Milk Bottle for men
If you do not have the Milk Bottle Adapter yet, you must order it separately so that you can attach it to the shaft.
This device is used to hump the male sex. Insert your penis and you will ejaculate hands free. You will feel like you are being sucked. The diameter should be adjusted to the diameter of your penis. This operation has to be done once. For this, heat the neck of the bottle with a hair dryer and distort the entrance of the bottle into a triangle so that it presses your member slightly. By applying Vaseline on the neck, it will improve the sensations.
