Chapter Three - Growing Up

As she walked back to the pod beside her brother, Rachel was silent; she was so distracted that she didn't even notice her own nakedness. She'd made a complete spectacle of herself in front of everyone, and not for the first time.

Thinking it best to leave her to her thoughts, David kept quiet also. He remembered his earlier puzzlement, so he took the opportunity to query the AI sub vocally, «Is the Fleet Auxiliary about replacing Navy people on colony ships, and getting them onto warships?»

«Affirmative, sir. The Fleet Auxiliary will be used for non-combatant missions, such as crewing colony ships, inter-system supply delivery and personnel transfer. This will release trained naval personnel.»

«There is nothing about the Fleet Auxiliary on Earth.»

«It is felt that if information were readily available, then there would be too many volunteers for the non-combatant options, and not enough for the combat branches. There is a small amount of information released to Earth, but it is only shown on request, and even then only to those people whose CAP scores indicate that their usefulness in the combat branches would be limited.»

Walking alongside David, Rachel was lost in her thoughts. Nothing she did ever turned out right. She felt a complete failure. Dad was right, she was just a useless girl. She couldn't even succeed at being a concubine, Sylvia was much better at it than she was. Life was just ghastly.

Once they were back in the pod, David just sat with Rachel on the sofa and put his arm round her shoulder. He wasn't sure what to say to her, in case he made things worse. Eventually she solved his problem for him, "I messed things up again, didn't I?"

"You're not the only one, Rache," he tried to reassure her. "Didn't you hear Kenisha talking about the sweepstake? It must happen every trip. And there was another concubine who was sick, as well as you."

She didn't seem to hear him. "I'm always messing up. I left my CAP card behind. I couldn't handle being naked. You and Sylvia have to look after me all the time. I'm no good with her kids. I threw up in the dining hall. Sylvia's a much better concubine than I am. I'm useless." She threw her arms around David and wailed onto his shoulder in despair, "I want to go home!"

David just held her tight and made reassuring noises, hoping she would be better in a bit. Thinking about why she had thrown up, he had another silent conversation with the AI, «How old was that concubine induction video of the woman being recycled?»

«Eight weeks old, sir.»

«Was it taken on this ship?»

«No, sir.»

He decided to confirm his suspicion, «I presume that recycled corpses do get reprocessed into food as well as other things.»

«Correct, sir. We need to make the most efficient use of the resources available on board ship.»

«Has anyone been recycled on this ship since it arrived in Earth orbit?»

«No, sir.»

«Please notify me silently if anyone has to be recycled during our journey.» David wanted to be able to warn Rachel before she ate, rather than having her find out after the event.

«Affirmative, sir.»

As he looked around he noticed that the AI had set up Sylvia's new color scheme in the pod. It was certainly better than the grey it had been before. Anything to distract him from worrying about Rachel.

When Sylvia returned with Pat and Mary, she took in the situation at a glance. She retrieved Mister Bozo from Mary and shooed both children upstairs. Rachel unwrapped an arm to grab her teddy bear, and Sylvia disappeared after the children. David just sat and waited until his sister had cried herself out.

"Your uniform is all wet." Rachel was more-or-less back in control of herself.

"I can always get another one. What about you?" David asked anxiously.

"I feel a bit better. Can I just lie down again? It seemed to help before."

"Of course, Rache. Don't be too hard on yourself. You're getting a lot of new stuff thrown at you in a short time." He was trying to be reassuring.

Rachel smiled faintly and nodded. She knew David was trying to help, but things were very difficult for her at the moment. She did indeed have an awful lot of new stuff to take on board. If only father hadn't kept her so sheltered, she might have been able to handle it better.

Once Rachel was settled in her small bedroom, hugging Mister Bozo tightly, David returned to the main room and got to thinking about his sister's CAP scores. He'd known that he was going to take her, whatever her scores were, so he hadn't even bothered to check her CAP card at the airport. Turning towards a blank wall, he got the AI to display her CAP results for him.

