Every now and then the urge hits me to soil my underpants. Sometimes I follow through.

Today I let the need to pee build to a nearly excruciatingly urgent point. By this time it felt like I could probably have a bowel movement as well.

Once in the bathroom I did not pull my pants down. As I stood in the bathtub fully clothed (except for shoes) I let go! Pee immediately streamed from my cock and soaked the front of my pants, then ran down my legs, soaking my pant legs and my socks. By relaxing my sphincter a turd squeezed through my ass-hole and into my briefs. It felt warm and soft nestled against my perineum and ass cheeks. The erotic naughtiness of it was thrilling!

When I was done peeing and it did not seem another turd was imminent, I slowly bent my knees and squatted down, relishing the filthy feeling as the shit in my briefs was forced up into my ass crack and squished around wherever it could go. This made my already semi-hard cock become fully erect, pushing at the waistband of my briefs. My cock urged me to masturbate NOW!

But I had other plans for today, so after several minutes of enjoyment of being a naughty boy who shit his pants I cleaned everything up and had a shower. There was someone expecting me to fuck his ass in a couple hours, and I wanted my cum to still be available, ready to be deposited in his ass later!
