Fun topic!
Most daring thing I've done:
At some point I wanted to have al little bit more excitement in my wearing a diaper. I had never worn a diaper somewehere public where I knew people, but I did went out sometimes diapered and just going through a mall or something.
When I read somewhere about the marshmallow trick, that seemed a good way to spice it up.
So I bought some marshmallows, put in four or five, and diapered up. At first I needed to go really bad, but then the feeling went away. I figured this might be a bit too easy, but I wanted the insecurity of whether I could hold it or not.
Figuring I could, I went out. It was a warm day, and I decided to go to a mall about 15 minutes driving away. If I couldn't hold it, I would have the extra punishment of having to sit in it on the way back.
I did bring my coat, even though it was hot. But I tied it around my waist, so it hung over my backside, lowering the chances of anyone noticing the bulge that might be appearing back there.
Anyway, I got to the mall, still not feeling much, and I was preparing for an uneventful trip. Also because it was evening, and there were not an awful lot of people out there. But once I was a bit away from the car, cramps did start to hit me. I had set out one goal, getting some money from the ATM. When I got there, one person was in front of me. I was pretty desperate by now. But I wanted to hold out. When it was my turn, I took three steps to the ATM, then punched in what I needed, and at that point, the inevitable happened. It felt like a huge mess, and it felt good to be rid of it!
So I finished at the ATM, then turned to walk away, and only then did I notice an elderly couple behind me, waiting for the ATM. I don't think they noticed anything, but it was a testament of how preoccupied I was that I never noticed them.
So I walked away, taking a different route back to the car as I took at first. Suddenly and quite unexpectedly, the clouds burst, at it began pouring rain!
I took shelter under a sunroof of a store, where a second load worked it's way into my diaper. It felt hot, and huge, and I was thankful for the coat, hiding the bulge. However, the rain didn't appear to be blowing over yet,'and more people joined me under the sunroof. I was worried they would start to smell something soon!
I decided to face the rain, and walked away to my car in the pouring rain.
To this day, I still have no idea what people thought of me. Did they even notice me? And if they did, did it occur to them it was rather strange, seeing a guy marching soaked through the rain, with a perfectly good coat tied around his waist?....
Even if they did, I doubt they'd have guessed why I didn't just put the coat on. ;-)
