“C’mon let’s get that cage off that dick, let your big sister see it.” Abby said reaching into one of her underwear pockets for the key to the pink chastity cage she had placed on me earlier today.

As the key turned in the lock and the clasp released I felt Abby slowly and ever so gently remove my sexual binding. A thick cocktail of precum, sweat and semen covered every inch of my cock.

We she pulled away the stringy slimy cum almost appeared to make a spiders web between my cock and the cage. Once I was fully free Abby chucked the cage to the floor, discarding it with glee.

Finally my time had come. “Let’s go already!” She ordered grabbing my growing member and practically dragging me out the door. Being tugged along was enthrallingly erotic, I grew firm and before I was ushered out into the living room I had already peaked in size and girth.

Abby hummed softly as she pulled, opening the front door to the house. Immediately I felt the hot sun on my pasty skin and a cold wave of fear. I was outside of my family home, houses to all sides and here I stood being dragged, cock first, by a goddess who I was privileged enough to call my sister.

She released her grip and pushed me into the driveway, my lower half naked and in view for all to see. She giggled, raising her hand to her mouth before throwing me a pair of pants she was holding in her other hand. She still held onto a short white tennis skirt and a hot pink crop top.

With haste I pulled the pants over my legs, tucking my still thick and throbbing cock into the pants. My member pushed hard against the material leaving a perfect carve out of my penis.

Abby threw the crop top on hastily, one strap not even over her shoulder as she pulled her super short tennis skirt up over her fat juicy ass. I couldn’t help staring at her, her gorgeous frame a visual feast that made me a mushed brain Neanderthal. She could say or ask anything of me and I’d comply.

I noticed in that moment she was looking at my cock’s outline and was ever so slightly biting her lip. As we stood across the driveway, like two gunslingers from an old western I felt the needling thought of jealousy dig at my conscious. Before I could catch the words I spoke;

“Do you like Chase?”

A veil of awkward silence fell over us as I studied her face. She screwed her immaculate features up before walking over to me. “Sure he has a big dick and it hits all the right spots, but no Jakey I don’t have feelings for him.” She pushed herself into my personal space her head next to my ear. Her hot breath blowing gently onto my neck.

Through sultry and sensual notes she finished; “not like the feelings I have for you Daddy.” As if to punctuate her sentence she let out a moan into my ear canal, sending a jolt of adrenaline down my spine. She backed away and slammed a rogue pair of keys into my hand.

I looked down at them in confusion.

“The stick shift keys? Where’s my car?”

Abby smiled pulling the loose crop top strap onto her shoulder; “mum and dad were doing errands and dad said he wanted to take it for a spin, he doesn’t think you take care of it. But I know you take care of what belongs to you.” She said, winking at me.

With flush red cheeks I turned around toward the car, not knowing what to say or do. Unlocking the quickly I saw Abby run around to the passenger side and jump in. I turned the car on, and slowly reversed out of the driveway. The car clunked as I failed to smoothly switch gears.

“Fuck I hate driving stick.” I said aloud almost forgetting Abby was here.

“Oh cheer up Jakey.” She began as we rounded the street, “you focus on the car’s stick and I’ll focus on yours okay?” She said, her sexy accent dancing across every syllable. She was rubbing my member through my pants. Her soft hands rubbed and fondled me ever so lovingly as we drove on.

Her painted red nails caught my eyes as the sun glistened off them. As we reached the busier streets we came to a stop light, the first of many. As we pulled to a stop and the car idly shook, Abby, in her wickedly sexual voice began to speak;

“I said today will be a day of experiences, naughty experiences. So we’re going to play a little game —“ she began, pulling my cock and balls free from the baggy pants. She leaned down and wrapped her hot, wet lips around my aching shaft and sucked me with ferocity.

I felt myself twinging and pulsing and it felt like time went still. If I didn’t focus immensely I would’ve cum right then and there. “— I’m going to suck you off, the faster you drive the faster and better I suck. The slower you go the worse It gets —“ she said nibbling my cock. Painful ecstasy caused my cock to grow even harder as she finished the sentence “— and if you stall or come to a dead-stop at any point during this ride, I’ll bite this mother fucker off!” She said now yelling, giving me a hard, firm warning bite to confirm any lingering doubts I had.

