Who are they licking?

My money is on Marisa... the most probably one for their affections.

The tags on Pixiv don't say, but one would assume Marisa.

Or it could be Patchy and she has a really flexible spine.
You never know in Gensokyo.

I sincerely doubt it would be Patchy -- all that time surrounded by books, and her avoiding sunlight for 100 years would probably ruin her flexibility, not improve it.

Well, except for the flexibility needed to fall asleep atop and amongst a massive pile of books, as we have seen in many other pics...
