Ha, the ironic thing is I was trying to avoid another overused term ("sweet spot") when I wrote that line! We need more writer-friendly terms for that part of the body. ("Hot button" most definitely doesn't do).

I envision the piercing as a classic Prince Albert. I actually got the idea from ldybastet's fics - she had it in one chapter of Ruki's Kinky Adventures, and it was too hot not to use! Thanks for reading - I'm glad that you liked the fic even though the pairing usually isn't your thing!
