Black to move
White and Black collaborate with the aim of white stalemating black on white's 14th move [help-stalemate in 14]

Basically an exercise in lining up black's myriad pieces for efficient slaughter by the lone king.

The white king moves last (causing the stalemate)?

Yes.

Hint: the f2 pawn must be captured sooner rather than later.
