This is pretty good.

And original too.

S.A.C.

“You’d think everypony would had heard of it by now, it’s been legal for over six hundred years,” Twilight drolly corrected her. “Love triangles, love squares, love dodecahedrons, love n-drangles, it really doesn’t matter, it’s perfectly legal. So I finally cut them off and told them, ‘Look, I… I really don’t understand what the problem here is, if you’re all so in love with each other, why can’t you just all be together? I could perform a marriage right now.’ And obviously they’d never read a history book either because they just sat there, stunned. Well, they were stunned, for a minute, until they started praising Equestria and falling into each other’s hooves… sheesh, you’d think ponies would have the sense to at least make the trip to an Inn first.”

Yeah that's all going in my head canon for love ethics in Equestria. Fits so perfectly.

Lovely start to this series.

The prequel was actually one of the very first stories I'd heard from this site, after finding a reading on YouTube. It's one of the things that drew me here in the first place. Knowing there's a sequel is quite exciting, especially now that you've set up the legality of polyamory. We can all guess where that's going, but I'm equally excited for the journey.

More please :o

Threesome with smaller(but still pretty big, they can handle it) Spike.
