They weren't bluffing!

Ava and I glance again at each other, neither of us believing what was happening right now. Like a parent forcing their kid to smoke a pack of cigarettes after catching them with one, it appeared as if Mom and Dad were going to discipline us with more of the same.

They had to be bluffing. This had to be a ruse. This couldn't be happening. This was meant to scare us, they'd pull the plug any second now...surely!

My father peels the shirt from his chiseled torso and tosses to the floor. Even though he was twice my age my Dad's physique was everything mine wasn't. He was a natural athlete who worked out, swam regularly, and was just generally active. Beach volleyball, basketball, you name it. His body was lean, muscular, and well shaped. His shoulders were wide, his chest was thick and defined, and his body tapered down to a trim waist. The hint of a six pack could be seen beneath his tanned skin. Unlike my own sparse patches of wispy red body hair Dad's torso was clean of such things. He kept himself shaved, which only acted to accentuate his impressive musculature. Being half Polynesian he had the dark hair and eyes of his father's side of his ancestry.

My mother unbuttons the cuffs of her work blouse and tugs off her own shirt. My eyes widen and my heart skips a beat. She was every bit as impressive as her husband. A Celtic warrior princess alive and well in the modern world. She stood as tall as I did and had a long sleek shapely body. She wasn't "cute", like Ava, she was smoking hot! Long curly red hair cascaded over her shoulders and down her back. Her skin was pale and smooth, the speckling of freckles across her chest, shoulders and cheeks only worked to brighten her beauty. Like her husband she kept in good physical condition...and sweet Jesus did it show!

Time nearly stood still as Mom then reached behind her back and unfastened her bra. The undergarment falls from her body in slow motion as I watch two perfect breasts spill into view. Not nearly as big and heavy as Ava's, but flawless in shape and symmetry. Her angry eyes drill into me and I knew I ought to turn away...but I couldn't help myself. I just kept staring.

Off to my left I am vaguely aware of the zippp of the fly to my father's jeans coming down.

I continue to gawp slack jawed at my mother until I hear my sister's surprised gasp.

"Oh...OH!" Ava says. "Oh Dad, oh my! Oh wow!"

I cannot help myself but to look over. My father stood at the side of the bed with his fly down and his cock hanging out in front of him. I wasn't stunned by what I saw, I had been in change rooms with my Dad many times, but Ava was...spellbound! Dad wasn't even close to hard and his cock already dwarfed my own. Nearly as long as mine was when it was fully erect and way WAY thicker.

Ava looks up to our father's face...and smiles. "Oh Dad! I never knew!"

"Suck it!" He commands her with a deep stern voice.

"Yes Father!" She sighs.

"Wait!" I cry out.

The room goes quiet and all eyes turn to me.

"Wait, please." I plead with them. I loved Ava and these past few months have been the happiest of my life. I didn't my fragile ego to take this. "Wait, you don't need to do this. We swear. We swear! We won't do it again. Isn't that right Ava?"

Ava looks from me, to Dad's cock, then up to his face. She blinks her big brown eyes and say in the most adorable little voice. "I think I need to be taught a lesson." With that she opens her mouth and hurries across the mattress to suck her father's thick meat into her plump lips.

My heart breaks. No Ava...no! What about us?

For my sister it was only ever about the sex. I had held out hope for more, but it was a fool's hope.

I blink my tears away and tear my eyes from them.

My mother however knew me better than anyone else. She saw through to the pain in my heart and she used it against me.

"Awwww, what's the matter hunny bunny?" She says in a sneering way. She sits down on my thigh, somewhere along the way she had removed her skirt and she now only had on panties and pantyhose. Reaching down she grasps my dick, her long fingers easily reaching all the way around. She begins to stroke my still half aroused manhood. "Don't you like seeing your sister sucking a real cock?"

I lower my eyes and don't answer.

"...mmm...mmmmmm...MMMMM..." I hear from the bed. Despite my shattered heart I glance over.

Father had sister by the hair as she sucked and bobbed on the front half of the nearly hard shaft. Despite trying her best Ava could only get half of him into her mouth. He had to be nine inches long and triple my girth. Having watched her easily take me right to the base and seeing her mouth barely fit around his enormous schlong it was a humbling reminder of my shortcomings.

My mother chuckles. "Well, that got you good and hard! Didn't it you little beta bitch?"

"No." I grumble. I convince myself that it was her stroking hand that had me hard enough to cut glass.

With a cruel smile she commences to crawl up onto me. She forces her legs into the space between my legs and the arms of the chair we were on which in turn forces my legs together. Her hands on my shoulders she settles herself down, the sheer nylon at her crotch pressing hard down into my skinny pecker. I reach up to push her away but she simply presses my arms down into the arms of the chair. I grip the arms of the chair and my eyes roll as she starts to grind against me.

"Mmmmm! Mmmmmmmmm!" I hear my sister hum hungrily on her dad's big dick, though I couldn't see them any longer with my mother's trim body writhing in front of me. I hear her slurp off the tip. "Shhhlrpp! Ohhh god Daddy! It's so big!"

"Did I say you could stop?" He growls back at her. "You wanted to be a family fuck toy? Well you got your wish!"

"Ohhhh Daddy!" She sighs dreamily before you hear a hard near retching gurgle as her mouth and throat are filled again, much deeper than before.

Your Mom glances over her shoulder. "Shit, can't our little girl deep throat?"

Dad laughs. "She'll learn."

She looks back to you then down to your smashed together groins. She grinds harder and faster. "Guess Ava never needed to go deep throat with you, huh Aiden?"

"Stop it!" I gasp. The sheer silky pantyhose rubs...rubs...rubs...incessantly. Every time I tried to shift she would pin me down with her weight. Ohh fuck did it feel good! "Stop!"

She grinds her nylon covered cunt even harder and even fast. "Stop what? Huh you little sister fucking piece of shit? Stop what?"

My muscles were tensing, my grip white knuckled on the arms of the chair. "MOM!" I grunt.

She buffets my face with her right breast and then her left. Her tits were so soft and warm and beautiful! "Are you gonna cum already you little wimp? Huh? Are you getting ready to cum? Daddy and Sis are just getting warmed up..." As if on cue you hear another gagging sucking noise coming from the bed. "...and you haven't done shit for me yet boy. Don't you dare fucking cum yet!"

I hear Ava's voice come to my defense. "Don't tease him Mom, he can't last...GLLLRRRGGG!!!" Her voice is cut off abruptly as father roughly jams his manhood back into his naughty daughter's open maw.

"Never mind them fuck toy, you got a job to do. Suck that cock slut!" Your Dad barks.

"Mmmmmmm!" She sucks and slurps with wild abandon, her lewd noises telling you this was not against her will.

Something about that, something about the thought of my sister sucking our dad's big thick schlong, sends me over the top.

"UNNNGHHHHHH!!!"

"Ha ha ha ha!" My mother laughs mockingly directly into my face. "Aiden loves this! He loves what is happening! He loves his sister sucking a real man's cock! Ohhh honey, I think our son is sissy little cuck! Ha ha ha ha ha!"

My father chuckles along with his wife.

"UNGHH!! UNGHHH!!" I shoot my load between my mom and I's pressed bodies. She doesn't let up one iota as the creamy wads belch out of my slender dick. The crotch of her pantyhose quickly becomes shiny and milky with smeared jizz. "Huhhhhhhhnnnnnn!" I groan as I tremble in release beneath her.
