NOTE: This is the Taboo version of Innocent Devil's Harem, where Serenity is Kai's adoptive sister, and he refers to her as such. I've had quite a few people request that I upload this version again, so I decided to do so.

This version also later has HOT taboo relationships happening between other characters that are significantly less steamy in the non-taboo version compared to this one.

Hope you enjoy!

- CHAPTER 17 -

After my older sister's agreement to 'share me' with my girlfriend -- technically fiancé, since we'd sort of just jumped straight into the deep end -- the three of us all fell into a short awkward silence, before I cleared my throat and excused myself to take a shower, so we could head to the bank. Normally, under different circumstances, I might have used the opportunity to jerk one out while I had the chance, to ensure I was level-headed while out in public, but right now I was far from horny.

Instead, I was nervous as fuck. Scared too, if I was being honest.

Because what if my older sister changed her mind?

I mean, all this just seemed too good to be true, and I felt like at any moment Serenity might slam on the figurative brakes and suggest she couldn't go through with it. But then again, I was almost glad we weren't crossing the line physically first, like we almost did earlier that morning, because it would really hurt to go too far, only for her to then change her mind after we'd fucked.

Or after we'd at least done oral, or something.

So I knew it was better to let her sit on the idea for a while, maybe sleep on it too, before we let it go beyond where we currently were.

However, I also had another problem.

Being this nervous made it difficult to look normal, prompting me to realize I needed to change my mindset and focus on something else. Thankfully, I was able to do it, but it was only through letting the lingering depression to set in that I managed.

A somberness that came with the fear of being let down.

When I finally got out of the shower, seeing that Gabriella had changed into one of Serenity's black t-shirts, which almost didn't fit her because of how busty my girlfriend was, both of them knew something was up. However, when they asked, I just shook my head.

"We ready?" I wondered simply.

They both hesitated before nodding, following me down the stairs as I went to go collect my wallet, phone, and keys, before heading out the door. Similarly, my sister grabbed her black leather purse and followed after us. Outside, when I opened the driver's door of my silver car to climb in, I was a little surprised when Gabriella offered for my sister to sit up front with me, only for her to decline and say that she could sit up front.

Gabriella hesitated then, before looking at me. "Kai, which would be easier on you?"

That gave Serenity pause, speaking up before I could answer. "Wait, are you worried about him transforming, or something?"

Gabriella nodded. "Yeah, that's part of it. I just want everything to go smoothly, and I'm pretty sure it's a little stressful for him to keep it together when he's around me. Plus, I really don't mind taking the backseat, although I admit I'm not sure if it would help."

I finally spoke up. "If you really don't mind Gabriella, it would probably be a little easier."

Really, I just kind of wanted my sister to be at my side.

My girlfriend focused on me, nodding confidently. "It really is fine, Kai," she said, moving to the other side to climb into the back. My older sister met my gaze for a second, before giving me a tiny sympathetic smile and following suit, popping open the passenger's side door to climb in.

Once we were all buckled, and I began backing the car up, Serenity glanced back at Gabriella to give her a similar smile, glancing down briefly before turning her head partway.

She then froze solid, looking back and down a second time.

"What is that?" Serenity asked seriously, her deep brown eyes wide.

I was just in the middle of stopping to shift into drive, glancing back myself, realizing that Gabriella had her hands on her knees, a brand-new engagement ring in plain sight on her finger.

Serenity quickly looked back at me before Gabriella could formulate a response.

"Wait, Kai, you already asked her to marry you? You're engaged?"

"Sorry," Gabriella finally blurted out. "I know it's fast, but I've never been so sure about someone before."

Serenity stared at her in disbelief. "Okay, I get it, but you guys just started dating!"

I took a deep breath, pushing on the gas to begin heading down the driveway. "We can make another trip to the jewelry store," I said quietly. "I'll get you anything you want, sis."

She gawked at me, putting her hand on my arm. "Wait, stop."

I looked at her in confusion, slowing down about a dozen feet from the road. "What?" I asked seriously.

