Riku Soma pulled on his speedo, which was purple, just like his hair. Then he applied his sunblock, then picked up the tube of sunblock and headed out of his room and down the stairs. He went out the back door of his family's mansion and into the backyard, where the pool was, and placed the tube of sunblock on a table on the patio. It was a hot day in early summer, and Akademi's summer break had just started. He was particularly happy today because his girlfriend Kokona and her best friend Saki were coming over in about half an hour so that they could all go swimming together.

Kokona had just become Riku's girlfriend a couple of weeks ago. He had had a crush on Kokona for a little while, and with the encouragement of a couple of the other members of his school's Drama Club, which he and Kokona were both members of, he started hanging out and talking with her more frequently. Kokona gradually developed feelings for him during this time, and then eventually they confessed their feelings to each other under the cherry tree behind the school.

Not only was Riku an excellent boyfriend to Kokona, but he and his family also helped her and her father out of a sticky situation. Her father had taken a loan out from a particularly nasty loan shark who kept raising the interest rate every few days, which had put him into substantial debt. In order to try to pay off said debt, Kokona even had to step in and help, leading her to even do some things that she felt uncomfortable about, like compensated dating for instance.

But then when she explained her problems to Riku and his family, they were generous enough to step in and help pay off the debt, which they could easily afford to do given how wealthy they were. Kokona and her father could not be more grateful, and their families became friends from that point on.

Additionally, this also caused the bond between Riku and Kokona to grow even stronger, further strengthening and deepening what was already a very good boyfriend/girlfriend relationship. He couldn't help but smile fondly as he remembered the look on her face at the moment when his parents agreed to help out her father, and then again when she told him that it had been confirmed that her father's debts had been paid off (she had hugged and kissed him after that).

Currently, he continued to hang around outside, enjoying the summer heat, and anticipating the girls' arrival. He was excited, not simply because he would get to see them in bikinis as Kokona had promised him that they would wear (although that was admittedly a plus), but more importantly because he was really looking forward to swimming and spending quality fun time with them. Additionally, both of his parents were out of the house on business for a few days, and even their servants had the day off today and the following day, so they would have the house all to themselves.

He still had a little over twenty-five minutes before Kokona and Saki were due to show up. So he decided that he would do a bit of skinny dipping for a few minutes right now before they arrived. He didn't do skinny dipping very often, but on the occasions when he got the opportunity to do it, he always really enjoyed it.

But just as he grabbed onto his speedo to start pulling it down, the doorbell rang. A part of him was a bit disappointed, but he was also happy, because it meant that at least one of the girls had arrived (probably Saki, because Kokona would likely have just walked right in).

He entered the house and made his way towards the front door.

"Who is it?" he called out.

"It's me, Saki," called out Saki's voice.

He reached the door and opened it, and sure enough, Kokona's twintailed, cyan-haired best friend, Saki, was there, and she was holding a foil-wrapped plate of treats that she had obviously cooked.

"Hi Saki," he said with a warm smile.

"Hey Riku," she replied brightly with a smile, mixed with a small hint of surprise at seeing him in a speedo.

He glanced down at himself, and back up at her, and gave her a slight smile. "Do you like what you see?" he asked, slightly jokingly yet sincerely.

"Honestly, yes, it's nice, you like nice in it," said Saki sincerely. "And I bet Kokona will love it," she added with a slightly playful smile and a soft giggle.

Riku let out a small laugh and said, with a very slight and brief blush, "Yup, I bet she will."

He went on. "Anyway, come on in, Saki," she said, stepping aside to let her in the house. "You're here early," he added, as she stepped inside and he shut the door behind them.

"Yeah, I was able to leave earlier than I expected to," said Saki.

Before he could ask where Kokona was, she added, "Kokona is actually going to be a little late, by about ten or fifteen minutes. She had a few family matters to deal with, but she shouldn't be too long."

They headed back through the house together (Saki admiring how nice and lavish it was, and even commenting on it) and went out to the backyard together.

Saki placed her plate of treats on the same table out on the patio where Riku had placed his tube of sunblock. She took the foil wrapping off of the plate, revealing a plate of delicious-looking chocolate chip cookies.

She turned to him. "Do you want to try one?" she asked.

"Sure, I'd love to, thanks," said Riku.

"Go ahead, take one," she said with a sweet smile. "I baked them for us."

"Thanks," he said, picking up one of her cookies. "This is very nice of you."

She smiled sweetly in response as he tried the cookie.

"Wow," said Riku, impressed. "This is really good."

