I'm a submissive, but I wouldn't play. Not with those rules. I'd want the option to capture and tickle the doms, and even if were against the rules I think I would just do it anyway.
I work in a pretty big office. People are very careful about who they touch. It doesn't help that our HR director is a nazi feminist. She's tried to pressure some of us to register complaints.
I wouldn't get naked for tickling any more than I would get naked for a massage. That's what's so neat about tickling. You don't have to take your clothes off to enjoy it. :happyfloa
