Chapter 11: A Side of Strawberry Kisses


Today.

Today was a beautiful day.

The weather was clear with little puffs of clouds splayed across the blue expanse. Birds chirped their good mornings into the balmy heat of summer. The cicadas competed with their own rhythmic song but Gou was too busy contemplating the problem before her to bother listening to Mother Nature's calls.

Two articles of clothing were laid at the edge of her bed, side by side for comparison. On the left was a wine red, two-piece bikini. It was pretty simple with no other design save for the typical strings that she'd tie together to wear. The choice on the right was a more modest approach. It was the white, polka-dotted one piece that Gou had worn the last time she'd gone to the beach for fun.

Which was years ago.

When she was thirteen—or was it fourteen?

"Maybe I can still fit it?" Gou mumbled, tapping a finger against her chin in thought.

A few minutes later, Gou found herself struggling for breath as she fought to pull the one-piece all the way up her body. Goodness, just how much weight had she gained over the years? Her breasts were practically spilling out of the suit. The area around her lower belly was especially tight, stretching the material so much that it couldn't even stretch any further. And the zipper was barely even halfway up!

"The two-piece it is then." She spoke in a tight voice, fighting for breath as she dragged the zipper back down. Her lower belly practically settled back down once the tight pressure of the suit was off. Well, if Gou ever needed to wear a corset, she could at least improvise with this.

Tossing the old swimsuit into the depths of her closet, Gou sighed and turned her attention to the two-piece awaiting her. The wine red color was her taste, at least. Chigusa had bought it for her as a gift last year but Gou could never find a reason to wear it. Or, more like, she was too shy to wear such a sexy piece of clothing. In public too. To show that much skin before the obtrusive gaze of strangers? The thought was unsettling.

Chigusa had told Gou many times of how beautiful she was. How she could easily find a boyfriend if she so desired. Even Rin had whispered compliments into her ear when she was wearing nothing but her underwear or... nothing at all. At first, she thought he just felt obligated to say those things as her brother. And when he looked at Gou as if she was the most valuable thing in the world, she could believe him. In private, however, was another matter. She would stand there before the mirror, with or without underwear, and scrutinize the tiniest flaws.

My skin is too pale.

Where did I get this scar?

My hips are so wide.

And she'd twist her body around slightly to frown at the stretch marks beneath her butt. So visible and foreign. Not beautiful like the kiss marks Rin would leave on her breasts, or back, or neck.

But with Rin… With her brother, she felt beautiful. The first time they made love, Rin hadn't said a word about the flaws of her body. Perhaps he was too fighting off his feelings of lust for his sister to notice her flaws. But even when he finally gave in and began making love to her, he had only kissed every inch of her body. Including her flaws. As if they were nonexistent to him. And as Gou realized that, she began to tear up.

She missed him.

They were so close together, but it still felt as if miles separated them apart.

Gou turned her eyes to the wall at her right, imagining her brother standing parallel to her just behind the wall.

And it was a stupid wall.

A stupid, stupid, needless wall that separated them.

Just because they were brother and sister.

"Rin! Gou!" Their mom's voice shook Gou from her thoughts. "Hurry up, or we'll hit the traffic!"

Sighing, Gou picked up the two-piece and began slipping it on.

She wasn't sure if it fit… correctly? The top barely covered her breasts. Her nipples were safe but the sides of her breasts were exposed. And then there was the issue with the bottom piece. It only seemed to cover half of either butt cheek. The waistband of the bottom piece fit around her abdomen a bit too tightly for comfort. It was nothing Gou couldn't ignore but she knew that once she took it off later that it would leave an imprint.

Was this really a swimsuit or actually a G-string?!

"Hana-chan…" Gou groaned, studying herself in the mirror. She quickly snapped a photo of herself before sending it to her best friend.

I think the size is too small?

Nope! It's perfect on u!

It barely covers my nipples…

Or my lady bits downstairs

That's the point silly

Hana-chan…

Let me know if u catch any good fish!

Fish?

And watch out for predators

There might be some sharks in the water

( ͡° ͜ʖ ͡°)

It took a second for Gou to understand her friend's sexual innuendos. Once she realised what Chigusa meant, Gou's face reddened and she immediately thought of Rin.

Hana-chan!

"Gou, let's go! Your brother is ready!" Mrs. Matsuoka's voice nearly made Gou drop her phone as she sent her reply.

"I'm coming!" Gou shouted. She sifted through her closet briefly before tugging out a thin jacket. She took out the hangar and then froze. A second passed before Gou scrambled into the bathroom just opposite her room and puked into the toilet.

Blegh.

She'd been feeling nauseous the past week but this was the first time she puked. Ugh, something must have been wrong with that leftover pizza she'd scarfed down last night while waiting for her brother to return from his party.

Gou gripped the edge of the sink for support while vomiting out the last bit of dinner in her stomach. Never mind breakfast. Feeling her head start aching, Gou retrieved some aspirin from the cabinet. Rin seemed to have taken some as well since the bottle only had one pill left now. He probably took one as soon as he awoke on the couch with a pounding headache.

The faucet water was cool and soothing when she cupped her hand under it. She rinsed her mouth and gargled a few times before finally popping that aspirin in. Then she grabbed a mouthwash, swishing some in her mouth for minute.

"Gou!"

"I'm coming!" She shouted back after spitting. She began rubbing her belly absentmindedly, willing the strange nauseated feeling to go away. Flushing the toilet, Gou heard her phone chime back in the bedroom.

Another response from Chigusa.

Nom nom

( ͡° ͜ʖ ͡°)


"What a beautiful day!" Mrs. Matsuoka said aloud as she drove her children to the beach.

It was not a beautiful day.

It was too hot.

Was Rin the only one who thought it was hot?

Because his face felt a bit warmer than usual and his blood seemed to be pounding like crazy inside him.

A two-piece.

Just like the last time when they were barely teenagers and Gou had fallen onto Rin. That was the first time he had gotten a good feel of her quickly developing breasts. And then he'd gotten an erection and ran into the water like a boy just starting puberty. Even now, he could remember just how soft Gou's breasts had felt against his chest all those years ago…

Wait, of course he could remember. He'd practically been groping those same breasts just three weeks ago.

It still didn't explain the two-piece. And damn, could his little sister rock it. Admittedly, Rin was a bit taken aback when Gou had arrived downstairs dressed as she was. Her breasts had jiggled with every step she took and Rin had immediately threw his eyes down out of respect. That, and, well, a brother wasn't supposed to be ogling his own sister. Especially when Mom was sitting right beside him.

But why was she wearing a two-piece?! It defined her figure too well and left little to imagination. And in Rin's case, he didn't need to imagine what those little bits of cloth covered. After all, he already had the honor of seeing everything she had to offer. Still, Rin couldn't help but be upset over the fact that strangers would get to see Gou's body so freely. It was too intimate. And Rin hated the fact that, as her brother, he did not have the chance to speak up.

Yet, if Gou had worn that swimsuit because she liked it, then Rin would respect her choice. And he would respect it by gritting his teeth to keep his mouth shut. At least she was wearing a jacket over her swimsuit. It didn't help much since it was too small to even reach Gou's waist and cover her butt. But, Rin supposed it was better than no jacket.

He was wrong. The jacket made no difference.

It was hard for Rin not to eye the swell of her butt as Gou walked before him to the car. Her hips swayed so tantalizingly and Rin knew his hands would fit against her curves perfectly. If he could just touch her…

He was so thankful he sat in the passenger seat. With Gou in the back, he wasn't as tempted to just turn around and absorb her beauty.

Their mom didn't seem to notice the restrained silence, or maybe she thought it was just the way they were. Anyway, there was no way she would be able to tell. They never were together as a family like this. This was the way things were between them.

And honestly? Rin thought it was a bit pitiful.

"Here we are!" Mrs. Matsuoka announced as she parked the car. At the right, just down a slope of sand, was the beach. The same one they visited every time they had the chance.

Rin was the one who visited most often. He'd train for weeks, running through the thick sand to improve his stamina. Sometimes, Gou would visit with him as hisl timer, but now she visited with the Iwatobi Swim Club. Still, it was an extremely rare event for the whole Matsuoka family to attend the beach together. To go now for fun felt kind of weird since, until now, it'd always been treated as a business spot instead.

"Why don't you kids set up a spot for us and I'll go get some drinks from those kiosks." Mrs. Matsuoka suggested, unlocking the trunk to reveal a stash of floaties, an umbrella, several blankets, and other beach necessities.

Without a word, the two siblings began grabbing the supplies. Rin automatically piled the heaviest items in his arms, leaving his sister to carry the lighter items like the tubes. On one of the last few items, he and Gou reached for the same bag. Rin laid his hand on the bag first and Gou accidentally touched her fingers to his. The two siblings jolted, snatching their hands away as if they'd been reaching for a snake instead.

