[Finale of Kalvaring] Torahiko X Tatsunii/Tatsuki
You don't need to read the previous Kalvaring stories to understand or potentially enjoy this one, but you'll get more out of it if you have read them, especially the more recent ones.
When I first wrote this and posted it on Furrafy in Febuary (hence the Valentine themeing), I said it would be the last free Kalvaring story I ever write, and that after it I would only do them on commission. While that will be the case until at least December, it likely won't be the case forever, and I am greatly regretting saying it back then, as now I can't write the personal Kalvaring stories I recently started wanting to write without breaking my perfect standard of honesty a bit (worrying over that has caused me much stress). So here I'll just say that this is the last free one *for a long time* and that if you can't afford to commission me for a paid one in the meantime, you should write your own. I've posted 15 official example stories, which should be plenty for you to be able to learn how to write this theme yourself (hint: it's like writing Melding but rigid like armor rather than gooey, and normally only the inside person grows in Kalvaring).
As such, this is more like the Finale of Season 1 of Kalvaring, and you can expedite the start of Season 1 by commissioning a Kalvaring story from me or writing your own.

Morenatsu fanfic
Torahiko (voyik) X Tatsunii (gargen) Kalvaring affectionate fusion story
All characters in this fanfic are 23+ years old (and you should be too when you read it)
Wrote this during Valentine's season, so it has extra focus on romantic cuteness.
(This is set in the same AU as the previous Kalvaring stories with Morenatsu characters, so in my headcanon Torahiko is a polyamorous voyik and also spends plenty of very romantically cute quality time with his/voyikron other boyfriend(s) in the village before or after this story takes place)
Gonna use voyik* pronouns for Torahiko in this story since that makes disambiguating sentences less clunky.
Story:
Torahiko strolled up to voyikron boyfriend Tatsuki, or Tatsunii as voyik always calls him, inside his private cave, and said “Snug." while winking seductively. Tatsunii blushed deeply, knowing the intimate activity voyik was hinting at. Even after dating for many years, and having done that intimate activity several times before, it still felt like a really big deal. Maybe even more so than the first or second time, which were inevitably somewhat confusing, and thus not as thoroughly enjoyable as doing it yet again, now much more adapted to its peculiarities.
Torahiko gave Tatsunii a very tight bearhug, and sweetly whispered to him “I love you" in voyikron deep and smooth manly voice. Tatsunii whispered “I love you too" in his similar but slightly huskier voice.
Torahiko loosened voyikron grip just a bit so that voyik could rub Tatsunii's pecs and belly. Tatsunii reciprocated, massaging Torahiko's pecs. They put a significant portion of their strength into the rubbing, giving each other deep massages. And they both leisurely took their time with it, rubbing in big, slow circles. Then Tatsunii leaned down and passionately kissed Torahiko's pecs. Torahiko reciprocated, giving Tatsunii's pecs a deep kiss, then energetically trailed downward with a few rapid extra kisses, including kissing the top of Tatsunii's belly. To make things more fair, Tatsunii responded to this extra affection by lovingly groping and rubbing Torahiko's big biceps. This made Torahiko do a blushy little giggle. After all that, Torahiko temporarily stopped hugging him and started grandly twirling around in a way that showed off voyikron speed and manly strength, and then started circling around Tatsunii with the path of voyikron energetic twirling. The swirling of Torahiko's yellow fur looked almost like an electron in a diagram as voyik circled around. When Torahiko came to a stop, voyik tightly hugged Tatsunii from behind, this time hugging snugly enough to spark kalvaring. Since these two boyfriends have done kalvaring together several times before, the spike in their excitement for doing it was deemed sufficient consent by the spell, so it activated silently this time around.
Torahiko stepped forward into Tatsunii, anchoring voyikron legs inside his legs and hugging into Tatsunii's torso while sliding into his arms (in the fusion sense). Torahiko's abs widened somewhat and expanded greatly as they grew forward into Tatsunii's musclegut. Then Torahiko's muscular legs grew much thicker as they grew into Tatsunii's legs. Black tiger-stripes appeared on Tatsunii's legs, matching Torahiko stripes. However, no other coloration changes happened to either boyfriend.
Torahiko's very buff arms grew even beefier as they grew into Tatsunii's arms, and then similar to his legs, tiger-stripes appeared on Tatsunii's arms as an isolated coloration change. After Torahiko had fully grown into Tatsunii's arms and was snugly stacked within them, voyik generated and unleashed a small burst of empowering energy into Tatsunii that caused both boyfriend's biceps to grow bigger together. Then Torahiko's huge buff pecs grew forward into Tatsunii's pecs until they were snugly stacked together, and after that voyik grew their pecs much buffer with another burst of empowering energy.
At this point, Torahiko's paws and feet grew a bit chubbier as they grew into Tatsunii's paws and feet, and voyikron claws slotted into his claws.
Torahiko's buff shoulders grew into Tatsunii's shoulders quite quickly as they were very similar to begin with. Meanwhile, Torahiko's tiger tail slid down into Tatsunii's tail, the fluffy fur on it compacting at the tip while the base of voyikron tail grew wider, in order to fit properly and snugly inside Tatsunii's tail.
Finally, Torahiko's head grew up into Tatsunii's head, with Torahiko's ears rotating to poke out sideways into Tatsunii's ears, and voyikron neck grew thicker with muscle and chub as it grew into his neck. And Torahiko grew dragon antlers inside those of Tatsunii.
Now that Torahiko & Tatsunii were fused together via being stacked together extremely snugly, they started flexing in a unified way as if they were a single being. They flexed their extra big and beefy arms, watching and feeling their biceps peak together, and bounced their massive pecs, feeling the intense erotic pressure of Torahiko's muscles pressing up against Tatsunii's muscles from inside them. Then Tatsunii put his arms behind his back and stretched in a way that showed off his supporting muscles, which had also grown to keep his body balanced, and he took time to enjoy how the erotic pressure between him and Torahiko shifted around inside him as he stretched.
After a while, the fused boyfriends laid down to rest, enjoying the cozy warmth of their snug inside hug, which contrasted with the slightly cold floor of the cave, and enjoying even more so the emotional warm fuzzies of their maximally intimate romance that their fusion is a part of.
Epilogue:
Eventually, Tatsunii got up and looked around, pondering what else he and Torahiko could do together while fused. His gaze settled on a small stool in his cave workspace that he had left the Kalvaring Chemeray spellbook on. “It's gone…!" Tatsunii whispered in shock. No one could have swiped it away from this secret spot. “What is?" said Torahiko from inside him. Then Tatsunii said “The book. The book that gave us the power to kalvar each other." And then Torahiko said “Oh, that book. Well, it kinda just fell out of the sky one day, when it came into our world. Maybe it randomly went to some other world now, and has just now fallen next to another loving person who will share its affectionate fusion with his boyfriend."

Maybe, just maybe, it has fallen into your world, dear reader, and is about to be picked up by a representative voyik of your world, if it has one…
If so, I hope to someday hear your legend of Kalvaring <3
