Creating Online Sex Games

My stepbrother and I started having sex several months ago. We are both in our mid-twenties and are not in a serious relationship. We live with our parents. I tend not to wear a lot of clothes around the house. Our parents had only married a year ago. Before, me being half naked was not a problem. It was just my mom and me. Now, I should probably wear more clothes.

I'm not really sure how it first happened, but I liked it. Jerome has a pretty big dick. And unlike a lot of guys who have a big dick, he knew how to use it. He always made sure I came at least once before he did, often twice. And when he unloaded his cum in my pussy, I always came.

So, well, fuck your stepbrother. I guess I have made some moral compromises.

He often played this stupid game with my nephew's stuffed toys, as if they wanted to have sex, not him. I kept telling him to stop it and just ask if I wanted to fuck. I guess he thought he was funny. Men's frontal cortex doesn't evolve until they are in their late 20s. Jerome was 22.

I really like fucking Jerome. (Everyone else calls him Jerry. But that makes me think of old Jerry Lewis movies. If I'm going to fuck him, I can't have that image in my head.) And as much as I like fucking him, this is never going to be one of those strange, fall-in-love-with-your-stepbrother, live happily after Hallmark stories. I like Jerome. I really like his dick. But it's not forever. As for Jerome, I think his vision of the future is his next paycheck.

I should describe myself. I'm about 5' tall and weigh 95 pounds. I have very tiny tits, so I never wear a bra. I keep my pussy bald with regular Brazilian waxes. Jerome seems to think it's fascinating. It's just a vagina. But I do it for myself, really. I like seeing the mounds and the wings that my pussy lips look like when they emerge. I often use a mirror to admire myself.

I actually don't care about what anyone else thinks about my pussy. I love her.

I also really, really love my tits. They are tiny, but their nipples are extraordinary. I can cum from tit play.

I have blonde, shoulder-length, very curly hair. My voice is still a little girlish, so I am often not taken seriously. I hate that. I think I'm going to hire a voice coach to try to change that, even though it sometimes pays to be underestimated.

I'm super-smart, but not very many people see that, which is okay. I work for a start-up video game design firm. I love video games. I've played them all my life. I always beat my older brothers. I am proud of participating in the creation of some great games that are really challenging and everyone knows. I'm also working independently on a game of my own that I think will be incredibly successful.

One afternoon, I was in the living room wearing just a camisole and thong underwear and working on my concept.

Jerome came in and started his thing with the toys. Finally, I stood, took off my thong and peeled off my camisole.

"Get rid of the plushies. I'm working on my game concept, but if you want to fuck me, that's okay. I'll still work on my game," I said.

"Sure, sis, you can play your game while I fuck you. You don't think it will mess with your game?" he asked.

"It probably will, but let's try," I answered.

As he eased his dick into my pussy, I took a breath. His cock is so good. I was sure my work would be interrupted.

But I kept working. A lot of game design is writing code. Even though it can be kind of boring, I'm not trusting AI with my concept. After a bit, with Jerome's cock sliding in and out of my vagina, I developed a kind of rhythm. Code, thrust; code, thrust.

I'm not sure how his dick knew where my G-Spot was, but that cock kept banging into it. Finally, I had to throw the keyboard aside and just fuck. He was really good.

I don't scream during sex or when I cum. I've been told that I make quiet sounds like, "He, he, oh, oh." Apparently, when I cum, I say things like, "Shit, shit, shit, ugh, ugh."

I have no idea. All I know is that Jerome pumped my pussy and filled it with his cum and gave me about three orgasms.

God, I love sex.

After a while, when we relaxed, he asked, "What's so great about playing this game that it can distract you from fucking?"

"Stupid. I'm not playing a game. I'm creating a game," I answered.

"While I am fucking you?"

"Well, granted, the fucking slows down my coding. But I really like it, the fucking, I mean. Well, the coding too. Sometimes it's hard to do both at the same time. Your cock pounding my pussy is really sort of distracting," I answered.

Jerome was not the brightest bulb on the porch, but that made him smile.

"So, let me get this right. You like me pounding your pussy the full length of my cock buried completely. But, while we are fucking, you aren't playing a game, you are creating one?" he asked.

