“So, Spring Break is coming up,” Hiro told the other members of the team as they all sat around their conference table. “I know Wasabi, Honey Lemon, and GoGo all have jobs, but I was wondering if you’d be interested in doing something together, maybe go somewhere or something.”
“Like go on vacation together? I think that’s a wonderful idea!” Honey Lemon said.
“I like it,” Wasabi agreed. “We never seem to do anything as a group anymore unless it’s Big Hero 6 related. It’d be really nice to get out of the city and just relax and have fun together.”
“Spending quality time together with friends helps with many areas of mental health, such as anxiety, stress, and self-esteem,” Baymax added.
“What about hero work?” Fred asked. “Just because we go on vacation, doesn’t mean supervillains will take a break too.”
“We have Base-max to monitor things, and we can leave Mini-max to deal with any smaller stuff that pops up,” Hiro said. “Plus we can use the Sky-max armour delivery system to fly us back quickly if something more serious does pop up.”
“Okay, but since you were the one to bring it up, did you have something specific in mind?” GoGo asked Hiro.
Hiro nodded. “Maybe. Fred mentioned a while back that his family owned their own private island. While I was researching things, I found out that they actually have a resort there that’s open to the public.”
Everyone turned to look at Fred, who shrugged. “Yeah, there is. It’s great and all but they’ve got this one really dumb rule so I’m not the biggest fan,” he said.
“Care to explain?” GoGo asked.
“You see, the resort is divided in two,” Fred said, using his hands to demonstrate. “One half requires you to wear clothes, the other half doesn’t.”
“What!? You actually own a nude resort!?” Honey Lemon asked, clearly quite shocked.
“No, weren’t you listening? The resort is clothing optional, not nude. And that’s only for half of the island. Stupid, right?”
“Hold on,” Wasabi cut in. “Are you saying the clothing optional part is stupid, or that it’s for only half of the island?”
“The ‘only half’ part, obviously,” Fred answered, rolling his eyes as if to say that was a dumb question. “Almost all of the guests come so they can get naked at the beach but the other side has the best ones. It sucks that you can’t work on your tan or go skinny dipping while at the nicest beaches. It’s dumb.”
“Hiro, you said you did some research on this,” GoGo pointed out. “Did you know about the whole clothing optional thing?”
Hiro’s blushing face was confirmation that yes, he did know. “I might have read something along those lines,” he said, trying to brush it off. “But the pictures they showed of the place were absolutely beautiful. And there’s no rule that says we’d have to go to that side. Like Fred said, the best beaches are the ones that require you to stay dressed.”
“Uh huh. I’m sure that’s all you had in mind,” GoGo said, giving him a knowing grin. Hiro’s blush deepened as he remembered when he accidentally saw GoGo naked back at her apartment. “Well I’m fine with it, so long as Fred can pull some strings.” she added with a shrug. “I haven’t saved up nearly enough to have a week-long vacation at a luxury tropical resort. And like Hiro said, it’s not like we’d HAVE to get naked even if we went to the clothing optional side, right?” The way she said that made Hiro believe she had no intention of doing things that way.
“Yeah, but you’d stand out like a sore thumb if you did,” Fred pointed out. “And I’ve totally got you guys covered, not just because my folks own the place, but because we’re Big Hiro 6, and we totally have earned some vacation time.”
“So, all in favour?” GoGo asked.
“One question,” Wasabi said. “This place is outside of any country’s jurisdiction, right? Are they still OSH and FDA compliant?”
“Huh?” Fred asked, not recognizing those acronyms.
“He’s asking if everything is safe and clean,” Honey Lemon clarified. “Germ free and stuff like that.”
“Oh, yeah, totally. You can’t be clothing optional and not have a heavy emphasis on sanitation. You even have to have a health check before you go to make sure you don’t have something that could make any of the other guests sick. That place is about as germ free as you can get outside of a sealed lab.”
“That is a very good policy,” Baymax said. “Without clothing to act as a barrier, things like urine or fecal matter could be deposited on cushions or chairs. STIs and other infections can easily spread in such an environment if surfaces are not cleaned regularly.”
