Soaking Through Cotton Panties into the Sheets

There's something about the weight of wet cotton against your skin that hits different when you're lying down. She settles into bed and just releases, a long stream soaking into her panties while she's still wearing them. The pee doesn't stop at the fabric. It keeps going, spreading through the crotch and down into the sheets underneath her body. By the time she shifts, there's a dark wet patch spreading across the mattress. The whole thing plays out in real time, cotton getting heavier, sheets getting darker, that moment where you stop caring about the mess and just feel the relief.
