"How long till we get there?" I called from the back seat.
"Mmm... About another two hours," My dad replied, taking a quick glance at the map on his GPS.
"Do you need something, honey?" My mother called from beside him, smiling at me through the rearview mirror.
"Nah, I'm just asking," I leaned back in my seat and looked out the window. We were on a road trip, heading to a beach resort for vacation.
My name is Logan. I'm eighteen years old and had recently graduated from high school. I stood around 5 feet 9 inches in height, with a lean musculature. My hair was a dusty brown, wild and unkempt, and my eyes were a deep blue. I wore a pair of red swim trunks and sandals, with a colorful buttoned shirt on top.
"You asked like half an hour ago," My sister poked me in the ribs. I looked over at her, arching an eyebrow in annoyance. She giggled at me and stuck out her tongue.
Lola was twenty and attended the university I had applied to. She was a part of the women's volleyball team and was extremely popular. She was the same height as me, with a toned, attractive body. She had smooth, glittering skin with dirty blonde hair and bright blue eyes. She wore a stunning yellow sundress that barely came past her wide hips and round ass, revealing her long sexy legs. The v-neck showed off the gorgeous top cleavage of her boobs, and her hair was done in a bun.
I would normally lie and say that I didn't one bit think of her in a sexual way, but a recent curve of development in our relationship has changed the way I see my sister. She was indeed a sexy item that any man, including I, would be lusting after. I knew a lot of the boys at my school, including my best friends, wanted a piece of her, but she never once had a boyfriend, nor did she ever intend to.
"Come on, Log," She placed a hand on my bare knee and rubbed it softly, "Don't get so anxious. Just relax."
'Log' was a nickname of mine that she would call me by, and some of my friends picked up on it. It seemed like a funny way of shortening my name, and people took to it as a way to tease me in a friendly manner. My sister, on the other hand, had an entirely different reason why she referred to me in that name.
"My body feels like it's about to fall asleep," I complained to her, "Especially my lower half, considering how long we've been sitting in here for."
"I'm sorry bud," My dad called to me, "But you'll have to wait a bit longer. Maybe you could lay down and stretch your legs out... If Lola is alright with that."
"I'm alright with whatever," Lola shrugged, smiling over at my dad, "As long as I get a chance to relieve myself too."
Her hand slowly slid up from my knee, pushing the legging of my trunks back to reveal my slightly hairy thigh. She rubbed it softly, the sensation of her smooth hand sending tingles throughout my body. The corner of my mouth pulled up slightly as she and I exchanged looks.
"Yeah, I'm down to let you have your way," I told her, my eyes flying down to stare at her sexy, glistening thighs, "As long as you give me what I want."
My hand, which lay on the seat in the small space between us, began to slowly slide over to her legs. As my fingers gently brushed against the side of her thighs, her hand slid up even more, this time going over my shorts and stopping on my crotch. She grinned at me, her eyes glittering as she licked her lips. My cock began to tent in my trunks, just below her pretty hand.
"Deal," She murmured. Our parents were oblivious to our subtle messages.
While mom read an article from her phone and dad paid attention to the road, I caressed my sister's thigh. I ran my hand down and up the length of her gorgeous upper leg, feeling the smooth and silky skin in my palm. I squeezed it gently, loving the feeling of how the soft flesh gave away to my grip. Meanwhile, Lola was slowly rubbing the growing tent in my trunks, running her hand up and down the increasing length.
Suddenly, she slid closer to me and pulled her large bang along. She placed it on top of our knees, hiding the view of our crotches from our parents. In a quick motion, both of her hands worked to unbutton my trunks and whip out my erect cock. She let out a soft moan, no louder than a whisper as she gazed at my hard-on.
"Damn, looks like you really needed me, Log," She whispered, looking back ahead to the front as she wrapped a hand around my large rod.
I earned my nickname from my sister due to the size of my cock. Even at my age and height, the length of my member sat around 6 inches. However, that was when it was flaccid.
My sister let out soft gasps as she began to stroke my cock, running her hand up and down its impressive length. It grew harder and harder, until it stood fully erect at almost 9 1/2 inches in length.
I let out a soft groan and leaned my head back. I squeezed my sister's thigh a little harder, and she let out a squeak.
"Everything alright back there?" My dad called, not taking his eyes off the road.
"Yep, everything's fine!" Lola replied, gently squeezing my cock and getting me to stop squeezing her thigh. She looked over at me, arching an eyebrow. However, despite the annoyed look she tried really hard to put on, I could see a hungry type of lust in her gorgeous eyes.
It was the same type of look she gave me not too long ago, when this all first started.
I threw my bag down onto the family room couch and headed over to the dining table that sat between the kitchen and backyard door.
I paused by the backdoor, which was a large sliding glass screen that led to a small deck overlooking a miniature pool. My eyes widened slightly as I saw my sister laying on one of the lawn chairs, suntanning. She wore a sexy blue bikini, with thin straps and tiny triangles that barely covered my nipples and pussy.
She absolutely loved the beach and beach volleyball, which brought on her desire to sunbathe in our backyard. This is where I get into trouble because she often sunbathes completely naked or in extremely skimpy bikinis to get an even tan and her favorite place to do it is in our backyard. Our parents don't seem to care, and I don't think the neighbors ever notice, or if they do, they don't care as well. She would always come straight from her room to the lounge chair outside, all the while being completely naked or in her sexy beach fits. Whenever I would see her come from her room to walk down the stairs to sunbathe it killed me a little inside each time, but it was always the best part of my day to see those sexy tits bounce their way down and take that turn to go outside.
She knew I could see her, even if it was always a brief trip but my erection each time would cause me to do the same thing every time and that was to go to her room and look out her window to see her tan in the backyard. What hot --blooded male would resist such easy access to an attractive teen girl? I was compelled to look down at her and stroke my cock every time I knew she was out there. I've masturbated while viewing this amazingness before me many many times and each time it somehow got better. I never ejaculated more cum than I do when I jack off to Lola.
I think she got a kick out of it, knowing how hot she is and being naked while her brother is in the house, possibly with a huge boner. Whenever our parents weren't home, she would take the opportunity to masturbate while outside. Her right hand would be buried in between her legs, and she would be shaking and her body thriving back and forth in pleasure. Those few times were the best jack off experiences I've ever had.
Today, our parents weren't home, and she was laying outside in extremely sexy clothing. I couldn't help but quickly pull out a chair from the dining table and sit down by the curtains of the backyard door and whip out my already hard cock. I began to stroke it softly while leaning forward and gazing at my sister's delicious figure.
"Logan!" My sister called out suddenly. I froze, my grip on my own cock tightening as precum oozed out from it.
I had always masturbated to my sister whenever our parents weren't home, and I have done it a couple of times by the screen door. I didn't think it was possible she could see me from where she was, or even know I was jerking off to her. However, I wouldn't put it past her thinking that I was playing with myself at the sight of her nude body.
"Come out here!" She yelled again, not moving from her position on the chair. I quickly stood up and jammed my still hard cock into my pants. Straightening out my clothes, I walked out into the backyard and made my way over to my sister. I stopped next to her and fidgeted slightly as my cock still pushed against my pants.