"Bingo. But my work is much more efficient when you are not fucking me," I answered. "Your wonderful cock pounding my pussy is really distracting. But sometimes the rhythm of your thrusts matches my codes. Other times, I just have to fuck you. In case you haven't figured it out yet, I really like fucking you."

"You are crazy. And I really like fucking you. You are an incredible lover. But what is this game you are making?" he asked.

"It's an online sex game," I answered.

All he said was, "Dude."

I'm sitting on the couch, nude, hard nipples on tiny tits, his jizz dripping out of my pussy, he has fucked me from here to tomorrow, and all he could say was, "Dude."

"How does it work?" he asked.

"It's an RPG. You play the role of a sexy young woman. Okay, it's me. You are really horney. You have to choose who and how you want to fuck. Some of the characters might not want to fuck you, so you try to convince them one way or another. Others may be overly enthusiastic, and you have to curb their enthusiasm so you can get fucked the way you want to be. The goal of the game is to fuck -- a lot. You score by orgasms. Your orgasms score more points than your partners, although theirs score as well."

"You can have sex with just one partner or multiple partners," I continued. "You can choose the gender(s) of your participants. You can choose any position or even make up your own."

"Wow, sis, that's a lot," he said.

"That's not nearly all, dude," I said, the sarcasm flying over his head. "You can also choose the race of your partner(s). And I'm working on fantasy characters. My first one was this green dude, not terribly attractive, but he has two dicks. He can fuck you in the pussy and the ass at the same time, or he can fuck you and another partner at the same time. A favorite is Tinker Belle. You can choose TB's gender, so she can be that beautiful winged fairy that we grew up with, but she can have a pussy or a dick. I've made a few fairy and wizard characters. My latest is a giant, fire-breathing dragon with a massive cock that you've got to figure out how to stuff into your normal-sized pussy. And if you have him go down on you, you have to make sure his breath doesn't burn your clit."

"That all sounds fantastic, sis. But can you make the player a dude?" A surprisingly intelligent question coming from him.

"That's probably going to come in a later version. For now, I know a whole lot more about women's fantasies than men's. And I think women are a greatly underserved part of the market. But you are right, if I had a male main character, players could potentially have virtual sex," I answered.

"Sis, you are going to make a million bucks off of this," he said.

"Bro, I think the game will make a lot of money. But I have a very special part of the package. Do you know what a sybian is?" I asked.

"No idea," he answered.

We were both still completely nude and step-bro was manifesting an ever-enlarging hard-on. "Grab our clothes and follow me into my room. You are about to receive an education."

We went to my room, and out of the closet, I pulled my sybian, set it on the floor, and plugged it in.

"What the hell is that?" Jerome asked.

"It is a sophisticated sex toy for women, and I guess for gay men as well," I answered.

It kind of looks like a saddle, but it doesn't have the horn at the front or the cantle (the high bit at the back). In the middle is a phallus -- an artificial penis. It's about six inches in length, anatomically correct with a head and veins throughout.

"I wanted to get mine a replica of your penis, but that was incredibly expensive," I said. I took up the remote, which was wired, to show him what it did. It vibrated. It wound in small circles. With the remote, the user could alter the speed of vibration and the revolutions.

"I have made some additions to the off-the-shelf machine. I hope that it will be different enough that I can secure copyright protection. I've added thrusting, so the penis moves up and down along with the other movements. It's just a solenoid. I have no idea why it wasn't originally built in. I suppose because the original inventors were men. I've also added a pivot for the phallus. That way, if the user leans forward, the phallus moves with her. It can't quite be like dog-style because of geometry, but it's close. Likewise, if the user leans back, the phallus follows her vagina, as an actual penis would.

"I have added another special control. And this is all you, Jerome. It's the pulse of your dick as you shoot your cum deep inside my pussy." I adjusted the control and we watched as the phallus pulsed longer and wider in a kind of rhythm.

"That's what it feels like when I cum inside you?" he asked.

"Pretty much. I've tried it out a couple of times," I answered.

"Would you try it out for me? I'd love to see this machine fuck you," he stated.

