Last wednesday morning my buddy called and said Dad is going to start baling hay today about noon, can you come over and help me and my brother haul? Yeah no problem, we're both 18, his brother is 16, they came over and helped us with ours. I got over there about 11:30 his brother was raking, his Dad was just about ready to head to the field with the baler. My buddy told him we'll gas the tractor and be right behind you, about two months ago I let him have anal sex with me, and have done so several times since then. After filling the tractor he said, if you want to fuck we got time, he'll have to make a round before we start picking up anyway. I was game so we went inside the tractor shed, I was bent over with my hands on the hood of the riding mower, he was standing behind me with his hands around my waist fucking me like crazy. He'd just said I'm going to fill you full of cum when we heard his Dad say, what in the hell are you two doing. He was humping hard and holding his load back so he could explode it deep inside me, but when we heard his Dad he pulled out fast and shot his load straight between my cheeks. I stood up and turned around, his Dad had the most bewildered look on his face, he looked at us and said, I wish I hadn't forgot that oil can. My buddys dick had completely dissepered, I could feel his cum slowly sliding down my legs, his Dad said this is going to stay between just the three of us, but if I ever catch you again, or even hear about you doing it, I won't just talk. We got the hay hauled and put away and I was asked to stay for supper, I've been over there three times since then, not to get fucked but to work, and each time it's been hard to look at his Dad.
