Tickling makes Sol react between agony and despair (FULL VIDEO)

Sol is bound to the bed at her wrists and ankles. She has no way out. After leaving her in the dark for a few minutes we went inside, and as soon as she sees us, Sol knows what to expect!
We start tickling Sol on the soles and legs, and she responds instantly with beautiful body contortions and loud giggles.
I notice that M2 is having a little more fun than usual, so I let him lead the action, I grab one of the cameras and start filming him tickling Sol.
Sol’s reactions get more and more desperate as she realizes that M2 won’t stop tickling her body! M2 is insane! He keeps tickling non-stop, driving Sol to exhaustion!
She screams, tries to bite, squirms, but M2 continues.
