Nasty SIPs

Let it be noted that the book linked to in the post just prior to this one as some unusual Statistically Improbable Phrases, like "prostate stimulation" and "lick his balls".

Apparently the prostate is a rather excitable little gland. There are no fewer than six references to "prostate stimulation" in that book, and there are five instances of it occurring in Pucker Up: A Hands-On Guide to Ecstatic Sex. Amazon lists 19 other books containing that succinct, but oh so vivid phrase.

"Lick his balls" also appears in How to Have a XXX Sex Life: The Ultimate Vivid Guide, Unlubricated: A Novel, and Corporal in Charge of Taking Care of Captain O'Malley and Other Canonical Stories.