It was Gou who regained her composure first. She cleared her throat politely before claiming the bag and throwing it over her shoulder.

The both of them then started for the slope that led down to the beach strip. Their flip flops kicked up little sprays of sand as they walked. Rin kept ahead of his sister, but as the slope angle deepened, he turned around and grasped Gou's hand. He heard a sharp intake of breath but Gou accepted his support as he helped her down the hill. Once they made it to the beach, where a crowd of people shrieked with laughter and chatter, Rin reluctantly slipped his hand out of his sister's.

"H-How about over there?" Gou pointed a short distance away to a large enough spot of free land. Quickly, she trekked her way over to claim their spot. Rin followed after her, focusing his eyes on the vibrant color of his sister's hair. Under the sun, her garnet locks looked sort of like streaks of fire. He could pick out the strands of red clashing with the deeper wine of her hair. She wore it down today.

It looked beautiful down.

She looked beautiful.

Then again, she always is.

A soft smile spread on Rin's face as he watched his sister from behind. She led the way through waves of other fellow beach visitors and—

His smile dropped, and a deep frown replaced it as a young man grabbed his sister by the arm. Gou jumped in surprise before meeting the hungry gaze of the stranger who wore a flirtatious smile like a tiger licking its chops. Rin knew that look. That disgusting male gaze that objectified any woman.

Rin's fists tightened in fury, anger clouding his mind at the sight of his sister being preyed upon by some nasty asshole looking for fun. He couldn't even hear the plastic swim tube squeaking pitifully in the restraint of his hand as Rin nearly stomped his way over to Gou.

"Maybe you could help us find that secret spot—"

"Let go of her." Rin came up from behind Gou, dropping the swim tube to wrap his hand tightly around the wrist of the man still holding Gou's arm. "Now."

"What the—Who the fuck are you?" The man frowned at Rin, unappreciative of his catch being interrupted. "This guy your boyfriend?"

"No!" Gou said too quickly. She stumbled over her words for a moment but then she quietly said, "H-He's my… my brother…"

It felt wrong to hear that. To hear his sister tell a stranger that they were siblings when the both of them knew just how deep their love truly went.

"Your brother?!" The man exclaimed. He sized Rin up but it only took a second. Rin was taller by over a foot. Not to mention the enormous difference in muscles. "Oh…"

Rin tightened his grip on the man's wrist until he released Gou with a small yelp.

"Look… bro." The man tried to play it off with another grin that made Rin want to punch him. "I'm just asking a cute girl out. Help a brother out, won't you?"

"She's not interested." Rin said flatly.
"Well, what does the lady say, huh?" The man protested, smiling cheekily at Gou. "C'mon. Leave your lame brother and hang out with me and the guys.. We'll show you a fun time…"

"No, thank you." Gou mumbled, taking a step away from the stranger and closer to Rin who was pleased by this action.

"Don't be that way." The man insisted, ignoring the obvious discomfort Gou expressed.

As soon as he touched Gou's shoulder, Rin threw himself in front of the man and snarled into his face, "Don't. Touch her."

"Woah, man—"

"Don't you fucking touch her, look at her, or even breathe in her direction." Rin stepped forward as the man started to inch back. "If I EVER see you near my sister again, you'll fucking regret it."

When Rin stood up to his full height, displaying his sculpted muscles in a threatening manner, the man's face had paled with fear. With a trembling lip, the man nodded and dashed away from the siblings.

Good riddance, piece of shit.

Without a word, Gou silently gathered the beach supplies Rin had dropped.

"Hey, you okay?" He asked after a beat, watching his sister roll out the blanket onto the sand for them to sit on. She nodded, lips compressed together. Rin wasn't sure whether he should touch her, or would the act be too intimate in the public eye? Ah, damn it! What did brothers normally do?!

"I should have been more firm." Gou said, her face blank but eyes vulnerable. "I.. I should have said 'no' and tell him off but…. But I…."

"It's okay to be scared." Rin spoke softly, and he wondered if she could hear him in such a noisy place. "I'll protect you."

"No, no, it's not okay." Gou roughly dug the umbrella into the sand, propping their cover. She grabbed the bag and started unloading the supplies, nearly smacking them down. "I have to be… There's…. If-If I'm alone…"

"Hope you guys like pop because they only got strawberry soda." Their mom suddenly appeared, juggling three glass soda bottles in her arms. "Ah, listen you two, I just got… Hey, you two okay?"

Rin caught the apologetic expression on their mom's face but it was Gou who eventually asked, "You have to leave, don't you?"

Initially, their mom looked surprised. It wasn't just because Gou was too smart that she recognized that expression on their mom's face. It was because she was already used to it.

"I… I do. I'm so sorry." Mrs. Matsuoka set the drinks down with a sigh, "Work called and I have a shift to take over."

Gou remained under the shade of the umbrella but Rin caught her throat bob. Her face was tight and frozen with disappointment for a brief second before his sister focused on one of the bottles and grabbed a soda. She mumbled, "We just finished setting everything up."

"We'll start packing up then." Rin quickly interjected.

"Oh, no, it's all right!" Mrs. Matsuoka stopped Rin from grabbing the tubes. "You and your sister have deserved this trip for so long. I can't even remember when was the last time we were here together."

Five years old.

Rin had been five years old the last time the whole Matsuoka family had been here at this beach together.

Their father included.

"I'm sorry." Rin watched their mom fiddle her hands in distress. "I really wanted to spend the day with my children. I'll make it up to you both next time, okay?"

Without a doubt, Rin knew that 'next time' would be in a very long time.

"It's all right, Okaa-san." He replied. "I'll look after Gou."

"Okay.. Well, my taxi is already here." Mrs. Matsuoka took the car keys from her purse to hand over to Rin. The keys plopped onto his hand, not even warm from the outside yet. "You two stay and enjoy! Make sure to be home before the sun sets. There's money in the glovebox for dinner. Don't wait up for me, okay?"

With a final wave, Mrs. Matsuoka left. Her footprints were the only proof that she'd ever been with her children on the beach.

"Well, so much for a family day." Rin said, plopping himself down beside his sister.

She sat up, staring at the ocean with her chin resting atop of her knees. Her arms remained wrapped tightly around her legs, as if she was holding her whole body together.

Rin noticed one of the strawberry soda pops being held loosely in her fingers, resting against her hip. He let a full minute of silence pass before asking, "Aren't you gonna try it?"

Gou mumbled something in response.

"What?"

She mumbled again and Rin slowly slid his eyes up to her face. It was hard to see Gou's expression since her hair acted as a curtain of obscurity. Then, a cheek glinting with a trail of tears caught Rin's sharp eye and he sat up attentively. "Gou?"

"Hm."

As if to acknowledge him, Gou twist the cap open and took a small sip from the soda bottle. She closed it right after and dropped the bottle from her hand, letting it land with a sad thump onto the blanketed sand.

Suddenly, there was a sniffle.

"Gou." Rin leaned towards his sister, gently touching her shoulder in worry. "Gou, what's wrong? Are you in pain? Talk to me..."

"Please," She spoke in a hoarse voice, turning away from her brother, "don't look at me."

"Let me see you." Rin lowered his voice so it was just above a whisper. He gingerly tucked her hair back and nudged his sister's chin so he could see her face. She finally met his gaze just as another wave of tears spilled down rosy cheeks. With a soft swipe of his thumb, he brushed the tears away. "Tell me what's wrong."

"Nothing's wrong." Gou answered, trying for a smile but it faltered.

"Then why are you crying?" Rin asked, continuing to wipe the tears that streaked down her cheek. It felt so weird being intimate with his sister like this in public. Weird, but right. A feeling he had yet to get used to.

"Because," Gou's voice trembled, "I was wondering what it's like to have a family."

The comment caught Rin by surprise and he was speechless for too long of a moment. "What do you mean?"

"I mean, how is it that I have a father but I don't even know what he sounds like?" This was the first time Rin ever heard his sister sound so bitter and… heartbroken. She was heartbroken, and hearing her like that hurt Rin more than anything. "How is it that I have a mother who never has the time to ask me how my day was? A mother who—who can't hold a conversation with me for more than a few minutes? And a brother who was halfway across the world for most of my life and—"

With the back of her hand, she roughly wiped at her cheeks. The tears continued tracing down, dripping from the soft edge of her jaw.

A soft sob escaped Gou's trembling lips. "You know, it was only recently that I realized… I don't know what a normal family is."

"No family is normal, Gou." Rin murmured to her. "I'm sure, behind those closed doors, every family is dysfunctional—"

"But that's my point!" She finally turned to look at him, eyes bright with tears and frustration. "We're not even dysfunctional—we're just… This? Us? It's not normal. It's like we're just a group of people living together but… never mind. You wouldn't understand."

