Fan Fiction Sex Story: Chapter 18 - Hiro may be the youngest person to ever attend SFIT, but that doesn’t mean he’s too young to handle the various challenges that come with college life, including love. But what will he do when that particular challenge comes from several different sources at the same time? (Updated twice a month)

Despite the intense night the teens had, they and everyone else still woke up with plenty of time to get to the airport for their nine AM departure. Oddly, since they had a direct flight to their destination thanks to the Frederickson’s private jet (piloted by Fred’s butler, Heathcliff, of course) and because of time zone changes, they would actually land on the island earlier than when they took off, which was great as it would maximize the amount of daylight for that first day. The reverse would happen when they went home but they could simply leave at night, even though that meant losing out on some sleep upon their return.
They were only in the air for a few minutes before Hiro called everyone to attention. “First of all, I’d like to thank all of you for being able to come. It’s great to finally go on vacation with you guys. And thank you Fred, for funding it.”
“Hey, what’s the point of being insanely rich if you can’t treat your friends every now and then?” Fred said. “Besides, it’s about time we get our obligatory beach episode.”
“Obligatory beach ... what?” GoGo asked, slightly confused.
“Obligatory beach episode. It’s a very popular trope in anime. One episode has the main character and their friends all hanging out at the beach or pool, to have a break from the main story and so the audience can have some eye candy. If we were a TV show this would be our beach episode, though since we’ll be there for a whole week it might actually be a multi-episode arc.”
“ ... Okay,” GoGo said slowly, understanding what Fred was saying but not really wanting to think about it further. “Though considering where we’re going I don’t think it would be suitable to air on TV.”
“Not on the kids channels,” Fred said, grinning.
“Anyway, I still want to say thanks for paying,” Hiro said. “Getting back to what I was saying before, now that we’re airborne I have a bit of a confession. And a request. No, the plans for the resort haven’t changed or anything like that but, um, if you don’t mind, there might be some slight reworkings of the sleeping arrangements.”
“What, you don’t want to be my roommate anymore?” Wasabi said, pretending to be hurt.
“No offence, Wasabi, but I’d much rather room with my girlfriends.”
“Hold up! Did you just say girlfriends? Like, with an ‘s’?” Wasabi said, looking back and forth between Hiro, Karmi, and Megan in shock.
Hiro nodded, blushing. “I mentioned a confession. You all know that I’m dating Karmi. What you may not know is that I’m also dating Megan.”
“OMG!” Fred shouted, understanding hitting him like a brick wall. “So it wasn’t Megiro or Karmiro, but Karmirogan? Dude! That’s awesome!”
“We weren’t trying to hide it or anything,” Megan said, blushing slightly as she got up and stood next to Hiro, taking hold of his hand, “but my dad would definitely not be happy to learn that I’m, um, sleeping with someone. Especially since that someone is also sleeping with someone else.”
Karmi came up to Hiro’s other side and held his free hand. “So we’d really appreciate it if you would keep the fact that Megan is part of our relationship to yourselves.”
“Of course!” Olivia said, giving the three teens a huge smile. “A person’s sex life is even more sacred than a superhero’s secret identity, so we definitely won’t blab!”
Hiro thought that a little funny, considering that Olivia seemed to be more than happy to put her own sex life on display, to those present at least. “Baymax knew about us pretty much from day one, and we ended up telling Honey Lemon and GoGo last night,” he continued. “We didn’t want to hide or pretend we weren’t together while on vacation, so we agreed to tell the rest of you as soon as we could.”
“Since we’re sharing some pretty intimate secrets, you should all know that GoGo and I are lovers,” Honey Lemon suddenly said. “Have been for a while now.”
That got several raised eyebrows from those who weren’t in the know. GoGo rolled her eyes. “Oh come on. Don’t act so surprised. Why do you think we had our room changed from two beds to one?”
“We’re surprised because we’ve only ever seen you show interest in guys,” Wasabi said.
“That was before GoGo and I, um, hooked up,” Honey Lemon said. “Turns out neither of us was as straight as we thought we were.”
“Well you already know about Olivia and my adventures in the simulator, so I don’t think there’s anything new for us to confess,” Fred added.
“What about you, Wasabi? Any updates on your love life?” GoGo asked.
“Nope, still single and NOT ready to mingle,” he said, relaxing in one of the nice lounge chairs that were available.
“Aww, why not?” Honey Lemon asked.
“Are you kidding me? Do you have any idea how many germs-”
“Are in the human mouth,” GoGo interrupted. “Yes, we are all well aware. But the last time you tried dating was before we became heroes. The rush of adrenaline you got from that helped you get past your timidity, at least while the adrenaline was flowing. Maybe that can help you get past your phobia as well.”
