Double the anal balls for double the fun and excitement. This Ass Spark Double Bump is not for the inexperienced. If you are new to anal stimulation, then you will be best to start off with the standard Ass Spark. On the other hand, if you are ready to graduate to something more extreme, or you just want to add an additional Ass Spark design for those times when only the most extreme will do, then this is the design you have been waiting for. The Ass Spark Double Bump has two full sized metal balls and goes an additional 2 inches deeper. This design is available with a 1.5", 1.75" or 2.00" cock ring.
