Chapter 1
Sarah sat on the edge of her pool, her feet dangling in the water. She nursed a beer as she looked at the sunset. Its red and orange hues streaked across the sky in vivid detail as her sons, Cameron and Tim, grilled dinner. She looked at her twin sons wistfully, their casual posture belying athletic frames. They wore t-shirts and bathing suits, and it struck her as odd to see them clothed like this in the back yard. She wore a bikini, not too revealing, but it felt foreign on her, something she had not worn in a year since discovering her sons.
The "discovery," as she called it, had happened on accident, pent up lust and close proximity in a tent during a family camping trip. Her boys had touched her, explored her, and changed her life. Since then they shared her daily, rutting like animals in heat, filling her with their lust. She had surrendered to them wholly, and it seemed at any time one of them would lift her skirt or unbutton her jeans from behind, pushing her panties to the side and taking her. Then the other, always ready, would follow suit. She had been the constant focus of their endless desire; it was heaven, she mused.
There were some unintended, and welcome, side effects to their lifestyle. Always a curvy woman, she had toned up and looked better than ever from their constant, vigorous fucking. She felt more confident, and her business was doing better than ever from that new attitude. And her boys, her wonderful sons, were happy, content to indulge their primal desires.
As she looked upon them she felt an energy, a hot desire stir like a flood inside her. She had to clamp her legs together to control it. The boys were joking with each other, laughing boisterously, and what she wanted to do right then was pull them away from the grill, sink to her knees, and take their cocks in her mouth. Their manhoods, as identical as they, were average in length but thick, and she loved the solidity as she held them in her hands at the same time. But her desires would have to wait.
She stood up, stretching, and gave them one last, longing look before heading inside. She paused by the back door, peeling her bikini bottom forward a bit. She was soaking wet, and glad her bikini was black to hide it. She shuddered with desire, and then adjusted her suit and went back into the house.
"Come on, Sally," she said as she reached the guest bedroom. Behind the door her younger sister spoke.
"I can't, I look awful."
Sarah sighed. Over the last year, where Sarah and the twins discovered every inch of each other, Sally had gone through a bitter divorce. When Sarah had gotten a divorce in several years ago, Sally and their mother had been unrelenting in their judgement. And now that it was Sally's turn, Sarah had invited her to stay with them and pick up the pieces of her life. Sally had been mortified by her sister's generosity in spite of how Sally had treated her, but had accepted the offer. Sally's presence was severely curtailing Sarah's enjoyment of her sons, but family was family and Sally needed help, financially and emotionally.
"Open the door, the boys are outside," Sarah said kindly. After a moment the lock clicked and Sarah entered the bedroom. Sally stood, covering her body with her hands. She wore one of Sarah's bikinis, white and blue striped. It was, like the black one Sarah wore, neither too modest nor too revealing. "You look great," Sarah said.
"I look like a whale," Sally said, aghast. "I don't know what you've done in the last year to get fit, but I can't wear this. Don't you have something more, I don't know, more one piece or something? I didn't think to bring a bathing suit."
"I've got these two, and that's it," Sarah said. She neglected to add that she never wore them. While she didn't parade around the house naked all the time, she always swam naked. The twins, however much or little she wore, were seemingly in a constant state of arousal. The power of youth, she thought to herself. "I think you look fantastic," Sarah added, walking around her sister and giving her a good look. Sally was full figured, with a round ass that Sarah still retained. Sally's breasts were bigger, and she had a little bit of padding, but she was what her boys would call "thick" in a good way.
"I can't go out there in front of Tim and Cameron," Sally said. Sarah took her sister's hands off of her body and held them firmly.
"Yes you can, they're not going to mind," Sarah said. "Come one, I promise."
Sarah led her sister reluctantly downstairs. When she opened the back door she heard Sally's breath hitch. "Relax," she said. She led Sally outside. The boys looked up from the grill, grinning at them.
"See?" Sarah said. "I told you. Besides, the boys appreciate a woman with a figure."
"But I'm their aunt," Sally said.
Sarah stifled a laugh. "They are at an age where they appreciate a woman regardless of who it is, trust me."
"Even you?" Sally whispered conspiratorially. Sarah just smiled and headed to the pool. She slid into the water while Sally walked self consciously toward the grill. The boys were finishing up grilling dinner. She noticed them looking her over and it made her blush. Boys will be boys, she mused.
