Yep, Ninety is a little gun/PDW! Generally, body size correlates to gun size (with some exceptions, like Arisaka and Benetta...).

. . .

Ninety

He takes it well enough— people bathe dogs, after all! You're just awfully nice for doting on him so much. In no time, Ninety gets all shivery from your touch, trembling so badly that you'll practically have to hold him in your lap to keep him upright. All the warmth and contact feel so good that it's hard to make his body cooperate. Even if he's a bit nervous, he's still so, so very grateful for the spoiling.

Kirsch

He has no idea how to process affection outside of a sexual context, so that's exactly what he does. Tries to make it sexual. That has to be the reason why you're pretending to dote on him, right? When nothing sexual happens, Kirsch suddenly has a lot worse time processing this. He's fidgeting in place, visibly nervous and flustered with having to just sit there and let you spoil him. It's not fair.

Mauser

He fully assumes that this is going to be just another way of serving you. Even if you let him help you first, being bathed feels terribly doting. Mauser is even more uncomfortable because of how much he likes it. Being held and cared for by his Master feels so right that it's hard to properly protest. Despite his reluctance, it's impossible not to give in and relax when you're handling him so thoroughly.

Karl

Bathing together is a bit... intimate, isn't it? If not that, then is this another attempt to treat him like a child? Karl is hesitant to do anything that might make him look pathetic or undignified in front of you, but if you insist, he has no choice but to endure. The worst part is that he doesn't actually hate it. Being touched and cared for feels nice, so long as you're not too patronizing about it.

Cutlery

He's so very flustered. As much as Cutlery likes the idea of being spoiled, he's way too embarrassed to accept it without a fight. When you finally talk him into it, he tries to huddle up in the corner of the shower and avoid as much contact as possible, afraid that he's going to do something stupid if he lets himself enjoy it. That, of course, doesn't stop him from melting once you actually touch him.
