Text hidden by button?

[CFSSEO]

The issue: text on a page available only  by pushing a button or clicking Read More and the text slides up via AJAX.

Will Google penalize a site doing that via hand edit?  I think that according to Matt Cutts, as long as the text is available to the user then it's ok.   I want to double check on this.
