Octopus - The Sister - Don't Laugh Challenge - Feet Up

Ielena challenged Octopus. After the last video Ielena said that if she concentrates, can resist, so she will have to take the challenge: don't laugh challenge! If she can not laugh for more than 30 seconds, she is released immediately, but if she laughs for her it will be worse and worse. In this challenge the torture grows progressively, to the point where sister Kelevra begins to watch Ielena with concern: she has never laughed so much in her life!
