Question re BBJB (not sure about if I abbreviated correctly)

Is is crazy to expect a provider to do this w/out a cover?

It's all a personal comfort thing.  I've had cbj's and bbbj's.  The bbbj is better.

If she doesn't perform a BBBJ without a cover then it's not a BBBJ; it becomes a CBJ!

IOW, a BBBJ HAS to be provided sans cover.
