"Alison, do you have any idea where Danny is? It's almost two in the morning," Marjorie Henderson asks her daughter anxiously as the teenager enters the spacious kitchen, just getting home from a date.

"I thought he was at Bobby's," Alison answers, seeing the worried look on her mother's face. She's relieved seeing her mother is preoccupied with where her younger brother is rather than the fact that she broke curfew. She hopes her mother doesn't notice her blouse is buttoned incorrectly, or that she is wearing a shorter mini-skirt than the one she left the house with hours ago.

It is easy to see the two are mother and daughter. Both are tall, leggy, and naturally blonde. From a distance they appear thin, but as one approaches them, their beautifully proportioned curves become evident. High cheekbones, delicate noses, and large, blue eyes that always make men and boys take a longing, second look at their faces. Both have long hair and very fair skin.

"I called Jackie and she thought Bobby was with Danny," Marjorie answers, pacing on the mahogany kitchen floor, wearing her soft, plush housecoat. She frowns. "I'm about ready to call the police," she says, brushing a lock of blonde hair out of her face that has fallen from her hair done loosely in a bun. For a fraction of a second she wishes her cheating bastard of her ex-husband attorney were there-but only for a fraction of a second.

"Maybe he's with-" Alison begins and then is cut off by the sound of the mudroom door slamming open.

"Danny!?" Marjorie calls anxiously, starting to move toward the mudroom as Danny quickly enters the kitchen, looking around as if he is in a daze. He leans against the island counter and looks at his mother and sister. The teenage boy is shorter than Marjorie and Alison, with short, curly red hair. Even for his young age he is built powerfully stocky, like his father. "Where were you?!" she demands tensely.

Alison notices his black, Death Metal T-shirt is on backwards, but she doesn't say anything as her mother hugs her brother tightly, deeply grateful that he is home. She sits down on one of the high-backed kitchen chairs on the other side of the island counter to watch her mother grilling her younger brother for entertainment. "What day is it?" Danny asks, confused.

"Early Saturday morning," Marjorie answers, studying his eyes to see if he may be on something. "Where were you exactly?" she asks, regaining her composure.

"Where's Bobby?" Danny asks, his eyes widening as if remembering something.

The cordless phone rings. Marjorie grabs it quickly. "Hi, Jackie," she answers intuitively and pauses. "Thank, God! Yes, Danny just got home, too. I'm in the process of finding out where he was tonight as I'm sure you're doing right now with Bobby. I'll call you tomorrow. Good night."

Marjorie hangs up and takes a deep, calming breath, then turns and looks at Danny wearily. "Danny. Please tell me where you were tonight," she says very calmly, moving over to him at the island counter.

Danny frowns, looking at his mother, straining to remember. "We-We went down to the Mill Road about nine on our bikes ... then Bobby noticed a-a light coming from somewhere, y'know, in Shaefer's woods and..." he pauses and looks confused.

Marjorie knows her son. He is telling the truth. "Danny, why is your shirt on backwards?" she forces herself to ask calmly, trying not to think about America's Most Wanted.

"Oh, yeah," Danny continues. "Bobby thought it would be cool if we went to spy on who was in Shaefer's woods-you know how pissed that old farmer gets about his woods ... and then we started to sneak through the trees and..." he stops, frowning, trying to recall.

Alison sees Marjorie believes Danny is telling the truth as she finds herself starting to believe it as well, which is unusual.

"And then what happened?" Marjorie asks softly.

"And then ... there was this ... really bright light ... and-" Danny stops. He looks at his mother strangely as if seeing her for the first time and stands straight, his arms hanging at his sides, looking at her.

Marjorie frowns slightly, staring into Danny's eyes, feeling as if it is not just her son looking at her, but someone else.

"-and then we couldn't move," he continues as if in a post-hypnotic state. "We were taken aboard a ship like a ball of light and they did stuff to us and told us things."

Alison feels frightened, sensing her brother is telling the truth. "What did they look like?" she blurts out.

"They kinda' looked like us, except they were small with really big dark eyes," Danny answers emotionlessly.

"What did they say and do to you?" Marjorie forces herself to act calmly, but finds her stomach muscles tensing.

"They told us that our planet had been invaded by beings that wanted to use our genetic material for their own purposes, but that they had come to claim us as their own resource," Danny answers without emotion. "And that we had been selected to participate in their genetic harvesting. They said they would direct me, Bobby, and others, and that all human parties involved would enjoy participating in the harvest and that no one would be physically injured in the process."