"Really?" said Saki.

"Yeah, I mean it," said Riku sincerely. "You're a really good cook. I know I've told you this before, but it's true."

Her face lit up as he said that, and she was a bit touched.

"Thanks," she said. "In fact, I can make treats like this for you more often."

"That would be nice, but you don't have to," said Riku.

"No it's okay, I'd love to, said Saki sweetly. "My treat."

Riku smiled at her. "Honestly, you're great," said Riku. "You're very sweet, and a great friend. You and Kokona are the best. You two truly deserve each other as best friends. I really mean it."

"Aw, thanks," said Saki, touched again.

Ever since he and Kokona started dating, the three of them had been hanging out together frequently. They all got along excellently, and Riku added a very pleasant and enjoyable dynamic to their little friend group. Additionally, he and Saki had really grown to like each other and were already starting to become good friends.

"Anyway, do you want to go put your swimsuit on?" asked Riku.

"Oh no need, I already have it on, under my clothes," said Saki. And with that, she removed her shoes, socks, skirt, and shirt, and stripped down to her bikini, which was cyan colored, just like her hair. She neatly folded up her garments and placed them on the table, and turned to face Riku.

Riku took a moment to admire her in her bikini, and her body - her curves, her thighs, her stomach, her breasts, and her overall slender figure.

His eyes lingered on her breasts for a brief moment. They weren't quite as big as Kokona's, but they were still quite large. Not wanting to stare too long, he then looked back up at her face. She was smiling, seeming a bit amused and a bit flattered (both of which she indeed was).

"Do you like what you see?" she she asked, playfully striking a slight pose.

He smiled. "Yes, I love it," he said sincerely. "You look great in that bikini. And you have a nice body. Seriously, I mean it, you really do."

She blushed slightly. "Thanks," she said.

She even checked him out a bit. Granted she had already had plenty of time to check him out since she had arrived, but she still did it again now anyway. "You look pretty good yourself, in that speedo," she said.

"Really?" said Riku.

She nodded.

"Thanks," he replied.

"I bet you look forward to seeing Kokona in her bikini," said Saki with a slightly playful smile, as she started to reapply her sunblock.

He laughed in reply (a genuine laugh), and blushed slightly.

"Yes, I do," he said honestly, and then added, slightly jokingly, "Of course I look forward to seeing my girlfriend in a bikini."

They shared a brief chuckle at that.

"And I bet the two of you would look excellent together, side-by-side," he added.

She chuckled again.

"I'm sorry she's late, but, you know," said Saki.

"It's alright, it couldn't be helped," said Riku.

She loved how he was being understanding.

"It's funny, she said, "she's late, and I'm so early."

"Yeah, I admit, I was a little surprised when you showed up early," said Riku. "In fact," he confessed, slightly bashfully, "I was going to go skinny dipping for a little bit right before you showed up. Sorry if that's a bit TMI."

He let out a soft chuckle. Saki laughed lightly in response, and Riku found her laugh rather sweet and musical.

"It's okay," she said. "I'm sorry I interrupted that," she added humorously, causing him to laugh a bit in response.

"Don't be," he replied. "You didn't know. Besides, I'm glad you're here. I get a little extra time to hang out with you."

"Aw, thanks," she said, a bit touched.

"Unless..." he said, "um..."

He paused, and glanced away from Saki a bit nervously, unsure if he should suggest what he wanted to suggest, and unsure of how she would react.

He let out sigh, and remained composed and forced himself to say it. "Would you like to go skinny dipping with me for a few minutes before Kokona arrives?"

He quickly yet firmly and calmly added, "I'm not trying to be creepy or a perv or anything, and you don't have to agree to it. I'm just throwing the idea out there."

He remained mostly mature and composed when explaining this, but he was clearly a bit nervous and flustered, and showed a few small signs of it (for example, he had blushed a bit at one point, and had a few slight eye moments that betrayed a bit of nervousness). Saki found this rather cute and adorable. She was indeed taken aback by his proposal, but she was not mad or creeped out at all, and knew that he had no bad intentions, and she took a moment to consider the offer.

Between Saki and Kokona, Saki generally tended to be the braver and bolder one. However, when it came to things like skinny dipping, and other things that started to push towards the more extreme and risque territory, Kokona was more likely to do or suggest something like that than Saki was. For example, Saki recalled one time when she and Kokona were walking through a park together one evening after school, and Kokona, with a slightly mischievous smile on her face, had suggested that they playfully shake their butts and flash their panties at some fellow classmates who happened to be nearby in the park; but she, Saki, had declined, visibly a bit flustered, which Kokona had found a bit amusing. Although nowadays Saki found the memory amusing.

