In this clip, Tonya and Katrina tickle completely defenseless Alevtina. Her friends tied the poor ticklee to a bed by the arms and legs. One tickler girl tickles her upper body, the second one torments her bare feet. Tonya and Katrina change places during the clip.

It's hard to say who is the best tickler because Alevtina doesn't need much, she's extremely ticklish. Alevtina has a very sensitive body and can literally explode from the slightest touch. This feature only provokes her ticklers to tickle her more and more...
Enjoy!