The numbers showed that she was timid and unsure of herself, with a slightly low self-image. Her potential motherhood score was good, though it was mostly potential. Her experience helping their mother with young Abel, had helped change some of her potential into actual. The sex score was good, rather better than David had expected. Obviously she had been repressing that side of herself while living with Dad. Perhaps that part of her duties as a concubine wouldn't be too bad for her. Once she got used to it, she should enjoy it. He wondered how much the rest of her CAP score had been distorted by having to live with their father. It might be interesting to see how well she did when she retested on her fifteenth birthday.

David got up, ditched his old uniform into the recycler and retrieved a new one from the replicator. "AI, what's with the rank badge? Why the letter 'A'?" He had a single gold bar with a letter 'A' embossed on it. He knew that the gold bar was for a Sub-Lieutenant but the 'A' was new to him.

"Lieutenant Legere ordered them, sir. You are an Officer Cadet which is also known as an Aspirant in the Canadian armed forces. The 'A' stands for 'Aspirant' and differentiates the bar from that of a Sub-Lieutenant." David nodded, and called up a Marine training vid to pass the time.

Sylvia interrupted him, coming down with the children in tow. "How's Rachel doing?"

"She's calmer and resting in her room with Mister B. And by the way, a nice job with the color scheme."

"Why thank you very much, young master." She smiled and gave him a mock curtsey.

David grinned, and muttered about insubordinate concubines.

Sylvia laughed, and went on, "The AI fixed the kids' bedroom as well, so Mary should be happier." She smiled at her younger child.

"Yes, Mam," Mary told her, "I like it now. I didn't like it on my own. It was scary."

Sylvia turned back to David. "I have to take these two off to medical, for their initial checks."

David smiled, and nodded for her to take the children.

Soon after Sylvia and the children left, Rachel re-emerged, interrupting David's video for a second time. She had tidied herself up, and was wearing a new smock. "Can we talk, David?"

"Of course, Sis." He shut off the vid, and patted the seat next to him for her to sit.

She sat down and took hold of his hand. At first she didn't look at him, just staring downwards, talking to her knees. "I was thinking about Dad. I still love him, but.... Well, he took me out of school just before my thirteenth birthday. I think he wanted to keep me at twelve years old, keep me sheltered, and keep me away from stuff about the Swarm. What you said yesterday about 'English, Math and the Bible' was right."

"So you were taking some of it in?"

"It was strange," Rachel explained. "I was sort of frozen, watching myself in a film of what was going on. I could see it, and hear it, but I couldn't do anything in it. Anyway, Dad wanted to keep me at twelve years old. But I'm not twelve, I'm fourteen. Typical Dad. If things weren't the way he wanted them to be, then he'd ignore the bits he didn't like and pretended they didn't exist." She paused, collecting her thoughts, and turned towards her brother. "I think that a lot of the problems I've been having, since the airport, are me trying to grow up two years in the space of two days." David started to reply, but she stopped him with a gesture, putting her finger to his lips. "Being away from Dad has given me the chance to grow up. I don't think I've finished it all yet, but I hope I'm over the worst of it. Thank you for taking me away David." She leaned forward and kissed him on the lips. He was even more surprised when he felt a little tentative tongue added in. She pulled back and giggled. "The look on your face!" She kissed him again, briefly, but no tongue this time. "I'm fourteen, not twelve, so I need to catch up on a lot of stuff. Kissing and boys and babies sort of stuff."

"You're certainly not twelve any more, Rache." He thought of something, «AI, have the nanites started affecting her libido yet?»

«No, sir. They are not due to activate until tomorrow afternoon.»

So, David realized, the kissing was all Rachel and not the nanites. "I think it should be fun learning stuff together," he told her. "Especially the kissing and babies stuff."

Rachel smiled, "I thought you might like that part. I think I will too."

They were sitting on the sofa, still holding hands, and talking when the AI interrupted. "Officer Cadet Harlow, you are due for an exercise session in the gym in fifteen minutes. You should change into your fatigues for this duty. They are in the closet in your bedroom."

"Rache, will you be OK on your own 'til Sylvia gets back?"

"Yes, I'll be fine," she reassured him. "I've calmed down a lot now. I can watch some concubine training videos while I wait."

