I just thought I would post my experience with one of these toys.  Some of you may have seen my posted video of me playing with it and all I can say is , "Wow".   I ordered it from a Toronto online sex shop and got it in about 2 days in an unmarked box, very discrete.  It really does feel like the "real thing", especially when you pop it into some hot water before using to bring it up to body temperature.  The cost is around 75 bucks and comes in different formats, ie mouth, anal or pussy and some have ribs and some not. It is not a vibrator, but you can adjust the suction strength of it by restricting the air flow. It goes easily from tight to wet and sloppy with the turn of the top. You can pnly use a waterbased lubricant as the others will damage the material.  There are whole websites and forums on how to use it and modifications you can make to the design, but I will leave that to the engineers out there. I am happy with the way it works now. So ladies, if you are looking for a toy to occupy some of hubby's desire, this is certainly the route to take and guys if you want a realistic fuck whenever you want, try this, as I said it works for me.