Holy shit!" Alison exclaims softly, looking at her mother. "Danny doesn't normally talk like this," she comments, her eyes wide with alarm. "What if he's possessed, or something?!" she asks.

Marjorie shakes her head at Alison, indicating for her to be quiet. "What did they do to you and Bobby?" she asks, her voice grave with concern. Her imagination races ahead with possible police reports and visits to psychiatrists.

Danny smiles slightly, his eyes widening as he stares intensely at his mother. "They put implants in us," he answers softly. "I know what it is I'm s'posed to do," he says, his smile broadening.

Marjorie can clearly see the pupils dilating in Danny's eyes as she physically feels not only his eyes boring into hers, but his mind. It's not just his mind, she realizes as she finds herself unable to move or to break her gaze away from his. Some one, or some thing, is inside him and is invading her mind...

Alison watched her mother and brother staring fixedly at each other, unblinking. She sees Danny smiling as Marjorie frowns slightly, showing signs of distress. "Stop it, you guys," she says. "You're starting to freak me out!"

Marjorie resists, but experiences perverse thoughts and feelings that are alien to her nature even as her body betrays her will as she feels her breasts and nipples hardening, her vaginal tunnel secreting lubricating fluids.

"Danny! Stop it!" Alison says, seeing clearly it is a one-sided battle that her mother is losing. Danny's smile remains fixed as Marjorie's face flushes and her frown increases. Her jaw is clenched tight as she starts to shiver slightly. "Danny! What the hell are you doing to Mom?!" she demands, thinking of pushing one of them away from the other, but Danny looks at her as if sensing what she is thinking and she remains seated, frightened by the power of the alien entity looking at her through her brother's eyes.

As Danny looks at Alison, Marjorie feels the attack on her mental self-control easing, but returns even more intensely as Danny again locks his gaze into hers. Her mind, and therefore her body, are being bombarded with incestuous lust for her own son that is not coming from within her, but the alien is thrusting the obscene desires into her until she can no longer resist. She realizes that soon she will no longer want to as she finds her normal maternal restraint being consumed by the hellish flames of forbidden desires.

Alison realizes she is watching a battle of wills that will have serious, unforeseen consequences if her mother fails. She watches fearful, yet fascinated as her mother's face flushes and she starts to grimace as if trying not to smile. Her blue eyes widen as she begins breathing hard through her slender nose. Her stare intensifies at Danny as slowly her full lips form into a smile.

"Mom?..." Alison asks quietly as she watches Marjorie smiling salaciously at Danny, staring at him with a wild look in her eyes. Alison does not know she is watching the last of her mother's moral restraint vaporizing as she is now consumed by incestuous lust for her younger brother. Marjorie's mouth is open and she is running her tongue over her lips sensuously as she begins panting through her open mouth.

Alison watches in fascination and horror as her mother and brother move their lust flushed faces close enough so that they can stare heatedly into each other's eyes as their tongues lick together sloppily loud. "What the hell are you guys doing?!" she asks in shock as she watches Danny's hands pulling open their mother's plush robe, kneading and fondling her firm, heavy breasts. She cannot see her brother's waistline from where she is sitting at the high island counter, but she can see her mother's arm movements and hear her unsnap, and zip open Danny's jeans.

"Oh, yeah!" Marjorie exclaims huskily as she hauls out her young, teenage son's unnaturally large, bloated shaft. She presses her mouth over Danny's as they embrace heatedly, their hands and fingers feeling and squeezing over each other's forbidden places.

"Stop it! What the hell is wrong with you two?!" Alison swears loudly as she can tell by their arm movements that her mother is jacking off her brother as he is clearly finger fucking her pussy. They both ignore her completely as they continue kissing and stimulating each other frantically as they pant and moan loudly into each other's mouth.

"Stop this twisted shit right now!" Alison cries out as she walks around the counter. "Oh, my God!" she gasps, her mouth gaping open in shock at the length and girth of her brother's cock. She has inadvertently seen him naked before and knows he is pretty well hung for his age, but what her mother is gripping and tugging on is not naturally his. This monster is well over a foot long with a girth like a stick of summer sausage. Alison gasps as his cock appears to twist in her mother's hand, the swollen cockhead appearing to look right at her as if seeing her with eyes. A stream of semen jets out of the little cock slit and lands right into her open mouth, sliding smoothly down her throat.
