I draw, I write, I gay

A = Aftercare (what they’re like after sex)

Depends… it always depends on his mood… if he's in a better mood he may be more likely to carry you to one of the baths, though if he's not you're left to fend for yourself

B = Body part (their favorite body part of theirs and also their partner’s)

He likes EVERYTHING about himself quite a bit–why wouldn't he? He's perfect. (At least in his eyes (and our eyes))

His favorite body part for you would be your hands and legs. Your hands because of how much smaller they are then his and your legs because of how they wrap around him when he fucks you  

C = Cum (anything to do with cum, basically)

He likely cums plenty, mainly because hes probably bigger than you, he would also like to cum both on and in you in a claiming way, anyway to make it clear you are his

D = Dirty secret (pretty self explanatory, a dirty secret of theirs)

Liked (and would still like) being dommed by Fabien and only by him

E = Experience (how experienced are they? do they know what they’re doing?)

DEFINITELY knows what he's doing, mainly cuz he’s done it a lot, but the end of it you will be left (to quote Aaron) sore and begging for more  

F = Favorite position (this goes without saying)

Prefers being above you, able to control the pace, pin you down, watch you squirm.

G = Goofy (are they more serious in the moment? are they humorous? etc.)

May be a little goofy beforehand mayhapes make the occasional joke but other than that its pretty limited 

H = Hair (how well groomed are they? does the carpet match the drapes? etc.)

Carpet of course matches the drapes with a small snail trail and comfortable amount of hair without it being annoying 

I = Intimacy (how are they during the moment? the romantic aspect)

It can differ, some days he’ll call you sweet names if you call him ‘master’, if you don't it will likely be FAR less intimate

J = Jack off (masturbation headcanon)

As noted by Gabrial, Nikita is very much a wanker at least if there is somehow no one to fuck around

K = Kink (one or more of their kinks)

Being in control(likes being called master)

Being able to pin you down, you will not be able to switch positions unless he does

You worshipping him, he would love you to tell him how amazing he is and for you to want to please every inch of him 

L = Location (favorite places to do the do)

Everywhere. Does not care if you could get caught or even if you do, that's part of the fun

M = Motivation (what turns them on, gets them going)

You existing. As stated before he. Loves. Fucking. Doesn't take a lot to get this man in bed

N = No (something they wouldn’t do, turn offs)

Bottom. Unless he loves you and trusts you like a whole fucking lot you arent topping in anyway shape or form.

O = Oral (preference in giving or receiving, skill, etc.)

Loves to see you one your knees giving him head, though that is not to say he isn't skilled HE IS, HE VERY MUCH IS, you just often won't be able to appreciate that (maybe if you beg well enough)

P = Pace (are they fast and rough? slow and sensual? etc.)

it is often rough and fast, though it truly could be either depending on his mood. If he's feeling nicer, probably slower. Either way you will likely never be in control of the pace.

Q = Quickie (their opinions on quickies, how often, etc.)

You will likely do plenty but he would prefer taking his time, if you end up doing a quickie then its likely you on your knees giving head

R = Risk (are they game to experiment? do they take risks? etc.)

He's 648 years old, he's likely tried every he would ever want to and probably liked everything that but him in control, so if you want to do something like that he would NOT be apposed 

S = Stamina (how many rounds can they go for? how long do they last?)

Stamina for daayyyyyyssss, could easily keep going till the sun has risen and set back down again

T = Toys (do they own toys? do they use them? on a partner or themselves?)

Not likely to use on himself or you, though if you have them for yourself I doubt he’ll care

U = Unfair (how much they like to tease)

Delights at the sight of you begging, will do anything that brings you to your knees or pleading through tears  

V = Volume (how loud they are, what sounds they make, etc.)

Mostly grunts or  the random joke, most of the noise would likely come from you or the likely to be murdered victims. He may also sigh occasionally either from bored or pleasure 

W = Wild card (a random headcanon for the character)

Would use the Whip on you to command you to do something rather than tie you up, etc {credit for this idea goes to @nobetterthanisla}

X = X-ray (let’s see what’s going on under those clothes)

Will very much need to stretch beforehand, cuz he's BIG, you feel him everywhere and are still sore days after

His ass on the other hand is thick AF (babes never skips leg day)

Y = Yearning (how high is their sex drive?)

So about that… he is willing to fuck just about anyone anywhere anytime. During breakfast - why not? After a battle - YES. At the most inconvenient of times – yes that's the best time to do it

Z = Zzz (how quickly they fall asleep afterwards)
