Karmi walked quickly down the hall to try and catch up to Megan. “Megan, wait up!” she called. The other girl did slow but not by much, and it took Karmi another few seconds of nearly running to reach her side. “What happened?” she asked, genuinely concerned.
“Nothing,” Megan said, though her tone of voice made it obvious something had. “It’s not a big deal, really,” she added with a sniffle. The fact that she had to wipe away a few tears stole away any truth in those words.
Karmi had very little experience dealing with drama, especially if it involved boys, but she knew her new friend needed to talk, even if she said she didn’t want to. She looked around and breathed a sigh of relief when she noticed one of the custodians walking away from a nearby classroom with their cart of supplies. With that room having just been cleaned, it meant it wouldn’t be used for the rest of the day and would be a perfect place to have a nice private chat. “Come with me,” she insisted and grabbed Megan’s hand and pulled her into the empty room.
Once she made Megan sit down on the comfy chair at the professor’s desk, Karmi sat down on the desk herself. “Okay, both you and Hiro said that nothing happened only to immediately contradict yourselves. Obviously something did happen, and obviously you are both feeling upset about it,” she began. “But why? What did he do to you? Do I need to punish him?”
Megan shook her head. “No. He ... I...” she began, struggling to sort out her thoughts as well as her words. She took a deep breath to calm herself down a bit. “Hiro didn’t do anything wrong. Please don’t be mad at him. I may have overreacted.”
“Okay, but what exactly did happen?” Karmi asked, her voice full of sympathy and concern.
Megan let out a sigh. She didn’t particularly want to talk about this because of how embarrassed she felt, but perhaps it was for the best to get this off her chest. “Hiro...” she began, then corrected herself, “I messed up. The first day Hiro and his aunt were staying with us I thought I was alone and...” She paused, too embarrassed to say what happened next.
“And?” Karmi gently asked. A thought occurred to her and she couldn’t help but blush. She and Megan still didn’t know each other all that well so she was a little hesitant to say it, but lowered her voice to a whisper and asked, “He didn’t catch you ... masturbating, did he?”
Megan’s eyes went wide at the suggestion. “What? No! God, it would have been so much worse if he saw me doing that!” She then looked wide-eyed at the other girl, realising what she had just inadvertently confessed to doing. Despite Megan’s darker complexion, Karmi could clearly see her cheeks redden. “I mean, not that I, um...”
“Sorry, I didn’t mean to embarrass you,” Karmi said. “But it’s perfectly normal to, um, take matters into one’s own hands. Literally.” Not wanting her new friend to feel singled out, she added, “I do it too, you know. Every now and again.” She could hardly believe she had just said that out loud and her own face turned just as red as Megan’s, if not redder.
Megan’s blush continued, but curiosity got the better of her and she forgot some of her embarrassment. “Really?”
‘Oh well,’ Karmi thought. ‘It’s too late to back out now.’ She then nodded and said, “It’s no secret that I used to crush hard on Captain Cutie. After he saved my life that first time I started imagining ways I could thank him, um, personally.”
“And I’m guessing you don’t mean something like baking him a cake,” Megan said with a knowing grin.
Karmi returned the smile. “Yeah. Let me just say that the body pillow I have of him has been put to very good use.”
Megan took a moment to imagine just what that might entail. Karmi, naked, straddling a large pillow with Hiro in his super suit on it, rubbing herself over its surface, head thrown back in orgasm. Megan’s own experiments with self-pleasure weren’t nearly so intense but she could definitely see the appeal.
Karmi could tell what Mega was imagining. She blushed further but didn’t bother denying it. “You can’t tell Hiro that, okay?” she said. “I don’t want him thinking that I still pine after someone else.”
‘Oh, I don’t think he’d mind at all,’ Megan thought, grinning. Out loud she instead said, “Sure, your secret is safe with me.” She meant it too. “Um, if you don’t mind my asking, do you still think of Captain Cutie when you ... you know, or is it Hiro that you imagine?”
“S-speaking of Hiro, what was it that he caught you doing?” Karmi said, redirecting the conversation. She had embarrassed herself enough already and wasn’t about to make it worse by admitting to getting herself off to thoughts of her former enemy.
The girls’ mutual embarrassment did make Megan feel better, and now she felt much more comfortable sharing. In light of what Hiro could have seen, what had actually happened didn’t feel so bad any more. “Right,” she said, allowing Karmi to bypass her question. “After I had a shower I didn’t bother getting dressed to go to my room. And Hiro just so happened to be in the hallway.”
“And he saw...?”