“Ew, gross. Too much information, Baymax,” GoGo said. “We know about that stuff so you don’t need to explain it to us.”
“My apologies, GoGo. I just wished to ensure that everyone is aware of any potential health concerns.”
“What about inviting some other people?” Hiro asked, steering the conversation away from the messier side of being naked around others. “Megan’s practically an honorary member of the team, and I’d really like to bring Karmi along if I could.”
“I’m sure you would,” GoGo teased. “Though if we did that I suppose we should invite Olivia to come along too, right Fred?”
“Could we? That’d be great!” Fred said enthusiastically. “We’ve kind of been to a nude beach, but not really because we used the simulator. Olivia’s never actually gone to a real one before and would really like to experience the genuine article.”
“Why am I not surprised?” Wasabi said.
“I guess that answers the question of what side you’ll be spending your time on,” GoGo teased.
“I suppose one of the benefits of having a clothing optional side is that you don’t have to bring as many extra outfits,” Honey Lemon pointed out. “Though maybe some extra sunscreen would be warranted. I certainly don’t want my girls getting sunburned. That would not feel nice at all.”
“Oh? Are you thinking about going over to that side?” Fred asked, genuinely curious. “It’d be great if Olivia and I could hang out with you guys there.”
Hiro knew Fred didn’t mean it that way, but he couldn’t help but blush at the association that now came with the words ‘hang out’. For a moment he imagined everyone from Big Hero 6 naked and in bed together while Honey Lemon, GoGo, and Olivia were all having sex with Wasabi, Fred and himself. He had thought that having two girlfriends, and the increase in the amount of sex he was having, would dampen his sex drive but instead he was thinking about sex so often that he was even thinking perverse things about his friends.
“I’ll admit I’m a little curious,” Honey Lemon said, blushing. “I had no issues with the communal showers at SFIT, though that was a women’s only space so I’m not sure how comfortable I’d be with being naked around a bunch of strange men.”
“But you’d be comfortable around a bunch of friends?” GoGo teased.
Honey Lemon looked at Hiro and gave a small smile. “Probably. I’ve never gone skinny dipping before but it’s something I think I’d like to try at least once. And while I burn easily, I do like the idea of having no tan lines.”
“So is that a yes to us going?” Hiro asked, trying not to show how excited he was at the possibility of seeing Honey Lemon or GoGo without any clothes. “We’ve talked about some pros and cons but nobody’s said no yet.”
“I think it’s a yes for us around this table at least,” GoGo said, to which the others all nodded. “But we do have some other things to consider. We’ll need to ask Karmi, Megan, and Olivia, of course, and your aunt, Hiro, and Megan’s dad. You are still minors after all.”
“I also have a question,” Baymax said. Rather curious as to what the robot might have to ask about, the others told him to ask. “Would my outer shell be considered clothing? If so, would I be expected to remove it when at the beach? And if not, would that mean I am naked right now?”
“I suppose if we had to make a comparison then your shell would be the equivalent of a human’s skin, so technically you are naked,” Hiro said. “But considering that you are a robot and don’t have any, um, private parts, there’s no point in you wearing clothes, either. Plus if you were to take your shell off at the beach your joints would get gummed up with sand, which is definitely something we want to avoid.”
“Understood,” the robot replied.
Back home, the word ‘resort’ was barely out of Hiro’s mouth when Karmi and Megan enthusiastically agreed. Not wanting to scare them into changing their minds, he hesitated for a second before going into details about the dress code, or lack thereof. At first the girls were indeed concerned with the idea of being nude out in the open but as they thought about it they decided that it could be a very fun experience. And since being naked was optional, they did not change their minds about going.
“So Hiro, were you hoping that you would get the two of us to strip down while we were there?” Megan teased once they were firmly decided about going.
“The thought had crossed my mind,” he replied, giving her a grin.
“I’m sure it did,” Karmi said, grinning along with the other two. “Though if we did, that would mean other people would see us naked. Are you okay with that?”
