In this video you can see a new challenge for Nat, as Mary proposes to tickle her non-stop on her belly and armpits but with the condition that she must be standing and with her arms raised, if she gets them down she will stop tickling her. Mary uses only her hands making quick movements and pressing Nat's belly, finally she uses oil to make the experience more exciting and hard to contain the laughter.
