What I'm Going To Do

My father died when I was a small child and my mother subsequently married a widower with a single daughter, one the same age as me. This meant that my sister is really my step-sister, and not a blood relation.

As we matured we developed in different ways. I was more the intellectual type, an introvert with a love of mathematics and logic and computers. Suzy, on the other hand, was your classic extrovert, very much into athletics and sport, totally unable to understand why I'd want to spend time on a computer rather than out playing sport.

Despite our differences we all got along quite well. I set up an online company while still at school, developing it while continuing my studies. The company took up a lot of my spare time but I was making some money out of it and I could see it had potential to get bigger.

Fast forward a couple of years and the economy took a bit of a downturn. My father's company also took a bit of a hit and he was struggling to make ends meet. I, being a typical teenager (nineteen now) and totally wrapped up in my own interests, failed to notice this. As far as I was concerned everything was the way it had always been.

This obliviousness landed me right in it one fine Saturday morning. I'd wandered into the kitchen in search of breakfast in time to hear Suzy complaining about the state of her wardrobe. My mother was consoling her but not offering to replenish the wardrobe which I found mildly surprising. I looked at Suzy and grunted.

"Susy's got a point," I blithely observed. "That stuff she's wearing right now looks like crap and it's way too tight across her boobs. No way should she be going out like that. Definitely time to upgrade."

My mother blushed and Suzy went up like a rocket.

"If some nitwit had been listening properly instead of just eavesdropping on a private conversation and then sticking his nose in where it's not wanted he might have heard that we can't afford to get new clothes right now. If said nitwit had a paying job he might contribute to the household budget like other members of the household, rather than sitting behind a computer and playing games all hours of the day."

"I'm not playing," I said mildly. "I'm working. I do run an online company, you know."

"I said a paying job," Suzy snapped.

"My company earns money. I'm quite happy to contribute to the household budget. If anyone had bothered to suggest it I'd already be doing so."

"Do you mean that your company actually makes money?" asked my mother, sounding highly surprised.

"Well, sure. What's the use of a company that doesn't? Anyway, my expenses aren't very high so I'm able to bank most of what I make. I have some savings and some investments."

"Then I'm sure you'll be delighted to start paying board," Suzy put in quickly. "How about half the earnings from your company?"

"Bit steep," I told her. I turned to face my mother. "How about a hundred a week? I'll back date it for a year and pay last year's board and the next year's board right now. You can remind me in another year that more board is due. Let me have your bank details and I'll do a transfer right now."

My mother just looked stunned. Even Suzy had nothing to say.

"Mum, your bank account details?" I prompted.

"Oh, I don't know. Why don't you go and ask your father. He'll know them."

So I went and explained things to my father. Apparently he was also surprised to find that I actually made money online. He gave me his account details and I went to my computer and did the transfer. I gave him the nod to go and check it out and returned to my interrupted breakfast.

"Transfer done," I said. I pulled out my wallet and extracted a credit card and passed it over to my mother.

"Why don't you take Suzy down to the mall and the pair of you can replenish your wardrobes. It's on me as long as you don't exceed five thousand. That's between you. Not each."

"Martin, I can't do that," my mother protested, trying to return the card.

"I can," said Suzy, grabbing the card. "If he's silly enough to offer I'm not so silly as to say no."

"Are you sure that you can afford it? I'd hate for you to leave yourself short."

"Mum, I have over a hundred thou in that account. Five thou for some dresses or whatever won't kill me."

"What do you mean, that account?" asked Suzy. "Do you have other accounts?"

"Several others," I admitted. "Company and investment accounts mainly."

Shortly after Suzy headed down to the mall, dragging mother with her. My father was watching them go, smiling.

"Nothing like shopping to make a woman happy," he observed. "How much does your company make in a year?"

"Varies," I said. "This year has been pretty good so far. If the current trend continues I should clear about five million after taxes."

"What?" I asked, seeing he was just standing there looking at me. "I'm good at what I do and the proper App can bring in a mint. I'm thinking of selling the company. I've been offered a good price by a firm wanting to get a toe in the door of the App market. They think I'm ripe for a takeover and I think they're right. I've been thinking of switching to something that's more substantial in the way of products. If I sell I'll be in a position to start a new company and really put together some software I want to write."

