Our vibrating combo cock ring and finger vibe is a great little 2-in-1 sex toy.  Use the larger ring for the shaft of your penis or the smaller ring for your finger.  The cockring has pleasure nubs on it so her clitoris will get the attention it deserves as you thrust in and out.  She will also feel the vibrations from your whole dick, and you will too.   Just slip the bullet vibrator through the 100% silicone tunnel and press the button for thrilling vibrations.  You can use the bullet vibe by itself, too.  It's a great addition to your sex toy collection.  Includes 3 LR44 batteries.
