You could try something like this:

var clicks = 0;
$("html, body").on("click",function() {
    if(clicks === 0){
        funcA();
    } 
    if(clicks > 1){
        funcB();
    }
    clicks++;
}

Where funcA and func

Edit: I changed my answer due to your latest addition to your question. See this snippet:

var myFunctions = [];

myFunctions.push(function() {
  $("body").css("background-color", "red");
});

myFunctions.push(function() {
  $("body").css("background-color", "green");
});

$("html, body").click(function(){
  if(myFunctions.length > 0) myFunctions.shift()();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

html part :

<input type="button" value="Click Me" />

script part:

$("input").one("click",function() {
    alert("First Function");  
  $("input").one("click",function() {
    alert("Second Function");
  });
});