“So what, I need to be in a fight for my life in order to kiss someone?”
“No, that’s not what I’m saying. I’m sure you could find some other way to get your heart pumping like crazy that doesn’t involve actual danger. I’m willing to bet that there will be plenty of ladies at the resort that would love to spend the night with a tall, dark, strong, and handsome guy like you. And maybe once you get your dick wet you’ll understand that the exchange of bodily fluids is totally worth it.” Her comment made Wasabi blush, though with his dark complexion it was almost impossible to tell.
With those announcements over, they broke into smaller groups for more conversations. The guys, including Baymax, all gathered together to grill Hiro on how he managed to pull off a feat many men dream of but few achieve, and if there have been any conflicts or jealousy between the two girls.
Olivia was the first to snag Karmi and Megan for their inevitable questioning, though Honey Lemon and GoGo had plenty of things they wanted to ask as well. “So I hope you don’t mind me asking, but is your relationship with Hiro Poly-V or more like a Triad?” she asked.
Karmi and Megan looked at each other to see if they knew what Olivia was talking about, but each was just as clueless as the other. “Um, sorry, but we’re still kind of new to the whole polyamory thing,” Karmi said. “We have no idea what those terms mean.”
“Oh, um...” Olivia quickly looked around and found a pen and paper. She drew the letter V, labelling the top ends with the girls’ names, and the bottom corner with Hiro’s name. “Poly-V is like this. You and Hiro are lovers,” she said, looking at Karmi and pointing at the line that joined their names. “And you and Hiro are lovers,” she said, doing the same for Megan. “But that’s as far as things go. A Triad, though,” she said, drawing a line across the top of the V, turning it into a triangle.
Both girls understood immediately and blushed deeply. “Oh! No, we’re not ... Megan and I have never...” Karmi stammered.
“Definitely Poly-V,” Megan added, unable to look at Karmi as she spoke. “We have been with Hiro at the same time. Come to think of it, that’s kind of our default but Karmi and I have never done anything with each other. Well, we have held hands a couple of times while Hiro was, you know, but I’m sure that’s not what you’re talking about.”
“That’s too bad,” Olivia said. “There’s so much more that three people can do when they’re all lovers, rather than it being two overlapping pairs.”
“And you know this from experience?” Karmi asked. Her tone was rhetorical, but that was to mask the genuine curiosity she was too embarrassed to admit having about the subject.
It was Olivia’s turn to blush this time, though hers was much milder compared to the teens. “Sort of. Fred and I got a taste of it in the simulator using one of the robots as our third. It was fun, but even if the bot looked real it didn’t feel real, you know? Hard light and plastic are not the same as flesh and blood. You guys technically have more experience in that department than us so if you have any pointers, I’m all ears,” she added with a grin.
The rest of the flight wasn’t nearly as exciting as that initial revelation, though Hiro, Karmi, and Megan still had to spend most of the journey answering questions or listening to unsolicited advice from their friends. It was all in genuine concern and good faith, though, so they couldn’t really complain. It was actually rather touching how accepting and supportive their friends were of their rather unconventional relationship.
When they landed, Heathcliff helped unload their luggage and then began the prep work to take off again. “You’re not sticking around, Heathcliff?” Hiro asked. He was so used to the Frederickson’s butler going wherever Fred did that he had just assumed that the man would be staying as well.
“No,” the elderly gentleman said with his posh British accent. “My primary responsibility is to take care of the family manor. To spend an entire week simply accompanying Master Frederick in a place where his needs and wants will already be taken care of would be negligent to that duty. Besides, this vacation is for you and your friends. My presence would only interfere in whatever activities you may have planned.”
“I don’t know of any particular activities,” Hiro replied. “We’re just going to hang out and have fun.”
“Yes, and your idea of ‘fun’ will no doubt be radically different from my own.” Heathcliff said, checking off the last item on his safety list before climbing back in to fly home. “May you and your friends enjoy yourselves to the fullest, Master Hiro. I shall return to pick you up in a week’s time.”
Those staying all waved goodbye as they made their way off the tarmac and boarded a waiting shuttle that would take them straight to the resort’s main desk.
“Ah! Mr. Frederickson! The man behind the desk said as they entered. He was very well dressed and looked to be in his late twenties, maybe early thirties. “We’re delighted to have you back with us once again!”
“Jimmy!” Fred said and held up his hand in a fist. The other man, James according to his name tag, responded in kind and the two of them performed a rather elaborate handshake. Clearly they’d done this ritual greeting before. “How many times do I have to tell you to call me Fred?”
“The same number of times I have to tell you that it isn’t proper to refer to our employer’s son in so casual a manner,” James responded with a smile.
