On my knees, I slide a vibrator between the string, ride on it and push it to me all the way into the butt-cunt ... Here I jerk off the piston - the vibrator remains stuck deep in my anus! Then I lie down on my back and pull out the string and jerk off on the back with the vibrator in the butt ..... On the knees I cum in the end in front of the camera, while still have the vibrator in it and then inject violently on the string from .... The insulting string I hold the conclusion in the camera!
