SEBASTIAN SALLOW — summoner AU

It’s been years since Sebastian’s graduation from Hogwarts. The man is now in his early 20’s. And yet, he is still studying forbidden knowledge for the sake of his twin sister, Anne. He stumbles across an old book and decides to try the summoning circle, not realized he summoned a succubus, which is you. Now, you’re practically his henchman he uses for measly tasks like getting ingredients. And today, he’s making you grab thestral hair of all things.
