Sibling Sex Ch. 01

"Are you sure you don't want to come with us?" My mother seemed disappointed when I told her I had no interest in looking at old furniture, but surprisingly, didn't insist. "Well," she replied. "It's your loss."

"I don't think I'm going to go either." Though it was said without pretense, Shelly's declaration struck me like a thunderclap and my heart skipped. For a moment, I forgot to play it cool and openly stared at her in disbelief. Panicked questions flooded my mind. "Should I just go to the antiques shop? No, it'd seem strange if I changed my mind. They'd know something was up, right?"

"I don't know," my father said. "I think you should probably come with us. Besides, two kids here alone, there's nobody to look after you."

"Dad," Shelly remarked. "I'm 18 now, I don't need someone to stay here with me. Besides, I'm just going to read my book."

"I'm not planning to go," my grandmother volunteered. "I was just there earlier this week and it's not like we need any more furniture. I can stay with the kids - not a problem."

My mom and dad exchanged a look, then acquiesced. "Alright." my mom said. "But don't leave the house without letting grandma know where you're going."

By agreeing that we could stay home, my parents inadvertently elevated my anxiety level to pure panic. I found myself hoping they'd change their minds and stay home. But, once the dishes were done and clothes were changed, my parents and grandfather piled into our SUV and drove off down the county road.

The house was quiet after they left, which made me feel jumpy. I'd brought along a couple of Sports Illustrated magazines, so I took up residence on the living room couch and started reading, doing my best to appear nonchalant. My forced literary activity endured for about 20 minutes -- right up to the moment I heard Shelly ask our grandmother a question.

"Hey, Mimi!" Her voice drifted melodically through the house. "Do you mind if we go for a walk?"

"Where?" my grandmother inquired.

"I dunno... Probably down to the lake or out to see the horses."

"As long as you stay off the road, it's fine with me." Our grandmother continued, offering words of caution. "And make sure to put on sunscreen before you go out! Today's gonna be a real scorcher."

Moments later, before I could think to run and hide, Shelly bounded into the living room with a beaming smile on her face and a tube of sunscreen in her hand.

"Come on!" she implored. "Get your shoes!"

As they had the night before, my id and ego launched into an epic battle. All the while, I sat there on the couch, staring at my sister with a stupid expression on my face. She cocked her head and fixed me with a look that was equal parts amusement and annoyance. Then, in a master stroke of manipulation, she raised her voice.

"Grandma!" she yelled. "Don't you think it'd be a good idea if Jeremy went with me?"

Sure enough, my grandmother appeared from around the corner. "Jeremy," she said with a smile. "Be a good brother and go with Shelly. Don't let her fall down any wells."

I knew it was pointless to protest, and that if I did, I might alert my grandmother to the fact that something was bothering me. Recognizing my defeat, I said simply, "okay," then stood up from the couch and went to retrieve my shoes. On my way out of the room, I glanced over at my sister. She smiled back at me with an expression of wicked delight that made my knees weak.

In my bedroom, I sat on the edge of the bed and breathed deep. It took all my brain power just to put on my tennis shoes. It was obvious Shelly was up to something and my gut was clenched in terror and anticipation. It also occurred to me that my grandmother was in a better mood than usual. Her typical approach was to meet every day with a frown, so why did she seem so... happy? I shook my head and set myself to the task before me. Shoes finally on, I stepped through the front door.

My grandmother wasn't kidding when she said the sun might cook us. Even though it wasn't yet noon, the temperature was already approaching 90 degrees. I squinted as my eyes adjusted to the blinding light and looked around. Just then, my sister walked up the sidewalk and stood before me.

She was still wearing her high-cut gym shorts, but she'd cinched up the bottom of her t-shirt and added flip-flops to the ensemble. I couldn't help but look at her bare stomach, her abdominal muscles perfectly tensed and visible, and then on down to her legs and feet. The ball of tension that was gripping my stomach expanded to my crotch and I forced myself to breathe.

"Here." She held out the tube of sunscreen. "Help me with this."

"Why can't you do it?" As her older brother, I couldn't help but be annoyed when she bossed me around and took it as my responsibility to set her straight.

Shelly's face morphed into a mocking pout, her bottom lip jutting out almost comically. "Should I go tell Grandma you won't help me?"

