Although not an e-stim toy, we bought several of these awhile back and want to get them out of our current inventory.  We are letting them go for almost cost, so get one before they are gone and while you can.

Literally fill and expand your horizons with this inflatable plug.  Use for anal or vaginal enjoyment.  Simply inflate it, lube it, inset it and then pump to your desired size.

Soft, butt (literally) firm silicone material makes it comfortable and erotic when in use.

Insertable to approximately 4 inches.  Diameter when pumped firm for insertion is right at 2 inches.  After inflation, to deflate, just push the button and it deflates immediately.