David's exercise session was run by Sergeant Quinn. "You're all having the standard Marine body enhancements, so you're all going to need to get used to your new larger bodies. There are two ways to do this: dancing and martial arts. No prizes for guessing which one we will be doing." David managed a rueful grin at the sergeant's joke. This session probably wasn't going to be easy. "To start with you won't be sparring," he told them. "The reason for this is that we don't want you injuring each other by accident. When you pull a blow one inch short of putting your opponent's eye out, and your arm is two inches longer than you expected, things can get very very messy. And 'messy' isn't allowed in the Marines. Until you are properly used to your new size, we will be using inanimate targets: makiwara, punch-bags and similar, so we don't overload medical. You'll be sparring with each other by the end of this voyage, so listen and learn well now."

Back in the pod, the two women were watching the children play. Rachel asked, "I suppose it's easier with two, because they can play together. Abel could be a handful when he wanted to play, and wouldn't take no for an answer."

"Yes," Sylvia agreed. "When it was just Pat, he only had me to play with, so he took up a lot of my time. Very insistent he was. Once Mary was old enough to be able to play with him, it got a lot easier. That will help us later, once we start popping out more babies in a few months time."

"Sylvia, can I ask you some questions?"

"That sounds serious, Rachel."

Rachel blushed. "Well, sort of. My Dad didn't let me know anything about sex. Mum helped a bit, but back then I didn't know much about what to ask. I saw some of what went on during the pickup at the airport, and there were a lot of things they showed at the concubine briefing as well. I wanted to ask about them. I'm embarrassed to ask David, so I thought I could ask you."

"Ask away," Sylvia smiled, "I'll do my best." She was pleased that Rachel felt able to ask her such questions. It showed the teenager trusted her.

"Well, when they showed that woman putting his thing in her mouth. How was she able to take so much of it? She had her nose in his hair."

"I really don't know the answer to that," Sylvia replied. "I tried to go deep with Des, but I couldn't get him anywhere near that far down my throat. I did notice that the concubine in that bit of the video looked as if she'd been enhanced by her sponsor. It may be something they can do to us in medical. I think we get a second visit where they make us look like porn stars." She held up her hands, indicating a large imaginary bust.

Rachel giggled in response. "I wish mine would grow more. I've got all tall, but my boobs are still tiny."

"Give them time," Sylvia advised, "and if that doesn't work, then ask David to make them bigger."

"I might do that if they don't get a move on. I'm sure David wouldn't object. Don't all men like big ones?" They both fell to giggling again. Rachel returned to her questions about blowjobs, "It must be really strange, to be able to suck one all the way in. If I tried it, I'm sure I'd gag and throw up again."

"Me too," agreed Sylvia. "I knew Des would have liked it, but there was no way I could get him down my throat. I could take his first few inches fine, but no more. When he reached the back of my mouth I had to stop him."

"Do you miss Des, Sylvia?" Rachel asked.

"Yes, of course I do," Sylvia replied, seriously. "There's a big hole in my life where he was. I expected it to be red raw, but it's actually more numb than raw. That makes it a bit easier to bear. Your brother is very nice, and he's doing his best, so that helps. Having the kids with me is good as well. I'm sure Des is missing all three of us. It's not as bad as I imagined it would be, but that might be part of what they did to us in medical. I know they can do a lot of things, and that's an obvious one. A lot of us have had to leave people behind."

"Yes, I do miss Mum and Dad. Mum more than Dad, but like you say it's more numb than raw. Maybe you're right and it's something the nanites do to us." Rachel paused, "I have another question about sex. Some people were doing it in the wrong hole. In their behinds. 'Anal sex' I think they called it in the film. Did you ever do that?"

Sylvia blushed slightly in embarrassment. Still, she had promised to answer Rachel's questions, and didn't want to disappoint the teenager. "Yes we did. After we were married we tried a few different things. I didn't like it as much as the normal way, so Des didn't insist. After they announced that the Swarm was coming, we started doing it again. We'd heard about what went on at extractions, so we did anal about once a week to let me get used to it. I might have had to do that at a pickup to get myself a sponsor. I even carried a small tube of lube in my handbag, just in case. As it turned out I didn't need it at all. It's not too bad if the man is gentle and takes his time, but I prefer it in the usual place."