I knelt over the phallus. Normally, I would have had to lube up in some way. But all of this talk about sex and seeing Jerome's erect cock, I was already wet. I eased my pussy down over the phallus. Once it was deep in me, I intensified the vibration and made the cock swirl inside me.

I had done this before, but never with someone watching me. The more Jerome stared at my pussy and my tits, the hotter I got.

Then something happened that I hadn't considered. Jerome started masturbating as he watched me. He kept stroking his penis as he watched me fucking this machine. His cock got incredibly hard and long. I actually salivated.

As the machine dragged me to orgasm, I watched his hard dick getting close to orgasm.

"Bro, cumin my mouth!" I cried. Just when I reached my peak, so did he. He put his cock up to my mouth, and I took just the head between my lips and tongued the tip. He released spurt after spurt. I didn't swallow just yet, but there was so much cum that it dribbled down my chin. At that point my own orgasm rippled through my body. I opened my mouth so he could see his cum there. Then I swallowed.

"Fuck, sis, you are amazing!"

I slid off of the machine and leaned against him for a while.

After a bit, he asked another intelligent question, which surprised me once again.

"Sis, your video game is amazing. And the modifications you have made to the machine seem like a winner. But I don't understand the connection between the two."

"Wow, Jerome, you have hit on the key to the success of this project. I'm impressed," I said.

"See, I think good stuff sometimes," he said proudly. I just smiled at him and appreciated his simplicity.

"This is the key. I have built Bluetooth into my sybian. It can connect to the game. So whatever sex act the user chooses, she can feel it in her vagina via the machine," I said. "That's what I was working on when you interrupted me with your big dick and fucking."

"Oh no, did I ruin things?" he asked, concerned.

"No, buddy. It is probably going to take me several weeks to incorporate all of this. Even though I have bought the best chips, and I am on my best programming game, it won't be perfect for a while. I'm looking at a year of trial and error before it's even in Beta testing," I answered.

I noticed his dick was getting hard again.

"So, are you going to be doing this trial and error? Does that mean you will be riding the machine while you play your game?" he asked.

"Well, for the most part, yes," I replied.

"Anytime you need an independent observer, just say the word. And what is Beta testing?" he asked.

"That's when I think the product is virtually ready for market, I will ask a select group of people to try it out and give me their opinions. They might see things I, as creator, might not have taken into account," I said.

"So, there will be a room full of women playing the game and riding your machine? I'd like to see that," he was almost salivating.

"No, actually. They will probably come here and use it in private, one at a time," I said.

"Darn, I had a vivid mental image," he said. I laughed.

After some thought, he said, "You are developing an amazing system. It's going to be crazy successful. You'll make millions. But, if you could make it for a man, you would be a billionaire."

"I'm working on it. The sybian has a pad in front of the phallus with lots of little soft points sticking up. It's tied into the vibration control. I think it's for clit stimulation, although I haven't used it. I have you for that," I said, and he actually blushed. "I have been thinking of putting a vagina behind the phallus, mostly for pussy-to-pussy contact, while keeping the clit rake," I continued. "Of course, when I do introduce the game for men, that's where he would insert his penis, or maybe in the back, or both, I don't know."

"You can do that?" he asked.

"Yes, I think so. It is all going to take a lot of time. If the first introduction is successful, I'll quit my job and work on this exclusively. If not, I already have a good job." I said. "Hey, when I get to the male part of the game, would you help? I mean, you're a guy, and I know you do sex very well."

"Of course, I'll help. I assume there will be a lot of fucking as you develop your game. I'm your guy," he said proudly. "But, how do you know about how to connect all of this together? I mean, it seems very complicated," he asked.

"Remember that I was a computer systems major and an electronics engineering minor. I like toying with electronic systems. I can make all of this stuff happen, as long as I can keep it all in line in my head," I said. "I know I come across as a dizzy blonde who just wants to fuck, but I am smart."

Jerome is a simple man. "I've always known that you are crazy smart. That is so sexy. Can we fuck again?"

My mind said, "Yes, fuck me as deep and as hard as you can," but my voice said, "Yes, of course."

I spread my pussy lips.
