Ok, well, you all know of the produce bags in the stores? Well, I found out that they make a great substitute condom if you like to 'hump' your bed or sleeping bag. They literally stick to your penis. It feels like there is nothing there and it catches all the cum! And they are free! Just go to the store and take a couple off the thing. But if you try this I suggest that you cut the bags in half and tie a knot at the end. Then you can use it twice and it will fit better because those things are a foot or over a foot long. Happy jacking.
