Lick: Gabby  
Rub: Apple Bloom

@Caroo  
Caroo, you just won this… :D
 

Applebloom = Kiss, Blooms soles are tough to break through tickling, but the sweet and lovey-softy stuff, that breaks her down into a squirming, whimpering sweetheart.
 
Scootaloo = Nibble, Even that’s enough to make poor scoots hypersensitive soles flare up in ticklish torment. Of course you can claim your not tickling her, so the 2 minute rule is out the window.
 
Sweetie Belle = Suck, Sweetie’s crushingly sensitive toes wont last long under such duress. Soon shes begging you both to stop, and never stop. Poor confused thing.
 
Babs = Rub, those broad, large soles need some TLC, something sure to make her a happy earth pony and want to return for more
 
Gabby = Lick, because I bet they’re finger licken Good. ;)

@Alexlayer  
I extend my tongue in your general direction. :P
 
And if you do them juuuuust right, all five of those actions can be delightfully tickly in their own ways. ;)

@Yet_One_More_Idiot  
Boring!

@Alexlayer  
Not an option in this meme. :P

How about, tickle them all instead?

Kiss + Suck Sweetie Belle  
Nibble + Lick Scootaloo  
Rub Apple Bloom

Lick Scootaloo <3  
Suck Babs Seed  
Kiss Gabby  
Nibble Sweetie Belle  
Rub Apple Bloom

I wish Gabby’s were paws.

Can I kiss all of them? Doesn’t say anything in the rule book that I shouldn’t do one to all of them.

Are they clean?

I Kiss Gabby, Suck Babs Seed, Nibble Sweetie Belle, Lick Apple Bloom, Rub Scootaloo!

@Yet_One_More_Idiot  
You can’t judge me harshly for being loyal to only one. I am picking Babs Seed for whatever she desires and gladly letting anyone else take the others for them.
 
Sorry, but I am that loyal to my waifu.

Kiss Scootaloo
 
Suck Gabby
 
Nibble Apple Bloom
 
Lick Sweetie Belle
 
Rub Babs Seed

I choose to tickle them all.

@raakamagna  
Now you’re just being picky and deliberately misreading what I said, so I’ve clarified it a bit in the description. Nertz to you. :P
 
Each girl must have her feet pampered. Which girl gets each form of pampering?

I must choose one for each? I choose Babs Seed on all then. I mean, it never said I couldn’t repeat choices, and I love her so much!

@Background Pony #7A99  
You’ve got five actions to match, one-to-one, with each of the pone-girls. And you went and picked an action that’s not even available. :P

I’m picking Applebloom and i’m tickling her soft soles.
