When I was about 25, I worked the overnight shift and made friends with a guy who worked at a grocery store during the same hours that I worked. We both got off from work at 6AM and often would get together afterward and have dinner or often have a few beers.
Once, he invited me to do this just before getting off work. I’d already been planning on leaving work and spending the morning relaxing in my diapers and had actually put on disposables in the bathroom at work--two toddler sized Pampers (the kind in the purple boxes) that I'd overlapped so that they fit me properly and could hold more pee.
When he invited me over, I started to decline but thought “oh why not, I won’t be there long.”
So when work was over, I headed over to his apartment with diapers under my pants. Upon getting there we started drinking beer then he decided that he needed to meet a friend and pick up a package. I went with him, not thinking it would be very far away. Well, his friend lived up in the mountains somewhere, and it took an hour to get there and an hour to get back.
Meanwhile I needed to pee, often, and was drunk enough that I didn’t care and just peed in my diapers the entire time. By the time we returned, my diapers were soaked to the max and then some. My pants were also completely soaked. I told him I had to leave, hopped out of his truck and saw a HUGE wet spot in my seat. At the time he didn’t say a thing but he never invited me over anymore. Oops.
