This looks very promising. I'm not sure I can read it during NNN, though, if those first few paragraphs are any indication.

NNN is a ploy by crazy conservative prudes! Don't fall for it!

Cum bath in its literally meaning... That new Damn if Shining Armor is that mutch of a Stud... Equestrias mare population will increase there foal production soon

but not like a stallion’s cock, not in gay way, if that made sense.

woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooow
Aside from this one pretty jarring line, this was a good read so far!

It's Shining Armor, not me!

She ... simply walked right in, her forelegs disappearing into the opaque water first and the rest of her body quickly following, until her long alicorn neck rose above the surface like a swan’s. “Ooh,” she said appreciatively, “It’s so rich and creamy!”

…..Don’t tell me it’s changeling cum.

Despite himself, he shuddered again. “It’s not easy...” Besides the still-unfamiliar – and quite intense – feeling of her working through his new feathers, there was also the matter of her magic touch down below, gently stroking up and down his shaft while also tingling its way around his balls.

...Of course she does this.

“I know you’re nervous, but you’re an alicorn now, and that means something.”

How did that happen, by the way?

“It means I have to ... take a bath with ... her?”
Cadance laughed a little, brushing down his flank as her magic kept working underneath him. “Oh come on, now. She’s not that bad.”
He looked at his wife sternly. “She’s going to try to have sex with me!”

Cadance: "Hey, it could be worse..."
Shining: "What? How could it be any worse that this?!"
Cadance: "She may not try to have sex with you..."

“Um, honey,” he said, “Don’t you think we should do something about this first?” He turned sideways toward her, making his ardently hard cock abundantly visible.
“Oh not at all!” She giggled. “Chryssy will love it!”
“Cadance!” he called, but she was already trotting out of the little room.

Don't look like that, Shining! She is completely right!

Something says me there is still more about the bathing water we still have to learn...
(Changeling cum?)

I like the idea but I would have liked if they actually did serious political talks while making out. That juxtaposition always is fun.

Oh man ... that kind of stuff is difficult to write, though.

So, how did Shiny become an alicorn, again?
