered thighs.

"I could warm you up?" He use could use his hands. Run them along that soft skin. Chasing away cold…and the touch of anyone else. Sigma blinked the thought away. What was wrong with him? "It's still too warm outside to turn the AC but I think I have a blanket in the closet. Would that help?"

Atsushi looked thoughtful then shook his head. "No I think I'll just mooch off your body heat. Much better than a blanket anyway." And he snuggled closer. So close that Sigma had no choice but to wrap an arm around him. "Just like old times, right?" Atsushi said as he rested his head against Sigma's chest.

Sigma's heart skipped a beat. "Yeah."

Old times…Like when they were little children who would fall asleep curled up on the couch with each other. That was when they were each other's world. When nothing else matter to them but each other. Those were the days when his sweet baby brother depended on him for everything. Safety, support, happiness.

The twisting feeling in his guts returned again.

Fuck…What was wrong with him? Today was supposed to be a nice day and yet he felt like a wreck on the inside. And was all because—

Because—

And something finally snapped in him underneath the weight of everything piling up within him.

His baby brother wasn't quite a baby anymore…

He was growing up on him fast. He had new wants and needs and curiosities. And they all led away from Sigma. The idea that Atsushi might not need him anymore—the idea that he might seek that happiness and comfort from someone else

…Well it made something shrivel up inside him.

He couldn't stand the idea of this Ryuunosuke—this usurper—coming in to dethrone him from his place in his brother's life. Could stand even less the idea of him defiling his brother. It would start with hickies. And then it always heated up from there. Kissing led to groping. Groping led to wandering hands removing clothing. And that led to the twisted image of his brother being held down and used by someone.

He knew how teenage boys could be about sex. How pushy and perverse they could get. Atsushi wasn't like that of course, but there were plenty that definitely were. Practically dogs that humped anything that moved. And Sigma didn't have to meet Ryuunosuke to know he was not exception.

He would not let a dog take his baby brother from him. Only he knew how to keep Atsushi happy. Only he knew how to take care of him. Only he could ever truly love him.

"You have no idea how special you are to me." Sigma found himself saying as he pulled Atsushi tighter against him.

Atsushi yawned, trying to blink away his drowsiness. They had been watching movies for a while. It was getting late. "Of course I do. I'm your little brother. I'm supposed to be special to you." He smiled.

Oh he was so precious. "And what about me?" Sigma ventured. "As your big brother, aren't I special to you?"

"Mhm. You've always been there for me, Sigma. Especially when mom and dad got busy. I knew I could always come to you for anything." He snuggled closer, practically crawling into his lap. "You always cheered me up when I was sad. And kept me safe when I was scared. Without you in my life I don't know what I do. You're the most important in my life."

That made his heartbeat quicken. "Most important huh?" He looked down and brushed at the boy's hair. "More important than dad?"

Atsushi smirked up at him. "Yeah."

"And mom?"

"Mhm!"

His fingers drifted down to brush over Atsushi's cheek. "…And Ryuunosuke?"

At the mention of his new boyfriend, Atsushi suddenly sat up. And Sigma grimaced to himself at the loss of his warm presence. Idiot. He scolded himself.

The proud smile had fallen from his brother's face. Replaced with an expression Sigma hoped was thoughtful consideration and not discomfort.

Perhaps he had pressed too hard? Perhaps there truly was someone who could dethrone him as his brother's favorite person and there was no way to reclaim that role? The thought pinched at Sigma's insides. And the longer Atsushi took to answer the more rotten he felt within.

Had he really lost his brother?

"He's my boyfriend." Atsushi began, and Sigma despised the reminder. "But…you're my brother. He can't make me feel the way I do when I'm with you. So of course you're more important than him. Sigma, what's going on? Do you…not like me dating or something? I promise you he's a really nice guy."

And Atsushi looked up at him with sweet and gentle look of his. It was a look Sigma knew he only ever had for him. He grew up for years knowing it. So warm and full of a special love just for him.

Sigma's hand cupped against his face, caressing the warm skin there. There was something irresistible about those eyes of his. Just looking into them made Sigma want to melt. The thought of anyone else being held by that tender gaze ached.

He wanted to remain the only one Atsushi looked at like that. He wanted to be the only ever that Atsushi needed.

"I just…" He softly began. "Can't stand the thought of losing you to someone else."

His thumb brushed downward, over the boy's lips. Was it okay for an older brother to feel this way about his younger brother? Was it okay for him to want to be the only one Atsushi ever loved? He was just being protective wasn't he? He just wanted to keep him safe from other people who would hurt him.

