I was at our family outing at a campground. I hate these functions, but my parents forced my hand. I thought everything was going smoothly until my sister Meg started to act up. My sister was always pulling these stunts. She was always a diva when we were growing up and things only got worse as we became adults. I don't even know what her problem was that day. All I know was that my mother was getting upset.
I finally couldn't take it anymore. I went over to my sister and took her by the arm and started to march her away from all the people there. Meg was really pissed at me as I took her away from everyone and we walked into this wooded area.
"What is your problem Meg?"
"My sister was wearing her usual attire. She had taken to not wearing a bra these days. Maybe she was trying to show off her big tits. I really had no idea why she dressed that way at a family function.
"You're such an ass, Greg," she said to me.
My blood was really beginning to boil right about then. I put my hands on her arms and tried to shake her. To my surprise, my sister reached out and slapped me on the face. I think it took both of us by surprise. Meg had this look on her face that said she had gone too far this time. I just lost all control. There was this large tree nearby where we were standing. I turned my sister around and took hold of her arms. I pushed her hands onto the trunk of this tree.
To this day, I don't know what came over me. I lifted up Meg's shirt and pulled it up to her shoulders.
"Greg, No!" My sister cried out.
My hands went to her waist and I yanked down my sister's pants and panties.They fell down to the ground. My sister seemed paralyzed as I reached around with both hands and placed them on each of her breasts. My sister's nipples were all hard. I could feel my dick getting hard in my pants from all this fighting. I began to squeeze Meg's tits and to my shock, my sister started to moan. She was actually getting into it.
I must have fondled my sister for a few minutes when I reached down and unzipped my pants. I pulled my dick free and started to rub my already hard prick up and down her crack.
"Oh my God!" My sister cried out.
Looking back on it, I didn't have any self-control left in me. I used my hands to slide my sister's legs even farther apart. The head of my dick managed to find Meg's opening and I pushed my mushroom into my sister's pussy.
"Oh Fuck!" Meg shouted.
I was going to have my payback for all my sister's nonsense. I was thrusting into my sister's pussy now. To my surprise, Meg was getting into it. Her pussy muscles had me in a tight grip as I fed her every hard inch of my rod. I only hoped no one came looking for us. I could just imagine a family member seeing us fucking out there in the woods. I drove my cock inside my sister the whole way. Meg was now pushing back on me. We were getting into a fucking rhythm as Meg held onto the tree trunk.
I wish I could have held out longer. We must have gone twenty minutes or so when I felt like I couldn't hold out any longer. I know I was being stupid, but I couldn't bring myself to pull out. It probably wasn't wise to be unloading inside my sister. That is exactly what I did anyway. I thrust a few more times into my sister's tight hole and I sent a hot stream of my cum into Meg's pussy.
