So I'm doing this chick doggie style, when all of a sudden I get this godawful stench in my nostrils. It's actually burning my nose like ammonia or something. My eyes are watering and I can feel my nose hairs scorching. We had been doing it in other positions earlier, and I hadn't noticed anything, so I'm not sure if it's just because now I'm basically "staring down the barrel" or if it was just parting the ass cheeks let something out, or maybe she ate two dozen jalapeno poppers earlier and just let fly when I got into position. I don't know.

Anyway, I usually try to make things last, but this time I just start pumping like crazy to get it over with. I'm sure she just thoguht I was really into it becasue I'm going like a jack hammer, and twisting this way and that, and making all these gasping and groaning sounds. But really I'm just trying to get out of the way of the noxious mustard gas fumes wafting up from her ass. For awhile I felt like I was in some kind of survival situation.

So I finally finished and got out of the gas cloud. I never told her that her ass really stunk that day, and we had plenty of good sex before that and after, but man, every time I got behind her after that I had an exit strategy all figured out just in case.
