Susan was sobbing in her bedroom when there was a tap at the door. She ignored it. The tapping was louder.
"Go away!" she cried.
Ryan slipped into the room, closing the door behind him.
"What do you want?" she asked.
He came over and gave her a hug. "You've been crying," said Ryan.
"Have I?" Susan asked, wiping away the tears. "I'm all alone now."
"No you're not, Sis! If you join the Hive, we can all be together!"
"Ryan, I don't want to join the Hive!" said Susan.
"I saw the way you were looking at me when I was training Rachel. When I was with Mom in the living room. You want it, don't you?"
"No," said Susan, shaking her head.
"Yes, you do," said Ryan. He reached out and kissed her.
Susan didn't even resist, not even a little. She melted in his arms. All the stress came pouring out of her. All the unrelieved stimulation had done their dirty work. Her worm had prevented Susan from masturbating herself to gain relief. It would only allow her to receive pleasure from others. Susan had been kept on the edge for days. She hugged and kissed Ryan tightly, half out of her mind with need.
"I can do it," said Ryan feverishly. "I can do it so you won't feel a thing."
"No!" Susan shook her head. "I don't want a rider. I just... I just want to fool around a bit. But no rider, all right?"
"All right," said Ryan reluctantly.
Susan and Ryan hugged and kissed some more.
"I feel so lonely, Ryan. I'm all alone," she whispered between kisses. She felt Ryan's warm chest pressed against her titties.
"No you're not," he said, kissing her fiercely. "We all still love you, me, Mom, Rachel and Dad."
"Dad just wants to fuck me," said Susan, as she kissed him back.
"He's not the only one," said Ryan, in a deep, manly voice that excited Susan terribly. He put his hands under her shirt, and started to squeeze her titties.
"Oh... Ryan... I don't know," said Susan. She felt terribly conflicted. She was extremely aroused, her worm saw to that, but this was her brother.
"Shhhh, it's going to be all right," he said. His voice was so reassuring, so manly, that Susan let him slip her shirt over her head. She even left him unsnap her bra.
"Oh, Ryan, I don't know about this," she said again as her breasts came free. She resisted the urge to cover them with her hands.
"I do," said Ryan firmly. He looked at his sister's firm melons. They were much larger than a typical 18 year old's, certainly much larger than her older sister's. They were almost as large as her mother's, but firmer, with barely a hint of sag.
And then he reached down and took one of her firm breasts in his hand and squeezed it, ever so gently. "They're so
beautiful
," he said with awe.
"They... they are?" Susan had seen the way men stared at her breasts. She knew she was attractive. But to hear her brother saying it while he was fondling one of her naked breasts moved things into a whole new territory.
"Uh huh," said Ryan, in a deep manly voice. And before Susan could decide whether she really wanted her brother, her dear brother, fondling her breasts, he put his lips over one of her teats and started to suck.
"Ahhhhh!" Susan was immediately rendered helpless. The worm in her clit saw to that. Each suck was amplified tenfold in her clitoris as the alien worm amplified her pleasure. Susan realized that Ryan was pleasuring her the exact same way she had seen him pleasuring their mother, and somehow the thought of it was all the more arousing.
"Ryan!" she gasped, her eyes closed, her hands gripping handfuls of bedding, as her dear, dear brother sucked her off. After all she had been through, after all she had seen, she needed physical release more than anything.
Ryan, seeing Susan's resistance ebbing, took a quick moment to take off his clothes. When his penis came into view, it was already partially erect, framed by the same dark pubic curls as his mother's. The tip had a glowing green symbol on it.
It had just been inside Mom. And now he's going to put it into me.
Susan's ambivalence rose as she let Ryan take off her skirt. It went clattering to the ground. He started to pull on her panties but she restrained him. "No, Ryan."
"No?" he said, sounding like the frustrated teenager he was. A frustrated teenager with a rider pulsing on his back. Ryan heard his rider whisper something inaudibly inside his head, and nodded. He started to rub the head of his penis against the soft, shiny material of Susan's panties.
The effect was electric.
"Uh... uh.... uh, uh, uh," said Susan.
"You like this, Sis?" Ryan grinned.
"Uh.... yeah," said Susan, with a pained expression.
Ryan gave a wolfish smile and pulled again on her panties. This time Susan didn't resist.
Susan had a still growing field of soft, curly blonde pubic hair, only a shade darker than the top of her head. Ryan looked at her thick labial lips and felt an ache deep in his balls.
"Sis, you're so beautiful!" he whispered.
