In part 2, Cyn is bound to the table and her upperbody is tickled, and she fights every step of the way not to react, but I slowly break her resolve and in no time she is giggling and struggling to break free. Cyns underarms are definitely her weakest spot, and every time I tickle her there, she cant help but break into a big smile and laugh out loud! Cyns hips and inner thighs are also tickled, and those two spots are quickly added to the list of Cyns ticklish spots.
