Side Story: Keeping Heads Above Water with Aoi and Yuta Asahina

It was about noon when Aoi Asahina, also known as Hina the Ultimate Swimmer, finally woke up from her long night’s sleep. This was normal for her, though, since her job regularly required her to work late into the night, plus she had a very strenuous workout regimen, so sleeping in was practically required for her to regain all her energy. She was wearing a pair of pristine white panties and a light white tank top that fit very snuggly over her large tan breasts, though that was hard to see under the light blue blanket she was sleeping under. The room itself, like the rest of her apartment, was very small and not very well furnished. All she had was a wooden dresser filled with all her clothes and swimsuits, a small mirror on the wall for fixing her hair, a few different pairs of workout shoes on the floor, and a closet that was mostly stuffed full of different kinds of workout equipment, like weights, water bottles, and balls. She would have liked to own more, but this was all she could afford when she moved out of her parents’ place.

When her eyes fluttered open, Aoi checked the time on the digital clock next to her and sat up in her bed, her long brown hair flowing freely behind her as she stretched her arms. Once that was done, she walked over to her jet-black curtains and pulled them open, allowing the sun to shine into the room and keep her company as she did her morning stretches.

“Aaaah… another day, another doughnut,” Aoi said to herself as she carefully stretched her fit legs. “Let’s see… I think those two regulars of mine hired me for some hot tub treatments, and then I should be free to work the streets for as long as I want. Hopefully I’ll be able to get back home in time to hang out with Yuta a little.”

Once her body was properly limbered up, she went outside to her kitchen to cook herself up some breakfast/lunch in the form of a protein shake, some fresh vegetables, and a massive glazed donut for dessert. She started put all the veggies in a pot to boil and was right about to mix up her protein shake when she noticed that she wasn’t alone.

Sitting in a small chair on their incredibly tiny balcony was her brother, Yuta Asahina, who was currently staring out at the surrounding cityscape. The eighteen-year-old boy looked remarkably like his sister, with a remarkably fit body, blue eyes, tan skin and brown hair. The only real differences were that Yuta cut his hair much shorter, to simply neck-length, and his chest as flat and muscled instead of round and supple. At the moment, he was wearing a white T-shirt, brown pants, and his favorite pair of red running shoes.

“Oh, hey there, Aoi! How’s it going?” Yuta asked casually when he noticed his sister, not minding her current state of undress.

“I’m doing pretty well, actually, but… what are you doing here?” Aoi replied curiously. “Don’t you have to work today?”

“Actually, my boss said she’s having her baby shower today, so she let everyone go home early,” he replied with a smile. “I got back just a few minutes ago to change and say ‘hi’.”

“Really now?” Aoi raised an eyebrow. “You wouldn’t happen to be the cause of that baby shower, would you?”

“What!?” Yuta gasped in shock. “No, no of course not! Probably…” He whispered that last word to himself.

His sister just stared at him with a pout on her face and her arms crossed, clearly not totally convinced.

“A-anyways, I’m actually pretty grateful for the time off. I’ve barely gotten the chance to jog around the neighborhood since I moved in with you.” Yuta turned back around and began pointing at places beyond the balcony. “Like, I still haven’t been down that street, or by that plaza, or in that park. That place must be great, because I see some really pretty girls hang out there sometimes. Oh, I think I see one now! I should go say ‘hi’ to her when I jog by the park. I wonder what shampoo she us-gh!”

Yuta as abruptly cut off by the feeling of his sister putting him into a tight headlock from behind.

“Brother, dear, what did I say about talking to girls that you think are ‘pretty’?” Aoi spoke with a chipper tone and a smile on her face, but the frustration and venom in her voice was unmistakable.”

“Th-that I should only talk to them if I have to.” Yuta grunted in discomfort. “But I’d just be saying ‘hi’, I swear!”

“Sorry, but our wallets are already straining as it is, and I don’t want to take any risks,” Aoi said as she let her brother go. “When I’m done eating, I’m going to go out to work for a few hours, and I want you to promise me you’ll stay here at the apartment until I get back. Then, we can go out jogging together.”

