Chase after her

John couldn't give his sister a moment to get ahead, and started running after her at full speed.

John tightly clamped his hands over his groin and sprinted through the changing room door, right into the clothes store itself.

Initially John was a little disoriented, glancing around trying to see where his sister went.

Soon John heard snickering getting louder and louder. Looking around he could see multiple girls looking at the naked man who just burst into the centre of the store.

Some girls where giggling , while others just stared with their mouths ajar. And a few sneakier girls started to take photos of this spectacle.

John's face was getting more flustered and embarrassed until his sister's voice caught his ear.

"Hey little man, forget something?"

Charlotte was leaning against the frame of a door, still giggling and smiling intently while dangling Johns underwear on the end of her finger.

Without a moment to think John ran at his sister. One hand outstretched while the other tried to hide his modesty.

But for Charlotte it was all to easy. As her brother leaped forward she shifted her weight and leaned out her leg tripping John effortlessly through the door. The door then shut leaving John locked out, allowing Charlotte to take her brother's clothes, mix them into the stores clothing racks and then casually walk out the store with the most devilish of smiles on her face.

Eventually John started to gather himself and pick himself up of the floor.

His heart sank as he saw where he was.
