"Ah!" you cry out as she gives a sharp tug to the front of your panties. You recover quickly as she brings her hand down pulling the fabric out from between your lips. She then begins the slow pull on the front again. Even with your clit a little more tender from the previous yank, the slowly increased pressure still feels nice. You start to moan again enjoying this mix of pain and pleasure. She continues pulling the front of your panties higher reaching to your boobs. She holds here and you squirm around trying and failing to free your clit from it's compression.

Her other hand grips the back of your panties now. At the same time, she launches the back upwards and lets go of the front dragging the fabric between the lips of your wet pussy. Your knees give out but she uses your panties to keep you from hitting the floor. With all your weight being supported on a thin piece of fabric in your pussy, you scramble to get your feet back under you and stand up.

Still holding the back of your panties in the air, she grabs the front again. She begins to slowly pull the front and lower the back giving you a long, drawn out squeaky clean. You tear up as your clit gets scraped and squished by the fabric. All of your pussy is on fire and yet you remain wet. The front of your panties are as high as they can go forcing you onto your tip toes to try relieving some pressure. Though terribly painful, you try to hump the fabric searching for some relief in the punishment. Your boss doesn't like this and quickly drags all of the fabric through your lips again.

With the back of your panties in the air again, she resumes the slow drag on the front. Once the front and back are at an equal height, she grips between the leg holes of both sides and lifts you off the ground. Your legs kick and you reach down to your pussy but there is no escape. She starts to bounce you letting all of your weight land on your clit over and over. You're crying as the fabric starts to rip. She continues to bounce you until it gives out dragging through your lips one last time. You fall to the ground and roll onto your back spreading your legs. Your pussy is burning in a way that makes you fear touching it so you raise up to look at the damage instead. Though a deep shade of red, it's still intact. Relieved, you drop your head back to the floor trying to catch your breath.

Bam! Your boss launches a massive kick into your pussy. "Next time wear stronger panties." You roll into the fetal position and hold your battered cunt.
