It does add to the experience, as verbal communicating between lee and ler makes the experience fun. After all, most tickling is about communication, right? As what sole seeker said, it can add a certain element of "fear" and intimidation. When the ler is approaching you with wiggling fingers, uttering "tickle, tickle!", of course you get into a sweat! As for lees saying they'll get you back, etc. it's kinda sweet, as they can talk the talk, but can't do fook all about it being tied and tickled and going nowhere! All these elements would probably make a truly enjoyable tickle session!
