Make a two keyframe animation, with the first keyframe being titsize 0 and the second titsize 100. Enable normalized time in the state of a one-state layer with that animation. Make a float for that titsize and control the float with a radial puppet. This will give you a tit size slider. Normalized time controls the position in a animation by a float value, with 0.0=0% and 1.0=100%.