Those words cut into Rin and he couldn't help but blink at the pain he felt in his chest. Still, it was the truth. He knew what his sister meant. He took a breath and said, "Then help me understand."

"Onii-chan, I hope when you leave me one day," She whispered, slowly reaching up to cup his cheek, "that you never have to know what loneliness is."

"What are you talking about?" Frowning, Rin grasped the hand holding his face, resisting the urge to lay a comforting kiss to her palm. But he couldn't. Not in public. "You have me… Gou, you'll always have me. Your family is right here."

He didn't like what Gou was saying. He didn't like how much she sounded so right. Digging out truths that they'd ignored for years, burying their heads in the sand instead. It was one thing to know the truth, but it was another thing to acknowledge it.

Damn, and today was supposed to be a beautiful day.

"You're my family, but not in the way I want." Gou's eyes flickered across Rin's face, desperately trying to convey what emotions she couldn't speak verbally. "I can't have you the way I want to. I know that, when the time comes, you'll leave me."

"Why.. why are you saying that? I'll never leave you! l—" Rin paused and quickly looked around before he leaned in to his sister and whispered harshly, "I love you, damn it!"

He wasn't used to making such a confession aloud, even to Gou, but he felt it needed to be said.

"Stop it!" Gou pressed the heels of her palms to her eyes in an attempt to hold back any more tears. "You can't say that!"

No. No, fuck this. Fuck everyone else.

Rin grabbed his sister's wrists away from her face and he dove forward to slam his lips against hers. He didn't care if anyone saw them. In that moment, Rin wanted nothing more than to touch his sister. The fear of the public eye was nothing more than a fading thought as he felt Gou's soft lips caress his mouth. Mindful of his sharp teeth, Rin nipped at her bottom lip, coaxing Gou so she'd welcome him in.

She instinctively began to respond to him, and then Gou abruptly shoved him away, shouting for him to stop. She'd pushed Rin hard enough for him to land on his back. Blinking up at the clouds, Rin was too shocked from his sister's actions that it took him a second to realize that the people around them were looking their way.

He was about ready to glare at them when Gou stood up. Her face was paler than usual, eyes glistening with both tears and fear. Clasping her hands to her chest, Gou's whole body seemed to quiver as she mumbled, "I.. I'm sorry, I… I'm—I'm gonna go take a walk…"

Before Rin could respond, Gou was already walking away from him. Sitting up, he watched his sister quickly make her way down to the foamy edge of the sea. Away from him. Once again, Rin felt like there was a chasm separating him and Gou. At the bottom of that chasm was a dark ocean of water. Gou couldn't swim her way across. If he could, Rin would cross that chasm for her, if only the threat of drowning in that dark water didn't threaten him.

That's how it felt. Both willing to cross for the other but neither were able to.

He released an exhausted sigh. At least he didn't have to worry about her drowning, knowing that Gou would never actually enter the water for a swim.

Was it something I said? Or.. did? Was it the kiss? Rin knew it was a risky idea to do something like that in public but… Emotions were a complicated matter. And Rin was never one to verbally express himself. Most of the time, he conveyed his feelings through actions instead of words. Damn it, he had no idea how to handle this kind of situation. Gou was right; their relationship as brother and sister was not normal and that made things tricky. This wasn't just an issue Rin could consult his teammates with, or anyone for that matter.

But he wanted to help his sister. Comfort her. If only he knew how. Approaching her as a brother would only sadden Gou. Yet, approaching her as a lover would scare her too. Either way, there was no way to properly bridge that distance between them. Not while the two of them wore the label of brother and sister.

I was wondering what it's like to have a family.

Why had she said that all of a sudden? This definitely wasn't the first time their mom had to bail out on a family trip for work. There was no question that Mrs. Matsuoka was a workaholic. Admittedly, Rin always felt it was his fault for that. At first, their mom had begun putting in more hours as a way to cope with their father's sudden death. Rin had been too young to recognize the growing distance between them and their mom, but it was obvious now. Over the years, as Rin became more involved in swimming, Mrs. Matsuoka used that as an excuse to work longer and harder.

The first excuse was to pay for the bills now that there was only one breadwinner in the household.

The second excuse was to pay off the expenses for Rin's swimming. Equipment was expensive and swimmers ate five times more than the average growing boy.

The third excuse was to be able to afford sending Rin off to Australia.

In the end, all three excuses were tied to Rin. Money, money, and more money—all for his sake. That was the guilt he felt every time Rin laid eyes on his sister, or watched their mom leave for work. He'd never said it aloud, but deep down he knew he was the reason for Gou's loneliness.

And so, if his sister ever asked him to stay with her—even if it meant forever—then Rin would do so. For her.

He couldn't bear to do it. Leave her alone again. Even if they weren't in a romantic relationship now, as her brother, Rin would never dare leave her again. If he did, he wasn't sure when would be the next time he could see her.

Gou kicked at the receding tide, spraying up some water and she coughed when a bit of the saltwater got in her face. Chuckling slightly, Rin observed his sister wander towards the side of the beach. The side of a large cliff blocked people from progressing any further and visitors treated it as one end of the beach. The cliff was too high for the side to be scaled. There was, however, a pebbled trail from the back that curved around for half a mile, leading to the cliff's crest. It was there that a tall pole staked the top, attracting tourists for pictures. Couples liked to leave stickers on the pole and friends climbed it for the photos.

Maybe once Gou came back from her walk, Rin could take her there to that spot. He'd only been to the cliff top once but Gou had never seen it. Hopefully, the breathtaking view would make her feel better.

Just as Rin decided on the plan, a volleyball smacked into the side of his head.

"Ouch…" He grasped his head with one hand and grabbed the rogue ball with the other.

"Sorry about that!" A sugar sweet voice called out to him and Rin turned around only to have his whole view filled with cleavage. A woman in blonde pigtails was bent over beside him. Rin's eyes trailed up to glossy lips to meet a pair of concerned, caramel eyes.

"Uh, it's okay." Rin blinked, standing up to hand the ball to her. She was just a head shorter than Rin, a couple inches taller than Gou, but she looked about his sister's age.

"Are you sure? That looked pretty painful…" The woman tucked the ball under an arm and she reached up to touch the side of Rin's face. "Here, let me see."

"I'm all right, really." Rin politely moved the woman's hand away. She seemed nice, but he didn't like strangers touching him so casually.

"My—my idiot friend hit the ball too hard." She stammered, eyes drifting down Rin's face to the crack of his firm six-pack. "I'm.. I'm.. Um…"

"Um?" Rin tried not to let his impatience get to him.

"Um…" She caught herself checking his body out too obviously and forced her caramel eyes back to his face. "Oh, I'm Ami!"

"Ami." Rin shook her hand out of courtesy. "Well, tell your friend that she's got a good arm."

He made to turn and sit back down, to signify the end of conversation but the girl said, "Wait! Um, would—I mean, what's your name?"

Ah, man… Honestly, Rin didn't like giving his name out to people he just met. Regardless of the niceties. He didn't believe anyone was ever obliged to hand out their name simply for a social courtesy but… this girl did ask him for it. He supposed it'd be an asshole move to not do something so simple as to give his name. "It's Rin."

"Rin." The girl repeated, and she laughed breathlessly, "You're that guy from the recent swim competition right? I've—I've seen you at the community gym volunteering with the kids. My little brother attends the program. And after you broke that record, everyone's been talking about you."

"Me?" He slowly pointed at himself.

"Yeah, you were amazing!" The girl fiddled with the volleyball, rolling it between her hands. "There's murmur around town that you're a rising star who might make it to the Olympics someday soon."

"Well, that's the plan." He smiled, rubbing the back of his neck. Staying out under the sun for too long without sunscreen was making his skin heat up.

"Ah, listen, I—I was wondering if you would, um, like to play with me?—Us, I mean." Shifting her feet, Ami jutted her hip out to prop the ball against it. "Play with us."

"Volleyball?"

Ami nodded, an excited smile spreading on her rosy cheeks. She fixed a blonde pigtail over her shoulder, glancing back at her group of lady friends staring at the two of them with the same excited smiles. She tucked a blonde strand behind an ear. "We just—we don't have enough players."

"Um.." Rin glanced over his shoulder, quickly scanning the beach for Gou.

"And, well, you look capable." Ami said, giving Rin another appreciative once-over. She cleared her throat. "Capable in volleyball, I mean. You know, with—with those muscles—ahem. Your body—I mean, you have a lot of stamina, don't you? And, well, volleyball requires a lot of that—endurance."

Distracted, Rin glanced back again, barely hearing the girl's mumbling. A flash of fiery garnet hair caught his eye and he glimpsed Gou wandering by the wall of the cliff. She was trailing her hand against the rocky surface of the wall, almost absentmindedly.

