Hello Anon! We do have a Jealous!Stiles tag, but I can give you some more with a bit of angst! The first two are pretty light on the angst, but the others for sure have more. :)

Stiles was not jealous. He so wasn’t. So what if Derek apparently managed to find a nice girl that might actually not even be a psychopath this time and was using his blinding grin on her, Stiles did not care. At all. At least that’s what he was telling himself as he was angrily sipping his coffee with his eyes firmly fixed on what was happening on the opposite end of the coffee shop. Which was Derek having a date apparently. But Stiles did not care.

Stiles mentally curses Erica, because in all of her warnings about how brusque this guy could be, she forgot mention that he’s also hotter than the fucking sun. If Stiles had any lingering questions about his sexuality, they’d be completely settled by what this guy is doing to him. In fact, he might not even be gay anymore. He might be in the midst of crossing into some yet-to-be-named sexuality that’s all about a scruffy black beard and alarming green eyes and muscles and tattoos and this guy’s everything ever.
The guy’s name is Derek, his lust-addled brain supplies distantly.
Well that settles it, then. Stiles is Dereksexual.
Enjoy the jealous pining (teeheehee),