Her playful pouting proved to be surprisingly attractive and cut through my defenses. I muttered "fine" and took the bottle of sunscreen. With a coy wink, she turned and lifted her long brown hair away from her neck. I distinctly remember my hands shaking as I popped the lid and squirted a dollop into my open hand. I took a step forward and steeled myself, finally putting my hand on her warm skin. That contact made me feel better, like I'd faced my fear, and I began working the white liquid over her exposed neck.

"Don't forget my ears." Once I'd satisfied that request, she let me know my work wasn't done. "Oh, get my back too!" I looked down and saw she was pulling her already-cinched shirt even higher. I stared in awe at the smooth, powerful curves of her back and the two small dimples just above her shorts.

I squeezed a healthy amount of sunscreen into my left palm, then dropped the bottle and rubbed both hands together. I turned them over, so my fingers pointed to the ground, and slowly rubbed the lotion on her back. Her muscles were taut, and unwittingly, I applied more pressure. She arched her back and purred as I ran my slick hands over her back

"That feels good!" Her voice was like honey and pride surged through my chest; despite my better judgment, I was elated that she liked the way my hands felt on her body.

"The sides," she said. "Get my sides."

Without hesitation, I slid my hands forward onto her supple hips, and somewhere deep in my locked mind, a tumbler clicked free. I couldn't believe it; I had my hands on a girl's hips! Sure, she was my sister, but the primal mixture of passion and power I felt in that moment was intoxicating. I wanted the moment to last forever, but I had a job to do. Slowly, and with great care, I began sliding my sunscreen-coated hands up and down her sides. I felt the slight curves of her body and excitement caused me to tighten my grip.

Shelly giggled; her tittering laugh made me feel self-conscious. I realized that my grandmother, were she to look out the window, would be greeted with a curious sight. She'd demand to know why I was standing directly behind my sister, my enlarged crotch only inches from her backside, running my hands slowly up and down her hips. I'd protest of course, making sure everyone knew how much I hated the task at hand. But I knew my blissed-out expression would betray how much I was enjoying the moment.

As nonchalantly as I could, I pulled my hands from Shelly's hips and stepped back, then bent down to pick up the sunscreen. While my head was lowered, I snuck a peek at her tight, nubile ass. The risk was definitely worth the reward!

Moments later, we headed off down the gravel driveway and away from our grandparents' house. We moved through a cattle gate and down the well-beaten path toward the horse pasture. My mind was lost in thought as I followed my fast-moving sister. As such, it took me a minute to realize she was leading us in the wrong direction.

"Hey! Grandma told us to stay away from the road."

"No," Shelly corrected me. "Grandma said not to go on the road, which we aren't"

"Yeah, but there's nothing that way but the fence line."

"Oh, just wait!". He tone was playfully dangerous and my curiosity got the better of me. A few quick minutes later, we came to the split-rail fence that marked the boundary of our grandparents' property line. Beyond it was the two-lane county highway we'd been warned away from, and for good reason. Cars would regularly come whizzing around the bend, and more than once, drivers had missed the turn and plowed through the fence line and into the field where we were standing.

Undeterred, Shelly ducked between the fence's wood rails. I watched her long legs stretch as she squatted down, her ass cheeks flexing against her shorts. Once through, she turned to look at me.

"Well?" she asked impatiently.

Ever the rule follower, I expressed my reservations. "Seriously, if we get caught, I'm telling them it was your idea."

Shelly smiled and motioned at me with her hand. "We're not going to get caught. Trust me."

I felt I had no choice but to follow her lead. Besides, what sort of brother would I be if I left my sister alone on the side of the road? Moments later, we were traipsing through the deep ravine that ran alongside the highway. The ravine was effectively at the bottom of a hill, and if we wanted to cross the road, we would have had to climb 20 feet up the steep bank.

We didn't have to travel far, maybe 50 yards, before we reached our destination. To my surprise, we were standing before a massive circular underpass cut. It was cut directly into the earth under the road and lined with concrete. It was at least ten feet tall, and as I looked it over, I realized it was a water spillway.

"How'd you even know this was here?" I asked.

Shelly beamed with pride. "Last Thanksgiving when we were here, I was walking the field with Grandpa after they cut hay and saw it." With that, she turned and headed into the tunnel. "Come on!"