As if timed the light went green and I floored it, now effortlessly switching gears. I caught up to the speed limit and Abby sucked me with an unrivalled tenacity. Warm saliva poured down my throbbing shaft as her hot lips worked my head and her tongue traced every inch of me. Wanting to bust in her beautiful slutty mouth I sped up, now going over the speed limit.

As I pushed my foot harder to the floor of the vehicle she tightened her juicy lips around my cock; slurp, glurp glurp she went as I tore down the busy streets. Green light after green light, we kept going, I pumped the Gas, dodging and serving between slow drivers on the lane way, two more sets of lights and a left and we’d be at the plaza centre. Abby tightened and pushed my fat cock down her tight warm throat until I felt her lips kissing the base of my dick. I sped up even more now as cars began to honk angrily at me.

It was pure bliss as I ran through a yellow light. I was on the verse of cumming a powerful load down her slender throat. She slid her mouth up now and worked the head of my cock, ferociously licking my frenulum. I throbbed and could feel the pressure building in my shaft and balls.

“Oh fuck I’m gonna cum I’m gonna cum.”

Up ahead was the final light which denied me my pleasure as, just then, as my eyes met it, it switched red. I was seconds away. I had to break, but I couldn’t or she’d stop if I did. I wanted nothing more than to empty my big balls into her throat and give her my seed. I wanted to pump my hot load into her holes, any hole. As my primal brain took over I punched the gas and flung it into the highest gear, running the red light.

As I zipped across the lane way, narrowly avoiding oncoming traffic, the blare of horns and intense sucking caused me to explode in violent pleasurable bliss. I shook in my chair and squirmed wildly. I could feel the hot warm semen being pumped by the mouthful down her slender throat as she slurped it down.

Even after I had finished she still continued to suck, my nerves overdosing on enjoyment, I nearly passed out. The sounds and feelings all merged in a cacophony of bliss. The pleasure was other worldly, it was almost too powerful. Powerful enough to drown out the sirens…

WEEWOO WEEWOO they screeched.

Abby lifted herself up off my cock and back into her chair as I whipped around the left corner, the plaza mere metres away. The sirens grew louder. I slowed down and pulled into the first car park I could find. Looking over at Abby now, my cock still out, she wiped a rogue rope of cum from her upper lip, sucking it off her slender finger. In a panic I screamed;

“I ran the light! What do I do?!”

With a gentle calmness, she searched the back seat grabbing a beach towel and my work apron.

“What good is that going to do us? I was going 110 in a 50!”

She turned to me, chucking the towel across my lap and gesturing for me to tuck it in. I did so without question. She threw her hair up into a loose ponytail and slid into the apron. Shockingly as the cop car pulled in behind us she grabbed a few eyelashes and yanked them out, her eyes welling with tears. She wound down the window and faced the now approaching officer;

“Want to tell me why you were driving so fast?” He said before Abby cut him off.

Through teary eyes and a blubbering speech she said “oh officer I’m so sorry. It’s my first day and my dad said he’d drive me but he left to play golf! My brother said he’d help but by the time he got back from the beach I was already late.” She said panting and out of breath

“it’s my first day and I need this job, college doesn’t pay itself, especially when you don’t have a scholarship.” She continued her words almost tripping over themselves. She pitched the word ‘scholarship’ and it sounded like a fine China plate smashing against the floor.

She began to uncontrollably weep. Seconds past before the cop intervened;

“Look kid, I know you had to get to work but you ran the light.”

“Ple-he-ease” she said through bursts of tears. “That ticket costs as much as my first semester’s books! Pls-he-ease.”

The cop, holding his pen and pad looked at me, curling his brow. I nodded in agreeable with her story. He lowered the pad slowly and leant against the door.

“I took down your plate boyo. If you even sneeze again while in this car I’ll take your license.” He said pointing at me. He backed away from the car and said, his tone final and abrupt “and tell your dad to get a fucking day planner!”

With that, he strolled back to his car, hoped in and drove away. I breathed a few panicky breaths, barely able to catch the air. I looked over at Abby who was no longer crying but smiling at me coyly;

“So how’d I do?” She said laying a much needed kiss on my lips.

Stunned I blinked at her, unable to form the sounds of words as she unclasped her seatbelt and opened the door. I followed suit and slammed my door. Running across the street to catch her, pocketing my cock as I did.

