Synchronized Heartbeats

Chapter 10: Baby Fever

It wasn't often that Gou had trouble sleeping. Of course her first time would involve her brother. She'd already given him so many of her precious firsts, so why not something like this? How frustrating!

It was past two in the morning and the night was stuffy and hot despite her open window. It wasn't the cicada noise in the background that kept her awake. She was exhausted enough to knock out for a full night's rest. If only she wasn't so concerned about the absence of her brother. He had yet to come home and their mother wasn't so worried. Yet, Gou didn't believe Rin ever stayed up this late for fun. What if something had happened to him?

"He's a boy, he can take care of himself. And your brother is not the kind to look for trouble." Mrs. Matsuoka had said when Gou insisted they call him to demand he return home.

She threw her pillow over her face.

How insufferable! If Gou was in her brother's position, she'd hear no end of it from their mom. Screw these double standards. It was unfair how Rin always got special attention just because he was a star athlete and she—no. Stop it, Gou. Just stop.

Gou took a deep, muffled breath beneath her pillow. She was the one being unfair. She was unfair that time they argued and she was being unfair to her brother now. It did no good for Gou to search for reasons to be angry at her brother when those reasons weren't even justified. Honestly, Gou didn't even know why she was mad at Rin. He truly had done her no harm to elicit such a rude reaction. She knew she needed to apologize for being unreasonable and moody the past days. There was no excuse for her cranky attitude towards him, especially when he'd been right. He was only being logical when he said it wasn't the right time to have sex.

Tomorrow, at the beach, she'd talk to Rin privately. Gou could never forgive herself if something happened to Rin and they'd never resolved things first.

She had planned to apologize to him. Honestly, she did. For the past few days, Gou had been trying to muster the courage to look her brother in the eye and apologize. To tell him that he was right; she had been aching to have sex with him regardless of the risks or circumstances. Her brother was only being careful while Gou was the one having pregnancy scares and such. But it was so painfully difficult to look Rin in the eye, admit she was horny for him, and then try not to kiss him right after. She never realized how much she would miss those lips of his.

His lips…

Lifting the pillow from her face briefly, Gou absentmindedly touched her fingers to her mouth.

When her brother had come out of the pool as the first place winner, Gou had automatically jumped to her feet, clapping hard and shouting in celebration. The crowd had gone wild when Rin won the competition with a record-breaking 16.39 seconds for the 50-meter butterfly. Rin had only managed to shoot Gou a look before he was stolen away to the side for the announcements. Then, as soon as the little award ceremony had finished, Gou had tried to reach her brother, only for him to be swarmed by reporters. She had waited outside the large group of fans and reporters separating her and Rin. But Gou had never felt so far from her brother as she did then. Hearing the girls squeal and fawn over him only soured her mood even more and Gou had asked Sousuke to take her home.

Of course, Sousuke had told her that there would be a celebration of Rin's victory, but Gou wasn't in the mood to see her brother and not be with him as she wanted to. So after a few more unsuccessful attempts to bring her along, Sousuke had left at Gou's encouragement.

Almost ten hours later, here she was in bed, still waiting for her brother to return home to her, and for the opportunity to apologize and congratulate him.

With a huff, she peeked out from under her pillow to glimpse her phone on the bed stand for the hundredth time. Three hours ago, Rin had notified her that he'd be coming home late. No new messages since. This feeling of concern for her brother was new and foreign to Gou. Never before did she have to worry about him returning home on time since he'd always do whatever he wanted back in Australia and Samezuka with Gou none the wiser. So she couldn't help but stare at the endless black of her phone's screen for the next ten to twenty minutes.

….

BZZZT!

She felt like she'd been snapped out of a trance when her phone vibrated against the wood of the desk and the screen lit up to show a new text. From Sousuke.

Got your bro. Can u get the door?

The stairs, thankfully, did not creak as Gou tiptoed her way down. Feet padded silently on the floorboards before she stopped at the door and opened it to reveal a half-conscious Rin held up by Sousuke.

"Hey." Sousuke nodded in greeting. His cheeks were a bit flushed but nothing like Rin's face which was practically the same shade as his hair. His eyes did a quick once-over of her, taking in the oversized navy shirt that hung off a shoulder and covered down to almost her knees. In her hurry, she'd forgotten to throw on pants, but she was too focused on her brother to care.

"Is he—is he drunk?" Gou hissed.

"A little…" Sousuke whispered, indicating for her to help with Rin's other side. She came around and threw Rin's arm over her shoulders, helping Sousuke drag the former Samezuka Captain over to the living room couch. They adjusted Rin's position so that he sat slouched and limp on the sofa.

"A little is a bit of an understatement…" Gou mumbled as they both watched Rin's head droop side to side. His eyes were still open halfway but his gaze was distant as if he was searching for something that was definitely not here. His lips moved to form words Gou couldn't even understand. "He's completely wasted."

