Desc: Sex Story: My experiences with a pair of twins. One of them was crazy. But which one?

Happy New Year! Let’s get right to it. A lot of you didn’t like Two Bullets. And a lot of you did. The letters I got were pretty much evenly divided. I want to thank everyone who wrote to me. I’d like to especially thank the peopl who took their time to sit down and write to tell me what they didn’t like about the story. In most cases they seemed to see the same things. First, the story was simply too dark. And there was no lght at the end of the tunnel. There was also no charcter that was truly moral in the story to root for. I’ve noted that and will attempt not to make similar mistakes in the future. And now to this one. There is a happy ending this time, but there are also a couple of twists along the way. Thanks as usual to the great Barney-R for editing it. I’m not sure whether I should mention this or not but he has an awesome story on the way too. Amyway here we go. SS06


“I don’t hear anything,” screamed my wife from outside of the door. I shrugged and looked at the woman sitting on the bed beside me.

She was naked and so was I. I wasn’t ogling her boobs, although I knew how awesome they were. I was pretty sure I knew what they felt like, even though I had never touched them.

“Give us some God damned time!” she screamed back at my wife, in almost the exact same tone and timber.

She stood up and positioned herself in front of me. Her body was thin and toned, but she didn’t work at it, her breasts were perfect for her form. They jutted away from her rib cage and stood out like two melons grafted onto her torso.

Her waist was narrow and her slim hips belled out into a very nice ass. She turned away from me and shook that ass a little bit. Then faced me and cupped her breasts.

Almost any other man in the world would already be fucking her and she knew it.

Her mouth formed a frown. “You really don’t want to do this ... Do you?” she asked sitting down beside me again.

I shook my head and looked down. Even though I was trying to remain emotionless, a solitary tear rolled down my cheek.

“Alan ... You don’t think I’m sexy?” she asked. I nodded my head and she saw the tear.

She wrapped her arms around me and hugged me. She felt warm and soft and ... Amazing.

“Then ... what’s the problem, Honey?” she asked. “Don’t you want to make a baby?”

“Callie ... I want to be a father,” I said. “I think I’m ready. I think I’ll be a good one ... But...”

“But what?” she asked.

“But I keep thinking about what this will do to you,” I said. “I keep thinking that this is too big a sacrifice. And I know that you won’t enjoy it.”

She smiled and a tear on her face matched mine. “Callie...” I said.

She raised her face and looked at me.

“Callie ... I ... I know you don’t like me. I mean I know why and you have a really good reason ... But I...” I mumbled.

“But what, Alan,” she asked.

“Callie ... I love you,” I said. “I just can’t do anything to you that might hurt you or cause you any...”

She hugged me again. Then she shook her head. “Alan you’re a special guy,” she said. “My sister has no idea how lucky she is. Look ... what we’re doing is a very important thing for our family. Not just for you and Kellie, but for my mom and dad and for your parents too. Shit ... it’s even important for me.

After Kellie’s accident ... You can’t imagine how much pressure my parents have put on me. And I’ll tell you something else ... Alan, if there was any man alive that I would let do this to me ... It would be you.

I love you too. You’re the best brother in law a girl could ask for. Now we both agreed to this ... So let’s get it done.”

She pushed me down onto the bed and took my shrunken dick in her hands. She gently rubbed it and then ran her tongue along the length of the shaft.

“Callie, you don’t have to...” I began, even as my dick began to inflate.

“Sssshhhh,” she smiled. She gently blew into the hole in my helmet sending me into spasms.

“Where’d you learn how to...” I gushed, as the waves of pleasure ran through my body.

“We’ll talk someday,” she said.

I rolled out of her grasp and buried my head between her legs. She had absolutely no hair on her pubes and a gold ring through her labia.

I flicked the ring with my tongue and was rewarded with a gush of juice and a scream. My tongue flicked the ring against her clit several more times in succession and her legs lolled open. She hunched her pussy against my face like there was no tomorrow.

She pulled me up her body until we were face to face. She licked my face to get a taste of herself and we made eye contact. I swear something passed between us. But I was probably just reading something into the situation that wasn’t there.

