After a hitch in the Marines, I returned home to my affluent parents and my only sibling, my sister Diane. My handsome, distinguished father made a good living as an architect. My beautiful mother Connie was an executive in a bank. Her elegant beauty turned heads wherever she went. My sister Diane was a younger version of Mom. Her beautiful face was framed by long blond hair. Dad had paid a fortune in dentist bills to give her a brilliant smile. She had a way of arching her right eyebrow while winking her left eye that drove me wild. The little beauty earned a very good living as a stripper at The Honey Pot Lounge. The Honey Pot was renowned for its beautiful women, and Diane was the cream of the crop.
"When are you going to come and watch me dance, big brother?" she asked.
"Well, I don't know about that. You get completely naked, don't you?"
"Sure. What's the matter? Don't you like girls anymore?"
"Of course I like girls, but you're my sister."
"Don't be silly. You ARE going to come down to The Honey Pot and watch me dance. I insist."
I couldn't refuse my beautiful sister anything, and that evening I sat at The Honey Pot bar and stared up in awe as she strutted her stuff on stage. Her perfect breasts jiggled like Jello as she took long strides on spiked heels up and down the runway. She grinned, winked, and crooked her finger at me. She was dancing just for me and it was working. My cock was so hard it threatened to rip through my zipper. When the little prick-teaser removed her panties and stood above me with her legs spread, I nearly creamed in my pants. I was in a glassy-eyed trance by the time her set ended.
"Well, what did you think, Ray?" she asked, as she slipped onto the stool next to mine.
"You took my breath away, Diane. You are the most beautiful creature that I have ever seen."
"Oh, I bet you say that to all of your sisters. Did you get a hard-on?"
"Well, ah..ah..of..of..c..c..course I did. What man wouldn't?"
I made a dash for the men's room after Diane's second set. I was afraid I would cum in my pants if I didn't take care of pressing business. I took a stall and jacked off in the toilet. The job was finished after only ten strokes. I wasn't the only pervert. The guys in the adjoining stalls were also beating off. Beating off while fantasizing about fucking my sister!
Dad insisted that I take a month of vacation before starting my new job at his architectural firm. The Marines had so thoroughly conditioned me to get up at six that I couldn't sleep past it. My biological clock woke me one morning and I lay in bed trying without success to go back to sleep. I took my morning wood in hand and began to masturbate.
My room was sandwiched between Mom's room and Diane's room. Dad's room was opposite mine on the other side of the hall. As I lay there in bed stroking my cock, I heard what sounded like a soft moan. Thinking it was probably just the wind through the trees, I ignored it and concentrated on my jacking. Then I heard the sound again.
I pressed a water glass to the wall separating my room and Diane's room and put my ear against it. The simple device allowed me to hear every sound in her room with crystal clarity. She was sighing deeply. If the sound I had heard really had been the wind it had been a stroke of good fortune. I assumed that my beautiful sister was masturbating. What I heard next gave me the shock of my life.
"Please, Dad, let's go over to your room. I'm afraid Ray will hear us. I'm not sure I can keep quiet when I cum."
"He won't hear anything, baby. He's sound asleep and the wall is thick. We've really got a nice, juicy fuck going. Let's not stop now."
After that brief exchange, there was a long period of heavy breathing. I had my rock-hard cock in hand and was slowly masturbating. I thought I heard a moan come from the other direction. I pressed the glass to Mom's wall and listened attentively. I heard a soft whirring noise and then the same "mmmmmm" sound that she always made when she took a bite of tasty dessert. I could hardly believe what was happening. My mother was masturbating in her room while her husband was fucking her daughter two rooms away. I didn't know what to do. Which should I listen to?
I returned to my sister's wall and was relieved to hear them still going at it. Diane's moans and sighs were louder and Dad's steady breathing was considerably heavier. He was getting close to the finish line. Hoping to time my orgasm to his, I stroked a little faster.
"Here it comes, baby, are you ready?" he whispered.
"I need a few more seconds, Daddy. Yes, now I'm there. You can let go."
When I heard my Dad grunt, my load shot out onto the floor. I'm sure Diane was cumming, too. It sounded like Dad had his hand over her mouth to muffle her moans. Dad left immediately and that was the end of the show. Then I remembered that this was a double feature. I hurried back to Mom's wall. She was still going at it. Her breathing was heavy and regular. How I wished that I could have watched. I wondered if she had the vibrator inside her pussy or on the outside. I began to pump my still-hard cock. Mom's melodious voice never rose above a whisper. "Oh, yes, oh, yes, oh yesssssssssssssss!" Just as she got her gun, I got mine. Damn, it felt good!
I could hardly believe what had just happened. The entire family had cum together! I had managed to jack off twice in less than five minutes, something I had never done before. I couldn't bear the thought of facing any of them just then. I was afraid that my facial expressions or tone of voice might give me away. After cleaning up the mess, I went back to bed, but there was so much going on in my head that it was impossible to sleep. Then I realized that if Diane was letting Dad fuck her, there was a good chance that she would let me fuck her. That thought hit me like a ton of bricks!
After Mom and Dad went to work, I got dressed and went downstairs for breakfast. As I was munching a bowl of Raisin Bran, I heard the patio door open and close. Diane worked at night, so she and I were usually home alone during the day. Still holding my bowl of cereal in one hand and spoon in the other, I went to the window and looked out on the patio and swimming pool. Diane was stretched out naked on a chaise lounge. As I finished my breakfast, I tried to come up with the best way to hit on my beautiful sister. I decided to play it by ear.
