As you gaze down at your penis, you notice that your balls are still tiny. Laughing at such a simple mistake, you whisper "I wish my balls grew to match my cock." You smile as a warm feeling envelopes your nether regions, and watch as the magic happens.
Your balls slowly start inflating, soon speeding up and reaching the size of tennis balls. You groan in pleasure as they grow larger, approaching honeydew size. You begin to grow hard, watching your balls grow. Soon they slow down and stop, being slightly smaller than basketballs. You do a couple of pelvic thrusts, and rejoice in the feeling of your balls clapping together.
You reach down and massage your balls, revelling in the warmth coming from them. You then move to your penis, stroking as much as you can. YOu continue to masturbate, your dick getting hard. You're basically panting from the effort, but are satisfied by the results. Your throbbing dick is rock hard, showing off a menacing four feet of seexual arousal. You give off a small yelp of satisfaction as you nut, splattering against the carpet.
You pick up the wand and begin to wonder about all of the possibilities. You're had an inflation/transformation fetish for a long time, and this was going to make your dreams come true. You grip the wand, and think of a list of transformations.