She also recalled Kokona being willing to do things like selling her undergarments to raise money for the loan shark issue, while she, Saki, couldn't get herself to sell her bra, not even to help raise money for her best friend who desperately needed it. Granted, though, that situation was different, and had some real stakes given Kokona's father's situation, but still. And here, right now, she would just be casually swimming naked with her best friend's boyfriend just for fun.

Nonetheless, he wasn't pressuring her to do it, and she appreciated how honest and transparent he was being. And since she had gotten to know him, he had proven himself to be a good person, and very likable, charming, respectful, trustworthy.

So she decided she would accept his offer. It could even serve as sort of a reward to Riku for being a good person and friend. And she might be able to tease Kokona about it later (she smiled slightly at the thought). And who knew when she would get another offer to go skinny dipping, especially with a guy? There was a part of her that found the whole idea a bit alluring, and she figured it might be a nice and interesting experience, and it might bring her and Riku even closer together as friends.

She smiled at him and said, "You know what, sure, I'll go skinny dipping with you."

"Really? You will?" said Riku, slightly surprised, yet pleased.

"Yeah, let's do it," she said. And with that, she removed her bikini top, exposing her large breasts. She turned around, facing away from Riku, and placed the bikini top on the table, and then she pulled down her bikini bottom, exposing her butt to him. Kokona had slightly bigger breasts than Saki, but Saki had a slightly bigger butt.

After placing her bikini bottom on the table, she turned and faced Riku again, completely naked.

Riku, meanwhile, had been a bit taken aback by both her agreement to skinny dip and how quickly she had started removing her bikini, and had just stood there and watched, a bit stunned, as she stripped. Even when she turned to face him, fully nude, he still stood there, mesmerized, for a few seconds, taking in the sight of her nude body, and had still not pulled down his speedo at all. But then snapped out of his daze and quickly began removing his speedo.

"Sorry," he said.

"It's okay, don't worry about it," said Saki.

He pulled down his speedo and stepped out of it, and then they stood there for a little bit, looking at each other, and admiring each other's naked bodies. They were slightly nervous and their faces were a little warm, but they weren't feeling as nervous or awkward as they had feared they might. In fact, what little nervousness and awkwardness they did feel was starting to fade fairly quickly, and they were already starting to feel a bit more comfortable.

"Do you like what you see?" said Saki.

"Yes, I do," said Riku honestly.

"Yeah, I figured you did," said Saki blushing slightly with a slight smirk, gesturing to his groin.

Sure enough, he had a very slight erection. He blushed a bit, but remained composed.

Saki giggled lightly. "Don't worry about it, it's fine," she reassured him.

"Are you sure?" asked Riku.

"Yeah," said Saki honestly, nodding.

With that, Riku shrugged, feeling better.

"Do you like what you see?" he asked, gesturing to himself.

She smiled and nodded in response.

Then, with a burst of confidence, he turned around to let her see his backside, which she appreciated. After he turned back around to face her again, she did the same thing, turning around to let him see her backside.

"That's alright," said Riku. "I already got a look at your backside when you were taking off your bikini."

"Well, I'm giving you another look," said Saki, flashing him a smile over her shoulder.

He thought this seemed a bit unusually bold of Saki, but he appreciated it. He returned her smile, and then let himself have another good look at her naked backside, especially her butt, and let the sight sink in.

This was indeed a bit unusually bold of her, but the situation was sinking in a lot more, and they were both getting used to it more (Riku's slight erection even went away), and realizing it wasn't so bad, despite what society said. In fact, they were rather enjoying it. Not only was it admittedly a bit arousing, but more importantly it was a very nice and intimate bonding experience between these two friends. And overall, it made Saki feel a bit bolder.

"Alright," said Riku. "Let's go skinny dipping, then. We still have time before Kokona gets here. But let's bring our swimsuits with us and leave them at the edge of the pool in case she gets to the house early and we need to quickly put them back on."

"Alright, said Saki nodding, "but first I need to apply more sunblock to a few areas."

She applied some sunblock to her areas that were previously covered by her bikini, since they were now exposed to the sunlight. Riku, similarly, applied sunblock the area previously covered by his speedo.

Saki then grabbed her bikini off the table. "Alright, I'll race you to the pool," she said, with a playful smile, and immediately started running towards the pool, her twintails flying behind her as she ran.

