Gina wanted her son, Finn. Her sister and the oil of incestuous corruption drove her mutated mind and body to one focus: seducing her son. She had no intention of following her nephew’s filthy little plan of bringing Finn into their incestuous group. She wanted him all to herself. At least for now, she thought, pacing by the upstairs bedroom bay window, overlooking the dark road.
She touched her blonde hair, adjusting her body-hugging pencil skirt and cleavage-revealing blouse. Her panties were wet, imagining how glorious it was going to feel when Finn penetrated her for the first time with his son-cock. Her heart leaped as a wash of lube flowed into her lace panties. It was he, pulling into the long driveway.
Her sister and her family were downstairs in the kitchen, ready to implement her nephew’s perverse plan. “I want him all to myself,” Gina stated. “Here’s what I’m going to do...” She said, taking a pitcher of oil from the counter.
Gemma chuckled. “Never interfere with a corrupted Boy Mom about to turn her barely legal son into a man!”
“Can we watch?” Elle asked eagerly.
“Give me a while to corrupt him,” Gina said, marching out of the kitchen with the pitcher.
Frank chuckled. “And I was taught girls are sugar and spice and everything nice,” Frank said.
“Yeah, Dad,” Gage said. “And we’re supposed to be the aggressive ones.”
Gemma laughed huskily, grabbing Gage, shoving her tongue in his mouth while grabbing his swollen crotch. “I’ll show you female aggression,” she smiled.
Gage cupped his mother’s ass through her pencil skirt as they licked tongues, glaring at each other with unnatural lust. “Fucking bitch,” he whispered. “You want it all the fucking time, Mom.”
“Born to be your mother, corrupted to be your lover,” she chuckled huskily, opening his jeans, a challenging snarl on her gorgeous face.
Gage sucked on his mother’s long neck, lifting her skirt with his hands over her waist, revealing her garter and stockinged legs.
Gemma moaned with sensual pleasure, hauling out her son’s bloated cock as he rubbed her wet maternal pussy lips.
Elle pushed Frank against the counter, dropping to her knees, unbuckling his pants. “You’re such a nasty old fuck, Daddy,” she giggled, knowing how turned on he got when she called him names. “You probably bought this cursed house just to fuck me,” she smiled, looking up at him as she pulled his meaty cock out of his pants.
“No, but I’m glad I did,” Frank chuckled, watching his nubile daughter licking the tip of his bloated cockhead. “Pull that tube top down and put those meaty teen tits to good use,” he growled.
“Like this, Daddy?” Elle giggled, pulling her tube top down, pressing his swollen cock between the teen twin globes, biting her lower lip.
Finn pulled up to the oversized detached garage behind the Victorian house, parking alongside his mother’s vehicle. He was anxiously horny to see his hot first cousin Elle. He sniffed the air, smelling his dead father’s cologne. He heard his father’s voice whisper in his ear, “Fuck your Mother, Son. She needs it.”
He watched his mother approach his car as he got out. “Hi, Mom,” he said, noticing a strange, twisted smile on her face as she approached him, holding an antique-looking pitcher. She walked sensually toward him, her heels clicking on the brick driveway. Her long blonde hair blew slightly in the wind. Her makeup was perfect, and she glowed with preternatural beauty. Her blouse was open enough, revealing a deep cleavage and meaty breast globes.
“Kiss her,” he heard his dad whisper in his ear as she moved her face close to his, her eyes glowing with desire. Her eyes bore into his, and he opened his mouth, entranced by the allure of her presence, the scent of her perfume ... She thrust her tongue inside his mouth, spilling the contents of the oil mixed with her saliva inside him. Finn felt a rush of blood rushing intto his cock, making the spongy tissue swell into rigidness. His head whirled with raging incestuous desire for this gorgeous woman who had given him birth. Her deep moans of pleasure made his cock throb painfully hard as they tongue kissed.
“Drink this,” Gina said, her voice husky with desire, handing him the pitcher. Her eyes never left his as he swallowed the delicious oil into his wildly fluttering stomach. It was empty. He dropped the pitcher and grabbed his mother. He held her tight, kissing her with tongue, sucking on her neck as they pressed their bodies together.