“Whaaaat!?” Yuta gasped dramatically. “But sis, I can’t wait that long. I’ll go stir-crazy! I won’t knock anyone up while you’re gone, I swear! Can’t you trust me?”

Aoi sighed. “I’m sorry, Yuta, but I don’t want a repeat of that incident with those roller skater girls at my birthday a few months ago.” Aoi pouted again and placed a stern finger on her brother’s chest. “Promise me you won’t go out, and that you won’t have sex with any women while I’m gone… or if you do, at least promise me you’ll use a condom. I got you that big box of them and you still haven’t even used one.”

“Augh… you can be so cruel sometimes, Aoi…” Yuta’s arms and shoulders slumped in sadness. “Alright, I promise.”

“Heh, thanks, Yuta! That means a lot to me!” Aoi pulled her brother into a tight and loving hug before returning to her boiling vegetables. “You know, I wouldn’t bother you as much about this if you just went ahead and got that vasectomy.”

“Whaaa!” Yuta reflexively covered his groin with his hands. “D-don’t even joke about that, sis!”

“Well then, I guess we’ll just have to keep being careful then!” Aoi replied. “Don’t worry, I promise I’ll be back as soon as I can, and then we can spend the rest of the night having fun together. I’ll even let you race me across town if you want.”

“Wha-, really!?” Yuta’s face lit up like a puppy with a treat being dangled in front of it. “You mean it? All the way across town?”

“Yep! I could use a little extra cardio.” Aoi smiled, knowing that her brother could easily lap her at any foot race.

“Aw, sweet! Thanks so much, sis!” Yuta jumped up in excitement. “I can’t wait!”

“What a sweet, simple boy,” Aoi thought to herself as she ate her lunch. “It’s just a shame that he can be a bit too simple for his own good.”

When her meal was done, Aoi returned to her room and donned her work clothes, including a pair of red high heels, her signature ponytail, her eye-catching keyhole swimsuit, and a long red jacket to keep herself modest while she rode the bus. She then grabbed her red gym bag, which was stuffed with swimming equipment and lube, and headed towards the door of her apartment.

“Alright, Yuta, I’m going now!” Aoi called out to her brother as she opened the door. “Remember your promise, okay?”

“Don’t worry, I will!” Yuta smiled and gave Aoi one last wave goodbye before she closed the door behind her and left.

The Ultimate Swimmer walked to the nearest bus stop and took the next bus to one of the richer parts of town to an upscale house where two of her clients had agreed to meet her; Mr. Iseri and Mr. Tatsuno. The men were both a little older and chubbier than Aoi personally preferred her men to be, but they were reliable, respectful, and they paid well, so they were practically dream customers to the young escort. Plus, Mr. Tatsuno had his own private pool and hot tub at this house, which meant she always had at least a little bit of fun when they hired her.

“Ah, Ms. Hina!” Tatsuno greeted as he opened the door. “It’s good to see you again.”

“Likewise, sir!” Aoi walked in and took off her coat and shoes, revealing her toned body and tight swimsuit to the man. “So, we’re just doing a normal routine today, right?”

“Indeed; and, as always, you’re free to swim as much as you want when we’re done,” he replied.

“Hehe, you’re too kind, Mr. Tatsuno!” Aoi kissed the man gently on the cheek and walked out to his back yard, which was surrounded by a nice high fence to keep things private. There, his friend Mr. Iseri was already waiting in his hot tub, completely naked. “Hey there, Mr. Iseri! I see someone couldn’t wait to get started!”

“What can I say? Knowing that you’re going to be coming around gets me in an aquatic mood,” he replied.

“That’s good, because just thinking about being here gets me more than a little wet~” Aoi put down her gym bag and climbed into the hot tub, kissing Iseri deeply as she pulled herself onto his lap. He eagerly kissed back, rubbing his hands across her body as she ground herself into his lap. She let out a soft gasp as she felt the warm water jets of the tub massage her body and man’s soft cock start to harden underneath her. Soon, it was rubbing between her taught ass cheeks, and she did her best to massage it as the kiss kept going.

“Room for one more?” Tatsuno asked as he took off his own clothes.

“Of course!” Aoi replied. “Come on in, the water’s fine!”

