This is for all you "panty boys" and you fans of panty rides and pantied-ass face sitting.  I'm going to smother your face wearing a pair of silky, shiny, full-cut panties on my big round ass.  I plop my butt onto a squashy little pillow and grind my ass into the pillow, rocking back and forth and bouncing up and down on it.  Just imagine the pillow is your face and I'm smothering you as you lay helpless, scarcely able to breathe beneath the weight of my mighty, panty-covered butt cheeks, and beneath my bare cheeks when I pull my briefs up into my long deep ass crack.  I command you to tongue my pussy and ass as I grind the nylon gusset on your face, and you won't be able to come up for air until I say so.  Think you could take it?
