Character: Mettaton
Prompt: Masturbation

Boiling Over

[(Anonymous)]

(Here you go OP, it's not long but hey, someone has to write a fill for this meme eventually!)
Click
Mettaton’s fingers parted from the metal lock of his door, teeth pressed over his bottom lip. In an attempt to make his heels clicking against the floor as quiet as possible, he scurried across the room and dove into his lavishly covered bedspread. Though he took great pleasure in showing off, this could be considered more of a rehearsal than a performance.
His legs in this body were still shaky- quite literally. He’d experienced a physical form inside the box that Alphys had temporarily attached him to, but making the switch between rolling and walking was tougher than he’d imagined. But he had very little to complain about. This body was beautiful as he ever could have wished for; and he had every intention of loving it.
Shifting his weight onto the plush sheets, Mettaton spread his legs apart. His body hadn’t been equipped with any form of human genitalia (yet, he told himself. More convincing and he’d be able to work out some kind of deal with the woman.). However, that didn’t mean that his corporeal body didn’t come without any form of erogenous zone.
His fingers made a beeline for the core of his stomach, slipping over the heart-shaped indentation. The magenta surface was smooth to the touch, moving with his breath and having some give under his touch. He pressed two of his fingers together, toes curling as he rubbed the surface. A shiver ran up his spine, a lewd grin pressing the corners of his lips. The android continued to rub, making indentations in the putty-like substance until it began to sweat. The surface became hot, beading up as it started to melt like warm wax.
Mettaton pressed his fingers into his softening center, flicking them back and forth inside. He gasped, fans whirring behind the metal plate in his chest. He squirmed as he fingered his own core, waves of pleasure bursting with every twitch of his hand. By now the putty had started forming a thin goo, sticking to his hand and running off onto the mattress. At least the color matched the sheets.
Toes curling from ecstasy, Mettaton covered his mouth with his free hand. His hips bucked up into his own fingers, sending them deeper into his belly. The heart began to swell beneath his hand- a sure sign that release would soon be coming. Mettaton had to grit his teeth to keep from groaning out into the open air. That was a symphony best saved for later.
The heart continued to swell and bubble with goo, completely overflowing from his stomach. Electric waves of pleasure shot straight from the sticky surface to Mettaton’s head, lighting up every nerve in his metallic body with bliss. His eyes rolled back, mouth wide open in a silent scream as the heart finally burst. Like a pot boiling over, the fluid substance bubbled up and burst from the pleasure of his fingers. Mettaton arched into the mattress, causing it to creak from the pressure. A squeak escaped the back of his throat, and he laxed, coming down from his pleasured high.
After collecting himself, the android sat up. He pulled at the sticky goo that had burst from his core with a mild sense of disgust. It would be a hell of a lot less messy if he could just have a cock instead.

mettaton/napstablook, kissing

[(Anonymous)]

I want the ghosts to smooch.

Mettaton teaches Napstablook how to kiss and things gets spicy. Napstablook can be a robot or a ghost. Either is fine to me.

Re: mettaton/napstablook, kissing

[(Anonymous)]

There was something about the MTT franchise that made people go wild. It probably helped that Mettaton had a super solid viewer base among the monsters, but the humans had similar tastes when it came to entertainment. Live shows with Blooky and Shyren sold out in hours – well, the last one was fully booked in fifty-nine minutes. It was insane. It was glorious. Mettaton couldn't get enough of it.

Blooky, as always, put their everything into making the shows sound amazing. Between the tours and the mixes and all the fans (who would indeed smooch a ghost, oh yes), they'd been wearing at the edges. Alphys noticed in time, though, and offered to create a robot body for them. In cyan. And promptly refused to accept half of MTT Entertainment in thanks.

“One last thing, Alphys, dear,” Mettaton had hissed then, in his best stage whisper. “They need to be as adorable as they are right now.”

Alphys had stared at him, thinking, and then she'd given him a conspiratorial grin.

Napstablook hadn't taken the news well. They'd stayed hidden till Alphys had sent them a list of the robot's specs. Blooky had been positively teary at the thought of so much processing power. Mettaton had sent them off with a hug.

