His sister Charlotte

Stroon on the floor of the changing room John quickly scrambles to his feet.

As he stands upright his eyes meet the shocked face of his sister Charlotte.

At first it's deathly silent as they both stare into each others eyes, but then his sister's eyes wander down below and the silence is broken with her excited laughter.

John looks and sees his shrunken nub of a member, it's barely visible and with the changing room air con seems to be even smaller than before.

Charlotte tries to talk through the laughter and heavy breathing.

"Oh... Oh my god John.. I knew... I knew you would be small but this is... To much.

She stumbles back slightly, trying to reign in her giggles while covering her mouth with her free hand.

John's face quickly turns red and he finally covers himself, trying to take control of his embarrassment.

"Charlotte enough, just give me back my clothes" with which John darts forward and tries to grab his clothes back with a free hand.

John's sister easily dashes back keeping John's clothes out of reach. And while still giggling and grinning from ear to ear.

"This is better than I could have dreamed, you loser. I need everyone to see that button dick of yours"

And with that Charlotte sprints out of the changing room into the store, leaving you with not a thing to wear or anything to show.
