Summary
“True, but it’s damn convenient you just happen to have this experience that no one knows shit about.” There was an accusing glint in Red’s eyelights. “Right when tryin’ to talk about how mature ya are. Ya can’ even give me simple answers.”
And Blue didn’t know what it was; if it was the stress that had just built up from everything that had happened combined with Red’s degradation, or if it was the hidden challenge in Red’s words paired with his indifference, that finally pushed him to the end of his limit and broke it.
Within a blink, a growl was echoing from behind Blue’s gritted teeth, and his hands were suddenly on Red’s shoulders as he slammed his chest against Red’s and boldly pushed the broader monster down, pinning him into the frayed and worn cushions beneath them.
Red looked ready to strike, red mist billowing out of his right socket, before Blue leaned in to hiss right against the side of his skull. “Do you want me to prove it?”

Summary
“You’ve gotta be shittin’ me.”
Honestly when Edge had said having something to nurture and distract could help him deal with his ‘separation issues’, the last thing Red had expected was the bitty center. At most he’d thought he was going to be forced to buy a plant or two.
Not pick out a damn pet!

Summary
Red (Underfell Sans) thinks his long-time crush Blue (Underswap Sans) is up to something. If there is a secret to be sniffed out, then call Red a hound dog and put him in a collar- well, maybe not that last part, his neck might come in handy later.

Summary
Doctor Frisk is given a new job (after their last one nearly ended) of watching two skelemers. There has been an egg thief haunting about the place, and the two in question are expecting their very first-and, if things go wrong, potentially only-pup soon enough, making them a target for the thief.
Doctor Frisk will, of course, take this role very seriously.
They just have...a few other things they have to work through.
(A story primarily about Red and Blue and their baby, and kind of sort of about a human's dark secret they've carried with them for years.
But, well, you know, who cares about that! Baby mer time!!!)

Summary
Blue is a beautiful halo of light, a jellyfish-like mer whose soft underbelly belies his strength. Electricity and rage courses through his leylines, and a sharp beak hides under the beautiful, dress-like furling layers.
Red is a squat, slightly pudgy red-tailed mer, who is unable to tolerate much light. In the dark of the deep sea, his tail glows, spotted by a trail of glowing marks, with a bouncing light above his head mimicking a lantern fish.
They have been mated the moment they became of age, entwining fates that last them their entire lives.
This is but a collection of their tales, from the beautiful and lovely, to the gruesome and strange.
After all, they have a whole ocean to fill with their tiny pups, and all the time to do it in~
(AKA: Author made mers into a prompt fic. they gonna fuck. have lots of babies. we'll make it SO romantic I promise, just stick with me-)

Summary
...Though... well... it's just... Blue had spoken so highly of Red! He'd put in so much effort into that relationship, because he put effort into all his relationships. So it just felt embarrassing how abysmally wrong he was. Terrible judgement of character.

Or,
Blue is very happy with his relationship until he's not. But it's going to be okay. -
