There's no initial shock! Not really. Perhaps there is a better word. Anyway...all the women I've ever pied - who are being pied for the 1st time, that is - know what's about to happen. I would never pie a woman by surprise! Who knows what would happen!?! I always ask first. And if it sounds like fun to the girl, then I'll arrange to pie her. Usually - right after their 1st pieing - they'll laugh hysterically, & get very, very, very frisky. Did I ever tell ya story of when I pied Sally Field? I pied all the young starlets back in the day. Hollywood hired me to consult on every movie & TV show @ the time. It was a lot of hard work, but SOMEBODY had ta do it! Going back to the 1960's, I got to teach Annette Funicello, Marlo Thomas, Patty Duke, Elizabeth Montgomery, Elvira, etc, etc, etc. All of those women - & more - learned how to get pied by Me! No Brags, Just Fact...
Well , your odds are better if it's your girl friend or wife/partner...and you're both in a playful mood (sheesh guys, some spontaneity, please?)...I pied my ex-gf by surprise (while on camera and rehearsing for a video play we were doing)...she was stunned, then "pissed" (but trying hard to keep from laughing at the same time) ...as I handed her a pie to pie me with...and she clobbered me with it....and, both still laughing, I pulled her towards me and we had what was perhaps the most erotic kiss of my life, so far...sorry, TMI
The first one was during a food fight WAM session early on in our relationship (custard and cream flan). Dubberdee breathed in just when the pie hit. Although laughing uncontrollably she didn't find pies in the face very enjoyable at all as this ALWAYS seemed to happen - often causing days of minor nasal discomfort. When we started filming we had to try to work out a way of avoiding this happening.
Fortunately, after a bit of practise we've got it down. In fact, these days, it's second nature. The idea of 'pie training' is not so absurd after all.
BTW she certainly takes no prisoners when pieing back!
This is not exactly what you asked about, but it's at least tangentially related...
Many years ago, I chatted a number times with a woman online. Over the course of our conversations, I described my pie fetish to her, and she was intrigued by this, saying it sounded like a lot of fun. Later, she told me that she actually tried it out on her boyfriend, giving him a total suprise pie to the face just as he stepped out of the shower. She said that at first he was angry, but then when he realized that she was doing this as a form of slapstick foreplay and he was about to get laid, he suddenly became fine with it.
Love you, too
