#a purchase just means Fingon is his Current master

[fuckingfinwions]

Dark!Fingon buys slave Maedhros from Morgoth.

Canonish timeline through the flight of the Noldor and Maedhros’s capture. But when the Nolofinwean host arrives, Fingon doesn’t charge off north unprepared (or maybe he tries, but doesn’t find Maedhros and so turns back). He works with his father to build a fortress and train an army. 

Eventually, the Noldor under Fingolfin can negotiate with Morgoth from a position of strength. Fingolfin is willingly cedes the Silmarils as part of a mutual non -aggression pact. He doesn’t like agreeing not to attack his father’s murderer, but he doesn’t expect Morgoth to actually be left in peace - the Feanorians won’t let him while he holds the Silmarils. There’s symbolic wereguild exchanged for the dead elves and orcs that ‘happens’ to work out exactly even. So Morgoth rules the north and the Noldor and Sindar rule the rest of Beleriand, with elves and orcs mostly giving each other a wide berth. There’s a pair of embassies or similar at the border, so that diplomatic requests can be heard without either king going into the other’s territory.

Fingon walks in the Angband embassy and says he wants one of the prisoners. (There are also a lot of Sindarin prisoners, as Morgoth says they’ll be released if Thingol negotiates for them, and Thingol will not some so close to Angband, but there wasn’t much chance for Noldor to be taken prisoner.) He offers a cloak from Valinor blessed by Manwe in exchange. Morgoth likes powerful magic, especially if it’s stolen from the other Valar, even when it burns him, so he accepts.

Maedhros was in Angband for decades longer in this timeline than the canon timeline though. Morgoth has always been his overall master, but he has been transferred from one general to another as  reward before, and on the trip to the embassy doesn’t initially notice it as different.

Fingon is determined to keep it that way. That is, Maedhros is no longer in Angband, but he belongs to Fingon as surely as he did to anyone.

Maedhros is brought in naked to the embassy, and immediately kneels on the ground without looking around.

“Maedhros, I’m so happy to see you! It’s been so long, but everything will be alright now that I have you.”

“Fingon? What are you doing here, Angband is horrible! You should get out while you can.”

“Don’t worry, you’re not in Angband anymore, and you won’t ever have to go back again.” Fingon reaches out a hand to tilt Maedhros’s head up and force him to meet his eyes. (eye contact promotes trust and shows sincerity! physically manipulating Maedhros’s body reinforces that he doesn’t get to make choices! win/win for Fingon!) “I bought you from Morgoth. You’re mine now, not his, and I have no intention of sharing you.”

“Oh. What do you desire of me, Master?” Maedhros is confused, but that’s not new, and this phrase rarely makes things worse.

Fingon kisses him. “I desire you, in every manner possible, for the rest of your life. I already a few things ready for you in my rooms in Hithlum. Not clothes yet; I wasn’t sure your size, but jewelry and more pillows for the bed and such.”

Maedhros nods. “Thank you.” Maedhros has learned not to hope, but he’s either going to be allowed multiple hours a week lying in a bed or Fingon has a pillow fetish.

“There’s no need to thank me when you haven’t actually seen it yet! Come on, let’s go.”

They go out to Fingon’s horse and ride back south. Fingon brought a spare cloak, so Maedhros is more dressed than he has been in years.

It’s a long journey, several days. At night, Fingon fingers Maedhros open, then fucks him hard and fast. He asks Maedhros to blow him in the mornings to save time, and sometimes when they stop for lunch.

Over the next several months Maedhros realizes how kind of a master Fingon is. Fingon usually wants sex to feel good for Maedhros as well as him. He doesn’t whip Maedhros just for the hell of it. He gives clear orders like “get on your knees so I can fuck your throat” rather than making Maedhros guess. He generally likes when Maedhros is loud, and if he doesn’t will gag Maedhros rather than punishing noises. Most amazing of all, Maedhros sleeps in the bed beside Fingon every night. Maedhros is incredibly comfortable, and has no need to worry about not waking up in time to serve his master - Fingon’s right there, and Fingon doesn’t even have to wait for him to wake up to start fucking him.

The most painful part is removing Morgoth’s brands. Even with a sharp knife, slicing off skin hurts.  But Fingon is kind for this as well. He ties Maedhros up before the surgery, in case Maedhros has trouble holding still. The biggest marks, like the one on his inner thigh as big as his hand, Fingon even has Maedhros drugged for the removal. Fingon explains that the pain killer is difficult to make and also he’d rather Maedhros not become addicted, but just this once it’s worth it. The cuts are always bandaged after, and Fingon lets Maedhros ride him while they’re still raw, rather than Fingon holding him down and causing pain from a carelessly placed hand.

The only mark Fingon makes on Maedhros is small, just a couple inches long, and done with a needle rather than a branding iron or a sharp knife with salt rubbed into the wound so it will scar. “Property of Fingon” tattooed behind Maedhros’s balls isn’t surprising, and is reassuring that Fingon really will keep him.
