NUT

Double pussy fingering, or maybe fisting for the one for other fingering

Diaper them

Have some fun with them.

If they’re okay with it, I’d screw both of them :)

Flip a coin.

@Amethyst_Crystal  
Jeez who hurt you? Its a joke

@Scrounge  
that’s because everyone in equestria is in heat

Given the context of the image, nothing.  
They’re pretty clearly not intentionally ‘showing their ass’ to anyone.  
They’re pretty clearly performing stretches or other such exercise.
 
And any bastard that presumes otherwise can go rot in fucking detention at the very least.  
I would then lecture said bastard and determine if they’re a dumbfuck, and I would say:  
‘just because someone does something nearby, doesn’t mean it was for your benefit’.  
Said dumbfuck bastard would also be reminded that the fucking world does not revolve around their stupid penis.
 
Oh wait, I guess I was supposed to make some kind of impressively crude lewd gropey remark.  
My bad.

I would ask if this is a prank.

Seriously, though, I wouldn’t read too much into it. It’s Equestria, everyone waves their butts at each other.
 

 
It’s literally how some of them say hello.

Looks like it’s time for an Oppa Gangnam Style reference.

They kinda are making a similar posture as RD

Or, is this about them showing me donkeys? I’m confuse.

Give their tails some tugs.

Supprise cuddles :3

Wave my butt back at them.

I would deeply lament my status as a phonograph, specially under the circumstances.

Begone THOTs!

Wonder why they’re mooning me.
