Rapid double input to trigger second action causes uncontrollable spamming?

I’m trying to have right and left kicks in a row. Imagine games like Rockman X8 where you rapidly tap twice directional buttons to dash.

First kick is not a problem, only after the kick animation is completed does it allow kick button to be pressed again:

2nd kick sadly rapidly spams when the kick button is pressed more than twice.

I need the 2nd kick when the animation is playing to disable both 1st and 2nd kicks. I want to be able to “spam” 2nd kick rapid double input without spamming more than one 2nd kick animation, and disabling 1st kick animation when current 2nd kick animation is playing.
