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.
