It was a magnificent Sunday; the sun was casting its golden rays upon a grateful world. Not a breath of air could be felt while birds sang and frolicked amidst the trees. Enjoying the day was my family and I, sitting in an otherwise deserted picnic area finishing our barbeque lunch.

On one side of the table strewn with the remnants of a delicious meal sat my parents. On the other was my eighteen-year-old sister Katie and I, her golden curls catching the light and drawing attention to her dazzling blue eyes. I couldn't help but sneak glances down her wondrous form clad in a thin summer dress, the smooth skin of her shoulders giving way to her deep cleavage just begging for my touch. While under the table her seemingly endless legs were pressed against mine, a constant reminder of our past adventures together.

Dad was telling stories again, the ones we'd all heard a million times but still had to appear attentive too. It was all I could do to keep my eyes open as he droned on and on. It was in the middle of one of his oldest and most boring tales that I felt a hand rubbing my thigh, the gentle touch sending an instant lightning bolt through my system.

Casting a sideways glance at my little sister I could see the corner of her mouth curling as the hand in question traced it's way closer to its prize. Every millimeter of skin traveled on it's journey heightening my anticipation a hundred fold.

She picked her moment to perfection; just as I was dutifully laughing at one of dad's jokes her petite fingers found my member, circling it through my shorts. It took all my self-control not to moan out loud as Katie started to massage my package under the table while chatting to our parents. It was not long till she was stroking my hard shaft with long rhythmic motions, heightening my arousal to it's maximum potential.

Not to be undone by my naughty little sister, I also stealthily moved my hand under the tabletop. I waited till Katie was telling mum about her latest school assignment before gently stroking her smooth thigh. I don't think anyone else noticed sis jump as my fingertips trailed ever so softly along her skin.

Circling lazily, I teased her for minutes on end, her hand becoming more insistent on my cock by the minute. Her legs opened wider without conscious thought as my questing hand continuing it's slow inexorable journey to her panty-clad treasure.

It must have seemed to Mum that she was having trouble explaining her schoolwork, yet I knew better. As my fingers reached their goal a small sigh escaped her lips, luckily neither of the oldies noticed. The hand on my cock was stroking rapidly as I rubbed her smooth mound through the sheer panties encasing it.

Done with my initial exploration of my little sister's crotch, I moved on to the next level. Slowly pulling the soaked cloth aside, I ran my fingers over my sister's soft, wet folds while discussing the pros and cons of all the sports teams this year with dad.

Mum was starting to pack the leftover food into the cooler, completely oblivious to my actions under the table as I circled her little girl's clit. Out of the corner of my eye I saw Katie leaning back on the bench, this was my queue to spread her nether lips and slowly sink two fingers into her waiting hole.

The heat emanating from her tight eighteen-year-old snatch felt like it would burn my fingers as the wet walls clenched my digits. Her hand was merely gripping my shaft now as my fingertips searched out every corner of her tunnel, making sure I didn't miss a single square millimeter.

When I found her g-spot Katie jumped slightly, her toned thighs rapidly clenching and releasing my hand. Massaging her most sensitive spot with increasingly rapid movements I couldn't help but smile. I love nothing more than pleasuring my little sister, and doing so in such a risky situation just added to my enjoyment.

I distracted our parents with a tale about something or other as my little sister's heaving chest with its rock hard nipples readily apparent through the dress drew my discreet glances.

Turning to each other our parents were planning an after lunch bush walk. Seeing their lack of attention I lent close to Katie's ear and whispered "cum for my sis" while thrusting my fingers repeatedly into her squishy pussy and rubbing her engorged clit with my thumb.

She needed no urging as her body was rocked by a powerful orgasm, her teeth clenching to prevent a moan escaping her lips. Her eyes were screwed shut as her head was thrown back by the pleasure coursing through her body. The sun caught her hair and turned it into a golden halo that took my breath away.

As sis came back to reality her now shaky thighs released my hand from their vice-like grip. I couldn't pass up the opportunity to bring my fingers to my mouth and taste her delicious juice.

My sister's eyes were locked on my every move as I licked every trace of her nectar from my digits. The taste and smell of her heavenly wetness made me moan softly, my cock a steel bar in Katie's hand, staining against my shorts.

Mum and Dad picked that moment to turn back to us and lay out their plan for a long bush walk to help digest lunch. Mum immediately commented on Katie's flushed state, her concern for her baby girl clearly evident. Sis covered nicely with an excuse about the sun being so hot on her fair skin.

Mum had no way of knowing about the love juice soaking into the picnic bench under her little darling, or that her hand was running over her big brother's engorged cock the whole time she was speaking.

I stepped in at this point to explain how I thought Katie was in no condition to go walking in the hot sun. Wouldn't it be better if she stayed here and rested in the shade? I even managed to make myself sound less than pleased to be volunteering to stay behind and look after her.