“Carry me inside the house and fuck my brains out,” Gina gasped as her son ravished her. “Oooh, through the side door, I want you all to myself,” she moaned as she wrapped her arms around his thick neck. “Your aunt, uncle and cousins have all been corrupted by the incest curse on the house and are fucking in the kitchen,” she said softy.
“Go this way,” Finn’s dad whispered in his ear as he carried his mother into the side entrance. They could hear their relatives going at it loudly from the kitchen as they passed.
“How do you know where to go, baby?” Gina whispered as he carried her through the spacious house.
“Dad’s telling me,” he grunted, carrying her up the grand curved staircase. “He told me to fuck you when I got here. He whispers in my ear.”
Gina sobbed. “He was so good at taking care of us. Of me. And now you’re my husband, baby.” They licked tongues as he carried her down the upstairs hallway, directly to the bedroom she was staying in.
He set her down, and they tongue kissed as they undressed, their eyes glowing with forbidden desire. “Dad says he wants you to ride my cock while I suck your tits, Mom,” Finn said, lying on the king size bed, his bloated cock, throbbing and leaking.
“Yes! Yes! I love fucking this way,” Gina said, straddling ove her son’s rigid cock, wearing only pull up dark stockings. “Oh! Oh! Sooo fucking good,” she moaned as she sank her wet maternal pussy over his cunt stretching shaft.
Finn played with her meaty breasts as he drove up into her. “Dad says he knows you cheated on him and he wants me to call you a fucking whore!”
“Yes! Yes! I’m a cheating fucking whore!” She yelled exuberantly as they slammed their fuck organs together. “Pull my fucking nipples,” she gasped.
Finn sucked on a stiff nipple, swallowing the thin, oily liquid that spurted into his mouth. He grabbed his mother’s hip as they fucked even harder in their incestuous cursed fury.
“Oooh, yeah,” Gina moaned, bracing herself on Finn’s sinewy shoulders as they drove against each other, his balls squishing against her inner thighs and ass. “I fucked your dad’s best friend, oooh, some guys from the law firm, and now I’m fucking you, baby! The hottest fuck of all! Kiss your whore-bitch mother, baby,” she hissed.
They pressed their mouths together, licking tongues and panting as they glared at each other with unbridled lust, fucking against each other ferociously hard.
Knowing her dead husband was watching her fuck their son made Gina even hotter. “What is your dad saying now, honey?” She groaned. “Does he like watching us fuck? Oooh!”
“He said he’s fucking you through me and the house, and he can’t wait to get you in the dungeon, you hot fucking incest whore, Mom!” Finn panted, slamming into her so hard she bounced like a rag doll on his cock. “Yes! Yes! We need to go to the basement, baby! You can punish me for my whoring sins!” She wailed. “Mommy’s gonna come so fucking hard, baby! Harder than ever fucking before! Yiiieee! Ooohhh! Fuck! Chriiissst!”
Finn held his mother tightly by her hips as she bucked and thrashed riding him, gushing maternal lube fluid all over his cock as he began discharging load after load of teen son-cum inside her. “Take it, Mom! Take all my hot fucking cuuummm!” He yelled, grimacing and snarling as his toes curled.
Gina passed out several times as she climaxed harder than ever before. She felt as if the energy of another male was coming inside her, and it had to be her dead husband’s energy.
“Am I a better fuck than Dad, Mom?” Finn gasped, still shooting cum inside her.
“Yes! Yes! Oh, God! You’re my fucking husband now, baby! Oooh! Fuck yeah!” Gina panted, collapsing on top of her son, commingled fuck fluids running out of her cock stuffed cunt.
“We should get married, Mom,” Finna breathed as he caressed her smooth back as she lay on top of him.
“We have to, baby,” Gina moaned, licking his bulging bicep.
“Let’s all get married,” Elle said, as the rest of the family entered the bedroom. “It’s so totally sick and hot!” She was wearing nothing but a tube top pulled down over her firm, teen tits, gripping her dad’s fat cock.
Frank was leering at his sister-in-law and nephew as they lay perversely in bed together. “We could do it in the basement dungeon,” he chuckled.
Gemme laughed wickedly, tugging on her son’s distended prick as he played with her meaty tits. “We need special wedding rings, hiding from the world what sick incest fuckers we are!”
