This is the third scene of Moddermonster in the mud. It's half an hour of mudfun!

He wears tight jeans and a sweater. He's walking down a quarry and suddenly the road is gone. It's all mud! What to do now? The shortest route between two points is a straight line, so. He sinks in the mud up to his knees and finds out that it's very hard to walk through the mud and falls over. This makes him hard! He doesn't reach the other side because he enjoys it so much he starts rolling around in this thick, smooth clay. Eventually the clothes come off because they're too heavy with all the mud. Wearing just his underpants, he continues rolling and crawling in the mud and dunks his head in it. You can see his hard, muddy cock several times. Especially at the end when he jerks off.