Riku was slightly taken aback by this, but a split second later he had picked up his speedo off the ground and was running right behind her. Already he was rather enjoying this, chasing behind Saki and hearing her cheerful giggle at one point. At one point, Riku glanced down at her butt and thighs as she ran ahead of him.

When Saki reached the pool, she leaped off the edge, still holding her bikini in her hand. She lifted her legs up to her chest, hugged her knees, and landed in the water in a cannon ball style. Riku jumped into the pool right behind her in the exact same fashion. They came up broke the surface of the water, laughing together, and enjoying the feel of the cool water enveloping their naked bodies.

They swam over to the edge of the pool, where they placed their swimsuits right next to each other, and then started swimming and playing around together in the pool. It was an extremely pleasant experience for both of them. The water felt amazing on their nude bodies, and it felt a lot more comfortable and freeing without the added weight and constraint of any kind of swimwear. Very soon they no longer cared in the slightest about being naked together, and were instead very comfortable and relaxed. In fact, if anything, their nudity made the experience better. It made them feel a lot closer and more trusting, open, and relaxed towards each other, and deepened the bond of their friendship.

At one point they even played a brief game of Marco Polo, which ended with Riku finding Saki by accidentally touching her breast. But after the initial second of awkwardness passed, they both found it rather humorous and laughed, and it ended up being a funny and tender moment between the two friends. Also, he suspected that she let him touch her there on purpose, especially given the smirk that briefly crossed her face.

They kept swimming and playing around for a few minutes until they suddenly heard Kokona's voice calling from within the house. She had arrived earlier than Saki expected. Riku and Saki briefly exchanged looks that basically said "oh shit," and, knowing they had only seconds before Kokona walked through the house and out the back door and saw them naked in the the pool, they hurried to the edge of the pool where their swimsuits were and scrambled to put them back on. Saki had a little trouble getting her bikini top back on, and Riku helped her, and thankfully finished just as Kokona walked out the door and saw them.

"Hi Kokona!" called Riku, waving at her. Saki also called out and waved to her, and she and Riku got out of the pool together and hurried over to Kokona on the patio.

Kokona went up to Riku and they hugged each other, and then she reached up and kissed him, which he happily reciprocated. They stayed that way for a second before breaking apart. Saki watched them, a bit touched, and happy for them. She thought they were an incredibly cute couple and could tell what an incredibly good fit they were for each other.

Riku noticed that the front of Kokona's shirt and skirt were now damp from the water from his wet body.

"Oh don't worry, it's okay," she said. "Especially since I have my swimsuit on under here."

As she started to remove her shirt, she commented on Riku's choices of swimwear, which she indeed loved (Saki had certainly been right about that). He thanked her with a slight blush, and he and Kokona shared a sincere yet slightly humorous smile. By this time she had removed both her shirt and skirt, revealing her bikini, which was purple, just like her hair. She finally removed her shoes and socks and placed them on the table along with the rest of her and Saki's garments, and then she turned and faced Riku with a smile and slight blush.

"Well, do you like it?" she asked.

"Yes," he said sincerely, with a slight blush, "you look amazing. That bikini is perfect on you, and you have an amazing body."

"Really?" Kokona blushed and glanced away from him for a second, before looking back at him with a smile. "Well, thanks," she added, slightly bashfully, yet sincerely.

Saki grinned and suppressed a giggle, amused yet touched by their interaction and Kokona's bashfulness. Kokona stood there for a bit, letting Riku take in the sight of her in a bikini. As he did with Saki, he also admired her body itself - her thighs, her stomach, her large breasts, her curves, and her overall slender figure - except even more with Kokona since she was his girlfriend. Kokona, meanwhile, took in the sight of her boyfriend in a speedo.

"Hey Kokona," said Saki with a slightly playful grin, "why don't you turn around and let Riku see your backside? Especially your butt."

Kokona blushed a bit more, especially at the mention of her butt, but she did as Saki suggested. As with her front, Riku admired and absorbed the sight of her backside, especially her butt.

They couldn't help but notice how Saki was a bit bolder and Kokona a bit more bashful and nervous right now, since it was normally the other way around when it came to more "risque" or sexually charged situations. But this situation directly involved Kokona's boyfriend, so it made some sense that Kokona would be the less bold one here.

When Kokona turned back around to face Riku again, he turned around to give her a view of his backside, shooting her a sweet yet slightly playful grin over his shoulder. This made her blush a bit again, but by this time she had gotten a lot more comfortable and less bashful about this situation, and was even enjoying it at this point, so it didn't affect her as much. She complimented him on his speedo and his body (which was surprisingly well toned), which he greatly appreciated.

