Chapter Four - Shaping Up

When David and his sister returned to the living room, Sylvia was sitting, reading quietly. "David," she asked, "when are we going to get our new bodies?"

"I don't know, Sylvia." He looked at the ceiling, "AI, when are the med-tubes going to be free for changes to concubines?"

"Some tubes are available currently, sir. Changes can be scheduled for any time during the remainder of the journey, subject to tube availability and concubine training requirements. All initial checks and necessary medical work on sponsors have been completed."

"So once we've decided on the changes we want, they can be done pretty much straight away?" David confirmed.

"Affirmative, sir."

"So, Sylvia," David said, "since you asked, you can go first. AI, show us a hologram of Sylvia as she is at the moment." The AI responded with a life size display of a naked Sylvia in the middle of the room. She jumped a little when it first appeared; she hadn't realized that the AI could show something like that. The hologram was rotating slowly, so all three of them could see every side of it.

"Keep the original there please, AI, and show us a second copy for the modifications."

The AI showed another hologram of Sylvia, next to the first.

"Well, what would you like to look like, Sylvia?"

"Umm..., well, I'm not really sure. It's all up to you really, isn't it, David?"

"It's your body, Sylvia, and I'd rather have you happy with the way you look. I think that will be better for all of us in the long term." Remembering what the ensign had said about altering mothers, he continued, "There was some advice they gave us. We shouldn't change you so much that we upset Pat and Mary. They need to be able to recognize you after you come out of the tube."

"That seems sensible," Sylvia agreed. "AI, can you roll me back to age twenty one, before Pat was born, without the jelly-belly."

The second hologram changed to show a younger, slimmer, Sylvia. The pooch in her stomach was gone and her breasts had shrunk a little, standing higher on her chest. Her hips and thighs were carrying less fat, though they weren't as slim as Rachel's.

"Oh my! I can see why Des fancied me." Thinking of her husband, left behind on Earth, Sylvia started to cry quietly. Rachel immediately got up from where she was sitting and moved over to comfort the older woman.

David thought it would be better if he left the two of them to it for the moment, it seemed to be women's business. He examined the changed display. He knew that Rachel would want to grow up, and he wanted to keep Sylvia as his senior concubine, so he had the AI advance her to twenty five, but without the effects of her pregnancies. He liked her breasts as they currently were, so he compromised by having them half-way between the younger version and their current size, though still sitting higher. He did the same with her hips, changing them to half-way between. He liked the contrast between Rachel's narrower shape and Sylvia's more rounded curves. Those changes also had the advantage of producing a new look closer to her current appearance, and so less likely to cause problems with Pat or Mary. He took the opportunity to clean up a scar on her knee that looked like it had resulted from a childhood injury.

"I'm sorry about that," Sylvia said, interrupting David's thoughts. "Seeing myself looking young again brought back a lot of memories. I'm all right now." The older woman had collected herself again, though Rachel still had an arm round her for reassurance.

"Not to worry, Sylvia," David told her. He was slightly shocked at her crying. Up to now he had thought that, of the three of them, she was coping the best with the changes in their lives. Perhaps she was actually feeling it more than appeared on the surface?

"You made me look older again," Sylvia complained, looking at the modified hologram.

"I wanted to keep you at about your current age," David explained. "If you look too young then I'd have to keep Rachel looking fourteen and I know she'd hate that."

Rachel was indignant. "Don't you dare David! I want to grow up. I don't want to stay like this forever." His sister was eager to acquire a more feminine figure.

"I suppose it's not too bad," Sylvia said eventually. "I'll probably be spending a lot of the time pregnant anyway, so I'll only look like that between babies."

"That is correct, Concubine Sylvia Harlow," the AI interjected. "You will be returned to this appearance after each pregnancy."

David was getting irritated by the AI's habit of using full names and titles when they weren't necessary. "AI, please call us by just our first names when no other people are present."

"Yes, David," the AI responded.

"What about hair, Sylvia?" David suggested. "No need to shave if you don't want to."

