Who does the tickling?
It varies, but whenever possible I try to have the models tickle each other, so most of the action is F/F. I do help out the ticklers from time to time, and in a few cases I don’t have a choice but to be the main tickler, like when a model poses solo. Whenever I need to appear in a video, I do my best to be discreet about it, mostly only showing my arms and hands.