So it had to be okay…when he leaned in and kissed him.

Atsushi's lips were soft. Warm. Pliant against his own. His scent waft over him; toothpaste and and honey-scented soap. He wanted to be wrapped up in all of it forever.

And perhaps it was his imagination. Perhaps it was him falling too deeply into his delusions…But he thought he felt Atsushi—just very slightly—kiss him back.

He pulled away, slowly and carefully, not wanting the kiss to end too soon. "You're the most important person to me as well." He whispered.

Atsushi stared back at him with wide eyes. Confusion. Shock.

"Sigma I…" His voice was soft. And was that a tremor of fear there as well?

Sigma felt a twinge in his chest at the thought.

"What is it?" He asked just as softly. "What's wrong?"

"I just wasn't expecting that." His cheeks blushed pink. "Being kissed."

"Are brothers not allowed to show each other affection?" Sigma asked.

Atsushi chewed on his lip, fidgeting. "They are but a kiss is different. It's something special shared between two people who care a lot about each other." He stumbled over his words awkwardly. As if wanting to say something else but was too shy to actually say what he meant.

"And I said you were special to me." Sigma brushed his thumb over blushing skin. "And I care about you a lot. You care about me too, right?"

Atsushi's hand moved to rest atop his. "I do. Of course I do." He murmured. "I just…" He seemed to be fishing for more to say. However, the sentence trailed off.

Sigma was also quiet for a moment. Was he being fair to Atsushi? He searched the boy's face for any sign of discomfort. Surely if he hated it then he would've run away by now wouldn't he?

"Did you not like it?" He asked eventually.

Atsushi didn't answer at first, seeming to consider his response. "It wasn't bad." He fidgeted again. "It was just different. Ryuu doesn't kiss me like that."

Ryuu.

Ah…he had a little nickname for his supposed boyfriend. It made it feel as if someone were sawing through his guts.

"How does he kiss you?" He found himself asking.

"Not like you do." Atsushi looked away, suddenly embarrassed. "He's more aggressive? No—that makes it sound bad. He's not gentle about it…n-not in a bad way. It's just when he kisses me it feels less like a kiss and more like he's trying to swallow me."

He paused and seemed to turn redder. "That sounds bad. That sounds so bad." He covered his face. "Ryuu's not a bad guy but he's just—"

"Do you like it when he kisses you?" Sigma interrupted, watching him carefully. His gaze flicked to the dark mark on his brother's neck and his fingers traced down to brush over it. He could feel Atsushi's pulse racing under his fingertips. "Did you like it when he gave you this?"

Atsushi peeked through his fingers at him. "He's…my boyfriend."

"That's not an answer."

The boy was quiet again.

Adter several seconds ticked by he eventually he let his hands fall from his face. "He's not a bad person." Atsushi said and then seeming to realize that didn't answer Sigma's question either, he spoke again. "Sometimes I do wish he'd be gentler though."

That soft gaze lifted to meet Sigma's again.

"You like it gentler then?" He asked.

Quiet again.

"Did you like it when I kissed you?" As that was a question Atsushi hadn't actually answered either.

His brother chewed his lip and then slowly nodded. "Yeah…a little." He softly confessed.

Had it been his imagination back then? Or had he really felt Atsushi lean into the kiss. He had to know.

"Do you want me to kiss you again?"

Sigma thought his heart might burst out his chest as he waited for any answer. He hadn't realized it'd been racing until now. Every second of silence that passed made his chest ache as it felt his heart was about to fly right out of it.

"We're brothers." Atsushi eventually said, his voice was soft.

"Is there anything wrong with that?" Sigma asked. "Two brothers loving each other?"

Another painful pause.

And Sigma told himself he could handle it if Atsushi rejected him. He could handle it if his brother ran away from him now and refused to come back. A lie of course. It would destroy him. But perhaps if he lied to himself hard enough he'd believe it. He'd believe it and swallow every disgust and fear at the idea of someone taking his baby brother away for the sake of Atsushi's happiness.

Finally after what had felt like eternity in Sigma's whirling mind, Atsushi spoke. "No I guess not. So then…" He shyly came to a decision. "Can you do it again? Can you…kiss me again?" He shuffled closer.

And Sigma obliged without hesitation, cupping Atsushi's face and pulling him into another kiss. This time he was very much certain Atsushi leaned into it, actually kissing him back. Even surprising him with a whine of protest when he moved to the break the kiss.

