I bought this E-stim butt plug in for an upcoming session, If anyone feels like using one of these in a session, I am happy to buy one in for your exclusive use, they cost £26+£5 delivery.  Electric butt plugs should never be shared as you cannot put a condom on them to keep them clean, and they are not possible to sterilize enough to share, unlike my silicone dildos that can be boiled and cleaned with hospital disinfectant.
