I was behind this woman going up on the escalator. The deepest, brassiest fart of all time comes out of her ass which was right in front of my face. Before I got too close she turned around and gave me a look. I don't know if she thought I was going in to smell her gas but I got extremely horny by this. Might be because I hadn't blown my load for weeks. Was this a normal thing to get aroused to?
