Back at the Cruz’s, Cass had some rather disappointing news regarding the reconstruction of the Lucky Cat. While the demolition of the old building was already complete, there was so much red tape and restrictions on the rebuilding phase that it would take months, if not years before they would be able to reopen again.
“This is utterly ridiculous!” Cass complained. “Do they have no idea how important it is for a service business to remain open? If I can’t open up for a whole year I might not have any customers left by the time I do! They’ll all have found another cafe to go to by then!”
The thought of his aunt losing her business was not something Hiro liked, nor was having to deal with Megan’s teasing for that long a time. Not that he didn’t like her company, but he already missed his old room and couldn’t really customize this one the way he’d like. Not to mention he didn’t feel comfortable with inviting Karmi to stay the night in a room that wasn’t really his. Another thought occurred to Hiro, one that could help him in more ways than one. “Why not skip the insurance?” he said. “Or at least skip having them in charge of rebuilding things. Take the money, buy the materials, and I’ll rebuild it for you.”
Cass raised a skeptical eyebrow. “Um, you? I don’t mean to sound rude, Sweetie, but how in the world do you think you could pull that off?”
“My microbots,” Hiro said. “Their original purpose was to help speed up construction, after all, but because of what happened with Tadashi and Callahan I mostly shelved the project. However, I think it might be time to give it another go. The upcoming term at school I have an independent research project but I haven’t decided on a topic yet, so if I can make that project testing the feasibility of my microbots in a real-world scenario I can kill two birds with one stone. I’ll have my research project and we’ll get our home back in a month, month and a half, tops.”
“Are you sure you can handle that much work? School, hero work, and now rebuilding our home?” Cass asked, hopeful but not wanting to overburden her already busy nephew.
“Of course! Like I said, this would be a school project so I wouldn’t actually be taking any extra time to do it.”
Cass thought about it for a bit, weighing out the pros and cons and thinking through possible pitfalls. Eventually she gave a nod. “Well, okay then. Let’s give it a try at least. I’ll still need someone with expertise to double check everything you do, of course, but when do you think you can get started?”
“I’ll have to manufacture enough microbots first but that’s a fully automated process once I get started. And I’ll need Professor Granville’s approval. So, maybe a week? Less if I could simply have the microbots that Callahan built,” he added and looked questioningly over at Diego.
“I’m afraid those bots are all considered evidence,” Diego said. “So, no, I can’t give them to you.”
“That’s alright,” Hiro said, shrugging his shoulders. “Like I said, making the microbots is fully automated so all I really have to do is make sure I have enough raw materials for them, that’s all.”
“Then I’ll get in touch with my foreman and make sure you’ll have everything you need by the end of the week,” Cass said. “But before that, why don’t you invite your girlfriend over for supper sometime soon? I still haven’t had the chance to properly meet her.”
A quick phone call to Karmi after their meal was over had her happily agreeing to come for supper the day after next.
When Hiro had finished getting ready for bed his room was invaded by Megan, who was also dressed for bed in her distractingly loose oversized t-shirt. “So, Karmi tells me you’re quite the ‘cunning linguist’ when the two of you are alone,” she said as she hopped onto his bed.
Sitting at his desk, Hiro understood her meaning and his ears immediately turned red. Evidently the two girls had been going into an embarrassing amount of detail as to what he and Karmi got up to in private. “I am not going to give you a blow by blow description about what Karmi and I do on our dates,” he protested.
Megan arched an eyebrow at his choice of words.
It took a second but then Hiro realised what he had said. “You know what I mean!”
Megan grinned back at him. “Oh, I definitely know what you mean.”
Hiro let out a tired sigh. “Did you come here just to torment me or was there something important you wanted to say?”
“Mostly the former, actually,” Megan teased. “But I did want to let you know that I have several school projects coming due this week so I probably can’t hang out like I did today.”
“That’s good to know. As much as I appreciate your company, I don’t want you sacrificing your grades for no good reason.”
“He has a point,” Diego suddenly added from the doorway. “I know you told me before that you weren’t behind with any of your schoolwork but I don’t want you wasting the entire weekend. Tomorrow you’re hitting the books, young lady.”
“Yes Dad,” Karmi replied, and Diego headed off to his own bedroom. “Well, I should head to bed too. While I didn’t have nearly as exciting a day as you did, it still was a long one.”