“I am if you are,” he said. Other people seeing his girlfriends in all their glory wasn’t something he was particularly thrilled about but the prospect of them being naked all day long more than made up for that. Plus seeing was a far cry from touching.
“And I hope you weren’t expecting us to do it alone, were you?” Megan asked. “If you want us to go full nudist then I hope you were planning to, as well.”
“Of course,” he answered as calmly as he could. That idea was equal parts exciting and scary, but Hiro was sure the resulting reward would be more than worth any sort of embarrassment.
“And you’re not bothered with the prospect of seeing your other friends naked or them seeing you?” Karmi asked.
“Well ... it wouldn’t be the first time, actually. For some of us at least,” Hiro said, somewhat reluctantly, which caused both girls to give him a look of curiosity. He then went on to explain his encounter with Honey Lemon and GoGo where he had seen the latter fully exposed, and of the video Fred shared with the group showing him and Olivia having sex. The girls were understandably concerned at first but then curiosity and mirth gained prominence.
“So do we need to be concerned about Honey Lemon or GoGo trying to seduce you while we’re on vacation?” Karmi asked, only somewhat jokingly.
“No, I’m sure they wouldn’t do anything like that,” Hiro said.
“How sure are you?” Megan asked. “It sounds like they are pretty open to sharing a guy, right? You specifically. And you’re already being shared, so...”
“But as far as they know I’m still monogamous,” Hiro pointed out.
“For how much longer?” Karmi asked. “I can’t see us going on this trip and them not figuring it out at some point. And when they do, would they want to be included?”
“Even if they did, I’ve already got my hands full with the two of you. Literally,” Hiro said, wrapping his arms around their waists. “I have no desire to increase my number of girlfriends.”
“If you’re going to lie, at least make it believable,” Megan teased, twirling a finger around on his chest. “No desire? Come on, we all know how hot those two are. Even though you already have us, you’d have to be dead or gay not to want to sleep with one of them, let alone both of them.”
“And you’re definitely not either of those things,” Karmi added, running her hand playfully over Hiro’s crotch and his rapidly growing hard-on.
“Be that as it may,” Hiro said, trying to control himself and not just toss the both of them onto his bed and have his way with them. “I still wouldn’t do anything with them.” He paused for a moment, then added, “Without your permission.”
That got a laugh out of both girls before they pulled him towards the bed themselves.
The next step, and this would be pretty tricky, was to convince the adults to actually let them all go, but Megan stepped up and took that task on herself. Somehow, with a bit of research and some carefully selected images and pages from the resort’s website, the following day she made a very convincing presentation to Cass and Diego, making the case for why her dad should allow her to go with Hiro and his friends. She also pointed out how it wouldn’t cost them anything as Fred was financing the whole thing. Not once did the fact that the resort was clothing optional ever come up and the adults never even thought to ask that kind of question.
Diego was still naturally hesitant to let his daughter go on such a trip. The two of them had never been apart for that long or for that great a distance. He actually offered to come along and act as a chaperone but Megan shot that idea down pretty quickly, insisting that it wouldn’t be necessary as almost everyone going was an adult, plus with her and Hiro gone Diego and Cass would have the entire apartment to themselves for the whole week.
“Come on, Diego,” Cass said, giving his hand a comforting squeeze. “Let the kids go have a little adventure. You know they’re more than capable of looking after themselves and each other.”
Diego let out a sigh of resignation which made Megan immediately cheer for joy, but he held up a hand to settle her down. “I have a few conditions,” he told her firmly. “First, you make sure you stay on top of your schoolwork. If any of your teachers give you something to do over the break then it will get done, either before you go or while you’re there. Secondly, you call every day. Not text. Call. Just to check in with me. If I don’t answer, leaving a message is fine. Thirdly, no alcohol. I know a resort wouldn’t knowingly serve someone who’s underage, but I also know how such rules can be bypassed so I’m telling you now, don’t even try. And lastly, don’t ever go anywhere alone. Always have someone you know and trust with you. If you can promise me that, I’ll let you go.”
Megan jumped up and gave him the biggest hug she could. “Thank you, thank you, thank you! I promise, Dad,” she said, with full sincerity.
