For upper body I like the lee on her back, legs spread, wrist cuffed together and -- favorite detail: -- the arms bend at the elbows so the hands are pulled over the edge of the bed and tied at a point below the surface of the bed. Also the head shoul be slightly over the edge so it titls just a bit backwards. The pits are open, the boobs present themselves very well and I love to see her lift her head to see what I wiil do to her hips.
For feet, the L-position, with hands tied behind the back, so she is lying on them. The heplessnes is total, I have eye contact and some lees actualy manage to sit up for a while - not that it does them any good 🙂
Can I pose a related quistion: most people, like myself, use a posistion that is fairly comfortable for the lee. What does people think of more punishing, uncomfortable positions, with strapado, bend over backwards and the like.. Obviously the lee should be in such a position for shorter periods. Personaly I think it might distract from the tickling and also raise the risc level, but it might also be fun.
