"I was beginning to think you'd never get here," Aimee said as she greeted Kyle and Caitlyn with a hug and a kiss.
"Yeah, it took a little longer than we expected," Kyle said, "but it wasn't too bad."
"It was really kind of fun," Caitlyn chimed in, smiling at her brother.
Carrying their bags, they followed Aunt Aimee into the house. She took them upstairs and showed them their rooms, across the hall from each other. The house was big, too big, but Aimee's deceased husband had inherited it from his parents and Aimee had inherited it from him. She thought about selling the house but it was in a nice part of town, close to the school where she worked, and totally paid off.
"There's only one bathroom upstairs," Aimee said, "but we shouldn't have a problem sharing it."
An hour later, as Aimee cooked dinner, and Kyle and Caitlyn showered and changed clothes after their trip, she thought how nice it would be have someone in the house with her, again. Ever since Daphne moved out last year, Aimee had been very lonely.
Looking back, it had probably been a mistake to let Daphne go. She had been Aimee's first gay lover, after Aimee's husband died, and Aimee's first real love. However, Aimee was a third grade school teacher, in a fairly small town. Being single and sleeping with men was bad enough. Coming out as gay would have had serious repercussions. Just the fact that Aimee was renting a room to another woman had started the gossip mill working. Daphne was unwilling to keep their love affair a secret any longer and since Aimee was unable, or unwilling, to acknowledge it, Daphne left.
As soon as her niece and nephew arrived, things seemed different. Aimee felt different, happy, alive, energized. It was too bad they could only stay a week.
The thought came from nowhere and popped into Caitlyn's head. "Did...you call...mom?" she asked.
She was leaning forward, over the bathroom sink, as her brother, standing behind her, slid his long, thick cock in and out of her pussy. "Jesus," Kyle said, "what the...yeah, I called her." He was fucking his sister with long, deep, hard strokes, making her gasp and whimper.
Kyle threw his head back and groaned as he thrust the entire length of his cock into Caitlyn. "Ooohhh, fuck," Caitlyn moaned, not wanting to be heard by Aunt Aimee. The walls of her pussy convulsed around her brother's erection, milking it as its load of sperm spurted into the condom.
Kyle stepped back and pulled the latex sheath from his wilting penis. He dropped the cum filled tube into the toilet and flushed. "See you at dinner," Kyle said as he closed his robe and headed for his room.
Caitlyn cleaned between her legs with a damp washcloth, slipped on her panties and carrying her bra, hurried into her room. Neither had noticed that when Kyle tossed the condom into the toilet, he missed, and it fell on the floor.
A minute after Kyle and Caitlyn went into their rooms, Aunt Aimee climbed the stairs and went into the bathroom. She lowered her jeans and panties then sat down to pee. Sitting, she noticed something on the floor and picked it up. It took her a second to realize what it was and a second more to realize where it came from. When she did, a sudden rush went through her and her vagina was suddenly very wet.
She lay it across her other hand and studied it. As though in a dream, Aimee held both ends of the cummy tube in her fingers as she raised it to her face. First, she smelled it, inhaling the strong, musky fragrance then she leaned her head back, released the open end and let her nephew's still warm cum fall into her mouth. It tasted wonderful and it felt great, trickling down her throat. It had been a long time since she had male sperm in her mouth and Aimee had forgotten how much she liked it, the taste, the feel, the smell.
As she savored the slimy cream that she held in her mouth, Aimee lowered her hand and slowly rubbed her clitoris.
Kyle and Caitlyn came downstairs together. Kyle was wearing a white T-shirt and gray shorts. Caitlyn had on a yellow tank top, over a flesh colored bra, and green shorts. Her feet were bare and Kyle was wearing white, running shoes. Aimee was dressed in blue shorts and a red, sleeveless pullover.
They ate spaghetti with meat sauce, and garlic bread, for dinner. As they ate, and cleaned up afterwards, the three talked and laughed as they told each other what they had been doing since the last time they were together.
With her newfound knowledge of Kyle and Caitlyn, Aimee found herself looking at them differently. She had begun feeling an attraction to her niece and nephew, especially Caitlyn, when she attended Kyle's sixteenth birthday party. Caitlyn was not yet fourteen but her body was already more developed than most girls five years older. Aimee never let herself even think about having sex with them. They were her sister's children and just kids, then. Now, Caitlyn was eighteen and Kyle was almost twenty. After two years of college, Aimee thought, Kyle probably had slept with several girls. And the way things were in school these days, Aimee would have been more surprised to learn that Caitlyn was a virgin than to learn she was not. Even so, discovering that they were sleeping together was a surprise.
Aimee wanted them to know that she knew they were sleeping together and it was all right. She knew that her ideas, especially about sex, were different, maybe even perverted. She kept her ideas to herself because she knew most people would not accept her or the way she thought. Conventional rules never suited her. Incest was wrong only if you thought it was and obviously, her niece and nephew did not think it was. Neither did Aimee.
Done in the kitchen, they went in the living room. After an hour and a half, it was a little before nine, the last twenty fours, the driving and the sex, caught up with them. Caitlyn was unable to keep her eyes open and Kyle was yawning repeatedly. They each went to bed and slept until ten the next morning. Actually, Caitlyn woke up an hour before Kyle. She was showered, dressed, and downstairs eating breakfast with Aunt Aimee when Kyle finally got up.