“Bah, whatever,” Fred said dismissively. “So do you have everything ready for us?”
“Indeed we do, sir. You and your friends are the only guests we are expecting to arrive today so please allow me to personally show you to your rooms. It is my understanding that this is the first time any of you other than Mr. Frederickson have come to our resort, so if you have any questions please do not hesitate to ask.”
“Will do,” Wasabi said as James led the group over to an elevator. “To start, what is your procedure for sanitation?”
James answered Wasabi’s questions all the way to their rooms, which really wasn’t all that far, but hearing the answers from a staff member greatly reduced Wasabi’s worries. He was also very happy to learn that since the dining area was a shared space for all guests, it was not clothing optional. All staff and guests were required to be properly covered while eating there.
“I have a question,” Hiro asked after that piece of information came out. “You included staff in the part about being dressed in the dining room. Does that mean that they can go undressed in the areas that allow it?”
“Indeed they can, sir,” James answered. “In fact, we are encouraged to lead by example, so in the clothing optional areas you will find staff members unclothed far more often than clothed. If you intend to spend any significant amount of time there, then there’s a good chance you’ll get to see me naked before your vacation is over.”
“Without clothes, how can we tell the staff apart from the guests?” Megan asked. It took her a second to realise that her question was a tacit admission that she was at least thinking about going over to that side, making her blush slightly. The others noticed her reaction but didn’t react themselves with anything more than a slight grin.
“By this,” James said, holding out his wrist. On it was a rather fancy looking white wristwatch. “Only employees have this device. It’s not just a watch, but a communications device, allowing us to get in touch with any area of the resort. And it has a built-in holoprojector with a map of the island, for quick and easy navigation,” he added, and demonstrated that particular feature for them. With the push of a button, a translucent miniature of the entire island appeared above the watch.
“We are here,” he said, zooming in on a little red dot inside the main building. “And the mapping software can instantly find you the most direct path to wherever you want to go. There’s the dining room, the gymnasium, indoor pool, outdoor pool, outdoor pool on the clothing optional side, and here are a few of our more popular beaches.” For each destination, he brought his finger to that location on the hologram and a line instantly appeared showing them how to get there. “This last beach has sort of become the unofficial hub of, shall we say, extreme public displays of affection. So depending on how comfortable you are with such activity I would recommend you check it out, or keep your distance. If you hear anyone talking about ‘The Other Beach’, that’s the one they’re talking about.”
“So just to be clear, public sex is actually allowed?” Olivia asked.
James nodded. “It is, with certain conditions. One of the perks of being a privately owned island in international waters is that technically, we’re our own country, complete with our own laws. Though out of respect for those who do not want to see such activity and for the protection of children, we respectfully ask that any explicit activity be done either in private or at that particular location, as that is the only location on the island where children are discouraged from going.”
“And what makes one a child?” Karmi asked. “I’m only seventeen so I am not legally an adult.”
“Not legally an adult in America,” James pointed out. “Here, teenagers have all the same rights and freedoms that adults do. So you, as well as young Mr. Hamada and Miss Cruz,” he added with a nod to the two of them, “have no restrictions on where you can go or what you can do.”
“Or who,” GoGo added in a stage whisper, making the three teens blush.
Wasabi had a few more questions, so while James answered him the others began settling into their rooms, with plans for them to all go swimming once they were unpacked. Hiro gave Baymax the choice of where his charging unit would be set up, and Baymax opted to stay in Wasabi’s room in order to give Hiro, Karmi, and Megan more privacy.
The rooms were quite luxurious, as one might expect from such a high-end resort. They weren’t just a bedroom, but also had a large lounge area with several comfy chairs and couches surrounding 3 sides of a coffee table with a large wall mounted TV on the other side. The bedroom portion had two full sized beds, since that was what Fred was told when they booked things, but all three teens knew that one of those beds would likely not be used much, if at all. The beds were easily large enough for two, though they’d have to get pretty close to make all three of them fit, not that any of them minded that.
It was both thrilling and a bit embarrassing for Hiro as he unpacked, knowing that he would be spending an entire week living with two girls almost as if it were a honeymoon. But now that all their friends knew of and accepted their relationship, for the first time the three of them could express their love openly without the worry of being caught or told to end their relationship.
“So, uh, do you want to try out the bed now, or...” Hiro teased as he joined his girlfriends in unpacking his suitcase.
“Down, you horndog,” Karmi said, playfully swatting his arm. “We’ll have plenty of time for that later. The others will be waiting for us and I for one can’t wait to see what a tropical beach is like.”
“Which beach?” Megan asked with a grin. “One where you have to wear a bathing suit, or one where you don’t?”