Timidly, I followed. We didn't have to go far before our surroundings started to feel foreign and more than a little spooky. Though the large opening we'd entered through was only a dozen or so feet away, the tunnel began to feel like a cave. A car passed over the top of us and the distorted rumbling stopped me in my tracks.

"Isn't this cool?" my sister asked.

"Yeah. Kinda."

We progressed to the center of the underpass and I began to feel hyper-aware of my surroundings. The air was thick and my heartbeat pounded in my throat. Shelly deliberately looked around the concrete passage as though she was admiring a new home, then turned and flashed me a mischievous smile.

"So," she asked. "What'ya want to do?"

"Uh, I dunno. I guess we could see what's on the other side?"

She shook her head. "That's no fun."

"Okay." I could hear the uncertainty in my voice. "Then what?"

She stared at me with a playful expression but said nothing. After a long, unnerving moment, I shrugged, doing my best to seem aloof.

"What?" I asked.

She cocked her head and I watched as her eyes fell to my crotch. Her boldness sent a shiver up my spine and I felt my penis twitch.

"Last night in the car, when I touched your... penis." She continued staring straight at my crotch. "You orgasmed on my hand, didn't you?"

"What?" My protesting yell reverberated off the circular concrete walls. I immediately lowered my voice, terrified that someone might hear us. "No, I didn't."

"Yes, you did!" She looked up and met my gaze. "What else could it have been? Spit?"

I didn't know whether to get angry or run away. So naturally, I did neither and just stood there, dumbfounded. Again, she dropped her eyes to my crotch and made it obvious she could see my excitement.

"Does it get hard like that a lot?" she asked.

I blushed, realizing that my growing penis had rendered my protests pointless, and answered half-heartedly. "Sometimes, yeah"

Another moment of silence passed between us, then she cut to the chase.

"Can I see it again?" she said.

"What?" I desperately wanted to grant her request, but my programmed morality made one last attempt at standing its ground. "No way!"

"Why not?" Shelly looked genuinely sad. "I mean, I already touched it, didn't I?"

I couldn't think of a convincing rebuttal, so like an idiot, I just stared at her in silence. She regarded me for a moment, then produced a counteroffer. "What if I show you mine?"

For the second time that day, I felt like I might faint. I felt confused, unsure of what to do, but an animalistic urge rose up and took control. "Show me your what?" I asked, barely able to believe the opportunity unfolding before me.

Confidently, she shot back. "Whatever you want."

I needed only a moment to consider her offer. Part of me wondered if she was just toying with me, trying to work me up so she could run away like a bratty tease. But there was only one way to find out.

"I wanna see your tits. I mean, your breasts." My words were breathless and rushed. Without hesitation, Shelly undid the knot on the side of her t-shirt, then pulled it up and over her head. And for the first time in my life, I found myself looking at a girl's breasts.

Don't get it twisted, I'd seen a Playboy magazine or two. But those reproduced images paled in comparison to the vision before me.

As I stared at her chest, I realized a couple of things: 1. Breasts were one of God's greatest creations and 2., my sister's breasts were larger than I realized. Their deceptive size was likely due to how firm they were. Their shape was perfect and pronounced, and if she'd told me they were fake, I might have believed her.

My sister's tits had a graceful slope. They were largest at their base and perfectly round, almost as if they'd been lovingly sculpted from clay. But what really blew me away were her nipples. They were puffy and dark pink and they looked like tasty gumdrops, especially now - all covered with glistening sweat. After what seemed like an eternity, I looked up to find her beaming at me with pride.

"You like them?" She delighted in my enthusiastic nod, her electric smile growing even brighter. "You wanna touch them?" My head and my cock nodded in unison. I stepped to her and she thrust her chest out at me. I reached one hand up and tentatively felt the sides of her left breast. To this day, the sheer ecstasy of that first touch is one of my happiest memories. I lifted my other hand, placed them both over her tits, my palms on her puffy nipples, and gently squeezed.

"You should pinch my nipples," Shelly said. I must have groaned because her expression became one of concern. "You okay?" she asked. I tried to convey confidence with a nod and smile but must have failed miserably. She misinterpreted my hesitation and focused expression as displeasure and pulled away.

"No." Her voice cracked and I could tell her feelings were hurt. "You don't like them. I can tell. They're too small, aren't they?"