"Good, I hate shaving. No hair please, AI."

As the hologram changed, all three of them burst out laughing. Sylvia buried her face in her hands.

"The Bald Prima Donna!" David exclaimed.

Instantly, Rachel responded, "She always wears her hair in the same style."

Sylvia lifted her head and looked at Rachel, puzzled.

"Ionesco," Rachel told her quietly.

Sylvia was none the wiser, but decided to check on it later. The AI should know what it was all about. Turning to her sponsor, she said, "I hope that doesn't give you any ideas, David."

David did an exaggerated Fu Manchu impersonation, stroking an imaginary moustache, "Now I know how to punish you if you're naughty. You'd better be a good concubine, Sylvia. No more cheekiness, or I'll have you looking like that." Sylvia blushed, while Rachel giggled at the thought.

David took pity on her. "AI, just remove visible hair below Sylvia's neck, leave the hair on her head as it is."

The hologram changed again, and Sylvia relaxed, "That's what I meant. The AI can be much too literal sometimes."

David smiled. She was right about the AI. "While we're on hair, how long do you want it, Sylvia? The AI can fix it so it won't need trimming."

"Can I change it when I want to?"

Again the AI interrupted, "Small changes like that can be done easily with your sponsor's permission."

"You have your answer, Sylvia," David said.

"OK, keep it the length it is for the moment, I only had it done a couple of weeks ago. I can always change it later." By now she knew enough about David to trust him not to be petty about small things, like a new hairstyle.

"Any other changes, Sylvia?"

"Could you take away that mole on my cheek and make my nose a little smaller please. I think it's too big for my face."

David was puzzled, he couldn't see anything wrong with Sylvia's nose. "Your nose looks fine to me as it is, Sylvia."

"Please, David. Only a small reduction."

"If you insist?" Sylvia nodded vehemently in response. "AI, please reduce Sylvia's nose slightly, say five percent. And remove the mole as well."

Sylvia smiled at the result. "Yes, that's a lot better."

David couldn't see any real difference. "That seemed important to you," he asked.

"It was. I was teased about my nose at school. I've always wanted to change it a little. I know it's silly but...." She shrugged with a wry grin.

"If it makes you happier, then it's worth doing. Any other changes you want? I cleaned up the scar on your knee."

"Oh yes, so you did." She paused, considering her new image as it turned in front of her. "No, I don't think there's anything else. Can I have another look at me in the morning please, David? I might think of something overnight."

"Of course. AI, please save that version of Sylvia, and let her see it when she wants tomorrow morning. She can make changes, but I want to OK them before they are implemented."

"Confirmed, David."

David turned to his sister, "Now for you, Rache. Two holograms of Rachel please, AI."

"Can I be twenty please?" Rachel asked. The AI changed the second hologram to show a much more feminine Rachel, with all her curves fully in place. Not as many as Sylvia, but unquestionably more than the current version. She wasn't any taller, having already reached her full height, but her shape had definitely caught up with her height.

"I'd rather you grew up as naturally as possible, Rache," David said. "I want to do the least possible in the tubes, and let the rest develop normally. AI, roll her back to eighteen."

The hologram changed slightly. "That still looks pretty good, Sis."

"I s'pose so." Rachel couldn't see any real difference, but she wasn't going to let her brother know that.

"Back to sixteen, AI."

"Ugh! I'm still a stick insect," Rachel burst out.

"The prettiest stick insect ever I think," her brother told her. At sixteen she was thinner, though still more rounded than currently. The promise of her final shape was definitely there to see.

"Keep the sixteen and show us a fifteen," David ordered.

The two holograms moved further apart, and a third image of Rachel appeared between them. "That's horrible," she said. "It's just like I am now."

"Well, it is less than a year away," he pointed out, "and you have put on some weight. There's more shape to your waist and hips by then."

"Please, David. I don't want to spend years 'til I look nice."

