Piss floods her bulging diaper as this heavy BBW MILF hunches low in the steamy bathroom, thighs straining apart over the mat, wet trickle echoing off tiles with every tense squeeze — squelching fabric clings tight, piss seeping down thick legs in rhythmic drips, her heavy breaths turning to gasps while she grinds hips for release. Diaper overflows. Pure filth.
