The following morning at breakfast Rachel was silent as she ate her breakfast.
"Are you all right, Sis?" Susan asked anxiously. She remembered Rachel being taken by her rider the day before, crying out as Marion held her in her arms while Ryan implanted her master on her back.
Rachel nodded without saying a word.
"What does it feel like, the thing... on you back?"
Rachel made a face. "I don't want to talk about it." In fact her rider had been stimulating her all night, in preparation for her first training session. She woke up hot and sweaty with her hands between her legs, eager for release but knowing exactly how and where she was going to get it.
"Here you are, sweetie, I made pancakes, your favorite," said Marion, setting a platter down by her eldest daughter.
Rachel stared at her mother but said nothing. Slowly she started eating the pancakes.
"Don't be so glum, dear. You'll feel better once Ryan starts your training."
"Training?" said Susan. "What does that mean, Mother? What is Ryan going to do to her?"
"Ryan is going to make love to your sister, dear," said Marion, smiling broadly.
"Make love to her? Again?" Susan asked.
"It's all part of her training," said Marion.
Paul came into the kitchen. "Good morning, dear." They kissed briefly, though Paul's face looked wooden.
"Has Rachel begun her training yet?" Paul asked.
"Not yet," said Marion. "I thought she should have a healthy breakfast first."
"I want her training to begin first thing after breakfast," said Paul.
"Of course," said Marion, bowing her head.
Paul looked at Rachel. "Your brother is going to train you. You are to do everything he says."
Rachel looked from her father's expressionless face to her mother's concerned one. "I... I understand, Dad."
***********
Rachel was not exactly excited to participate in her first training. Like Ryan, she was proving to be more than a little reluctant even though she now wore an immature rider. Ryan came into her bedroom wearing only a bathrobe. Rachel knew what that meant.
"Are you ready to begin, Sis?" he asked.
"Do we... do we really have to?" Rachel asked, still hoping there was a way out of this. She realized she wasn't really talking to her brother. She was talking to her brother plus... something else.
"Of course," said Ryan.
"But...." Her voice trailed off.
"Didn't you enjoy when we made love for the first time?"
"I... yes...." She blushed. The experience had been her best ever, although her sexual experiences had been quite limited before this. But she knew having sex with her brother was wrong. She just knew it! "Please don't make me do this," she whispered.
Ryan cocked his head as if he was listening to something she couldn't hear. Then his facial expression abruptly changed. "All right, Sis. My master tells me you don't have to perform if you don't want to, at least not this time. All my master wants right now is to see your rider. Is that all right?"
Rachel considered and nodded. She moved to take off her shirt. She couldn't see her rider right now but knew what Ryan would see. She had stared in the mirror at the small pulsating mass between her shoulder blades long enough. She had an alien creature on her body, and slowly but surely it was
growing
.
Ryan turned her so her rider was facing him. He started to gently touch it with his finger. Rachel gasped.
"You like that, Sis?"
Rachel nodded. Every time Ryan touched her rider, she felt sexually stimulated. In moments she felt an urgent need burning between her legs.
"Why don't you take off the rest of your clothes, Sis?"
"Why?" Rachel asked.
"My master wants to see you nude."
His master.
The thing on his back. Rachel nodded thickly and reached for her pants. She pulled them off so she was only wearing her bra and panties. She saw Ryan looking at her expectantly. She felt her rider pulsating on her back and its tendrils in her mind. They couldn't control her, not yet, but they could influence her.
Rachel hesitantly unstrapped her bra. She hesitated at her panties. Should she take it off?
Ryan saw her sister blinking, and cocking her head.
"What is it, Sis?"
"My... rider. It wants me to take off my panties."
"And so?" Ryan asked.
Rachel paused, rocking slightly. "I... I must obey."
Then she started to remove her panties.
Yes! Rachel was beginning to obey her rider!
Ryan smiled as her sister obediently disrobed. Even in its weaker, immature state, her rider was beginning to take control of her. And then Ryan took off his bathrobe.
"What are you doing?" Rachel asked, alarmed and excited to see her brother naked. He said he wanted to see her nude; why did he need to
be
naked as well?
Ryan gave a manly grin and spoke in a deep, almost unnatural voice. "I am the male, and you are the female. It's the most natural thing in the world." He sat down by her. She felt the heat of his thigh against hers.
He had tricked her!
Or, a little voice told her,
had she let herself be tricked
?
She felt his lips pressed against hers, and responded.
