I was bored, so I through a few handfuls of ice into my diaper. I could only take it for about 5 minutes before I had to change my diaper. By then, my little peepee shrunk down to being just a clit. It was so sore that I couldn’t play with it or get hard. I put a double diaper on, and it stayed cold for quite a while! I just wish I could make it permanently this small and useless!
