What's the best way to make a sword like this?

I want to make a sword that will lunge when the mouse is pressed and will swing when released? This is my first approach but swing animation sometimes plays even if lunge isn't played yet. I'm really struggling with this. You can run this at Roblox Studio to understand what I mean.

script.Parent.Equipped:Connect(function(mouse)
	
	mouse.Button1Down:Connect(function()
		if not debounce then
			debounce = true
			lunge:Play()
			debounce = false
		end
	end)


	mouse.Button1Up:Connect(function()
		if not debounce then
			debounce = true
			lunge:Stop()
			slash:Play()	
			wait(1)
			slash:Stop()				
			debounce = false

		end
	end)
end)
