I didn't expect it but I had my first experience in the mud.
I was on vacation at a lake and went across the lake with a SUP. The bathing lake was not exactly large, but had many inlets. I went into one of them and at the end of the bay the shore started to turn into mud.
I did not expect to find such a place and I was all alone.
I approached the mud with the SUP and tested how deep it was with the paddle from the SUP.
When I realized that the mud is quite deep I decided to slide slowly from the SUP into the mud.
I slid into the black mass and sank into it up to my chest.
And it felt just like I always imagined it would.
I noticed that the mud mixed with sand just below the surface.
The sand mud mix was very loose and I could move in it. And this mass moving around me felt so good. I felt the mud slowly fill my trunks and envelop me like a soft hug.
I grabbed my penis and jerked off. The mud moved with me as I did this and it was as if the mud itself was having sex with me.
When I was done, I could just pull myself back onto the board. I was completely covered up to the neck with this mud.
I went out on the lake for a bit and washed.
I'm really glad I did it and will definitely do it again.
Hopefully in the mud hole on my pictures.
