It was night at the Stevens house. As usual around ten o'clock, Mrs. Stevens sat in bed under the covers reading as her husband lay waiting for sleep beside her. In the room down the corridor, Timothy was on his computer, or reading, or whatever. In the room next to his, his sister Nora slept soundly. Although Timothy was a few years older than her, he was immature in a general sort of way. His parents were always harping on him to get a girlfriend, and Tim, their virgin son, never met their expectations.

Patricia thought about her son. He was well built, fairly tall, with brown hair. Nora, his sister, was slightly less attractive, but was a mature girl for her age, and her blonde hair, sometimes braided into a single tail, hung over the slight curve in her back. Pat liked to buy nice clothes to fit her.
Suddenly she heard a thump coming from somewhere in the house. A quick glance at the clock revealed it to be twelve-thirty. When she got to the hallway, a small moan could be heard. Pat immediately recognised it to be the signal of her son's furvent masturbation, something she pretended to ignore as she found towels, tissues, etc., covered with semen. She pitied her son's frustration, and coming to her room, she pushed her husband gently into wakefulness.

"Tom, Tom," she said.

"Wha... ?" he mumbled in tired half sleep.

"Tim's at it again. He's always pulling that damn peter of his without anywhere to spunk. It's sad," she said with an abstract thoughtful expression.

Her husband wakened a little. "I don't see the need for him to do anything else."

"Tom, you' don't see the point. I'm sick of seeing toilet paper and whatnot that he puts over his penis to catch the fluid. I'm gonna do something about it." And with that, she left the room. Her husband laughed and fell back to sleep.

Tom held his fingers around his dick and pumped. He thought about the girls he had just seen on the internet. Suddenly, the door opened and his mother peeked hesitantly around it watching him. "Mom!" he said with anger. "What are you doing here?"

She came into the room and he saw that she held his sister in her arms, carrying her to his bed where he reclined, dick comfortably in hand, half at attention.

"I have something better for you to cum into," his mom said chirpily. Nora was somewhat asleep, but she opened her eyes groggily, and her face twisted into pained surprise. "What's going on here!?" she cried.

"Nora..." her mom calmed her. "We're just doing something that needs to be done for your brother, who's past puberty now and needs to relieve his genitals. When you're older you'll understand. Maybe if he makes a baby we'll raise it together, and get our family properly started. Anyway," she stopped talking, her hands firmly held on each side of Nora's slim waist, her strong mature arms taking her up over Tim's wang.

"Nora!" Tim said in disbelief. "Mom, this is just insane. But thanks, I guess." He waited now, in eager expectation of the coming action.

Finally, his mom reached out and put her hand under Nora's night slip and rubbed her pussy efficiently, a slopping noise coming to show her daughter's readiness for intercourse. Then, her hand wet with Nora's juice, she grasped her son's meat and pulled it into arousal. Once it was mostly hard, the big moment came. She positioned Nora perfectly over Tim's cock, and strongly pushed the body of the girl onto her virgin brother. His penis slipped into a delicious, cute little girl, Tim sighed contentedly, enjoying the sensation of having himself wrapped with moist flesh. His mother continued to lift up and push down her young daughter to speed Tim's pleasure. All three were engaged in integrated sex, for the sole purpose of having an eighteen year old chronic masturbator release himself happily. A pretty teenage girl, with beautiful skin, her legs cradled around her brother on his bed, being helped to ride on his piston. She did not dislike the orgasmic pleasure, of course, but she resented the ease with which she was being used as a mere aid to masturbation, like a sock. Still, she said nothing, because she knew her family's rule of equal chores.

Eventually, Timothy moaned loudly, and held his sister down by the legs, feeling the cum spurt silently into her young body. Nora had a vague look of refusal on her face, bitterly contemplating the possibility of becoming impregnated as a result of her mother's forced solution to her brother's problem. Oh, well. A baby to raise might not be the worst of things.

Six months later, Patricia notice a moderate bump on her daughter's belly. "Nora," she said with praise in her voice. "You've managed to conceive. I'm so proud of you. Soon we'll have a daughter or son to continue our wonderful tradition. Thank you."

The Stevens lived happily on, ever hasty to meet the demands of nature, to spread the seed and to keep one's legacy pure and plentiful.
