Ok--you know those little sample-size shampoo bottles? the round ones? I was using one of those, only it wasn't long enough--so I had jammed the metal cap from the top of my lava lamp onto it to make it longer. It worked, stayed on and everything--until after I came. I removed my homemade dildo--and the metal cap stayed stuck! I had to fish it out o' my vagoo, and man did that hurt. Metal edges for the lose.