"Really? What gave it away?"

"Well, definitely not the fact that he's muttering incoherent nonsense." Gou narrowed her eyes at Sousuke who stiffened. "Help me get his jacket and shoes off."

"Ai was the one who brought the alcohol." Sousuke explained as they shed off Rin's extra clothing, lifting limbs and pushing aside muscles. Just lifting her brother's arm corded with muscle was a work out of its own. "He said it wasn't a proper celebration without a bit of drinking and… I guess we didn't know our limits."

"I don't think Onii-chan even drinks?" Gou said, folding her brother's jacket to place on the coffee table. It was true; Rin never drank because he liked to keep his body and mind clean and clear of anything that would dare hinder his performance. Was it maybe her fault that he drank tonight? Was it in reaction to how she had been treating him these past few days? Gou wasn't sure.

"I think he should stay here for the night." Sousuke suggested, standing up to fan the front of his face. The flush of alcohol, though not nearly as bad as Rin, was still evident on Sousuke's cheeks. "It's too much of a hassle to carry him upstairs to his room."

"Okay." Gou agreed, keeping an eye on Sousuke. She touched his arm, a bit surprised at how hot his skin was. "Hey, are you all right? You don't look so good either."

"Yeah…" Sousuke waved off her concern, though his eyes looked more dazed than ever. "Just gotta sleep it off."

When he started for the door, Gou grabbed his hand to stop him. He looked back at her, then down at their hands, then back at her face. His teal blue eyes squinted in confusion and she bit her lip to keep from laughing at how cute he looked at the moment. "You think I'm just gonna let you go and drive like that? Come on, I know you can make it to Rin's room."

"Y-you sure?" His breathing was labored but he was somehow still standing on two feet. Although it looked like he could drop any moment.

"Well, I'm sure Onii-chan won't mind." Gou tugged on his hand, leading Sousuke to the staircase. She placed his arm with the good shoulder over her own shoulders like she did with Rin. "Here, lean on me or you might fall."

"Thanks, Gou." Sousuke muttered as they slowly began taking one step at a time.

With Sousuke being about six feet in height, Gou wasn't surprised to find him equally heavy. His hand braced against the wall while he leaned on her for support but it still felt like she was carrying a whole mountain on her back. It seemed he was more drunk than he let on too, because he'd stumble here and there. The swaying was what scared Gou. One sway too far to the side and they'd wake the whole house by crashing down the stairs.

"Shit." Sousuke swore under his breath. "Why so many stairs?"

"There's only ten." Gou panted against his weight. "Careful, that spot creaks."

"Fucking feels like a thousand." He said breathlessly. When Gou shushed him, he smirked and said quietly, "Sorry. I'll watch the language."

Gou rolled her eyes but she couldn't hold back a smile. "You're so drunk."

It was a relief when they finally reached the top and Gou carefully watched Sousuke wobble his way to Rin's room. At first, he accidentally entered hers, and she had to hold back a fit of giggles when he came back out looking more red than ever at the mistake. Not that it was his fault; it'd been years since he last visited Rin's room.

"Kind of looks the same as ever." Sousuke noted when he took in Rin's room. Posters of Olympic athletes hung on pastel blue walls, on the desk sat an open notebook flipped to a page of the team's times, a sports jacket slung over the back of his chair, and a duffel bag was prepared in the corner for swim practice. Not messy, but Gou personally thought Rin hadn't vacuumed his room in too long. She'd remind him the next time.

"You can borrow some of his clothes." She opened the chest drawer by the closet to sift through folded clothing. She paused. "Err, do you want underwear?"

"Ah.. no, 's fine."

She gave him a set of grey sweatpants that would reach just above his ankles, and a white tank top with a little black check mark on the upper right.

"Thanks." Sousuke whispered. He paused and looked awkward for a moment before he turned his back to her and started undressing. Gou shifted uncomfortably on her bare feet. Was she supposed to stay or go now? He hadn't told her to leave. What if he needed something else? Then again, it was a bit inappropriate to watch a man undress in a room alone with him. At the same time, Gou felt that it wasn't much different from the guys on the swim team wearing nothing but tight polyester on their—oh yes, those triceps looked absolutely gorgeous!

She blinked out of her stupor when Sousuke began unbuckling his belt. There was a small click before his pants drooped around his narrow hips and he began stepping out of them.

"Umm, d-do you need anything else?" Gou managed to say, tilting her head aside to admire how firm his glutes looked under his black boxers. For some reason, she felt she needed to look away for this part. So, out of courtesy, she spun around to face the door.

"Uh, no, I don't think so." Sousuke cleared his throat after quickly slipping on the sweats and shirt. "I'm good now."

