When I was a teenager, my younger brother and I stayed at my grandparents farm in upstate NY for the summer. They had us working with chores from morning until night. Usually by mid day, we were hot and tired. We would walk with our grandfather to the far end of the property and down a path to a large swimming & fishing pond for afternoon break. It was just ‘us guys’. My grandmother never left the yard, so we’d swim naked with our grandfather then we’d all dry off sitting by the shore. Feeling the breeze without clothes on felt especially good. One afternoon, after watching my grandfather laid out naked on the grass, my dick grew until it stood up at full attention. My little brother got my grandfather’s attention to look what was happening to me. I was so embarrassed but my grandfather laughed and said it was nothing. ‘All men have that happen now and then’. Then told my brother to go back to the house and help out my grandmother.
Once he left, I apologize to my grandfather about my boner & told him it does this a lot lately. My grandfather said it happens to him a lot too. As he said that I saw that his dick was so engorged it was throbbing. He pulled me closer and explained that I was becoming a man and I was becoming of age to make babies. I told him my dad had ‘the talk’ with me months ago, but I had questions I didn’t want to ask then, like ‘how do I turn it off’ and ‘what do I do in the meantime’. My grandfather wrapped his hand around my boner and started to slowly message it. “You’ll work it out. Like this”. His hand felt so fantastic I had my shot jizz all over both of us. “Good boy” he said. “Even I have to work it out now and then”. My grandfather grabbed his boner and rubbed it until he ejaculated over our bodies, too. We cleaned off in the pond, grabbed our clothes and returned to the farm; talking and laughing along the way.
Later that night, after my brother was asleep, I masterbated myself thinking about my grandfather. My thoughts still return to him, his enormous stiff boner and how his hand felt so nice.