David considered the problem. His sister wanted to grow up quickly, while he wanted her to grow more slowly and naturally. He thought it would be better if her age and her appearance were more in step. Obviously he could impose his will, but he also wanted Rachel to be happy with her look. Then he thought of the way his Marine upgrade was being done, both in the med-tube and more slowly later. Perhaps he could do something similar with Rachel. Silently he questioned the AI, «Can I spread Rachel's changes over time, like with my own enhancements?»

«Yes, David.»

«Could it be over months, rather than a few weeks?»

«Yes, David. It would be better if any changes were completed before she became pregnant, but other than that there are no issues with extending the time taken.»

«I want to wait a bit before her first pregnancy, as I'll have Sylvia going first. I've got six months to get Rachel pregnant, haven't I?»

«Correct, David. Female concubines should be pregnant within six months of being extracted from Earth.»

He turned to his sister, who had begun to look anxious. "Rachel, I think we can compromise. You know that my changes are coming on slowly?"

Rachel nodded, "You mean I'll get mine slowly too?"

"A bit of both. I'll advance you to fifteen in the tube, and then have you grow up to sixteen in the next four months. How would that be?"

"Can't I go straight to sixteen, and then slowly to seventeen or eighteen?" she asked.

"Sorry, Sis, I don't want to speed you up too much. We can think about it again in four months time. You look hot at sweet sixteen." He smiled at her, while Sylvia nodded her agreement. The older woman thought it was sensible for David to allow time for his sister to have her personality catch up with her appearance. A fourteen year old mind in a twenty year old body would be strange.

"What about my boobs? Please can I have bigger boobs, David?"

David knew his sister was worried about her breasts being too small, so he allowed a small boost, "Add six months growth to her breasts on the fifteen year old image please, AI." The image showed a somewhat increased bust. "How about that, Sis?"

Rachel grudgingly accepted her brother's decision. "As long as we can talk about it again in four months."

"Yes, Rache, of course. Now, are there any other things you want done? Hair?"

"Can you take away my armpit hair, but leave the other. I only just got it, and I don't want to lose it yet."

"As she asks, AI," David said. Seeing the result he continued, "Trim back her pubic hair a bit, and tidy up the edges." Turning questioningly to his sister he saw her nod in return. "Anything else, Sis?"

"Can you fix my teeth, AI. Straighten them and whiten them."

"Some straightening can be done, Rachel," the AI told her, "but your third molars are not fully developed yet, so it would be advisable to restrict changes to the front teeth only for the moment."

"Just the front teeth is fine."

The middle hologram stopped rotating and grimaced, showing an even set of white teeth. Sylvia made a mental note to get the AI do her teeth, she hadn't considered having it do that for her. Just as well that Rachel had thought of it.

"Too white," David said, "they look artificial." Tone down the color a bit."

He looked at his sister, who nodded her acceptance, "They did look a bit weird, all perfect white like that." She continued, talking to the AI, "Can you do something about my face, it's all lop-sided."

Three life-size disembodied heads appeared floating in the air in front of them. The AI explained, "All three heads are exactly symmetrical. The left hand head is the left hand side of Rachel's face mirrored to make a whole face. Similarly for the right hand head and the right hand side of her face. The middle head is the average of the left and right sides, also mirrored."

The three of them looked at the heads. David thought that they made his sister look unreal, almost like a robot. Real people's faces weren't that precisely symmetrical to the nearest millimeter.

"They look too perfect," Rachel said. "I prefer the right version, but I don't really want to look like any of them. I'd feel like a Barbie Doll."

"As opposed to a Bratz Doll?" David joked. He was glad she agreed with him about the artificial appearance of the displayed heads. "AI, change the middle head. Add in one third of the left side and two thirds of the right side so it's no longer perfectly symmetrical." He had noticed his sister's preference for the right hand head, so biased the changes that way.

"Ah, that's better," Rachel agreed.

Sylvia did as well, though she kept silent. She made another mental note to try the same thing with her own appearance.

"It looks more like me and it isn't so lop sided," Rachel continued. "Can we try different proportions of left and right?"

After a few minutes experimenting Rachel settled on a new look that she was happy with, and that David was glad to confirm. "You can have another go tomorrow morning, Rache, like Sylvia." His sister nodded her acknowledgement.

