Farting in Polka Dot Panties
Stand with your back to the camera, your legs slightly apart, wearing sheer panties with black polka dots stretched tightly over your butt. The fabric is thin, clearly showing how your cheeks clench and separate each time a fart builds up.
The first fart comes out long and heavy, with a deep, wet, drawn-out sound. The panties visibly puff out in the middle, the polka dots stretch and distort, and the sheer fabric presses against your skin as the hot gas pushes its way out. The smell is thick, foul, and heavy, lingering in the air and filling the room immediately.
It starts slowly, then explodes into a deep, continuous, loud sound that lasts for several good seconds. The smell is heavy, nasty, and overpowering, filling the entire space and lingering in the air long after the sound has stopped.