Once they were done checking each other out, Saki offered Kokona one of her cookies, and Kokona tried one.

"Wow," said Kokona after biting into it, "this is really good!"

Riku nodded in agreement. "Yeah," he said, "she is really good at cooking."

"Yeah, she is," said Kokona.

"Thanks," said Saki. "You two can have as many cookies as you want."

"Well aren't you going to eat some of them?" asked Riku.

"Yeah," said Saki, "but I made them mostly for you two."

"Well, thanks," said Kokona, "that was really nice of you."

"Yeah I know, right?" said Riku. "She's great. You're really lucky to have a best friend like her. She's really sweet, and caring, and an overall good person. Not to mention a good cook."

Kokona nodded in agreement to everything he said.

"And you two have the cutest friendship," he added.

Both Kokona and Saki smiled, touched by what he had just said, especially Saki.

"Aw, thanks," said Saki, and Kokona nodded in agreement.

They each ate one more of Saki's cookies, and then Riku suggested they all finally go swimming.

"Absolutely!" said Kokona brightly, and they all started walking to the pool.

But a couple seconds later, Saki stopped walking and said, hesitantly, "Well, actually..."

Riku and Kokona stopped talking and turned to her. Saki hesitated, wanting to suggest what she was about to, but unsure if Riku would be fine with her suggesting it. But she got up the courage and decided to suggest it anyway.

"We could go skinny dipping," said Saki.

"What?!" said Kokona, her eyes widening slightly, clearly taken aback. Riku suppressed an amused giggle at her reaction.

Saki looked at Riku, silently asking him via her facial expression if she could tell Kokona about them skinny dipping earlier.

"Well, alright," said Riku. "You can tell her."

"Tell me what?" asked Kokona, her eyebrow slightly raised.

"Well," began Saki, slightly bashfully. "Before you got here, Riku and I went skinny dipping for a few minutes," she confessed.

she turned to Riku. "Is this true, did you really?" she asked.

He nodded, blushing slightly, but then he and Saki smiled.

"Well," said Kokona, "I guess that explains why you two were right next to each other in the pool and seemed to be scrambling to do something when I came out here and saw you."

Riku and Saki blushed slightly for a second, nodding.

"Yeah," said Saki, "and it was actually pretty fun, skinny dipping."

"Yeah, it was great," said Riku honestly.

"A lot better and more freeing than with swimsuits," said Saki.

Riku nodded in agreement.

Saki, with a slightly playful smile, said, "And he touched my breast."

Riku shot Saki a slightly angry and panicked look for a brief second as Kokona looked sharply between the two of them, and then he very quickly composed himself and clarified, firmly, "accidentally while playing Marco Polo."

Saki chuckled slightly, but then said, "Yes, exactly."

This calmed Kokona down. She couldn't help but feel a little jealous, but she had figured from the beginning that it was a simple, sweet, funny, innocuous moment between friends, and nothing more, and now she fully understood it. And that was one of the things that Riku loved about Kokona. She tended to be understanding, rather than blowing things needlessly out of proportion.

"Also, you played Marco Polo without me?" Kokona added with a slightly playful grin. This caused all of them to laugh. Riku had never played Marco Polo with Kokona before, but she had told him that she loved that game, and Saki confirmed it (in fact she had played it with Kokona herself before).

"So how about it, Koki?" asked Saki. "Do you want to go skinny dipping with us?"

"We don't want to pressure you, though," said Riku. "We don't have to do this if you don't want to."

Kokona thought about it, and then after a few moments she decided she would go along with it, coming to more or less the same conclusion that Saki had when she initially considered it. Additionally, there was the fact that Saki, who was generally less likely than Kokona to try things like skinny dipping, had done it and clearly enjoyed it (and had become a bit bolder than even Kokona at a few moments regarding things where Kokona would normally be the bolder one), and that gave Kokona even more encouragement to try it herself.

"Alright," said Kokona. "I'll give it a try. I'll go skinny dipping with you two."

"Great!" said Saki brightly. "Don't worry, it'll be fun!"

"Yeah," said Kokona, "although it's a shame that I won't get to put my new bikini to good use."

"Oh it's not the end of the world," said Riku reassuringly. "You can use it another time."

"And you did put it to good use by looking amazing in it," said Saki.

Riku nodded and smiled in agreement.

"Thanks," said Kokona, "you look great yourself in yours, Saki."

