Protag to Buff Otter TF
#1 of TF Stories
A very buff and tall (but otherwise kinda generic) Otter man kisses the much shorter (but otherwise kinda generic) Humanoid protag,
and that kiss has a transformative effect, causing the protag to TF to physically match the Otter man.
(Essentially, an affectionate version of assimilation themed TF)
I watched as the beefy Otter guy in front of me bounced his huge pecs and casually flexed his massive biceps,
his boulder shoulders rolling mightily when he shrugged, unsure what exactly what was going on here.
Though many people might be at least somewhat intimidated by how much larger he was than me,
I was merely pleasantly impressed by it.
His gentle gaze showed that he meant no harm, and I was just as proud of being small as he was of being big.
And we held the mutual understanding that such is how it should be,
even though that understanding was abstract and unspoken.
After we stared at each other for a while, he suddenly leaned down and kissed me passionately on the lips.
I could feel his essence start to flow into me like a river; a flowing stream of manly energy.
His beard tickled my face as we kissed, and where it did,
the energy there gently prickled out into a fluffy beard that matched his.
I started softly rubbing my beard against his, and he dove his tongue into my mouth for just a moment,
licking my tongue just enough that it morphed to match his.
He retracted it as I recoiled in starlement,
but then his entrancing soft gaze made me forget about that,
as well as several other things that had grossed me out recently.
As suspicious as it might seem at first,
the forgetfulness he caused me was exactly the kind of therapy I needed these days.
I reached out and hugged him in gratitude, and as I did, he bounced his huge pecs against my chest.
This caused his manly energy inside me to flow into my chest and start growing my pecs to be as big as his,
which would take a little while, considering the size difference involved there.
Getting excited by this, I hugged him tighter, so he would rub more of his massive muscles up against me.
He rolled his abs up against my musclegut, causing it to morph into eight pack cobblestone abs,
and he flexed his biceps up against my musclechub arms,
catching them in the crook of his arms and making them grow bigger and harder with sturdy muscle.
As our arms were entangled, he rolled his boulder shoulders,
causing my shoulder muscles to bulge outward with rapid growth.
As my muscles grew to match his, my fur also grew a lot thicker,
and was tinged a more orangey shade of brown, as it became Otter fur.
My now massively buff body slimmed down a bit in terms of chub, making it more streamlined,
and thus at least a bit better for swimming, as an Otter's body should be,
However, with this much impressive muscle bulk,
I would still be much more advantaged at strength rather than grace, even in water.
But agile and graceful swimming was definitely the type of honorable job that I was happy to leave to
the type of incredibly slim Otters who were known for that.
Suddenly, an adorably small Otter tail grew out of my back.
The thought of it made me giggle in a giddy way.
Finally, in much the same way as with the rest of my body, he caused my leg muscles to grow to match his,
which came with a significant height increase as well, as my legs grew to be as tall as his.
I thanked him with deep gratitude, and he merely responded by kissing me again,
more softly and respectfully this time.
I hummed happily into the kiss, and we embraced each other while kissing for quite a while,
sharing in the specific kind of intimacy and joy
that can only come from sharing the same form via transformation.
And that is the story of the day I transformed into a buff Otter...as an affection session.