To my immense relief they bought my story, agreeing to my plan and standing to leave with a final comment on what a nice big brother I was.

Our parents had barely disappeared into the tree line when Katie and I engulfed each other in a crushing hug and passionate kiss. Her hand was desperately trying to release my hard cock from its confines as I squeezed her magnificent big boobs and our tongues dueled in our locked mouths.

Our sibling love was palpable as we tore at each other's clothing while maintaining our extremely erotic kiss. Freeing her mounds from the dress encasing them I exposed their glory to the warm sunlight, the little bullets of her nipples standing proud.

With a final kiss to her soft lips and a lustful look of silent communication I moved down to worship them with my mouth and tongue. My young sister moaned loudly as I covered her breasts with kisses before alternating between each hard nipple, sucking them hard.

I was enjoying myself immensely as I sucked as much of her tit flesh into my mouth as possible. My hand gripped and squeezed her hard nubs as I made my way down into the deep valley of her cleavage, her breasts pressing against both my cheeks as I traced my tongue up the valley between them. Emerging back into the light I kissed my way up Katie's slender neck to her mouth, finding her lips parted and ready for my loving kiss.

Pushing me away from her Katie bid me stand and rest my buttocks against the picnic table in front of her. This left my straining member directly in front of her beautiful face, a thin layer of material the only thing between her and it's quivering shaft.

Gripping my waistband in both hands she drew down my pants, my cock jumping out dramatically, grateful for the freedom of the great outdoors. Looking me in the eye, her blue orbs captivated me as my little sister stretched out her tongue to tease the tip of my rod.

I could only groan in appreciation as she slowly traced her tongue along my shaft, making sure she didn't miss a single spot. Eventually making her way to my balls she took first one, then the other into her heavenly mouth, sucking them gently.

My breath was coming raggedly as her tongue traced its way back up my cock before her mouth plunged down onto me. With the warmth of her mouth encasing my cock, it was all I could do not to cum. My hands rested in her hair as she slowly drew more of me into her mouth, her hand playing with my balls as the other stroked her own wetness.

Moving back to take a breath Katie winked at me before taking my saliva coated shaft deep in her throat, before my astonished eyes she didn't stop until my heavy balls rested against her chin. The feeling of her throat muscles massaging my shaft was indescribable.

With the warm sun on our skin I wrapped my hand in my little sisters' hair and started to gently thrust myself within her mouth, her moans all the encouragement I needed. Finding a glorious rhythm my naughty sister allowed me to fuck her mouth and throat to my hearts content, the picnic area becoming filled with the sound of lewd slurping and sucking.

After several thrusts she would pull back for a breath, sometimes followed by a quick lap of my heavy testicles, before plunging back down onto me. It did not take much of this amazing attention for me to feel the signs of my impending orgasm; it started down in my toes and rapidly traveled up to my crotch.

With a final thrust that buried my cock in her throat I erupted. I saw stars as my seed pumped into Katie's throat and mouth, a small rivulet appearing at the corner of her lips as she was unable to swallow it all. My penis continued to twitch as she cleaned me of any trace of cum, moaning at the taste as she swallowed deeply.

Raising her up I kissed my beautiful girl deeply, tasting myself on her tongue as my hands explored her body. Stripping each other completely in a flurry of passion, we pressed our warm bodies together as we bathed in the sun's glow.

I desperately wanted to taste my sister, laying her gorgeous form on the picnic table where our parents had sat so recently I positioned her so that her delicious wet pussy was at the edge in front of my waiting mouth. With her boobs standing proud in the sun I spread Katie's legs and admired her beautiful hairless nether regions, her pink lips opening in anticipation of my tongue. A delicious looking sheen of juice coating her thighs and pussy, the hard nub of her clit peeking from beneath it's hood.

Teasing her slightly I cleaned the wetness from her thighs, my tongue tracing lazy circles on her sensitive flesh. Hearing her demands to stop teasing, I dove in to slurp her juices with gusto, my tongue exploring her folds and circling her hard clit. Her hand came to rest on my head as I spread her lips to grant me access to her slit, my tongue plunging into her body like a miniature penis. With my mind filled with her moans and the delicious aroma of her pussy I could feel my cock coming back to life in record time.

Forcefully moving my mouth to her clit Katie begged me to make her cum. The gentleman in me couldn't say no to a request like that. Taking the hard bundle of nerves in my mouth I sucked it hard, my tongue swirling over it incessantly. Burying several fingers in her quivering love tunnel I sort out her g-spot and massaged it in time with my tongues movements.

I kept this up for only a very short time before she hit climax. With a scream that startled the birds Katie came, her back arching of the table and her thighs locking me tight against her crotch. I could feel her pussy clenching around my fingers as I struggled to lap up all her love juice, my face swiftly becoming covered.

