Traite ma bite dans une machine à masturbation (c description)

Now I have improved my masturbation machine with a new bottle and a piece of a tube from a moped. I could lie to you and claim that this bottle is the same as in video no.1 but it is not, it's a smaller bottle :) By making a hole in the bottle, the bottle became the flexible part, instead of the point where the screw cap is attached. Good decision.
