I am desperate to find a strap-on ejaculating dildo. Not the hand held kind. Any suggestions where to find one?

I've found a few of them, and think this is a good one: the Pumpin' Peter North. It's designed to fit most dildo harnesses, but it doesn't come with a dildo harness. You'd have to buy that separately, and I suggest you go to Babeland, which has a great selection.
