Inspired by some clips on the internet - I wanted to try it too. So I went shopping and got condoms. The consideration - how to inflate the rubber - when it was pulled over the penis - was not easy. I still had an old curtain rod and was able to inflate the condom. Now I had a balloon on my tail and could play and fuck the rubber. A cool new feeling until the sperm lands in the round balloon. Let's see what else I can think of.