When David stood up to go to bed, Rachel was initially both eager and nervous. She ended up disappointed when her brother told her that she would be on first call for babysitting overnight. She would be sleeping on her own, while Sylvia shared his bed again.

While they were both getting ready for bed, Sylvia told David that his sister had been asking questions about sex. "She's worried about anal, and puzzled how some women can deep throat."

"Anal?" David was surprised. "Wherever did she get that from? Dad would never ever have said anything to her about that."

"It was in this morning's concubine training film." Sylvia's Irish accent was coming out with the word 'film'.

"Ah, that explains it then. I've never tried anal, so I can certainly hold off doing it with Rachel. Have you done that, Sylvia?" She blushed and nodded. "Good, you can teach me first." Noticing her mild embarrassment, he moved on to Rachel's second query. "What did Sis want to know about deep throat?"

"She was just surprised that anyone could do it at all. She thought it would make them throw up."

"Concubines get some help from the nanites for that, they reduce your gag reflex. That makes it a lot easier."

"Will I get that with my new body, tomorrow?" she asked.

"No," he told her. "You got it yesterday, at your initial medical check. Want to try it?" Naked, he sat on the edge the bed and spread his legs.

Sylvia knelt in front of David, jacking him lightly. As soon as he started stiffening, she moved in to lick his shaft from balls to tip. When he was ready, she bent forward to take the tip into her mouth, licking round the top, adding her saliva to the pre-cum he was already beginning to produce. She took him into her mouth, letting him penetrate as far as she was used to. Pulling back, she repeated the move a few times to get him well oiled with her saliva. Then she drew a deep breath and gingerly engulfed him further, and further, and further! When her nose reached his pubic hair she pulled back, an expression of surprise on her face, "Bloody hell!"

David grinned down at her as she dove back down onto his cock, eagerly trying out her new skill.

In her small bedroom, Rachel lay awake, thinking. Yesterday, the lieutenant had said she was a sex slave. Back then the idea had frightened her, even terrified her. She was still a bit nervous about the sex part, losing one's virginity was meant to hurt a bit. But the 'stuff' she'd been doing with David was sex as well, and she'd certainly enjoyed what they'd done so far. Perhaps the sex wouldn't all be as bad as her worst fears. And the fact that it would be with David helped. She knew he would do his best to make it good for her.

She thought about the slave part as well. Dad had gone on and on about the proper Biblical role for women. They had to obey their fathers and, once they were married, they had to obey their husbands. Well, concubines had to obey their sponsors, so there wasn't really a lot of difference. Obedience was always required. A husband was meant to love his wife, which didn't necessarily apply to sponsors, but surely applied to some. She could think of a few married couples from church who didn't seem to love each other. David was her brother, so, in her case, she definitely had a sponsor who loved her. Obeying David had, so far, been a lot more enjoyable than obeying Dad. Although he probably didn't realize it, her father had actually been training her to be a good, obedient, Confederacy concubine. That thought amused her; it certainly would have horrified Dad!

She was woken from her sleep by the AI, "Rachel, Mary is awake and crying. She appears to need comforting." Blearily she got out of bed. As she was crossing the main room to the lift, she noticed Mister B. lying face-down on a chair where he'd been left. Thinking that he might help with Mary, she grabbed him and went up to see what the problem was.

Mary was awake and sniffling. Luckily she was doing it reasonably quietly, so she hadn't woken Pat. "I miss my Da," she told Rachel between sniffles.

The teenager couldn't produce Mary's father, but she did have Mister B. "Here, you have a good cuddle with Mister Bozo, Mary. I'll sit here for a bit and things will be better in the morning."

"Can I keep Mister Bozo please, Rachel?"

That shook Rachel. Was she quite ready to give up that much? She knew she was a bit old for toys, and in the final analysis her teddy bear was just a toy. He did represent a lot of her past, but all that past was now back on Earth. She had grown up a lot in the last couple of days; had she outgrown Mister Bozo and all he symbolized? She made her decision, "Yes Mary, you can keep Mister Bozo. But I might want to borrow him back for a little bit when I'm feeling miserable."

