I am 22 year old female and this hapepened about 2 years ago. I was on my way to work and I stopped to get a coffee. I knew it would be really hot so I got a bottle of water to go with it. The drive to work is about 45 minutes. About 15 after leaving the coffee shop I began to feel I needed to pee. I was distracted for a second, took the wrong exit and now I had no idea where I was so I just kept driving to see if I saw any streets I knew. I drove for about 35 minutes until I needed gas. When at the station I asked if they had a bathroom I could use but they said they were out of order so I knew I would have to wait, but since I was getting thursty I bought 2 bottles of water to go. I drove around lost and drinking my water but then about an hour later I got caught in a traffic jam and by then I was in a major desperate need to pee. Soon I was bent over with my hand in my crotch trying to hold it in. As traffic slowly moved my wheels rolled over some large construction bumbs in the road and I felt a little bit of pee start to come out. Plan B; I hurried and unzipped my jeans and grabed my pee hole before any more could come out. My bladder was So FULL it really hurt everywhere down there but I could not pee on my seat. I would NOT pee on my seat. Further up the road I saw construction workers and I knew I had to remove my hand from crotch or they might see, but I was afraid my pee would burst out. I got closer and my desperation was getting worse and then I thought "O come on I'm a big girl I can wait this thing out" so I just let my pee hole go and tried to hold it in like an adult. As I passed the workers a few streams of pee came out but I could not grab it again as yet. More of those bump things were coming up and I didnt know it. Traffic was starting to move faster and when I went over them a huge stream of pee shot out dispite how hard I was trying to squeeze it in. I hurried and pushed my fingers into my pee hole again to get it to stop. It hurt so bad and I was wet and I thought about peeing in one of my water bottles but I couldnt do that and drive at the same time and there was no shoulder to pull over on since they were all blocked off. I had my bags and purse in the passenger seat next to me. It had fallen over and a few things fell out. There were some napkins from lunch the day before so I stuffed them down between my legs to pee into; just a little to releave the preasure. I figured peeing even a little bit would help but it felt so good that I couldn't stop for a good 10 seconds and it soaked through leaving me more desperate then ever. I thought about crossing my legs with my hand up there against my pee hole but I knew I couldnt wait more then a few more seconds now that the dam had broken, so I grabbed an empty water bottle and squeezed the bottle kinda under my pussy. I was so scared because I didnt know if I should let go or not cause the opening was small and I didn't know if it would squirt in it or not, but I just HAD TO PEE so I let go. It was so warm and it felt so good to relax and I wasn't even sure where all the pee was going but I couldn't stop; it just felt too good. Turned out most went in the bottle but some soaked into my panties, jeans, and even the seat. O well, lest it wasn't number 2.
