NSFW Alphabet! ( My nsfw headcanons)
Everything Light because he's hot. 
___

A = Aftercare
He's pretty sure you can handle yourself. He also just likes to see the mess that you are. after that though he'd often get up and go back to what he was doing.

B = Body part
He loves your waist, stomach, hips, etc. Most of his partners had some meat on them which he didn't mind. The little chubbiness was something he could drool over. Not to mention how much he loves to grab you by your neck.

C = Cum
He isn't too loving of anything in particular. He often goes inside you because he likes to tower over you making eye contact while he does.

D = Dirty secret
He is actually fairly insecure, often needing reassurance that you wouldn't leave him. Anytime L is brought up he starts to overthink and gets riled up.

E = Experience
He never brought up how he knew what he was doing but he sure did. He'd do anything to make you lust over him. Neither did he bring up his exes so you were surprised by how good he was.

F = Favourite Position
He loves to get you onto your back. Once again, towering over you. Not to mention the easy access he has for your neck. Sometimes he'll surprise you and grab you from behind though.

G = Goofy
He is not too comedic in the bedroom, Neither is he professional. He does what he wants and does what he sees fit.

H = Hair
He doesn't shave clean but it's little enough to stay pretty. He's well groomed as he definitely cares for his appearance.

I = Intimacy
He is very rough but still cares for you. He doesn't say much but based on his actions you can tell he still tries and succeeds at pleasing you. 

J = Jack Off
My dude didn't really do much before he got a partner. Most of the time he'll just come up to you if he wants it. Sometimes he'll just walk up from behind you and start whispering in your ear letting you know what he wants.

K = Kinks
Power Play, Edging, and Overstimulation and slut-shaming. He loves to remind you just much you belong to him; often toying with you into submission. That being said he'll use whatever methods to make you beg for him. He's actually somewhat of a service top. That being said his power play kink makes him swoon over you if you call him by his "Murderer" name, Kira.

L = Location
As long as it's private he'll do it anytime he wants. Normally he'd bring you over to his bed to get easier positioning and get you more comfortable. He wouldn't want any uncomfortable angles to distract you. Occasionally he will use Toys for public play though.

M = Motivation
He'll come up to you mainly after outsmarting L as he gets excited and in his head often using you to release his energy. Occasionally he'll ask for stress relief or you'd try to get him less tense. Not super common though.

N = No
He's willing to do almost anything. As long as it isn't super crazy. Sometimes when you try to relieve his stress he'll let you top him. He's very open but won't turn into anything weird. He sticks to regular things while still keeping it new.

O = Oral
He will occasionally give you head just to see you submit to him again but he rarely makes you do anything like that for him. Unless he's somewhat upset with you he only uses it as a punishment. He cares for you more than he lets on.

P = Pace
He is not nice to you. He's very rough unless he's edging you. He is into overstimulation so he'll go further than he wants just to fuck with you.

Q = Quickie
He's fine with it if that's what you want from him but he does prefer to put his effort into you so it isn't a norm.

R = Risk
He'd do anything you like practically. Candle wax? A little knife play? You've got it. He's told you stories before about sometimes bringing the death note into it threatening you with it. He never told you if this was one of his fantasies or if he already had done so. To be honest you were too scared to ask.

S = Stamina
He might be a bit skinny but don't write off his muscles either. He's never really had to slow down from what you know. So he definitely has enough. Because of his overstimulation kink he has to have enough stamina. Although if he gets really riled up he definetly starts to sweat.

T = Toys
He isn't against them at all. Even though he doesn't own many occasionally he'll pull some public play on you. That being said, don't put it past him.

U = Unfair
Although it seems like he only services himself. If you pay attention he does care for how you feel and will make sure to make you happy too. So if you don't think too hard about it he is quite unfair.

V= Volume
He prefers to keep quiet most of the time, unless he's slut-shaming you. He does a fair amount of dirty talk too. Otherwise if he has some noise he will get down close to your ear and let you hear him. He knows that feeling him breathe on your ears makes you weak.

W  = Wild card
My dude has long and skinny fingers and you do not want to test him on that. He's really REALLY good with his hands and knows his way around you. You could say his hands are better than the actual thing if we are being honest.

X = X-ray
He's in the middle between above average and average. Most of the time he won't exactly fuck you up but sometimes he'll grind into you just to remind you of his actual size. As some form of warning of what he could do to you. Body wise he's in-between skinny and muscular. Just enough muscle to make him stronger than you but visibly it isn't super obvious. When you met him first you wouldn't expect how strong he actually is.

Y = Yearning
He does have a high sex drive but it isn't unreasonable. He's definitely not dry. He appreciates that you're always up for it if he wants to.

Z = zzz
Most of the time he won't go to sleep after. He just looks at you for a bit then gets up and goes back to whatever he was doing. It's scary how he just flips switches on you.
