I squeezed into my little girl size Hello Kitty panties then I filled them, wet them and masturbated myself!
I just got some new Hello Kitty panties and I deliberately bought them too small so they'd be super tight and snug on me. I like the feeling of the panties pushing back and resisting when I do a poop in them. It's nice to have the poop held nice and firmly against my butt while I masturbate. I started feeling horny as soon as I put them on, as I knew what I planned to do in them.
So I pushed out a load of poop into the panties, and as expected, the bulge was held nice and firm against my butt. It was a perfectly rounded mound of poop, and if I'd been out and about it probably would have stayed hidden safely under my skirt. But I had no intention of hiding it - I wanted you to see it in all it's glory.
As I was masturbating I started wetting myself, and the pee mixed with the mess to make a big dirty stain!
The with poopy bulge now wet and highlighted by my pee, I continued to move about and change position, showing off the messy wet bulge, all the while never stopping playing with myself. I rubbed myself through the panties and with my hand inside too, directly on my pussy. And the more I did it the closer I got. A naughty wet and dirty little girl in her Hello Kitty panties was about to cum - big time!
After I was done I knealt on the leather sofa, and pulled my panties down to show you my dirty butt. To my surprise I did another little poop that landed on the sofa. The panties had put up more resistance than I realized. But that was ok - that was the plan all along. I pulled my tight little panties back up to show off the horny dirty wet bulge, with the new lump of poop sitting underneath on the sofa!
