I was over at my sister in law's place with my wife and we were watching a movie. I had to go pee during the movie but figured I would try to hold it until after the movie had finished. The movie finished and my wife got into the bathroom beforee I had a chance to. My bladder was about to busrt so I quickly ran out back to pee. My sister in law saw me rush out and followed me as it was unnatural for me to act this way. She asked if I was alright and as I struggled to unzip my pants and pull out my penis to pee I told her I had to go really bad and couldn't hold it any longer. It was too late and I literally began to pee in my pants. I couldn't stop the flow so by the time I managed to pull my penis out of my pants my clothes were pee soaked. My sister in law saw the whole predicament as the stream of pee flowed out of my penis and hit me almost everywhere when I was pullig it out. My underwear, my pants, my socks and even my shirt was wet with pee. I wasn't wearing shoes so at least they were spared. My wife came out back to find me standing in front of her sister with my penis in my hand, still peeing, and didn't seem very happy about her sister watching what I was doing, particulary seeing what I was holding in my hand. When my wife found out the whole story she was very understanding. My wife waited until I finished peeing before she told me to take off all my wet clothes. I was reluctant since we were outside and could easily be seen by neighbors but knew I didn't have much choice so I stripped naked. I was standing fully naked in front of my wife and her sister in the backyard where any neighbor could see all of me if they looked out their windows. My sister in law grabbed my clothes and brought them in to get washed. I was covered in pee and knew I had to take a shower to get rid of it but didn't think my sister in law would appreciate me walking into her house the way I was. I noticed a garden hose and decided I could rinse off myself before I went in and took a more thorough shower. It was around 7:00pm and I was standing naked in the middle of the backyard rinsing myself off using the garden hose trying to get as much of my pee off of me that I could. I guess the sound of the water running and my wife, sister in law and me talking atracted some attention. There were a few neighbors looking out thier windows at me as I rinsing myself off naked. I finally went in to have a real, more private, shower using soap. When I was done showering it became apparent that I wouldn't have anything to wear until my clothes were done washing and drying. It is about an hour and a half drive home and my wife had to get up early so she was thinking that either I stay overnight or I just borrow a towel to get me home and pick up my clothes later. We decided to borrow a towel which I wrapped about my midsection to keep myself somewhat decent. Since I wasn't wearing my shoes when I pee on myself I was able to wear them home. My wife drove us home and was in a playful mood. She had pulled my towel open a few times right when we were driving past buses giving some passengers a look at me. She really got me and had some fun with me when I fell asleep and she managed to remove the towel from me completely. I woke up naked wearing only my shoes in the car which was parked on the street in front of our house. The reason I woke up was that my wife left her cell phone in the car and called to say I better get in the house. I told her to get me some clothes but she told me I was going to have to run naked from the car to the house. After some back and forth arguing I realized she was serious about having me run from the car to the house naked especially when she briefly set off the car alarm with her remote. The car alarm drew some attention and after she turned it off she told me I had 10 minutes to get inside. I waited 5 minutes and then left the car, locking the door behind me. As I entered my house my wife was there waiting and laughing as was our next door neighbor. She handed me a towel which I quickly wrapped around me. The 2 of them were making comments and joking about my predicament so eventually I decided to play along which ended in me removing my towel and being naked with them. The neighbor seemed to be liking it a little too much and my wife seemed to be getting angry with me showing myself this much to her and was trying to get me dressed and covered up. I stayed naked and my wife finally told the neighbor she had to go because we had to get to sleep. Once she left my wife gave me a few words about staying naked in front of the neighbor and I told her if she didn't want me naked in front of people she shouldn't have stolen my towel and left me in the car. She said she wouldn't do it again but told me something I didn't even realize occurred. I was sporting an erection during some of the time when I was in front of the neighbor. I told her I didn't even realize I had one which now made me very embarrassed having the neighbor seen me in that state. Since then neighbor makes the occassional comment about me and that day.