"Are you looking for someone?" The girl spoke up again. Her voice was less excited when she asked, "Your girlfriend?"

"Um, yes." Rin automatically answered. He quickly met the girl's eyes in alarm. "No! I mean, she's my—I'm looking for my sister."

"Oh!" The smile returned to Ami's face. "Little sister?"

"Yeah, look, I'm sorry, but I gotta go." The smile dropped from her face and Rin pointed to a random dude. "That guy looks, ah… capable."

The random dude turned out to be a middle-aged man with a scraggly beard and a potbelly he was in the middle of itching. Rin tried not to cringe at his mistake but the girl just laughed.

"It's okay, I understand." Ami's brown eyes twinkled with interest. "Your sister must be really lucky to have a reliable older brother like you."

"Ah, thanks." Rin smiled back at her. As much as he liked the compliment, he didn't think he deserved it.

"So, hey," Ami drew a small circle into the sand with her foot, "maybe I'll see you at the community gym?"

"Actually, this week is my last." He explained, fighting the urge to turn his attention back to Gou. "I used to study abroad while training in Australia but I transferred to a university here for the year."

"Oh, where do you school?"

Rin didn't think someone he just met should be privy to such information. Instead, he pointed over his shoulder, "Sorry, I really think I should go…"

"Ah, yeah, of course!" Much to Rin's relief, she began to step away from him. "I'll let you go now. It was nice talking to you, Rin."

"Yeah." Was all he said. Disappointment passed through Ami's eyes before she smiled at him and left. He watched the woman retreat back to her group of friends before returned to face the tide. Damn, it was hot today.

Shading his eyes with a hand, Rin squinted at the cliffside in search of Gou. Not finding his sister where he'd last seen her, he scanned the beach. It was mid-noon and the tide was moving faster than when they'd arrived. Panic began to build in his chest as he skipped over head after head. Not a single one of them had that beautiful garnet hair he shared with his sister.

"Shit." Rin muttered, quickly gathering up their supplies and closing up the umbrella. He stuffed everything under his arms or over his shoulders. Then he hauled ass, racing back to the parking lot, nearly stumbling his way up the slope. His hand shook slightly while unlocking the car. Once Rin opened the door, he practically tossed everything in before slamming the door and locking it. He expertly slid back down the slope. Sand kicked up behind him as he sprinted to the edge of the water.

Could she have…? No, Gou wouldn't dare enter the water. Not when she couldn't swim for her life. Her fear of deep water would always stop his sister from taking a dip.

"But then where could you have gone?" Rin muttered, frantically turning this way and that in the hopes of catching a flash of rosy hair. Nothing.

Fuck. He shouldn't have gotten distracted by that girl. Should never have left Gou all alone. Again.

I'm such an asshole.

He gripped the rocky face of the cliff, trying not to punch it in anger. The bare skin of his back was beginning to itch under the sun, irritating him further. Shit, shit, shit, shit, shit! Rin spun towards the coming tide and kicked at the water, barely missing the side of the cliff. Panting, he stopped and leaned in to peer closer into the water. There was a small rocky path that skirted around the cliff. The sea had washed it flat enough to be walked upon, like a little pathway.

The last time Rin saw his sister, she'd been walking along here, trailing her hand against the rocks. Perhaps…?

He took a step forward onto the hidden pathway. The water was deep enough to submerge him halfway up his knees. Holding to the cliffside, Rin followed the narrow path. It was just barely wide enough for one person to walk through.

The tide receded until only his feet were submerged and he took the chance to move faster. When the tide came back, Rin slowed down, sticking close to the wall. He'd left his slippers back in the car, knowing he'd move more efficiently without them. Even without the slippers, the rock path was still slippery. He wondered if his sister was okay.

"Gou?" Rin called out, carefully stepping around the sharp corner of the cliffside. He found himself facing an empty lot of sand. It was a part of the beach that was divided from the public area by the large cliff. The squeals and laughter of the people on the other side of the cliff were farther away at this point. Here, it was peaceful and private, and— "Gou!"

Her back was to him as she walked by the edge of the tide a few meters away. A small, straight line of footprints trailed in her wake. The imprints disappeared, and then reappeared every time the tide returned.

"Gou!" Rin shouted again, running down the remainder of the pathway. His shoulder scraped the rocks and he winced, but didn't slow down. "Gou!"

Finally, she pivoted around at the sound of her name. Her foot twisted awkwardly in the thick of the sand and Gou began stumbling backwards for a fall. With eyes widened in surprise, Gou threw her arms up instinctively. Dashing forward, Rin managed to grasp her wrist, catching his sister just in time.

"You scared me." Rin hissed, chest heaving for breath as he tugged Gou into his arms.

"It—it's just sand?" She spoke, voice muffled against the hard pec of his chest. "Onii-chan, you're crushing me…"

"What the hell are you doing here?" He demanded, moving back to get a proper look at her. "Gou, the tide rises around noon. What if—what if I hadn't found you? You can't swim and, once the tide sets in, you wouldn't be able to walk back the way you came from. You'd be stuck here on the other side—where no one can see you—for the rest of the day!"

"I.. I'm sorry, Onii-chan," Gou mumbled, her eyes too wide with innocence for Rin to bear, "I was going to tell you but…"

"But what?" He said sharply, holding her by the shoulders. She looked terrified, having never seen this side to her brother. Softening his gaze, Rin said in a controlled voice, "But what, Gou?"

His sister looked away, eyes lowering to the tan sand they stood upon. She dug a foot into the beige ground, burrowing her toes until just the tips peeked out. Furrowing her brows slightly, Gou said, "You were busy talking to a girl. I… I didn't want to disturb you."

Oh.

Oh, shit.

"It's not—" Rin sighed in frustration. "It's not like that."

"It's not like what?" Gou snapped, her frown deepening as she stepped back. Not this. He didn't need more distance between them. "Not like us? Of course not. She wouldn't be screwing her own brother…"

"Don't say that!" Rin grabbed her shoulders again but Gou shrugged him off.

She turned around, putting her back to him once more. To Gou's credit, her voice remained steady when she said, "Did she give you her number?"

"No." He grounded out.

"Shame." Gou crossed her arms, holding herself together. "You two would have made a cute couple. A normal one…"

Why was she saying this? Didn't his sister know that it hurt him? Didn't she love him anymore?

"Don't do this." Rin stepped forward, wrapping his arms around her. Hugging Gou from behind, he murmured into her ear, "Don't push me away. Whatever you're going through, share it with me."

There was a shaky intake of breath. Another tense moment passed before Gou finally twisted around to face her brother. He glimpsed her tearful expression before Gou buried her face against his chest. Feeling hot tears spill down his abs, Rin cradled her head as she wept freely in his arms. "I hate this. I—I hate feeling jealous of a stranger who doesn't know you like I do. I hate knowing that—that I could never be like that with you in front of everyone else. I hate that you're my brother!"

She spoke quietly, sentences breaking in between shaky breaths and sharp sobs. But her words were tightly strung together with anger and frustration. Soaked in so much jealousy that Rin could practically taste the bitterness rolling off his sister's tongue. And, worst of all, he understood exactly what she meant.

"How many times do I have to tell you?" Rin tipped his sister's chin up so she'd meet his eyes. He swiped his thumb across her wet cheek. "You will always have me. All of me. Brother or not. We don't need normalcy. Why do we have to follow society? Who the hell made up these rules about who we can love, and how much we can love them?"

Gou sniffed. "But what if you find someone you like more—"

"No. There is no one else I'd rather have than you." Rin said firmly. "I wouldn't risk doing this with my own sister if I didn't love her enough for it."

"Are you…" She hesitated, "Are you sure you love me as more than a little sister? I don't know what I'd do if, one day, you regret us."

Rin stared into her eyes, watching the tears build up the longer he let the silence stretch on. As soon as a single tear began rolling down her cheek, he leaned in and kiss it away. He tasted the salt on his lips, and Rin continued laying kisses across the apple of Gou's cheek.

"Mm! Onii-chan!" Gou gripped his bicep as her brother kissed at the corners of her eyes. "Onii.. stop…"

She started backing away, up the sand so they were farther from the water. But Rin followed after Gou like a dancer chasing his partner. Cupping her face in between his hands, Rin began kissing every tear-stained part of it. "Onii—mph!"

Gou gasped upon Rin suddenly pressing his mouth to hers. He took that opportunity to slide his tongue into her mouth, brushing her plump lips in warning first. A natural sweetness stained her lips, tainted by a taste of a melancholic saltiness.

"Don't!" She pulled away, bracing a hand on his chest. There was no way Gou could physically hold him back if he didn't want her to, but Rin allowed her to push him away. If only out of respect. Despite this, Gou's cheeks were tinted a dainty scarlet, and her half-lidded eyes were no longer full of tears but lust now. His sister touched a hand to her bruised lips. "We—we shouldn't—ah!"

