My cooldown keeps getting bypassed?

I have a sword ability but when you spam R it keeps playing completely disregarding the cooldown, can someone help me?

Local Script inside of tool

local UIS = game:GetService("UserInputService")
local controls = require(game:GetService("Players").LocalPlayer.PlayerScripts.PlayerModule):GetControls()

local Equipped = false
local Cooldown = false


script.Parent.Equipped:Connect(function()
    Equipped = true
    print(Equipped)
end)

script.Parent.Unequipped:Connect(function()
    Equipped = false
    print(Equipped)
end)

while true do
    wait()
    if Equipped == true and Cooldown == false then
        UIS.InputBegan:Connect(function(input)
            if input.KeyCode == Enum.KeyCode.R then
                Cooldown = true
                game.ReplicatedStorage.Parry:FireServer()

                controls:Disable()

                print("Player press R")
                wait(3)
                controls:Enable()
                wait(5)

                Cooldown = false

            end
        end)
    end
end
