Shelf stackers

You head towards the back of the store where a boy and a girl are busy stacking shelves. Glancing at their name badges you learn they are Ben and Jessica. You watch them for a few moments before deciding on a good way to start the ball rolling.

Jessica climbs up onto a small foot stall, lifting some boxes of cereal up onto the top shelf, and as she stretches her arms completely upright you click your fingers.

The button on her uniform trousers snaps off, bouncing against the boxes on the lower shelves, but that's not the most interesting part. With nothing holding them up any longer her trousers suddenly slide, dropping down as low as her knees. Stood behind her, you and Ben are both treated to a view of her arse, clad in nothing but a pair of cute pink panties.
