I don't know what the url is, but I remember as a wee child exploring the internet before pictures were quick to load, and the text was all we had, finding a story about a wife discovering her husband sexting with another woman. They proceeded to surprise him, and yes, a strap-on was pulled from a bag. The only phrase from the story that I can recall was him describing it as a telephone pole being shoved up his ass.

...I've never been able to find it again. If you find such a thing, don't ever let it escape you.