She took a deep breath, taking her hand back as she glanced forward at the gravel driveway. "Kai..." She sighed, focusing on me, her tone somber. "First of all, you don't need to rush all this. It's okay to take things slower. And second, you can't marry two people Kai."

"I disagree," Gabriella chimed in, causing us both to look back at her, prompting her to elaborate. "I mean, obviously he can't marry two people legally, but what really is marriage? Think about how they did it thousands of years ago. Nowadays you just have to go to the courthouse and sign a piece of paper, but back then they didn't have that." She paused, only to repeat her first question. "So what really is marriage?"

I turned forward to think about it, deciding to press on the gas again, while my sister kept her gaze on me as she considered it.

After a minute, once we were on the road, my sister finally spoke up. "I guess..." She sighed. "I guess you have a point. Marriage boils down to a lifelong commitment." She glanced back at Gabriella. "And really the reason why the government doesn't allow someone to marry multiple people is for tax reasons, since people could abuse the tax laws that way."

"Didn't know that was a part of it," Gabriella admitted. "But that's exactly what I'm saying. Honestly, I already feel like I'm married to Kai." She scoffed. "I mean, what's signing a piece of paper going to do? We could have easily done that yesterday too. And it's not going to change how I feel, whether we do or don't. Not to mention, someone could just as easily sign when they didn't really have their heart in it."

Serenity took a deep breath, finally sitting forward in her seat. "Well, I don't think I could wear a ring," she admitted. "I'd get too many questions at work about who the guy was."

I spoke up again. "I could get you something more simple if you want," I offered, sincerely desperate to take that step with her -- to make it feel like this was really going to happen, instead of being afraid she'd change her mind. "And you could wear it on your right hand," I added.

"Or just your middle finger on your left hand," Gabriella said in agreement. "Whatever works best for you."

Serenity sighed heavily. "This is all just so fast. I honestly can't even believe I'm seriously considering it."

"Considering it?" I repeated, my depression obvious in my voice.

My sister focused on me in surprise, before seeming somber herself. "Kai, it's not that I don't want to. It's just a really big deal. Like, I could lose my job if people found out, even if we technically aren't doing anything illegal. And even if I didn't lose my job, I'd lose all respect from my coworkers. No doubt the guys at work would probably start treating me like a slut." She scowled then, clearly frustrated at the idea. "No doubt I'd get under-the-breath comments about why I won't sleep with them if I'm so slutty that I'd sleep with my own brother."

"Isn't that harassment though?" I asked seriously.

She nodded with a frown. "Of course it is. But that won't stop them from doing it and denying it later." She scoffed. "They would never let themselves be overheard. And while I'd like to think that most of the guys I work with are decent, I've seen signs that it might turn out like that if they found out. They'd at least call me a slut for sure."

"You're not a slut," Gabriella said firmly. "And no one has to know," she added. "Besides, it's not like you're going to stop being his sister just because you become more romantically involved. Like, he's still your little brother. That will always be your relationship, whether you're married or not. And whether it's recognized by the government or not."

Serenity shook her head in disbelief, focusing straight ahead. "Gabriella, I really don't understand why you're okay with this. I mean, how are we even supposed to live our lives from now on? Like, are you wanting to move in? And how do we do sleeping arrangements?"

When Gabriella didn't respond right away, my sister glanced back at her.

My girlfriend shrugged. "It's a lot to consider," she agreed. "And honestly, I wouldn't mind moving in. I'll even pay rent if you want. But I'd rather us all be in this together, and figure it out together, instead of making sure it's 'easy enough' before making it official."

My sister faced forward again, mumbling, "I wouldn't make you pay rent," under her breath. She was then quiet for a few minutes, glancing at me. "I guess let's stop someplace so I can go in and get my ring sized, and then go someplace else so you can pick out a ring."

"Really?" I said hopefully.

She nodded, seeming more confident now, her tone gentle. "Yeah, really."

"But what if you don't like what I get? Are you sure you don't want to at least take pictures or something to give me an idea?"

She shook her head. "I already feel uneasy about the possibility of being seen by someone I know, even if it's unlikely. I'd rather just do it quick." She then abruptly focused on me, her expression apologetic. "And I'll love anything you get me. Just nothing too flashy. Like, maybe even just go for a simple wedding band."