As Tatsuno got into the hot tub, Aoi turned around and gently moved the bottom of her swimsuit to the side and pressed Iseri’s shaft into her tight pussy. She let out a long sensual sigh as her walls clamped down lovingly around the throbbing pole as she settled in on his lap. With his meat nice and snug inside her, Aoi took a deep breath dove forward into the water in front of her, bringing her lips right up against Tatsuno’s shaft. Her eyes were closed, but she could feel he was already hard, so she opened her mouth and swiftly sealed her lips around his throbbing cock. Her tongue then began to swirl around Tatsuno’s dick, sliding along all his most sensitive spots while her hips began to move up and down on Iseri’s lap. She kept this up for a little while, her strong swimmer’s lungs allowing her to keep the act going much longer than just about anyone else could have.

“Pah!” Aoi gasped as finally came up for air, though she made sure to keep her hips thrusting behind her. “So, how am I doing?”

“You’re doing great, Ms. Hina!” Tatsuno replied, caressing her cheek. “Absolutely wonderful as always~”

“You still think I’m a fresh fish? I’m so flattered~” The swimmer fluttered her eyelashes and pulled herself upwards, allowing the man to kiss her on the lips. At the same time, one spare hand reached back down towards Tatsuno’s shaft and began to gently stoke it, her fingers working together with the swirling hot water excite him even more.

Iseri, meanwhile, reached around her chest and squeezed Aoi’s large breasts hard through her suit, making her moan into Tatsuno’s mouth. He then used his grip to thrust into the tan escort even harder, making her bounce up and down in the water like provocative buoy. The swimmer savored the sensations and did her best to keep pace, even with her attention split between the two men.

“Mmm, you two are being so feisty today! I like it~” Aoi flirted when she broke the kiss finally broke. “Did you guys miss me these past few weeks?”

“Yeah, we did,” Tatsuno replied, his dick throbbing in her hand. “This pool is place is just so lonely without you~”

“Well then, I guess you’ll just have to hire me more often then~” Aoi replied, playfully wiggling her hips as the sun made her wet skin shine like polished bronze.

“Heh, I wish we could! Then this place could be paradise!” Iseri replied just before his thrusts grew more ragged. “Ah! Hina, I’m getting close!”

“Go right ahead, sir! Stuff me as full of your little swimmers as you can!” Aoi doubled the pace of her thrust, slamming her sculpted ass down hard on her client’s lap again and again until she finally felt his dick suddenly spasm and unleash his scalding load deep inside her. “Oooooh, yeah… that’s it~” When she felt him slip out of her, Aoi carefully placed her hand over her pussy so his seed wouldn’t spill out and carefully pulled herself out of the tub. “Great job, Mr. Iseri! I really felt that one!”

“Thanks, Ms. Hina,” the man panted as Aoi went to her bag to clean herself up. “It was all because of those amazing hips of yours, though. I can tell that they’re stronger than ever!”

“Hehe, you’re too kind!” Aoi said as she finished cleaning out her pussy. “Alright, Mr. Tatsuno, I think you’ve waited long enough in the shallows. It’s about time you entered the deep end~ What do you say we have some fun on that pool float of yours?”

“Hina, you read my mind~” he replied, already getting in the pool.

“Aaaaugh…” Yuta groaned as he stared at the ceiling of his apartment, not paying attention to the TV that was on in front of him at all. “When is Aoi getting back? It feels like she’s been gone for forever!” He turned slightly and glanced at the clock on the wall. “She’s only been gone two hours!? Aw, at this rate, I’m going to explode from boredom… there’s got to be something more exciting I can do.”

Yuta sat up and placed a thoughtful hand underneath his chin.

“Hmmm, Aoi said that I couldn’t leave the apartment… but the whole apartment building is technically part of the ‘apartment’ isn’t it?” he said to himself. “She won’t mind if I do a few warmups around the building before we go jogging together… yeah, that’s a great idea!”

Yuta quickly stood up and did some stretches before heading towards the door, passing by his box of condoms on the way. He saw them and almost reached out to grab one, but he stopped himself at the last second.

