I had enjoyed laxative suppositories for a while when someone on the internet suggested I try Phosphosoda. I bought some and waited for a night when my wife had to work. I put my depends, drank the laxative as instructed, followed by 2 glasses of water. I got on the chat site and waited. About a half hour later I was hearing my tummy rumble but no urges to poop. I got up to go get something to drink and I felt like I had to fart. So I let go. It was not a fart. I instantly filled the diaper. I couldn't stop it at all. I sat back down and soon had a strong urge to poop. The person on the chat who advised me about the laxative told me to try and hold it. I did for about 15 minutes and then had a huge accident in my diaper even though I was sitting down. After another 20 minutes of strong urges I stood up to try and hold it back. I couldn't. I could slow it down but I couldn't stop it. I could feel my body cramp and then a forceful squirt would shoot into my diaper. I went so much that the poop over filled the diaper and covered the chair and made a mess on the floor. It was unbelievable. Other than the first gush, the pooping was mostly like thick water. It did feel great.
I've used this laxative since then, but that first time was awesome. I have never pooped so much in my life.
