Take those balls up into your hand now. I want you to start giving them little squeezes. Push them together, let them rub up against each other for a bit. Two little bodies of lust, rubbing gently together, producing such wonderful feelings...
Squeeze them harder now. Just enough for it to hurt a little bit. And yet it feels so good, doesn't it?
Harder now. Much harder. Make yourself feel it in your stomach.