They came back looking absolutely precious.

Nobody could see them like this. Not yet. He'd plan a big unveiling, eventually, but not right now. Mettaton wanted Blooky to himself for a little while.

...

“having arms is strange,” said Blooky, wiggling. The two were in their hotel apartment, practicing moving around and holding stuff. They picked things up really quickly. “do i look okay?” they asked, and it wasn't the first time.

“You look amazing, Blooky.” Mettaton could just eat them up, the darling thing. Alphys had somehow managed to keep their large liquid eyes. The fans would go berserk.

“oh, gee...” Blooky sighed, their lower lip trembling, and Mettaton was suddenly reminded exactly how much detail had been put into Napstablook's robot form. He pressed a hand to Blooky's cheek, and watched the synthetic skin under his fingers, softer than his, it was some human invention that Alphys had been very keen about, and now he could see why. “metta?”

“Yes, Blooky, dear?”

Blooky seemed to be bracing themself. “you… you know how you… oh, never mind...” They hung their head.

Mettaton giggled and chucked their chin. “I do a lot of things, Blooky. And you simply must tell me what I did this time.”

Blooky attemped a watery smile. It didn't quite work. They sighed again. “i know it's for the show, but… sometimes… you kiss people.” They looked up into Mettaton's eyes. “i was just thinking… what does that feel like? how do you…?” Their eyes widened a bit. “i was only asking. you don't have to answer… or anything...” Their head dropped again.

Mettaton blinked once. “You want me to teach you how to kiss?”

Blooky was panicking now. “You really don't have to,” they said, spots of blue high on their cheeks. “i mean, it's not as if i'll--”

“Oh, silly, of course I'll teach you!” Mettaton was delighted. He would have phased right through Blooky's ghost form, but this was perfect. Did he have any qualms about this? None whatsoever. Napstablook was long overdue for a very thorough smooch, and Mettaton would be lying if he said he'd never felt like volunteering.

“oh… you will?” Blooky looked surprised. They also looked a bit teary.

“All you had to do was ask!” Mettaton guided them over to a sofa. “First, Blooky, dear, sit down. Close your eyes.”

“okay.” They sat there, hands working at the hem of their sweater, face tilted up. Mettaton laced his fingers through Blooky's and leaned forward till their noses were touching.

He pressed his lips to Blooky's once. Then twice. Blooky let out a small squeak. Mettaton laughed against their mouth and kissed them harder. “You have to kiss me back, Blooky,” he said, gently.

Blooky did their very best, he knew, but a gentle peck wasn't what they'd been talking about. Mettaton let go of their hands and moved onto their lap. “Comfortable?”

“m-metta?” They flushed bluer this time. “...yeah.”

He moved their arms around his waist and kissed Blooky again. Open-mouthed. He licked their upper lip, and they all but trembled. It was adorable. He did it again, and Blooky whimpered.

Perhaps he could be selfish this time. Mettaton pushed Blooky against the backrest and eased their mouth open with his tongue. They tasted like vanilla and cold metal. He could hear slight static building up at the back of his consciousness, and that made him ridiculously happy.

Blooky pushed him away, and he tried not to look as injured as he felt. “What happened, darling?”

They were teary again. “you really don't have to,” they said, their voice shaking.

“I want to,” he replied. “What then, hmn?”

It looked like Blooky hadn't even considered this. “oh.”

“And I'm going to make you pay for interrupting,” said Mettaton, lightly tapping his nose, his tone teasing.

“oh no...” They were blushing again.

“Oh yes,” sighed Mettaton, and he pressed himself against them, picking up where he'd left off, sucking at their tongue and running his hands over their sides. If their erogenous zones were the same-- he slipped a finger under the plate shielding his soul and softly pressed the walls of the cavity where it lay. Blooky made the most delectable noise, and he decided he needed to hear it again. And again.

“metta!” they gasped, clinging to him. “don't stop--” They whimpered again, and he couldn't help the feral grin he wore right now.