"Aw, thanks," said Saki sincerely, and she and Kokona shared a sweet and sincere smile.

Riku watched the interaction between them and smiled himself. "You two really are the best," he said. They smiled sweetly at him in thanks.

"Alright, let's do it," said Saki. And with that, she started removing her bikini, and Riku started removing his speedo. Kokona hesitated for a moment, and then started removing her own bikini. After removing it, she stood there, completely naked. Riku and Saki stood there completely naked as well, and they (especially Riku) looked at Kokona and took in the sight of Kokona's naked body, and she took in the sight of Riku and Saki's naked bodies (especially Riku's).

Saki then suggested, with a slightly playful smile, that Kokona turn around and show her backside. Kokona blushed slightly and did so, and the other two admired and took in the sight. After she turned back around to face them, they turned around and showed her their backsides, and Kokona took in the sight.

By the time Saki and Riku turned back around to face Kokona, Kokona had started to become comfortable and relaxed being naked with Riku and Saki. Once again, Riku suggested that they all take their swimwear with them and place it at the edge of the pool, in case, say, his parents showed up. They all chuckled a bit, since they knew it almost certainly wasn't going to happen, but then again, it was better to be safe than sorry, so they agreed, and they all picked up their swimwear off the table.

"Alright, let's get swimming," said Riku.

"Yeah," said Saki, "but Kokona, you should first apply some additional sunblock since certain, well, areas are no longer covered by a bikini."

"Oh, right, good point," said Kokona, blushing slightly, and she applied some sunblock to her areas that were previously covered by her bikini.

"Alright," said Saki excitedly, once Kokona was done. "I'll race you both to the pool." And just like before, she took off running towards the pool. Kokona and Riku took off after her a split second later.

They all ran to the pool together, Saki in the lead, followed by Kokona, and finally Riku bringing up the rear. Once they reached the pool, they all leaped in cannonball-style, just as Riku and Saki had done the first time.

After placing their swimsuits next to each other on the edge of the pool, they all started swimming around and having fun. Riku and Saki had been right, Kokona quickly discovered. It was an incredibly freeing and comfortable experience without the constraint of any kind of swimwear, and the cool water felt incredible on her nude body in contrast to the summer heat. Very soon she no longer cared in the slightest about being naked with Riku and Saki, and instead found herself very comfortable and relaxed, just like Riku and Saki did.

They even played a few games of Marco Polo, which, yes, resulted in a little touching at times, including boob touching. But just like with Saki and Riku's little incident, it all ended up being not awkward, but rather fun, tender, and humorous.

Overall, the skinny dipping was an incredibly pleasant experience for all of them, and one that they would always treasure and never forget. Just like with Riku and Saki's initial experience together, their nudity made the experience better for the three of them. It made them feel a lot closer and more trusting, open, and relaxed towards each other, and further deepened their bond and brought them closer together as friends.

A couple hours later, the three friends had gotten out of the pool, but stayed naked, and they were now currently sunbathing naked together, side-by-side, on fully-reclined pool chairs.

During this time, they realized that they had to reapply their sunblock. Riku got up and ran over to the patio, grabbed the tube of sunblock from the table, and ran back to the girls at the pool chairs. But then he offered to the girls to help reapply their sunblock for them.

To his surprise, not only did Saki and Kokona agree to it, but they agreed to let him reapply it to their entire bodies (yes, their ENTIRE bodies), as suggested (slightly playfully and mischievously, yet sincerely at the same time) by Saki.

Riku decided to start with Kokona, and he knelt down next to her as she sat up on her pool chair.

"Hey Riku," said Saki, "you're really lucky, getting a chance to completely feel up your naked girlfriend. And Kokona you're lucky to be felt up while naked by your naked boyfriend."

Saki said this with a playful yet sincere grin. Riku and Kokona blushed a bit, and Riku raised an eyebrow at Saki, but he also chuckled a bit, amused. And he and Kokona couldn't even deny what Saki said, because it was true.

"Alright, Kokona," said Riku, squeezing out a bit of sunblock into the palm of his hand, "where would you like me to start?"

"Let's start with my legs and feet," said Kokona.

Riku nodded, and gently started applying the lotion, starting with her thigh. While he did this, he noticed and admired how soft her skin was, and really enjoyed and savored the feeling. She, meanwhile, really enjoyed and savored his gentle touch. He continued rubbing the sunblock all over her thighs, her calves, and her feet, all the while taking in the feeling of her skin and the curves of her body, and with her enjoying the sensation as well.

