Part 2
I was sitting in the family room playing a video game and thinking about getting some food when my 15 year old sister, Kim, came in and flopped down on the sectional sofa. She’s a cute kid, just getting a nice figure. With her blond hair and blue eyes, and what were going to be very full breasts combined with long tanned legs, she was going to be a knock out and trouble for all of the boys. But she was still just my sister who I thought of as an annoying brat.

“So, bro, what was going on with you and Julie Lin the other day by the pool?” she said. “You were both in the pool house for a while.”

“Nothing was going on. Just a coincidence. Call of nature. Whatever,” I replied.

“Yeah, right. I saw you walking in there all hunched over. You must have had a real stiffy and when Julie came out she had a glazed look in her eyes and a very satisfied smile.”

“So what. That’s our business.”

“Hah. I wonder what Mom and Dad would say if they knew what you were up to.”

“They’ll never find out unless you rat me out, you little shit.”

“Now is that anyway to speak to your only sister? I might be persuaded to keep quiet, but there’s a price to pay for my silence.”

“What’s going through your evil blackmailing mind,” I asked, getting really mad.

“Calm down. It’s a chance for me to make a little extra money for a good cause,” Kim said. “I need some new clothes for the summer and I’m short of cash. Not too many babysitting jobs lately.”

“What, you want me to pay you to keep quiet?”

“No. Nothing as crude as that. I want to take a picture of your enormous cock and I’ll charge my friends five bucks to have a look at it.”

I was absolutely stunned and could only sputter about child pornography and protest she could really get into trouble. “Are you nuts,” I said.

Kim said, “I’ve got this all thought out and think of the fringe benefits: great publicity for you. Who knows, you might be fighting the girls off.”

That thought stopped me in my tracks. Things were off to a good start with Julie, but who knew how long that would last. It might be nice to have a backup plan.

“OK. Say I was willing to go along with this. What next?”

“If you think about it, you really don’t have much choice. So I just need to take some cock pics.”

“Right here?”

“No dummy. Let’s go upstairs. We’ll use the camera on my iPhone.”

We went upstairs to my room, reluctantly on my part. I sat on the edge of my bed, not knowing what to do next.

“Can you get it hard?” said Kim.

“I don’t know. This is kind of weird,” I replied.

“Let’s give it a try. Take your shorts and underwear off,” said my sister.

I complied and sat back on the bed. In its flaccid state my dick is about six inches long. Kim looked at it and her eyes grew wide. “Wow,” she whistled. “That’s impressive. No wonder Julie looked so happy. Try to make it hard.”

I started stroking, but not much was happening. It got a little bigger, but not a full erection. “This isn’t working,” I said. “You’re my sister for crying out loud.”

“Yes,” she replied, “but I’m also a pretty hot girl too, or so I’m told. Maybe this will help.” In the blink of an eye she pulled her t-shirt over her head exposing surprising large breasts with large coral pink aureoles and nipples that were beginning to stiffen. Then she shrugged out of her shorts and thong and was completely naked. What a sight. My little sister was one really hot slut. She sat on a chair near the bed and spread her legs, giving a good view of her pussy fringed by a few wisps of blond hair.

“What do you think? Does this help?”

By now my head was spinning. Is this really my little sister? When did she grow up into this? They say a cock has no conscience and that must be true. My prick popped to attention, growing to its full 10-inch length.

“That’s what I’m talking about,” said Kim as she grabbed her iPhone and started snapping photos. At one point she reached out and wrapped her hand around my cock. “I just want to feel it,” she said. “Is that OK?”

“I guess,” I stammered. Truth is it felt really, really good and I had completely forgotten that the hand stroking my dick belonged to my sweet little sister.

“What we really need now is a cum shot,” she said. “You keep jerking your cock and watch me.”

Kim leaned back, wet her fingers and slipped two of them into her cunt, fingering herself while at the same time taking pictures with her other hand. If it wasn’t so damn sexy it would be funny. I had some Astroglide in my dresser drawer, a necessity for my career as a serial masturbator. I squirted some into my hand, lubed up my cock and kept pumping away.

Watching my sister pleasure herself was all the stimulation I needed. “Get ready,” I warned her and soon I was spurting cum halfway up my chest and all over my stomach and hands while Kim clicked away taking photos. As my eruptions slowed she dropped the camera and caressing her breasts with one hand, continued to work on her pussy with the other. Soon her orgasms hit and she went into spasms too, panting and moaning.