“Me. In my birthday suit,” Megan admitted. “I had my eyes closed at the time so I had no idea he was there. He just confessed now, which is why I slapped him. But can you blame me? Do you have any idea how embarrassing it is to have someone see you naked?”
Karmi shook her head no, blushing heavily as she imagined herself in Megan’s place.
Megan gave the other girl an appraising look. “Well, it might not be so bad for you. I mean, you’re very pretty and if you and Hiro do get serious I imagine you’ll be showing him the goods before too long.”
Karmi’s ears turned red at the thought. “Whoa! Slow down there, sister!” she said, waving her hands in denial. “It’s way too soon to be thinking about something like that! We haven’t even kissed yet, so there’s no way I’d let him see me ... like that.”
“I guess fantasies don’t count, huh?” Megan added with a playful grin. The blushing silence she got in return made her smile even more. “Well, in my defense I didn’t let him see me either,” she pointed out. “He just was in the wrong place at the wrong time.”
“Wrong for you, maybe, but right for him,” Karmi said, trying to tease the other girl back. “I imagine that’s a sight he’s never going to forget.”
“Yeah, lucky him,” Megan said, somewhat sarcastically. “So are you saying you’re okay with him looking at other girls while they’re naked?”
Karmi shook her head. “No. But like you said, it was an accident. I’d be pretty mad at any guy if they were trying to spy on someone, regardless of their relationship status. But if it was indeed an accident...?” Karmi said, leaving the sentence unfinished. It wasn’t an accusation, per se, but the unspoken question was obvious.
“It definitely was,” Megan confirmed. There was no way she would have let Hiro see her nude on purpose. Not without flowers and chocolate first, she jokingly thought to herself.
“Then I don’t really see the harm in it. So long as it’s only looking,” Karmi stressed. “Though if you ever catch him trying to spy on you, promise to tell me right away so we can both kick his ass!” she added with a smile.
“You got yourself a deal,” Megan replied, laughing. She stood and the two girls started walking towards the classroom door. “Um, what about the reverse?” she suddenly asked.
Karmi stopped and turned to her. “What do you mean?”
“Well, Hiro and I do share a bathroom, and we’ve already had one accident. It stands to reason that others might happen too, and not just him seeing me. Would ... would you be upset with me if I happened to see him naked?”
Karmi blushed at the thought of Hiro standing naked in the shower with water cascading down his body.
When her mind’s eye reached his groin, and his imagined family jewels, her blush deepened as a surge of arousal hit, and she shook her head to banish the image and get herself under control. “Um, if it were truly an accident then no, I wouldn’t be upset,” she said, trying her best to steady her voice and hide her carnal feelings. “However, if you were to, um, inadvertently do something that results in such an ‘accident’, then...” She looked around the room once more to make sure they were still alone, then leaned in close to Megan whispered conspiratorially, “pics or it didn’t happen.”
Megan gasped and took a step back in shock. Despite her ability to read people fairly well, the very unexpected response and the playful smile Karmi wore left her unsure if the other girl was being serious or not. Either way, a second later both of them burst into giggles. “You better be careful,” Megan warned. “Don’t be surprised if some day soon I actually give you just what you asked for.”
“Asked for? What do you mean? I didn’t ask for anything,” Karmi said, playing innocent.
They giggled again as they left the classroom and made their way back to an anxiously waiting Hiro, discussing what they should do about his lack of honesty.
For his part, Hiro was pacing back and forth in his lab, wondering what he could do to make it up to Megan and now Karmi, apparently. He hadn’t decided on much beyond apologizing when the girls returned. Their expressions were flat and unreadable as they closed the door behind them, ensuring some privacy. Karmi opened her mouth to say something, but he held up a hand to forestall her. He then got down on his knees and brought his forehead to the ground, kowtowing to them. “I’m sorry,” he said.
“For what?” Megan asked, her voice neutral.
Hiro looked up at the two girls, unsure of how much he should say since he didn’t want to embarrass Megan any further by saying something private in front of Karmi.
“Karmi knows,” Megan told him. “You don’t need to tiptoe around anything.”
A quick glance at and nod from Karmi, and Hiro bowed once more, though not as low as before. “I’m sorry for seeing you naked.”
Had he been looking up at her, Hiro would have seen Megan blush at the reminder. Instead, all he heard was, “And?”
“And for not telling you,” he added.
“And?” added Karmi.
It took Hiro a second to think of what else Megan might be mad at him for, then he remembered “And for lying to you just now.”
