hi... hmm, the one with the mechanical brushes sounds familiar, sounds like the sort of thing i might have drawn, a woman trapped in ducts and tickled by the jets of the cleaning system is a recurring fantasy of mine, as are girls dangling from branches while being tickled by something that makes it hard to hang on, and i have drawn a few pictures of both of those happening... it was probably quite a while ago and a few years back i lost all my files and artwork when a hard drive went fizzle... maybe i should do another 'tickled by cleaning water jets' one... thanks for the message, glad you like the drawings
