how long should i tickle her

where should i tickle her ?(she is more ticklish in feet, should i tickle her there) ?

what is the best tool to tickle (feathers, hair brush, teeth brush, fingers)?

don't tell me to do other punishment, because i already swore that it'll be her punishment and if i don't do it she will keep making fun with me and with other brothers... (she made fun when i told her that i would tickle her, 'cause she thinks that i don't have courage, so, i gotta prove her that i can do it !!!
