Master Series Flexible Silicone Urethral Sound Trainer Set

 If you are tired of the same old sexual activities in the bedroom it is time to step up your kink!  When you are ready for extreme pleasure then look no further than Urethral Sounding!  Slide one of these silicone sounds into your penis tip hole to find out what unadulterated pleasure truly is.  The Master Series Invasion Urethral Sound kit is made of 4 pure silicone sounds finished off in a masculine blue color.




  • Set of 3 blue silicone urethral sounds for penile stimulation
  • Each sound has a small end and a large end to give you 6 diameters for stretching
  • Designed to provide intense levels of pleasure
  • The perfect set for introduction into sounding
  • The medical-grade silicone is soft and smooth to the touch for easy entry
  • Each rod is extremely flexible to allow your body to adapt 
  • Designed for maximum comfort during use
  • BDSM and kink toys will take your sexuality to a level never known before


Made of premium, phthalate-free and non-porous silicone, these urethral sounds are easy to sterilize and body safe for an all-new sounding experience. These flexible rods bend with the body, sliding down your shaft for that unique sensation that you crave.

Each sound is double-sided, with a different-sized girth on each end. The graduated sizes allow you to work your way up until your stretched-out penis hole can accommodate the largest rod!

Always sanitize and clean before and after every use. We recommend a good sex toy cleaner to get the job done.

Measurements: Each sound is 8 inches in length. The smallest has a diameter of .19 inches on one side and .23 on the other. The medium is .27 inches and .32 inches in width. The large is .34 inches and .38 inches in width.
