Dirty Jade - beige panties are perversely soiled with piss and shit

Excited to show you this new set of underwear I've been saving for this special moment, I slip off my jeans and step out of them, revealing the beige panties that hug my curves snugly. They're not fancy or lacy, just simple cotton panties I know you'll love seeing get all dirty and nasty. I sit down on the floor, pulling up my bare legs to give you a better view of my underwear. I lean over slightly, letting my breath catch in anticipation as I imagine what's about to happen next. I feel my bladder start to burn, but I resist the urge to stand up and relieve myself just yet. Instead, I wait for the right moment, savoring the building tension inside me. As I sit there, slowly squirming in my chair, I can feel the heat from my pussy radiating outwards, spreading the moisture all over my panties and making them stick uncomfortably to my skin. Finally, I can't take it anymore. Without warning, I stand up and quickly undo my fly, allowing the warm, thick liquid to gush forth and soak through the fabric of my panties. I can't help but gasp as the sensation overwhelms me, and before I know it, my panties are completely soaked with my urine. But it's not enough. I need more. I need to push myself further than before. So I kneel down, hands pressed tightly against my thighs, and grind against my panties, forcing more and more of my warm, wet pussy juice between my skin and the cotton barrier. As I push myself harder, the fabric begins to give way, stretching and straining under the assault of my eager folds. Then, finally, there's a tear - a long, sloppy gash that runs right down the center of my panties. My heart leaps with excitement as I see the dark stain spreading outward from the tear, slowly merging with the already soaked patch in front. And still, I don't stop. My body trembles with excitement as I feel myself on the edge of losing control. Slowly, deliberately, I lower myself back down onto the floor and press myself against the now-stained fabric, rubbing and rubbing until my fingers are coated with the sticky mixture of urine and pussy juice. It's time to finish what I started. With one final, powerful thrust, I push my fingers deep inside myself, feeling the heat and wetness surround them completely. And then, with a long, moaning sigh, I let go, emptying my bowels and filling the crotch of my destroyed panties with a hot, steaming mess of shit. As my face flushes with shame and my body quivers with pleasure, I glance up to see if you're still watching. A smirk tugs at the corners of my mouth as I see you, fingers already stained with my filth, jetting your own load onto the screen in excitement. "Told you you'd like this," I breath out between gasps, leaning back against the wall and admiring my soiled creation. "And don't worry, I've got plenty more where that came from."
