LoRa of stained panties. Recommended weight: 1.

Pee stain: stained panties, pee stain

Pussy juice (black stain): stained panties, pussy juice stain

You can include one as negative if you don't want for example pee stain (btw it very likes pee stain).

Black panties are kinda hard (as expected), but not impossible.

Should be compatible with other LoRas that work with panties (for example presenting panties, or panty pull, or smth else)
