This story takes place a few months after the 3rd movie in the outskirts of the secret Panda village. Po finds a note from master Tigress and what happen soon afterwards starts a lusty and growing chain of events that will make both love and weight grow to massive sizes!

Title should be "Massive Masters" according to the artist's page. I see you claim to have written the story for this*, so you might want to ask the artist to change the name if you prefer this one.

If it helps I've made it a double titled comic so both titles are used.

"And then Po and Tigress lost their footing and rolled down towards the valley, causing a violent landslide in their wake that killed all of the pandas in the village as well as themselves. But the growth serum kept working on their already-decomposing corpses, and they grew and they grew until the planet was engulfed in Po's fat ripples, ending all life on Earth and sparing all mankind of the horrid fate of being pulled towards the sun by the now-excessive gravitational pull caused by the black and orange celestial bodies. The lovers' fetid corpses sizzled in the star's photosphere, incinerating whatever it could before engulfing what was left of their charred and boiling remains into its core, kickstarting its collapse in on itself before ending our solar system in a brilliant but obliviating supernova. The end. Literally."

It's not often I say something like this... but this has zero redeeming qualities. Speaking as someone who's into a fair bit of random and inexplicably fucked-up shit, I cannot possibly understand how any living breathing human being can be even remotely attracted to or even aroused by this sort of thing.

Well, apparently they went full on FAF(You know, the guy behind Hetty?), all they post are teasers for their patreon, and threaten action against those who share them
