The hike around the lake was all set, they even packed a lunch and headed out at 9 am. The drive took only 45 minutes and as they put on the backpacks they began to hike at a fast pace to begin with. They all worked up a good sweat as the heat of the day was rising. The sun was nearly right above them and the noonday heat was starting to be oppressive.
They had hiked about four miles and were at the other side of the lake. They had followed the paths but it wasn't an easy hike under most circumstances. By the time they reached the little picnic area they all were drenched in sweat. Rebecca sat herself down at the picnic table that someone had long ago hauled across the lake by someone and deposited it at this clearing bordered by a grass field next to the lake.
After everyone had shed their packs and placed them on the table they realized how hot they were. Clothes started to fly off as everyone was now in a rush to cool off. It had the opposite effect though. Julie immediately went over and planted a big wet kiss on Becca's lips, she responded and soon their embrace was that of two lover who had found each other after a long absence. Not to be left out Rebecca's brother went over and started to rub Julie's ass and torso from behind even reaching around her to caress his sisters body. They soon turned, brought him into the fold and began kissing him also.
Needing a place to lie down they soon moved to the field and lay down in the tall grass. Julie lay down and her mouth went right to Rebecca's pussy. She could smell her musky scent from the walk and she was very turned on. After dipping her tongue into Becky's snatch she lifted her head and said,
"I see you had a head start on us," and then went back to her ministrations on Becky's clit.
Becky was licking her brother cock and he in turn was kissing his way up Julie's legs to her pussy. Soon there were groans all around as each was getting close to orgasm. Julie came first and she pulled him off of Rebecca's mouth telling him she wanted him to fill her up!
Rebecca was getting there and with her brother pounding away at Julie their guttural grunts as he fucked her deep coupled with the slapping of his balls on her skin every time he thrust in her sent her over the edge about the same time her brother grunted he too was cumming.
Afterward as they lay in a heap Julie asked, "Who came in you this morning?" Her brother looked puzzled as shortly after they woke this morning they both took showers and left. He hadn't fucked her this morning.
Rebecca's laughed and went on to say, "Well when we woke you were in the shower so I went to use Mom and Dad's, only Dad hadn't left for work yet. He was running late so I just hopped in with him. It didn't take too much of soaping of his cock before he was rock hard.
"He told me he didn't have time this morning, as he was late already so I just grabbed his cock while turning and bending over and put it right up against my pussy. I told him 'just fuck me quick and I will be happy' so he grabbed my hips and plunged into me. He didn't take long, he was real fast. He then got out and got dressed and left while I finished. When you got out Bro he had already fucked me and gone to work."
Now he understood Julie's comment and replied "I see you had a head start on us" and he smiled.
They lay there for only a few more minutes before they realized they should cool off in the lake. They all ran naked and dove into the cool water. Splashing around did the trick as soon they were cooled off and ready to rest in the tall grass by the picnic table.
They spread the cloth they brought and sat upon it still naked and got out some lunch and drinks. The sun felt good to them all and soon after lunch you could see three naked bodies lying down on the cloth sunning themselves. Turning every once in a while so as not to get a sun burn. They had even brought sunscreen and took turns rubbing each others skin to protect themselves.
After a time Rebecca's brother nodded off and Julie and Rebecca began to talk. Rebecca admitted to Julie that she had not slept with that many men. She had slept with the same number since she had come home from school than the previous four years. She had only had three lovers previously and one was her brother. She told Julie about having sex with a professor at school who was much older than her. She told her about her meeting an older man online the one that wrote the story that Julie had read, but she had never met him face to face.
Julie related that she had lost her virginity to a boy at college and besides him her only other lovers had been Rebecca's brother and her own father just recently. As for lesbian encounters Rebecca had been her one and only Sapphic adventure. Both laughed as they now thought how much they were enjoying their new adventures. They talked about their sexual preferences and what they hadn't tried but would like too.
This was beginning to turn them both on and soon they were embracing and kissing deeply. They lay entwined in each others arms and legs and it was only natural that their hands explored each others breasts and pussies. After a time they naturally moved to a sixty-nine position so that each could enjoy the taste of their respective pussies.
Soon they were so into licking each other and getting closer to orgasm they didn't even notice Rebecca's brother had woken and was calmly stroking his stiff cock while watching them. They were too enmeshed in their own excitement to notice and when their moans got louder, first Julie then Rebecca stiffened and orgasmed they lay there reveling in the moment. It was then that they noticed the hard cock beside them.
Becca's brother started to say 'what about me' when they both leapt at him and began to suck him and jerk him off together. They took turns sucking and kissing and licking his shaft while he moaned his appreciation. He loved the attention and soon they had a rhythm going that was sending him over the edge. Julie noticed this and stopped Rebecca before she made her brother cum.
She said "I want to feel your cum in my ass, I have never had anal sex."
With that she turned over on her stomach and wiggled her butt provocatively in the air. Becca responded by rubbing some of Julie's wetness over her rear hole and slowly inserted a finger while her brother positioned himself for entry. He knelt between her legs and with Rebecca guiding his cock he placed the tip at the entrance and gently pushed.
His cock slowly entered and he felt her sphincter muscle closed around the head of his cock. He waited just a moment and pushed again and slowly pushed the length of his cock all the way in Julie's ass. When he bottomed out he stopped to let Julie adjust to his cock. He knew that she had never done this and wanted to make sure he got to finish the job and cum in her ass.