My father just shook his head. Why do parents find it so hard to believe that a child might grow up and become successful? I decided to send a message to the prospective buyers expressing interest in their bid.

"Oh, dad, don't tell mum or Suzy about how well the company is doing. I like to keep a low profile. Just let them know it's successful."

Suzy of course wanted to grill me that evening about what my company did.

"We write specialised Apps and some generic games," was my general explanation. "The specialised Apps tend to be custom orders. The amount you get depends on how many copies that the firm expects to distribute. Take Uber, for example. They have around a hundred million people using their app. If the developer of that app only got a cent per copy that's a million dollars, and no, that's not one of my apps."

"Well what apps have you written and what do they do? How do they work?"

"That's commercially restricted information," I explained. "Some of my more successful apps use quite a bit of higher mathematics. It really boils down to should you know what I do and would you be able to understand it if you did? The answer is no in both cases."

I smiled benignly while Suzy fumed. Maths had been her poorest class. English she did well at but maths? She couldn't stand it.

The parents took advantage of their unexpected injection of cash to have an evening out. I had no intention of going out and Suzy was staying home to sort out her new wardrobe, gloating over the things she'd bought. I suspected that she got the lion's share of their wardrobe money, although mother had had a number of parcels.

I was dressed for bed and just lounging on it playing Bejeweled Blitz. (Don't look at me like that. I just happen to find the game relaxing. So sue me.) The door opened and Suzy came waltzing in and if I'd had false teeth I'd have swallowed them.

She was wearing part of her new wardrobe, to wit, a brand new nightie and negligee. The nightie was more there in concept than actual material. I bet she didn't show mum when she got it. The negligee had somewhat more material than the nightie, although this tended to be negated by the fact that it was see-through, and I could most definitely see through it to what lay underneath. I'm quite sure that a nightie like that would have come with a matching pair of panties, but Suzy seemed to have forgotten to put them on. I was able to observe that she hadn't forgotten to shave.

Something else that was evident was that part of the reason Suzy needed a new wardrobe was that her chest was somewhat larger than it used to be. With the amount of flesh she was showing I don't know why she even bothered to put the nightie and negligee on. Probably reluctant to walk into my room completely naked, although that might have been easier to take.

My reaction to Suzy dressed like that was instant erection. (Step-sister, remember. Not a blood relation.) That erection was so instant and so strong that I half expected it to rip my pyjamas open.

Suzy spotted the instant bulge and she had an evil smirk on her face. She sat next to me and her hand reached for me, slipping her hand into the open fly before I could react in time to stop her. (Stop her? Was I mad?)

"Okay, Mr BigBusinessMan, let's see if you know what I'm going to do and if you'll be able to understand it."

I'd a pretty good idea of what she was going to do. My only question was just how far was she going to go? From her comment it seemed she was slightly miffed that I'd implied she wouldn't understand my business but surely this reaction was a bit over the top.

Suzy obviously didn't think so as her hand slipped through my open fly to find my cock which she promptly hauled out into the light. Free from constricting clothes, and encouraged by being held by a hot little hand, it promptly resumed its efforts to stand tall. Suzy was giggling.

"My, my. You have a little more than I suspected," she told me. "This could be interesting."

I wasn't a virgin and I'd strongly suspected that Suzy had lost hers even before I lost mine. (Easier for a girl to lose hers than a boy. They just have to lift a finger. Boys have to get down on their knees and beg.) Not that I'd ever queried her virginal status, considering it none of my business.

With that comment she bent over me, her head descending, her mouth engulfing me. Then her head started bobbing up and down as she started working on my cock. Despite the distraction of what she was doing to me I was able to observe the behaviour of her breasts through that excuse for nightwear that she was almost wearing. I don't know if it was deliberate or not but as her head bobbed her breasts swung from side to side in time to the movement. I'd have thought they'd move to and fro, rather than side to side, and I couldn't help wondering if that swing was deliberate. I'd never really noticed before just how much Suzy's breasts had grown.

As she worked it dawned on me that while Suzy was priming the pump she wasn't doing enough to get the juices flowing freely. Would this be because she had further use for my poor cock?

