Well, Rob, seeing as how you're partial to foot tickling like me, I don't think you can go wrong with any of the issues, as most of the tickling is done on the feet. I have all three, so I should know! 😀
I guess since this is your first issue, you should get just that, issue #1--it's a nice intro to VU and will help you understand the story better. The artwork is awesome, and so is the plot! It's mostly f/f foot tickling, with a little f/f upper body/underarm thrown in (no men appear). All the women are, of course, beautiful, as are their feet! I'll stop raving about VU now so you can order it. 😛
