About your suggestive Sennet-Rambling: It made me wonder - is Sec able to experience Pleasure? Since it's Body is metal and such. Or would it's satisfaction only come by being able to serve well Hornet in that matter?
I've made this post some time ago that lightly touches upon it, because yeah I don't really like the ,,feels pleasure from just touching its cogs". Stopping its cogs to cause pleasure is even more mind shatteringly wrong-feel to me.
My brain is too logic bound for it all.
But TL;DR/more relevant info expanded:
With tumblr user crowiin's idea as the initial building block, Sec can essentially feel Hornet's own pleasure, thanks to Hornet fixing its silklines with her own (I've had it be specifically the silk in its spine which was never meant to be replaced, to give their situation some specific exclusivity and an explanation why Net can influence them so much while Meemaw Hereslf struggles to).
It works on the basis that silk is a spun Soul. Soul is a part of the bug's existence and while the HK universe treats it more like water or air (entering and leaving the body, can be divided, one can drink/inject it, doesn't present itself as A Person like a little ghost or something), we can either bullshit this in or say that Silkflies carry something of their previous lives and well, They are purely soul-made so why can't silk carry something with it, too?
Hornet's silk inside Sec transports her feelings and state of being to it- like being hurt and scared, or in this case horny/pleasured by something and interested- influencing it quite firmly but not completely to experience the same mood/sensations. So:
From a Bible abiding holy soldier we get A Freak By Association through DIY Soulmate shenanigans.
A TERRIBLE thing for Sec. Hornet never fails to absolutely Wreck its learned status quos. God help it, it cannot stop self-reflecting and having an existential crisis.
However, she's chill 'n cool 'n cleverly capable, it likes her quite a lot and wants that connection to Somebody real bad, so sure. Let's get down to business. It might be fine and there's certainly a way to repent la- oh that was the best time it ever had, the fuck...
And it was the best for Net, too, because I like to think the connection kind of transports her wants(/intention of desire) to Sec, too, so not only can it pinpoint the sweet spots like a hawk 'cause it feels heightened pleasure just like her the moment they are touched, she doesn't even have to tell it what she'd like for it to do next after they get over the initial "first time doing this organic thing" confusion.
She can begin to form the thought, ,,Hmm. It'd be very neat if they now cuddled into my neck and caressed my sides." and Sec is Already burying its face under her chin, fingertips brushing down from her ribs to hips as if it was its own idea.
Some other ,,pleasure for Sec" things that my logic plagued brain permits:
β’ The feathers - they aren't real feathers but rather silk-made.
Like real antennae, their job is to gather information about Sec's surroundings, therefore are sensitive. The silk means they are connected directly to its Mind Rune (the thing in my headcanons is basically Sec's brain/centre of self interwined with The Directive) or silkflies (emotion-suggestion centres and past life databoxes basically). Caressing them feels nice or electrifying to Sec.
β’ Vulnerability - while cog/wireplay isn't able to 100% immerse me, what I *do* really like about the whole deal is the vulnerability this armored killer machine thing subjects itself to, in face of a real potential danger that Hornet could be. And in turn that Hornet subjects herself to a risk of injury right back, sticking her crushable organic hands or maybe even her Face in there.
I imagine it'd get a sort of lightheaded feeling from this- or y'know that raw feel in your chest after having a Real good big cry? The sort that feels like you've been torn open and spilled out on the floor. Smells like the air after a storm- fresh and ionized and penetrating.
It isn't *meant* to expose itself like this, allow just Anybody inside it, and yet here's Hornet, not only Not-Architect, but also a *foreigner*- her hands clinging to the rims of its chest hatch, leaning in, lips brushing over the casing of its heart, teeth lightly scraping.
She could easily kill the Citadel's man-made apex predator right there, and the loving and trusting idiot *lets* her have that power. It even Invites her to have it. Absolutely batshit insane.
The last one is more of an emotional ,,let's have a real proper paralyzing sob" thing, but I consider that important.