“Are you crazy?” I said grabbing her arm and pulling her toward me. She spun around her eyes dancing with tantalising hues of blue and green. “You haven’t seen anything yet.” She said in the same sexual tone as before our car ride.

Despite cumming only minutes prior her voice alone made my dick tremble and body squirm for her attention. I shook my head and gathered my thoughts. as I did I saw her standing at the entrance of the plaza tapping her foot.

“Let’s get your plan B and get home.” I said assertively.

She merely shook her head. “Today is about experiences and we’re just getting warmed up. I’m wearing your apron—“ she said taking it off and chucking it to me.

“Yeah so?”

“So! You’re going to go into the grocery store that you work at, across the way from the pharmacy and take me in with you.”

“You’ve been in there plenty of times.”

“Not with you. Not alone.”

I gulped as her stare stayed fixated on me. Casting aside my better judgement I chucked my apron on and headed around back, Abby in tow, toward the employee entrance. I tapped on the door the familiar clang hollow and ominous. The door opened from the inside as Jeremy, my coworker, greeted me. He had obliviously been on a lunch break as a stale cigarette hung out of his mouth, his black hair spilling from his hairnet.

“What do you want Jake, you ain’t working today?”

“True, but I know you are—“ I began looking over my shoulder to see my sister had mysteriously vanished. “—and I thought maybe you needed to take a leak?”

Jeremy raised an eyebrow as he puffed a smoke bloom into my face. “A leak?”

“Yeah since the boss only ever puts one person in the bakery section on Saturday I thought I could step in for a bit, my family is in the store grabbing some stuff for dinner.”

Jeremy furrowed his brow in a curious manner. He silently assessed me before walking deeper into the inner room, pushing past a “staff only” section and yelling as he went “I’ll be back in 10 Jake, don’t fuck me on this!”

“I won’t!” I called back.

“Good improv.” Abby said now standing beside me again.

“What? Where were you?”

“Hiding behind the door he opened, can’t let him see me.” She said pushing me inside and up against a prep table, complete with a floured counter top and dough balls.

Abby pushed past me and put some of the dough together making a larger ball. She then dropped her pants, flipped around and jumped onto the table ass first landing squarely on the dough. Her naked ass and pussy dripping sweet sweat and juice into the mixture. She raised her legs up onto the table, bending her legs at the knee allowing uninterrupted access to her glorious vagina.

With her eyes she gestured for me to go down on her. Immediately I complied finding myself buried almost instantly in her decadent pussy, the aroma itself enough to harden me to full mast. I hadn’t even licked three times before I felt the unfathomable wetness of her pussy soak my face. The car trip and cop near-miss had left her oozing. Her freshly shaved Pussy hungry for pleasure. With every lick she moved and adjusted, kneading the dough with her ass.

As I licked and she dropped more and more into the dough she playfully said through short moans; “oh that’s not sanitary. My juices have gone into the dough.” She said knowing full well her intent. Minutes later she pushed me off, the power knocking me into one of the shelves.

She stood up and ran over to me planting kiss after kiss on my neck and face, every so often biting me on the neck or nibbling on my cheeks. She reached into my pants with her free hands and began stroking with one hand while the other cupped my balls. Her touch was an instant turn on now, her voice even more so. A few hard and fast strokes from my cock hungry sister would cause me to bust all over my workplace, contaminating even more food.

Suddenly we heard a noise coming from the break room. Abby grabbed my pants quickly and hoisted them up. We dashed out the way we came in. Like a love sick puppy I followed Abby into the customer entrance to the store. Before I knew it we had a basket and were shopping. As Abby picked up various fruits and veggies she asked casually.

“So how is your Saturday so far?”

“I’ve never had one like it.” I said utterly truthfully

“And you never will again. You hungry?” She said raising a lettuce to my face.

“For certain things yes.” Trying my hand at being the flirty, sexual one

She playfully slapped my shoulder; “Jakey! We’re in public!” She said sarcastically as if we hadn’t dripped her juices into tomorrow’s baguette dough.

“I myself am starved I think we grab a few veggies for a salad, swing by the pharmacy and head home.” She said, in an almost motherly tone.

I simply nodded, grabbed the basket and followed her around as she loaded it up. She chucked in a lettuce, two tomatoes, some spanish onions and a thick cucumber.

Practically skipping I followed her to the checkouts where she made kind small talk with the lady teller Erin.