“Well, Aoi said I shouldn’t be having sex at all, so carrying one of these around would be pretty pointless, wouldn’t it?” Yuta said to himself by the door, imagining how uncomfortable it would be in his pants pocket. “Plus, I’m just going to be exercising by myself, with no pretty girls around at all. So, I’ll be perfectly safe!”

Yuta walked outside with a smile on his face before locking the door and taking off running down the halls of the apartment building. He made great time, running all the way from the basement to the roof several times without so much as breaking a sweat. He did, however, make quite a bit of noise running around, and it didn’t take long for one of his neighbors to take notice.

“My my my… what’s with all the running?” An older woman with long pink hair, a pearl necklace, a blue jacket, and torn brown pants asked as she stuck her head out from behind her apartment door. “There’s not a fire, is there? I hope not; too much heat will ruin your hair.”

“Huh?” Yuta stopped in his tracks and turned to the woman. He almost didn’t respond to her, remembering what her sister said about cute girls, but then he realized that he did have to talk to her. She was his neighbor, after all, and ignoring her would have been extremely rude. “Oh, sorry! Nothing’s wrong, I’m just exercising is all! You know, jogging!”

“Really? Here?” The woman asked curiously, stepping out into the hall. “Don’t people usually do that at the gym, or outside?”

“I, uh, just thought I’d stay in today!” Yuta replied, not wanting to explain the promise he made to his sister. “My name is Yuta Asahina by the way. I live down the hall, in apartment 53.”

“Yuta, eh?” She looked the boy up and down, her expression casual but with something lurking behind her eyes. “You can call me Hiroko. It’s nice to meet you.” She extended her hand to shake.

“Hiroko… wow, what a pretty name!” Yuta smiled his sweet, innocent smile and shook the woman’s hand eagerly. “It fits you so well too! You look so graceful, and your voice is so sweet, and you smell so nice!” Despite how obviously flirtatious Yuta sounded, he honestly wasn’t trying to hit on her; this was just how he spoke with women, and he never saw anything unusual about it no matter how many times his sister berated him for it.

“Why thank you. I see you have very good taste.” Hiroko looked the boy up and down again and moved her lips from side to side as if she was twirling something between them. “You’re not half bad yourself, you know. Say, you look a little bit… hot. Why don’t you come in for a bit and I can get you a glass of water?”

“Wow, really?” Yuta’s eyes sparkled. “That would be fantastic! Thank you! You’re the nicest, prettiest lady I’ve met in this whole building!”

“And you’re the most strapping young man I’ve seen in this whole city,” Hiroko said as she held open her door for him. “Please, make yourself at home.”

The apartment smelled faintly of cigarettes, but it was it was much more well-furnished than Yuta and Aoi’s apartment, with a new couch, a wide-screen TV, and lots of framed pictures on the wall, most of which had Hiroko in them. He looked at them all curiously as Hiroko poured him a glass of water and handed it to him.

“Mmmm…. Aaaah, that’s refreshing.” Yuta sighed as he finished the glass. “So, who are these people in all these pictures? Are they your family?”

“Well, yes and no,” she replied before pointing to one of the pictures. “Do you see this one here, with the stubble and the curly brown hair? That’s my son, Yasuhiro, but he moved out a few years ago. He stops by to chat occasionally, but I still miss him a lot.” She then moved to another picture that was hidden away in a corner, which featured Hiroko standing next to a man with short black hair who didn’t look anything like Yasuhiro. “And this was my first husband, but we broke up shortly after my son was born. You can probably guess why.”

“What? No, I can’t!” Yuta replied. “Why would anyone break up with a woman as amazing as you? You’re so kind and beautiful… and people call me an idiot.”

“Heh, thanks kid, but I don’t really blame him,” Hiroko replied before pointing to another dark-haired man in a business suit in a newer photo. “That, right there, is my current husband – though it hardly feels like it most of the time. We had a nice honeymoon, but after that he’s barely even touched me. And now we’ve both gotten older, and I probably can’t have any more kids… so much wasted time.”

“He doesn’t want to touch you? But what kind of person wouldn’t want to touch a cute girl like you? Your skin looks so smooth, and soft after all! I can tell you put a lot of work into taking care of it!” Yuta replied. “You use green tea in your lotion, don’t you?”

