Trouble in the vents

Jessica was too eager to get out of the vent to realise that it was slowly dipping downhill. As she put her right hand down on the cold metal floor, she slipped and slid face first down the vent's chute. She plummeted into the building, through the vent. Jessica tried not to shriek, but the sudden slip had caused her to yelp.

The sliding came to a stop, as the chute bent back to a horizontal position again. Jessica had a brief moment of relief, as her adrenaline had shot up. She rose to her hands and knees, her back basically touching the roof of the vent. "I fucking hate air vents!" She complained again. She suddenly heard a small ticking noise, like a bunch of screws coming loose.

Her concerns were soon answered, as she'd landed on a vent grill door which couldn't handle Jessica's weight. With a sudden jolt, the door gave in and swung open. Jessica fell down into the room below her. "OOOOMPPHH!" She yelled as she smacked onto the soft floor.