“And you,” Cass said, directing all her attention at Hiro. “I know you’re the same age but if Megan is going with you then her safety is your responsibility, understand?”
“No problem, Aunt Cass. I’ll have both eyes on her as often as possible. And if I can’t, I’ll make sure Karmi or someone else can.” Of course he hoped that she would be completely naked for a good portion of that time, but his aunt didn’t have to know that.
As the date of their departure drew closer everyone could feel the excitement building, even those who were going to stay behind. Megan even asked her teachers for any work early so that she could do it all before she left. There was also a shopping trip by all the ladies to buy new bathing suits, although they joked that it might end up being a waste of time and money. The adults in the group were pleasantly surprised at how the youngest members eagerly joined in on the banter. The group also sorted out the sleeping arrangements. Fred and Olivia would be sharing a room and bed, obviously, and it made sense for Honey Lemon and GoGo to share since they were already roommates. Karmi and Megan were more than happy to share a room and so were Hiro and Wasabi with the caveat that they had separate beds, though secretly Hiro wondered how many nights he’d be spending in that room, if any. Baymax’s charging station would also be located in Hiro’s room, but that could easily be rearranged if necessary.
The day before their flight, Karmi and Megan were packing the last of their things together at Hiro’s house when Hiro got an unexpected text from Honey Lemon. “Hi Hiro,” it read, “Are you all packed? Ready to go?”
“I am,” he replied, having put the last things in his own suitcase about ten minutes ago. “You?”
“Yes. Well, almost. I wanted to try on my new bathing suit one more time before packing it up. Now that I’m wearing it I wouldn’t mind a guy’s opinion. Mind giving me some feedback? I’m worried it might be a bit too skimpy.”
Hiro felt himself instantly heat up at the thought of a beautiful woman like Honey Lemon modelling some barely-there bikini but he also had to chuckle considering that even the skimpiest bathing suit would still cover more than nothing at all if she did decide to go the clothing optional route. As much as he wanted to see her nearly naked he didn’t think it was appropriate, not without Karmi’s permission at least. ‘Good thing she’s right here,’ he thought and gave her a nudge before showing her his phone.
“Too skimpy?” Karmi said, reading the message. “Did she forget where we’re going?” she asked sarcastically.
Curious, Megan came over and read the message as well. “Nah, she just wants to show off,” she concluded. “Should we let her? Us girls saw it at the store so I can say it is pretty hot.”
“Sure. I don’t mind,” Karmi said.
“You two are the best,” Hiro said, giving each girl a quick kiss, then texted a reply to Honey Lemon. “Sure, but just so you know, Karmi and Megan are here with me. Anything I see, they’ll see.”
“That’s no problem,” Honey Lemon answered. “Hey, if we make a little text group then we could all compare outfits!”
“I’d say okay but we’re already packed,” Karmi pointed out.
“That’s no problem. We already have pictures of what we’re going to wear. We can just share those,” Megan said.
“We do?” Karmi asked, not quite sure of what pictures Meagan was referring to.
“Yeah.” Megan then leaned over and whispered into the other girl’s ear, too quietly for Hiro to overhear.
“Oh, those pictures!” Karmi said, blushing slightly. “Are you sure?” she asked Megan, who nodded.
With the girls now on board Hiro invited them into the text conversation and after some quick hellos between them and Honey Lemon, the older woman sent them a selfie of her in her new bathing suit. She was wearing a strapless pale green bikini with a frilly skirt as part of the bottoms. The amount of skin on display left little to the imagination, but with her hair done up in a bun and her face looking slightly antsy she was in a word, adorable.
“So what do you all think?” she asked.
“Very nice,” Karmi replied.
“Very sexy!” Megan sent.
“What they said,” is how Hiro answered.
“So you don’t think it’s too revealing?”
“Considering where we’re going, I’d say it’s not revealing enough!” Megan teasingly wrote.
“If you think that then you should totally get a look at GoGo’s outfit! Give me a minute to see if I can convince her to show it to you.”
