Help my boyfriend is going to tickle torture me!!!?

He announced he will tie me to the bed spread-eagle with my bikini on in bare-feet and tickle me to my limit. I don't know what my limit is and I'm totally 100% ticklish! He said he'd use all the tickling tools he can (e.g. pens, feathers, hairbrush). He said he would stop momentarily for water and breathing but other than that it's ALL SYSTEMS GO.