"More…" Atsushi whispered. And Sigma was of course too weak to resist that sweet request.

He kissed him again. Deeper. Hotter. Every second of kissing him felt exhilarating. He'd kissed others before. It always felt nice but not like this. Never like this. His heart never raced like this with anyone else. He never felt starved like this for anyone else.

Sigma pulled Atsushi into his lap and the boy's arms seemed to instinctively wrap around him. He fit so perfectly against him. Better than anyone else ever had.

Sense said he shouldn't want his own brother like this. It told him that he was doing something wrong. Selfish. Perverse. However, he didn't like the sound of sense. Didn't like how to it tried to make him placid to his brother being stolen away from him.

Spurred on by this, Sigma pushed Atsushi down against the couch. And his brother's legs obliging wrapped around his waist, pulling him in closer. That sent a thrill through him unlike any he felt. Sigma greedily deepened the kiss, Atsushi's lips parting for him, yielding to him as his tongue slipped in to taste every sweet noise that came from the boy.

Starved for more, Sigma's hand slipped under his shirt, gliding across smooth, flushed skin. He wanted to reclaim every inch of him, steal back every part of him someone else touched.

In responses he felt Atsushi squirm beneath him. "What's wrong." He breathed, pulling back. Had he gone too far?

His brother's face was flushed, his cheeks were bright red and his eyes were glassy with desire. God he looked so cute like that. "Your hands are cold." He panted.

Sigma paused. "You want me to stop?"

He should. If he stopped now then he prevented himself from crossing the point of no return… But also if he stopped now then that meant he'd be letting someone else take Atsushi from him.

Before he was given the chance to lament this, Atsushi wrapped his arms around him and pulled him back in "No." He murmured. "Keep going. I'll…I'll warm you up."

God he was adorable.

Sigma kissed him again. This time against his cheek. Then along his jaw. His Adam's apple. And down along his neck, stopping just above that ugly mark there. The place where someone else dared to try to claim his brother.

Sigma's lips brushed over the mark and he felt Atsushi shudder in response. "I hate the idea of someone else having you." He admitted aloud. "All day it killed me knowing he touched you. Knowing that his hands were all over you. I wish I could take you back from him…You're my little brother. You should only be mine."

"Then do it…make me yours." Atsushi softly replied.

Sigma abruptly lift his head and looked down at his brother. Oh how he loved seeing him like this. So innocent and vulnerable looking beneath him. He took him by the chin, brushing his thumb over those pink parted lips.

"I don't think you understand what you're inviting me to do to you." He gently warned. "You have no clue how badly I want you and how much I've been holding back."

Desire felt like molten lava in his veins. And a few kisses certainly weren't enough to help cool that heat. He wanted more. He wanted Atsushi in such a terrible way a brother shouldn't. And yet he couldn't ignore it. Not anymore.

"I do understand." Atsushi insisted. "I know what you want. And I…I want it too."

He wants this too…

Did he really? Or had Sigma gone too far and simply corrupted his sweet, innocent brother with his perverse wants? He searched Atsushi's face for any sign of fear, however, he only saw his own desire reflected back at him.

He really wants this. He really wants me.

Sigma's heart fluttered. "Curious to see if there's something else I do better than your little boyfriend?" He couldn't help himself. His dislike of this stranger—who dared to defile his brother—was potent.

Atsushi abruptly looked away, seeming shy. "We uh…never…" He trailed off as if embarrassed to say the actual words.

That sent a wave a relief flooding through him. He was glad. No one had placed their filthy hands on his brother. Though there was also a thrill that shot through him. The thrill of knowing he'd be his brother's first. Knowing that anyone else after would only ever be compared to him.

"Good. Teenage boys are terrible of sex." Sigma murmured. They all only knew how to stick their dicks in a hole and move a little. They didn't understand true pleasure. Clumsy high school hook-ups taught him that lesson. "They don't know how to make their partners feel good. Not like I do."

He could feel Atsushi shudder. "I want you to make me feel good." He whispered. "I mean it. I really want it to come from you, Sigma." He seemed to blush redder. "Honestly the thought of it being anyone else is kind of scary. But…if it's you then I know it'll be alright."

That was enough for Sigma. Leaning forward he kissed him again and got up. "I'll be back." He promised when he saw the puzzled look on Atsushi's face.

It was only a quick trip to his room. Pulling open his bedside drawer he retrieved a tube of lube—embarrassingly unopened…maybe Nikolai had a point about him needing more action?—and a few condoms. And then he returned back to the living room couch where his brother waited.