"Yes, but only for a little bit."

"That's agreed then, Mary. You can keep him."

"Thank you, Rachel." Mary smiled faintly, hugging the teddy bear to her. Rachel sat on the small bed, comforting the young girl by her presence, as the child drifted back to sleep. Inevitably, Rachel was reminded of the many times she herself had hugged Mister Bozo at night in her bed. It felt right for her to give him up now. She was definitely moving away from her girlhood and into womanhood. Keeping him would be a sign that she still wanted to be a child; not the sort of message she wanted to give to her brother. Not the sort of message she wanted to give to herself.

In the morning, David awoke to an empty bed. He spent a little time, lying there, thinking about the day ahead. Sylvia would be getting her new body today, and he would also set her up to get pregnant soon. She already had the experience, so she could go first, ahead of Rachel. Rachel. Tonight would be the big night for himself and his sister. He agreed with Sylvia's advice that he shouldn't wait too long, and the nanites would begin boosting her sex drive this afternoon. He decided to delay her body changes until tomorrow, so he would be sleeping with the original Rachel. That seemed as if it would be important, for both of them.

He bestirred himself and got out of bed. As he walked round to the bathroom he stubbed his toe on its leg. The sergeant and the medic had both warned him that he would be clumsy as his body grew to its new size. This was obviously a portent of things to come. At least the bed-leg was somewhat giving -- the problem had obviously been anticipated.

When he arrived in the kitchen for breakfast, another large one to feed his new body, he found Sylvia making final changes to her new look. The hologram had a grey shift on this time, probably because both the children were having breakfast as well. Pat told him, "Mam's going to look like that. She'll be pretty."

"She's already pretty, Pat. She's going to be even prettier after she changes."

Sylvia smiled at the complement. "I had it do my teeth like Rachel's -- not too white. I tried that symmetry thing she did with her face, but it didn't make much difference, so I left things as they were. I had it do my fingernails as well."

David examined the hologram, which smiled to show its new teeth and stretched out its hands. "That looks fine, Sylvia. How about having it done this morning sometime?"

"Whenever's convenient. As long as Rachel can look after Pat and Mary while I'm in medical."

"Sure. I won't be putting her in the tube until tomorrow." David brought up the subject he'd been thinking about earlier, "One other thing, Sylvia. I want to get you pregnant on your next cycle, so that will be in about two or three weeks. I think it would be best to work with the grain, rather than try to force things sooner. I'll get them to set that up as well." «Do that,» David told the AI silently.

«Yes, David. Sylvia will be set to get pregnant on her next natural cycle.»

Sylvia paused at David's announcement. It wasn't unexpected, being part of the deal. David took her and her two children away from Earth, and she provided him with sex and babies. "OK, David. That will be something to look forward to."

"Rachel is going to take four months to grow into her new look," David reminded her, "so I'll wait at least that long for her first pregnancy. Having both of you with morning sickness at the same time might be too much."

"That's not something I'm looking forward to. Can the nanites do something about it?"

The AI interjected, "The underlying hormonal changes cannot be stopped without the possibility of damage to the fetus. The symptoms, such as nausea, can be reduced."

"So it won't be as bad as it could be?"

"Correct, Sylvia," the AI told her. "There will be some discomfort, but less than if the nanites had not been present." It abruptly changed the subject, "There will be a free tube at 10:03 this morning to perform the specified modifications. Is that suitable, David?"

Seeing Sylvia's nod, he told the AI, "Yes."

Pat finished his breakfast, cleared his bowl into the recycler and said, "Show it please thank you voice thing," to get his view of the Earth. At least he was learning to use 'please' and 'thank you', even if he hadn't yet got the hang of putting a pause between them.

Rachel emerged from her room just as David was about to disappear into the pod's sleep-trainer for his morning's Marine training. He barely had time to greet her, and to tell her to get Sylvia to explain the morning's arrangements, before he had to go.

