Getting Even

"Holy shit Sis," I breathed.

"I'm cumming. I'm cumming" she cried.

She continued to spasm on top of me over and over again. It was either one long orgasm or a whole bunch of them, I wasn't sure. She wrapped her legs tight around my back, forcing me deep inside her. Courtney's cunt squeezed my trapped cock as she continued to spasm, making me lose control. I came deep inside my sister, sending her screaming with a mind-blowing orgasm of her own.

We sat on that chair for a while, completely entangled, my cock slowly losing its rigidity inside her. She leaned down and kissed me, softly, gently, like a lover and pulled herself upright. Gravity took hold and the mixture of our juices ran slowly down her leg. I stood up with her and took her hands into my own.

"I don't want this to end," she said softly, her voice cracking. There were tears in her eyes.

I stroked her cheek gently, and she met my eyes, smiling. "No one has to know," I said.

"No one has to know," she repeated tenderly.

By now we were both in dire need of a shower. I gallantly offered to let her go first, but she insisted that we go together. Courtney can be so thoughtful. And yes, we ended up fucking in the shower. And in bed a few hours later. There was a lot of sex that first couple of days. Making up for lost time I guess.

We stayed in till late in the morning the next day. We got caught up, talking about work, school, sports, exes, whatever came to mind. It was funny. Despite the fact that she was laying next to me naked, Courtney was still my sister. I still thought of her that way. I guess we were just a little more affectionate than most siblings. That's why it wasn't weird at all when I said, "I love you."

Courtney smiled, "I love you too Kiddo."

"You know I hate it when you call me that," I whined.

"Liar," she giggled, leaning in to kiss me.

We didn't think keeping our tryst a secret would be too difficult. Our folks lived on the other side of the country, we didn't have the same social circles, and as half-siblings, we didn't look similar enough to cause suspicion. There was one thing I didn't count on though. I got up to make coffee while Courtney searched through my closet for a shirt to wear. I turned to find my front door wide open and an overly excited Charlie standing in the frame.

"Dude! I've been calling you all day. We were supposed to have lunch at Hooter's today, remember?"

"First of all, I never agreed to Hooter's Sunday. Second of all, knock first!" I yelled.

"Calm down Danny-boy, nothing to get your panties in a bind about. Unless," Charlie trailed off. His eye caught the discarded skirt. "Danny-boy, you got some last night. Atta-boy!"

"Charlie, seriously, get out of here," I said, panicking. Just my luck, the one guy in the entire west coast that could connect Courtney to me was the first to show up at my door.

"Is she hot? Where's she from? Has she ever done a devil's three-way?"

"Get out!" I hollered.

"Dan? Is someone here," Courtney asked as she walked into the living room in an old T-shirt.

Charlie was, for the first time in his life, speechless. His eyes darted back from Courtney to me. Courtney was equally horrified; I'd given her the heads up on Charlie just an hour ago. Finally, Charlie resumed breathing and spoke.

"This is, without a doubt, the greatest moment of my life," Charlie said dramatically.

"Charlie, this isn't what it looks like," I said, making a vain attempt to lie.

"You fucked your sister!" Charlie shouted with glee.

Courtney didn't speak. She just stood there, with her mouth agape for a while.

"You cannot tell anyone," I growled.

"Tell people? Why would I tell people? I've got leverage on you for life Danny-boy," Charlie grinned. "Seriously though. You kids have a great day." With that, he headed for the door.

Courtney and I just stood there for a while. Once again, I had no idea what to say. Finally, she spoke up.

"He won't tell anyone, will he?" she asked, scared.

"No. He won't," I answered. "The fun he'll get from holding this over my head will be far greater than any he'd get from telling someone. Besides, I'm pretty much the only guy that can stand him, and he knows that. This just means I'm going to be spending a lot more time at strip clubs. I better ask for a raise."

"Well, at least you'll get to come see me at work," Courtney joked.

"I think I'll be able to live with that," I chuckled.

"I love you," she said warmly.

"I love you too Sis," I replied.

As I predicted, I ended up losing a great deal of sleep playing wing-man for Charlie. About once a week we'd drop by Centerfold. It became kind of a running joke, for him anyway. One benefit was that Courtney and I could be pretty open as a couple. Charlie just thought it was funny.

A few weeks and a few dozen boxes of ramen later, inspiration came knocking at my door in the form of Monica, Charlie's pregnant cousin. That's right. Charlie hadn't stopped at getting her number. No wonder the whole incest thing hadn't creeped him out. She'd been having a hard time getting in touch with him, but she heard that we were friends and decided to stop by. Suddenly, I had an idea.

Monica, Courtney, and I formed a coalition devoted to a single task. The project was called www.isthisyourbabydaddy.com. It was a site similar to MySpace or Facebook, only it was intended to help women that had gotten knocked up by strangers track down their AWOL sperm donors. In less than a months, the site has several thousand members. You won't believe how many hits Charlie got. That guy must really hate condoms.

I did him a courtesy though. The majority of men on the site came with personal information, including full name, current address and phone number. We didn't post any information on Charlie, at least for the moment. Once Charlie's match count started to approach triple digits, we decided to send him a link to his page.

The next day, Courtney and I were watching a movie at home when a red-faced Charlie burst through my door.

"Seriously dude, knock," I said. "We have sex in here."

"Is this your baby daddy dot com!?" Charlie sputtered.

"Yeah, your cousin and I thought it would be a great community service project. What do you think?" I asked innocently.

"Monica! You! Aaaarrrgghhh!!" he choked.

"Oh, thanks for knocking her up for us by the way," Courtney added. "We'd never had sex with a pregnant girl before. Plus, Danny-boy hates condoms."

"Now, as much as I love strip clubs, I think I'm going to be pretty busy for a while. My sister and I have a lot to do at home," I said, winking at Courtney.

"Oh, and call Monica," Courtney added. "She's looking forward to hearing from you."

"Yeah, we really worked hard on that site. We'd hate to have to add to it," I quipped.

"And wear a damn rubber!" Courtney and I finished together.

Charlie stood in silence, his head hanging low. He turned towards the door and slowly pulled it open.

"Oh, and Charlie," I added as he stepped out.

"Yes," he hissed.

"Now we're even," I declared with finality. He left.

My sister and I burst into hysterics as he left. As the laughter faded, I reached for the phone.

"You can call Monica later," Courtney said as she swatted it out of my hand. "After all, I still haven't given you your birthday present."

"I dunno Sis. That's going to be pretty tough to top."

"Wait and see," she replied as she put her own phone away. Had she been texting someone? Suddenly there was a knock at the door. "I'll get it," she said quickly.

A familiar looking redhead stepped through the front door clad in a pink robe. Courtney greeted her with a deep, sensual kiss. Once they broke it, the two women turned to face me.

"Well?" Courtney asked. "Aren't you going to open your present?"

I smiled and untied Julia's robe while Courtney kissed the back of her neck. Not long after I was balls deep in Julia's tight hairless cunt. It was almost like I was fucking them both. Each time I drove into the nimble girl's pussy, her long tongue probed deeper into Courtney's waiting snatch. Eventually I blew yet another load deep into my sister's womb as her friend sat nearby fingering herself feverishly. And as the three of us rode the final throes of our orgasms, I remembered just how lucky I was to have Courtney as a sister.