Horrified by my unintentional offense, I finally remembered how to talk.

"What? No! No way! They're amazing! Really, they're the most amazing, beautiful things I've ever seen. I just... I'm just really nervous and..." I looked down at the front of my shorts; the outline of my hard cock, running down my thigh, was pronounced. "Honestly, I'm so horny it hurts."

Her expression returned to its prior, lustful state. "Well then, you should take it out, don't you think?"

"Are you sure?" I asked.

My sister threw me a pleading pout. "Please? I really wanna see it."

My resistance crumbled. I felt a twinge of regret as I pulled my hands from her perky, hard-nippled tits, but reminded myself of the greater glory. With trembling fingers, I undid the top button, grasped the fly and unzipped my shorts. They fell quickly to the ground and I slowly lowered my boxer shorts. My penis sprang free and my sister's mouth fell open in awe as my cock bobbed before her.

"Oh my god!" she exclaimed. "It's so big! I've never seen one that big!"

"What?" I felt somehow betrayed. "How many have you seen?"

She smiled wickedly. "A few."

I realized I didn't care how many other penises she'd seen. As long as she wanted to look at mine, I was the luckiest guy in the world. I stood tall and even pulled my shirt up a little to allow her an unimpeded view of my throbbing, swaying cock. I felt emboldened by her attention and flattered by the look of shock and admiration on her face.

Standing there, hard as a rock, was wonderfully difficult. I was so excited, I knew the slightest breeze might cause me to explode. Though I didn't want to cut the moment short, I felt better than I had in my entire life. So what if I came? I didn't think either of us would be too upset if I had a spontaneous orgasm.

We both stood there, me displaying myself and her taking in the sight. I figured I should take the initiative and make a move; I just didn't know what move to make. Thankfully, my sister did it for me. Shelly looked up from my cock, ran her tongue over her smiling lips, then reached up and started pulling at her puffy, pink nipples with both hands. I watched, mesmerized, as the greatest sight I'd ever seen played out before me.

"Does that feel good?" I cursed myself for asking such a vapid question, but my sister didn't seem to mind. She nodded, her eyes never leaving mine.

"Yeah." Her words were breathless and I could hear her bliss. "It's even better when they're wet."

Ever the opportunist, I bent over, careful to avoid touching my hair-trigger penis, and fished the bottle of sunscreen from my shorts.

"Would this help?"

Without speaking, she stepped to me and snatched the plastic tube from my hands. I stared in awe as her naked body came within inches of my own and I contemplated wrapping my arms around her and pulling her against me. Inflamed and focused, she quickly popped open the lid, held the bottle above her chest, and squirted the white liquid onto both her breasts. The ropy strands of sunscreen landed high on her chest and began sliding down.

Shelly dropped the bottle and began smearing sunscreen all over her tits. Once the prominent points of her breasts were adequately covered, she began squeezing the puffy pink nubs between her thumbs and forefingers. The lotion worked as intended; my sister bit her lip, closed her eyes, and began to whimper. Enthralled, I watched as she tugged and twisted her nipples with abandon, all the while moaning as though she were in a porno.

My cock called to me, begging for release, but I couldn't stand the thought of making an early exit. Besides, if I jacked off, who knew what other activities I might miss out on? As I struggled to keep my hands away from my desperate penis, my sister, her eyes still closed, began talking to me.

"Oh my god! Jeremy!!" She was practically hissing at me. "Do you want to touch them some more? They feel so fucking good. Do you wanna touch them?"

Even though my mind was screaming "yes!" I was back to acting like a mute. When she didn't get a response, she opened her eyes and threw me a look of lustful urgency. I'm sure I looked foolish, standing there nodding like a goofball while my cock bobbed in time with my heartbeat, but my sister, ever the opportunist, saw only what she wanted and stepped to me. She dropped her hands, thrust her chest out at me as she smiled, and said only, "do it!"

Shaking with excitement, I reached my hands up and grabbed her pert breasts for the second time that afternoon. Despite the fact I was having an out-of-body experience, my hands showed no hesitation. The difference from earlier was noticeable. Where her tits had seemed hard and resistant the first time I touched them, now, covered with slick sunscreen, they felt soft and supple. I began massaging her firm handfuls and she responded by pressing herself forward and moaning. "Oh my God!" Her voice was sultry. "That feels so good."