“You guy don’t normally shop on Saturdays.” Erin said astutely

“Yeah but Jake is sick, so mum made me get some stuff for a soup she’s going to make. Then we’re popping over to the pharmacy.”

“What’s he got?” Erin said addressing Abby as if I wasn’t even here.

Abby began to speak but kept her eyes locked on me; “oh you know, some cold. He’s got a lot of fluid, it is just so sticky and it just keeps cumming.” She said winking at me before turning around to pay Erin.

Disgusted at the sickness description, Erin swiped her card and simply nodded at me before calling for the next customer. As we abruptly left the store and made our way over to the pharmacy, Abby placed the basket in my hand and told me to wait outside “less suspicious that way.”

She said. Moments later she returned with a non descriptive bag and we headed for the car. As we entered and before I even had turned on the ignition her hand was down my pants, fondling my cock.

“Round two? Speed run? Let’s run some lightssss” she said, holding the ‘s’ as she ran her tongue over her soft lustful lips

I shook my head and started the car heading down the way we came, this time at regular speed. Abby smacked me hard in the nuts before pulling her hand away. I felt sick and could barely sit up straight as I drove the car around the corner.

With a huff of forceful air and a crossed set of arms she commented “oh you’re no fun.”

We arrived home much slower this time. The afternoon sun overhead, the days heat prominent and in full swing. I pulled the car into the driveway where I had found it and turned it off. Abby gave me a slight peck on the cheek before hoping out the car annoyed.

I grabbed the food bag and hurried in behind her, she threw the door closed in my face, narrowly I caught it and slipped inside, closing but not locking it. I rushed to catch up with her but she was making pace down the hall toward her room, my room and my parents room.

Finally I caught up to her and grabbed her arm, she spun around with a huff and glared at me. Like a frightened dog I fell to my knees and said I was sorry. Relinquishing any masculinity I had left I kissed her soft feet unprovoked, lifting her feet from her flats. I placed her toes in my mouth and sucked deeply as I looked up to breathe in her visage. I sucked and sucked until I felt I had gotten my point across. I removed her saliva covered foot from my said; “I’m sorry Abby let me make it up to you.”

With a piercing glare she knelt down to my level and said coldly; “with me Jake you’re either in or out. Today is your experience day; your last chance to back out. By tomorrow, today will have seemed like a fucking play date! So are you in or out?”

Scared, petrified, utterly exhilarated. I couldn’t fathom what I loved more; her soft caring nature, her sexy ravenous role play or her angry dominant persona. The way she spoke to me made me crumble. There was nobody like her. There was only one Abby. She wanted me, she chose me. Gulping one last time I simply replied;

“I’m all in”

As quickly as her glare had come on, like rain clouds on a hot day it disappeared and was replaced with a bright almost blinding smile. She lifted me and the groceries off the floor and pulled us wistfully down the hall. She pushed me into the open door way and into mum and dads room.

It was a sprawling open plan room, wide double doorway and a glass back wall that overlooked the entrance to the house. Next to the king size bed we could see the car we pulled up in.

Abby flung open mums side drawer and fondled through her things. Moments later she revealed a big black dildo with a curved end and a heavy flat base for batteries. Clicking the button the hulking beast jolted to life and buzzed in her hand. Abby threw the pulsating member onto the bed and reached into the grocery bag throwing the cucumber on the bed too. I watched impartially as Abby tore her clothes off and threw them into the door way, she lay down on the bed, sprawling across it giving me a picture perfect view of her gorgeous wet Pussy.

With her left hand she grabbed the still vibrating black dildo and slid it into herself, her pussy already insanely lubed and begging for the vibrating sex toy. Her mouth opened wide as noiseless moans left her lungs as the thick dildo shook violently on a high setting inside her.

Like a little bitch boy I lowered my pants and began folding myself, unsure of what to do except watch. Like the cuck in the corner I got myself hard as Abby played with herself using mums toy. The taboos just kept coming and I hoped I would too. As I stroked, I could feel my heart beat in my veins, I saw Abby with her free hand curling her finger indicating for me to come closer. I let go of my dick and walked over to the bed. In a whisper she began giving me firm directions;

“Take it out…slowly.” She said gesturing to the still shaking dildo. I subtly slid it from her grippy vagina, pulling it out to reveal the soaked toy.

