They should make a new tag called "marshmallow hell," which denotes any picture in which a single character is being smothered by one or more pairs of breasts.

He can still breathe, so it's not really smothering.

And now that that has set in, what would be the ultra correct form? :(

I don't think you understand.
That should be, "marshmallow HEAVEN".

Also, there is already a tag for this, "breast_smother".

That's not Asuka...