For the most part, they fit him fine. Sousuke had nearly the exact same physique as Rin, if not for a few more inches of height. Gou nodded her approval as Sousuke sat on the bed.

"Well," She reached for the doorknob. "If you need anything else, just text me. I'm right next door. I'm just gonna go down and check on my brother."

"Sounds good." He nodded, climbing into the covers already to sleep. "And Gou?"

"Yes?" She looked back at him.

"Thanks again." Sousuke smiled softly in appreciation. The dim lighting of the room made his teal blue eyes seem brighter.

Gou returned the smile. "Goodnight, Sousuke-kun."

"Night, Gou."

She slowly closed the door before heading back downstairs. Instead of going directly to the living room, however, she made way for the kitchen to fill a glass of water. When Gou did get to the living room, she found her brother more awake than she had last left him. He was grunting, struggling to strip off the shirt that clung to his sweaty torso.

"Onii-chan, here, let me." Gou set the glass of water on the coffee table beside his jacket. Rin mumbled something but calmed down slightly when Gou touched his shoulders and slowly guided him out of his offending top. He seemed to breathe more easily, slouching back against the sofa.

A little drool trickled from the corner of his mouth and Gou decided he needed to be cleaned up a bit so that he could sleep more comfortably. After grabbing a hand towel from the closet and soaking it in warm water, she began to gently pat the sweat from Rin's upper body.

"You're ok." Gou whispered, brushing his bangs aside. He watched her through half-lidded eyes as she gingerly pressed the towel onto his neck, down his toned chest, and over firm shoulders. She was careful with his stomach because she knew Rin was secretly ticklish there. He seemed to shudder slightly when she began wiping the skin of his waist. "Shhh, you're ok, Onii-chan. It's me, Gou."

"Gou." He said in a hoarse voice. His hand reached up to brush a bit of hair behind her ear, fingers grazing the edge of her jaw before returning to his side.

"I won't tell Okaa-san as long as you promise not to get this wasted." Gou started to mop the sweat off her brother's face. He was still staring quietly at her, but she was a bit surprised when Rin grasped her wrist and slowly kissed the inside of it.

"You're beautiful." He slurred. "You my girlfriend?"

"I'm your sister." Gou said only that. She honestly wasn't sure how to answer that question. Grabbing the cup behind her, she tilted it up to Rin's lips. "Here, drink some water so you won't wake up with such a bad hangover later."

He sipped at the cup, his face contorting into disgust for a second, but he continued drinking, his eyes never straying from her. When the water was ¾ of the way gone, she pulled it back to wipe at the drool and water dripping down his chin.

"I love you." Rin blurted out a bit too loudly. Water he had forgotten to swallow poured down his chin and soaked part of his top.

"Onii-chan!" Gou hissed, clamping a hand over his mouth while looking at the staircase to see if he had woken up their mom. "You've got to keep your voice down!"

"Gou, I love you so much." Rin knocked her hand aside to speak. In doing so, the cup she still held fell on her, spilling the rest of the water down the front of her shirt.

"Thanks, I love you too, Onii-chan..." Gou said distastefully, picking at the sopping wet front of her shirt. On the bright side, it wasn't so hot anymore? She stood up and Rin's eyes followed her like a sad, rejected puppy. "I think you're fine now. I'm gonna go and change. Get some rest."

She didn't expect Rin to wrap his arms around her waist and pull her down onto the sofa. He loomed over her, his body eclipsing hers and sinewy arms caging her in.

"You dun understand.. I love you so much it hurts." His garnet eyes seemed dazed one moment and sharp the next. It was how he slurred and spoke slowly that told Gou her brother was still completely wasted. "When I swam, I swam like I was swimming to you. Needed your air." His eyes fell to her lips which had parted in surprise.

"Onii-chan, let's talk when you're sober." Gou suggested, touching the arm that caged her against the sofa.

"Gou," A certain seriousness glimmered in Rin's eyes despite the alcohol still affecting him. His mouth gaped open for a few seconds like he was mentally struggling to put the thought into a coherent sentence. "I want to put a baby in you."

Upstairs, Sousuke laid in bed with his eyes wide open, staring at the plain ceiling above him. His head throbbed a bit too much for him to sleep at the moment, but Sousuke didn't want to bother Gou any further.

He sighed, closing his eyes in an attempt to sleep. Then he frowned, turning his head aside to sniff Rin's pillow. It smelled mostly of mint, a bit of chlorine, and… strawberries? How strange… The strawberry scent reminded Sousuke of Gou, for some reason. But…?

Hm, maybe Rin had run out of shampoo and borrowed his sister's?

Gou's mouth dropped open. Okay, she was definitely not expecting that.

