Betrayed

Letting go of her tit I moved my hand down onto the front of her panties and found the crease of her cleft with my index finger. Gently I ran my finger the length of her slit feeling her heat increase the more I rubbed. Breaking the battle our tongues were doing I began to kiss her on the face, and then down to the front of her neck. I could hear her breathing becoming labored as I worked my lips down toward her chest.

Carefully, I used my fingers to slide the leg opening of her panties to one side before sliding my index finger between the folds of her very wet pussy lips. She let out a gasp and laid back onto the seat as my entire finger sank deep into her slick tight opening. Moving it gently in and out I began to finger fuck my sister as I moved my mouth down her body until I was close enough to smell her arousal. With my left hand kneading her breast, my finger stuck into her cunt, I lowered my mouth onto her sensitive clit and started licking her bud feverously. Pulling my finger out of her and using it to keep her panties out of the way, I clamped my mouth over her slit and plunged my tongue up into her hot wet tunnel.

"OOOOOHHHHHHHHH!!" she screamed as her cunt bucked violently against my mouth.

Her loud orgasmic moan snapped me back to reality and I stumbled back away from her. Panic racked my brain as I realized that I had been eating out my own sister. What had come over me I wondered? Cat was still lying on the seat as I gazed into the truck; her panties had slipped back into place but only enough to cover one of her outer pussy lips. The light from the cafes neon sign was bright enough to see my saliva on the exposed puffy one. Slowly, as if in a trance, Cat sat up on the seat and just stared at me.

"God Cat, I'm so, so, sorry. I don't know what came over me," I cried in a trembling voice.

"Let's go home," she said softly, adjusting herself in the seat but not fixing the way her panties were riding between her wet lips.

The ride home was done in silence. I don't think either of us knew what to say. When we pulled up in front of her house she turned to me, placed a hand on the side of my face and kissed my cheek.

"I had a wonderful time. Thanks Jack," she said, then climbed out and went inside.

Her parting words resonated inside my head as I pulled away. At home I found Angie in bed more asleep than awake. She asked where I'd been and seemed relieved when I told her that Cat and I had gone out together.

"That reminds me. Tomorrow's your birthdays and Bill and I have a surprise for both of you," she said sleepily.

"What kind of surprise," I asked.

"Cat will have all you need to know, but you will need to pick her up tomorrow around one o'clock," was all she said before I heard a soft snoring coming from her.

After washing my face I got in bed and tried to spoon Angie. She mumbled something about being tired and scooted further away from me. Par for the coarse I grumbled to myself and rolled onto my back, put my hands behind my head and stared at the ceiling. Every time I closed my eyes and tried to sleep, the image of Cat's puffy outer pussy lip crept into my head. The more I thought about how her cunt had slammed into my face as my tongue worked in and out of her, the harder my cock got. I knew Angie wasn't going to give it up tonight, and I also knew that I wasn't getting any sleep until I relieved my blue balls. Stealthily as possible I got up and headed to the bathroom. Thirteen minutes later I was back in bed and dreaming of how my sister had sounded when she orgasmed.

Angie was nowhere in sight when I woke at eight the next morning. I did find a note taped on the fridge that said she had went into the office early. Sure she did, I thought sarcastically as I drank my first cup of coffee. It was close to nine o'clock, while I was nursing my third cup, when Cat called.

"I need you to get over here right now," she said without so much as a how-do-you do.

"Happy birthday to you too," I said.

"Listen! Just get over here, you won't believe what I have to tell you," she spouted then hung up.

Throwing on a wife-beater tank top, baggy cut-offs and tennis shoes I made it to Cat's house in fifteen minutes flat. She answered the door dressed in a fluffy white full-length robe with a sash tied tightly around her waist. Little Billy was already in school so Cat was alone in the house. We went into the kitchen were she told me to have a seat at the dinning table. After fixing us each a cup of coffee she sat across from me, reached inside the robe and pulled out a pack of cigarettes. I took the one she offered and after lighting up waited for her to say something, fearful that this was about last night.

