We used to live in a house where across the street were just fields. At the far end of our street was a busy road then more fields with a paved walking path through them. There was a street that somewhat paralleled the path but wasn't too close. The path wandered and there we a couple of covered picnic areas and play areas along its path. My wife Jill and I would often walk down to the path and walk the length of it then come home by a different path. The round trip was about a two mile walk.
A little about myself. I have three piercings down the front of my scrotum that are in what is called a ladder. I have various different jewelry that I wear and trade off. One set I sometimes wear is a barbell that has a loop or stirrup that hangs from it and I'll wear one set in each piercing. One day Jill jokingly said "We should connect a leash to those and I'd take you for a walk." We both laughed.
It was summer so we would go for walks in the late evening after it had cooled off. A few days after our little laugh I suggested that we go for a walk one evening. The sun had just gone down so it was cooler. Jill eagerly agreed. I told her I needed to make a quick bathroom stop and that I'd meet her outside on the porch. When I came out, she turned to walk down the steps but I stopped her and put something in her hand. She looked confused then looked down and saw that she was holding a retractable leash. A look of comprehension crossed her face as she looked over at me and saw the other end of the leash coming out of my open zipper! She smiled and said "Let's go."
We walked down our street across the busy road and onto the walking path with my wife leading the way. As we walked I became more daring. I was going commando and went from just my fly open with the leash coming out to having my cock and balls hanging out with the leash attached. I was wearing tan cargo shorts with a belt. I found that I could undo the button at the top of the shorts and spread them wide open and the belt would keep them up. We stopped walking so that she could check out the leash connection. She fondled my balls and played with the rings. My cock was standing at full attention which she took into her mouth and eagerly sucked. Suddenly she stopped and stood up and said she wanted to keep walking. I pulled her to me and felt in her shorts. She was sopping wet.
We kept walking. Sometimes she would give the leash an extra tug or if I started getting ahead of her or behind her she would lock the leash which would pull me in line. I eventually took my shorts all of the way off and carried them. Occasionally a jogger would come by but it was dark and I would hold the shorts in front of me as they went by.
We finished the first mile and changed over to the other path to head back...