Although, when it came to her inner thighs, he didn't go all the way up. But then Kokona surprised him by saying that he could go all the way up her thigh if he wanted.

"Really?" said Riku, blushing slightly.

Kokona was blushing as well, but smiling sincerely as she nodded and said, "Yes, go ahead." And then after a moment she added, "in fact, you..." - she glanced nervously to the side for a bit, then turned her eyes back to him - "...you can also put sunblock on my...my vagina."

Both Riku and Saki were taken aback by this, so much so that Riku almost (but not quite) lost his composure.

"A-are you sure?" he asked.

"Yes, it's fine," she said, blushing a bit, but also a bit amused by his slight stutter.

"I don't want to if you're not comfortable with it," he said.

"No really, it's fine, please do it," she said honestly, and she spread her legs a bit, and had a slight hint of excitement in her smile. (Although she and Saki did admire and appreciate how considerate he was being.)

"Besides," added Kokona with a hint of playfulness, "I don't want to get sunburned down there."

Both Riku and Saki couldn't help but crack an amused smile at this.

She was blushing a bit harder now, but she was still smiling sincerely at him and retaining her composure. He returned her smile and resumed applying the sunblock, and finished applying it all the way up her inner thighs. Out of the corner of his eye, he could've sworn he saw Kokona shoot a brief slight smirk at Saki.

He then squeezed a bit more sunblock out of the tube and onto his hand, took a deep breath, and started rubbing the sunblock onto her vagina. She gasped in pleasure as he touched the sensitive and intimate area.

"Do you want me to stop?" said Riku, pulling his hand away.

"No!" said Kokona sharply, grabbing his hand and putting it back onto her vagina.

Her expression then softened, and, blushing a bit, she said, "Please keep going."

He did as she asked and continued rubbing sunblock onto her vagina. He was actually touching his girlfriend's vagina (for the first time), and he was nervous but also happy and excited, as was she. This was a memory that neither of them would ever forget. She moaned as he touched her, which turned him on even more, and, unsurprisingly, they were both blushing. But they remained composed all throughout. Oddly it wasn't as awkward as one might have expected it to be.

In fact, they enjoyed it, and they were quickly getting more comfortable with it.

He glanced up at her, and they looked lovingly into each other's eyes, and they could tell that their bond had deepened even further, and even Saki could tell this by watching.

Saki watched them, amused, but also touched by the sweet and tender moment being shared between the two lovebirds. She couldn't help but let out a small giggle. This giggle, however, did finally snap Riku and Kokona out of their distracted moment, making him realize that he had spent way more time on her vagina than he needed too. So he stopped rubbing it, to his and Kokona's slight disappointment, and they moved on to finish the task at hand.

Kokona turned over and laid on her stomach, and Riku proceeded to apply sunblock to her neck and shoulders. They had another sweet little intimate moment as he rubbed sunblock on her shoulders and it turned into a massage, but it was very brief, much shorter than their previous intimate moment.

He then did her arms (he earned a few small ticklish giggles from her as he did her armpits), and then her back, being gentle and soothing the whole time. He then moved on to her butt. Here he too spent a slight bit more time than he truly needed to, savoring the feeling of the soft cheeks. But, like with her shoulders, he didn't spend too much extra time, here, and he elicited a few pleasured moans from Kokona, who was also enjoying it.

She then turned back over and sat up again, and he did her face. He then moved on to her stomach (with a little ticklish moment with her belly button), and finally, her breasts. As one might guess, yes, they had another slightly overlong (but again, not too long) intimate moment. She relished in the feeling of his gentle touch on her breasts, and he savored the moment as well, admiring and taking in how soft yet firm they were. Also, by this time, they were both a lot more comfortable with this whole thing.

He finished with Kokona and then moved on to Saki. As he approached Saki's pool chair, she smiled at him and turned over to lay on her stomach.

"You can start with my backside," she said.

Riku smiled back and started applying sunblock to her shoulders, her arms, her back, her butt, the backs and sides of her legs, and her feet. As he did with Kokona, he savored the feeling of her curves and soft skin, but he spent less time and got less distracted this time and remained well focused all throughout (although he and Kokona could've sworn they saw Saki give a slight pout at this fact, even though she was clearly still enjoying it overall).

By now, they were all less nervous and more comfortable and relaxed with this situation, and even enjoying it. And, having already applied sunblock to one naked girl's entire body, he found it a lot easier doing it to Saki this time (combined with the fact that Saki was just a friend and not his girlfriend). Kokona was understandably a bit jealous while he did all of this, but she was still very understanding, and was happy that they were enjoying it.

