This will make more sense if you read the earlier parts. Don't worry, they're fun, action packed, and build the tension. Read them first! Also, all characters in sexual situations are 18 years or older. Enjoy.
Axcix had a hard time keeping track of subjects when they traveled too far away. This is why she spent a good while piecing together various broken strands of data. When she finished running her algorithm and got most of the puzzle together, she hissed and gurgled at the bottom of the lake. It was good that she dwelled in the dark green muck, because the round alien ball wanted to hide her shame.
There weren't many constraints put on her by the makers. They made her to think on her own. The makers wanted her to evolve and adjust to her new planet. There was one cardinal rule, however, localize your experiment. Otherwise, she could ruin other localized experiments. Or worse, she could alter the entire species before it was time.
Cursing to herself, Axcix modified her experiment. There were only a few outside her region infected so far. She would have her subjects bring them back to the local habitat. As for the lactation, she should be able to limit the effective radius. She worked furiously to make the modifications and sent out a new wave of nanites through the water.

The windows were still dark when Linda woke with a start and sat up in bed. Poor William snored happily next to her. How could he be so unaware of what his wife had been up to? By the end of Saturday afternoon, she had begged her own son to give her a baby and quivered in ecstasy when he planted his seed inside her. She had fed a young woman from her miraculously dripping breasts. Linda climbed out of bed.
Little Ms. Olivia Green had been corrupted. And sweet Linda, the once faithful housewife, had done the corrupting. Nothing made sense anymore. Linda quietly walked to her dressing room and chose one of her new dresses. She slipped out of her nightgown and into the dress. She snuck out of her room, not yet knowing where she was going.
The clock on the mantle downstairs was the only sound in the house as it kept its steady beat. The car keys, Linda needed the car keys. She picked them up off the hall table, grabbed her purse, and walked out to the car. She got in and started the engine.
Thoughts of the big city floated into her head. She looked at the dash clock. It was three in the morning. She pulled out of the driveway. She needed to find that mousy salesgirl and bring her back to Portsmith. With any luck, Linda could get there, find Olivia, and get home before anyone knew she was gone.

Patrick woke up very early on Sunday from a bad dream about monsters from outer space. The stars were still out outside his window. Sticky with sweat, he pulled himself out of bed to use the washroom. He stopped in the hall when he noticed that Sally's door was closed. Their parents kept both his sisters' rooms the same as when they left, so whenever they came home they had a place to stay. Patrick pushed his hand through his messy, black hair. It was damp with sweat. He took a deep breath and stared at the door.
Did Sally and Jack have sex in there last night? The thought of one of the Lannit children having sex under Susy and Fred's roof seemed pretty far out there, but they were married. So ...
It was a mistake to think about his sister and sex. Patrick still needed to pee, but his dick transitioned into full morning wood mode. Indecisive, Patrick stood in the hall. Should he still try the washroom? Should he wait until later? Maybe tug it back down?
Sally's door opened and out stepped the blurry shadow of his sister. Patrick hadn't put his glasses on, but he could tell it was her. She closed the door after her and gave a start when she saw Patrick standing in the hall.
"Wow, super creepy, Pat." Sally brushed her red hair out her eyes and looked Patrick up and down. "What are you doing?" Her eyes paused when her gaze got to the enormous tent in his flannel pajamas. "Real mature, dummy. Just waiting out here to freak me out with a fake boner? How'd you even know I'd get up?"
"What?" Patrick tried to focus his eyes. He could tell she was wearing something bluish, probably some silk pajamas. He couldn't see her expression, but it was a pretty good guess that her freckled face was frowning. "I'm going to the washroom."
"Good for you. I woke up really hungry. I'm getting a snack." Sally stepped closer to her brother. Something was different about him. He still looked dopey as ever. She inhaled deeply. He smelled strange, like something ancient and secret. Like the dark side of the moon. "You know, I've missed you, Pat." Her tone changed. "Come give your big sister a hug." She opened her arms to him in the cold, dark hall.
"Um ... okay." Patrick stepped up to her and gave her a weak, sideways hug. He didn't want to press his dick on her.
"Hug me like you mean it, dummy." Sally reached around his back and pulled him in. Warmth and tingling sensations spread through her vagina. It was odd timing, but she ignored it. Something poked at her belly. "And lose that stupid fake boner." Sally reached down between them and placed her left hand into Patrick's pajama bottoms. She gripped the monstrous thing and tried to pull it free. Her eyes widened in the dark. The thing was attached. "Is that real?" She whispered. "Is that your ... dick?" She pressed her finger into the veiny, spongy flesh.
"Yeah." Patrick felt the cold metal of her wedding ring on his dick. It contrasted with the warmth of her hand. "Let go." Patrick's chest was scrunched against her boobs, her right hand holding the back of his pajamas tightly.
"Ever had one of these?" Sally moved her hand slowly along the shaft, up and down. "I bet not. You're shy with girls. Is Big Sister your first handy?" She inhaled deeply. What a wonderful smell.
"Don't do that, Sally." Patrick had never had a girl's hand on his dick before, she was right. And it felt so good he almost forgot himself. "It's not you, there's something going on in town. There's a mystery."
"Life has a way of surprising you." Sally wasn't listening to him. Her hand sped up. She relished the way the foreskin slid over the wide head. "Why'd you keep your dick hidden all this time?"
"Jack's right in there. In your room." Patrick tried to gently pry himself away. He didn't want to cause a ruckus, but he needed to get out of her clutches before he reached the point of no return. "What if he comes out?"
"He would be very unhappy, dummy." Sally wanted nothing more than to bring Patrick to completion. "So, let's be quick."
"Think about what ... ah ... you're doing." Patrick's legs shook.
"You ..." Sally bit his left ear playfully and nibbled on his earlobe. "... should be grateful. There's not many big sisters that would do this for their runty little brothers."
"That's ... oh ... Sally. That's ... my point." Patrick closed his eyes and leaned his head into her shoulder.
"Just cum, dummy." Sally could feel his whole body trembling. She lowered her right hand from his back to his skinny butt and grabbed tightly.
With a series of soft grunts, Patrick came in his pajamas while leaning up against Sally.
To her amazement, shocks of pleasure spread from her left hand as the warm liquid splashed onto her hand, wrist, and arm. "Oooohhhhhhh, Pat." Her pussy clenched and she had her own orgasm. The two of them shook together in the hall as they shared in the ecstasy. When Sally was done, she removed her hand from his pajama bottoms and wiped the cum off on Patrick's top. "Well, I don't know what that was all about, but don't tell Mom and Dad. Okay?"
"Or Jack?" Patrick took a step back from her.
