The Ass Spark Invader is a beautifully sculptured design, which penetrates 5” deep. Balls sizes start at .8” and graduate up to the largest ball at 1.5” all in medical grade silicone. The Ass Spark Invader, like all the other Ass Spark designs, can be used alone, but will also be incorporated into up-coming designs. For all you boys that have suits using the metal Ass Spark, this new silicone design will work with them, but it is a tight fit. The feel of the medical grade silicone pushed deep inside along with the 1.5” cock ring, which can be used by all size men because of the stretch; even guys that need a 2.5” ring in metal is just so much fun to wear. The Ass Spark Invader is an exciting addition to our line of erotic accessories.
