Balancing act

You asked the goth girl who you found out was named Kat to stand still. You found a plate and perfectly balanced it on her head. Then a cup and for the final trick you had laid the bra across the cup having stolen it from her shirt. Kat coildnt look now as her pierced nipples poked through the shirt. The whole crowd was chuckling to themselves. The next moment after another small tickle in your mind the audience's attention appears to have shifted to you. Looking down you realize your pants are gone showing off your boxers. Confused you simply ised magic to make them appear and as quickly as they are back on you forget the encounter entirely. Focusing back on your performance you must decide what your next trick shall be when you feel a phantom vibration slide along your cock. It extends from your balls to your tip before it is gone. Shivering you shake the feeling before continuing your act.