Several long seconds of silence passed, of which Hiro dared not raise his head. The fact that there wasn’t another “and” was a good sign, he hoped, but the extended silence made him worry. Eventually he heard movement, and chanced a glance up. Megan had unexpectedly taken a kneeling position across from him and once she saw that he was looking, gave a bow herself.
“And I’m sorry too. For slapping you,” she said. “I overreacted and you didn’t deserve that.”
“It’s okay, really. It’s already forgotten,” he replied, glancing away. It was a little awkward to have her bow to him after what just happened, but more than that he had to look away or else he’d be staring down the neck of her shirt as she bent over. Considering that the girl he liked was right there and why he was in trouble in the first place he didn’t want to risk being accused of letting his eyes wander to somewhere they shouldn’t.
Karmi noticed his eyes shift and smiled appreciatively. “Okay, you two, that’s enough bowing. My knees are getting sore just looking at you,” she said. The others got up off the floor, then she added, “Saying sorry is all well and good, but there’s still the matter of what to do going forward.”
“Going forward?” Hiro asked.
“Yeah. We ought to know what to do when this sort of thing happens again.”
“Again? There is no ‘again’. I specifically asked to reorganise our bathroom schedule so something like that couldn’t happen any more.”
“And I’m sure Megan is very grateful to you for that. But the universe has a way of ... balancing out, as it were.”
At first Hiro was relieved that Karmi was not suggesting that he was hoping to catch Megan in other compromising situations, but then the real meaning of her words registered. He looked at Megan, who returned his look of worry with one that was both playful and predatory. He instinctively took a step back.
“Hold on just a second,” he said, holding up his hands defensively. “I’m not sure I’m comfortable where this conversation is going.”
“Oh? And where do you think it’s going?” Megan teased, making a quick but noticeable glance down at his crotch. Hiro blushed and took another step back, moving a nearby chair in between him and Megan. Both girls giggled at his behaviour.
“Oh relax, would you?” Karmi said. “All we’re saying is that accidents happen. Getting embarrassed is perfectly fine, but we want to avoid anyone getting angry or feeling like they have to lie. So to help prevent any more hurt feelings like what just happened with Megan, I propose that if ever you catch Megan in a similar situation, you tell her at the earliest opportunity.”
“I don’t like being embarrassed, but being lied to is worse,” Megan added.
Karmi nodded in agreement, then continued. “And after you’ve spoken to her, you will let me know as well.”
“Are you sure that’s a good idea?” Hiro asked. He could see the logic in Karmi’s words, but didn’t think that confessing to his potential girlfriend whenever he saw an up-skirt or down-blouse or whatever else was the best of ideas. No doubt telling her every time he saw something inappropriate, even if it was an accident, would only end up with him in some kind of trouble.
“I am,” Karmi said. “Provided you don’t go looking for opportunities to, um, look.”
Considering that he fully intended to do everything possible to not have any repeats with Megan, Hiro was more than willing to agree. However, he didn’t like how the two girls seemed to be teaming up to tease him and he felt that perhaps a little pushback was in order. It wouldn’t do to have them think they could walk all over him, after all. “You know, this proposal of yours feels kind of one-sided,” he said. “Like, why does it seem like the onus is all on me?”
“I’ve got no problems agreeing to it, too,” Megan said almost immediately. “If ever I happen to see you with your pants down, and I guess I do mean literally, I’ll make sure to tell you. Karmi too, of course.”
“And the same goes for me,” Karmi added. “Although I don’t live with you so I can’t see such things happening when I’m around.”
The fact that both girls agreed to this idea right away made Hiro feel like he had somehow been manoeuvred into a trap. ‘Well,’ he thought, ‘if I am trapped, I’m not going to be the only one caught.’ Out loud he said, “Okay then. If that’s what you want then I have something else to confess.”
“What? From when?” Megan asked, the air of confidence suddenly gone. For just a moment she thought that he had somehow seen her naked a second time already.
“Just now. When you bowed to me, I could totally see down the neck of your shirt,” Hiro said bluntly, though it took all of his effort to appear nonchalant. “Red’s a nice colour on you, by the way.” It was embarrassing to admit that he had seen down her shirt but if he had to admit to having seen, then he wanted her to be just as embarrassed for having been seen, if not more.
Megan quickly blushed. Red just so happened to be the colour of the bra she was wearing. She reflexively brought up a hand to her neckline, as if doing so now would somehow undo her accidental exposure. She normally wouldn’t have minded teasing Hiro with a little peek like that, but the revelation of him having seen so much more than that already had her feeling uncharacteristically bashful.
“I did look away as soon as I noticed,” Hiro pointed out.