Rin grabbed the hand bracing his chest, holding Gou as he stole another kiss. Burrowing his hands through her thick hair, he tilted his sister's head back, deepening the kiss. She moaned into his mouth and, sensing her legs weakening, Rin slowly guided them down onto the sand. The remnants of the strawberry soda Gou drank earlier had made her tongue taste like candy. He explored the cavern of her mouth, tasting the tangy flavor of strawberry pop.

"Don't…" Gou panted for air while Rin brushed the hair from her blushing face. "We're not supposed to… to do this here."

"We're not supposed to do this here." He repeated, stealing a third kiss from Gou's lips and drawing out another moan. She tilted her head aside, baring her neck, and Rin accepted the invitation by pressing his lips to the hot skin of her throat. He could feel her pulse, fast and steady, flutter against his kiss.

Knowing she was sensitive, Rin nipped at her neck, eliciting a sharp cry from her. He licked the small wound he'd inflicted on Gou's body before giving it a chaste kiss in apology. Her body seemed to shake with anticipation beneath him. Strung high on emotions and desire.

"Take off your jacket." Rin breathed.

She looked at him and whispered, "What are you going to do?"

"You know what I'm about to do." He answered in a low voice.

The blush on her face deepened and she quickly looked around them. On their own little private strip of the beach, the place was quiet. They could barely hear the people on the other side of the cliff, hundreds of meters away. The two siblings had found the rumoured secret spot. Now, they had it all to themselves.

"I can't." Gou said timidly. "Th-there's people around. A-and we shouldn't do this in public or—nn!"

Rin silenced her with another kiss. Grinning against her mouth, Rin thought he was beginning to like teasing her like this. His hands reached her shoulders and he slowly slid her jacket down until it plopped onto the warm sand behind her. After slowly guiding her to lay down on the jacket, Rin finally released Gou's mouth. She sighed as he did so, and he began kissing his way down her neck. Her skin was hot everywhere he touched her and he'd soothe it with a small lick here and there. The top piece of her maroon bikini blocked Rin from reaching the valley of her breasts. He bit onto the thin connection between the cups, tugging it in silent permission.

Gou bit her bottom lip as she let her brother untie the strings behind her neck. She hesitated for a second, then she arched her back to let Rin untie the strings there as well. Before he could remove the bikini top, Gou crossed her arms over her chest. "We.. we shouldn't be doing this here…"

"I know you want this as much as I do, Gou." Rin said, cupping her warm cheek so she'd meet his gaze. "I can see it in your eyes."

"I… I don't want to be horny." She whispered, struggling to say such a vulgar word aloud. "It's…"

"Are you ashamed?" He asked, and his sister nodded.

"I... " She squirmed slightly. "I don't like it when… whenever I think of you, I get all hot and bothered…"

"You get wet when you think of me?" Rin clarified for her.

Gou lightly bit the tip of her index finger, trying hard to hold back her embarrassment. He appreciated how honest and open she was to him, aware that she was still very shy regarding their relationship.

"It's weird…" She said in a small voice.

Gently, Rin placed a hand on her lower belly, caressing his palm against her warm flesh. He felt her tense under his touch, stomach tightening slightly. "Do you like it when I touch you here?"

She nodded, closely watching his hand touch her belly so delicately, and so lovingly.

Gou's breath hitched when Rin suddenly slid his hand into the bottom of her bikini and cup her there. Her knees knocked together as she closed her thighs, crying out, "Onii-chan!"

"Do you like it when I touch you there?" Rin asked her again, his face remaining tender, but sober as well.

Biting her lip, Gou nodded hard in answer. She took a breath, and then said, "Don't, Onii-chan. You—you know you're not allowed.. to touch me like that. Not.. not outside."

Ignoring her warning, Rin slowly rubbed his palm against her slit. Back.. and forth… back… and forth. Sloppy noises began echoing between the two siblings with every movement Rin's hand made.

"Ah…" With furrowed brows, Gou continued biting her lip to hold back her moans. "S-Stop.."

"You're soaking wet down here." Rin murmured, watching the wanton expression on his sister's face as he relentlessly caressed her pussy.

"It—uhn!" Gou struggled to speak and Rin knew she ached to grind herself against his palm. "It's.. a bikini..! It's supposed to—ahget w-wet."

"I see." Rin couldn't help but smirk at her excuse. Brushing the back of his hand down her hot cheek, he asked, "And do you like it when I touch you… inside here?"

Spreading the wet lips of her pussy aside, Rin deliberately dipped his middle finger into Gou until he was knuckle-deep. She arched her back in response, a lustful moan escaping from his sister as he curled that single finger inside. Rin had forgotten just how tight she was, and he could feel her walls squeeze down on his digit.

"Do you like it when I touch you inside?" Rin asked again, tucking a loose strand behind Gou's ear.

"Yes!" She hissed, thrusting her hips into his hand for more. Uncrossing her arms, Gou grabbed Rin's wrist and grinded down on him. He felt her clit against the heel of his palm but Rin took the opportunity to remove her bikini top, tossing it behind him. The rays of the sun had done its job, tanning Gou's skin just barely. There was a faint but distinguishable pale triangle around the rosy tips of her breasts where her bikini barely covered them. Rin traced the tanlines with the tip of his index finger and Gou shivered in return.

"Then why?" Rin asked before dipping his face down to lick a nipple. Hearing Gou protest weakly, he started again, "Why are you ashamed?"

While waiting for an answer, Rin pulled his finger out of her and popped it in his mouth, sucking it clean of her musky arousal. Gou remained panting, staring at her brother with need. He continued, his tone halting, "Is it because of me? Are you ashamed of me? Of being touched like this by your own brother?"

She shook her head.

"Then why?" He continued, "If something makes you happy, you don't need to be ashamed of it."

Rin waited patiently, although his heart beat nervously. The silence between the two seemed to stretch on forever until Gou cupped the back of his neck, pulling his face close to hers so she could whisper, "I'm not ashamed of you… I'm scared."

"Why?" He whispered back, caressing the edge of her brow.

His touch seemed to relax her and Gou replied, "I.. I thought you would be disgusted to know that my body gets really h-horny when I… when I think of you."

"Is that why you've been avoiding me since that fight?"

She nodded, "I'm sorry… I've been meaning to apologize but I.. I don't recognize my body anymore. I feel so weird when I'm around you and I—I got scared. It embarrasses me when I feel myself getting wet and I.. I can't help but want you… inside me…"

"Inside you how?" Rin purred, unable to help himself from teasing his sister.

She blushed in answer and Rin grinned victoriously, "Onii-chan, you know how…"

"Gou, you think you're the only horny one?" He spoke in a low murmur, his eyes flickering between Gou's mouth and her modest gaze. "I've been masturbating every day just so that I wouldn't snap one day and enter your room and fuck you where you lay. I know you don't lock your door at night when you sleep… and you should."

She shuddered at her brother's naughty idea. "Maybe that's why I don't lock my door. Maybe I want you to come in.. in the middle of the night.. And hold me down against the bed… It's those kinds of thoughts that.. Make me wet."

"Then the next time you're wet," He whispered into her ear, grazing sharp teeth against her ear lobe, "I'll take full responsibility."

"But… I-I feel like," She struggled to say the word, "like a slut…"

"Gou, the only man you've had sex with is me… and I hope it stays that way from now on."

She bit her lip, "But I don't like how I get wet so—so easily when I think of you. It.. I've never felt this way before.."

"Actually," Rin practically rumbled with pride, "it makes me happy to know I make you wet."

"Isn't it weird?" Gou still sounded unsure but also a bit more hopeful this time.

"Sex isn't weird." Rin lightly flicked her nose. Her innocence was just too adorable. "If it makes you happy, then don't be ashamed of it. Or maybe… maybe this a sign that, even though we're brother and sister, our bodies are compatible together."

"Com—Compatible?" She blinked at him.

"Well, it's supposed to be forbidden for siblings to have sex, even if they're in love." Rin smiled thoughtfully, wary of how the both of them had defied just that. "But if it's forbidden, then why was I able to enter inside you?"

"Isn't.. isn't that just a physical.. thing?" She asked, the tips of her ears reddening.

"But if Kami-sama really decided that sex or love between siblings was forbidden," Rin explained, "then wouldn't he make it so that it would be impossible for a brother to enter his sister, or cum inside her?"

"I.. I don't know." Gou hesitated. Truth be told, neither of them were very religious.

"So maybe the bodies of siblings are just compatible like that." Rin continued. "And that's why your body gets wet when you think of me. I think your body recognizes my touch and it knows..."

"Really?"