"Bill and your wife want us to meet them at the Oxnard Inn at one o'clock today," she finally said.

"The Oxnard Inn? Isn't that the motel we saw them..." I didn't finish.

"The very same," she answered.

"Do you know why?"

"All Bill said was that they have a surprise for us," she told me.

"That's what Angie told me last night," I let her know.

"I'm so fucking pissed! Can you imagine the gall of those two? Wanting us to meet them at the same place they're using to fuck each other," she spat.

"We still don't know if that's what they were doing there," I reminded her.

"What else could it be," she said before adding, "And I think you feel it's true also."

"I just don't know Cat," I tried to reason with her.

"You obviously thought so yesterday, or you wouldn't have munched my box like you did," she said with a twinkle in her eyes.

"I really don't know why I did that Cat. Something just came over me and I couldn't stop myself. I truly am sorry for hurting you," I said apologetically.

Standing up she walked to my side of the table and pulled my head to her chest.

"Oh baby brother. You didn't hurt me," she said soothingly.

Turning in my chair so that I was able to put my arms around her waist, I let her stroke my hair while my face nuzzled in-between her breasts.

"What happened last night was special to me. I'm just surprised you didn't finish what you started," Cat whispered in my ear as her hands undid the sash of her robe.

"What are you doing Cat!!" I stammered as she backed up a step and parted the robe.

"What I've been wanting to do since last night," she said.

Stunned, I sat there and watched as the robe slid off her shoulders and landed in a heap at her bare feet. I could not stop my eyes from roaming up and down her tall womanly figure. Her breasts were easily a 36D with a small sag to them from having little Billy. The dark brown areolas were the size of a half dollar capped by small hard nipples. My eyes traveled down over her flat stomach, past her wide hips and came to rest on the small black patch of pubic hair that barely covered her mound.

"Stand up," she commanded me.

Like a robot I stood and remained motionless as she approached. Her eyes remained fixed on mine as her hands deftly undid my pants then lowered them and my boxers down around my ankles, freeing my burgeoning penis. Slowly she sank to her knees, and before I could protest my cock disappeared inside the warmth and wetness of her mouth. I could feel the tip of her tongue caress the underside of my mushroom head each time she pulled her mouth almost off my cock. With one hand holding on to my ass, she used the other one to gently roll my balls around inside their sack. I was becoming delirious with pleasure from the way she was slowly sucking my cock into the depths of her throat. Suddenly she stopped and stood up. Placing her hands on the hem of my shirt she tugged it upwards forcing me to lift my arms before she was able to remove it. Throwing the shirt on the floor, she placed her hands delicately on my hairy chest and forced me backwards.

I figured out what she wanted, so I reached behind me and turned the chair so I could sit leaning back in it. Once my ass landed on the seat she straddled both my thighs and the chair, bringing her soft spongy tits directly into my face. As if my hands had minds of their own they reached up and took hold of both tits while I buried my face between the warm soft flesh. Leaning my head back slightly, I pressed her milky globes together until her nipples were almost touching, then covered both stiff points with my lips.

"Oh yes," she murmured, softly holding the back of my head with both her hands.

The very wrongness of what we were doing only fueled the lust I was feeling at this moment. My cock throbbed and grew harder than I've ever been before, almost to the point of being painful. With one hand on the back of my head pushing my mouth gently forward on her nipples, Cat let her other hand slide down through the hair on my chest before it continued down between our bodies. Moaning softly she reached my twitching member and grasped it tenderly at the base. While holding it upwards between her legs she lowered herself until I felt the puffy outer lips separate and accept the bulbous head of my cock. Lower and lower she sank, until I could feel the smoldering heat of her walls completely surrounding my shaft. Once she was all the way down on me she relaxed her legs, and it felt like I slipped even further into her molten heat.

"Oh shit Jack. You're a lot bigger than I thought you were," she cooed.

