Walking a dog while riding my own log

Really had quite the experience the other day and I'm still reeling from it. I've been dog sitting for a few days at my house. It was pretty hot for a few days and I spent most of the day working from home in my underwear cause it was too warm for clothes. I ate dinner and fed the dog. As the temperature started dropping and it got later and later I decided to take the pup on a really long walk. I did what any sane girl would doo, I put on a cute summer dress that's pretty fitted on top that comes about 3/4 down my thighs and a similar length rain coat because it was forecast to rain tonight. I took a quick pee before leashing up the dog and heading out (wouldn't want any accidents would I?😆) Puppy by my side I headed out of the building and down the sidewalk. After about a km or 2, I felt a familiar pressure at my rear gate. A familiar pressure I know well. I felt a firm log knocking. I kept walking for a little while feeling my urgency grow. I didn't have any change on me so the public toilets we're out of the question. As time went on my urgency continued to grow, now 3 or more km from home on busy city streets. I realized I had the perfect wingman locked in on a leash. So looked for an opportunity. I passed a busy restaurant with an outdoor seating area. They had a menu on a chalkboard on the street outside I too a slightly wide stance and bent down to pretend to read the menu as I started to push. I was right, it was firm. I kept pushing, seconds felt like minutes but my ass cheeks parted. I took a second to nonchalantly catch my breath and continued to push. Out came one long log and then the next. I finished with one still stuck between my cheeks. All the while people passed me, leaving the restaurant and one even stopped to pet the dog very briefly before moving on. I stood up fully and looked around, the people seated seemed wrapped up in conversations and food not noticing that the brunette checking out the menu just thoroughly and intentionally shit her panties in front of them in full view. My bladder had let a few drops escape but my panties were soaked for a completely different reason. I continued my walk as if nothing had happened. I stopped every little while to adjust things as it got darker further cloaking my dirty deed. The dog stopped a few times to do his business but once or twice seemed more interested in mine. As I walked and the kms went by the firm logs became more and more of a single solid mass. More than once I crouched down and pretended to pet the pupper while feeling my mess in pure ecstasy. People stopped to complement the dog once or twice including a cute girl in her 20s. Had a casual conversation about what type of mix he is meanwhile I couldn't help but cross and uncross my legs and once leaned up against a building to subtly feel my mess more. I even joked to her that I'm more of a shitzu girl personally but you can't argue with that face. I was DRIPPING 💦. Eventually I realized I was getting way too far from home and the dog still hadn't pooped yet. Made it back til a little more than a Km away before the dog finally went. At this point the mess in my panties was one solid mass and getting messier, heavier and colder by the minute. It felt like it was sagging more and although I didn't want it to end I crouched down with a baggy and before picking up the dogs poop, flipped out my panties and picked up both in my little dog bone covered baggy. I tied it off, fixed my panties and finished the walk. I got home gave the dog a chew to keep it busy, ran into my bedroom threw down a towel and grabbed my favorite toy and fucked myself silly until I didn't think I'd be able to walk to the bathroom to clean up. Now I sit here, ass clean, in new panties dog on my lap considering getting a dog of my own.
