My Insatiable Lust for Lizzie:

All characters are fictional and over the age of 18.

We slept like that for hours, Lizzie's head on my shoulder while holding hands under the flannel blanket on our laps. It was early in the evening when we were about an hour from home and the last remnants of daylight faded over the countryside.

I remained motionless as I awoke slowly, savoring the feeling of Lizzie's head resting on my shoulder and her hand in mine. The scent of her shampoo was lovely--sweet--almost like honey. I tilted my head towards her so that my nose was almost touching the top of her head. I kept my eyes closed and enjoyed every moment of being close to her.

Her hands were resting on my thighs under the blanket and occasionally would moved just a bit. As the minutes passed and my level of consciousness increased, her right hand was slowly feeling my thighs over my joggers. She continued to slowly let her hand course back and forth over my thighs for several minutes.

I could feel the beginnings of an erection as her hand would get ever closer to my cock with each pass over my thighs. Granted, having mom and dad only a few inches away in the front of the car put a solid damper on my ability to really get hard, though nature was bound to have her way.

Lizzie found the tip of my fledgling boner and abandoned my thighs to help it along. She slowly stroked my expanding rod through my pants until it was tense up against the soft cotton.

I opened my eyes enough to see that my mom was fast asleep in the passenger seat with her mouth agape and an opened book on her lap. My dad was listening to some meaningless talk radio show.

Lizzie picked up her head and carefully put her lips to my right ear. She whispered very softly, breathing into my ear.

"Pull your pants down, big brother," she said continuing to stroke me through my joggers.

I did as she asked, grabbing the waistband and pulling them down just enough for my cock to spring free.

"Very good.....now relax....I'm going to take my time."

Her fingers travelled along my hood and traced the the edge where the tip meets the shaft in a circular motion multiple times before moving to the valley of my opening. Her fingers then moved front to back over the glans. I could barely keep from moaning her name it felt so amazing. Precum started to well up and form in the valley of my tip. She collected it in her palm and coated my tip with my juices. I could imagine my engorged mushroom glazed in precum under the blanket.

Her fingers moved down my shaft, taking in every contour created by my bulging veins, until she reached the tuft of cropped pubic hair at my base. She then began long, slow, strokes up and down as she whispered in my ear.

"I think you like getting jacked off by your little sister with mom and dad just a few inches away, don't you," she asked, kissing my ear.

I could only nod in approval, my body transfixed by her amazing handjob.

She continued to fist pump me as dad listened to talk radio and mom slept, both totally oblivious to the steamy incestuous encounter occurring in their backseat.

Lizzie's head disappeared under the blanket. She was actually going to go down on me in the car! The moment her head slipped below the blanket, my mom snorted and snapped back into consciousness. Lizzie's head re-emerged from under the blanket.

"You kids ok back there?" she asked, peering through the darkness of the backseat.

"Yes, Mom," Lizzie answer. Travis is looking forward to cumming home!" She exaggerated her "u" and her "m's" so that it really sounded like "cumming" and not "coming."

"That's nice, Lizzie. And you're not looking forward to getting back home, dear?" mom asked.

"I guess so. There were just so....so...many good memories made this year in the chalet, Mom." She started to stroke me again.

"Well, there's always next year, Honey. Glad you took in everything!"

"I certainly did! I took in every bit that I could handle."

Mom put her head back on the headrest and appeared to doze off again. In an instant, Lizzie's head was under the blanket. She wasted no time, lavishing my tip with her tongue. She spent about five minutes with her lips and tongue focused on my tip, slathering every drop of precum that greeted her waiting tongue back onto my slick mushroom. Then she started to take my entire length into her mouth. I felt my tip gliding along the inside of her left cheek as I imagined the bulge it created just over over jawline. Then she skillfully guided my tip to the back of my throat until I could feel her lips on the tuft of pubic hair at the base of my shaft.

My hungry for cock little sister then began to slowly stroke my entire 8 inches with her mouth. I heard a soft slurping sound under the blanket as she took my pleasure to new levels. Her fingers tickled my balls as she fucked my cock with her mouth.

I felt my orgasm building fast as she sucked and licked me relentlessly under the blanket. I realized that I had no way of letting her know I was about to cum, so she would just have to swallow my load, which made my impending climax all the more fervent. I reached under the blanket and gently squeezed her right upper arm, hoping that she would get the message that I was about to cum hard into her mouth.

She returned to my tip, knowing that would bring the most intense orgasm. As her tongue brushed against my frenulum, just under the tip, I reached the point of no return. I ejaculated so hard that I swore I could hear my load hit the back of her throat. She moaned and instantly deep throated me, swallowing every wave that I shot into her wanting oral cavity.

I lost control of my muscles momentarily and kicked the back of the driver's seat, prompting my dad to turn down the radio and ask,

"Everything ok, Son?"

"Yes, Dad, sorry, I just woke up from having a dream," I said while emptying my balls into his 18 year-old daughter's mouth.

He turned the radio back up. Lizzie's head slowly emerged from under the blanket. She kissed me long and slow in the darkness and let me taste my own cum as I came down from my orgasm.

She broke our kiss to return her lips to my right ear.

"I think I'm gonna need a shower tonight after this long.....hard car ride. You in, big brother?"

All I could do was nod my head in approval.