"Do you think David will want to do that with us?" Rachel asked the older woman.

"Well, he hasn't asked me yet, but he'll likely want to try it sometime. It isn't as if we can say no to him. When he does decide to do it, I'm sure he won't be rough about it. He doesn't want to deliberately hurt either of us. It's not that bad as long as you can relax, use plenty of lubrication and he takes it slowly."

"You're right," Rachel said, "I don't think David wants to be nasty to us." She paused for a moment, "Do you really think he'll want to do that anal thing? Doesn't it get all... well, dirty?"

"I think he'll probably want to try it at least once. As to the dirty bit, you have to clean yourself out first. That way it's not too bad. It does mean planning in advance though, so it can't really be spontaneous."

"Mam, look at my drawing!" Pat interrupted. Once Sylvia had praised his doodle, and sent him off to colour it in, she asked Rachel, "What about you, going to have sex with your own brother! I had two brothers, and I couldn't imagine doing it with either of them."

"It's weird," Rachel explained. "I know I shouldn't want to, but David was the only boy I could actually talk to. Dad only allowed me to meet girls; boys were definitely off-limits. The Church youth group was very strict about making sure girls my age weren't talking to boys. David was all I had really. It'll be strange enough with it being my first time and all. It's almost as if the incest part doesn't matter so much. I know it should matter more, but somehow it doesn't. I do love David and I know he loves me. I didn't have any boyfriends, so it was always David or nothing."

"You poor thing," Sylvia replied sympathetically. "I had plenty of local boys to pick from, so there was always an alternative to my bratty brothers."

"Bratty brothers?" David interrupted and made them both jump. He had just arrived back from his gym session, and had caught the tail end of their conversation.

"My two brothers," Sylvia quickly explained. "They're both younger than me, and were both bratty. Always trying to get peeks at me in the shower."

"Talking of showers," David said, "I need one after my torture session with Sergeant Quinn. One of you can come and help me wash my back." He smiled at them both, and headed for the big bedroom, unfastening his fatigues.

The two women looked at each other and laughed. "Looks like you're going to get to peek at your brother in the shower then," Sylvia said with a grin.

"Oh no! I couldn't," Rachel protested, embarrassed.

"Yes you can. Go and help him while I keep an eye on the kids. You said you had a lot to learn, so you can get started now."

In the shower David was wondering which of them it would be. He had deliberately left things ambiguous, hoping it would be Rachel. She'd said that she wanted to learn about 'stuff', and this would be a way to see if she really did. He had kept his back to the door, but could sense someone approaching him from behind. Her hands on his back felt very tentative. Looking down at her feet he could tell it was Rachel. Good. She was taking the initiative. "Mmmm, that's nice," he told her. "Rub me harder, my muscles took a pounding from the sergeant."

Rachel complied, using more pressure on David's back, but kept quiet. She wondered if he knew it was her, rather than Sylvia. Probably he did, but the small amount of doubt allowed her to pluck up a little more courage. This was the first time since they were very small children that she had seen her brother naked, even if just from behind. It was the first time she had really seen any grown man naked. There had been a few naked men at the airport, but she'd been too wrapped up in her own problems to notice them much. She'd giggled over a few naughty pictures in school, but that was over a year ago. Pictures didn't have the same impact as actually touching David; feeling his skin under her hands and his muscles under the skin. Touching his bare back was giving her unfamiliar sensations. Her heart was beating faster, her nipples were tightening and she was getting a tingling between her legs.

David turned round, and burst out laughing. Rachel hadn't taken off her grey concubine shift before getting into the shower. She stood there with the warm water pouring over her, soaking the garment and making it stick to her figure. He could see the bumps of her nipples under the material. He embraced her with both arms and hugged her to him, "You forgot to take your clothes off, Rache."

"Did not," she replied, hugging him in return. "You've seen me with nothing on, so it's only fair that I get to see you too. You stayed dressed when I had to undress yesterday, so I stayed dressed now."

