Is this obedience turning him on?  Yes it is, apparently, and furthermore his mind feels blank if he tries to figure out what else to talk to her about, so.  "You're allowed to start pestering me for sex again, by the way, since it's now morning.  No promises, of course, but you're allowed to try."

"Before yesterday turned out so eventful I was planning to show you what I got from the fancy Ostenso sex shop! And maybe invite you to come with me sometime but that's looking less likely, now. Maybe they can bring a selection to us."

"Well that sounds promising.  What new outfits or toys have I unlocked after our latest relationship progress?"

"I actually bought this outfit there! Should I tell you why they sell it at a sex shop not a normal tailors' or would you rather experiment."

"Now that's the dath ilani equivalent of asking a duke's son if he's too scared to go rhinoceros racing."

Experimentation follows.

The experiment is a success.  More resources are allocated to following up on these discoveries.

...this scientific investigation might possibly be threatening to get a little out of control and investigate subject matters that could perhaps be regarded as dangerous without a verified sufficient level of safety precautions.

Keltham accordingly restrains himself, but this is going to be pretty darned visible as a fact if you have Carissa's Sense Motive opposing what passes for Keltham's Bluff.

Carissa's mostly playing by intuition, lately, on a moment by moment basis, but she's aware that most of the point of seducing people for strategic reasons is that you can get strategic concessions out of them when their judgment is compromised. And also that dath ilan would definitely know this and advise their kids against it. So, we'll see who is better at this, Cheliax or dath ilan. 

She pulls herself away, sits cross-legged, folds her hands, tries to look - like she's trying hard not to say anything, like she's sad and not quite pretending otherwise but certainly not trying to put it in his way -

Keltham attempts to roll his Sense Cognitive Background State, devises a guess.

"Uh... if I trust my ability to read you, you look like somebody with a problem she'd usually and normally hide because that's what normal people in Golarion do in this situation, but you remembered that I asked you to err on the side of a lot more visibility, and now you're wobbling between that request and the reason why a normal person would usually hide that."

"I won't ask followup questions until I've either been told my current guess is wrong, or I've received some indication from you that you've reached your own estimate, using the information you have and I don't, that it is safe for me to inquire further."

Done, flaming shit that was hard to phrase without asking her to make a decision instead of him.  If this doesn't rapidly get easier with practice, Keltham is going to use his Unilateral Relationship Decisions Power to metadecide that he gets to ask Carissa to decide things ever.

"I think maybe people would hide this in dath ilan too, actually? On the principle that - uh, it seems wildly more important than not pressuring people into sex. But your orders take precedence. I think. If I calculated that wrong, well, probably we will calculate lots of things wrong at first."

"I need an explicit statement of your guess, using the information you have that I don't, that it's okay for me to ask more questions; I have no idea what you're potentially protecting me from right now, or what costs there are to my knowing something that's supposed to be unknown to me or even just illegible."

"It is fine for you to ask more questions!"

There's a very distinct ouch of realizing that he may have pressed her too hard, just then, to be legible and not subtle, when on the meta-level discussing safety.  But - she'll survive, she promised him that.

"Kay.  What's wrong?"

"You think that there's a - substantial chance, not a large one, but one worth planning around, that I am actually lying to you about having reliable contraception and planning to, I guess, get pregnant and then run off before anyone notices to some country where I wouldn't be legally obliged to have an abortion. And. I understand why the chance of that doesn't have to be very large to be very important to you. And I understand that you don't have much reason to trust me, though I and I think your god have been trying to give you some. And I understand that none of that matters and you can have the stupidest reason in the world and it's fine, it's your choice, you can have whatever you want from me and it doesn't have to be -

....but it does make me sad. And I don't see why you'd believe that, it's not - more information - but - but it does make me sad. Is all. Now you have all the information that I have."

"...and, uh, I remain very uncertain if you actually meant me not to hide things like that, it's fine if you didn't mean that kind of thing, most people wouldn't mean that kind of thing."

He'll gather her in to hug her.  "It is what I meant.  Thank you for not just hiding the whole thing.  I appreciate that part a lot.  And, I understand.  It's my responsibility to not be unduly influenced by you being sad.  Now that I've asked you not to hide what you'd usually hide, at least for a while."

- snuggle. "Okay. 'm not - asking you to be influenced." Both Keltham deciding to fuck her and Keltham deciding to not care about her feelings are good outcomes, here.

"This is usually where I would apply creativity, it's just, I have so little grasp of magic, and all the people I would otherwise ask might be, assuming the premise, in a conspiracy with you."

Though Ione might be less likely than some, but no; for purposes of deciding whether it's okay to risk having kids, he needs to assume that Ione is scripted - by Governance, not by some metalevel eroLARP - and can't be trusted either.

"I know what Science Maniac Verrez would do in this situation - namely, figure out how to use Prestidigitation to impose a magnet-field over his own sperm, the way that mature male contraception technology works in dath ilan.  But in real life, if you try that sort of thing... well, no, actually, I guess I could heal myself, if I hurt myself.  Unless I gave myself cancer.  But that, I'd guess, just takes a more powerful cleric spell.  And even if I literally kill myself, you could bring me back... but the problem is verifying that the sperm are actually dead and that the silly clever trick worked, when I can't ask anybody here to help me figure out how to verify whether sperm are alive... but there was a spell Detect Life on Ione's list, I'm pretty sure, and if I ask my god to give me that, I can see if it works on sperm and then it goes through my god rather than anyone here..."

"Or actually - potentially simpler solutions.  Is there a fourth-circle or lower spell I can ask my god to give me, that would let me create a small object that isn't as fragile as Prestidigitating that, and can have properties like, impermeability to fluid, adhesion to skin until dispelled."

Keltham is now attempting to invent birth control via condoms from scratch!  His first visualization is a small patch that fits over the tip of his urethra and will contain the liquid that emerges from it.

....which is neither of the good outcomes! Why is Keltham like this! "I feel like there are plenty of solutions if killing people is considered an acceptable cost and you should not do things that are at all likely to kill you!"

"I don't actually know what would be a solution if killing people is an acceptable cost, though it sounds like it's not at all a great time to ask Cheliax to burn a resurrection on that."

"I mean - to be clear, under the circumstances - I might not be able to trust your solution, but - I admit to being pretty curious about what else Golarion will trade a heap of dead bodies for."

Keltham has entered Problem-Solving Mode!  Good work for having a Problem, Carissa!

"Well, you could kill me, because pregnancies don't survive dying and being raised, and you could test that in advance on some other women who were pregnant and preferred not to be, if you didn't want to just trust it. Or you could kill me and then, instead of a resurrection, do a Planar Binding to bring me back from Hell, because devils can't get pregnant....I don't know how you could verify that but Asmodeus probably wouldn't bother with Cheliax if devils could just make more of themselves in Hell. I am not very impressed with these solutions but what happens to me if I die is much more definitely known and understood than what happens to you so if we're using death-related contraceptive methods, here."

"Remind me of what your usual contraception is like.  I think you may have told me but I forgot."

"Pregnancy also does not survive a Polymorph to any form that can't itself sustain a pregnancy, and the cheapest polymorph that's sufficient is second-circle Alter Self, so I go male and back, every night when it's potentially relevant."

"Very easy to verify you doing," though the thought is more than slightly odd, "but the trouble is, at the appropriate level of paranoia, I have only sources inside Cheliax to tell me that Alter Self works for aborting pregnancy.  If I ask my god for a spell to detect whether you're pregnant, do you know if I get one?"