"Take your clothes off for me." Sigma instructed.

Though he did look rather charming with his clothing rumpled like that. His shorts were hiked up and both straps of his tank top hung off his shoulders. It caused said tank top to dip down, showing off a flash of one of Atsushi perky pink nipples.

"Is my big brother not going to undress me himself?" Atsushi taunted. "Thought you wanted me badly?"

Now where had that boldness come from? Regardless, Sigma had found it endearing. And so he obliged, stepping up to the couch and pulling Atsushi forward by his legs. He then promptly pulled both his shorts and underwear down in one fluid motion, discarding them on the living room floor.

"Cute." Sigma breathed as he admired his brothers little cock between his blushing thighs. Atsushi wasn't very big, he noted. Both in terms of length and girth, perhaps a bit below average for someone his age. But that didn't matter to Sigma; the only plan he had with his brother's cock was to leave it blushing and dripping. Smirking, he reached down and ran his hand along its length.

Atsushi jumped in response. "Cold." He complained.

"Oh? What happened to you warming me up?" Sigma teased back. "But fine if my hands are too cold then I have something much warmer that'll put you in the mood."

And he lowered himself to his knees, keeping eye contact with his brother as he did so. He looked so cute with the expression of shy wonder on his face. But there was another expression Sigma wanted to see on him.

He laved his tongue along the length of his brother cock. That elicited a sharp noise from Atsushi. His face went red and his eyes widened in pleasant surprise. "Sigma!" Oh that was such an adorable whine in his voice.

Encouraged by the reaction, Sigma swirled his tongue around the tip, already tasting pre-cum beginning to leak from it. And the little mewls he got in response were music to his ears. His baby brother was a sensitive one. Made sense. He was a sweet little virgin.

"That feels…ngh!" Atsushi's voice trembled.

Sigma took his entire length in his mouth, reveling in the way the boy jolted. All of Atsushi's reactions to it were so sweet. Wiggling and squirming and bucking his hips up to fuck further into his mouth. This of course spurred Sigma on further.

He bobbed his head along his brother's shaft. Teasing all the way up to the tip—making Atsushi squirm even more—and then dipping back down to his balls. His tongue lapping at every inch of him as he did so.

Atsushi rocked his hips, desperate for more stimulation. "Hn! Sig-Sigma—ah!" His named tumbled from his brother's lips, falling a part into a string of moans. "Big—big brother I'm….I'm gonna—ngh!"

Sigma could feel it—taste it. How close to the edge his brother was. And he was tempted to push him over that edge. He wanted to taste Atsushi's first orgasm caused by him. But the night was long and there was still so much he wanted to do.

Sigma let Atsushi cock pop out his mouth. It was glistening and flushed pink, pre-cum was dripping from its tip.

"Look at you." He breathed as he wrapped his hand around the wet member. "Hard for your big brother. Did it feel good?"

Atsushi looked as if he were in a daze. Eyes glassy and face rosey. "Yeah…" He managed with a trembling voice. "I liked it."

"Good." Sigma stood and pressed a kiss against his lips, loving the way he so eagerly kissed back. And he could feel the eagerness of his own cock straining against the confines of his pants. Wanting. So badly wanting.

It was also a reminder that he was still dressed. Rather unfair to his little brother, especially when he had already complained about being cold earlier. And so in between searing kisses he fiddled with his shirt, plucking at the hem until he finally managed to pull it over his head and toss it to the floor. His hands went to his jeans next, unbuckling and unbuttoning them to free his aching arousal.

Oh and he definitely ached. When was the last time he had sex? Far too long…Sigma sucked in a breath as he ran a hand along his erect member.

He caught sight of Atsushi's shy expression and smirked. "This your first time seeing someone else naked?" He teased.

"Maybe…" Atsushi mumbled. God he looked so adorable we he blushed.

"Like what you see?"

"Y-yeah."

"So nervous." Sigma murmured as he brushed his fingers down Atsushi's thigh. "You know I'm not going to hurt you right?"

"You're sure talking a lot for someone who wants me badly." Atsushi replied, displaying that earlier boldness again. "H-hurry up and put it in."

And Sigma couldn't help but laugh. "Impatient aren't we?" He said. "Alright. If my baby brother is so eager for me to fuck him, I won't keep him waiting."

He slipped back onto the couch and pulled Atsushi's hips towards him. Not even bothering to hide his own eagerness as he grinded his cock against the boy's bare ass. He reach for one of the condoms and brought it to his teeth to rip open, keeping eye-contract with his brother the entire time. Sigma wanted him to see the lust in his eyes. Wanted him to know just how badly he want this. And it thrilled him to see that same want staring back at him.