He kissed them deep, fingers kneading the soft cavity under the plate, enjoying the sweet noises they made. “Like this, darling?”

Blooky only moaned, their voice distinctly staticky, their cheeks and nose baby blue.

Mettaton worked his fingers harder now, hearing waves of noise in his own ears. They moaned again, and their voice skipped and shifted tones as they lost control of it. He caught it with another kiss, pornographic and hungry, timing them to the dips and crests of static he could feel running through him.

Then they pressed up, clumsy, needy, perhaps a little desperate. “metta,” cried Blooky, trembling.

Mettaton kissed him quiet.

…

Some distance away, Alphys had her head in her hands.

Mettaton must know that she'd kept motion logs of his body for the first few weeks. General debugging work, nothing more, but the logs were very thorough, and she was sure he remembered they existed.

Then again, wasn't it just like him to put on a show?

Well, Alphys thought, gleefully setting aside her logs, she was so aboard this ship.

Re: Mettaton/reader

I kinda doubt I'll get a reply this late in but - I am filling this and wondered if you had any preference regarding what bits the reader/MTT have? If not I'll probably keep the reader vague and go with my personal headcanon for MTT (which is that he has whatever he wants to have at that time - good ol' interchangeable parts).

Re: Papyrus/Reader/Mettaton

Jesus Christ, whenever you decided to have sex with Papyrus and Mettaton, this isn't what you expected.

Mettaton, who was sitting on your face, moaned wildly, practically forcing his clit into your mouth. His pink heart was dripping onto your chest, the warm fluid wetting your whole torso. Papyrus was deep inside of you, thrusting hard and deep, gripping hard onto your hips.

"Mettaton really seems to enjoy that cute little mouth of yours," Papyrus commented lowly, "You must be very experienced."

The robot chuckled, "Oh, I'm certain they are. Darling, we seem to be fucking a proper slut."

You moaned loudly at that, bucking up into the skeleton's thrusts. The two men laughed at that.

"Oh, darling, I think they like that kind of talk. You like being treated like a lowly slut, don't you?"

Oh, Mettatons voice was so fucking sexy. You wanted him to talk more.

"Oh, Mettaton, I love these whores you pick up for me," Papyrus said, "Always so desperate for what I have to offer. Pathetic, really.

Oh, you couldn't take this anymore. With a muffled scream, you came other Papyrus's cock.

"Did you just come? How humiliating! You really are a whore!" Mettaton giggled, thrusting harder into your mouth.

"Shit, who knew a s-slut like you... Could be so tight?" Papyrus groaned, "Shit, a tight little whore j-just for me and Mettaton, oh my God so tight and--"

Papyrus came inside of you, which caused Mettaton's orgasm, rubbing his cunt wildly against your face.

Mettaton immediately got off of you, while Papyrus lingered.

"Darling, are you alright? Do you need anything?"

You smile and give the robot a thumbs up.

"Ah, human..." Papyrus started, "Were you... Uncomfortable with the names we called you?"

You shook your head.

"Good! I, the Great Papyrus, am a master in bed!"

[(Anonymous)]

"Oh shit, oh fuck, Mettaton, I'm gonna--"

"N-no, darling, wait--!"

It was too late.

This disgusting asshole came inside of him.

"Burgerpants!" Mettaton shouted, softened cock still in his cunt, "You could have shorted me out! And what will Alphys say whenever she finds cum inside of me during inspection, huh?!"

The cat was sweating like crazy, anxiety filling him to the brim, "Oh, Jesus, I'm so sorry, ohh don't fire me, what should I do?"

Mettaton scowled, but soon lightened up with a brilliant idea.

"Burgerpants. Get off of me and put your face between my legs."

The employee complied.

"Now, bitch, I want you to get out all of this cum from my cunt. Eat out every single drop."

This was going to be absolutely beautiful.

Crack! Papyrus/any: genitals keep fading out

[(Anonymous)]

So. Papyrus is often pictured with a ghostie, glowing dong. But what if he isn't that good at conjuring it, and it keeps phasing in and out during sexy times? Cue much frustration from his partner.
