*he is trying not to crush! but he's starting to get the urge to push, and it just... comes naturally when he bears down and pushes, taking a deep breath afterward, surprised at the lack of control he has over anything - his water has finally broken and there's a gush of fluid onto the towels, but he barely notices anything at all*

I'm... I'm breathing... and p-pushing. Is that... right?

*and more pushing goes here*