“He did,” Karmi confirmed, giving him a gentle smile to show she approved of his actions.
Megan took a moment to try and get over her embarrassment through sheer force of will, and was mostly successful. With a determined look, she gave Hiro a grin that conveyed more confidence than she actually felt. “Well, I guess that means I’m behind by a score of two,” she said.
“Score? Since when was this a game?”
“Oh, it’s definitely a game. And I hate losing.”
Hiro wasn’t sure if Megan was threatening him or flirting with him, though if it was flirting he was pretty sure that Karmi ought to speak up and shut it down, even if it was just teasing. Instead, Karmi moved over next to the other girl and gave Hiro a playful grin. “Does your bathroom door have a lock?” she asked, a little too sweetly. The tilt of her head showed the question was for Megan, but she kept her eyes fixed on Hiro.
“It does,” Megan answered, likewise looking straight at Hiro while responding to Karmi. “But it’s just one of those simple locks that even a bobby pin can just pop open.”
Hiro gulped. He had the unshakable feeling that he’d have to take extra precautions if he didn’t want to find himself quickly losing this little game.Before things could get any worse his alarm went off, indicating it was time to head home. He and Megan said goodbye to Karmi and made their way home, and thankfully Megan stuck to mostly mundane topics along the way.
While Hiro was getting ready for bed, however, Megan poked her head into his room. “Goodnight Hiro. I’ll SEE you tomorrow.” While what she said was fairly innocuous, and had either of the adults overheard they would have thought nothing of it, her emphasis on ‘see’ had Hiro eyeing her suspiciously. She laughed at his look and left, leaving him to wonder what she was up to.
As he lay in bed waiting for sleep to come, he pulled out his phone and texted Karmi. “Hey,” he wrote, “sorry to be texting you so late, but are you sure you’re fine with that arrangement you and Megan came up with?”
“Yes. Why?” Karmi texted back a few seconds later. She must have already been on her phone to have responded so quickly.
“Well, Megan has all but admitted she’s going to try and spy on me tomorrow.”
“Then you’d best be on your guard 😉”
That was not quite the response Hiro was expecting. “Really? I thought our agreement was about accidents, not for doing things intentionally.”
“Don’t worry. She’s just teasing you,” Karmi replied. “I already had a talk with her about this and she knows where the line is.”
“Mind telling me where the line is ‘cause I really don’t know. I’m wondering if I have to wear a bathing suit when I shower tomorrow morning.”
“If you’re that worried, you can always just use the showers at the campus athletic centre,” Karmi pointed out.
That would be a solution, even if it was a little excessive. Perhaps Hiro was being too paranoid. It was clear Megan liked to tease but surely she wouldn’t actually go so far as to break into the bathroom while he was in the shower. And if he was being honest, Hiro was actually having a good time with all this despite the potential for embarrassment. Even though it was just a game, having a pretty girl ‘lusting’ after him did make him feel good. “No, I’m sure that won’t be necessary. Though I may rig the bathroom door with a trap, just to be sure 💣” He paused in thought, then added, “I’m kidding about the trap, by the way.” As convenient as texting was, it wasn’t great for conveying subtext or sarcasm and he wasn’t sure if his words came across as the joke they were meant to be.
“Yeah, I figured.”
“Well, I guess that’s all I wanted to ask. Thanks for hearing me out.”
“Any time. Good night, Hiro. I’ll see you tomorrow.”
Hiro knew it must just be coincidence, but the fact that Karmi just used the same words that Megan did made him blush. If it was her place that he was staying at, he just might have left the door unlocked. “Good night.”
The following morning Hiro went straight for the bathroom once he woke up. He was mostly sure that his time in the shower would go by without incident, but he still made sure the bathroom door was locked and that the small gap under the door was covered with a towel. Considering who her dad was, it wouldn’t surprise Hiro to find that Megan had access to any number of devices that would let her see through cracks in doors.
He thought he was safe when he finished the shower without any sign of someone trying to come in, but he got a very unpleasant surprise when he looked in the mirror. Written in the condensation that had built up from his shower was a message. “Better watch your back, Hiro!” it said, followed by a winky face and several hearts.
He immediately covered himself and looked around the room, fully expecting to see a smug Megan standing in a corner, watching him. After his quick look found nothing he quickly checked the door but saw no evidence of tampering there, so took a closer look at the message. Upon careful examination he noticed the message was actually written in a thin layer of something clear but a bit oily, probably a moisturiser of some kind, that he only now noticed because the water vapour wouldn’t stick there like it did with the rest of the mirror.
