Drop down

You decided you wanted it over with quickly. With how small these panties are, they would probably rip in a second no matter what. So you step onto the chair and hook your legholes securely over before dropping down.

"Aaii!" Your squeal fills the room rather than the rip you had been expecting. Your ass was dangling several inches away from the seat, held in place by the cotton buried deep in your ass. The front had slid between your lips and was now crushing your pussy. You groan and hold your aching pussy knowing nothing is going to relieve the pain in your aching, chaffed ass until these things rip clean off.

"Now get started on the papers!" She demands, slaming the large stack down on your lap, pushing you lower down and forcing the cotton further up your delicates, before pulling a chair over to watch you squirm. Begrudgingly, you move the papers to your desk and get started. Leaning foward to write, you squeal as your panties dig deeper into your pussy. Unsurprisingly, it's very hard to focus on your work. If you don't finish before your panties rip, you were in for a hell of a punishment. If you did, you were in for a reward.
