Sarah lived in a big house with her brother Jimmy and her parents. She was 19 years old with incredibly sexy figure. Her brother was also 19 years old. Jimmy and Sarah were twins that their mother would sometimes joke that they were conjoined at birth. They were very close to each other. There house was in the middle of big open fields and woods that there were miles in every direction. Back in the woods there was a big pond that nobody knew about it. Sometimes they would sneak off and go skinny dipping in it. They just liked getting naked outside and swimming. There was nothing sexual about it. Otherwise they were nothing but brother and sister. It was no big deal for them that they saw each other naked a lot.
So, they were a bit older and had not skinny dipped in years. Even they had not talked about it at all until that afternoon when they were sitting in the living room together watching a video about nudist lifestyle on her laptop.
"I think I am a nudist," Sarah blurted out looking at her brother.
"Hmm..." her brother said, "I think I might be too."
Both of them remained silent and started watching the video again.
Suddenly she laughed to herself and turned to him and said, "Remember, when we used to run around naked late at night when mom and dad were asleep?"
"Yea," he laughed, "That was a big time ago."
"Yeah," she said, "We should do that again. What you think?"
"You mean right now?" her brother asked.
"No, not right now, but sometime," she replied.
"Yeah, that would be fun then," he said.
Another long pause...
"You know mom and dad are not going to be home for a couple more hours," she finally added.
"Yea, I know," he said, "But it is the middle of the afternoon."
"So what!" she said, "There is not another house around for miles. Nobody will be able to see us. And look at the sky, it's a nice day."
"It's true, but..." he hesitated.
"Please bro, can't you do that for your sis?" she pleaded.
"Ok, but I'll do it if you do it," he said.
"Ok, come with me," she said and stood up.
They both ran to the front door. Before opening the door, they looked at each other for a minute.
"Same time?" she said.
"Ok," he nodded, "Ready... Go."
In a few short moves they both had all of their clothes off. Now they were just standing at the front door looking each other up and down. Sarah looked absolutely stunning which said a lot because she was kind and had a way of hiding her hotness. But there was no hiding it with no clothes on. She looked at Jimmy, her brother's cock.
"You have grown since last I saw you like this!" she said.
He looked at her nice medium sized boobs and said, "Yea, so have you!"
Then he opened the door and both of them stepped outside, cautiously looking around to see if there was nobody there. The sun was hot on their skin. But the breeze was nice and refreshing. It was a perfect weather for nudity. It was kind of funny and embarrassing to watch somebody running naked outside, even two people who were brother and sister.
"Your boobs are bouncing up and down like balloons!" he yelled to her as they ran.
"Yeah," she yelled back, "Well your dick is spinning like a propeller!"
They both laughed and collapsed finally in the middle of the open field. They were both out of breathe and were lying on their backs.
"That was fun," she said.
"Yeah," he agreed.
For the next hour or so they sunbathed mostly in silence, rotating every few minutes or so. Jimmy looked at his sister's beautiful naked body. It was so nice that he wanted to mount her right then and there. He started to get a boner though so he tried not to think about such things. To distract himself, he grabbed a blade of grass. His sister's eyes were closed so he quickly brought the blade of grass up to her pussy. It was perfectly shaved and delicious. He lightly fluttered it on her clit and she gave a yell and sprung up.
"OMG!" she yelled and punched his shoulder, "I thought that it was an insect!"
"Hahaha...!" he laughed, "Sorry, I could not resist!"
"Oh yeah!" she grabbed hold of his medium sized dick and pulled herself close to him, "Well, don't let it happen again!"
His dick throbbed in her grip.
"Oh my god, it moved!" she yelled and let go.
