We entered the barn and as before I walked straight back to the bailed hay Burt at my side. We both jerked to a stop as we saw Ann on her knees in front of my son with his thick cock in her mouth. We were too shocked to say a word and before Burt could get his breath I pulled him away and made our way to the front of the barn. I could see he was about to explode so I took him by the arms and told him they were just kids and were playing at learning about sex as any kids would. Besides I thought if he remember his youth maybe he had done the same thing. He seemed to calm down and I took him by the hand and lead him to the lower level of the barn.