“Wow… yes, I do actually. You’re the first guy I’ve ever met to notice that.” Hiroko’s smile widened. “Say, kid, if you really think so highly of my body, then I’ve got an offer for you. I give you six hundred yen and you massage the kinks out of my back. What do you say?”

“Are you kidding? I’d be honored to massage you, ma’am!” Yuta replied.

“Perfect… follow me.” Hiroko led the young athlete to her bedroom, where she promptly took off her shirt, coat, and bra, and laid down on her stomach on her bed. “I hope you don’t mind if I do this topless.”

“No, not at all! This will help give me access to all your muscles, after all!” Yuta crawled onto the bed and casually straddled the older woman’s rear. There, he pressed his fingers hard into her soft back and began to knead her muscles, slowly working out all the tension in them with his fit fingers. “Wow, you really do have a lot of kinks in here! Are you stressed a lot?”

“Hmmm, a little bit~” Hiroko purred as she enjoyed the sensation of Yuta touching her body. “Being a housewife is kind of boring, especially since my husband’s never around, so I sometimes work as a bartender at night. It can be fun, but sometimes the customers can run me ragged.”

“Really? It sounds to me like they don’t appreciate what nice lady you are,” Yuta commented as he reached her lower back.

“Yeaaah, they don’t… but you clearly do~” Hiroko looked back at Yuta and winked, and he smiled back even though he just assumed it was a normal blink. Yuta kept rubbing for a while, enjoying the feel of her body and loving the moans and gasps of happiness she made even more. After fifteen minutes, though, she suddenly felt his fingers stop.

“Alright, miss, I think I got everything!” Yuta said proudly as he wiped the sweat off his forehead. “Do you need help with anything else?”

“Everything? Are you sure about that?” The pink-haired woman turned herself around underneath Yuta and placed his hands right onto her soft, bulbous breasts. “Why, you haven’t even done my front yet~”

“M-Miss Hiroko!” Yuta blushed wildly as his fingers dug into her soft titflesh and he finally noticed Hiroko’s sultry tone of voice. “Are you sure we should be doing this? This seems… kind of sexual.”

“So?” The older woman asked casually, staring up at the boy as Yuta kept his hands on her breasts. “Are telling me you don’t want to have sex with me?”

“Actually… I do. That would be a lot of fun, but… I told Aoi-“ Yuta said, only to be silenced by a finger to the lips.

“Shhhhh,” Hiroko shushed. “Let me guess… responsibilities?” Yuta nodded. “Well I’ve got responsibilities too, and you don’t see that stopping me, do you, hun? So why don’t you just spend some time with me, and we can forget about the world… together~”

“This isn’t good… I told Aoi I wouldn’t have sex, and I left the condoms back at our place!” Yuta thought worriedly to himself, sweating ten times as much as he did during us jog. “But… she did say earlier that she couldn’t have kids, right? Yeah, yeah! She did! That means I don’t have anything to worry about.”

“Alright then… let’s do it!” Yuta said with his brightest smile yet. “Let’s have lots of fun together, okay?”

“Well, if that bulge in your pants is as big as it feels, I don’t think we’ll have to worry about fun at all~” Hiroko replied before pulling him forward for a kiss.

“Ten thousand, twenty thousand, thirty thousand…” Aoi spoke to herself as she counted up all the money she had made during her elevator ride back to her apartment. “Hmph, that’s a pretty good haul for only a few hours. We might even be able to get the child support checks sent out early this month.” She then stuffed the cash into her red jacket and walked the rest of the way to her apartment.

“Hey, Yuta, I’m back! We can go work out together now!” Despite her shouts, her brother didn’t reply, and she couldn’t find him in any of their rooms either. “Wait… where did he go? Yuta? Are you here?”

The young swimmer listened carefully and, over the soft hum of air conditioners outside, she could hear something in the distance; grunting.

“Oh no.” Aoi dropped her gym bag on the floor and dashed out the door, following the noise to its source. “Please don’t be what I think it is, please don’t be what I think it is, please don’t be what I think it is…!”