"I don't know." He grinned, unwilling to admit he was just playing with her. "Shall we test it?"

"... No…" Gou looked away from him, tightening her arms across her breasts. "Onii-chan, I want you to touch me like a lover but… I'm scared that, if you do, we'll be caught. All it takes is one slip-up. Because.. You're my brother..."

"I'm your brother." Rin mumbled back, kissing Gou lazily on the mouth. His hands slid down to the apex of her thighs.

"Don't…" Gou whispered, hands gripping his biceps as Rin leisurely tugged down the bottom half of her bikini. He tossed it over his shoulder, letting the bikini bottom join its matching top. "Please, Onii-chan…"

"Did you hurt yourself?" Rin asked once he noticed the little patch of scraped skin on her knee.

"Onii-chan, we have to stop…" She winced as her brother gently blew on her scrape before kissing the small scratch. When she was a child, Gou had scraped her knee and Rin had blown on it, promising that it would make the pain go away. She let go of his arm. "I'm—I'm your sister."

"You're my sister.." Rin repeated back, prying her legs open to nestle himself in between. His eyes took Gou in completely, absorbing how her face was flushed with desire and anticipation. He observed the pale skin covering the more intimate parts of her body, contrasting the skin tanned from exposure.

Rin's eyes flicked to between Gou's legs and he swallowed hard. Reaching down, he tugged open his black swim shorts to release the erection he'd been holding back.

This time, it was Gou's throat that bobbed when she lowered her gaze to where Rin grasped the length of his cock and pumped himself once. He was already completely firm, the entirety of his thickness stood up with urgency. The mushroom head of his tip dripped with precum and he thumbed his slit, spreading the milky substance all over his head for lubrication.

"Onii-chan," Gou begged her brother but she still didn't cover herself up, "please. We can't. Outside, we should behave properly as… as brother and sister. If anyone we know caught us like this.. They would think you're raping me."

"Because I'm your brother?" Rin said distastefully.

"Yes." Gou agreed sadly.

"Then," He hesitated, "let them think I'm raping you."

She blinked at Rin in astonishment for a brief second, as if she couldn't believe what he just said. "What.. did you just say?"

"Gou." Her brother took her hand into his own and kissed her knuckles. His face was serious as he said, "If anyone catches us—especially like this—promise me you'll tell them I raped you."

"What?!" She shouted, propping herself up onto her elbows. "Are you crazy?!"

"Just look at us, Gou." Rin indicated to the both of them. "You're lying naked beneath me with your legs spread open while my dick is out and pointing at your… Listen, what sells us out is how obvious it is that we're siblings. It doesn't matter that you're already eighteen and consenting. I'm your big brother—the older sibling. It'll be easier if you just place the blame on me."

"So what am I supposed to tell the cops?" Gou stared at Rin in fury but she was blinking back fresh tears. "Mr. Police Officer, my brother raped me. Oh wait, is it still rape if I wanted it? Rin, you can't just throw the 'rape' card around so lightly! Do you.. Do you know how serious that is?"
"Of course I do!" He said sharply. "But if it's to protect you then I'll do it!"

"Would you still do it if.. If that meant you could never see me again?" Her voice quivered at the end.

"If it's to protect you." Rin answered quietly.

"Then don't protect me!" Gou shouted. She crossed her arms again, not to cover herself but simply out of agitation. "I won't do it. I won't ever tell them my brother raped me because you can't! You said—you said that I have you. All of you. Well, I'm giving all of myself to you too! That's how it works when you love someone, idiot Onii-chan! You don't take—you give! And I'm giving my everything to you whether you like it or not!"

Her voice was louder than the crashing of the waves behind them by the time Gou finished. Rin could only kneel before her, his eyes wide in awe of his sister who had forgotten she was still naked. Then, a toothy grin slowly spread across his face and he broke into laughter.

"Wh-why are you laughing?" Gou pouted.

"I can't help it. You're too awesome for me…" Rin buried his face against Gou's belly in an attempt to stifle his chuckles. Once he finished laughing, he gingerly kissed her belly button and whispered, "Damn, I love you so much."

"W-Well, I told you already, didn't I?" Gou's face remained red as she slowly, deliberately spread her legs farther open for Rin. It was incredibly cute, the way she struggled to meet her brother's eyes when she stammered out, "If I have all of you, th-then you have all of me too."

Rin smiled fondly at her. He touched her belly again and caressed it once more, feeling the softness of her body beneath his rough palm. "I wasn't actually going to put it in you. At least, not right now."

"... Eh?" Gou blinked, feeling more confused than embarrassed.

"I don't have a condom on me at the moment." Rin explained to her, dipping the tip of his thumb into her belly button. "I left the box back in my room, under the last drawer of my bedside table. And a Plan B pill isn't cheap so…"

"Oh…" She tried not to sound so disappointed.

"Buuut.." Rin dragged a finger down the slight slope of her abdomen. She shuddered once his finger trailed between the wet lips of her pussy, producing a lewd, wet sound. "There are other ways I could pleasure you."


This was crazy. Absolutely insane. She was out of her mind!

And completely in love…

Here they were, two siblings, naked on the beach, and in broad daylight. This was wrong on so many levels. The risk terrified Gou but it also thrilled her. She wanted this. To be able to express her love to Rin in public, whether it be by holding hands, or simply kissing. But to have sex on the beach? It was a miracle they had discovered this secret spot. Still, the fear of being caught remained in the back of her mind.

But the desire to touch Rin and be touched by him was too overwhelming at this point. Finally, after three, arduous weeks of being touch-starved, now was their chance. They needed to make the most of it.

And, as much as Gou loved what Rin was doing to her, she wanted to try something new. Something that she heard men crazy about. Something she had done quite an extensive amount of… research.

"Actually, I.. I wanted to try something different."

"Mhm.." Her brother answered distractedly while he gave her belly more nips and kisses.

"Can I… um," It was hard to think with her belly being attacked like that. Gou drew up enough courage and said in a quick rush, "Can I give you a blowjob?"

Rin froze, and suddenly Gou found herself already missing the kisses and nips on her belly. She was too embarrassed to meet his eyes and she thought she could die from that embarrassment when Rin said dumbfoundedly, "What did you say?"

Forcing herself to take a deep breath and calm her nerves, Gou repeated, "Can I give you a blowjob?"

"I... " Rin blinked, still processing her request. He spoke slowly, hesitantly, as if he wasn't sure he heard her right. "If—If you want to…?"

She nodded, sitting up on her jacket.

"Wait, you want to suck my—" Rin stopped himself, pushing a hand through his garnet hair. A drop of sweat rolled down the side of his neck, travelling down the narrow crack of his abs. Even without flexing, his sculpted six-pack was well defined and eye-catching under the sun. Gou licked her lips at the sight. "How do you know what a blowjob is?"

"Onii-chan, I'm eighteen, not eight." She said flatly. "I just.. I just want to try it and, if you don't like it, then I'll stop."

"It's not about whether I'll like it or not." Rin rubbed the back of his neck. The locks of his hair were wet with sweat and they curled around the nape of his neck. Gou wondered what his sweat tasted like if she were to lick him there right now. "Do you really want to do this? I mean, it's a penis we're talking about."

"I know what a… p-penis is." She said in a mumble.

He raised a brow at her. "And you've had one in your mouth before?"

"When I.. when I tied you to the bed that time, yes." She sputtered. Her face was incredibly hot. Honestly, Gou had only took the tip of him into her mouth back then. She faintly remembered the bitter taste of his semen but only because she had wiped it from her face.

"And how much of me were you able to take in?" Rin inquired, as if he knew the truth even though he had only been half-awake at that time.

"I'll show you if you stand up." Gou managed to say, eyeing her brother challengingly.

He must have noticed her courage beginning to falter because Rin did as she commanded. His black swim trunks fell to the sand and Gou finally got a chance to look at her brother properly.

Golden rays of the sun lit up his tanned body. The little curves, notches, and dips of Rin's solid muscles cast slight shadows all over him. Gou reached out to trail a hand down the muscular ridges beneath his pecs. His serratus anteriors were so beautiful to look at.

All of her brother's muscles made Gou drool in appreciation.

His hips were deeply indented as proof that a competitive swimmer like Rin barely had any fat. The expanse of his stomach was taut. Every time Rin breathed, it seemed like his body was just naturally flexing itself. Like he breathed power in and of itself. She pressed her hand flat against the hard slab of his stomach, noting how small her hand was compared to Rin's body. In response, Rin shivered, and the muscles of his stomach seemed to roll in contraction. Sometimes, Gou completely forgot how incredibly hard her brother's body was.

Muscles so powerful and toned that not an inch of fat hid them. A telltale sign of how much effort and hard work he'd put over the years as a serious swimmer. Rin was perfect in every way.

