Summary
Once the credits rolled, Tenna readied five other channels for their next feature. Mettaton kept him on his toes. Best to be prepared.
Except not that night. No, he never reached for the remote control to browse his options. Mettaton simply lounged in bed, avoiding the television screen. And he threw Tenna a different kind of plot twist.
After back-to-back broadcasts to keep his new Lightner entertained, Tenna finally gets a break—and watches Mettaton perform instead.

Summary
Miserable with the loneliness that haunts his being, there is little left that Mettaton looks forward to in life. No calls, no texts, no visitors. Trapped in a form that causes him anguish, he can't bear to venture outside again, especially when the therapist he'd confided in two months ago posed a rather confronting question about his desire for a body to call his own.
He feels no choice but to resign himself to his bitter reality.
From the security and safety of his living room window, he catches glimpses of the outside world as his neighbours head home from school or work each afternoon at three. But the weekend's just started, and with that, he knows he'll be lonely once more. He's so deeply tormented by it all, he can't bear the thought of attending Hometown's upcoming festival. So when he's gifted a second hand television by Kris and Susie out of the blue, Mettaton takes it as an ample opportunity to excuse himself from the event.
But he can't shake the thought from his mind. An off-hand comment the girl had made about blades and determination.
Is there really a way he can attain the reality he desires?
And if so, just how desperate is he to protect it?

Summary
Tucked behind a backstage curtain, Tenna made himself comfortable within an alcove. Out of sight, yet within view of Mettaton’s musical number. Barely sang the opening lyrics, and the anticipation dared to short-circuit him. A shaky breath slipped out while admiring Mettaton. Oh, how he longed to nestle between those legs and discover what other melodies he’d sing. That thought set off a spark and begged him to do something other than idly spectate.
Despite his efforts and best judgment, Tenna caved in.
Tenna tries to restrain himself while watching Mettaton’s stage performances. It goes as well as one would expect.

And I Swear That I'll Always Paint You Golden Days by Mattonious (OfficialMettaton)

Summary
"You're never a bother to me, darling. Every second of every moment with you is a pleasure I treasure, and I'd love nothing more than to ease any and all burdens you might have - tonight, tomorrow, whenever and wherever."
Tenna feels lightheaded.

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
It's their own private joke. Their little hush-hush. A mutually assured, closely kept secret: Those censors are thrilling.
They've played with the settings. My, oh, my, how they've played. Off again, on again, a little slip of Mettaton's fingers on that switch to cut him off just long enough to hear that strangled yelp and bring him back again.
The tricky thing is, they create an absence of. That switch has no advanced settings. No filters. It's all or nothing, which can only take them so far. There's nothing to fight against. They are there, or they aren’t there, and that's all there is to it.
It just won't do.
Mettaton wants him straining.

Summary
I had this funny idea about Tenna making his display glitch out until Mettaton changes the channel while Mettaton is watching stuff on him that he doesn't like hahaha! As a treat, I may add a second chapter that includes smut because the tag needs more smut 😈

Summary
Between set schedules, filming, script readings, proof-editing, dress rehearsals, and his own hang-ups about those star-studded events, Tenna rarely makes a public appearance. This time, though, there was no saying 'no' to the offer of a lifetime: an extravagant, exclusive invitation to an all-expenses-paid gathering of high-profile award winners.
Mettaton and Tenna find themselves in the same limousine, where their first meeting takes a sharp left turn as they find themselves caught dead in the middle of an assassination attempt.
Real drama! Real bloodshed! Real Pippins! Real... Feelings?! Scrap that last part.

Summary
I don't usually do this stuff but the ovulation won. Not really a plot? Maybe a comic here or there? This is just a collection of spamtenna (maybe with an occasional feacher) doods so don't expect full works. ALSO I don't know how anatomy works so just assume it does alright? Alright. Also Also I will not be uploading often, and dont count on me to remember to mark this as finished in the future. Proceed

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).

Summary
Perhaps this was a good sign. A step in the right direction and away from his downwards spiral of uuuggghhhh. Because the way Mettaton saw it, he now had one of two options.
One: retreat to the lukewarm comforts of a lumpy couch until he became one with the cushions and waited until the inevitable heat death of the universe collapsed onto him to finally end the soul-crushing boredom.
Or two: watch whatever the hell was on his newly acquired TV.
Alone and bored to death, Mettaton looks for a way to pass the time while the Internet is down. Good news, he does. Bad news... uh, it’s totally normal to want to kiss your recently acquired TV, right? (asking for a friend, haha...)

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
In a city that never sleeps, Tenna tries to keep control of their life while the lights of the show force them to smile. But behind the scenes, a conversation with Spamton stirs old wounds and secrets they thought were buried. Between the pressure of the cameras and sharp words, an unexpected tension arises with Mettaton — a silent game of glances and half-truths. Nothing is entirely honest, yet nothing is completely false. In a world where every gesture is watched, one wrong move could change everything.

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.