She reached the apartment where the noise was coming from and found the door wasn’t locked. She then dashed inside and went straight to the bedroom, where she arrived just in time to witness her brother slam his hips one last powerful time into Hiroko and fire his seed deep inside her.

“Noooooo!” Aoi immediately slapped her palms over her eyes and dropped to her knees. “Auugh, this can’t be happening!”

“Oh! Hey, Aoi! You’re, uh, back already!” Yuta did his best to sound casual as he pulled out of the pink-haired woman beneath him and covered himself with a blanket.

“Oh dear… who is this?” Hiroko asked with worry as she covered herself up as well. “She’s not your girlfriend, is she?”

“No, she’s uh… my sister actually,” Yuta replied with an embarrassed blush.

“… I honestly don’t know if that makes it better or worse,” Hiroko replied.

“I can’t believe this, Yuta!” Aoi groaned, still on her knees. “What was the one thing I told you not to do while I was gone?”

“H-have sex with a cute girl…” Yuta could feel shame start to set in, but he was doing his best to keep up his chipper demeanor. “But don’t worry, it’s fine! Ms. Hiroko said she can’t have kids anymore, so there’s no chance I impregnated her!”

“Really?” Aoi lowered her hands from her face with a hopeful glint in her eyes. “Is that true?”

“Well, I do technically have a few eggs left in me, but I haven’t had any luck with them in decades, no matter how hard I’ve tried.” Hiroko replied. “So, your brother is probably safe.”

“Oh no… you don’t understand! I promise, if there’s even the slightest chance you could get pregnant from this, no matter how slim, it’s going to happen. Trust me,” Aoi said before she suddenly noticed the wedding band on Hiroko’s finger. “Wait… you’re married!?”

“Augh, don’t remind me.” Hiroko rolled her eyes and took out a cigarette from her nightstand to smoke.

“Look… there’s still time. We can fix this” Aoi said, taking deep calming breaths. “I can run down to the pharmacy right now and get you some emergency contraceptives. I’ll even pay for it myself.”

“Hmmm… thanks for the offer, but no thanks. It might just be my biological clock ticking, but I’m actually down for having another kid; especially if they look as cute as Yuty over here.” Hiroko took a puff of smoke pinched Yuta on the cheek. “Don’t worry, if his wonder sperm really works, I promise I won’t hound him for support money. I’ll even convince my husband it’s his – trust me, he’s gullible.”

“Rrrgh… dammit, dammit, dammit!” Aoi stomped her foot hard on the ground and stormed out of the room, heading back to her apartment.

“W-wait, Aoi, hold on! Wait for me!” Yuta called out as he hastily threw on his clothes.

“Here’s that money I promised you, hun,” Hiroko spoke up as she handed the boy a stack of bills. “Plus a little extra for doing such a thorough job~ Oh, and good luck on working things out with your sister, by the way.”

“Thank you!” Yuta stuffed the money into his pocket and ran off after his sister, only to find her already locked inside her room. “Aoi! Aoi, please come out!”

“No!” Aoi shouted back through the door. “I’m not talking to you right now!”

“What? Why?” Yuta asked innocently. “Is something wrong?”

“Is something wrong?” Aoi got up and opened the door, revealing tears running down her angry face. “Of course something’s wrong! Don’t you realize what you just did?”

“B-but… everything worked out fine, didn’t it?” Yuta asked, fear and confusion in his voice. “Even if she is somehow pregnant, Hiroko won’t ask for child support, so we won’t have any more payments we have to make.”

“So!?” Aoi shouted angrily. “You still did the one thing I told you not to! You went out and probably knocked up another random woman, and a married one at that! What if her husband came home before I did? Or if he figures out you’re the father? At best, you just ruined that woman’s marriage; at worst, you could have gotten yourself killed!”

“I… I didn’t really think of that,” Yuta admitted, as somber expression cracking onto his face.

“No, of course you didn’t.” Aoi wiped her dripping nose on her sleeve. “I can’t believe how fucking selfish you can be sometimes.”

Yuta was about to say something else, but he couldn’t seem to find the words before Aoi slammed her door in his face. So he just stood there in silence for a few minutes before heading to his room, locking himself inside as well.

