Hi,sorry for my english accent! I am french speaking from Belgium.
Imagine,
You laying in your bathtub, very comfortable,
a nozzle, or an inflatable nozzle, the dream a silicone doouble balloon
a hose with an Higginson syringue,
a bottle filled with 2 glasses white wine and 2 glasses water,
and an other bottle 2 quarts or more filled with water and baking soda
(good mix equal 9gramms for 1 liter or 0.33oz for 1 quart)
and the vibe an Eroscillator who works with 14volts
Magic Wand works with 110volt [font=arial black] ELECTROCUTION DANGER [/font] in the bath
Start and inflate the bulb(s),let the flow go slowly,
from time to time a good pressure action on the higginson,
just to fill you violently for a small quantity of water, but a good feeling,
a few time too a pump to the inflatable nozzle,
If I don't eard You screaming your pleasure in belgium,
you certainly miss something
Arthur