I pursed my lips as I considered that. "Maybe I could get you something a little nicer, and you could just say you got a family ring cleaned or something."

Serenity was pensive. "Yeah, actually that could work. I could say it was grandma's old ring, and if I'm wearing it on my middle finger, then I don't think anyone would assume it was an engagement ring." She focused on me again. "I would still prefer it not be too flashy though. Really, I don't mind. Simple is better."

"What about a wedding band that has small diamonds all around it?" I wondered, recalling seeing a few such rings at the store when we got Gabriella's.

Serenity thought about it for a second. "Yeah, that could work. I've seen girls wear rings like that on their middle, index fingers, and even thumbs before. And if someone realizes it's a wedding band, then I still have the family heirloom excuse."

"Sounds good," I replied, feeling sincerely relieved now.

"Is this stressing you out?" my sister asked quietly, sounding a little sad.

I sighed, glancing at her, deciding to be honest. "You potentially changing your mind is stressful. Really stressful."

My sister gave me a sympathetic look, turning her head toward the road for a few seconds, before focusing on me again. "I really think we should take this slow, Kai. It's a big change." She took a deep breath. "But I won't change my mind. I think we're past that point now. I mean, even if I did change my mind, nothing is going to be the same again."

"Promise?" I whispered.

"Promise," she said more firmly. "I love you, Kai. More than anything." She sighed. "And I guess if I'm being honest, this is what I want too. I think it's why I decided not to date. Sure, I told myself that I just wanted to focus on making sure your life was stable -- to make sure you had all my attention..." She sighed. "But I think deep down I felt like you were enough for me, even if we always remained just normal brother and sister. I was fine with never being with anyone."

"Me too," I whispered, only to clear my throat. "Well, that was the plan until I met Gabriella, and even then, I wasn't planning on starting anything with her." I sighed. "But she found out my secret, and was okay with it." I glanced back at her. "Not that I'd want someone else," I added, speaking to my girlfriend now. "Obviously, you know you're amazing."

Gabriella nodded, giving me a small smile.

I sighed, glancing at my sister again. "So, just wondering -- and I know this is kind of random -- but does that mean you weren't attracted to me?"

She frowned. "Kai, being attracted to my little brother is kind of a big deal, whether we're related or not. So no, I wasn't thinking about you like that. Although..." Her voice trailed off, as she looked up at me with a grimace. "I did buy those pajamas with you in mind...even if I felt really horrible afterward..."

"Which pajamas?" Gabriella wondered.

Serenity turned to look at her. "The ones I was letting you wear."

"Oh," she said in surprise, only to look apologetic. "I'm sorry. I would have picked something different if I'd known."

My sister shook her head. "I wasn't planning on wearing them. And by the sound of it, if I had worn them, then he would have avoided me."

"Yeah, probably," I admitted.

"Why Kai?" she abruptly asked. "Seriously, why keep this from me? Why did you think I would reject you?"

I took a deep breath and let it out slowly. "Honestly? Because you always called me your little angel...and I look like a devil."

"Oh Kai," she whispered, tears abruptly appearing in her chocolate brown eyes. "I'm so sorry, I didn't mean..." Her voice chocked up. "Kai, you are my little angel, no matter how you look."

"I fully agree," Gabriella chimed in. "We talked about this, Kai. It's not what you look like, it's what's in your heart."

I took another deep breath and let it out slowly, reaching over to rest my hand on my sister's forearm. She immediately rested her thin fingers on top of mine. "I know," I whispered, glancing at Gabriella in the rearview mirror, still speaking to Serenity. "I'm just saying that I was sincerely worried you would reject me if you ever found out." I focused on my sister. "And I couldn't lose you. I can't lose you."

Serenity nodded, squeezing some tears out of her eyes before sniffling. "I'd never reject you. I love you, no matter how you look, or even if you really are a devil of some kind. I still love you no matter what."

I sighed with a nod. "Thanks," I whispered sincerely.

