I took deep breaths as I lay on my back and looked at the ceiling. What had just happened was starting to sink in, and two thoughts were going through my head.

First, Why in the hell did I just do that?

Second, and slightly more tongue-in-cheek, Why in the hell haven't I done this sooner?

I titled my head up to look down the length of the bed. On my left lying against me and sleeping peacefully was my girlfriend Rin, her state of undress indicative of what we were just doing. This was certainly not anything out of the ordinary.

On my right however was her Servant Saber, also naked and sleeping soundly. This was most certainly out of the ordinary.

This… this sort of thing isn't supposed to happen. It's like the plot of one of those juvenile harem animes, although why it would chose now of all times to spring this on me would probably be a sign of poor writing anyway. The War ended, I started dating Rin in earnest, and Saber was just our close friend and comrade. It was never… like that. Until now anyway.

I gave a small sigh and sat up, pushing myself back to lean against the back board of our bed. Rin murmured a little but remained asleep. Saber on the other hand opened her eyes and propped herself up to look at me. Her face was flushed for a number of different reasons, but at the moment I could tell there was no small amount of embarrassment. "Good morning." She said, looking off to the side.

"… Morning." I replied softly. I felt some unease at looking at her, because I knew that she considered what happened last night to be her fault. She had been feeling down for the past few weeks, and while I had asked her about it a few times, she had always brushed it off as nothing. Once I had thought I had heard her mutter something along the lines of "lonely", but she denied it. I dismissed it myself because it didn't make sense. Rin and I were around her all the time. How could she be feeling lonely?

Once again, hindsight made me feel like an idiot.

Saber had always professed to not being interested in relationships, but it seemed that the two or so years she had spent with us may have changed her mind on the matter. This had come to a head last night when Rin had got word that funding for her latest project had been approved and this led to a party being thrown. Saber had a few drinks, but it was difficult to tell how affected she was. I was… less than sober. Rin was completely hammered, and that's when she gets a little handsy.

It was no secret that Rin happened to swing both ways, and she had on more than one occasion flirted with Saber. She was just tensing her though, as Saber would always get flustered and embarrassed about it (it was kind of funny). So it was no surprise when the night started winding down and she started leading me into the bedroom, she also dragged Saber in as well just to tease her a bit.

I'm pretty sure she wasn't expecting Saber to actually… well… join in.

Saber pulled herself up to a sitting position, still looking away from me. "I am… sorry. It was wrong of me to take advantage of you two in that state. I should go."

She made to get up, but as she did I reached out to grab her hand and pull her closer to me. This caused her to let out a small yelp of surprise as she tumbled into me and she found herself lying against my torso. "Don't say that." I said. "You did nothing wrong."

She looked confused, but didn't move away from me. "But- but I intruded on your relationship with Rin. I knew she didn't actually want me to…" she trailed off.

I gave a small shrug. "If you're really worried about her being mad, you could try doing that thing with your tongue she seemed to enjoy."

Saber's face went beat red at this comment and she buried her face in my chest. I couldn't help but chuckle at this. Part of me felt that I was talking this way less seriously than I should have, but considering the number of endorphins going through me at the time I felt incredibly relaxed. I was never exactly very focused on sex (which was not to say that I didn't enjoy it), but I think I was starting to see why it seemed to be on every other guy's mind all the time.

After a few moments of silence, she glanced up at me. "And what about you? Aren't you mad at me for this…"

That did wipe the smile from my face. Regardless of however Rin might feel about this when she woke up, there was still the question about how I felt. True, under general circumstances I would be rather anger with a woman if she took advantage of when I was drunk to sleep with me, but this… "Saber, I wasn't that drunk."

"…What do you mean?"

"I mean I could have stopped you." I gave a sigh and scratched my head. "I let it happen. Probably because some part of me wanted it to happen."

Saber looked at me before giving a grunt. "I did not know that you wanted such things, Shirou. Then again, most men in this age seem to exalt the idea of having two women at the same time, so I suppose it is not unexpected."

"No, no, not that." I said shaking my head. "I didn't mean with the both of you. I meant… you. I wanted to… be with you."

