#lukethabaster

monster/demon hunter priest Ethan au where in addition to teaming up with demon!Luke for his work, he also has to work with vampire!Al. Alabaster is a fairly recently turned vampire, maybe only a couple of years, and he hasn't quite gotten used to everything. Drinking fresh blood gives him such a rush as if he's intoxicated, partially because he's still at the point where he gets so fuzzy and desperate when he needs to drink. Ethan doesn't quite like working with monsters but Luke is useful and Al is just pitiful. He tries to help Al get used to working off of less blood for longer periods and getting his supply from safe and responsible sources, but sometimes when all else fails Ethan is the only available source and they have no choice but to resort to Al drinking straight from the tap.

By the time they cave, Alabaster is delirious with thirst and practically begging on his knees. His mouth starts watering when Ethan carefully unbuttons his cuffs and rolls his crisp white sleeves up to his elbows and hold his wrist out for Al. Or, later on when there's more trust and intimacy between them, Al can watch and nearly combust while Ethan removes his pretty white clerical collar and unclasps the uppermost buttons of his cassock to bare his neck for Al. And Al throws himself at Ethan, sinking his teeth into his skin and doing to town while Ethan idly pets his head. Depending on how they're standing, Al would love to have Ethan's leg resting between his to give him something to grind or hump against while he feasts (and if Al is drinking from Ethan's wrist it puts him in the perfect position to be on his knees humpung Ethan's shoe). They'd probably have Luke watching things just in case, if Al gets overzealous or caught up in his thirst and starts to overindulge, Luke can grab him by the back of his neck or by his hair and yank him off. Al would be reaching out to Ethan, desperate to get more blood in his mouth until his head clears and he sees how pale and weak his little priest is (and maybe Ethan only let it go on for so long because part of him gets a little horny for how desperately Al wants him).

Alabaster and Luke would probably be mildly jealous of each other and always competing in subtle ways, and probably fucking each other as a proxy for fucking their mutual celibate priest. The day Ethan casually drops that he's only an honorary priest and hasn't technically taken any vows of chastity, those two become the most insufferable bitches ever.

Alabaster going from feeling so high and mighty because he's a noble courtier with a high position in court while Ethan is just some lowly brute with a sword, to Alabaster being on his knees for that brute. Ethan takes their prince, the most noble blue-blooded person in the entire kingdom, the very prince Al intended to bend to his will, and Ethan makes Al watch and he fucks him over the arm of his throne, crown askew, while he begs and moans for Ethan to go harder and faster. Al is humiliated on Luke's behalf and is even more humiliated by how badly he wishes he was in Luke's position. But Alabaster is a loyal servant of the crown, and he obeys when Ethan tells him to clean up the mess their prince made of his throne and his legs (with his tongue ofc).

I like that OT3 a lot. I've never really been in Lukethan but Lukabaster and Ethabaster are two ships I appreciate a lot. And I think it works really greatly as a OT3.