“Now slide that cucumber in my wet, warm pussy.”

“But that’s for dinner!” I said caught off guard

“I know…that’s the point” she said her eyes rolling back in her head partially as she rubbed her clit.

I did as my goddess asked and slowly slid it in, taking care to read her queues of enjoyment. It was much thicker than the dildo and almost appeared to stretch her out. She moaned loudly as I pushed it deeper.

“Help me onto my stomach.” She said.

I placed my hands on her hip and upper back and slowly rolled her from her back onto her stomach careful to keep the thick Pussy stretching cucumber inside her. Now she lay stomach down, her perky cheeks staring back at me.

“Spread my cheeks.” She ordered, pushing herself to a slight all fours position. I grabbed each cheek in my hand, the warm firm cushions caused my dick to drip thick droplets of pre-cum.

“Get the dildo and shove it in my ass!” She ordered once more. Complying immediately I took the vibrating black dildo and slid it into her asshole.

Chase had stretched her booty wide as the dildo slid in ever so smoothly. I stood back momentarily viewing the puddle of pleasure in front of me known as my sister. She moaned deeply into mum and dad’s sheets as the dildo vibrated quickly.

I began to stroke myself watching my sister be double penetrated by my mothers dildo and food for dinner. It was so extreme, so taboo so erotic that I felt like I may collapse under the immense pleasure that tantalised every nerve in my body on fire. I sped my strokes up but it wasn’t long until Abby cried out;

“Fuck me Jakey, oh Daddy I need you I crave you.”

“But you took the plan B on the car trip home!” I said knowing full well I’d blow my load in her again if given the opportunity.

“I want to feel you up my ass, fuck my tight little hole Daddy.”

Taking the dildo out of her ass I threw it to the floor and replaced it with my own member. As I slid in she wailed loudly “OH Daddy you’re so thick, FUCK”

I rammed deep into her my strokes deep and purposeful. I noticed that with her free hand she had propped herself up a little more and was fucking herself using the cucumber, moving it in and out of herself to the tune of my strokes. My balls slapped up against her and I felt the power build inside me. As I listened to her moans and became lost in the rhythm my eyes caught a horrid visages; my parents pulling up in their car!

“Abby! Mum and dad pulled up they’ll see us!” I said trying to slide out.

Suddenly Abby’s hand released the cucumber and grabbed my dangling balls. She squeezed them tightly, buckling me over her, as her sharp red nails dug into my sac. The pain of the ball squeeze with the pleasure of fucking her ass was an unexpected and enthralling experience. Through the pain I heard Abby say;

“You’re either in or out which one is it?” She said tightening her grip.

I looked over to see mum and dad step out, not looking up but headed for the front door I hadn’t locked!

Abby squeeze became almost unbearable as the ecstasy pressure built to a head.

“I’m in. I’m in. OH FUCK IM IN!!!” I screamed as I blew a thick hot load down into her ass. Abby screamed with excitement “That’s it Jakey fill me up. Oh yes just like that.”

As I pulled my cock from her ass and fell to the floor trying to get dressed quickly. She rolled onto her back pulling the cucumber from her pussy; it was covered in a thick layer of her juices and sexual discharge. She stood up just as fast, my cum falling out of her ass onto her crop top. She grabbed her now cum stained clothes and tossed the cucumber in the grocery bag. She kicked the still vibrating dildo under the bed and took off, clothes and grocery bag in hand. Following suit I grabbed all evidence and ran to my room. No sooner did we hear;

“Kids were home!” My mothers instantly recognisable accent chimed.

As our parents made a commotion in the living room and kitchen I redressed and, when I thought all evidence of semen and sex was gone I stepped out of my room in a button up shirt and long pants alongside a pair of house slippers.

As I opened my door I saw, across the hall in Abby’s doorway that Abby just standing there wearing her oversized college sweater she got at the open day and her iconic two pigtails. I walked up to her and saw her lift the grocery bag. She pulled out the still dripping cucumber and forced all into her mouth gagging on it. She made a loud slurping sound and sucked the juices off of it before tossing it back into the bag.

My mouth dropped open in pure awe as she flicked her pigtailed head in the direction of the kitchen and began walking down the hall, I heard her call from in front of me to our parents said in her signature upbeat good-girl tone;

“Hey mum and dad, do you like cucumber in your salad?”
