za Thickcock278_ :First, I measured my penis circumference, then bought a slightly larger transparent cylinder online with a cap. I glued it together with hot glue. I made a hole in the middle from a bicycle valve, and that was it :)
za SpycamMilking :I have a Tremblr also. This is a great idea. I'm always going through silicon sleeves. They aren't too expensive but it's just waiting a long time to get them. Plus I've never been impressed with their customer service. Where did you get the cylinder?
