My responses to these, if I have any:
Adria: I don't think Dzaan are naturally cross fertile but we have met a few half Dzaan.
Dzaan are naturally capable of crossbreeding with other races.
Anno/Syri: I am not sure if either of them is ready to be a parent. Kaede might be open to knocking up Anno. I am not sure if Syri has thought about knocking anyone up.
Correct, none of them are ready yet. As for each individual:
- Syri's waiting until she and Steele can settle down enough to raise the kids properly, with none of this adventuring stuff to interfere.
- Kaede is perfectly satisfied with just Kayla, but probably will wind up making a few more with Anno, especially if Steele's not willing to knock her up. I can't imagine she'd refuse to have kids with Steele, either. In either case, it'll have to wait until she's in a better place both financially and with regards to the Black Void.
- As implied by the above, Anno's definitely going to have kids some day, and I don't think she's particularly concerned over whether Kaede or Steele (or both!) is the sire.
Azra: I don't think we are having penetrative sex yet, plus she might consider herself a little old for more kids. So would need more content first.
Her initial plans were that she'd officially declare Steele to be her new stud after the third expedition, and that would lead to pregnancy content - there were even busts made for this. If someone were to pick her up again, I think it's likely they'll stick to those plans.
Dizzy: Might be past what she would consider breeding age. I haven't explored her crew content, I usually stick her with Bizzy.
She's certainly an older woman, but that wouldn't stop her if she wanted more kids. Given that she already has three grown-up children, it's entirely believable that she wouldn't want more, but the same could be said of Azra, so she could honestly go either way.
Gianna/Nova/Olympia/Tika: All machines. I would not be surprised if Gianna or maybe Olympia has artificial wombs, but I would prefer using Bridget for that.
When talking about Azra, Olympia actually admits to some level of jealousy of her due to her own inability to conceive children - and even mentions that she could get an aftermarket incubator if she wanted to experience pregnancy. That said, the jealousy seems to be of a more... curious nature, than an "I want to but can't" nature.
I'd also presume that if Olympia could get an incubator, Gianna also could.
Kase: Can already knock Steele up, but it registers as a generic pregnancy. Could use an expansion.
Agreed. From what I've heard, his relationship with Sam could also use some expansion - and maybe he could knock her up, as well? If I were writing a Kase expac, that's something I'd definitely include if I were allowed to.
Kiro: Definitely on contraceptives, but I believe she would be up for having a baby in her with someone she loves (ie Steele or her sister, since Paige doesn't have the equipment). She is too sexually active to risk knocking you up without tons of collateral pregnancies.
Possibly, especially after KiroQuest if she wasn't bimbofied, but like Anno and Syri, she'd almost certainly want more stable living conditions for the kids if that were the case. The same is probably also true for Penny, who you forgot to put on your list.
Also, you can convince Paige to get a cock, so she's also a potential sire for Kiro's kids.
Mitzi: Another prime candidate.
I have no idea how she'd react to getting pregnant, and I'm not confident in her ability to be a good mother. The same could be said of the bimbo versions of Kiro and Penny.
Paige: I don't recall her mentioning her thoughts on kids.
Nor do I, but IIRC B said that if she were to get married, she'd want it to be monogamous. As such, not really compatible with most Steeles in that regard; whether that would extend to having children, I have no idea.
Ramis: It's been a long time since I had sex with her, but I remember her preferring using her strap one on femboys then being penetrated.
No, she generally prefers being penetrated (both by masculine men and by femboys, though they both need to have at least an average-sized cock), and the whole strap-on thing was introduced to her by Steele.
Shekka: She can knock you up with a horse cock. Could use some expansion in the Nursery with her kids.
Like with Kase, I agree her being a sire could use some expansion - especially since the email she sends you makes her seem so excited about it.