Tracing south, Gou touched the deep indentation of his hips, following the curve of muscle until… She fell to her knees when the curve led to his penis. The length of his cock was still attentively erect and her face met the tip at level. Out of curiosity, she reached out and grasped the erection by the shaft.

Her brother grunted, but said nothing as Gou tried to wrap her whole hand around him. And failed. But it surprised her to discover that, although he had such a bulbous tip, his penis seemed to widen at the base. She could sort of feel it whenever he slid himself all the way into her, but she thought she'd been imagining it.

"It's really hot." Gou whispered against it, and Rin growled at the sensation of her hot breath fanning his sensitive tip.

Now that she was actually taking the time to observe and touch it as she pleased, Gou was surprised to discover just how hot a penis was. Especially when so engorged as it was now, the skin of it blushing with arousal. Even now, the size of it scared her and if Gou had still been a virgin, she would never believe something that large could fit inside her body. A thick vein bulged on the underside of his cock, and she couldn't help but trace the vein with the tip of her finger.

Rin made a choked sound but remained still.

"It's… clean." Gou accidentally voiced her thought aloud.

Rin's voice was tight when he quickly said, "I have to shave for swimming."

Of course. She wanted to face palm. Male swimmers tended to have not a single strand of pubic hair if they could help it. The less hair, the less drag in the water. Of course she knew that. Looking at Rin's penis directly under the light of the sun, however, made her forget such a trivial fact.

She wrapped her hand around his cock and gave him an experiment tug, glancing up afterwards for approval.

His eyes were half-lidded and simmering with heat when he murmured, "Hold it more firmly, like this."

Rin enclosed a hand over hers and tightened her grip on him slightly. Then, together, their hands moved so that the both of them were pumping his cock. She watched in amazement as more milky precum dribbled out of his slit.

"Why does it do that?" Gou couldn't help but ask.

"You're—nngh—you're really asking the science of a penis?" Rin tipped his brow at her again. He let go of her hand but she continued holding him, slowly pumping him for practice. "I dunno? I think it's for lubrication.. like, so it doesn't hurt as much when I penetrate you."

"Oh." Gou's blush returned and the two of them were quiet for a while as she returned to practicing pumping him.

Then her brother mumbled, "I'm sorry… It was painful when I entered you, wasn't it?"

She nodded but then added, "It's okay. I wanted it."

Rin frowned, running a hand through his hair again. Droplets of sweat clinging to the ends of his hair were flicked away in the process. There was a bit of hesitancy, or concern when Rin spoke up again, "Does it still hurt? … When I enter you?"

"A little." Gou admitted, and she gave her brother a small but reassuring smile. "Only when your tip goes into me though. Once you're all the way inside… it feels… perfect. It's all right; when you put it in me, my body, um, it sort of stretches. So that when you're inside me, my body can adjust itself to your… to your—um, size."

"You're saying I stretch you from the inside out… just so that your body can fit my dick inside you?" Rin said in summation. He had a deep frown on his face as if the idea wasn't as appealing as Gou thought it was. "That sounds painful."

"It's pleasurable." She couldn't help but smile at how blunt Rin could be. She returned attention to the task at hand, swallowing lightly in preparation. "I'm gonna lick it, Onii-chan…"

"O-Okay." He nodded, reaching down to tuck his sister's hair back. It made Gou happy to know that the both of them were equally nervous with what they were about to do. With the body her brother had, he could have any girl in bed. Yet, he had chosen her. His sister of all people. And Gou was thankful that, for some divine reason, Rin loved her just as much as she loved him.

In public, he was distant and impassive to Gou. He kept up the image of the cool, older brother who could knock anyone out for looking at his little sister the wrong way. And Gou liked that about Rin. She wanted him to show his most vulnerable self and intimate emotions to her only. So to any stranger, it seemed Rin could care less about Gou. But, as his precious little sister, she knew better.

"Am I your first, Onii-chan?" Gou couldn't help but ask despite already knowing the answer.

"Yes." He answered, placing his hand atop of her head assuringly.

Gou smiled, and kissed the tip of his cock, smearing her lips with his precum and eliciting a sharp gasp from Rin. Licking her lips, she then opened her mouth to take in his tip. Her brother hissed and the grip on her head tightened slightly. Trying not to smile, Gou carefully pressed the flat of her tongue against his slit, making sure her teeth just barely grazed him. She swirled her tongue around the head several times, tasting the bit of saltiness from his precum.

"Fuuuck." Rin groaned aloud and she peeked up at him.

Her heart skipped a beat when their eyes locked together. Rin's shark teeth grinded together as he stared down at her, cupping the back of her head with shaking hands. His eyes were glinted with unbridled lust and.. joy?

She wanted to make Rin feel good and happy. There was this determination in Gou that coiled tightly in her chest. Keeping her gaze locked with Rin, she took a deep breath through her nose and gradually relaxed herself. She thought back to all those tips and articles Gou had read some time ago about how to give a blowjob. That was a secret she would take to her grave.

Once she thought she was relaxed enough, Gou shifted forward, gripping his base as she slowly took more of his length into her mouth. She felt his tip bump the back of her throat and she stopped. Another deep breath through the nose and she took another inch of him in.

Above her Rin groaned and began murmuring, "C'mon, baby, c'mon… nnngh! Shit.. haah, haah, yes…"

Several minutes passed as Gou took her time slipping inch after inch of his cock down her mouth. Her jaw ached slightly once she finally took in all that she physically could, leaving just an inch or two from his pelvis.

I can.. I can feel Onii-chan's thing throbbing in my throat.

It was almost like a heartbeat. Closing her eyes, she tuned herself to the steady throb of Rin's cock. Her mouth was stuffed full, making any talking impossible. But she could swallow just fine if she kept herself relaxed. Every time she did so, Rin would grunt in response. The walls of her throat massaged him and her swallows convulsed those muscles around him.

Curious, Gou gave an experimental hum. It must have worked because Rin groaned louder, his eyes squeezing shut in ecstasy. From what she read online, men experienced pleasure through several of their senses, including sound. With that thought in mind, Gou moaned softly, letting the vibrations of her voice pleasure her brother.

He snapped his head back, teeth clenched in gratification as Rin raised his face to the sun. When Gou reached to cup the balls hanging between his legs, she felt his hands spasm against her head as Rin fought to keep himself from tugging her hair and slamming his hips.

It was strange, holding his sack in her hand. It was hot to the touch, and it almost seemed alive, with the way it contracted slightly. Fondling it or grazing her nail between the cleft drew out a hard shudder from Rin.

"Squeeze it.." Rin mumbled almost deliriously. "Gently.. Ah, l-like that…"

Still holding Rin's sack, slowly, Gou pulled a few inches away, her lips dragging around the circumference of his cock. She breathed slightly before slipping Rin back into her mouth, moaning slightly as she did so. It took a few tries to find a proper rhythm, but eventually, Gou was steadily bobbing her head up and down, sucking on him.

There was a lewd, sloppy suctioning sound as her mouth moved up and down the length of him, her lips tightly enclosed. Her saliva coated his girth, making it slightly easier to slide her mouth across. What did embarrass Gou was the small grunts and moans that escaped her every time she bobbed her head.

Her body felt weird too. The peaks of her breasts tingled, and something wet trickled down the inside of her thighs. She ached to reach down and touch herself, relieve the pressure building in the bottom of her belly. But Gou wanted to give her brother his release first. She wanted to be the one to do it—make him moan her name aloud—make such a powerful body bend to its needs and give in to her touch.

"Gou…" Her brother muttered her name, chanting it like a mantra or prayer. His hands fisted onto her hair but he had enough willpower to not pull or thrust his hips against her mouth. "Gou… Gou.. Ah…. Haah! Haah! Stop! Stop, I'm… I'm gonna—nngh!"

Gou heard Rin warn her but she continued sucking him, refusing to back away or suddenly stop. She took him all the way into her mouth until her nose almost touched his pelvis, lifting her eyes up to meet her brother's sharp gaze. His brows furrowed and he held the back of her head as he came inside her mouth. She felt a thick, ropy burst spurt into her throat. Something hot and gooey slid down her throat and she instinctively swallowed, letting it travel farther down into her.

His seed was hot and sticky, and Gou could practically feel it move down her throat and settle in the pit of her belly. Grunting, Rin shot two more thick ropes of cum, his hips quivering through the spurts. There was no bitter taste since he was too far down her throat, and she had to swallow several times for all of his seed—or at least most of it—to slide down her throat completely. Even when most of it seemed to settle in her stomach, her insides still felt sticky somehow.

When his cock became flaccid, Gou slowly pulled away until she could breathe through her mouth again. She gave one last kiss to his tip before finally letting go, licking her lips of his cum.

