I grew up on my grandfather's cattle his side of the family all lived on the property in separate houses. I am the youngest kid. And we all joke about me being the favorite grandchild because out of the 5 kids on the property I was the one who always had to ask to swim in his pool or rides the go carts and he never told me no. But only my oldest and only female cousin and my mom, and Grandma know why.

My oldest cousin and I were playing truth or dare with a boy her age from down the road one day at my house because my parents were gone, they were 13/14 and I was 9 well my cousin dared the other guy to fuck me and the rule was already made that we had to do anything. So I was naked on the couch getting fucked when my grandpa walked in my house and caught us. He made the neighbor leave and starting scalding us. I was covering myself but still naked and he called my mom and told her what happened and made me talk to her and she said grandpa can punish me however he wanted and that I better obey him. Well when they ended the call he asked my cousin why he saw what he did and she said it was her idea she wanted to see it.
He let her watch as he made me blow him before he had me sit on his lap. Yes that's right he fucked me. He called my mom afterwards and told her what happened and she was ok with it. When she got home she told me that I wouldn't be in trouble anymore but that it had to be a secret. And made sure I was ok. It was a several months later before it happened again after I broke a fence in the pasture from horseplaying. That time he just sent me over the tailgate in the pasture after helping me fix it. And it kinda just turned into a casual thing that was not discussed openly but that made it more fun...