David smiled and stood back from his sister, so she could get a good look at him. He wasn't erect, but he did have a lazy lob as his dick became aware of the woman in his fourteen year old sister. He could see her looking at him, blushing, eyes wide, but not looking away.

«AI, turn off the water.» He wanted her to be able to get a clear view of him, without the shower interfering.

Once the water had stopped, David turned slowly round so she could see all of him. He was pretty much unchanged; the nanites hadn't yet had time to make any real visible difference. He was still slim, without much fat, so his muscles showed under his skin. Not a six-pack, but certainly not overweight and with a nice tight bum. She had made a fair point, that he'd already seen all of her, so he didn't mind showing himself off for her to look at. Soon they would be doing a lot more than playing, 'you can see mine if I can see yours,' but they had to start somewhere. He didn't want to push her too fast at the start in case he frightened her off. It was a good sign that she had taken a small initiative by coming into the shower. Very different from the way she'd been yesterday. A good difference.

"It's a lot bigger than Abel's," Rachel said, looking at his cock.

"Abel is only two. Boys' dicks are like girls' breasts, they get bigger when we hit puberty."

Rachel nodded at that. "Does it... you know, stand up?"

"You must be cold in that wet shift, Rache. Why don't you take it off, and you can see it stand up just for you."

Rachel blushed even more. She had spoken without thinking of David's possible reaction. Still, he had seen all of her earlier, and he was naked for her now. She grasped the hem of her garment and pulled it up over her head. She threw the soggy shift aside, and turned slowly for her brother, just as he had turned for her.

David took his time looking. Yesterday he had deliberately tried not to stare at her; she had been too upset for that. Now that she was more accepting of her nudity, he could take his time examining her. Her legs were still a bit thin from her recent growth spurt, the sort of legs that suited a catwalk model, rather than a real woman. Where they met, her sparse brown hair, wet from the shower, was plastered flat. Her hips and waist were definitely there, though at fourteen she still had a way to go to attain her fully female shape. Despite that, there was no doubt at all about what sex she was. Her breasts were about the shape and size of half an orange, with brown areolae. They weren't quite big enough for gravity to have shifted them to pear shaped yet. He could see from the state of her nipples that she was beginning to get excited. Sylvia's were bigger, but Rachel's looked absolutely delicious. As she turned he could see her bum: small, tight, and nicely rounded.

As Rachel completed her rotation, she could see that his cock was already bigger. She could even see his heartbeat, from the blood pumping into it as it reached towards the vertical. She was utterly fascinated by it, never having seen anything like it before.

David smiled as he watched her. He could see that she was completely mesmerized by his growing erection.

"Will it squirt?" she asked him suddenly.

"Let's both get dried off first, Rache," David suggested. "We can make it squirt in the bedroom. Bring a washcloth with you as well, to clean up afterwards."

As if by mutual consent, they turned their backs on each other to dry themselves. Rachel was still nervous and David didn't want to press her too hard. Finishing first, he went through to the master bedroom and lay back on the large bed to wait for her.

Once his sister emerged, still rather nervous, he patted the mattress by his side for her to sit. At first he just lay there quietly, letting her look at his erection, and not staring at her too obviously.

"It won't squirt on its own," he told her, "even from looking at a pretty girl like you. We have to help it along." He took her hand in his and wrapped their fingers round his erection.

"It feels soft outside and hard inside," she told him. "The skin is kinda loose around it." Worried, she asked, "You're not going to put it in me now are you?"

"No, Rache," he reassured her, "not today. For now we'll just make it squirt." Suiting his actions to his words, he squeezed his fingers a bit more tightly around hers and began to move their joined hands up and down his cock.

Rachel watched, fascinated, as her brother masturbated himself with her hand. She could see his hips making small thrusts as he drove his cock through her grasping fingers. He managed to explain about the flange below the top, where things felt best for him. She could sense him tightening his grip slightly each time the ridge passed through their hands. As he approached closer to his climax he became increasingly incoherent until finally, with a big groan, he spurted his cum all over his torso. Rachel had tried masturbating herself a few times, but she had never been able to generate anything as intense as David seemed to experience. She picked up the cloth and began to clean his cock.