With her nipples no longer in my mouth I began lazily raining kisses up and down the side of her neck. The hairs on my chest must have been tickling her nipples because it felt like they had gotten harder all of a sudden. Neither of us moved as she sat there with my raging stiffness buried to the hilt inside her. I could feel her tiny spasms along the length of my cock, causing my pole to twitch erratically against the velvety smoothness of her wet tunnel.

"God Cat, this is so wrong," I protested weakly.

"I know," she replied softly before sinking her teeth gently into the top of my shoulder.

Gently she began rocking her hips forward and backwards, working the head of my penis in small circles inside her cunt. I put my hands on her ass and helped her gyrate on my lap until we had a smooth rhythm established. This went on for at least five minutes before she planted her feet on the floor and lifted up until just the very tip of my cock was lodged between her pussy lips. I almost busted a nut when without warning, she dropped forcefully back down slamming my rod deeply up inside her. She repeated this a couple of times before settling into a leisurely up and down motion. Her fluids coated my shaft and I could feel the air hitting my cock each time she rode upwards.

"Yes...yes...yes..." she repeated with each downward thrust.

"I think I'm gonna cum Cat," I whispered hoarsely.

"Wait for me Jack," she implored, increasing the tempo of her up and down thrusts.

Up and down, up and down. Faster and faster she fucked me, her rock hard nipples scraping against my chest. I tried to match her thrust but wasn't able to, so I did what I could to help my cock penetrate as deeply as possible. The sounds of her rough breathing and the wet sloshing noise coming from our colliding genitalia spurred us on. With her teeth once again digging into my shoulder she forced her cunt roughly up and down on my slickened pole. Grabbing her ass with one hand, and holding her tightly to me with the other, I stood up and swung her over the dining table. With her sitting on the edge of the table she leaned all the way down until she was lying on her back. Spreading her legs by her ankles I began to mercilessly pound into her sopping wet hole. Lying on her back I watched as her tits bounced and jiggled and her lust filled eyes glared at me. Her nostrils flared right before I felt her cunt clamp around my swollen cock. She opened her mouth wide and tried to scream but nothing came out at first. Her juices poured out around my shaft and the slap, slap, slap of my balls on her wet ass echoed off the walls.

"CAAAAAT!!" I bellowed as my spunk shot out and flooded the insides of her convulsing cunt.

"OOOHHHH MYYYY GOD!!" she finally screamed, her orgasm exploding deep inside her.

With labored breath we clung to each other, me gently lying over her with her legs wrapped around my waist holding my softening penis inside her soaked pussy. When my breathing was under control I leaned up enough to look into my sister's eyes. All I saw there was love, the same thing she was seeing in mine.

"Happy birthday little brother," she whispered, with a smile on her glowing face.

"Happy birthday to you big sis," I returned.

For some reason after we untangled ourselves, we became quite shy and hurriedly got dressed. We agreed that I would pick her up in time to reach the motel. After a long shower, I changed and waited till it was time to get Cat. She was waiting and ran out and climbed into the truck as soon as I arrived. When I asked what we were supposed to do when we got there, she showed me a note Bill had left for her. It said we were to go to room 214 and just walk right in. Both of us exchanged puzzled looks before I pulled away and headed to the unknown.

When we got there we went through the lobby and took the stairs to the second floor. Room 214 was down at the end of the hall and we just stood in front of it for a while, working up the nerve to open it. Each of us had thoughts running rampantly through our minds as to what we would see on the other side. None of them pleasant. Cat took my hand in hers as I reached out shakily, turned the knob and pushed the door wide open.

"HAPPY BIRTHDAY!!" four voices rang out in unison.

Both Cat's and my own eyes bulged, and our jaws dropped as we stared into the room. On the left side were Bill and Angie, large smiles plastered to their faces. Directly in the center of the room stood our parents.

As it was explained to us later that evening, Bill and Angie had spent the last couple of weeks setting up all the travel and lodging arrangements for Mom and Dad. Our parents had arrived four days ago and our spouses had spent a lot of time keeping them company until they could spring their surprise on us. Cat and I were speechless, and each time we looked at each other for the rest of the day our faces burned bright red. This was certainly a birthday that my sister and I would never forget.
