As a kid I always liked to play in the mud. As a teenager we had mini bikes. And I noticed how when I tried to get the mini bike through deep mud the sinking feeling made me horny and hard.

Then in high school I took a summer class in marine biology. Each week we would go on a field trip to places like the ocean, bays, and harbors for field studies.

This one trip was to a large, many square mile, back bay at low tide early in the morning that left the entire basin drained and exposed an expanse of mud flats. They took us there on a bus and we were told to wear old tennis shoes, jeans and t shirts. We were divided in to groups of 4 and we all started off in different directions with our note pads and collection bottles for the studies.

My group had my good friend and there were two girls from the class. Everything was going along fine and we were wading in shallow mud along the edge of the flat trying to be good students. Then one of the gals spotted a raised grassy island in the sea of mud a short ways out on the flat. So we started in that direction.

It was slow going sloshing through the mud in tennis shoes and jeans as the mud would cake to our pants legs. We were about calf deep and soon in over our knees. We had to cross a very slight depression and then we would be on the island. As we started to cross the depression the mud suddenly became very light and creamy but also deeper. Just about to the island the gals where about up to their crotch and started to sink in a little deeper. One of them kind of panicked. Guess she thought she was going to sink out of sight, lol. So since I was taller I waded over to her to pull her through and on to the island.

OK, so here is the four of us crotch deep and deeper in this wonderful light creamy mud. The sight of seeing the two gals in the deep mud started to arouse me. And as I worked my way through the mud to get to the girl, all the leg and foot action started to make me hard. When I got to the girl to help her I was rock hard in my mud clad jeans. I could have exploded right there!

We made it on to the island and she was fine. So fine that on the way back she saw how she could control her depth and started to really get in to it. The two girls went on ahead and when they got back to the deeper depression they both started to really get in to it and actually twisted their waists down in to the mud a ways just to play.

That was it! I was hooked. And from there I started to go out alone looking for all kinds of mud spots to sink and play in.
