Fan Fiction Sex Story: Chapter 16 - 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)

The three teens found Cass and Diego in the kitchen fixing breakfast. The adults were busy preparing quite the feast, with eggs, bacon, ham, toast, hashbrowns, waffles, several different kinds of fruit, and cereal put out if anyone wanted that. Both were casually dressed in bathrobes and looking very relaxed.

“Good morning, you three. Merry Christmas. Did you sleep well?” Cass said in greeting.

Hiro came over and gave his aunt a hug and a quick kiss on the cheek. From the brief feel from the hug, he wasn’t actually sure if she was wearing anything under her robe or not but it was best if he tried not to think about that possibility. “Merry Christmas, Aunt Cass. And yes, we did.”

“Since none of us got up early today, we figured we’d have breakfast first,” Diego told them. “You don’t mind waiting a bit longer before diving into presents, do you?”

“This all smells delicious,” Karmi said. “Is there anything we can do to help?”

“The food’s pretty much done, but you can help with setting the table,” Cass told her. “Do you remember where we keep the plates and cutlery?”

In practically no time at all, the table was set and everyone was enjoying the delicious meal. Megan did wince a couple of times when she twisted in a way that tweaked her sore muscles but thankfully neither adult seemed to notice. They all ate their fill, and the teens’ ravenous hunger was thankfully attributed to them simply being growing teens, and not because of the massive amount of calories they had burned the night before.

“We were beginning to wonder if you kids were going to make it down in time for breakfast,” Diego said when they were finishing up the meal. “You hadn’t come down by eight so I went up to check to see if you were awake yet.” That comment made the three teens freeze for a second but other than that they didn’t show any outward signs of fear. “Your room was empty, Megan, and I noticed something a little odd. You don’t normally make your bed before you shower, do you?”

“No, but I didn’t need to make my bed because I didn’t use it,” Megan answered, cool as a cucumber.

It took everything Hiro had to maintain a calm expression as Megan’s father gave him a not so subtle look. “Explain,” Diego said firmly.

Megan rolled her eyes. “Relax, Dad. Whatever it is you’re thinking is not what happened.”

“So you’re telling me you didn’t spend the night in a boy’s room?”

“No, I did,” Megan admitted. “Hiro, Karmi, and I had a slumber party in his room, that’s all.”

“With the door closed?”

“Yes, with the door closed,” Megan said, with just a little mockery in her tone. “That was your house rule, and this isn’t your house. Besides, the rule was to not to be alone with a boy. I wasn’t. Karmi was with us the whole time.”

Diego narrowed his eyes at his daughter, not liking her tone. “While you might be following the letter of the law, I feel you might be purposely ignoring the spirit of the law. And you know that doesn’t fly with me.”

“Oh really? And what is the spirit of the law, exactly?” Megan said, her own voice increasing in intensity to match her father. “Isn’t it so that I am never in a situation where a boy might try to hurt or take advantage of me?”

“Well, yes but-”

“But what, Dad?” Megan interrupted. “Karmi and Hiro are my friends, not to mention that they’re a couple. Do you really think Hiro would have done something to me with his girlfriend right there in the room with us? Or that they would do something with each other with me right there watching them?”

Diego blushed at the mere thought of something like that. “N-no, of course not!” he stammered.

“Then what?” Megan said harshly. “Please explain to us how I ignored the spirit of the law by spending the night with my two best friends?”

“I ... I...” Diego hesitated. He wanted to find some flaw in her logic, to find some reason to justify his feelings, but there was nothing. “I’m sorry,” he said, wilting in defeat. “I overreacted. You know I only want to keep you safe, right?”

Megan quickly came over and gave her father a big hug. “I know, Dad,” she said, her voice returning to its normal softness. “And I agree with you for the most part with the no closed doors rule, but don’t you think that rule is more for people who haven’t earned our trust?”

“You’re right, Sweetie,” Diego said, returning the hug. “And Hiro, I’m sorry for implying that I don’t trust you. I do. I know you’d never do anything to hurt my daughter.”

“Not in a million years,” Hiro agreed. “And with you and Aunt Cass being a thing, she’s essentially my step-sister. I have to look after my family, don’t I?”

Diego gave Hiro a smile and a nod. “Okay, I think I can exempt Hiro from the door rule, but that doesn’t address the fact that you did spend the entire night in a boy’s bed.”

“A bed that is so huge that all three of us could easily spread out so that we aren’t even close to touching,” Megan pointed out. “Plus I don’t think we ever had a rule about beds, just doors.”

“That’s because I never imagined a situation where such a rule would be necessary,” Diego replied.

“Then how about this? I will only ever spend the night in Hiro’s room if Karmi is there too.”

