Back a few years one of my buddys got this male blue heeler, his name was jake, the first time I was over there he came to me, I petted him, then he went off and layed down and just watched me. This is the way it was for almost two months, then  my buddy mowed a few acres of hay, two days later I pulled in with my tractor and rake. Jake came to meet me, then walked away, my buddy was just ready to go bale hay for his neighbor. I pulled into the field, jake followed me, while I raked he chased swallows that were flying around catching bugs. I finished raking by this little stand of trees about an hour later, I got off the tractor to take the rake out of gear, when I turned around jake was standing in front of me. I reached down and petted him, but when I started to walk around him, he put his paw on my knee. I petted him again, but he wouldn't move away, instead he stood up with his front feet on my waist, then his paws went around me and he started trying to hump me. I'd been humped by dogs before and loved it, but I  thought it  was wierd of him, he'd never had anything to do with me, but I thought if you want to hump me I'll let you. He got off and we walked into the stand of trees. In a few seconds my jeans and shorts were down and I was on all fours, and I found out just how bad he wanted to hump me. His dick wasn't a foot long, and his knot wasn't the size of a grapefruit, but he had enough to hang me for almost 15 minutes. I don't know how many times I let him screw me after that, but it was a lot, and he never bothered me when anybody was around, but when it was just him and I alone, I knew what I was going to get.