"You like?"
Rachel nodded dumbly.
Ryan smiled and together brother and sister started doing the most natural thing in the world. As Ryan kissed her and touched her and pleased her, Rachel felt herself burning with desire. It was her rider doing that, she told herself. It was all her rider. And yet, as she looked at her brother's large penis, she realized it was something more, as well.
Ryan smiled as if he could read her mind. He gently pulled her down onto the bed, and Rachel gave in to the inevitable.
**********
Susan peeked through the open crack in the doorway into Rachel's bedroom. Mom said that Rachel was being
trained
. But it was like no training Susan had ever seen. Ryan and Rachel were totally nude in bed together, having sex, apparently. Ryan was lying on his back while Rachel, squatting over his midsection, bounced up and down while Ryan grabbed her hips. Her small breasts bounced up and down and her ribs were more apparent than ever on her skinny frame as she made love to her brother, if indeed that was what she was doing. As Rachel bounced up and down, they spoke to each other.
"You want to be controlled. You want to be controlled," said Ryan.
Susan jumped as she felt a hand on her shoulder behind her as she spied on her brother and sister.
"It's just me, dear," Marion smiled at Susan. "Are you curious to see how your sister is doing? I am too."
"What is he doing to her?" Susan asked as she saw Rachel, with a vacant stare, say, "I want to be controlled," even as she continued to bounce up and down.
"Ryan is helping your sister's rider to grow, and teaching her what it means to be a fully functioning female in the service of the Hive," said Marion.
"Mom, you say that like it's a good thing," said Susan.
Marion put an arm around her youngest one. "Come dear, let's talk. Just you and me."
********
Marion and her youngest were bonding over tea as a mother and daughter do... but with a difference.
"Eduardo's penis felt so good inside me," she said, as recounted her experience with him.
"Mom, how can you sit there and talk about how you cheated on Dad and had sex with a complete stranger?" Susan asked.
"You make it sound like such a horrible thing," said Marion, looking into her coffee cup.
"It is horrible," said Susan firmly. "You betrayed Dad. How could you sleep with another man?"
"Truthfully, I was terrified, my first time," said Marion, smiling wistfully. "The first time I was with a man other than your father, I mean. Having a new man inside of me. Another man's penis. Another man's cum." She smiled again at Susan, and touched her hand. "But Eduardo was so gentle, so loving, just like Ryan was with your sister yesterday. He helped me, Susan." She squeezed gently.
"How... how did he help you, Mom?" Susan asked. When Marion was fully dressed like this, Susan could no longer easily see the creature on her back. She could fool herself into thinking that her mother was back to normal... if she didn't look too closely. Now that everyone had joined the Hive in the family, except for Susan, and there were no longer any secrets to hide, Marion had started wearing tight blouses around the house. When she turned away, Susan could see her rider quite clearly through her shirt. It was big and heavy and meaty, going down half her back. When it pulsated, her shirt actually moved with it. Susan wanted to believe she was talking to her mother, but she knew in reality that she was talking to Marion's rider, or whatever Marion's rider had turned her into.
Marion's shirts were tight in the front as well as the back now, clearly showing off the shape of her large, heavy breasts. The days of baggy sweaters were long gone. She wore a sheer shirt now which shamelessly revealed the shape and contours of her breasts. Her nipples were hard and firm and pointing out through the stretched fabric, something that would have been inconceivable for Marion to display merely weeks ago.
She seemed to prefer tight pants too, ones that showed every stress line between her legs as well as her well muscled thighs. She wore heavy makeup, eye shadow and rouge and lipstick, which made her look highly sexualized. Even her eyes were different. They seemed to glow in a way that made Susan deeply disturbed.
And yet some of what her mother was must remain. Marion had fought tooth and nail to keep Susan out of the Hive, even as she went off on the great virtues of being part of the Hive, a glaring contradiction. Somewhere inside of Marion must still be a part of her that the Hive hadn't conquered. Susan hoped, perhaps with futility, to reach that part of her mother.
Marion smiled at her with that new glow in her eyes. "Eduardo taught me that love is universal. That I am just a vagina, made to give and receive pleasure from men. He taught me that my rider is my very best friend. I have come to love it so much, especially as it's taken greater control of my mind-"
This was too much for Susan. "Mother, do you hear what you're saying? You're telling me how happy you are that your mind has been taken over!"
"Yes, dear," said Marion calmly, as she stirred her tea.
