you know when you blow up a balloon and then pull the neck out so the air escapes with a long squealing shriek? Some people can do this with their butt!!
Large amount of gas that extracted out of a woman with a big round ass After she just received a long fuck from a 12 inch or larger dick. This results from the holding in the gas for a long period so she doesn't fart on the guys dick while getting it up the ass....Often happens in the hood among black or spanish people
