FlashWeather + Lightning?
So honestly, this ship really isn’t my cup of tea but I’m gonna try my best for you Nonnie.
The first time a natural lightning storm happens after they’ve been hooking up for a while, well, it’s quite an eye opener for Mark. He knew Barry was sensitive but damn!
So its an enjoyable night for them, Barry especially when he literally came so hard he passed out. And Mark? Mark’s always enjoyed an enthusiastic and responsive partner like Barry is.
It doesn’t hit Mark until a few days later, that hey! Barry was super extra the night of the storm, I’ll just whip one up and get him going….only..it doesn’t work for some reason? So Mark pulls in Hartley, cause he’s a kinky little shit but he’s a smart kinky little shit who’ll help Mark conduct an experiment.
Only the results? They aren’t what Mark was hoping they’d be. Turns out Mark’s lightning doesn’t affect Barry the way natural lightning does.
And yeah, Mark’s totally bummed out but it does mean from then on out, he definitely clears their schedules when natural lightning storms hit Central.
(And sometimes if he can talk Barry into it, surrounding areas as well.)
Send me a ship/character + a word, and I’ll give you a head canon.
