When I was a schoolboy, I used to get sexually excited by sitting in warm mud in my backyard (though I didn't know what it was). As I grew, I realized a nice bath in my t-shirt and underwear. As a late bloomer, it wasn't until I was around 14 that I finally discovered the magic of baby oil (still fun today!).
I combined all of those experiences into one, and had at least a full minute of cum drooling from my cock.