“Don’t you think that might be a little unfair to the two of them?” Cass asked, joining in on the conversation. “As you said, they’re a couple. If you’re with them they can’t exactly ... have a date night.” She had to alter what she was going to say because she was still too embarrassed to come right out and say they were having sex.

“It’s okay, Miss Cass,” Karmi said. “Last night was my idea. Megan wasn’t imposing on us at all. And I’m sure that in the future if Hiro and I ever wanted some privacy then she wouldn’t mind giving us some space.”

“Of course not,” Megan agreed. “I had a lot of fun last night and would have no problem doing it again but I would never stop you two from, you know, having some quality time together.”

“Alright, I think we can end this topic here,” Diego said. He was growing increasingly uncomfortable with their discussion as it veered away from the theoretical and into the practical regarding the teens’ sex lives, especially if Megan was a part of the conversation. “Why don’t we head to the main room and start opening some presents?”

“Since you two prepared everything, why don’t you go ahead and the three of us will tidy the table?” Hiro said to Cass and Diego. “We’ll have everything in the dishwasher in less than a minute.”

They all agreed and the teens started cleaning up the table but as soon as the adults were out of the room Hiro whispered harshly to Megan, “What the hell was that?”

“That was me saving your bacon,” she said smiling at him.

“By what, nearly exposing what we did?”

“I didn’t have much of a choice. Dad was already suspicious because of my room. You know from personal experience how stubborn he is when he wants to find out the truth of something. So I told him the truth.”

“Just enough of the truth to let him come to the wrong conclusion,” Karmi pointed out. “Have you ever considered becoming a lawyer instead of a journalist?” she joked.

Megan gave her a smile. “I’ve thought about it. But Dad did come to his own conclusion. Sure, it was the one I wanted him to have but now that he has an answer he has no reason to continue digging.”

Hiro gave a little sigh. “You’re seriously playing with fire here.”

“I suppose, but you can’t complain about the results. Nice touch with the whole ‘family’ thing, by the way. I was only hoping to maintain the status quo, but Dad actually gave some ground and the ‘no closed doors’ rule is essentially gone! I guess he can’t imagine a brother wanting to bed his own sister, even if they aren’t actually related. Just think about what we can get away with now!” Megan said with a twinkle in her eye.

Karmi smiled as well, thinking of the possibilities. “Yeah, I can’t believe he did that. But don’t go abusing that freedom too much,” she cautioned. “Not right away, at least.” She then turned her attention to Hiro. “That said, if you and Megan don’t have some one-on-one time before I get back from visiting my parents, there will be consequences.”

Hiro gave a little chuckle. “Please don’t take this the wrong way, but you have got to be the strangest girlfriend in the world. I mean, has there ever been a time where a girl threatened her boyfriend for NOT having sex with another girl?” He finished his words by giving her a quick kiss.

“I know, though I think I might have to share that title along with sharing you,” she teased, giving Megan a nod.

The three teens quickly cleaned up the rest of the dishes and joined the adults before they could start wondering what was taking so long. The gift opening took up a good chunk of the remainder of the morning with clothes, junk food, and games being the majority of the presents. Of note, Hiro did give Karmi some new earrings he made himself, using the plasma chamber at SFIT to create a pair of large artificial diamonds that he then cut using Wasabi’s laser cutting tech and set into some studs he personally machined. Naturally, she loved them and the resulting soul-searing kiss she gave him left even their audience feeling a little hot under the collar.

Sadly, Karmi had to be at the train station shortly after noon for the journey back home so she couldn’t stick around once the gift giving was over. Hiro accompanied her and they spent up until the very last second either kissing or holding hands, and no sooner had the train pulled away than Karmi was texting Hiro saying she missed him already. They continued texting as Hiro made his way back home, with Karmi once again reassuring Hiro that it was okay for him and Megan to do everything and anything they wanted to. He did make a detour to Headquarters to do something that needed to be done, but he tried to be as quick as possible so he could get back home without anyone wondering what was taking him so long.

Hiro was barely through the door when he was confronted by Megan. Standing in the hallway, she gave him a very seductive look that made him worried she might do something that would get them caught by the adults. “You gave Karmi quite the gift with those earrings,” she said as she strutted towards him. “Doesn’t your other girlfriend get a nice present too?”

Looking around to make sure they were indeed alone, Hiro reached into his pocket and pulled out a small box. “Actually, yes,” he said and held it out to her. “Though in my defence you weren’t my girlfriend as of twenty four hours ago, so this was kind of a rush job. I promise to give you something better as soon as possible.”