"I want to put a baby in you, right now." Rin growled under a thick slur. He swayed above her slightly and Gou took that opportunity to slip her body upwards, grabbing the armrest above her to pull herself over it.

"Onii-chan, I think you need to go sleep now." Gou tried to chuckle off the seriousness she felt from her brother. Just as she was about to climb over the sofa armrest to escape, a pair of strong hands grabbed her hips.

"We gotta make a baby first." Rin said from behind her. He leaned forward, the couch dipping under his weight, and Gou gasped upon feeling Rin nuzzle his face between her butt cheeks. "Baby making time…"

"Th-that's not where you make a baby!" Gou practically squeaked out, careful not to raise her voice. But Rin didn't listen to her. She felt him lift the hem of her large night shirt over her back so that her panties were exposed to him.

"You've got a really shexy ashhh." She heard him say and she bit back a yelp upon feeling Rin slap her bottom firmly, her rear jiggling from the force of the hit. Gou's cheeks burned hot at the sudden aggression, even as Rin went on to gently caress his hands all over the plump curves of her butt. He chuckled, deep and slow, still out of it. "Mm, cute like a p-peach."

Gou's knuckles whitened, tightening her grip on the armrest upon feeling a thick tongue lick languidly up the curve of her left butt cheek. A chilly coolness followed the trail of saliva he'd left behind on her flesh.

"Onii-chan, that's enough." Gou whispered shakily. She reached a hand back to stop him from fondling her any further back there but she jolted upon feeling his lips on her left butt cheek.

"You're soft here too…" Rin continued giving hot, wet kisses all over both sides of her ass, alternating between each cheek. If he pulled those panties down any further, then Rin would have full, easy access to what he truly he wanted.

"Onii-chan, stop, please! We'll get caught!" Gou couldn't help but shiver under the sensation of Rin kissing her back there. She hadn't been aware of how sensitive she could be at those spots. Did it have to do with how he had slapped her first? "Uhh! P-please…"

It wasn't good that Gou could feel herself getting wet from his treatment. Not good at all. If Rin saw her panties getting wet, or worse, smell her arousal then it would only encourage him more. This was bad. Gou never expected the situation to evolve into.. something like this!

"We—we have to stop…" Gou grabbed onto the armrest again and struggled to pull herself over it for escape. She immediately gave up though upon feeling the same hands grip her hips again and twist her around so that she was back to laying underneath Rin.

"I'm gonna put a baby in you now, Gou." Rin's eyes no longer seemed dazed but she could still smell the burn of alcohol on his tongue.

"I-I don't think now is the best time?" She tried for a lighthearted smile but it fell when she caught sight of the tent in her brother's pants. "Y-y-you're not thinking straight. Okaa-san can catch us any moment. We—she—she can't see her children like this..."

Her brother paused with a hand stuck down his pants. He stared blankly at the staircase for a long moment before proceeding to casually pull out his erection. "I dun see Okaa-chan. Sho she can't see us."

Ohhhh no. Her panties were definitely wet now. How Rin could seduce Gou in a completely drunken state both amused and terrified her. This was it. They were going to be caught—she was absolutely sure of it. And if their mom didn't catch them like this then surely Sousuke would. What would he think of his two childhood friends, she wondered as she squeezed her eyes shut in anticipation of her panty removal. What would he say if he saw us, a brother and a sister, having sex on the living room couch? What would he—

"Nghh…" Gou opened her eyes, expecting Rin to be spreading her legs to penetrate her. She didn't expect him to be masturbating unabashedly.

His gaze on her remained hooded and lustful while he quickly pumped himself with his hand. She could hear the wet sounds of his precum spreading all over his cock as he rubbed himself furiously.

Shlik! Shlik! Shlik! Shlik!

Gou had to admit: Rin looked deliciously sexy, half naked and masturbating. His taut body shined with sweat, lips slightly parted open for breath, muscles flexed everywhere as Rin pumped himself to orgasm.

"Haah! Haah! It's.. coming out!" Rin grunted, his cock still aimed directly at her. "It's coming out!"

Through gritted teeth, he quickly reached for the hem of Gou's shirt and pushed it up to expose her flat stomach. Then, before she could question the action, Rin groaned and spilled himself all over her stomach. Milky white ribbons flew forth from the slit of his engorged penis to decorate her stomach like icing on a cake. With her mouth shaped into a small o, Gou watched as her brother continued cumming on her, his spurts becoming more inconsistent and smaller each time. The heat of his semen felt like a burn everywhere it landed on her. Gou was still in shock even as the fluid cooled down and Rin leaned forward to study the mess he created, as if it was an art project instead.