"Suzy," I said, finally grabbing her head and lifting it clear. "That nightie or whatever is very nice and if you truly value it you might find it behooves you to put it carefully to one side where it won't get torn into tiny little tatters."

"Don't you dare tear this," she snapped. "I just got it today. Why do I need to take it off?"

"Because it's going to get in the way in a few moments," I pointed out.

"You don't really think I'm going to let you fuck me, do you?" her face shining with innocence. "What do you take me for?"

"I didn't say any such thing. I just felt that I should check to see if you're a virgin before any thought of fucking comes to mind. Once that's been established we can discuss whether fucking is appropriate or not."

"Really? And how do you propose to check my virginity?"

"By taking that nightie off for a start. Then I'll just have you settle on your hands and knees while I kneel behind you and delicately probe. The depth to which I probe should answer the question."

I tapped my erection as I mentioned probing, setting it swaying slightly. Suzy watched it sway and giggled.

"And how far do you think your probe will need to go to be sure?"

"All the way, of course. One must be sure of these things."

Reaching over I put my hands on the neckline of the nightie.

"So, are you going to take it off or do I rip it in half?"

"Don't you dare," she gasped, quickly reaching down for the hem. She had negligee and nightie both up and off in one quick motion, and was now kneeling on the bed naked, breasts quivering slightly.

I placed a hand on her back and gently pushed and she flopped forward onto her hands, her breasts swinging once more. A lot of movement there. I supposed that I'd better hold them still if I was going to fuck her. (Any excuse to get my hands on them.)

I moved around to kneel behind her, losing my pyjama trousers as I did so. One look was all it took to tell me that I needn't worry about foreplay. Her lips were swollen and parted, her inner lips protruding, gleaming with moisture. I brushed the head of my cock up and down her slit a little, letting her natural juices transfer onto my cock. Then I positioned myself and pushed.

I slid smoothly into her, sinking in to my full length in one long smooth stroke, while she made a hissing sound that might have been a yes of approval.

"It would appear that you have lost or mislaid your virginity," I told her. "Seeing that I discovered this fact I feel that it is only proper that I commiserate with you regarding your loss. Perhaps a gentle massage will help."

"Why not," she gasped.

Hands holding her hips I started moving back and forth, my cock rasping against her passage.

"Hey! You said a massage."

"That's what I'm doing, a nice internal massage. You'll find it has some marvellous benefits."

"I just bet it does," she gasped, breathing harder now.

"Of course, I can do an external massage at the same time," I explained, my hands sliding forward to cover her breasts, rubbing them.

I was going to say that things got interesting from that point on, but hell, they'd been interesting from the moment Suzy came into the room. Let's just say that things got a lot more interesting. I don't know who had been teaching her the subtle art of massage but I'd like to give him a commendation for a lesson well taught. Suzy was quite skilled in the art of receiving one.

For her part Suzy seemed to appreciate the skill I brought to the massage, as well. She spent her time urging me on, letting me know when I had to press deeper and when more force was required. It seemed she was getting all knotted up inside and needed a really strong massage, which I did my best to provide.

It seemed that no matter what I did Suzy was just getting more and more tense, and I didn't know what to do. Perhaps some sort of oil would improve the friction. I let loose, supplying the required oil with some gusto, and I'd been right. It was just what she wanted to finish off with. She screamed (or would have if she hadn't jammed her face down into the blankets) and started shaking quite violently, clamping around my cock to ensure that she'd drained all the oil that I'd possessed.

We both collapsed on the bed, muscles completely relaxed.

"You've done that before," I observed, commenting only, not condemning.

"Only once, and that was by accident," she assured me, quite cheerfully lying through her teeth.

"Oddly enough, me to," I assured her. "I was quite shocked by what happened."

"Not as shocked as the girl, I bet," she sniggered.

"Girls, not girl," I corrected and she hit me. Just like that, she hit me for no reason.

"What do you mean girls?" she demanded. "Tell me all. Who were they?"

"A gentleman doesn't tell," I said rather superciliously, standing on my dignity.

"I'm not asking a gentleman. I'm asking you. Now give."
