"This is how you have to do it, you see, you need to lift your arms up like this..." Stephanie says while holding onto Isabel's arms and lifting them up. Isabel listens to what Stephanie has to say.

Little does she know, that Heather has snuck up behind her in a crouching position. While Stephanie holds Isabel's arms up, Heather grabs her shorts and pulls them straight down to Isabel's ankles.

"OH MY GOD!" Isabel screams, attracting more attention to herself while standing there with her panties on show and arms **** into the air unable to pick the panties up.

"Hahaha! Gotcha!" Stephanie and Heather laughed, and when the panties had reached Isabel's ankles, Heather pulled them backwards, tripping Isabel and making her fall forward. Heather then just whipped the shorts all the way off Isabel's feet, leaving her lying on her stomach with her panties on show and still being held by Stephanie.