As her body started to relax I quickly stood and positioned my re-energized head against the mouth of her pussy. With one smooth thrust I buried myself in her wetness, our moans of pleasure merging into one. As my balls came to rest against my little sisters butt she came again. A small orgasm making her face contort in an image of pure lust as she moaned my name. I gave her no time to recover, thrusting my hard cock into her pliant body in long strokes.

Pulling back till just the head was inside I would plunge forward to the hilt, repeating the process over and over. I felt amazing to slide into her pussy as she wriggled on the tabletop, her boobs catching the sunlight. Leaning forward I maintained my rhythm as I sucked her nipple into my mouth once again.

Quickly tiring, I joined Katie on the tabletop, pulling her on top of me for a passionate kiss. With her tongue madly licking her own juice from my face, sis straddled me and sank down onto my cock, her hips rotating to enhance our pleasure immeasurably. My hands came to rest on her firm butt cheeks as she gyrated on my shaft. Grinding herself against me her nipples were spearing into my chest as we once again explored each other's mouths with our tongues.

Raising herself up I was able to massage her tits as sis started to bounce on my cock, the head penetrating deep into her body with every stroke. I lay back and admired my sister's beauty in the sunlight, her head lolled backward with her eyes closed, completely overcome by lust. Her body seemed to be moving without conscious control as she drew herself up before slamming back down onto me, my rod stretching her pussy lips open like the petals of a beautiful flower. Slipping my hand lower I was able to massage her clit as she slid her body up and down my cock. A soft chanting of "oh my god" and "fuck me" filled the picnic area as she satisfied her primal urges.

Leaning close to me, my little sister locked my gaze with her bottomless blue eyes and ordered me sternly: "fuck me doggie big brother." Without further words she slipped of my cock, the air cold against my wet member. Carefully stepping down from the table top Kate positioned herself at the end of the table and bent forward at the waist, pressing her boobs against the tabletop.

Seeing her in this incredible erotic position I was off the table and behind her in a flash. Gripping her hips firmly I sank home into her pussy with a sigh of pleasure echoed by both of us. As my balls slapped home against her clit I pulled myself tight against her tight buttocks, enjoying the feeling of being buried in my eighteen-year-old sister's body. Her inner muscles were clenching my shaft as I withdrew half way and plunged back in fully, the air being expelled from her lungs with the force of my thrust.

Starting to pump furiously I slammed myself into Katie's pliant body, her groans of pleasure egging me on. With each thrust I would withdraw till only the head remained inside her body, then with a single movement I would be buried once again to the hilt, my balls slapping her clit loudly. I kept this up for several minutes, sis matching my movements with her own.

Her hips were moving in erotic circles as her butt cheeks rippled with the impact of my assault, the wet slapping sound of our joining loud in our ears. With a final hard thrust she came, her mouth opening in a silent, breathless scream as her body convulsed with the power of her orgasm. My cock left her body with a wet slurping sound as she collapsed forward onto the table.

Katie's body was shaking with aftershocks as I wrapped her in a loving embrace from behind. My hardness nestled between her beautiful cheeks as I held her tight and kissed her hair softly. She finally returned to earth after several minutes, slowly turning to face me and planting the most sensual kiss I have ever experienced upon my lips. As it ended I was left gasping for breath, my cock a steel bar against my sister's belly. Feeling it pressing into her sis slowly lowered herself to her knees on the soft grass, her nipples dragging twin trails of fire down my body.

Watching my face intently, Katie blew me a kiss before wrapping her lips around my hard member, slurping it wetly. With sisterly tenderness she made sure I was completely coated in saliva before pulling herself off my shaft. My squawk of protest was cut incredibly short as she proceeded to wrap her magnificent breasts around my cock.

Looking up at me she told me in her best little girl voice to "fuck my tits till you cum big brother." I needed no urging, sliding my rod between her mounds I was in nirvana, the soft flesh encasing me while her tongue snaked out to lick the tip of my head on every thrust. Seeing my cock between my little sister's glorious boobs sent me over the edge, my head lolled back as my moan filled the picnic area.

My cock pulsated madly as my hot cum splashed over Katie's boobs and throat, one particularly forceful spurt striking her square on the nose. I almost blacked out as she took my super sensitive cock in her mouth and sucked my clean, swallowing the remnants of my seed with gusto. To my amazement she then proceeded to scoop up all the cum she could find plastered on her body and gobble it up like it was her favorite treat. When she finished I lifted her up gently and wrapped her in my arms, placing a loving kiss on my little sisters lips.

Our unsuspecting parents returned half an hour later to find Katie and I snoozing on the grass in the shade under a tree. We were both dress exactly as we had been when they left and they were very pleased to find their little angel was feeling better. I received their thanks for staying back with her with great modesty, a private smile passing between my sister and I as we contemplated exactly how I had taken care of her.