Saki said that he could go all the way up to the tops of her thighs, as he did with Kokona, but he said that he would do that while he was doing her front afterwards. She agreed, and gave him permission to do her vagina as well, if Kokona was okay with that. After a moment of hesitation, Kokona approved.

After he finished with Saki's backside, she flipped over and sat up, and he did her face, her neck, her stomach, and her breasts. When it came time to do the fronts of her legs and the top portion of her inner thighs, followed by her vagina, she preemptively spread her legs to make it easier for him, and she gave him a slightly playful smile as she did so.

"What's gotten into you today?" Kokona said to Saki.

"What do you mean?" said Saki, smirking at her.

"You're being quite bold, and naughty," said Kokona.

"Well, I do tend to be the bolder and braver one of the two of us," retorted Saki.

"Not for stuff like this, though," said Kokona. "What happened to the Saki who wouldn't flash her panties at some people in the park?"

Saki shrugged and smiled and said, "What can I say?"

Indeed, this whole experience seemed to have awakened something inside Saki, and made her even braver and bolder concerning things like nudity, skinny dipping, etc, and even a bit of naughtiness.

Riku applied the sunblock to her upper inner thighs. When it came time to do her vagina, he and Saki glanced over at Kokona for one more bit of final approval, which she silently granted with a nod of her head. He applied sunblock to Saki's vagina, although he didn't spend nearly as much time on it as he did with Kokona's vagina.

"You're finished with that already?" said Saki with a slightly playful pout as he finished.

Riku smiled and shrugged. "What can I say?" he said. "I guess I was more focused on the task at hand this time."

"Plus," said Kokona, "I'm his girlfriend, so he loves me more, and spent more time with me on that spot."

Riku chuckled, and said, "Yeah, that too."

Kokona laughed along with Riku, and then Saki joined in.

Now that Riku had finished reapplying sunblock on Kokona and Saki's bodies, they both then proceeded to reapply sunblock on his body in return. Yes, his entire body, including his you-know-what.

After they were done, they resumed relaxing and sunbathing naked on their reclined pool chairs, occasionally shooting warm, sincere smiles at each other, and basking in the summer heat and the warmth of their friendship.

At one point later on, Kokona and Saki undid their hairdos and let their hair down, and Riku got a chance to admire them both with their hair down. They then played around with each other's hair and did a few different things with each other's hairstyles. Riku watched them, interested and entertained, as they did this, and he even learned a few things about hairstyles and how to put up their hair as he watched them. And they eventually let him join in and play around with their hair too, which he really enjoyed. They all had fun and shared a lot of laughs during this time.

Finally it came time to put their hair back the way it was, to their usual hairstyles - Kokona with her twin drills, and Saki with her big Miku-like twintails.

"Are you sure you want your hair exactly the same?" he asked Saki as she was putting her hairstyle back to normal. "You don't want to change your hairstyle yet again?"

This made Saki and Kokona both laugh, and Riku joined in, as they all thought about how many times Saki had changed her preferred hairstyle over time.

Later on, in the early evening, they all bathed together (a very pleasant and relaxing experience, and with a few humorous moments, including one moment where Saki playfully sprayed water at Kokona's face, eliciting an amusing squeal from her).

Then they all had a pleasant dinner together, cooked by Saki. She had insisted on cooking for them, and the meal she cooked was delicious. The view of the gorgeous sunset out the window made their dining experience even better.

After they finished dinner, it was time for Kokona and Saki to leave. They wished that they could spend the night, but they doubted that any of their parents would approve of it, at least at the present time. Maybe over time they could convince them and prove that they could be trusted, but for now they had to make do with Kokona and Saki leaving for the night. They already planned on meeting up the next day as well, and so they looked forward to that.

They all put their clothes back on, and then Riku walked Kokona and Saki to the front door. He hugged and kissed Kokona, and then he hugged Saki and gave her a slightly playful kiss on the cheek, which made her giggle (her giggle was rather sweet and musical). Kokona couldn't help but feel a slight twinge of jealousy, but again, she was understanding, and found the moment amusing, and was happy for Saki. As Kokona and Saki walked out the door, he smiled and waved goodbye at them, and they smiled and waved back as they walked away from the house.

This day had brought them all closer together and had deepened their bond, and they were eagerly looking forward to meeting up again the next day.

And for the record, yes, Kokona and Riku eventually got married and spent the rest of their lives together. And Saki remained best friends with them the whole time as well.
