Inflatable Cock Ring

Now here is a cock ring whose time has come.  Although the inflatable cock ring is kind of cumbersome with the air pump attached, you get to be in full control.  You just slide the ring over you cock and testicles and pump it up at the right time. The quick release valve lets you release the air at just the right time too.

As always make sure you don't over do it with a cock ring.  A cock ring prevents blood from getting to your penis and should not be worn for extended periods of time.
