Ok, I just heard it, and I just attached pics.
We're going to have to wait for the video clip to get the full impact. They ordered the girl to tickle Valentina but she did a lousy job, so Gary took over...but he was holding the microphone in one hand and tickling with the other. So the sound is obscured, though what laughter you do hear sounds authentic and sexy. Best part for me was the lead up when she obviously didn't want to get into the tickle chair and be tickled. I'll upload the audio clip somewhere so you can hear it but that's the preliminary verdict. Here's pics attached of the girl tickling her.
