Cadance is more of a mare who enjoys being cucked.

Thats….. not how bestiality works at all lol

@Background Pony #BC1E  
if there ponies fucking ponies no

arent all of them beastiality?

@Claw  
I agree

I am not sure about the others, but I think we all agree about cozy glow here.

To be honest I would expect more of:  
Fluttershy - bestiality  
Rarity - bondage/bdsm  
Cadance - Mommy play
 
sounds a bit more logical in my opinion

I don’t know. Fluttershy is very introverted so she would more likely want to have sex alone. I would imagine her more into bottomplay. Where she is allowed to be weak and helpless.

Interesting choices. I would think of them very differently. I would think twilight is more into femdom as she wants things to be done ‘properly’. It is also a pretty diverse thing which Twilight would love because it gives room for experimentation. Twilight is scientific by nature and science is all about experimentation and improvement.  
With Pinkie and Rarity I would switch them around, Pinkie loves being a mommy and Rarity is so self-concious that she would get a huge thrill out of public use.  
Applejack would be power bottom I think. Seeking a respite from the stress and responsibility. She hasn’t been groomed for leadership since foalhood like Twilight has so it’s not as ingrained into her.
 
With Celestia I would imagine spankings more. It’s something that gives her more options to play with and she get’s to bring her maternal side to the forefront.  
With Cadance I would think more bondage or very varied. Cadance is a horny mare and also a highly intelligent one so she would love to experiment and do all kinds of things. Twilight is also intelligent but she is not as horny and also her ideas of ‘proper’ hold her back, she also needs to put it into some kind of rational frame. Cadance just does whatever she wants and it’s more her short attention span than her curiosity. I’ve always seen Cadance as a older and slightly different version of Twilight. Just as diverse in terms of interests but also improvisational and intuitive. In contrast to Twilight who is structured and rational.
 
Cozy glow would likely be into bondage. Domination without any restrictions.

Yes

Shouldn’t Rarity be more fitting for femdom?

fluttershy should be bestiality

Celestia IS face sitting. >:3

Uh, not how I envisioned their fetishes.

I don’t get it
