Gross choice. I guess tickled until I pee, because its a one-off thing, but I'd be incredibly angry at someone. So ideally neither.
Tied up v. pinned down is a tough one too, although much less unpleasant. Tied up frees the ler's hands, but there is something to the ler having to forcefully pin you down with her strength. Well, I don't need to do that one, so cool.
Giving raspberries, or tickling with your tongue?