"Gou!" Rin cursed under his breath, pulling his shorts back up before kneeling to Gou's level and cupping face. His eyes were now full of concern as he looked his sister over. "Gou, did you swallow?!"

She nodded, wiping the back of a hand across her mouth just in case she had any leftovers stuck in a corner.

"You swallowed all of my…" Rin still looked concerned and Gou didn't understand why. "You shouldn't… you shouldn't swallow my semen, Gou…"

"I.. I thought it would make you happy?" She cupped her belly, still feeling the fading warmth of his seed inside her.

"Only if you're happy." Rin replied. He licked his thumb and wiped at the corner of her lips.

"I'm happy when you're happy." She retorted back, shrugging her face away from his hand.

"Funny, I was going to say the same." Rin gave her an exasperated smile. He cupped her cheek, and Gou suddenly felt self-conscious with the way he studied her eyes. It'd been quite a while since the last time they were able to do this. Be intimate with each other, and honest. Nothing to hide, and nothing to keep from each other. She was still getting used to all of it, and she didn't think she'd ever will. How could she ever get used to being in a relationship with her brother?

"Did you like it?" She asked when he kept staring into her eyes for too long.

His gaze flicked down to her bruised lips and his sharp teeth glinted when Rin finally grinned at her, "All right, that was pretty hot."

Gou broke into a proud smile, feeling accomplished and successful of her hard work. Giving a blowjob was not as easy as she assumed.

"But you scared me shitless when you swallowed my stuff." Rin added, his expression stern and, ironically, brotherly. "It's hot when you swallow my semen like that but I don't want you to hurt yourself."

Gou couldn't help but roll her eyes. "It's just semen, Onii-chan. Your semen isn't going to hurt me."

"No," He said slowly, but her brother made a pointed look to her belly, "But it could get you pregnant."

"Swallowing your seed isn't going to grow a baby inside me." Gou protested, too irritated to be embarrassed over discussing something so promiscuous. "When I was a little girl, you told me that if I swallowed an apple seed, a tree would grow in my stomach! Okaa-san wondered why I was crying when we returned home!"

At that memory, Rin started chuckling, pleased to know his ploy to trick his sister had worked.

"It's not funny!" Gou smacked her brother's shoulder lightly, but she too was smiling at the fond and innocent memory they shared as siblings.

"Hm, well, as hot as it is to watch you suck me off and swallow my stuff," Rin drawled out, tucking a loose strand of hair behind Gou's ear again, "I don't think it'll be hot anymore once you start gagging on me."

She smirked at Rin slowly, "So no more blowjobs then?"

"Hold on, now, I didn't say that." Rin leaned in until the tips of their noses grazed each other. "Whatever you want, I want too."

Smiling slightly, Gou bit her lip in hesitation. Her heart beat wildly against her chest as she summoned the courage to say her next words, trying to be as seductive as possible, "Sooo, if I wanted to do it.. anal?"

Rin met her shy gaze, surprise passing his face for a moment before he whispered to her, "Then we're going to need a lot of lube."

She felt her whole face and ears redden impossibly more, but then Gou said, "At least we won't need a condom."

Or worry about a pregnancy.

"I like the way you think."

"I have a good teacher."

"Hm," Rin's glanced down at her mouth again and he leaned closer to her, "Shall I teach you more?"

"Wait," Gou pulled back slightly, touching a hand to her mouth anxiously, "I just finished…"

"You sucked dick." Rin promptly stated without a care in the world. "My dick. Why would I be disgusted by that? If I want to kiss you, then I'll kiss you."

"But the semen—mn!"

Without waiting any longer, Rin kissed her, long and hard. If her soul could be drawn out with such a simple act of love, it would. The kiss was powerful and raw, enough to make Gou's whole body tingle with pleasure. Her nipples were hard and she could feel her arousal dribble down her leg in a thick, wet trail. The brisk breeze of the sea on her nude body felt like freedom as Gou curled into her brother's strong arms. With him holding her like this, she felt safe.

Nothing in the world could hurt her as long as she had her brother's arms holding her to him. Once Rin released her lips, the two siblings watched the steady pace of the tide in peace. In the corner of her eye, Gou saw her bikini abandoned on the sand. She didn't bother to put it back on though. Instead, she made herself comfortable on Rin's lap. It was weird to be naked out in the open but still feeling the most safe when in the arms of a loved one.

'I love you' she suddenly felt the desire to say. And it was a strange, foreign feeling, to suddenly want to tell a person that you love them. Strange, but pleasant. So, from the shelter of Rin's arms, she looked up at him and said firmly, "I love you, Onii-chan."

Rin gazed down at her, seemingly caught off guard by the unexpected confession. He had that look on his face again. That same look of longing whenever he studied her intently, too deep in thought for Gou to know what he was thinking. Then he brushed her hair back before giving her another kiss, just as she expected.

Suddenly, her brother swept Gou up into his arms as he stood up. She squealed in surprise and delight at being carried like a bride. Gou should have felt more vulnerable and embarrassed than ever, being naked before Rin like this under the sun.

She normally would have been, and Rin would gently coax her into uncovering her breasts, or to open her legs to him.

This time, she felt free and happy.

And Gou laughed, wrapping her arms around her brother's neck as he carried her to the dark area that the cliff provided at this time.

"Make love to me." She said quietly, but bravely once Rin set her down, spreading her jacket out for his sister to sit comfortably on.

"I don't have a condom." He reminded her.

"Then take me home," Gou suggested, and she touched Rin's hand, "and make love to me there."

"If we're going to go home," His eyes drifted down the length of her body and, this time, she didn't cover herself out of embarrassment, "then you're going to need to put your bikini back on."

The both of them looked to where her bikini lay discarded on the other side of their small, private beach.

She turned to Run, lips pouting slightly as she silently begged her brother to get her bikini for her. He smirked. "Uh uh, you get it."

He was doing this on purpose, knowing she'd have to walk naked before him in order to retrieve her clothes. He'd get the perfect view from the back and the front.

"Fine." Gou huffed, heaving herself onto her feet. She could feel her brother still smirking behind her but Gou held her head high and walked as confidently as possible. It took all of her concentration to pretend she wasn't fully naked and out in the open. Nope! It was just her and Mother Nature.

"Beautiful day, beautiful day…" Gou chanted to herself as a distraction until she reached her bikini. Snatching both pieces from the ground, she brushed the sand off them before hurriedly slipping the bottom on. She nearly fell while trying to get one foot through a leg hole. And then she was tying the top piece back on as quickly as possible, her fingers fumbling with the knots.

Beautiful day. Beautiful day…

She swept her hair back, shaking bits of sand out from between her locks. Finally turning around, Gou walked back to her staring brother.

"Pervert." She said when he stood up to return her jacket. She put it on and took a step when, suddenly, Gou found herself swaying to the side. Her vision tilted at a horribly wrong angle as she started to fall.

"Hey!" Her brother caught Gou immediately, one hand holding her arm and the other supporting her back.

Sucking in a breath, Gou held still until the world stopped spinning around. She heard Rin ask, "Gou? You all right?"

"Hm, yeah." She eventually nodded, taking in a deep breath. "I just felt woozy all of a sudden. That's all."

"You've probably been under the sun for too long." Rin explained, pressing his hand onto her forehead and frowning in worry. His concern touched Gou and she was slightly disappointed when he removed his hand from her skin. But then she smiled when her brother turned around and kneeled, his arms reaching back for her in gesture. "Get on."

It'd been years since Rin had offered a piggyback ride to Gou. He had once told her it was privilege reserved for only the most well behaved little sisters. On the day she had scraped her knee, however, Gou vaguely remembered her brother carrying her through the thick snow for an hour. All the way until she was comfortably sitting on the sofa and Rin was limp on the floor from exhaustion.

Giggling quietly at the memory, Gou climbed into her brother's back, wounding her arms around him tightly. From behind, she saw his ears redden and she wondered why until Gou realized it was because of her breasts pressing against his back. As he stood up, Gou hugged Rin tighter and then gave him a kiss on the cheek.

"What was that for?" He turned his face aside.

His shaggy, maroon hair tickled Gou's nose and she leaned in to smell the warmth of the sun on him. "Hm, a thank you."

Rin only grunted in response, but Gou felt his hand slowly caress the underside of her thigh. She nuzzled her face against the hot skin of Rin's neck and closed her eyes, letting her brother take her home once more.

"By the way," Rin asked while driving, "what time did I get home last night?"

"Sousuke brought you home around a little past two last night." Gou answered, caressing her thumb across Rin's knuckles. They held hands between their seats while Rin maneuvered through traffic, their fingers interlocked together.

"Did I…" Rin paused briefly, "I don't remember last night but I didn't do—or say—anything weird.. did I?"

Without missing a beat, Gou smiled faintly and said, "Nope, you slept like a baby, Onii-chan."
