As I walked down the sidewalk alone, cars whizzed by, the people inside paying no attention to what I was doing or what I was wearing. My nipples poked into the the white top I was wearing - if anyone happened to walk past me, it would be very easy to notice. Knowing that only made me even more horny and my pussy to be even more wet, spilling it's juices into the child-sized pull up diaper I was wearing under my short-shorts. I had begun my walk to the park about 15 minutes ago, and for that long I have been probably the horniest in my life.
Today was a great day for the indulgence I have been planning for weeks now; it was hot, causing me to sweat quite a lot, the sky was beautiful, and my parents were out of town - giving me the time I needed.
It only took 5 more minutes to reach my destination. I started on the park track and climbed up the stairs to the right of it to reach the picnic area where I was nearly alone, only a few people where there, which is what I wanted. Being a fan of exhibitionism, I liked the thought that people were going to be around me when I went through with what I was about to do, but entirely exposing myself was not something I wanted to do, luckily there was a bathroom nearby.
For the past 3 days, I haven't shit at all in order to have enough for this occasion. Since I woke up this morning, I haven't went to the bathroom to pee at all, instead drinking enough water to make my bladder full. Holding all of this has been hard, but my desire to go through with this pushed me through. Walking only made me want to let go, but I couldn't yet.