"I planted the seed." He said breathlessly, cheeks flushed red more than ever now but he looked so triumphant. "Gonna grow into a baby…"

"I… Onii… Th-thats now how it works." Gou whispered after she finally processed what had just happened. For the first time ever, she just witnessed her brother masturbate and then climax all over her body. "B-babies come after s-s-sex…"

There was something strangely arousing to see someone—a person you'd known all your life and grew up with—intimately express themselves while in their most vulnerable, sexual state. It was one thing to have sex with her older brother, but it was a different thing to watch him masturbate like that. It was kind of like being let in on a secret that had been withheld from you for too long. Gou was pleased to see another side of her brother that nobody had seen before until now.

"Babies.. after sex? No, I… " Rin squinted at her like she had just told him bananas are actually vegetables. He glanced at her stomach, then to her face, then to her stomach, and back to her face. "But I planted my seed?"

"N-no, Onii-chan, it—you, um, didn't plant your seed right…" Gou reached for the napkins sitting on the coffee table. Rin watched her as she mopped her stomach clean of his cum. "To—to make babies… you.. you put your thing.. you put your thing in me… a-and when you shoot your stuff inside… your, um, your seed fertilizes one of my eggs…"

Why on earth was she giving her brother a lesson on sexual reproduction in the middle of the night with him drunk?!

"What thing?" Drunk Rin didn't get the hint, or he wasn't following her at all.

"Your…" She glimpsed down at his half-hard cock, still shining with his own juices. "Your penis…"

"Ohhhh. Huh, forgot dat." Rin looked down to where her eyes had just been. He licked his lips. "Y'know, I had a dweam lash night about the race. Gish me pwize?"

Gou frowned. "A medal?"

"Nooooo!" Rin drawled out a bit loudly and Gou shushed him in a panic. He grinned drunkenly at her, shark teeth glinting in the thin light of the moon. "I got you ash my pwize. You was there… waiting for me at the end, and then…"

"And then..?"

"Nn then, mmmn," Rin leaned in to whisper in her ear, "you spreaded your legsss wide open for meh and… and we fucked rrrreally hard in da pool."

Gou went beet red in the face at the promiscuous idea. "O-Oh!"

"Probibably ca-caused a, uhh, tsunami thingy from how hard we wash going—going at it. Your criesh were echoing sho loudly—"

"O-okay, that's nice!" She interrupted him from finishing. There was so much heat between them, making her feel uncomfortable and sweaty in several ways. Talk about a wet dream!

"Sho, let ushhh have shex!" A bit of Rin's drool dripped down onto her collar bone, slowly oozing its way down her cleavage.

"We can't!" Gou's face was unbearably hot and she tilted her head back to check the staircase.

"Why… why not?" Rin asked. His handsome face split into a wolfish but lopsided grin. "I don't bite."

He did, in fact, bite. A lot. His teeth marks all over her breasts and stomach were now faint but still there as scars. It was difficult to see but noticeable if she knew exactly where to look—which Gou did. It was a miracle how she'd been able to withstand the pain of being bitten so hard but her brother had probably done it in the heat of the moment when she could register nothing but blinding pleasure.

"You virgin?"

"No!" She answered too quickly.

Hot fury glinted in her brother's eyes as he narrowed his gaze down at her. She could practically see how sharp his teeth were when he snarled, "What. Who did it? Who took took your virgin—virgininity, Kou?"

"You did, Onii-chan!" Gou frantically indicated for him to keep his voice down. She cupped his face and shushed him to calm Rin down.

"I took your virginity?" Rin blinked. Suddenly, his brows furrowed in worry. "So… what happened to your cherry? Wh-where did the thingy go?!"

"Hush, Onii-chan, please!"

"I… I wanteded that cherwy." He hiccuped sadly.

How in the world was he not knocked out yet?!

"My… cherry is right here." Gou sighed, and pointed to the space just above her panties. "Or was. You popped it, remember?"

This was definitely the strangest metaphorical conversation she'd ever had.

"I popped your cherwy thingy?" The worry on Rin's face deepened and he placed a trembling hand on her abdomen. She could feel the stickiness of his semen rub from his hand onto her skin but she honestly didn't mind. "Can't remember… I'm sho shorry… I-I didn't mean to bweak your cherry. I know it tasted shweet as fuckles but can—can we get it back?"

Oh, this was getting too far ridiculous now. Gou took his hand off her abdomen and wiped both of them clean with a tissue. "It's all right, Onii-chan. It means you broke my hymen and... I wanted you to."

"But wh-why?" He struggled to speak coherently and his poor attempt to warmed her heart. "If.. If Okaa-chan finds out, I… I'mma be shoooo gwounded. But… your cherwy tasted real good, heh heh."

She couldn't help but smile fondly at her brother. Caressing his warm cheek with the back of her hand, Gou murmured to him, "Because I love you."

He seemed to relax completely at that. The alcoholic daze in his smouldering eyes still remained but Rin seemed to understand her words entirely.