What Megan meant as a joke suddenly became very touching. She really hadn’t expected him to get anything for her and her expression quickly shifted from teasing to genuinely touched as she took hold of the box. Inside she found a hair clip, similar to those she always wore but the colour of this one was a dark shade of blue.

“I know it’s nothing special,” Hiro said as she took the hairpin out of the box and examined it more closely. “I had Basemax 3D print it while I was taking Karmi to the station. It’s supposed to compliment your eyes. I would have gone with a necklace or pendant or something if I had more time but figured something quick and simple was better than nothing at all.”

Megan answered by suddenly mashing her lips to his, kissing him with as much passion as Karmi had for her gift. Hair clip in hand, she wrapped her arms around him and hugged him tightly as she tried to show him how much his thoughtfulness meant to her. Caught off guard by the sudden intensity, it took Hiro a couple of seconds to respond and return the kiss, which they broke apart half a minute later. It didn’t last as long as either of them would have liked but both were painfully aware of where they were and of the strong likelihood that Cass or Diego could walk in on them at any second.

“Thank you,” Megan said. “I love it. You say it’s nothing special but it really is the thought that counts, as cliche as that might sound.” She took off the clip that she was currently wearing and replaced it with the new one. “How does it look?” she asked, brushing some stray hairs out of her face.

“Perfect,” Hiro replied, looking directly at Megan’s eyes and practically ignoring her hair.

She smiled then let out a sigh. “Now I kind of feel bad. I said the thing about a present as a joke but you went and already got one for me and I don’t have anything to give you in return.”

“That’s just not true,” Hiro said, shaking his head. “Last night you gave me your first time, and that is a gift way more special than anything you could have bought for me. I couldn’t give you my first because, well, Karmi, but I hope you don’t hold that against me.”

“Against you?” Megan grinned. “I know it would have been nice for us to be each other’s first but I can think of at least one thing that I’m very thankful for because I wasn’t your first.”

Hiro was confused by that. He was under the assumption that the ideal or at least most romantic way to have sex for the first time was to do it with your equally virginal first love. “Care to explain?”

“It’s simple. Since you already have a bunch of experience with Karmi, you knew exactly what to do to make my first time absolutely perfect. No awkward fumblings or not knowing what to do next.”

“Huh, I never really thought of it that way.”

“That said, I wouldn’t mind lowering the experience gap between us girls,” Megan said, briefly narrowing her eyes seductively and leaning in towards Hiro before backing away. “But not today. I’m still too sore.”

Hiro took a playful swipe at her behind as she skittered away. “Tease,” he complained.

“Not teasing. Promising. Tomorrow, or the day after at the latest, I’ll be ready for round two.”

“Round two of what, Sweetheart?” Diego said as he happened to be passing though the other end of the hall.

“Round two of a fighting game Hiro has,” Megan said without missing a beat. “He schooled me pretty thoroughly last time seeing as how I’d never played before, but next time I plan to come out on top.”

“Then you’d better watch out, Hiro. Megan can get pretty competitive when she wants to be,” Diego said.

“So I’ve noticed,” Hiro replied, trying his best not to blush from nearly being caught as well as Megan’s risky choice of words.

The remainder of Christmas day proceeded normally, complete with a nice big Christmas dinner. That evening Megan also got Hiro to teach her to play the game she had referenced. It wouldn’t do at all for her dad to someday challenge her to only find that she still had no idea how to play, plus it was a great excuse for her to be in Hiro’s room for hours on end.

Nearing bedtime Karmi sent a joint text to Megan and Hiro. “So did you two do it yet?” she asked, provoking a blush out of both of them.

Megan spared a grin at Hiro before responding. “Not yet. Too tender. Ask me again this time tomorrow.”

Hiro couldn’t help but smile and shake his head at how his two lovers seemed to already be fully comfortable with their linked sex lives.

“If you’re too sore for the full experience, have you thought about something less intense, like a 69?” Karmi prompted.

Megan’s eyes lit up at the idea. She looked over at Hiro with a huge smile, clearly letting him know what she thought of Karmi’s suggestion. There was also no chance of interruption as the adults had already gone to bed early because they had to be up and off to work at the crack of dawn the next day despite it being Boxing Day.

Hiro’s dick responded accordingly. “You are hands down the best girlfriend ever,” he typed as he watched Megan quickly pull off her shirt and unclasp her bra.

“Who? Me? Or Megan? 😉” Karmi teased.

It took Hiro a few seconds to respond as he was momentarily captivated by the sight of Megan bending over as she yanked down her pants and underwear in one go, leaving her fully nude. “Yes.”

“LOL”

“Got to go. Megan is already naked and trying to get my pants off. Talk later. Love you.”

“Love you too.”

