Ask if it the pump could also be used to extract breastmilk

As you looked at the pump thoughtfully, another nagging thought occurred to you: you've never seen anything like this before, but if you had to imagine how it would be used, wouldn't it be more natural to think the thing was put over a woman's nipple and used as a breast-pump? It seemed like the rubber end would attach very easily there and pull milk into the chamber. It could, in theory, be used to help woman who needed to feed a baby and lacked the ability to get the milk out, for reasons biological or psychological.

Liens inspected the device for a moment, then nodded. "Yes, in theory. Sure. It could work for that. In fact. Probably based on that model. That sort of thing exists. For nobility. In the capital. Some mothers use them. Expensive," she explained, shrugging and frowning at the little metal box. "So yes. Based on breast pump. But we're going to use it as a dick pump. It was modified by the inventor. Works for that purpose. Don't know why they wanted to make it that way. Don't need to know. Looks like it'll work. Well."

Clearly, she wanted to change the topic back to her intended use of the device: pumping your dick and extracting your semen for her experiments.

But...

You couldn't help but look back and forth between her rather sizable bosom and the pump.

Her eyebrows lowered critically and her frown became a scowl. "What? Me? You want to pump my breasts? Is that what's going on here?"

Was that even possible? You had to ask the question out loud to get an answer; she wasn't going to be forthcoming.

The woman crossed her arms and knit her brow, looking as though she suddenly had a headache. "Yes. On a lactating woman. A mother. She would produce milk. You'd put the cup over the breast and suck the milk out. Then it goes into container. Transferred to bottle. Storage. Complete." She placed one hand on her hip and leaned over towards you. "I am not a mother. Obviously. Idiot."

There was a silence between you. She sighed the deepest sigh you'd ever heard in your life.

"I do. Lactate."

Your ears perked up.

"I don't know why. Biological. Look it's. Not important. Or useful. For anything. I'm not a mother. I will never be a mother. Not important."

...

Your eyes fixed back on the pump. The thought wouldn't leave your head. Here, you had a saintess uniquely capable of producing milk without pregnancy-- or at least, you assumed the others didn't ordinarily make any. A weird, unique opportunity had presented itself for an especially perverse squire. {if Master = True}You weren't sure if you'd call yourself "perverse," but you did seek to establish a position of authority as a squire. You needed to show Liens that she ought not have any hesitation doing this sort of thing for her husband. Maybe this was the perfect way to do that?{elseif Servant = True}It was probably too much to ask Liens to do, right? You should probably just forget about it. You're supposed to let her milk you, not the other way around...{elseif Chivalrous = True}This sort of thing has no place at all in the knightly code of chivalry. For the sake of appearances, if nothing else, you figured you should probably forget about it.{elseif Freak = True}And here you were: the most perverse squire of them all. Of course you want to watch Lien pump out breastmilk and drink it too, if possible.{elseif Lady's Man = True}It wasn't like you wanted a tall glass of elf milk or anything, but you did really want to see her boobs. This would be around-about way of doing that, if you could convince her.{else}Of course, your mind was on duty above all else. There wasn't really any place for you to consider something so rash or something so likely to be demeaning to your saintess. And yet... the thought remained.{endif}