He was just about to slip the condom on when Atsushi stopped him.

"Wait." He said. "You don't…you have to use one. It's fine."

Sigma arched a brow. "Wanna tell me why?" He had intended on wearing one for the sake of Atsushi's comfort. It was his first time after all.

His brother brother looked hesitant—almost embarrassed. In fact it seemed to take him a moment to find the courage to respond. "It's just…I want to be able to feel you." He admitted. "I want to feel it when you cum."

Oh.

Oh fuck.

That did something to Sigma. Made something carnal stir in him. His brother wanted to feel him fucking inside him raw. He wanted to feel his cum spilling into him. Wanted to feel Sigma breeding him.

He bit his lip at the thought.

"I-is that okay?" Atsushi sheepishly asked when he hadn't responded.

And Sigma chuckled, placing a hand on Atsushi hip and using the other to dribble lube on his cock. "Oh I'm happy to give you whatever you want, Tigger."

"I-I told you to stop calling me that. I'm not a little—ngh!" His complaint was cut short when Sigma nudged the head of his cock against his tight entrance.

"I know you're not a little kid anymore. You've grown into such a pretty boy." Sigma breathed as he teased his head around Atsushi's entrance, smearing slick pre-cum there. "But you'll always be my baby brother. And so that means I'll always take good care of you."

He pushed in. Slow and deliberate. Making sure Atsushi felt every inch of his his girth. Reveling in feeling his brother stretch around him. God he felt so good. So tight. He was so fucking tight. Warm walls squeezed greedily around his cock, inviting him deeper.

"Sig—ah!"Atsushi's voice rang off the walls. A sweet wail of surprise and pleasure and innocence lost. His back arched off the couch and his fingers grasped at the fabric. Every squirm and wiggle of his hips made his walls flutter around Sigma's cock, which only spurred him on.

"Fuck Atsushi." Sigma groaned once he bottomed out. "Barely started and you're already try to squeeze me dry. You feeling good though?" He panted, checking in on his brother.

The boy was staring up at the ceiling, looking as if he were seeing stars. He probably was. It seemed to take him a moment to register that Sigma was talking to him. He blinked. "Ah…it feels like so much. It's too much—"

"You can handle it though." Sigma murmured. "You said you're not a little boy anymore. So you can handle your big brother's cock, right?"

"Yes." He whined. "I…Yes…Please I want it. I want you…"

Hearing his brother beg for him sounded so hot. He loved that little whine in his voice that pitched it up. What other pretty noises could he coax from him?

"I can tell how bad you want it. Just look at you." Sigma wrapped a hand around Atsushi cock which had pearly white liquid leaking onto his stomach. "I just put it in and you're practically cumming already."

Embarrassment seemed to wash over Atsushi. "I-I couldn't help it."

Cute. That sheepish expression looked good on him right now.

"It's alright but…this isn't all you're going to give me is it, little Tigger?" Sigma swiped his fingers across the tip, smearing the sticky substance onto them. Locking eyes with Atsushi, he lift his fingers to his mouth and licked the cum off them. That got him the reaction he wanted: he could feel Atsushi squeeze tighter around him. "I hope not. I was intending on making a mess of you tonight."

He moved his hips back and heard Atsushi actually whimper from the absence of his cock filling him. And as a good older brother, Sigma could only oblige in giving him what he was aching for. He plunged into him, feeling his brother's tight heat squeeze around him again.

O-oh he felt amazing!

And the feeling seemed to be mutual from how Atsushi squealed when he put it back in. The boy's back arched off the couch, raising his hips and allowing Sigma to plunge deeper.

"You're…being so good for me." Sigma groaned as he began to thrust his hips.

Sex with other people had always felt good. But with Atsushi it felt different—it scratched at something within him just right. Atsushi felt so needy. With each thrust inside he'd buck his hips up as if trying to fuck Sigma back. Between his little whines and moans he could hear him attempt to whimper his name only for it to fall a part into a string of sweet and salacious noises.

Sigma dipped down to taste those delicious sounds. Taking advantage of his brother's parted lips to kiss him, greedily lapping up every little mewl and whine that escaped his throat. And it thrilled him to feel Atsushi's arms wrap around him, holding him close.

