I'm getting some leather cuffs this week from a sex shop near me. It will be my first set so I'm going with something basic to start. Hopefully I will like it.
As for positions, spread eagle is good but I prefer a Y position. With the arms spread above and the feet tied together. This puts the ticklee in a situation where they can "defend" themselves by putting one ticklish foot to block the other. It's seemingly effective but deviously not!!
Other than that if I'm focusing on feet then I also like them on their stomach, hands tied behind their back, and ankles tied together as well. Not sure the name of that one.