"Dat's weird. I love you too." Rin leaned down and clumsily kissed Gou on the lips. She tasted the bitterness of the alcohol on his tongue and she swore she felt a slight buzz rush through her head and tingle throughout her body.

"But… I feels like… my love for ya… ish inaproperate." He spoke in between deep kisses. It was hard to focus on what Rin was saying when he was kissing her like this. "Like I… I shouldn' be… touchin' you wike dis."

"Just love me… the way I.. love you… Like this." Gou brought her lips to Rin's again, letting their tongues meet. She sipped the remnants of strong alcohol from him, getting a taste of something she'd never had. Something only her brother could ever give to her.

Moaning quietly into his mouth, Gou appreciated the feel of his thumbs caressing the sensitive skin of her waist in small circles. She loved it when he did that.

Logic told her to stop and not risk getting caught. But she was too caught up in her love and desire for her brother to bother pushing him away. Too many years they'd been unable to touch each other. Being able to kiss Rin now felt like a sip of crisp, cool water in the middle of a desert for Gou. She knew they looked absolutely scandalous and sinful like this on the couch. She knew it was too risky for them. But…

More.

Gou's heart was filled with love for her brother, but she wanted her body to be filled by him just as much. Filled to the brim until it was too much for her to take in, and then let that hungry love be stoked with every sharp and powerful thrust of her brother's hips.

More, she thought, and Gou accidentally let out a quiet moan.

To her surprise, it was Rin who stopped the kisses. When he released her, a thin line of saliva connected their mouths, stretching out until it fell on her chin. She was quite dizzy when Rin whispered against her lips, "Sho can I put a baby in ya now?"

Gou wanted to laugh and groan at the same time. Oh hell, it's not like he'll remember any of this when he wakes up, she thought idly. All right, she guessed she'd just have to play along. With her heart still racing from their steamy make out session, Gou rested her hands atop of her exposed stomach. "I'm already pregnant, Onii-chan."

Rin sucked in a shaky breath. His eyes flew to where her hands were and he asked in a small voice, "My child?"

For a moment, Gou felt bad at having to lie like this, but she nodded. "I'm pregnant with your child, Onii-chan."

There was something in her brother's face that made Gou's chest tighten with emotions. His gaze looked so gentle and it reminded her of the first time they had made love. Rough hands trembled around the curve of her waist as he flattened his palms over the vulnerable skin of her belly. There was something about how her brother looked so fragile in that moment that made Gou's eyes burn with unshed tears.

Do you…" She hesitated, "um, do you want me to give birth to it?"

"Dat's my baby in there…" His mind may have been hazy with alcohol but his words this time were clear and not slurred. "Our baby…"

"Even though… you're my big brother, and I'm your little sister…" She spoke to him in such a delicate whisper. "Even though my brother wasn't supposed to impregnate me… still, I carry his child in me. A baby between siblings is impossible, and yet it happened. Would you… would you still love me if—if I gave birth to a forbidden child? A child born of incest?"

"A bwotha shouldn' put a baby in his 'lil sis. But if you got pregnant 'cause of me 'n you wanted it… I think dat be kinda hot… " Rin blinked slowly, seemingly confused. He didn't understand that Gou was talking about him. "But we can't. I-I take care of my sista, not… no babies. But I… I wuv—I love you, Kou."

It didn't answer her hypothetical question but Gou knew it was pointless to press the matter with Rin in this state, though she practically deflated with disappointment. "I love you too, Onii-chan."

"Ish it.. is it wrong if I think it be sexy if I got my own sister pregernant?" Rin asked after Gou quickly wiped a bit more saliva from his lips. "I feel like.. that's a bad thing? Sorry… can't think well. What da fuck did I dwink?"

"... No, Onii-chan." Gou said quietly, leaning up to kiss the tip of his nose. Pity tightened in her chest at how lost and confused her brother was. She'd never seen him like this before, so she made a mental note to not let him touch hard liquor unless he could handle it. Or at least drink it in moderation. "I don't think it's a bad thing… Not if the siblings truly love each other like that…."

"Hmm… Oh yeah, the baby! Heh heh, hi there, baby…" Rin leaned forward and nuzzled his face to the softness of Gou's belly. She tried not to giggle when his nose grazed her bellybutton. "Hey, you cozy in there? Listen, I know you c-can't hear me but… just wanted to shay I alweady love you sho much. Momma and Dadda love you more than you can im-imagine. Don't forget that… Fucking loves you lots—Oh shit, shorry, I shouldn't cursh in front of babies. Shhh, you didn't hear nuthin.."

Gou swallowed down the thickness in her throat and she swiped a tear away before Rin could see. She took in a deep breath before touching Rin's arm braced beside her. "Okay, the baby is tired now, Onii-chan. Sleepy time!"