"I am?" Susan said, feeling a secret thrill that had nothing to do with her worm.
"Yeah," said Ryan. He leaned forward and pressed the head of his penis against her slit.
No!
"No," Susan cried.
"No?" said Ryan, sounding confused and frustrated.
"I'm a virgin," said Susan. "It's bad enough doing what we're doing. I don't want my virginity taken by my own brother!"
"But-"
"Just use it to rub my clit," said Susan. There was a pleading in her eyes. "Please?"
Ryan nodded reluctantly. He gently peeled back Susan's labia to see her clitoris. He saw the worm nestled tightly around the base of it. He wondered how much of Susan's arousal was his own doing and how much was the Hive's. Not that it really mattered. He started to rub the head of his penis against her clit.
Susan groaned with sheer pleasure. The worm had made her clit incredibly sensitive. As her brother pleasured her, she looked down at his shaft. The same shaft she had seen coursing inside of Rachel and her mother. He looked so manly, so sexy as he pleasured her. Her eyes turned to the mirror behind the bed. She could see his rider, between his shoulder blades, pulsating. What was it doing to him? Was it Ryan making love to her right now... or his rider?
"Do you like this, Sis?"
"Oh yes, Ryan," Susan said, groaning with pleasure. Despite the horror of knowing her brother was under alien control, it felt too good to deny.
And yet, part of her mind still resisted.
What am I doing?
Susan thought, as her older brother rubbed his genitals against hers. A week ago this would have been unthinkable. But for Susan, this physicality was essential to maintain her sanity. Her worm had been stimulating her unmercifully, especially around the sight of Ryan making love to Rachel and her mother.
"You're so sexy, Sis," said Ryan. "Even more than Rach."
"I am?" said Susan.
"Yes," said Ryan, with deep and utter conviction, as he grounded his penis against her clitoris. "I can't wait to put it inside you."
"No, Ryan," Susan whispered. But she felt her resistance ebbing.
"I will have you," said Ryan. "We all will. Once you join us."
Once you join us.
A chill went down Susan's back.
And then suddenly Susan saw it, in the mirror. His rider was starting to bubble on his back. All the energy that Ryan was exerting to stimulate her was also causing his rider to reproduce.
"No, Ryan. Don't let it split," Susan said.
Ryan ignored her, and continued to gasp as he rubbed the head of his organ against her clit. His rider started to get dangerously large.
"No Ryan!" Susan yelled. She slapped him in the face.
"Hey!" said Ryan. Immediately the bubbling of his rider reduced markedly.
"I don't want that thing splitting," said Susan.
"I can't help it. When I get excited, it does."
Susan's eyes narrowed. She still desperately needed to come. "Then help me come without getting too excited."
Ryan gave her a cynical look, but slowly nodded. He substituted his hand for his penis, rubbing Susan's worm engorged clit as she instructed him. "Slower... a little harder... more circular", she said, as she put her hand over his. "Yes, that's it! That's it Ryan!" She smiled up at him, lovingly, without reservation. Her own brother was giving her sexual pleasure, and Susan was enjoying every minute of it.
"Now faster, Ryan, faster!" Susan cried. And as Ryan's hand moved faster, Susan gasped and cried out, her eyes wide. Then she collapsed backwards on the bed.
They lay in each other's arms for a long moment. Susan realized who she was lying with and what they just did.
"What did we just do?" Susan asked. She had just had sex, sort of, with her very own brother!
Ryan grinned at her. Susan felt a hardness against her belly. She was acutely aware that his organ was still erect. "Are you going to be all right?" she said subtly.
"Yeah, I guess," said Ryan. "Mom or Rachel can help me out, I guess." He saw Susan blush. "But eventually you'll want to do me yourself. I just know you will."
"Maybe," said Susan, looking away.
"Are you sure you don't want to join the Hive, sis?"
"I'm sure," said Susan, with a firmness she didn't feel, as she pushed him back slightly. She looked at his body with lust in her eyes. "Listen, don't tell Mom about this, all right? If she finds out, she'll only put more pressure on me to join the Hive."
"Sooner or later, you will," said Ryan. "Sooner or later, you'll want to."
**********
Later that day, Marion was summoned to Chloe's house to witness "something wonderful." She had little trouble guessing what that was.
Chloe was giving birth to Paul's baby.
When she got there, she found Chloe nude on the back porch, her belly bloated and her legs spread wide. Paul held her hand and looked concerned and proud. The birthing had already begun.
