I was wondering if i could give you a story suggestion!
The ship is Klance (obvi) Lance is top, Keith is bottom. Shiro and Allura want to try a challenge with a serum that can turn someone evil for a specific amount of time (depending on how much you give them). Lance volunteers to take the serum and everyone votes Keith to be the one that fights him. Shiro and the rest of the paladins go to a safe place to watch the battle. Turns out Lance is a lot stronger than they thought and Keith hinds behind a rock to try and make a game plan , so now the rest of the paladins and Allura have to try and help Keith distract lance long enough for Allura to slip in and inject lance with a serum that makes him go back to normal. Pidge keeps feeding Keith bad ideas and Keith thinks those aren't going to work. Shiro says to Keith that "Even though your in a tough situation Lance is still Lance!" That rings a bell inside of Keith and then he thinks, 'That's right! Lance is still Lance, that means all i have to do is remember one of his weaknesses and i can beat him! But what's one of his weaknesses?' Keith goes silent for a bit. 'Lance is flirty so all i have to do is be sexy around him' Keith blushes at the though. "here goes nothing" Keith approaches Lance and starts awkwardly flirting with him. Lance gets super confused and starts to get annoyed. Allura finally slips in but then accidentally slips over herself, Lance turns around to see what the noise was but then Keith panics and turns Lance around and starts making out with him. Lance thought this was extremely hot and leans into the kiss making it even more heated. Then hands start going under shirts people start moaning, y'know all that good stuff and then finally Allura injects Lance but Lance and Keith are still making out so allura kinda just leaves and that's where the smut comes in. (Btw Evil Lance is SUPER hot) sorry it was long