As much as the three of them had teased each other in the lead up to actually going on this trip, now that it was very much a reality none of them actually felt brave enough to jump straight to being naked in public. They finished moving their clothes into the provided dressers and closet, then quickly changed into bathing suits and applied a liberal amount of sunscreen all over each other. It definitely would not do to get a sunburn on their very first day here. Megan also used the opportunity to call her dad for the promised daily check in to let him know they arrived safe and sound and were currently settling into their rooms.
When they were just about done, a knock came at their door. “Hey you three,” GoGo called from the other side of the door. “You ready yet?”
“Yeah, we’ll be out in just a sec!” Megan called back. More quietly she asked, “So what are the odds that at least Fred will already be naked?”
“I’d say eighty-twenty,” Hiro answered, knowing how open Fred and Olivia were to letting others see them without clothes.
“No, it’s fifty-fifty at best,” Karmi disagreed. “We never discussed where we would be going first so they’d want to keep the options open. With bathing suits you can go anywhere. Without them you can only go to some places.”
“Good point,” Hiro conceded. “Let’s find out, shall we?”
Opening the door, the three of them held their collective breath and a moment later let it out in relief when they saw everyone else in the hall waiting for them, all wearing bathing suits, even Baymax. They couldn’t help but chuckle when they saw him.
“Where did you get those?” Hiro asked with a laugh. “I don’t remember packing anything like that.”
“Fred acquired them for me,” Baymax answered. “He said that since I am technically naked when not wearing my armor, that I should have something when in areas that require clothing.”
“I don’t think the clothing rules apply to you, Buddy, but they do look good on you.”
“Alright, enough talking,” Fred declared. “Let’s hit the beach!”
With a collective cheer, everyone followed Fred as he led them out the resort and into the bright mid-morning sun.
The beach they went to was quite spectacular. Bright, pale yellow sand, warm blue-green water, palm trees for shade, areas set up for beach volleyball, and a nearby rustic looking hut where people could sit down in the shade and order food and drink, all together made it a very idyllic location. The first thing they did was claim a spot on the beach to leave their towels and other things, then the teens and Fred all raced to be the first in the water. The others followed, but not as quickly or enthusiastically as the other four. They all swam, floated, and played with a beachball all the way to lunch, where they ordered some wonderful and very fresh seafood from the nearby food hut, then once their food was settled, had a fun game of beach volleyball.
WIth nine humans and one robot they made two teams of four each, with the remaining two as spares so they could rotate on and off as needed. Wasabi and GoGo were both quite skilled players, while Karmi and Megan were fairly decent, though the others were only barely competent enough to keep the ball in the air. Had Baymax been programmed with volleyball skills he could have dominated everyone, but instead he was barely able to get under the ball in time to keep the play alive. Still, they had fun and to reduce any one-sidedness they all switched sides whenever they rotated back on.
Not just Hiro, but Fred and even Wasabi, had a hard time keeping their attention on the game, especially with the way the girls’ various bits bounced and jiggled while playing. The guys weren’t the only ones staring, either, as the girls on more than one occasion were called out by one of the others for getting distracted by the boys’ bare chests and toned muscles. Everyone was teased at least once for letting their eyes wander, but it was all in good fun and those whose partner was being ogled took it for what it was, an appreciation of the opposite sex and nothing more.
Once they all had their fill of volleyball they splintered off into smaller groups, mostly by relationship status, to either lounge around on some very comfy beach chairs, go for a walk along the beach, or have another dip in the ocean. Hiro was mercilessly teased by Karmi and Megan about him wishing they were on the other side of the island so he could see Honey Lemon, GoGo, and Olivia without their bikinis. He didn’t bother denying it and instead teased back about how they couldn’t keep their eyes off of Wasabi and Fred and doubtless were wondering about them the same way he was about the women.
When dinner time arrived they all headed back to their rooms to shower and get dressed in something nice so they could all eat together. Hiro, Megan, and Karmi were finally able to all shower together, as they weren’t willing to take that kind of chance back home, and greatly enjoyed the intimacy it provided. It was hard to resist doing more than just showering, but with the others waiting for them so they could all eat together, they had to hold themselves back from taking full advantage of their situation. For now, at least.
Dinner was buffet style, where many different kinds of food were available for the taking. When the three teens finally arrived, they found the others had already grabbed a table and Fred was already in the buffet line, filling his plate to ridiculous heights.
“Sorry about Fred,” Honey Lemon said when the others sat down. “We tried to make him wait until you got here, but it’s food, and it’s Fred.”
“It’s fine, we get it,” Hiro said, “but now that we’re here, is there anything we’re waiting for? I don’t know about you, but I’m starving.”