Hiro agreed but when Megan moved to hop off the bed, she accidentally knocked one of the pillows down. “Whoops, sorry ‘bout that,” she said and grabbed the pillow off the floor.
Hiro took in a sudden breath as he looked over at what Megan was doing. With her bending down to pick up the pillow, her dangerously loose shirt revealed exactly why it was so dangerous. He now had the perfect view down the neck of Megan’s shirt, where one fully uncovered breast was on full display and the other was nearly as visible.
Megan heard the gasp and glanced up at him “What wrong?”
Hiro gulped, trying hard to not let his eyes drift to where they’ shouldn’t go. “Have ... have you ever considered wearing something else to bed?” His eyes flashed towards his open door, slightly relieved that if Diego were to return, he wouldn’t be able to tell that Hiro had an unobstructed view of his daughter’s breasts.
“Why would I want to do that? These are my comfiest pajamas,” Megan said. She shifted slightly, causing her breasts to jiggle, and Hiro’s eyes automatically darted down to them for a moment before he brought them back up. She noticed his glance and looked down at herself, finally noticing how much she was showing off.
“Maybe so, but they, um, they don’t exactly hide much,” Hiro said, managing to keep his voice relatively steady. He kept his eyes from staring directly at Megan’s exposed nipple but pretty much everything was still quite noticeable in his periphery.
“So I see,” Megan replied coolly. Rather than sit up or cover herself like Hiro expected she actually bent lower, giving Hiro an even better look, and gave him a smile. “Enjoying the view, are you?”
Hiro blushed. “Shouldn’t you maybe cover up?” he asked, avoiding the question. He was of two minds about this, as he really was enjoying the view but just as much he wanted to respect both his girlfriend and his friend by not ogling the wrong girl. Given that he was in a relationship, he probably should have turned away but with Megan blatantly allowing him to look, he lacked the willpower to do so.
“It’s nothing you haven’t seen before. You even have a picture of the twins, with Karmi’s permission, no less,” Megan reminded him. “In fact, you could probably take another picture right now to add to your collection.”
“I, uh, I don’t think Karmi would appreciate that.”
“Why not?”
“That image from earlier was a slip. An accident. Considering that we’re both fully aware of this one and you still haven’t covered up means it’s no longer an accident.”
“An accident? I didn’t think you were that naive. Do you really think I couldn’t tell how low my towel was? Besides, you still haven’t looked away,” Megan said, giving him a knowing smile.
Being called out so directly finally gave Hiro the resolve to finally do just that. He spun in his chair so that his back was towards Megan, both relieved and disappointed that he could no longer see her bare chest.
“Why don’t you ask her?” Megan then said.
“What?” Hiro replied, keeping his back to her.
“Why don’t you ask Karmi if she would be okay with you taking a picture of me?”
Deciding that bringing Karmi into this situation to act as his backup would be a good idea, Hiro grabbed his phone and sent her a video call. “Just so you know, I’m not calling her to ask permission, I’m calling her to tell her what you’re doing.”
“Same difference,” Megan replied, the smile evident in her voice.
Karmi’s face appeared after a couple of rings. “Hi, Hiro. What’s up?” she asked cheerfully.
“Hey Karmi. I need your help. Megan’s sexually harassing me again.”
“What? I am not!” Megan said, feigning indignation.
“What did she do this time?” Karmi asked, a slight grin appearing on her face as she played along.
“I don’t know if you’ve seen what she sleeps in but she’s wearing a very wide-necked t-shirt for her pajamas, and she bent over so that I could see literally everything.”
“Did she know?”
“Maybe not at first, but when I told her she just kept doing it.”
“And is she still putting on a show?”
“I don’t know. I turned my back to her but I’m assuming she still is.”
“I am,” Megan helpfully chimed in, loud enough for Karmi to hear, but hopefully not so loud that her dad would overhear. “And you only turned your back after nearly a minute of looking,”
“She also told me to take a picture,” Hiro added. “And to call you to ask permission.”
“So you’re actually asking me for permission to take pictures of another girl’s boobs?”
Hiro really wished Karmi’s face was a little more emotive right now because it gave no hint of if she was angry or amused at his situation. “No! I’m just telling you what she’s doing, that’s all!”
“Let me see.”
“What?”
