SnapshotAt a garage sale I bought an automatic breast pump, for a specific purpose in the shop. Unfortunately it was not powerful enough for the application.
Then one day will using my penis pump, a light went on. :) I thought why don't I take some plastic tubing and hook it up to the breast pump. After a bit of making a few adjustments I was in heaven.
When the opportunity presents its self, I pop a porn disc in the DVR, lay back and turn on my pump. It takes considerably longer that simply masturbating, but when you get off the orgasm is awesomely intense.
Try it, you will love it.:)
