Twilight: Neck nuzzle me, you giant demigod waifu! I deserve it! 💕
 
A gif so kawaii, I had to comment twice.

Celestia: “Who’s a good little kitty? Yes, you are!”

Only 21 items tagged with “affection”?
 
There should be a lot more! I know that the word “affection” isn’t a particularly commonly-used word, but this tag should be much more common! Most pictures tagged as “shipping” would qualify, but even then it wouldn’t be redundant! Considering that the term “shipping” seems not to refer to what is happening here.
 
People should tag more things with “affection”, and maybe also use “affectionate” or get “affectionate” merged with “affection”!

I want to be neckhugged by ’Lestia. <3 :3

Yoda: “Such a spoiled cat, Twilight is.” :3

Princess Celestia: “You’re me bitch, Twilight.”

Oh my gosh, look at it closely and you will see, how that star would actually poke right into the eye of celestia, so, what YetAnotherBrony1 posted, is pretty accurate!

This is pretty old…
 
…but still very cute.

It’s probably something all Celestia’s students will learn quickly. Maybe it is the real lesson zero?
 
“Position yourself like this, and Celestia will automatically hug you.”

@The Smiling Pony  
bit of both plus this is twi,  
celestia has probably been the best teacher you can have but twilight would worry about doom anyway.

It’s kind of weird how Twilight knows exactly what to do get hugged by a pony as unique as Celestia, yet still fears she’ll enact some horrible punishment on her over being late on her homework or misplacing her pet.
 
(Or we can handwave it as something foals do with their parents)
