Nicky is firmly tied and suspended in the air by straps. His body can move but it is difficult. I tied his hands behind his back and ordered him to try to escape from captivity. Meanwhile - while Nicky tries to untie the rope, I play with his nipples - very biting clothespins. Nicky finds it very difficult to concentrate. He has to do his best to untie the rope on his hands, but his nipples prevent him from focusing on it.
