Rex and Nia were enjoying their naked freedom and fun as they walked down by the river, Rex and Nia were wearing only a smile and left their clothes behind. The feeling of Rex and Nia's total nudity made them feel even more stimulated and excited than usual as they walked nude along the wooded river bank for about half a mile, feeling at one with nature and not really caring if anyone saw them or not, Rex and Nia was relaxed and enjoying being in his natural state, his initial nervousness at being so far from clothes had gone.

At the end of the wooded area, the river bank opened up into a large open field bordered by a small ridge which ran along the side of the local railway line. The open farmland bordering the river looked very inviting and throwing caution to the wind, Rex and Nia walked out from the cover of the trees into the open green pasture, totally exposed to both sides of the river and anyone who might be watching.

Further along the river bank, about 100 yards away, Rex and Nia decided to go for a swim. They waled to a shallow and gravelly area of the river as he cautiously paddled out into the middle. Wading deeper into the river, Rex and Nia swam across a deep pool and emerged on the opposite bank. The sun was warm on Rex and Nia's naked bodies, so he decided to lie out on the grass and dry off. The nudies felt so exhilarated and relaxed.

As Rex and Nia lied naked in the sunshine for about 10 minutes, they felt their skin against the grass as they slowly stroked their private areas, enjoying the warmth of the sun and the feeling of being naked.

5 minutes later, they swam back and flopped down on the grass to catch their breaths. Rex and Nia smiled at each other, watching each other intently, Rex's penis started to stiffen and become erect while Nia's vagina began to leak. Nia said, "A nice way to sunbathe is in the nude."

While Nia looked Rex up and down appreciatively, Rex giggled back as he did the same. Rex was flattered at how much Nia was staring directly at it. Then, Nia said, "I think maybe you need to go get your clothes before something happens to you."

As Rex stood there motionless, not knowing what to do, he reminded her, "Uh, Nia? I don't have any to put on."

Nia laughed, "Just kidding."

Rex giggled at her joke, then without thinking or even realizing it, Rex was stroking his cock as Nia watched. He couldn't believe what he was doing and as Rex looked up at Nia, who gave him a gentle smile. It didn't take long for Rex to ejaculate and as the last of the cum dripped from the tip, Rex was then kissed by Nia.

While Nia drew they eyes from Rex's penis and smiled at him, he turned and walked down to the river edge. Nia was right behind him, watching Rex intently and staring at his young firm bum. A few minutes later, Nia said, "Is there a bathroom nearby? I have to pee."

Rex said, "I don't think there is one."

"Oh. Then I'll just pee out in the open. Being naked, the world is our toilet."

Pee came out of Nia's vagina, she giggled as a naked Rex watched her piss. Once she stopped, they kept walking until they reached a lake. Rex and Nia then sat on their butts to do some more sunbathing.

As Nia stared at Rex's erect cock, his penis was throbbing with excitement while he giggled at Nia's wet pussy. They so wanted to masturbate in front of each other's very eyes. Nia told Rex, "If you wanna fondle yourself, go for it."

Smiling, Rex said, "Will you also finger yourself as I touch my penis?"

"Sure."

Rex started stroking his penis gently while Nia eyes were fixed on his dick as he stroked, Nia fingered her vulva in front of Rex while watching.

Soon, Rex's penis started to twitch and pulsate in his hand while Nia's pussy leaked out a river of her womanly juices. Very quickly, hot white semen started to spurt out in long, thick jets from Rex's dick and Nia's cunt.

Climaxing, Rex and Nia gasped loudly as they kept on spurting their hot cum on the grass, leaving white gushes of semen floating and then slowly sinking to the ground. As Rex and Nia finished, they let go of their genitals and lied down, Nia looked up into his face and asked, "Did that feel good?"

Rex just nodded, he and Nia were enjoying the feeling of having just cum in front of each other in public.

Then, Nia kissed Rex's lips and they cuddled before going home.
