Summary
“Ladies and gentlegerms,” it comes out in a semi-coherent slur, “kindly avert your eyes. The following material is not suitable for a family audience, as this is the part where I get rewarded for my excellent behavior.”
---
Tenna and Mettaton have had...-something- going on for a while now. Neither have put a name to it, nor have they pushed the envelope. An empty stage post-award ceremony provides the perfect opportunity to change that. -

Summary
Hiiii guys 😗🥲 it's been so long ya'll oh my gosh 😭😭😭
"
Getting a job at an aquarium was not something Gustav ever thought he'd be getting into.
He went to college, he studied culinary, he was great. But, y'know. Shit happens. Plans fall through. And you take chances.
So! When he stepped foot into that private area, he assumed it was some rare fish- although, while technically yes they are rare fish. Eeeeeh, he doesn't think.... that really counts.
Mermen.
Jesus christ what fucking dream has refused to loosen its grip on him.

Summary
He perched his forehead against Tenna’s screen, where TV fuzz tickled him. Breathe, he reminded himself. If he configured the settings correctly, then Tenna was allowed to be aroused, to feel everything twice as much. Paired with other physical restraints (no touching, no movements to assist Mettaton, and definitely no orgasms), this meant they could actually take their time.
Tenna did say he was game for anything, so long as it was with him.
There’s more to becoming a TV World co-host than simply signing twenty pages of a contract. There’s also a tradition to uphold after the pilot episode.

Summary
Tenna considers himself to be a seasoned family entertainer, a jack of all trades in the high-flying business of distraction. He knows what makes children laugh and mothers smile.
His new home has no children or parents. It’s barely a home at all, only a tiny room with an audience of one who is neither mother, father, nor child.

Summary
Monsters were freed from the Underground and Mettaton was very quickly considered one of the biggest celebrities in the world. But at what costs?
That's mostly Papyton fic centered around Mettaton, but there's also another relationship at the beggining (but papyton rocks)

Day one - Orgasm Control by YaoiAficionado

Summary
He was frustratingly unbothered by being filled so fully, so much so that Anthony began to wonder if he was truly as.. endowed.. as he believed himself to be. Mettaton had told him many times that his size was more than satisfactory, above average in all categories, tens across the board!
But if that was true, why was Mettaton acting like he was the size equivalent of a toothpick? At least toothpicks would be painful! This was nothing, no furrowing of the brows, no sweat, not even a wince every now and then. Stone cold poker face.

Or, Kinktober day one! orgasm control!
Yeah, sorry this is late definitely expect that in the future.

Summary
“I don’t know what to do, he didn’t even seem like.. upset, when I told him I was leaving for a month. A month! Does he even care?” He continued to ramble into his phone, pacing around his hotel room. It was a nice enough room, it had an amazing view, a large flatscreen and even a small kitchen (not that Mettaton was one to do any cooking). But he just couldn’t get into it. He hadn’t even unpacked into the luxurious walk in closet, instead choosing to keep his clothes in his multiple suitcases. The bed was too big, it just made him feel more alone, like someone was meant to share it with him.
If Mettaton was here filming a few months ago, he probably would have filled the gargantuan bed with an attractive Parisian fling immediately. But now, after the Anthony Tenna swept him off his feet (literally), he hadn’t sought out anyone besides the older man.

Or Mettaton goes to France to film, shenanigans ensue, they fuck anyway.
You need to read Summerboy (previous fic in the series) to understand this!!

Summary
Tenna was the perfect distraction- from the outside world, from others, and, most importantly, from himself. Because when Mettaton watched that TV, put himself in the shows, he could pretend he was someone beautiful, popular, successful. Not the loser he was. Not a useless nobody.
He was rotting away.
Tenna noticed.
(Slightly inspired by the movie I Saw The TV Glow).

Oh No! I'm In Love With My TV, But I Just Found His Ex In My Trash! by MMMOTH

Summary
Well, the world could’ve ended, but it didn’t. Now Lightners and Darkners live together in relative harmony, which is great, because Hapstablook’s new TV has turned out to be quite a lovely gentleman. Still, TV waits for no one, and while Tenna is off rebuilding TV Time for a modern audience, Hapstablook simply watches, yearning for a day when they can be a special guest.
And then a ventriloquist dummy gets stuck in Haps' trash, and things just kind of go downhill from there.

Summary
Tenna glanced back to ensure Mettaton wasn't seeing them.
The man jerked forward and slammed his hand onto the counter. "You ser—seriously DON'T recognize me?! Y-y-your old PARTNER?!"
"My—..." Tenna froze, his heart pounding hard enough to drown out the music. My old...partner?

Summary
A day has passed since Tenna settled into life with Mettaton- watched and appreciated, he's very hesitantly happy with this new, shaky life.
That is, until two certain kids get a little too curious, making the Knight have to set an example- or, perhaps, cause a distraction?
Originally a supposed murder attempt, Tenna can now walk around in the Light World, able to switch between ordinary TV and monster. Now he has to actually put the work into acting like a person, sorting through his trauma, and getting to know his new roommate. When characters from his past start making things more complicated, will he be able to handle the pressure? Or will he shatter for a third time?

Summary
“When are you going to kiss me?”
Tenna froze, antennae twitching as his screen cut out. “Beg pardon?”
“When,” he leaned in, “are you going,” his mouth just inches from the screen, “to kiss me?”

Summary
Mettaton and Tenna are Human. Drunk humans. And celebrities, though, Tenna's a bit... washed up, having been around for so long. Now, only his few exes and old women watched his show... so he needed someone to... *spice it up*. That's when Mettaton came in.

Summary
Anthony used to have people scream for him. Maybe not for a display as vulgar as this, but didn’t that prove how much better he was? He didn’t need to parade around a perfect body with ample curves to garner attention like Mettaton did. Anthony used his wit to draw in a crowd, while Mettaton abused the power of long legs, amplified by a dramatic pair of pumps.
He found himself drifting toward the makeshift stage that Mettaton had commandeered. For what reason? His brain didn’t supply an answer to that.
He just.. needed to be closer.

Or Tenna is a jealous prick but they fuck anyway.

However, Tenna is quickly proven wrong once they finally meet, and Mettaton isn't anything like he seems,
