The Change. By dmaynard A young woman expriences an erotic FMG scene, and destroys her Father while having fun with her "big" brother. Over 18 only plz! Huge muscles burst from her tight clothing, covered in veins, the golden tinted mounds of rock hard flesh split through the fragile cloth like paper. Meaty forearms attached to steely mounds of bicep muscle arched upward in a dramatic flex. The woman watched in pure glee as the gargantuan muscle mass of her arm hardened and expanded to an amazing size. Muscled pecs surged forth from her chest, huge bands of female muscle popped buttons and split fabric easily. Nipples protruding like bullets seared through the shirt, as a vast channel of hard muscle flesh formed. She screamed in pleasure as her abdomen resurfaced itself with rippling armor plates of tanned muscle, channeling itself into her crotch with a distinct "v" of hard flesh. Her skin-tight jeans burst from the pressure of trying to contain her massive thighs. Ripping the jeans to shreds, diamond hard calves and thick rippling thighs made short work of the denim. Her leg muscles ballooned out so thickly, her tiny pink panties barely concealed the entrance to her dripping pussy. Staring down from her almost 9ft height was a tiny average man, quaking in front of the goddess that had sprung up in front of him, which was moments ago his tortured little sister. Smiling, she leaned forward slightly and produced a most muscular pose that made her brother piss his shorts in fear. Her tiny innocent face was surrounded by bulging rock-hard muscle as pecs and traps flexed in a frame about her head. "Guess you shouldn't have treated me so badly now, do you?" She reprimanded him. "Hey, what's that in your pocket?" Her brother looked down, and noticed he was sporting a tremendous erection at the sight of his sexy Over-muscled little sister. He fought both shame and manhood in a vain attempt to control himself. Picking him up by his shoulder, big brother wiggled in her grip while she grabbed his shorts and painfully tore them from his body. His erection flopped in the open for all to see. "Haha! I can't believe I gave you a hard-on, and I'm your little sister to boot! I think you like it though, I think you like having a a big, sexy, well muscled 'little' girl have her way with you, don't you?" she teased her big brother relentlessly, all the while stroking and fondling his massive hard-on. "I'm...I'm...so.....sorry" he gasped as little sister stroked his cock with her meaty hand. "I'll bet you are...you like having something hard handle your little prick eh? Here...I'll bet you'll like this then..." smiling, she gripped her brothers buttocks and flexing her chest muscles outwards, plunged his rock solid cock into the channel of muscle cleavage that had formed upon her chest. "Goood....God" he moaned as he felt his dick be massaged by the rippling chest muscle of his little sister. It wasn't long before Big Brother furiously began shoving his hips back and forth, fucking his little sister's muscle cleavage. Little sister watched in pleasure as her brother pumped his cock relentlessly into her thick chest muscles. "That's right big bro, pound that dick into my hard chest! You feel it big brother? You feel my muscles around your hardness? You want to cum don't you? Cum on my big, hard, chest...." Little sister effortlessly held her brother as she squeezed her chest muscles around his pounding cock. "Uhhh....UHHH!!" Big brother moaned as felt his orgasm rising, his sensitive cock rubbed furiously against the steely bands of little sister's chest muscles. Before he knew it, he felt his cock explode into her muscled channel of cleavage, plumping load after load of hot semen onto her flexing pecs. "What the hell is going on in here!?" The two siblings looked in shock at their fathers awe-struck face caught in the entrance to big brothers room. Little sister's look of shock quickly faded into one of anger. "I'm having fun is what's going on in here daddy!" She threw big brother onto his bed, his spent cock dripping with fluid, and advanced towards her dad. "What the hell? What are you?" daddy yelled in fear as his daughter's large hands grabbed and lifted him several inches off the ground. "What am I? Someone who is going to teach you a lesson." Her face was crumpled in irritation, as she was annoyed by a fly for all the squirming her father was doing. Her father watched in horror as his gargantuan daughter smiled an evil grin and she glanced down to notice that her father had also sprung an erection. Little sister gently ran her fingertip over the bulge in daddy's pants. "Not bad daddy, but I have a surprise for you." She laughed a little as her father heard some soft tearing sounds coming from below his daughters waist. Both big brother and daddy watched in genuine horror as little sister's tiny pink panties began to stretch outwards, erupting from within her well muscled pussy a hard meaty cock began to shove it's way out. Arching strongly upwards, the princk snapped the panty easily leaving her massive hard-on to bulge outwards threateningly. Cum filled balls, the size of ostrich eggs, flopped out beneath her hard princk shaft. "Surprise daddy..." Little sister whispered in her father's ear as the dad quaked in fear. She flipped her father around and once again, painfully tore his pants and underwear off almost effortlessly. "This will hurt me more than it will hurt you...haha! Just kidding!" Little sister plunged her father down upon her raging princk, stretching his tender asshole to untold of limits. Her father screamed in agony as the mighty cock was hard enough and big enough to hold him against little sisters chest as she flexed her mighty guns, each golden boulder of bicep swelling twice the siZe of his head. Daddy continued to scream as she held onto his shoulders and pumped her massive appendage in and out of her fathers backside. Flesh could be heard tearing, bones could be heard breaking as her fathers' insides contorted to make way for the muscled princk that fucked his ass with amazing power. Steel cannonabll glutes scrunched up with amazing strength as they plowed in and out of her fathers fragile body. She pounded into him for several minutes, snapping ribs, cracking his backbone, and squashing his internal organs. His screams died down into barely audible whispers as little sister became bigger and harder with each thrust. "Goodbye daddy!" She whispered as she gathered up her father into her massive chest muscles and gave him a suffocating bearhug with her tremendous arms. Big brother watched in vain as little sister continued to pound into her dad, who's head, slowly but surely began to disappear within a massive convergence of chest muscle. Finally, after several agonizing minutes, a humongus orgasm exploded from little sister who's entire body reacted to the explelling of her female princk spunk into her father's body which had become little more than a meat sack. Distinct crushing sounds indicated his head was imploding under the pressure of her massive chest, which had ballooned outwards so greatly the tops of her pecs muscles bumped against her chin. Biceps crushed his upper body into itslef, making little sister's upper torso look and sound like a car compactor. Bone snapped and broke as hard muscle flexed with the writing fury of her orgasm. Traps exploded near in size near her head. She flexed so hard the crushed flesh and bone of her once father oozed from the seams of her hard muscles. Blood and other bodily matter spurted from her physique in powerful streams. When she finally relaxed, it looked as if her father had been placed in a garbage compactor and squeezed until nothing recognizeable remained. What parts of him slid off her flexed form onto the floor in a pool of reddish liquid. Big brother watched as the mighty cock that sprung from his sisters crotch defalted and returned back to the inside of her muscled pussy. "That. felt. GOOD!" She exclaimed. She turned to face her big brother. "Let's have some more fun like that..." Big brother swallowed hard and prepared to die.
