A = Aftercare (What they’re like after sex)
Mettaton tends to go overboard with aftercare no matter what. So make sure they don't go overboard, they mean well though.
He will run a nice bubble bath that's infused with healing magic. Afterwards they would give them a drink and a snack. C u d d l e s all the way. Holding their lover close to their body.
B = Body part (Their favourite body part of theirs and also their partner’s)
They could go on and on about their lover’s body and personality. But he would have to say it would be their mouth, the way they smile and the way their lips feel against theirs.
He can't stick to one favorite part of the body at all. Since after all they have never had a physical body before.
C = Cum (Anything to do with cum basically… I’m a disgusting person)
Its a hot pink in color and is transparent. It also seams to have glitter in it as well, shouldn't be surprised at this fact. It doesn't really have a taste to it. The feel of it is smooth yet sticky. The glitter is hard to get off, so his lover will have glitter where ever their glittery cum has gotten. (or in fact it just ends up all over)
D = Dirty Secret (Pretty self explanatory, a dirty secret of theirs)
Only Alphys knows this since she made their body, but Mettaton has both sexes.
E = Experience (How experienced are they? Do they know what they’re doing?)
They don't have much experience since the whole physical body thing is still new to them.
F = Favourite Position (This goes without saying. Will probably include a visual)
They love the cowgirl position and a few others similar to it.
He also is into the waterfall position where they can hold onto their livers hips or waist.
G = Goofy (Are they more serious in the moment, or are they humorous, etc.)
They're a drama queen so he would be very dramatically serious. Though that doesn't last long and he giggles. They would be overly dramatic for giggles.
H = Hair (How well groomed are they, does the carpet match the drapes, etc.)
He is squeaky clean! He makes sure he is always clean from day to day. If they get a little bit dirty they will give himself a scrub down.
I = Intimacy (How are they during the moment, romantic aspect…)
He would be dramatic on purpose, l o a d s of praises.
J = Jack Off (Masturbation headcanon)
When he first got his body they tried it out, bit too messy so he won't do it very much. Besides they have a lover now.
K = Kink (One or more of their kinks)
His kinks are,
Pet play, sensation play, and shibari.
L = Location (Favourite places to do the do)
Anywhere that’s safe from being spotted by any of his fans. Though usually in his room.
M = Motivation (What turns them on, gets them going)
His lover flirting with him.
His lover wearing something in his colors.
Them wearing lingerie.
N = NO (Something they wouldn’t do, turn offs)
Seriously hurting his lover is a big no for him.
Any other fluid besides cum is a no.
Flirting with someone else gets him super jealous and he won't feel the need to be intimate with them for a while.
O = Oral (Preference in giving or receiving, skill, etc.)
O H Y E S ! !
He loves giving to his lover especially with that trick he can do with his tongue.
He is interested enough in getting too, just be careful of all the glitter.
P = Pace (Are they fast and rough? Slow and sensual? etc.)
His pace is quick and sensual.
He can't help himself but to go quick but he does enjoy his time so he is gentle and loving.
Q = Quickie (Their opinions on quickies rather than proper sex, how often, etc.)
E V E R Y T I M E before he goes on stage.
R = Risk (Are they game to experiment, do they take risks, etc.)
Alphys has caught them both and gotten a nose bleed from it plenty of times. Same goes with Undyne since she comes over for anime nights.
S = Stamina (How many rounds can they go for, how long do they last…)
Maybe 4 to 6 rounds at most. He does need to recharge his body though so depends how charged up they are.
T = Toy (Do they own toys? Do they use them? On a partner or themselves?)
He has both sexes, and a vibrating tongue. So won’t need much use for toys, but he does have a few that go good with those kinks.
U = Unfair (how much they like to tease)
He would tease his lover with his fingers and their tongue. He can't do a teasing pace because he gets lost in the pleasure.
V = Volume (How loud they are, what sounds they make)
They are pretty loud.
Yelling out praises and saying how great his lover feels, giving lots of praises.
W = Wild Card (Get a random headcanon for the character of your choice)
He was very nervous for their first time. But after a few times of being intimate he is a cocky drama queen.
X = X-Ray (Let’s see what’s going on in those pants, picture or words)
His dick is a hot pink with two black stripes making a circle one under the head and one on the middle of their shaft. Also looks like there’s glitter in the pink parts.
His length is up to being 6'4 inches at most and his girth is on the slim side but has some thickness to it. The head is thick yet has a softer feeling to it, glitter seams to take up most of it.
Y = Yearning (How high is their sex drive?)
Very high but he will wait until they get the both of them to somewhere hidden enough to take his lover, or have his lover take them.
Z = ZZZ (… how quickly they fall asleep afterwards)
If they have sex in his room then he would wait until after he is done aftercare to recharge themselves.