"Not there, Rache, it gets very sensitive just after an orgasm. Clean up the rest of me first, and then go back to my dick."

"Sorry, David, I've never done this before."

"That's fine, Rache." He smiled to reassure her. "I know all this is new to you. A bit more than you got in school, or from Dad, I think."

"I'll say!" She carried on wiping up the residue. He had shot it so far! "School treated everything very clinically, and there weren't any live demonstrations like that. Dad told me nothing at all, though Mum was able to help a little. Thanks for showing me." She bent down and kissed him on the lips, again using her tongue slightly. "Can I finish cleaning you now?" When her brother nodded, she wiped his softened cock clean, and then bent down to give it a very quick kiss on its head. She immediately giggled at her own temerity.

"Rachel!" David burst out, "You're getting quite adventurous now you're away from Dad. I bet you haven't done that to any of your boyfriends before."

She grinned, "Dad never let me have any boyfriends at all. You're my only boyfriend, ever, David." She hugged him and gave him another kiss, on the lips this time. "Are we going to do more now?"

David thought a bit, "Not now. You're doing very well, better than I thought you would. I don't want to go too quickly. We'll take things step by step. Let's get dressed and go back to see how Sylvia and the kids are getting on. We can do some more after we've eaten."

Rachel smiled at that. Now that she had overcome her initial confusion, she was enjoying trying out new things with David. She knew that he didn't want to hurt her, and that he wouldn't push her too hard. She trusted him.

All five of them were gathered in the kitchen. Sylvia was finishing preparing the food while Rachel and David were setting the table, with Pat supposedly helping. Mary was playing happily with Mister Bozo.

Sylvia asked Rachel, "Will you be all right with replicated food, dearie? After what happened at lunch...."

"I think I'll be OK, Sylvia," she replied, "I'm a lot better now."

David interjected, "I talked with the AI. That video you saw was weeks old, and taken on a different ship. Nobody has been recycled so far on this trip, so the replicated food is OK. The AI will let me know if it does happen, so I can warn you, Rache."

"We could get some tins and suchlike out of the replicator now, just in case," Sylvia suggested. "If they had to recycle someone, then we could live off the tins for a meal or two."

David looked at Rachel, who nodded. "That's a good idea Sylvia," he agreed. "You and Rachel can get together after the meal and organize it. I like rice or pasta, so you could include some of them as well. They're easy enough to keep."

When Sylvia announced that the meal was ready, David sat next to Rachel. He was soon feeding her forkfuls of food, and she was feeding him. They didn't quite get as far as kissing each other, but it was a close thing. David was glad that Rachel was reacting so well to his slow, and somewhat inexpert, seduction.

It was made easier for him by Rachel wanting to be seduced. She had become much more settled in herself after her crises over the last two days. She was more aware of what she actually wanted, as opposed to what her father had told her she should want. Often those were two very different things. Since the airport, she had known that she would sometime soon be making love with David. At first the thought both attracted and terrified her. The way David had let her take things pretty much at her own pace had increased the attraction and reduced the terror. The terror was still there at the back of her mind, but it was much more bearable now. Having sex for the first time would be something big for her, and she knew so little about it. Being nervous at first was only to be expected. She trusted David to do his best to help her through all the new things she would have to do with him. She had certainly enjoyed herself with him in the shower and afterwards. She felt deliciously naughty, and feeding David helped keep those feelings bubbling along.

After the meal David spent some time with the two children. Mary, especially, was not completely used to him, so he wanted to overcome that barrier. He didn't know how much time he would be able to spend with the two of them once they all arrived at the colony and he started full-time officer training. He wanted to make sure that she was used to him by the end of the voyage. Pat was reading his book, with David on one side, helping him, and Mary on his other side, away from David, looking at the pictures along with her brother. She was a little shy of talking directly to David, but listened carefully when he explained things to Pat.

When Sylvia and Rachel had finished putting away the tins and rice from the replicator, they came back into the main room. David asked Rachel to go and get Mister Bozo from where Mary had left him in the kitchen after the meal. When she returned, he sat Rachel on his lap while she held Mister Bozo in her own lap. He announced to the two children that he was going to sing a song about Rachel:

During the song he was bouncing Rachel up and down on his knee, in time to the words. Rachel got into the spirit of the thing by bouncing Mister Bozo in her lap as well. The kids were laughing, as was Sylvia -- especially after the last line. Rachel was giggling, and going pink at the pun.