Under normal circumstances, Hiro might have felt guilty for telling one girl he loved her while another girl was seconds away from sucking his cock, but considering that this was literally Karmi’s idea he could only feel happy beyond belief about his situation. He tossed his phone off to the side and helped Megan undress him in record speed. A few minutes later the two of them were doing just as Karmi had suggested, with Megan on top of Hiro, happily licking his dick while he ate her out from below, though was careful to be gentle when necessary so as to not cause Megan any discomfort due to her still quite tender labia.

Seeing as how this would be their only activity for tonight the two of them tried to make it last for as long as possible. For nearly half an hour they licked and teased each other, backing off when the other warned them, until they simply couldn’t hold back their orgasm any longer. With a moan, Hiro exploded into Megan’s mouth and less than a minute later Megan arched her back and climaxed all over Hiro’s face. They cuddled for a while, talking about this new aspect of their relationship, before Megan headed back to her room for the night. As much as they would have liked to spend the whole night together, without Karmi there as an excuse it was just too risky.

The next morning Hiro woke up and after a quick trip to the bathroom headed downstairs to see what his aunt was up to. Perhaps unsurprisingly, the cafe was full of clients having breakfast, despite it being the day after Christmas.

“I guess people were really eager to come back after our forced closure,” Cass said in explanation. “It looks like we might have even more customers than before.”

“Do you need an extra hand?” Hiro asked.

“That’s for asking, but Noodle Burger Boy and the other robots are more than enough help. You just relax and enjoy your time off, okay? Considering all the work you put into rebuilding this place I think you’ve more than earned it.”

“Okay,” Hiro replied, then a thought came to him. “Um, how long will the cafe be open today? Regular hours?”

“That’s the plan, unless things suddenly die off in the afternoon. You and Megan will have to look after lunch for yourselves unless you want to come down to eat here.”

“We might just do that. Love you, Aunt Cass,” Hiro said, before giving her a hug then headed back upstairs, his excitement growing with each step.

With only a little hesitation, Hiro knocked on Megan’s still closed door. Getting no response, he quietly opened it and entered her room, shutting the door behind him. He found Megan still asleep in her bed, her bedsheets tossed aside as she moved about in her sleep. Hoping he wasn’t overstepping, Hiro stripped down to his underwear and crawled into bed next to his new girlfriend before gently stroking her face to coax her out of dreamland.

Megan sighed at the gentle touch, then her eyes slowly opened as sleep left her. For a second she tensed up as she realised someone was in bed with her, but relaxed and smiled once she noticed who it was. “A bit risky, crawling into bed with me like this, don’t you think?” she said.

Hiro returned the smile. “Not really. Your dad’s already left for work and Aunt Cass is busy serving customers so she won’t be coming upstairs any time soon.”

“So what you’re saying is there’s no chance of being interrupted?” she asked, noticing that he had no shirt on.

“How are you feeling today? Still sore?” They both knew Hiro was asking for more than just a concern for her well-being and comfort.

Megan sat up and stretched. “Not sure. I’m still just waking up. Bathroom and breakfast first, then we’ll see.”

As nice as it would have been to have a big hot breakfast down in the cafe, Megan didn’t want to make a public appearance in just her pajamas and with her hair still a mess. Instead the two teens made eggs and toast for themselves in the apartment kitchen before heading back upstairs to ‘their’ floor.

“So what did you feel like doing today?” Hiro asked as they reached the fourth floor. It was clear what kind of answer he was looking for but he wasn’t quite bold enough to come right out and ask.

Since Hiro was being a little coy, Megan decided she could do the same. Heading towards the bathroom she said. “I’m not sure, but before I do anything else I want to have a shower.”

“Speaking of showers, I haven’t had one yet either,” Hiro said. “Maybe we could share? The shower’s definitely big enough, and I seem to remember you once said something about saving water.”

Megan turned and grinned at him. “Nice try,” she said, then stepped into the bathroom and closed the door in Hiro’s face. His disappointment was short lived, though, as a few seconds later Megan opened the door and yanked him inside.

They did shower together, but there was no saved water. In fact, they probably wasted three times as much water as was normal had they showered separately, due to the fact that they spent nearly an hour kissing, touching, and having sex while the water continued to run.

After each of them had come at least once they decided that they were in the shower long enough, though they still took the opportunity to grope each other under the excuse of using towels to dry each other. Once dry, or at least dry enough, with a mischievous grin and a cautious peek out into the hallway, the still quite naked Megan grabbed the equally naked Hiro by the hand and dragged him out of the bathroom and into her bedroom. The short trip from room to room did nothing to cool her off and as soon as her door was closed she was stroking Hiro’s dick and kissing his neck.

“Again?” Hiro asked, both surprised and thrilled at Megan’s eagerness.