Rin finally pulled back enough to give Gou enough space to get off the couch. She adjusted her shirt a bit, hesitated briefly, then awkwardly reached to tug Rin's pants back over his partially hard cock.

"I'm—I'm gonna go now." She cleared her throat but, as Gou turned around, she felt Rin grasp her wrist.

"Can I say goodnight to our baby?" Rin smiled expectantly. His cheeks were still red but Gou could no longer tell if it was from the heat, the alcohol, or his arousal. Probably all three. Not the best combination.

"Um, okay." Gou faced him again. He gestured to her nightshirt and she lifted the front up high enough to expose her belly to Rin.

"Hmm, so soft…" He began nuzzling his face on her tummy again.

"Onii-chan…"

"Right. Good night, baby, sweet dreams." Rin pressed a nice and slow kiss onto Gou's belly that made her feel warm and tingly. Her lips curled up in affection as she watched her brother.

Then he pressed another kiss, then another one, and another. Soon, his kisses were becoming quite steamy, leaving her skin feeling hot and wet everywhere his lips touched.

"W-wait…" Gou bit her bottom lip. The hands hugging her hips were now dragging the sides of her panties down so leisurely that she almost didn't notice until they were just below her butt. His kisses immediately began traveling south of her body, following the descent of her panties.

Gou let go of her shirt and it fell over her brother's head. It didn't stop him though, so she grabbed the front of her panties to keep herself from becoming completely exposed to him. "Onii-chan, stop!"

How sly of him! No way he was getting in her panties this time!

"What's wrong?" Rin's voice was muffled against her belly. The sharp sound of his wanton kisses echoed beneath her shirt and to Gou it sounded like it was resonating throughout the whole house for everyone to hear.

She winced at the way his breath tickled her, reminding her of how vulnerable her body was to Rin right now. If his mouth got her down there, she'd likely collapse into his arms and let him finish the deed. What was worse was that, while she could hold onto her panties, her breasts were left open to attack. All he had to do was move up and—OH NO, HE'S MOVING UP.

"You're wet here too…" She felt Rin lick too closely to the underside of her breast, teeth grazing her ribs.

"Onii-chan, th-that's enough." Gou managed to say firmly, stepping back so that her shirt slipped off Rin and fell properly back into place."That's the water from when you spilled the cup on me… Onii—Onii-chan?"

Without saying anything, Rin grabbed her hand and tugged her onto his lap. She fell forward, hands flying to his toned shoulders to steady herself. Gou was about ready to berate her brother until she froze at the feeling of something hot and hard poking the inside of her thigh. "Onii-chan, please! Don't—hyah!"

Clamping a hand over her mouth to stifle her cries, Gou peered down to find Rin gripping her breasts tightly with both hands. She could see the flesh of each breast plump in between his fingers as he squeezed them repeatedly.

"They're wet…." Rin noted, his alcoholic breath fanned the side of her neck hotly. "Is this breast milk?"

"I.. I don't have breast milk…" Gou tightened a fist onto her brother's shoulder. The thin material of her shirt did nothing to protect her from Rin's treatment. If she had a bra on then maybe she wouldn't have felt it so much. Instead, much to her embarrassment, Gou's nipples were already pointing through her shirt. "Onii-chan, please, we'll get caught…"

Ohhh yes, she couldn't help but think to herself.

"Can I taste your breast milk?" Rin asked in a whisper and before Gou could say anything, he squeezed a breast up and placed his mouth directly over her tip.

"That—that's weird, isn't it?—Hnn!" She moaned sharply into the cage of her hand, eyes shut and tearful as Rin's hot mouth bore down on her breast. Instinctively, she angled her body to give her brother better access while she sat on his lap. His tongue seeped through her already wet shirt, painting her breasts with his saliva. He shifted his mouth around, gingerly nibbling and sucking here and there. Sharp teeth scraped deliciously around the curves of her breast and Gou had to bite onto Rin's shoulder to muffle her pleasured sobs.

He was being a bit too rough on her, although Rin had always been a beast during sex. She knew her brother was an aggressive partner from the moment they had shared their very first kiss. And Gou accepted that. She didn't mind it all. The way her brother would just lift her onto a surface and spread her legs open, his hungry eyes eagerly feasting on the pink flesh of her pussy. The way his sharp teeth grazed a rosy tip too hard that it left her breathless and her skin scarred forever. Or when his tongue scraped harshly at the walls of her sex. His kisses were often bruising and powerful, enough to leave marks on her body that lasted over a week.

And the way Rin slid into her with every sharp snap of his hips, rattling Gou to the very core of her soul until she could do nothing but hold on desperately to her brother's shoulders.

And she loved it.