She let go of my hand then, pulling her arm away as she reached up to wipe her eyes. I, likewise, put my hand back on the steering wheel, not wanting to overdo it on the physical touch right now, though I wasn't at all in danger of turning gray. It was more like, I didn't want my sister to become uncomfortable with me being too touchy.

Essentially, I was taking her advice to take things slow.

We were all quiet for a few minutes before Gabriella broke the silence.

"So what are we doing at the bank?" she wondered. "I didn't want to be rude, but was kind of curious."

Serenity took a deep breath, answering on my behalf. "Umm, our parents left him something, and he wasn't allowed to withdraw it until he turned eighteen. I'd forgotten all about it, but then randomly remembered this morning."

"Oh." Gabriella paused. "Any idea what it is?"

"Nope," Serenity replied. "Not a clue. Probably not money, but really could be almost anything else."

I frowned at that. "Part of me hopes it's related to my biological parents, just because it would be nice to have an idea of where I came from." I leaned back more into my seat. "But part of me also hopes it's not."

"Why is that?" Serenity asked seriously.

I grimaced, glancing at her from the corner of my eye. "Because you're my family. As were our parents. I don't want to become too interested in whoever gave me up. Honestly, even if I had an entire family out there, I don't think I'd want anything to do with them. They didn't raise me. They didn't love me. And they weren't there for me."

Serenity frowned, only nodding in understanding instead of responding.

We were all quiet as I navigated through the city, drawing closer to the specific branch where the safety deposit box was waiting for me.

Gabriella spoke up again as I was pulling on the appropriate street. "You know, I just want to say, that this is really nice."

My sister looked back at her, while I glanced at her in the rearview mirror, prompting her to elaborate.

"I mean, I don't want to speak too soon, since I know this has all happened really fast. But I'm really happy to be in this relationship with you both."

"Oh," my sister said in surprise, seeming a little hesitant. "I hadn't really thought of it like that," she admitted quietly.

Gabriella continued. "Well, I just feel like we're all family now, a team of three, ready to tackle whatever life throws at us." She laughed then, though there wasn't much humor in it, her expression dropping. "Honestly, Serenity before I met you, I was getting kind of lonely. Not to the point that I was planning to try looking for someone to date, but I just don't feel like I fit in with most people." She sighed. "Part of the problem is that a lot of the people who want to be friends with me are either shallow, or they eventually get jealous of my appearance, especially if their boyfriends start showing interest, or something. Always something." She smiled then, refocusing on Serenity. "So thanks. For being the perfect friend, and for agreeing to be a part of this."

My sister nodded slowly, not seeming to know how to respond. She then frowned, her voice quiet. "You know, I haven't really thought much about how this 'sharing' thing is going to work. We should probably discuss that later," she commented, glancing forward to see that I was pulling into the bank parking lot. "Once we're done here," she added.

The bank was a little busy, given that it was a Saturday, though most of the vehicles where waiting in the drive-thru, with only a few actually parked.

"Sure," Gabriella agreed, garnering my sister's attention again. "And I'm fine with taking the time to work things out. We probably won't completely agree on how we'd like things to be, so I think it's important to keep an open mind on ideas and compromise where we're willing."

Unexpectedly, I recalled that Gabriella actually had a bit of a crush on my sister, suddenly wondering if that was what she was referring to. It wasn't necessarily that I'd forgotten, but I'd been so focused on my sister possibly changing her mind that I hadn't even thought about it. However, the idea was affecting me now.

"Shit," I hissed, gray already peeking out of my shirt collar.

"Kai?" Serenity said in alarm. "What's wrong?"

"Different subject please," I managed through my teeth, trying to keep my mind focused on parking.

"Oh, I'm sorry," Gabriella exclaimed sincerely. "Umm, umm, fuzzy pickles?"

I put the car in park, turning around to look at her in confusion. "What?"

She shrugged. "Fuzzy pickles. It's random. Did it help?"

I sighed heavily, sitting forward again, trying to focus on the task at hand. "Umm, yeah, I guess it did."

"Cool," Gabriella said cheerfully. "Then let's go in and find out what's in the box! Err, or the vault, or whatever its in."
