Cynthia and Carl had been raised in a very open family. They were twins and had been close for the entirety of their lives. They were born to their loving mother when she was just eighteen. Their dad had done the 'right thing' by Glenda and had married her before she started showing. He was also eighteen at the time and both were still in high school. The family had grown up in rural California which was much different than the crazy liberal society of the rest of the state.
Carl and Cynthia's dad, Larry, had worked hard to provide for the family and had never been able to go to college. He became a welder and at the age of 22 had his own business. By the time the twins were in high school, their dad had a thriving business employing over fifty people. He had done well for his family and they were very appreciative of the life that he had given them.
Glenda had spent most of her young life caring for her babies. She loved her twins and spent every waking moment with them. As a devoted parent, she made sure that they had everything they needed and what ever she could get that they wanted. She home schooled them until they went to high school. It was just beyond her ability to teach them at that point. She had done well with them and they were more than prepared for the transition. Glenda had started college when the twins had started high school.
The kids were active in high school. Both were gymnasts and both ran track. Their academic standing was unrivaled. They were at the top of the principal's role every time. And they were gorgeous. Now, they were both model material. Carl was six-foot-one and was a muscular one hundred and ninety pounds. Cynthia was five-ten and weighed one-hundred and twenty pounds. She had medium sized breasts, 'B' cup. Both had blonde hair and blue eyes. Cynthia's hair was shoulder length and curly. Carl's was curly and blonde as well but he kept his cut more modestly.
They had inherited most of their attributes from their mother. She too was a beautiful woman. At 37, she was at the peak of her prime. She worked hard to keep her body beautiful and in shape. She was five foot eight, weighed one hundred and thirty pounds and had a beautiful 'C' cup thirty-eight inch bust.
Growing up, the twins had been educated by their mother's open and frank discussions. She had taught them to respect their bodies. They were very in tune with what they should know about masturbation, body changes, hormonal drives and copulation.
Carl had always loved his sister; very deeply. He was extremely protective of her. She relished his attention too. She never resented his interference in her dating when he thought a guy was not good enough for her. And most weren't. She was the same with him. She wanted to insure that his heart remained intact and that no 'heart-breakers' or 'floozies' got their claws in him.
Because of their poverty early in their lives, the two had slept in a bed together until they were about nine. That is when their dad's work had started paying off and they moved into a house with more than two bedrooms. Even then, they would often fall asleep with each other on occasion after watching movies or just talking. After all, they were twins. Twins are supposed to be that close.
As they became older, Carl began noticing Cynthia in a different way. He caught himself looking at her body a lot. At first it was an appreciative admiration. But this soon turned to something deeper. Carl often saw more of his sister's body than most boys his age see of theirs. Cynthia had often been the object of his fantasies. As he began to grow into manhood, he also became fascinated with his mother's form. Unlike Cynthia, mom was busty and had a more voluptuous ass. She was in shape, but there was just more of her to be in shape. Cynthia was tall, thin and had smaller breasts than her mom. So Carl would switch back and forth in his fantasies between the two offering him a greater variety of imagination.
Then came the day of their eighteenth birthday. They had less than three months of school left before graduation and both had received multiple scholarship offers. Their dad asked if there was anything that they wanted to do for their birthday. "Anything?" asked Cynthia.
"Anything," dad had replied.
"We want to go on a vacay to Hawaii," she replied.
"Okay, then, we'll go during winter break from school," Larry had said.
As the weeks led up to the trip, the two would spend hours discussing their plans. On the night of their eighteenth birthday, after a long planning session, they had fallen asleep in Cynthia's room. Cynthia was wearing her typical night shirt and panties and Carl his sleep shorts. At about four AM, Carl woke to find his sister laying in the crook of his arm. His hand was on her breast. He couldn't move. It felt so good; the feel of her t-shirt-clad tit under his hand. His cock was hard as it frequently was when he woke. He lay there for a while just relishing the feel of his sister's breast in his hand. He also felt a growing urge in his shorts. He couldn't resist it. He slipped his other hand beneath his shorts and he began to stroke himself. He gave no thought to anything but how good it all felt. Cynthia's shirt had rode up during the night and In the glow of the night light, he could see the outline of her pussy through her panties. He was so focused on the beauty of her pussy and the feel of her tit that he didn't notice that she had awakened. Her eyes were wide open.
Cynthia watched as her brother stroked his cock. He had now pulled it out of his shorts and she saw it hard for the first time as he rubbed it before her. She had seen the imprint of it through his pants before but now, here it was in plain view. She decided to just watch the show and not let on that she was awake. He was so focused on staring at her panty-clad pussy and feeling her tit, that he had no clue that he had an audience.
He unconsciously squeezed her tit. He felt her nipple grow stiff in his palm. He stared at the mound covered only by the thin material of her panties. Through the nylon, he could make out the split between her lips. Since her shirt had ridden up in the night he could see her flat belly gave way to a slight bridge-gap below her navel where her panties were held taught by her hips providing a crack through which he could see further down he tummy. The light was not good enough to see through this opening but it excited him none-the-less. He quickened the tempo of his strokes. He was going to come but he gave no thought as to the consequences of it. It felt so good looking at her; feeling her. The first shot of cum landed on Cynthia's shirt. Then his hips bucked as he shot more and more of it. Some landed on her legs and panties.
Cynthia felt him coming and felt each string of cum hit her. She wasn't grossed out about it. She was amazed that she liked it. It actually turned her on that her brother was so excited by the feel of her tit that he would come. She could feel her own moisture in her slit. She watched as her twin pumped his cock milking his cum from it onto his hand. She had a sudden urge to lick the cum from his hand. She wanted to lick it from his cock.
Carl let his cock slip back under his shorts. He wiped his hand gently onto his shorts. He felt nothing but good. He didn't even consider the mess that he had just made on himself and his sister nor the potential consequences. It just felt good. He soon drifted back to sleep.
Cynthia was wide awake. She was so turned on that sleep was not an option. Soon she could hear a change in her brother's breathing. He was sound asleep. His hand was still on her breast and it felt so good. She slowly moved her hand to her leg where she had felt his come land on her. It had run a bit but the remnants were still there. She slid her fingers across her flesh scooping up all that she could and slowly brought her fingers to her lips. She lapped at her fingers and tasted the sweet and salty flavor of her brother's sperm. She needed more. Her hand explored all the spots where she had felt his cum land. Each time she would lick her fingers clean of the gooey stuff. She scooped the last bit but she saved it and let her cum-covered fingers slide into her panties. She felt the warm moistness of her pussy as her fingers slid over her slit smearing her brother's cum onto her. Her fingers explored the regions she knew so well. Cynthia loved to masturbate and did it often. Sometimes she would do it several times a day. At times she would take her time and enjoy her whole body. But this time, she was so excited at having watched her brother come, she was not holding back.
