If you think that was fun you should look into figging.
"A peeled ginger root, shaped like a slender butt plug, inserted into the anus without lubrication of any kind. The ginger juices cause pain and extreme horniness. The person belonging to said anus become twitchy, jumpy and very lively. The effect lasts for about 20 minutes or more depending on the freshness and strength of the root. The root can also be applied directly to the clitoris or inserted into the urethra."
"The word comes from the 18th century. Unscrupulous horse dealers would insert a peeled ginger root into the anus of a slow or half dead horse. The horse would become lively and hold its tail better. The spelling was feague, but over time became figging."