As we lay there spent, me on the bed and her sprawled in the chair we began to giggle and soon were laughing uncontrollably. “Well this is a whole new dimension in our brother-sister relationship,” I said. “Yes,” Kim laughed. “This could be the beginning of a great business partnership too.”

Kim came over and sat beside me on the bed. She rubbed her finger in the cum drying on my stomach. “It’s very slippery and there was so much of it,” she said. “Do you always cum like that?” “Yes,” I said with a shrug. “I seem to shoot quite a lot every time. Just lucky I guess.”

“I wonder what it would feel like going up inside me,” she said. “I bet it feels really warm and good.”

“Whoa, let’s not go there,” I exclaimed. “You are my sister and doing what we just did is far enough.”

“Why not?” Kim reasoned. “I’ve been on the pill for two years and if you’re going to have sex for the first time, why not with someone you trust, like my brother. Besides, I doubt if any of the boys around here have a cock like this.” As she said that she reached over and began playing with my prick, fondling it and gently stroking it. And the damn thing began to get big again. Like I said, no conscience. She climbed over me and straddled me, with her damp pussy on my balls and lower part of my cock. She continued to stroke my prick and cooing, “Do you like that?” By now I was completely helpless and too far gone to stop her.

My sister leaned forward, shoving her breasts into my face and commanded me to suck her tits. I complied with eagerness, licking and slurping away. She wriggled and gasped and slid her pussy up and down my cock shaft. She was getting very wet and her cunt sliding up and down my dick drove me crazy. After a few minutes of this she raised up and started teasing her cunt lips with the head of my cock. Slowly she lowered herself on my prick, just slipping the head inside her vaginal lips. Little by little she slid my cock into her, inch by inch until about four inches were in her. I was careful not to thrust up, letting her take the lead. This went on for a while and it’s a good thing I had already shot a load because I would not have lasted long otherwise.

Kim was shaking a bit so I suggested that she lie on her back so it would be easier for her. I got between her legs and used my cock to rub her clit while I leaned forward to lick her tits. She seemed to be getting even wetter so I slowly inserted my cock into her very slippery cunt. I was in about six inches and thrusting in and out very slowly. I could tell this was driving her wild and she tossed her head back and forth and groaned in ecstasy. Suddenly she grasped my ass with both of her hands and pushed her hips up into me. My cock slid in almost all the way and she cried out in pain. I caressed her, kissing her face, lips, eyes, all over, quieting her down as she lay there panting.

“I’m OK. It’s better now,” she said and began to slowly move her hips up and down and I pulled out and then slid back in using a slow rhythm. The tempo picked up and by now my cock was fully embedded in her. I could feel her clit grinding against the shaft of my cock and knew it was just what she wanted. Soon we were fucking faster and faster. Kim was shaking like a leaf and flushed all over. She bucked once or twice as her orgasm began, moaning and thrashing on the bed as my weight held her down. Wave after wave, it seemed like she would never stop. As one spasm ended she would urge me to pump her some more and another would hit. I lost count.
Soon she quieted and asked, “Did you cum?” “Not yet,” I replied. She begged me to cum in her and I didn’t need further encouragement. I started moving in and out of her, feeling her warm cunt gripping my shaft as I pushed into her. In just a few minutes I was close and I began to shoot into her, pulse after pulse of hot semen. Kim wrapped her legs around me and used her heels to push against my ass cheeks forcing me deeper into her. I could feel the cum bubbling out around my shaft and running down her ass crack. She was crying with pleasure now and soon we were lying in each other’s arms, completely worn out.

Resting on my elbows to keep my weight off her I slowly slid my cock in and out of her dripping pussy. My mind was racing all over the place. What had I just done? Fucked my baby sister, that’s what! And probably ruined the bed spread too. Kim had her legs wrapped around my waist and her arms around my neck and sighed, “That was better than I thought it would be. I can’t wait to do it again.”

OK – that was something I hadn’t anticipated. “Kim, this was great and you’re a great fuck, but I don’t think we should make a habit of this. If Mom or Dad ever found out we’d be dead.”

“Don’t worry,” she said. “We’ll be extra careful. You can’t believe that we can live in this house together with a world class cock just steps away. And I’ll bet you won’t be able to keep your hands off of me either.”

She had me pegged there. I was hooked on pussy and knew I couldn’t resist. Not only did I have a business partner, I had a fuck buddy too.”

“You may be right,” I admitted. “Good, I knew you’d see things my way,” she said. “Now, do you think you can get hard again?”
