My kitten keeps licking my eyes!

Hi everyone,

So for the last 2 or 3 days, my kitten Roky has been trying his absolute best to lick my eyes.

When I pick him up, he purrs, puts his paws on my shoulder, sticks his tongue out and nuzzles/sucks at my eye (which I keep shut, obviously ^^).

It might sound a bit daft, and maybe I’m worrying over nothing and it’s just a sign of affection, but I’m scared he might accidentally bite or scratch my eye...

I’d like to know if I should let him carry on or not, and if any of you have had anything similar happen? ;)

Thanks
