Amber and Bobby – Fraternal Twins with benefits

It was scorching hot August day as we walked along the old Alabama dirt farm path after finishing a load of chores. My sister Amber was walking in front of me as we neared the side of the creek bed that ran through our farm. She was 16 years old and my fraternal twin. Amber had developed into a woman over the past two years and unlike our prepubescent years when mom would bathe us together and we would run around in little more than our under shorts I now had only seen her fully clothed over the past several years. Amber stood 5’4” and weighed 112 pounds with shoulder length auburn light blonde hair. She had deep blue eyes and an angelic face. Guessing I would say she had C cup breasts that were perky and she had the greatest set of hips and ass that I had seen on any of the girls in school, firm, tight and perfectly rounded sitting atop her long sexy legs.

I had developed too over the past years and now stood 6’00” tall and weighed 168 pounds. Our hair and eye color was the same but I was tall and lanky in stature. Puberty had also left me with a cock that grew instantly to 6” in length and typically stayed rock hard for most my waking hours. As weird as it seemed in my head I always looked at Amber and wondered what she would look like and feel like naked. I never acted on it but the thought was in my head daily.

Amber and I were both soaked with sweat as we walked the path to return to the house. Amber like I was wearing a pair of worn denim overalls and had her hair pulled back into a pony tail. I was not wearing a shirt under my overalls but Amber had on a short sleeved white t-shirt beneath her overalls that had become soaked with her sweat during the day and was revealing her white bra straps clearly. As we got under a group of trees in some shade at the side of the creek Amber stopped for a moment and remarked about how nice it would be to get into the water to cool off. I stopped and replied to her that it would be great but we would get our clothes a mess in the muddy bank and mom would take a switch to both of us. Amber laughed at my reply and said “Not that long ago we would have just shed our clothes and never thought nothing about it.” I told her she was right but that was in the good old days. She replied that she wished we could return to those simpler days again. We stood and talked enjoying the shade and slight breeze when Amber surprised me and said “Bobby, why don’t we just go swimming like we used to? Up until a couple years ago we would stop here every day and take our clothes off and swim around and have a lot of fun.”

I was thinking about the many years that we did just that and our only concern was mom or dad finding out we were in the water. We never got caught and it always seemed natural for us to do. I nodded my head and told Amber it sounded like a good idea. We then both stood for a second and starred at each other and then I unfastened the top strap of my overalls and we both started getting undressed. I don’t think either of us really looked up until we were both done and then our eyes met again. Amber was starring up and down my body as she stuttered and exclaimed “Gosh Bobby, you’ve changed since last time we did this!” My eyes were taking in the gorgeous curves of my twin sisters tender young body and it was hard for me to speak. I realized that my momentarily soft cock had sprung into an instant missile standing straight out.