When he emerged from the sleep-trainer, he was greeted with a very thorough kiss from a very naked Sylvia. "Thank you, David. I really like my new look." She stood back and twirled for him.

"Hey, you look just like your hologram, Sylvia," he teased.

"But the hologram can't fuck you like I can."

David conceded her the point. Unfortunately, there wasn't enough time for her to demonstrate it. Probably just as well. David had other plans for that evening, which a nooner might interfere with.

Over lunch, Rachel asked him why she couldn't have her changes done that afternoon.

"I haven't approved them yet, Rache," David reminded her. "Did you alter your hologram this morning?"

"No, I couldn't think of anything, though I'd still like to grow up quicker."

"Sorry, Sis. I want to keep things closer to their natural speed."

"You could still approve the changes now, David, and I could have them done this afternoon."

"Tomorrow, Rachel. I want to wait 'til then for your changes."

"Why? Sylvia looks lovely, and I want to look grown up as soon as I can." That complement got Rachel a happy smile from her fellow concubine.

"Tomorrow, Sis. Not today," David told her, and wouldn't give her any more clues.

David's afternoon was taken up with another of Sergeant Quinn's exercise sessions. Sylvia's afternoon was taken up with trying not to spend too much time admiring her new body in the mirror. Rachel's afternoon was taken up with trying to stay annoyed with her brother. That was made more difficult for her by the feelings the newly activated set of nanites were giving her. Those added feelings were making her anything but annoyed with her brother. Quite the reverse.

When David returned from his session with Sergeant Quinn, he decided to have Sylvia help him in the shower. Rachel was disappointed, as she had enjoyed herself in the shower with him yesterday. David insisted it was Sylvia's turn, so she had to bear it.

In the shower he had Sylvia wash his back. Again, she wanted to show him the difference between herself and her hologram, and again he held her off. Difficult, but he managed it. She really did look good, and her happiness at her new appearance made her even more attractive. After the shower they dried each other.

Once they were both dry, he asked, "How's your massage, Sylvia?"

"The full service, with all the extras?" she asked hopefully.

"Sorry, Sylvia. Just the plain massage."

Sylvia pouted her disappointment. She still wanted to thank David for her new body. "We'd better move to the bed. It's easier if you're lying down rather than standing up."

Sylvia was much less tentative than Rachel had been, and gave a better massage because of it. She was more prepared to use her strength to work on his aching muscles. As she worked, she talked. "Rachel gave Mister Bozo to Mary last night. She was missing her Da, so Rachel let her have the teddy."

"Really?" That surprised David. Rachel had been very attached to Mister Bozo for a long time.

"Yes. I think she saw it as something from her past, and she wants to move forward. She doesn't want to get stuck as a girl, because that won't help her grow up. She's very keen on growing up, as I'm sure you've noticed." David mmmm'ed his agreement. "I think you're right not to let her look too old straight away, despite what she wants. She's still only fourteen inside, whatever she looks like."

"Yeah," David agreed, "that's what I thought as well."

"Mary's really happy with her new cuddly toy, and I think it'll help her a lot. She's already a little better."

"Mary isn't the only one who misses Des, is she Sylvia."

Sylvia paused, thinking. "No, she isn't. It's not as bad as it was. Things caught me by surprise last night. Seeing my younger self, all of a sudden, brought back memories. I'll cope, and my new body helps. Are you sure you don't want to try it out?" She lowered herself so her nipples dragged across David's back.

David took her hint and went along with her change of subject, "Temptation, thy name is Sylvia. I'd love to, but no."

"So, you're saving yourself for my rival?" Sylvia had realized why David was delaying trying out her new, enhanced, look.

"Well, she gets her new body tomorrow, so tonight she'll still have her old one."

"Good point. That will probably help make her feel better about herself. Her new body will help as well, when she gets it. I know that mine helped me."

"Yes, Sylvia, I did just about manage to notice, despite being a man."

Sylvia laughed at his teasing her.