“I want to know if it’s really that big of a deal or not. If you don’t want to turn around you don’t have to, just angle the phone over your shoulder so that I can see.”
Realising he wasn’t going to get the help he was hoping for, Hiro did as requested and raised the phone so that Karmi and Megan could see each other.
“Hey Karmi,” Megan said cheerfully.
“Hey Megan,” Karmi replied, just as friendly. “What are you doing now, besides trying to seduce my boyfriend?”
“Looking under the bed to see if Hiro has any naughty magazines hidden there.”
“What?!” Hiro couldn’t help but blush at the accusation but resisted the temptation to turn around and face her directly. “I don’t have anything like that! And even if I did, I wouldn’t hide it in such an obvious spot. You’re just making up excuses to stay bent over, aren’t you?” he accused.
“Maybe,” she answered.
“Well, you were right about one thing,” Karmi said. “You can totally see everything. Megan might as well be completely topless for all that is being covered.”
“Hey, that’s not a bad idea,” Megan teased. “Maybe we could try that at some point. Have me stand behind Hiro with next to nothing on and see if he has the willpower to not turn around. It’s too risky to do that here though, with my dad’s policy of no closed doors.”
Hiro sighed a breath of relief, but almost as if some unseen force was working against him, he and Megan heard the uncomfortably familiar sounds of sex coming from down the hall, clearly indicating the two adults were quite thoroughly occupied. “Ah shit,” he swore.
“What? What’s wrong?” Karmi asked. Clearly she couldn’t hear the soft moaning through the phone.
“Nothing’s wrong,” Megan said, a wicked grin spreading across her face. “It’s just that we can hear my dad and his aunt going at it, which means the chances of him checking in on us just went from ninety percent down to zero!”
Suddenly Hiro could hear the sudden rustling of clothing.
“Oh my god! Megan!” laughed Karmi. “You’re so bad!”
“Please tell me she’s not...” Hiro began, glancing away from his phone so that he could not see what his camera was recording. Something flew by his head and landed on his desk. It was Megan’s shirt.
“You’re lucky I trust you, Megan, and that I trust Hiro,” Karmi said, not knowing whether to feel scandalized at what Megan was doing or to burst out laughing at Hiro’s predicament. “Otherwise I’d be digging a couple of shallow graves by this time tomorrow.”
“Trust, huh? How much do you trust us?” Megan said, the teasing heavy in her voice. “Just tell me to stop and I will.”
Karmi thought for a second, then looked at her boyfriend with a mischievous smile. “ ... Hiro?” she said.
Hiro gulped. “Yes?” he said, sparing a brief glance at his phone so he could see Karmi while trying to ignore the bare chested Megan that appeared in the corner of his screen. Both girls seemed to have forgotten that with video calls, the sender had a small window in the corner showing everything their own camera captured, though he wasn’t about to remind the girls of that right now.
“Don’t turn around. If you can do that, I promise to make it up to you tomorrow.”
Then came the sound of more rustling clothes behind him. Hiro’s heart hammered in his chest as he couldn’t help but imagine what was taking place directly behind him. The rustling stopped and the room became eerily silent save for the muffled sounds coming from the master bedroom. Several seconds passed before he spoke. “Is she...?” he began, but dared not finish the question.
Karmi nodded. “Naked as the day she was born,” she said, grinning at him. “And striking a pose.”
“So Hiro, wanna turn around and have a look?” Megan said, her voice suddenly and unexpectedly right next to his ear.
Goosebumps sprang up everywhere on Hiro’s skin and he could tell that his entire face was as red as a tomato. Megan was so close he could actually feel her body heat on the back of his neck. He had to close his eyes for a moment and take a deep breath to try and calm himself. “I’m not going to lie. I’m tempted. Very tempted,” he said, the tremor in his voice making his inner struggle rather obvious. “But ‘want to’ and ‘going to’ are two very different things,” he added, admitting to both girls what he was feeling. Megan might be a tease but she was unquestionably hot, and with her being completely naked mere inches away from him it would be an obvious lie to say he didn’t want to look. “However, Karmi has made me an offer I’d be an idiot to refuse. I’ve seen the marshmallow test and I’m not going to fail just because the, um, treat is much better than marshmallows.”
