The first but not the last time I dressed in publi

So when I was about 16 to 17 I decided to dress in drag for Halloween. I want very hairy and I didn't have facial hair so I figured all would be ok, plus I liked to dress in private so what was the worst that could happen. So I bought some black thigh highs and some sexy and cute little panties. My older brother's girlfriend decided she wanted to help so she loaned me a all lace unlined black bra, sexy and matched the panties, she let me wear a long but very revealing dress with a long slit up the side. Some black strap heels and a black wig. Once I was all dressed and had her do my make up I was shocked at the results. I want passable by no means but didn't look like a dude in a wig. Only one thing was missing. I didn't have boobs, no breast forms or socks stuffed in the bra. So I thought of the next best thing. I found some tan colored balloons and filled them with water and bam I had jiggly bouncy boobs. The Halloween party started and it was fun to see the reaction of everyone but the panties kept giving me a hard on. So after about an hour of trying to fight this boner away I snuck away and pleasured myself thinking it would stay gone for a while or till the party was over but I was wrong. I ended up saying that I was tired and was going to bed and I'd return everything I borrowed the next day. And long behold my brothers girlfriend said she had something to lend me. So we went up to their room and she gave me a corset with built in garters and told me to have fun and I blushed and she said it was our secret. I to this day haven't felt or came so much in one night. I went to "bed" at 9 and was collapsing from pleasuring myself so much by about 3 a.m. ugh to be able to do that one again would be amazing.
