Adam and his sister, Evelyn, have a very personal relationship. The origin of their relationship was told in the story "Cabin Fever." (Literotica, https://www.literotica.com/s/cabin-fever-49, 4/30/2020). Their story expanded to include their mother in "Georgia." (Literotica, https://www.literotica.com/s/georgia-2, 6/5/2020).
It's now the beginning of June and Adam and Evie are still living together in the family cabin in the Upper Peninsular of Michigan and, if the governor's orders are valid, it looks like they'll be there for at least two more weeks.
I was sitting on the porch in front of the cabin, sipping iced tea, enjoying the warmer spring weather and watching the clouds and birds outside when my sister, Evie, came out of the cabin and sat next to me. She, like me, wasn't wearing any clothing except on her feet. We'd given up clothing within minutes of arriving at the cabin last April.
That was an easy decision. Evie and I had lingered at the cabin last March when Evie, her about to be former husband Roger, and our parents had a weeklong stay and everyone else had left for Ann Arbor. We danced around with each other, alone in the cabin, until, surprise, we fell into bed and screwed like rabbits. We discovered many things about each other including how wonderful the sex was and that neither of us was too attached to clothing. The decision to 'go native' was easy when we arrived back without anyone else last April.
Mom, she wants us to call her Georgia, dropped in unannounced in May for four days and took control of the routine in the cabin, including the sex and dress code. When she finally got dressed and left for home, we sighed in relief and began working on a long-term plan for our relationship.
"Adam," said Evie sitting next to me, "would you like to take a walk with me?"
"Absolutely," I answered, downed the last of my tea, stood up and offered her a hand. We walked, hand in hand, down the path toward the forest. When we entered the forest, the temperature dropped twenty degrees in the shade. Evie's nipples perked up with the cold. I noticed but I didn't point it out to her since she became embarrassed when her nipples acted independently of her conscious effort. My traitorous cock noticed and began to grow independently of my conscious effort.
"Did my nipples do that to you?" asked Evie as she reached for my half-enlarged erection.
I laughed along with her as we strolled deeper into the dusky forest. Evie couldn't resist gently playing with my cock and we walked close together with my arm around her waist.
"That's mom and dad's tree," commented Evie when we entered a small, sunlit clearing and she pointed to a large oak directly in front of us.
"It is," I answered.
"You know what they do against that tree, don't you?" said Evie.
"I do."
"Well, I think we should use the tree in their honor," she suggested.
I'm never reluctant to follow Evie's lead, especially when it leads to sex. Evie turned and pressed her body against mine. She kissed me and rubbed her breasts against my chest, her stiff nipples tickling my skin. She backed up, pulling me with her until she was against the tree. Her left leg came up over my waist and my fully erect member found her warm and familiar passage. I slid inside her and she pressed down against me. I pushed back against her until she could lift her right leg around my waist. I was holding her up, supporting her against the tree as I moved vigorously inside her. We continued like that until I came and slid from her.
"That was for you mom," Evie said as she got her feet back on the ground.
Life at the cabin was like that. Evie and I lived, mostly without clothing, most of the time. We had sex often, when either of us wanted to. Some evenings we would sit, holding hands and watch a movie over the satellite cable. Other evenings we had repeated sex and chose to watch the movie some other evening.
It was a perfect environment. I was an independent contractor and could work remotely with the cabin WiFi and the satellite internet service. We lived simply only needing to keep the generator fueled and an occasional trip to get food and more fuel. We read novels on our tablets between sexual encounters and we planned our future when the stay at home orders expired.
We were pretty much settled on living together in an environment that was new to us. We were young, in love and had the same last name. If people drew the wrong conclusions about our relationship, we weren't going to correct them.
The unannounced visit of our mother, Georgia, last month, unsettled us for a time but we began to understand her motivations and, since she was unavoidable, we were determined to live with however it would develop.
My phone rang in the middle of the afternoon on a Wednesday. Georgia was on the phone telling me, and Evie, that she and dad were coming up to the cabin for a week. She told me they would arrive late on Friday and planned to stay until the following Saturday.
Evie wasn't thrilled with their plan to stay for a week. Georgia's previous visit had resulted in sex between the three of us but this trip dad would be with her. His presence would add significant strain on our unrestricted sexual conduct and dress code. I agreed with her but I suggested that mom knew what she was doing and having dad along wouldn't change her plans significantly. I didn't know exactly how but I cautioned her to let mom lead and follow along. At worst, it would only be a week of sneaking off into the forest, lake or taking advantage of those times when mom and dad left the cabin together.
We spent the day Friday, washing the sheets and making the beds in both bedrooms. We straightened the rest of the cabin and removed all signs of our sexual romps. All day, Evie encouraged sex at an increased rate, rationalizing she needed to store enough sex to last the week.
Mom and dad arrived late Friday and we had a late supper after stowing their gear in the spare bedroom. We had nice evening catching up on happenings with family and friends over a bottle of white wine. We watched some late news and mom suggested it was time to retire.
I gathered a pillow, sheet and blanket from the bedroom and began to create a sleeping area on the sofa. "What are you doing?" mom asked as dad left the room.
"I'm going to sleep here," I answered her.
"Don't be silly. Sleep with Evelyn like every other night. We don't want to disturb your routine."
"But what about dad? What will he think?" I asked.
"Don't worry about Ralph," she said. "He'll be cool with it. I'll see to it."
"If you think so," I said, picked up the linens and headed to the bedroom.
Mom smiled and said good night as she went into her bedroom and closed the door. Evie was surprised when I returned. "Really?" she said when I told her what mom told me.
Evie and I had restrained sex that night with the bedroom door closed. We slept and had another quiet sexual session before sleeping again. In the morning, after a lingering coupling, we dressed and went into the kitchen for breakfast. Mom and dad's bedroom door was open and they weren't anywhere inside the cabin. We made coffee and went out on the porch to enjoy the morning air and wait for them to return.
About twenty minutes later, mom and dad strolled out of the forest, holding hands, wearing light footwear and nothing else. They were both naked as the day they were born.
"Holy shit," exclaimed Evie before they were close enough to hear her.
Mom's nipples were extended from the cool of the forest and her pubic area was completely shaved, a holdover from her last visit. Dad's relaxed and circumcised cock swung slightly side-to-side as he walked. He wasn't very large relaxed and I guessed he was a grower rather than a shower. Mom waved as she and dad drew closer.
"Good morning, you two," mom called. "We got up early and went for a walk while waiting for you. I hope you haven't been waiting for long."
Evie seemed to have lost her voice. "Not a problem," I said. "We've only been up for a few minutes. Did you have a nice walk?"
"We did. We visited several of our favorite places," she said with a wink. "I hope you both made good use of the extra bed time this morning while we were walking," she stated with another wink.
Evie seemed frozen. I helped her up and we all went into the cabin. Mom got breakfast going and we had a lingering meal with mom and dad naked and Evie and I dressed. When he finished his coffee, dad excused himself and headed for the bathroom.
Mom used his absence to suggest, "You know, you guys don't have to wear clothing if you don't want to."
"I appreciate your suggestion," I said. "We'll talk about it."
"You want me to be naked in front of dad," a shocked Evie interjected.
"He won't be a problem," mom said. "He's perfectly comfortable in front of you."
