Quick Story Idea (that I won't write, because find out below)

I'm pretty sure I wasn't the first one who thought about it, but I still have to share it. No title yet, but the reason I'm not writing this EVER is because <drum roll>

I don't write clop. This is the moment you can leave safely, anything below is your fault.

Setting: Equestria, between seasons 8 and 9, Ponyville, Twilight's Castle
Characters: Spike, Starlight, Chrysalis, bit of Twilight
Description:
Starlight Glimmer leaves Ponyville for a week to (visit family/hang out with Sunburst/solve a friendship problem/go on vacation/whatever), Queen Chrysalis founds out about this, takes her form and goes back to the castle, giving an off hoof excuse why her plans are cancelled. Twilight is like "whatevs" but Spike is suspicious. He snoops around a bit and finds out the truth when Chryssi temporarily takes off her disguise in Glimmys room to monologue about her evil plans (as she often does).
Spike's first instinct is to warn Twilight and others, but thinks about it for a second, puberty takes over and, well, he does find Starlight extremely hot, so...
He approaches Glimmy Chryssi sometime later and asks her to... do the "usual" for him. The conversation goes kinda like this:
"Hey Starlight, ready for out usual fun time? <wink wink>
"Uh, yeah, sure. What do you want to do?"
"You know. This and that <use your imagination, don't hold back>"
"<Chryssi is confused and terrified> Are you crazy?! There's no way I would do this and that!"
"B-but... we always do this and that! It was your idea to begin with!"
"I-it was? <thinking: I thought I researched her hobbies!>"
"Yeah. Starlight Glimmer I know would do this in a heartbeat. Unless..."
"Did I say there's no way? I mean't 'there's no way I would miss out on that', haha...ha..."

And then they had sex. Multiple times over several days. The cats gets out of the bag when Starlight does come back slightly earlier than planned, but Chryssi manages to evacuate just in time without anyone noticing, Twilight and Starlight don't even know she was ever there to begin with.

And then Spike asks for another round of this and that. Starlight is not amused, gives him a huge speech about respecting others, telling the truth (Chryssi was a danger to them all), fantasizing about your friends (you can, but either confess or keep it to yourself) and leaves Spike ashamed and humbled. Once the situation is under control, they decide to not tell Twilight about this and that, only about Chryssi spying. And while Princess Nerdy is freaking out about a Spy, Starlight turns back to Spike.

"So, what exactly was... this and that about?" She asks with a kinky smile, leaving commenters wondering if anything else happened after that, maybe this and that became something they did on their own, maybe not, and a bunch of people asking for a sequel, with the author responding with a sly "maybe I will".

Sorry, this got a little meta in the end.

Okay, idea out, I can move along with my life.
