I always go for early morning bicycle rides on weekends. I always sweat a lot so I wear as little as possible. Usually it is just a t-shirt, shorts and sandals and literally nothing else. On really hot days it is literally only shorts and sandals with no shirt. On one really hot day I was out at about 5:00am in just shorts and sandals. I took a break at around 5:30am and when I was getting back on my bike I somehow got a part of my shorts hooked on my bike and heard a ripping sound. The seam on my shorts that went up my ass had ripped open halfway up. It was still early with hardly anyone around so I decided to quickly ride home with my ass exposed figuring the odds of being seen by many people was low. I was running red lights to get home quickly and everything was fine until I had to stop at a red light because a couple of cars were coming. Waiting for the cars to go by I had both feet on the ground with the bike frame between my legs. Once the cars passed I went to get back on my seat and heard a big ripping sound. I looked down to see the seam on the front of my shorts had split open almost up to the waistband and my cock and balls were exposed. The split up the front was worse than the split up the back so I decided to turn my shorts around with backside being in front now. I literally removed my shorts and was briefly standing naked on the street while doing so. I quickly threw my leg back over my bike to get back on it and when I went to sit down I heard another ripping sound and the seam was now split right from front to back. My ass was exposed along with my cock and balls and I didn't have much I could do but make my way home that way. I only saw one other car who appears to have seen me because they slowed down and were looking my way. I get to my home and swing my leg over my bike and the shorts got caught again. This time my shorts got caught again and it ripped the waistband causing the shorts to fall right off me. It was a short run to my front door but embarrassing as my neighbor, his wife and another woman with them saw me do the short run in all my glory. My neighbor started yelling to ask what the hell I was doing naked and started to come towards me. I stood there telling him the whole story and the two women approached as well. I was using the shorts to cover myself when his wife grabbed them to see them to see if they could be fixed. I didn't expect that and was literally frozen and fully exposed to them. She said the shorts looked too worn to fix. The other woman wasn't saying anything but just looking. My neighbor said it has been an embarrassing morning for me. His wife suggested I better go get myself covered up unless I want to draw more attention to myself to people passing by. Now there was a woman across the street jogging who had stopped to look my way along with another older couple who had also stopped and were looking my way. I went into my house and finally was out of site. I tried to avoid my neighbors because it was embarrassing to have them see me naked but figured it happened and there was nothing I could do about it. They seemed to be cool about everything and told me my nudity didn't offend them. They even went as far to say if I wanted to tan naked in my yard they wouldn't mind.