"Don't let Rachel know why I delayed her changes until tomorrow. I'll tell her myself later."

"OK, David."

Over dinner, Rachel could barely sit still. With David sitting next to her, she was finding it difficult to contain herself. If he didn't do something soon she'd explode! Her feelings of anger from earlier had long since disappeared. To her great relief, David asked Sylvia to clear up after the meal and look after the children. He smiled at his sister and led her into the main bedroom. They started as they had yesterday; sitting on the bed and kissing. David could sense that his sister was more eager and less nervous than before. The nanites were obviously having an effect on her.

Rachel's nervousness was pushed into the background by the new feelings that had been building in her all afternoon. She enthusiastically returned her brother's kisses, moaning as his hands reached her breasts. She thrust her chest forward, pressing them into his hands. She bathed in the sensations his stimulation of her nipples was creating. When she felt him start to lean her back on the bed, she stopped him and stood up. Quickly she stripped off her grey smock and stood before him naked. She did a quick spin to show off her body, and lay on the bed smiling at her brother.

David quickly undressed himself and lay beside her, his erection pressing into her hip. He carried on kissing her, his hands roaming more freely over her body. He wasn't getting any feeling of reluctance from her -- she seemed to be as eager as he was. Sensing she was ready, he asked, "Are you sure you..."

She stopped him with her finger on his lips. "Yes, David, I'm sure." She paused, looking him straight in the eyes, "I'm in your bed, naked. I'm here because I {em}want{/em} to be here. Please don't worry about it. I'm ready. I really want to do this."

He moved his hand to her crotch. Rachel was right, she was wet and waiting. That reassured him that she truly did want him. He began moving down her body, preparing to lick her first.

Rachel stopped him before he had got very far, "No, you don't need to do that." She had seen enough at the airport and in concubine training to know where he was heading, and why. She spread her legs further as he laid himself on top of her. His weight pressing down on her felt masculine and reassuring. His stiff prick was sliding along her outer lips, spreading her lubrication almost up to her navel.

He was trying to hold himself back, as Sylvia had advised. It was difficult; Rachel was so eager, and so sexy. He just wanted to plunge straight into her. He let her work herself up, thrusting her pussy against his cock, making sure it was stimulating her clit. When he thought she looked ready, he lifted himself off her, and moved down the bed slightly.

"David!" she complained, feeling the loss of the sensation his prick had provided. It was almost immediately replaced by the feeling of the nose of his erection pushing between her outer lips, seeking the entrance to her tunnel.

David was careful not to press too hard; the nanites had weakened her hymen, so he didn't know how much pressure it could take.

"This bit may sting, Rache."

"That's OK. Do it!" she told him impatiently.

He thrust himself quickly into her channel, shredding her virginity on the way. Once seated he stopped. Her pussy was so tight! The tightest he had ever been in. "Let me know when you're ready for me to start moving, Rache."

The pain hadn't been as bad as Rachel had feared. More like a sting than real pain. She put her arms round her brother and held him as he waited for her to tell him to start. She was glad he was so considerate of her feelings. Love and lust was such a good combination!

After about fifteen seconds she told him, "I'm ready now, David. You can start moving again."

He began slowly moving himself further into her snug channel. His dick was opening it up for the first time. Slowly he advanced an inch, then pulled back two. He made sure not to pull back too far, he didn't want to spoil the mood for Rachel by slipping free of her. Again he slowly advanced, going one inch further into her unexplored depths. Building up his rhythm, the sensations were so good. He could tell he wasn't going to last as long as he wanted to. Not surprising, since he wanted these sensations to last forever.

Rachel had already been aroused from their foreplay. The slight sting of his first penetration hadn't had much effect and his loving was lifting her quickly towards a climax. David too was approaching a peak as he increased his thrusting. All too soon they both came; Rachel's orgasm setting off her brother's immediately afterwards.

Once he had recovered, David realized that he was still lying on his sister, and quickly rolled off her. He looked at her and saw her smiling back at him.

Rachel had been momentarily overwhelmed. She was a woman! No more being a little girl. "That was..."