Their bodies pressed against each other, flushed skin against skin, ragged breaths mingling with one another. He could feel his brother's harden cock rub against his stomach as he fucked him. Slick from the pre-cum dripping from it. He could feel his nails digging into his shoulders, clinging to him tighter ever time he drove his shaft home inside him.

He could hear it in his voice every time he rutted against that precious spot deep within him. Atsushi's whines would pitch higher and his hips would move against Sigma's as if trying to invite him further in.

"Deeper?" Sigma breathed, surprised at how difficult it was for him to form words of his own. Was he losing himself that much? "You want…it deeper?"

"Hn! Ah—Hmph! Ye—Yes!" Atsushi struggled to respond. "H-harder…Harder! I want—ngh! Deeper!"

God he loved hearing his sweet brother begging him. Pleading. And hearing his voice tremble. Oh Sigma couldn't resist anything about him.

He ground his hips against the boy's ass, adjusting his rhythm so he could fuck into him deeper. And oh Atsushi's reaction was wonderful. His voice rang louder—perhaps louder than he should have in this little apartment; Sigma had neighbors after all. But that was the furthest thing from his mind right now as he continued railing his little brother into the couch.

"Good…boy. Fuck you're so good to your big brother." Sigma panted. "I love you. I love you so much!" His pace picked up.

Harder.

Deeper.

"Sig…Sigma—Ah!"

More…More…

One final thrust sent his brother over the edge.

The sound that slipped from Atsushi was pure and carnal. He came, his pinned cock dribbling against both their stomachs. He was beautiful when he came. His cheeks were rosy pink and his eyes seemed to dazzle. And that on top of his brother clenching around him is what brought Sigma to the edge as well. Groaning, he hilted inside and came himself, spilling his seed inside his sweet little brother. Spasming walls ensuring that he was drained of every last drop.

After riding through their orgasms, the two brothers laid there for a while. Panting and sweating and tangled with each other. Pleasant tingles danced across Sigma's skin. His mind felt as if it were floating amongst the clouds Everything felt so nice. Maybe Nikolai had a point? He'd been in desperate need of some good sex?

Smiling dreamily, he looked down at Atsushi who also appeared drunk on the afterglow. "Are you alright?" He asked as he brushed at his hair. It had become rather messy in their coupling and Sigma had no doubt he looked just as tousled.

Pale white lashes fluttered as if Atsushi were being pulled from a dream. "Y-Yeah." He leaned into Sigma's touch. "Are you?"

And Sigma almost wanted to laugh. He was so sweet.

"I feel wonderful." He told him. "You were so good."

"Oh." Atsushi blushed. "You…You were too."

Humming in satisfaction, Sigma cupped his cheek and leaned down and kissed him. No matter how many times he did so he always loved that sweet softness of them. Everything about Atsushi was so soft and so sweet.

A grunt from the boy made him stop and pull away with a quizzical expression.

"The movie!" Atsushi exclaimed. "We missed the rest of it!"

And indeed a glance at the screen showed the credits rolling accompanied by climatic music. Sigma had been so adsorbed in Atsushi that he had completely forgotten about it. Oops.

"We missed the good part too!" Atsushi lamented.

That time Sigma did laugh. God, he loved him.

Wrapping his arms around Atsushi, he shifted to carefully reposition so his brother was lying atop him. He'd worry about getting the two of them cleaned up later, right now he just wanted to bask in the pleasantness of it all. Atsushi's warm weight, the loving look in his eyes, the feeling of him still fluttering around his cock sheathed inside.

Everything felt nice right now.

"It's a long weekend, remember? We can stay up late and watched what we missed." He reassured. "How's that sound?"

Atsushi perked up at that. "I'd like that."

Sigma smiled and his eyes drifted flicked to the dark mark on his neck again. Though this time it didn't feel him with rage. Rather…a sense of smugness. A silly little mark would fade, he realized. But the pleasure of his brother's first time never would. An invisible mark that said Atsushi was his.

Though of course that was that small sliver of jealousy at the back of his mind that demanded the unsightly hickey be covered up. Tomorrow morning he'd have to give Atsushi something to do so.

Until then, he just wanted to revel in this moment.

Combing his fingers through Atsushi's hair, he encouraged him to lay his head down against his chest. "Relax. I've got you."

And Atsushi hummed pleasantly as he laid against him. Watching as Sigma took up with remote to rewind the movie.

"Hey, Sigma?"

"Hm?"

"I love you too."

His heart skipped a beat. Smiling, he wrapped an arm around Atsushi, relaxing against the cushions of the couch.

This was definitely going to be a nice weekend.
