I posted a thread on pussy suction/pumping in the Knowledge base and wingsofanangel, I believe, recommended trying the suction devices in a snake bite kit. They sell them at Wal-mart and are about $2.00 (Camping Section). I haven't purchased them yet, but you might check out that thread, or ask wingsofanangel.

As for whipping/spanking, the little twisty thing on the window blinds that make your blinds open or shut makes a good cheap cane, and there's always hairbrushes and wooden spoons.

I believe somewhere on this forum there is another list of household "pervertible" items.