"Nice?" he interrupted, grinning.

She stuck her tongue out at him. "It was a whole lot better than just 'nice', David. I'm going to want you to do a lot more of that."

"Hey, who's the sponsor and who's the concubine here?" he smiled.

She looked at him, "Tell me you don't want to do that some more. Lots more."

He grinned at her, "OK, you win. Lots more."

"Good," she told him. Looking at her brother lying next to her, she saw that his erection had sagged to half-mast. She reached down and lightly stroked a finger along it, picking up some of their combined juices, which had a slight pinkish tinge. Examining her finger, she commented, "Not much blood. Some of the stories I heard in school...."

"Just be thankful, Rache. It obviously wasn't as bad for you as it could have been." No point in letting her know about having had the nanites work on her hymen, he thought.

"No, it wasn't too bad really. Just a slight sting. Once we got going I hardly felt it at all. I suppose the girls in school were exaggerating things. None of them had ever actually done it, I don't think."

"Probably not," David suggested. "Twelve would be pretty young to have started sex."

She nodded at that. Then she asked him, "Are you going to get me pregnant soon?"

"No, not immediately, Rache. The AI says it's better to wait until you've finished growing into your new shape, in four months time."

Thinking about her brother's answer, she suddenly had an insight, "This was why you delayed my new body until tomorrow, wasn't it? You wanted to make love to the old me, before any changes?"

David nodded. "Got it in one, Sis. I wanted the real you."

"Thanks, Bro." She kissed him briefly. "Mind you, with all the other changes over the last few days, I'm not really sure what the 'real me' is like now. I seem to be a moving target."

"I think you've come most of the way you need to Rache. You've done pretty well, considering. Coping with things since we've been extracted hasn't been easy for you. A bit of a shaky start..."

Rachel winced, and nodded.

"... but once you got your feet under you, it's been going a lot better," David finished his thought. Rachel smiled in appreciation of her brother's praise. "Thinking of changes, Sylvia has been after me so she can thank me for her new look. I'll probably won't be able to hold her off tomorrow night. Remember that you're going to have to share me with her."

"Well," Rachel told him, "if I'm going to have to share you, then I'd better make the most of you tonight. We need to get plenty of practice, so I can be sure to get pregnant in four months time." She reached for her brother and started to pull him over on top of her, using his convenient handle.

Something Sylvia had said was niggling at the back of David's mind, "There's something I wanted to tell you ..." Her hand on his returning erection was too distracting, so he went along with her request and rolled into position above her.

Rachel wiggled her hips to get him comfortably positioned between her legs. She gently slid the tip of his stiffness into her wet channel. Good, she couldn't feel any more pain from her torn hymen. "Later, David. You have something else to do first."

"We have something to do," he corrected her.

"OK, 'we', but let's do it now."

He drove into her again, not having to restrain himself so much this second time.

Having cum once already, David managed to last longer this time than he had before. Rachel got off twice before he filled her with his second load. When they had finished he moved off her so as not to crush her. After a few seconds lying next to each other, she rolled over on top and kissed him.

"Hey, you're dripping all over me, Rache."

"And whose fault is it that I'm dripping, dear brother? Who put it all up there in the first place?

"Guilty," David laughed, before wrapping his arms around his sister and kissing her in return. "What I wanted to say, before you interrupted me, was thanks for letting Mary have Mister Bozo. I know he means a lot to you, and it must have been a big wrench to give him away like that. Sylvia said that Mary's really happy with him."

"Yes," Rachel agreed, "Mary loves him to bits. It was sort of like giving away my childhood. Still, he's a child's toy really. I was sad at first, but now that I'm a woman," she bumped David with her hips to make sure he got the message, "I should leave childish things behind. Anyway, I've got myself a brand new Mister Bozo."

He looked at her, puzzled.

Rachel grinned, and kissed her brother on the nose. "He's cuddly," she kissed his nose again, "I love him," kiss, "he loves me," kiss, "he's still silly," kiss, "and he's still a boy."