Every look, every touch—every kiss of her slit, nip at her breast, slap of their flesh. Every time he devoured her with his eyes or with his tongue.

Every time Rin murmured 'I love you' into the red crown of her hair whenever he thought his sister was sleeping.

Gou loved how he was so passionate with her and yet so afraid of breaking her. The love Rin poured into her body was so beautiful and exuberant that Gou found herself wanting her brother to break her. To leave an irreparable scar deep within her in body and soul.

If only because she trusted him to put her back together again.

Because as much as he was aggressively passionate in making love to her, Rin was also heartbreakingly gentle. And in the pitch black of the night, when her naked body was pressed up against his and she was on the cusps of sleep, Rin serviced Gou with that gentleness.

A beast he was indeed, but even beasts were not without love.

"Onii-chan!" Gou whimpered out when Rin sucked her tip so painfully hard that there was a small, wet 'pop!' sound when he released her nipple.

Too long.

It'd been too long since they'd had sex. Well, just a little over two weeks, actually—but they'd only recently revealed their feelings for each other and consummated it finally after two decades.

She was in a daze when she felt her body be lowered back onto the couch carefully. Through the dim light of the moon, Gou saw Rin peer down at her, tucking loose hair behind her ears again. Then his hands were on her thighs and he was spreading her legs open. One leg he draped over the back of the couch and her other leg was lowered to the floor.

"The… baby…" Gou panted. That was her first thought. Her second thought was the condoms. They were siblings but they had yet to use proper protection. Except the condoms were in Rin's room. And Sousuke was in Rin's room at the moment. She should have started taking those birth control pills that she got from the Planned Parenthood clinic, but she wasn't sure if Rin and her would ever be able to have sex again. Perhaps she should start taking them after all.

And, suddenly, Gou wanted to laugh. It was almost hilarious to think that the bigger issue at the moment was the lack of condoms and risk of pregnancy when there was an even larger problem at stake. The fact that they were siblings. And that was an issue that would always haunt them with no solution possible.

"I wanna put another baby in you." Rin said in a low, almost seductive whisper. He dragged a hand back through his ruby hair, brushing it out of his flushed face. A drop of sweat rolled down between firm pecs, then past the cracks of his abs. His whole body gleamed with sweat, making his muscles shine ridiculously beautiful under the waning moonlight. Her brother reminded Gou of those Greek sculptures of naked men she'd once seen at a museum. All cold marble and hard muscles. But Rin was all passion, lust, and sweat dripping down the cracks of solid abs that rippled with every movement. His broad and muscular shoulders eclipsed her body as he loomed above her. And when she touched his bare, hard flesh, he was not cold like marble, but feverishly hot.

Rin was the epitome of a sex god and Gou, his sister, was the recipient of his services.

She blushed hard. "H-How many babies do you want?"

"I wanna—wanna make a shit ton of babies wif you, Kou…" Her brother answered with such determination and confidence despite tripping over his words.

It doesn't work like that, Gou wanted to say, but she doubted he would even listen. Her mind was in a frenzy. Did she tell him the truth and admit she was not pregnant? Would that stop him, or encourage him?

It didn't matter anymore because she could feel Rin's hot breath against the thin cotton of her panties, lighting up her core, making her body quiver with wanton need and anticipation.

It'd been so long since he touched her like this… maybe… maybe she could let it happen, just for this night. She could just take another Plan B pill the next morning. They'd be quiet tonight too—she would make sure of it somehow. The couch wouldn't creak while they had sex, and Gou would ensure not a single drop of their body fluids would stain the cushions. Besides, everyone else was already asleep by now and—something rumbled by her leg.

She craned her neck up and blinked at the sight of her brother passed out and snoring peacefully with not a care in the world. His face rested against her inner thigh, using her leg as a pillow.

"Onii… chan?" She poked his cheek carefully. Then she did it again but firmly.

A fresh trail of saliva was already spilling over his lips and onto her bare thigh.

"Wha…" Gou rested her head back and stared up at the ceiling in shock. Hadn't they just been arguing about sex and making babies only a minute ago?

Oh, brother! Climbing off the sofa, she mumbled to herself, "The only baby here is this big baby on the couch…."

After fixing her clothes, she huffed and grabbed Rin's limbs to adjust his body into a comfortable sleeping position. With the way he was knocked out, Gou was tempted to smack him in the face with a pillow. Instead, she took a deep breath to compose herself. Checking one last time that her brother was okay for the rest of the night, she decided to return upstairs and tuck in for the night. She definitely needed the rest. Most of all, she really needed to change out of her soaking wet panties and shirt.

"And I just did laundry yesterday." Gou rolled her eyes, flicking the kitchen light off on her way upstairs.

A/N: Shit is going to hit the fan real soon. But before that, be ready to be served some delicious, freshly squeezed lemons starting next week!
