My wife came back into town and I showed her all my new toys. She liked using the egg on me, but then came up with the idea to put my scrotum stretching ring on (keeps the testicles from tightening against your body) and stretched the egg over my testicles. She then rotated the egg back and forth while she went down on me...it was out of this world! As a masturbator, the eggs are ok...but used like this...amazing.
