Ah, one of the nice CB models. I do like these, I have several of my slaves locked in these already, and my personal Bull locked in a georgeos metal variant. They are so delicious aren't they.
Well, before putting it on, I think it's time for a bit of stroking first. No point locking it on without getting you worked up over it first.
Grab your cock, firmly, and use your index finger to really rub the area under the helmet. That delicious area that sends tingles all down your shaft. I do love licking and biting right there, the faces my slaves make when I bring them to the edge of orgasm and bite down right there... Hmmm, making me wet just thinking about it...
Are you nice and hard now? Good... give yourself thirty quick strokes, make them fast and hard, really wank that dirty cock for me... Once you've done that, you may continue...