While I was thinking, Callie was working, though. She lined my dick up with her opening and then held it there with one hand while the other grabbed my left ass cheek and pulled me inside of her.

Despite the fact that Callie was nearly thirty years old, she was as tight as a teen-ager. That was something that Kellie couldn’t claim. I had to push and push really hard to get the rest of my dick into her.

But Jeezus once it was there, it felt as if lightning had struck me. Suddenly all of my reservations evaporated. Callie was clearly feeling it too. She was making the same keening and moaning sounds that Kellie made and surprisingly she hunched her pussy against me as if she was enjoying it.

I hooked my arms through hers drawing us closer together and suddenly we were fucking like there was no tomorrow. My arms were busy rubbing her back. Kellie loved that so I assumed that Callie would too. And she did.

I leaned forward, riding her high. Every stroke we took put pressure on her clit. “Oh Jeezus fuck me,” she hissed. “Fuck that pussy!”

“It’s so tight,” I gushed. She smiled at that.

I have no memory of who started it, but suddenly we were kissing. We made eye contact and both silently acknowledged that we had crossed a line.

I couldn’t look into her eyes, knowing that we had broken a rule, so I switched positions and got behind her. I started slamming my dick into her from behind. I reached forward and gave her breasts the attention they deserved while she moaned and pushed her ass against me.

The buildup was too intense for me. My balls were screaming for release. I reached under her and rubbed her tummy. She suddenly froze and screamed. Half a second later, I emptied my balls into her thirsty vagina.

We were both spent, we lay side by side on the sweat covered sheet and again something passed between us.

“What the fuck was that?” she asked. I looked at her in confusion.

“That belly rubbing thing you did?” she accused.

“I ... I...” I sputtered.

“Allen you’re not supposed to be making love to me,” she whispered. “This is just supposed to be a quick, nasty fuck to knock me up. That felt...”

Before she could finish her sentence the door opened and my wife Kellie marched in and sat on the bed.

“Are you done?” she asked excitedly. “I brought you guys a drink and a snack. I think you should rest and then do it again.”

“I don’t think so,” I said. “This isn’t right.”

“What the fuck are you talking about?” Kellie asked angrily. “This is her most fertile time. You need to keep fucking her until the window closes. I don’t care if you fuck her three or four times a day. We need to get this done.”

Kellie looked at me as if she wanted to kill me. Surprisingly, Callie came to my aid.

“Kell, this was kind of hard on me too,” she said. “I’m not used to doing it with ... MEN. I’m already kind of sore. Maybe we need to ease into this. We’re lucky we were even able to do it once. And he did kind of ... Get it done. I mean we got the parts inserted where they go. And he shot a lot of his stuff inside of me...”

“You just don’t want to do it anymore either,” said Kellie angrily.

I got up and headed for the shower with Kellie glaring at me. Callie started to get up and Kellie pushed her down onto her back.

“Tilt your pelvis up, Sis,” she said. “That will keep the sperm inside of you and give us a better chance of finding an egg. You need to stay that way for a while.”

I stormed out of the bathroom, still slightly wet and pulled on boxers, jeans and a sweatshirt. I jammed my feet into a pair of loafers with no socks and grabbed wallet and keys from the dresser.

“Honey!” whined Kellie.

I looked across the room at Callie who was on her back, with her ass off of the bed. She was swinging her hips from side to side as if she was trying to mix our sperm and egg cocktail.

I felt as if she was trying to somehow send me a silent message as I left.

Three minutes later, I was pulling my glass black 2014 Mustang GT out of the garage and roaring away down our street. Somehow I knew my life was different.


Kellie

“Damn that thing is loud,” my sister Callie exclaimed.

“Can you believe he paid even more money for a louder exhaust system?” I smirked. “Men make no sense. I thought the idea was for the exhaust system to make the car quieter. You remember all of those descriptions of cars that purr like a cat? I’ll be glad when all of the cars are electric.”

“Kellie, you were treating him like shit,” she said. “He really doesn’t deserve it.”
