Goddammit you can feel the emotion, the conflict and the sheer, pure Love Sunset has for Rainbow. It goes way beyond passion or lust, into wanting what's best for her Omega, no matter how much it hurts. Because she doesn't let herself believe that Rainbow loves her back, or that she could be happy as her Bitch.

I just hope they end up happy in the end

Ah, thanks; I was wondering what the balance was between the two. :)

...Ah. Hm. "Don't think about it too hard" is a bit of a problem for me here, unfortunately; I want to figure this out! And that this story seemed to be taking the biology seriously was (is?) one of the attractions for me.
Well...
We have a close example from male humans (among many other species) of reproductive and liquid waste channels being run through the same orifice, and monotremes provide a still-mammalian example of reproductive, liquid waste, and solid waste channels all running through the same orifice. During delivery through the solid-reproductive orifice, the offspring could potentially be protect by the same sort of sac-I-forget-the-name-of-and-don't-presently-have-time-to-look-up as equine foals. Presumably the setup of the uterus is approximately the same for both "male" and "female" configurations, with only the opening changing, though there might be some sort of lack or reduction of auxiliary equipment (not sure just what that'd be, not an expert in the field and, again, currently in a bit of a hurry) contributing to reduced "male" fertility (have to make room for the male equipment, though I suspect some parts may have roles in both). Though pelvis configuration may be a concern. Possibly--
...Wait, you said there were "'male'" Omegas (Also, why is that capitalized?)? And they also have the extremely high fertility? Shoot, there goes one idea... I guess "females" might still have an advantage in fewer resources spent on male genitalia, but...
Argh. Have to admit, my motivation for continuing with the story's dropped heavily. Quite possibly temporary mood effect (and I certainly don't have time for the new chapter right now either way), and I'm interested in other aspects of it (and already invested), but I do hope there's some way to work out the biology aspect (that I'm just not seeing at the moment, because hurry).

(Oh and I should probably still mention that while thinking of the above it also occurred to me that that "mostly" might end up applying to Rainbow and Sunset in the plot, but I've kind of lost the enthusiasm I had for mentioning that when I still thought I was working the system out. (Again, quite possibly also temporary.) But I also should really be moving on to the next thing in the queue anyway.)

(Oh, quick check: Did a wizard do it (or equivalent)? Because that, while less satisfying in some ways, would certainly explain it. Why does the system work like this? For the same reason that bear has an owl's head; there's little to no interesting evolutionary physical and psychological history, but at least we have a plausible route for such a thing arising: some guy with a wand thought it'd be cool.
...Actually, I'm not sure how much better that'd actually be, at least given how interested I was before, but, again, likely temporary mood effects and also I really need to be moving on now, sorry if this is getting a bit incoherent. :))

(Got a bit of extra time, and I also wanted to get this question(ish thing?) in.)
(My main issue is... if "male" omegas are just as fertile as "female" omegas... Why exactly do "females" exist in this species? Sure, the "female" biology includes mammary glands, very important for mammals, but is it really that much more expensive to just stick those on a "male"? Sure, the "male" omegas, as I recall, are vanishingly unlikely to sire offspring, but if the only thing they lack there is viable testicles, well, unless I'm much mistaken, testicles are basically an add-on compared to the more complex and extensive systems involved in bringing a child to term. Again, is it really that much more expensive to add that one last bit to the already present male genitalia? Of course, the species might still have different fertility groups within it or something, but I'd expect them to be variants off the "male" model.)

(Oh, yes, and I see a comment's been left on Chapter 4, though I've fortunately been able to avoid reading it so far. Please don't reply to my comments here in the same one as any reply to that, or it'll be harder for me to isolate them (which might already be tricky if short comments get mixed together). I'm also not sure when I'll get to the new chapter, given I have at least one more urgent (due to its location) update in queue today and hours more before I can start on that queue (and I'm kind of torn between wanting to put this chapter right after that, so I can get it done and be more free in looking at the comments (and maybe even have some new data) and wanting to hold off on it until this is resolved so that my experience of the chapter won't run the risk of being tainted by this); sorry about the inconvenience.
I suppose we could also take this to PMs, actually, which would perhaps be better in a variety of ways but would mean that other people wouldn't be able to see any solution we came up with, or you revealed, unless it was pasted in or something.)

Sent you a PM if you want to continue the discussion.

10112823
I got it; thanks. :)

10112718
Yeah, because of how their relationship started, (and the fact that Sunset is a gay self-sabotaging disaster) all Sunset can see is how she has been taking advantage of Rainbow.

Considering this is both the most eww and at the same time one of the most intriguing parts of the universe, taking it out of the comments seems kinda excluding to other readers, even if it unclogs the section for others.

I'd honestly recommend the True Hermaphrodite approach to the rare male Omegas and female Alphas, if they still exist. That keeps the basal characteristics of "Alphas can sire and Omegas can bear" without going into surreally complex biology for the sake of fetishes. Unless that's your thing.

It could link nicely with the interchanging Betas and multi-species origin.

Don't read this next one yet Reese, it pertains to the 4th chapter.

One can hope Fluttershy's Kindness can help her realise her mistake

nice work

(I see there's a reply to my comment, but my attempt to look down at it first did seem to indicate a too-high chance of spoilers interlaced, even though I noticed Neece themself nicely put their spoilery bit behind a marked tag. :)
But it's not everyone's responsibility to follow the conversation and do that, so, given the line's now clear for me to got through the chapter and it's not that long, I decided to do that first.)

Well, bit of a mess there. Sunset's unhappy, Rainbow's unhappy, Applejack is currently no longer unhappy but I doubt that's going to last long once she takes in Rainbow's current state, and Fluttershy is presumably currently blissfully unaware of what she's now getting dragged into.
And it's quite likely to get worse before it gets better.
I'm interested to see what happens next. :D

Right, and on to the comments.

"I just hope they end up happy in the end "
I hope so too.

10113074
Thanks again for the spoiler tag. :)
And it looks like I might have been able to read these comments earlier after all, but, well, didn't know that then.
Anyway:
Aye, maybe a blog post or something on it would be useful, linked in the description? Up to I-A-M, of course, but that way the people who are interested could find out without having to dig through the comments (or at least possibly through digging through more on-topic comments that might appear on the blog post), while people who don't want to see it here don't have to.

and re the spoiler-tagged:
Ah, good point. If anyone was going to meet this with understanding and trying to help even after finding out what Sunset dragged them into and why she did...

As someone who is a little sick of reading about societal homophobia as a point of drama in romance, this world has a kind of interesting twist to it.

I know I'm supposed to root for them to be together, and I am, but at the same time I'm still unsure about Rainbow Dash's psychological state. She seems happy but can she accept this in a long-term situation? Is she psychologically stable? How is her self-esteem? Would she be able to accept her friends and others finding out the nature of her relationship? These are important questions for any relationship. Whether straight, gay or really gay like this one.

So it is important to note there are societal and psychological factors in this world that don’t exist in our world.

As for accepting things, the one who’s really having trouble accepting the situation isn’t Rainbow, it’s Sunset. And believe me, I’ll go into a lot of it in the story. We’re closing in on the endgame.

Ah man I was hoping to see sunset and AJ throw some hands