“Though in our case, it’s not a matter of eating one marshmallow now or two later, but looking at one marshmallow now and eating a different one later,” Karmi pointed out.
Megan giggled and said, “Oh, I don’t know. If I’m to be compared to a marshmallow, I don’t think I’d be too opposed to it if Hiro were the one doing the eating.”
A vision of Hiro eating out Megan popped into his mind. It was a very dangerous thought and he knew that he had to do something before he completely lost control. “Enough!” he said loudly and he stood up from his chair so fast that it nearly fell over. With that outburst, the sexual tension that had been rapidly building burst like a balloon. He grabbed Megan’s shirt and held it behind him while he squeezed his eyes shut. “Please!” he said, much more gently. “I don’t know how much more of this I can take, and I really don’t want to do something I know we’ll all regret.”
Megan took her shirt and moved several steps away from Hiro. “Sorry,” she said as she slipped her shirt back on. “I guess things did get a little out of hand. I didn’t mean to upset you. You, um, can open your eyes now.”
Hiro did so and tentatively turned around so he could look at Megan while he talked to her. He gave out a relieved breath when he saw she was indeed covered up once more. “I know, and I’m not upset. But we were dangerously close to a line that cannot be uncrossed, and all that teasing still has me so turned on I can barely even think straight.”
“Yeah, I know what you mean. In the heat of the moment all I could think about was what could I get away with next. I was like a dog chasing a car and I had no idea what to do if I actually managed to catch it. So, thank you, for, you know, not turning around. And Karmi? I’m sorry if I overstepped. Please know that I never would have gone that far if you weren’t, um, present.”
“No, you’re okay,” Karmi replied. “I gave you the go-ahead so I’d be a pretty lousy friend if I were to be angry with you now. But be honest with us, how far would you have taken this if I wasn’t here?”
“Honestly? I probably would have still taken off the shirt. But the rest? No, I don’t think so. I do trust you, Hiro, but you’re still a guy.”
“Thanks,” Hiro replied dryly.
Megan gave him a wink then brought her focus back to Karmi. “Still, I’d like to make it up to you somehow, so just tell me what to do and I’ll do it.”
“Well then, would you mind giving Hiro and I some privacy? We do have things to discuss and it would probably be best if we were alone.”
“Of course! I’ll just head off to my room for the night, then. We’ll talk later.”
“Yeah, see you.”
Megan hurried out of Hiro’s room, closing the door behind her. However, a few seconds later there was a knock and Megan poked her head back in again. “Sorry, I accidentally left something behind,” she said.
“What is it?” Hiro asked.
“That.” Megan answered and pointed to a little pile of something in the middle of the floor.
It took Hiro a second to realise that what he was looking at was Megan’s shorts. And her underwear. Reflexively he looked back at her, his eyes darting straight to her waistline. Now that he looked closely, he could easily tell she wasn’t wearing anything down below. Her t-shirt was long enough to cover her crotch, but not by much. He closed his eyes and rubbed them in exasperation. “Are you sure it was an accident?” he asked.
“Yes! I’m really sorry.”
“Well, come get them, then,” he said. He had momentarily thought about giving them back himself but touching her freshly worn underwear for any reason felt like he would be going too far.
Megan darted back into the room and picked up her discarded clothes. Hiro noted that she bent at the knees, not the waist, and that she used one hand to hold her shirt to her chest so there wouldn’t be any other exposures, accidental or otherwise, for which he was very grateful. When she stood back up and looked at him, he could tell she was debating with herself if she should get one last little tease in or not, but then she simply said goodnight and left the room. Hiro let out a sigh of relief.
“Sorry about all that,” Karmi said. “Are you okay?”
“I should be the one asking you that,” Hiro said, taking another deep breath to help calm himself. “Regardless of the circumstances, I just had a naked girl in my room. Are you really going to tell me you’re okay with that?”
“Megan was naked, true, but you didn’t do anything to each other and you never saw anything other than that initial down-blouse. Am I okay with that? In a sense, yes. Remember that I’m a bio-chem expert. I probably know male biology better than you do. I know, academically at least, how powerful the instinct is for a guy to, um, spread his seed. Yet in spite of that you did more than just not look, you actively put a stop to it in order to stay loyal to me. That earned you a lot of points.”
“A lot of points, huh? So is there some sort of prize I get once I earn enough?” Hiro grinned.