"You're rude, David," she told him, "but it was nice of you to make a song about me." She gave him a quick kiss.

All five of them stayed together, playing and talking until the kids' bedtime. Sylvia made sure that David and Rachel each got goodnight kisses from both the children, and then took them up in the grav-lift for their bath. David took Rachel to the bedroom. "We're going to carry on with what we were doing after the shower," he told her. "Stuff, you know," using their code word.

"Yes, stuff," Rachel replied, as she followed him, with a mixture of nervousness and anticipation.

David started by sitting next to her on the bed and kissing his sister. Rachel had briefly used her tongue when kissing him before, but this time he used his tongue to intensify the kiss. Rachel soon caught on, and her tongue became as adventurous as David's. As his hands moved round from caressing her back, towards her breasts, she tensed slightly. His gentle approach to them soon had her relaxing, and relishing the new sensations, as he softly stimulated her nipples through the thin shift. David silently thanked Sylvia for her tuition; he could sense Rachel's reactions, and was using them to guide his manipulation of her breasts.

"I'm sorry they're so small," she said during a break in their kiss.

"Nonsense," David replied, "they're just the right size for my hands," suiting his actions to his words. "Anyway, Sylvia has big ones, so yours give me more variety. There's no point in having both of you the same. If I'd wanted that, I'd have picked a pair of identical twins at the airport." As his hands cupped her titties, he restarted their kiss to stop too much conversation; he had other ideas on his mind. Maintaining their kiss, he pressed her slowly back so they were lying next to each other on the bed. Moving one hand down he stroked her bare thigh, close to her knee. Rachel tensed a little at first, but she soon relaxed when he kept his hand away from her sensitive areas. He wasn't moving it upwards, just lightly rubbing her leg a couple of inches either way.

"I really enjoyed it when you used your hand on me, after our shower, Rache," he whispered to her. Her arousal increased at the memory, and she blushed slightly. "I want to do the same for you now." He slowly began moving his hand up her thigh.

"I'm not sure...," she said tentatively.

His hand was gradually approaching his target. He could smell the beginnings of her arousal. Similar to the way Sylvia had smelled, but different.

"You'll like it, Sis. I liked what you did for me, and you'll like what I'm going to do for you." He removed his hand for a moment, to lick his fingers, and replaced it on her thigh, just below the hem of her garment. Once there, it resumed its slow progress, gradually moving up under her grey shift.

Rachel twitched when his fingers reached her outer labia, "David..."

He stopped her talking with another kiss, and moved a fingertip slowly inside her. He needn't have bothered with his own saliva, she was already well lubricated with her own juices. He stroked lightly just inside her lower lips, not yet approaching her clitoris. He could feel her relaxing as he worked gently around the entrance to her vagina, being careful not to actually penetrate. Soon he felt she was ready for him to proceed. He moved his finger slowly up onto her clit, which had begun to emerge from its hood.

"Oh my goodness!" she exclaimed, breaking their kiss. "What are you doing David?" He ignored her protestations and continued to gently massage her button. "That feels... ooohh.... That feels nice."

He propped himself up on one elbow, and smiled down at his sister, while continuing to work his fingers between her legs. He watched as the different emotions passed over her face: worry, acceptance and pleasure.

"David, I feel.... Oh my.... Ohhh.... Ahhhh." Rachel collapsed into incoherence as her orgasm hit her. She just lay there, overwhelmed by the sensations she had experienced.

David thought she looked wonderful as the ecstasy hit her. He was seeing the sensuous Rachel that was indicated by her CAP sub-score, but which had been suppressed by their father. When she had recovered a little, David quietly told his sister, "It's much better when someone else does it, isn't it, Rache?"

She was barely able to reply, "Yes, absolutely. That was... amazing."

"If you're a good girl, we can do it again soon."

"Thanks, David, but not too soon. You can have too much of a good thing."
