Escape to fart in my room

I have friends over 2 times.The first time I wear my tight jeans and very high heels and the second time my turquoise leggings.Every time I have very very bad gas and need to leave the room to relieve myself.I go in my bedroom and start to let out all the smelly gas.I fart so loud and long.I hope nobody heard it.When my guest leave I close the door and feel relieved and let out one big fart.