Aoi naturally didn’t go on that jog she promised her brother, instead just locking herself in her room trying her best to forget her troubles by hugging her pillow hard to her chest and reading her favorite books. However, as time ticked by, the fact that she skipped dinner came back to haunt her as her stomach grew more and more demanding. At around 9 PM, she finally gave into her hunger and quietly went outside to grab a donut from the kitchen, where she arrived just in time to see her brother head towards the front door dragging a loaded suitcase behind him.

“Oh, hey there, Aoi!” Yuta waved nervously and tried in vain to hide his suitcase behind his back. “Funny seeing you here…”

“Yuta? What are you doing?” Aoi asked with a concerned look on her face. “Are you going somewhere?”

“What? No, no, whatever gave you that idea? I was just, uh… taking out that trash is all!” Yuta put on his best and brightest smile to cover his guilt, but that only lasted a few seconds under the scrutiny of his sister’s glare. “Alright, you got me… I’m not taking out the trash, I’m… I’m moving out, Aoi.”

“Moving out?” Aoi gasped. “What do you mean? Why would you do that?”

“Isn’t it obvious, sis? I’ve been nothing but a burden to you.” Yuta’s shoulders slumped and her turned back towards the front door. “I’m just a selfish jerk who makes your life worse. You’ll be… better off without me.”

“… idiot.” Tearing up again, Aoi walked up behind her brother and pulled him into a sudden, hard hug. “Idiot, idiot, idiot!”

“Wha-!?” Yuta grunted in surprise and discomfort. “Aoi, what are you doing?”

“Isn’t it obvious? I’m not letting you go.” Despite the tears in her eyes, Aoi was smiling as she hugged her brother. “I know I get angry at you when you mess up, Yuta, but you’re my family. I love you more than anything else in the whole world, and I’ve never ever considered you a burden. Not even once.”

“Do you… mean that, Aoi?” Yuta asked, stunned.

“Of course I do, silly!” the swimmer replied. “Why do you think I was so angry earlier anyways? It’s because I was worried about you, of course!”

“Wow… thanks, Aoi. That means a lot to me.” The tan runner turned himself around in Aoi’s grip and hugged his sister back. “But… that doesn’t change how inconsiderate I’ve been. I need to do something to make up for that… and I think I know what I can do.”

Aoi’s eyes lit up. “Wait… do you mean…!?”

Yuta nodded and hugged her again. “I do. In fact, I’ll get it taken care of first thing in the morning!”

“Eeeee! Thank you, Yuta! Thank you!” Aoi squealed and hugged her brother so hard she picked him up off the ground.

“Aaaah… jeeze, that smarts…” Yuta groaned as he sat in a doctor’s office, a bag of ice on his groin. “I knew it would be sore afterwards, but I didn’t know it would be this bad.”

“Hehe, well, it could be worse! At least it’s not childbirth!” Aoi, wearing her jogging outfit, giggled as she held Yuta’s hand in the chair next to his. “I’m so proud of you, Yuta. You’ve finally taken responsibility for something! You’re really turning into a fine young man!”

“Alright, everything seems to be in order,” the doctor, a woman with long silver hair, said as she walked into the room. “You can leave whenever you want.”

“Really?” Yuta asked. “So… I can have sex with as many cute girls as I want now, and I won’t have to worry about getting them pregnant?”

“Yes sir!” she replied. “Until you come back and get that vasectomy reversed, the chances of you impregnating anyone is pretty close to zero.”

“Though, I’d still avoid sleeping with married women, if I were you,” Aoi was sure to add.

“Right, of course!” Yuta gently held the bag of ice to his groin and walked into the hallway, where he found a nurse with long black hair walking by. “Oh, hey there, miss! What’s your name?”

“Tch… I swear, that boy really can’t help himself…” Aoi said to herself. “… say, doctor. Why did you mention that his chances of impregnating a girl are close to zero?”

“Well… it’s hardly even worth mentioning, but… there is a slim chance that the vasectomy could end up reversing itself before he comes back. And if that happens, then he’ll be just as fertile as ever,” the doctor explained. “You don’t really need to worry about that, though. The chances of that happening are, like, one in a million.”
