When I was about 9, I went to spend a few days with an aunt and uncle, to celebrate my aunt's 30th birthday. My uncle had decorated the party room with 6 bunches of tightly inflated balloons which worried my in case they burst. Anyway, none did burst during the party and the next day my uncle removed them and left them in the main living room.
That evening my aunt was sitting in the room watching television when my uncle entered, sat down and said that it was time he got rid of the balloons. He told me to bring them all to him and said I could take one bunch of balloons to my bedroom to play with if I wanted, the rest he was going to burst. When I returned to the room he had one of the balloon bunches gripped between his thighs and he asked my aunt to remove one of her stiletto shoes and give it to him. He too the stiletto shoe and started to slowly push the sharp stiletto heal into each poor balloon. I was terrified and also really excited watching his sadistic pleasure in dealing with those balloons. My aunt ignored the continual BANGS and he just systematically worked through the 30 or so tightly inflated balloons, using her shoe to bust them.
That night I discovered my fetish for Balloons and took the bunch he let me keep to bed to cuddle and rub against. A few days later, when I was leaving my aunt told me to either go up to my little bedroom and pop the balloons or bring them down for my uncle to pop. I did the latter and when he came into the room from the garden he looked at the balloons, smiled and asked me if I had had fun playing with them - I think he knew how I had been using them! Then he placed them onto his armchair and I had to watch him s-l-o-w-l-y sitting on them to burst them. I can remember that one yellow one was trying to escape from him, so when all of its friends had been burst, uncle placed it between his thighs and cruelly teased it with his fingers until it bust. I was mezmorised at how he teased that last poor balloon and although I felt so sad that it was the last survivor, I also enjoyed watching how he was abusing it. My BALLOON FETISH was now established.
