Susan picked up Jared's boxers.
'Well if you wont decide then i will!'
ZAP! There was a flash as susan began to change.
Her chin became masculine as her fine wrinkles began to vanish.
She began to look younger, yet not attractively so, more manly than before.
Her shoulders broadened slightly as fine hair appeared on her arms and legs.
'Cool' she said in a deeper voice.
Her boobs shrank, her large female breasts deflating, leaving her with a boys chest as her legs and arms filled out.
She looked just like Jared.
'Im you!' she gasped, looking down at her body, 'Well almost.'
Jared and Susan both stared in amazement as a tiny ball sack appeared between her legs, followed by a tiny penis inching out.
Hair grew around her dick and balls as her penis swelled a little then stopped.
'Is that it?' asked susan, shaking the limp little pecker, 'Doesnt it get bigger?'
Jared blushed as he shook his head, 'Im afraid not' he said, humiliated that his aunt now knew he had a small cock.