Back when the War had first started, there had always been a connection between Saber and I. As the days passed, we became closer, and things seemed to be heading in direction where our relationship might have become something more. Then Caster stole my Command Seals and took her away from me. Rin and I ended up getting together after that, and then we got Saber back as well. Ostensibly, nothing happen between the two of us after that. Expect that wasn't quite true. There had been moments, when it had been the two of us alone and close, that I had felt what I did during those first days of the War for her. In those moments, I sometimes wondered where things might have gone with her.

Moments like the current one, with Saber pressed against me, her eyes wide from what I had just said before a smile crossed her face. "I missed you." She whispered as she moved her face closer to mine, moving so that she was now straddling my lap.

"I missed you too." I replied before I kissed her deeply.

I'm not sure how long we stayed like that, but eventually Saber pulled back and her smile turned sad. "This… won't work, will it?"

I felt despondent as I knew what she meant. If I still had feelings for Saber, that would make things complicated between me a Rin to say the least. And after tonight, we couldn't just go back to way things were, especial considering how we all lived in close proximity with each other. "I don't know."

We sat in silence for a while before a stir and a small moan brought our attention to Rin, who was now waking up. She pulled herself up and rubbed the back of her head before glancing at me and Saber. "Soooo," she drew out as the two of us shifted uncomfortably. "That happened."

"Uh, yeah." I said lamely.

"You're looking awfully comfortable." She said with an arched eyebrow.

Saber shifted in my lap. "Rin, I must apologize for my conduct last night. I let my emotions get the better of me and did something unbecoming."

"You did something alright." Rin said wirily before giving a sigh. "I guess something like this was bound to happen sooner or later. I certainly didn't make it easier on you."

Saber blinked. "You are both being awful calm about this considering what just happened."

Rin shrugged. "I mean, if you just went and seduced Shirou behind my back, yeah, I'd be pretty pissed, but I started this mess. If you want we can just leave it at this, that's fine."

Saber paused before she looked up at me, and I grimaced and said "I don't think we can do that."

Rin frowned. "What do you mean?"

I glanced away. "I… still have feeling for Saber. And she for me. I still care for you of course, it's just that…" I trailed off, not sure where to go from there.

"Really." Rin said flatly before looking at Saber. "Is this true?"

Saber looked guilty, but she wrapped her arms around my neck. "Yes. I'm sorry. It would be best if I removed myself from you two for a while"

Rin was taken aback by this. "Why would you do that?"

"Because we can't all just pretend nothing happened." I said. "I don't know how to deal with caring for both of you like this, but I know that there'll be problems it we just try to pretend nothing happened. The relationship the three of us has can't go back to the way it was, no matter how much we want it to."

Rin stared at us for a moment before sighing again and shaking her head. "Jeez, you two are so dramatic about things. But I guess you're right. Things do have to change. However, I know what to do."

She drew herself up into the pose she normally uses when she has an important declaration. "I am starting a harem!"

"What?!" Saber and I exclaimed.

She continued. "I have been giving it some thought, and it's only natural that someone of my status to have multiple partners. And as I can't always be around, it is only natural for those of my harem to find comfort in each other. Besides, it's much less depressing than what you think is the 'right' or 'responsible' thing to do." She said with finger quotes.

I looked at my girlfriend completely shocked. "Rin you can't possibly be serious."

"I am serious. I have decided it, so it shall be so."

"But you can't just sweep this under the rug-"

"Too bad. I just did."

"But-"

"Shirou, why are you arguing with me when I'm letting you sleep with two women?"

I paused with my mouth open before it clicked shut. Maybe it was the endorphins, maybe it was the way Saber was looking up at me, or maybe it was because memories of last night were still floating favorably through my head. Whatever it was, I felt my desire to argue with her on this waning. "Well… I guess we can give it a shot." I said sheepishly.

"Th-this is most improper!" Saber said.

"I know." Rin said with a wicked grin. "That just makes it kinkier." She then move close to the two of us and pressed herself against Saber. The blonde eeped at she suddenly found herself pressed between the two of use. "Now, seeing as how you never actually got any in your last life, we have a lot of catching up to do." Rin tone became low and husky, and her hands began drifting to certain places.

Things got a little hot after that.
