Sally is sprawled on the kitchen table, Tommy ramming into her from behind. Her brain and body are on fire with incestuous lust, and she knows something alien and intelligent has taken her over. God help me ... I fucking love it! “Fuck me, Tommy! Oh my fucking God, I think we’re demon possessed!”
“I can’t fucking help it, Mom!” Tommy yells, gripping her huge tits. I gotta fucking cum inside you!” He knows there is another son-being inside of him, giving him an erection and vitality he has never had before.
“Do it, you baby! Give mommy all your hot fucking incest cum!” Sally’s mind and body go into pleasure overload as she climaxes harder than she ever imagined. He body bubks and thrashes as she takes her son’s incestuous cumloads inside her maternal womb. She feels another mother attached to her brain and body, knowing she is experiencing the orgasms through and with her.
She sees, through lust-glazed eyes, her husband and daughters enter the kitchen naked and smiling. Even in her sexual rapture, she can see their bodies are perfectly smooth except for head and facial hair. Her husband’s cock is much longer and thicker and she feels a perverse thrill watching them fondle each other. She smirks as she begins to come down from her fuck high, knowing they are possessed, too,
“I can’t stop fucking Mom, Dad,” Tommy grunts, continuing to pound into her. “She feels so fucking good!”
“Give it to her, Tommy,” James chuckles, wallowing in the perverse sight. “She loves it and wants it, right, honey?”
“Yes! Yes! Oh my fucking God, it feels too fucking good to fucking stop!” She begins driving and grinding against her son’s throbbing cock inside of her. “Ooh! It feels so fucking good saying ‘fuck’!”
“I wanna see Tommy fucking Mom, Daddy,” Kylie tugs James’ cock, leading him to where she can feast her eyes on her brother’s fat cock thrusting inside their mother’s smooth pussy. Kylie presses her open mouth over Tommy’s, and they tongue kiss as she fondles his ball sack.
James moves so that he can fuck his daughter as she pleasures her brother. “Praise God for incest!”
“Praise the fucking Lord!” Sally moans, looking over her shoulder at her perverse family and loving it.
“Eat Daddy’s cum from my pussy, Mother,” Kayla demands, lying on the kitchen table with her legs spread. She grabs her mother’s head and pulls it into her wet, sopping snatch. “Fuck yeah! This is what these bodies are about,” she moans, grinding her pussy on Sally’s mouth and face.
“Goddam! I don’t know what the fuck has taken us over but I fucking love it!” Kayla yells, looking at her incest crazed family.
“It might be aliens or it might be demons,” James grunts, fucking into his daughter, Kylie, playing with her meaty teen tits. “I only know my body is a vehicle for whatever the fuck has mutated us, praise God!”
Kayla’s pussy is scentless and perfectly smooth. Sally realizes they have become more synthetic than human and are being used as pleasure vehicles for something not human. She knows it is a mother energy being of some kind having incest with her energy son through her son, Tommy. They have now become sterile and possibly immortal.
Kayla grips Sally’s head and grinds harder than ever as she squirts and gushes all over her mother’s mouth and face. “Take it, Mother! Oh, fuck! Cumming so fucking hard!” She bucks and squirms on the kitchen table, screaming.
Sally’s gorgeous MILF faced is dripping with her daughter’s squirt as she looks over her shoulder at her son, Tommy, licking his sister, Kylei’s tongue. “Give us your fucking son-cum, you motherfucking instrument of our maternal fucking lust!”
Tommy grunts like a beast, gripping his mother’s hips as he floods her cock crammed cunt with load after load on synthetic teen jizz. Yeah, Mom! Fuck yeah! Synthcest is fucking best!”
“Daddy, Daddy, Daddy!” Kylie squeals as she gushes ersatz pussy lube all over James’ fat cock.
James grips Kylie’s hips hard as he sends stream after stream of sterile cum inside his daughter’s cock clenching cunt. “Yeah! God is fucking good!”
As the family begins to come down from their mutual fuck high, the energies inside them stimulate their mutated bodies and minds again.
“Let’s go upstairs to the master bedroom and have another family fuck,” James growls, pulling out of Kylie’s dripping pussy.
“Yeah! I wanna fuck Mom while she wears that slutty garter outfit she wears for you, Dad,” Tommy says, pulling out of Saly’s cum drenched cunt.
Sally chuckles, looking at Tommy. “I’ll wear anything you want, baby! I’m your incest cum dumpster MILF mom!”
“Let’s fucking go,” Kayla says, sliding off the kitchen table. “I wanna fuck my brother’s fat dick and dad’s at the same time!”
“Let’s race,” Kylie giggles, running out of the room, ersatz cum fluids running down her thighs.
“Yeah, Mom,” Tommy pants, watching Sally putting on her garter in the walk-in closet. He grabs her and pushes her onto the floor. “I can’t wait, Mom! I gotta fuck you now!”
“Ooh, I guess my baby is too horny for his mother’s pussy,” she chuckles as she spreads her stockinged thighs. She groans as he shoves his bloated cock inside her, lighting up her mind and body with incestuous energy.
They kiss open mouth as they hump and ground on the closet floor.
Kayla rides her dad’s fat cock, reverse cowgirl, watching her mother and brother. “Give it to that horny bitch, bro! Fuck! This is so fucking sick!”
Kylie rides her father’s face, looking over Kayla’s shoulder at her mother and brother fucking on the closet floor. “Yeah, bro! Praise the Lord for incest!”
James eats and fingers Kylie’s wet grinding pussy on his face. Their filthy outbursts feed the alien father inside him, driving him to fuck harder into Kayla’s synth-pussy.
“I can feel her inside me,” Sally moans, driving her maternal pussy as hard as she can on her son’s plunging cock. “I’m gonna cum so fucking hard, baby! Ooh!”
“I know, Mom,” Tommy grunts, sucking on a nipple. “He wants me to cum inside you!”
“Do it, Tommy! We may be synths but we’re still fucking family! Ooh,” Sally whines.
Tommy grips his mother’s ass cheeks as he floods her maternal womb with sterile loads of cum.
Sally wraps her legs around him even tighter as her pussy creams around his jizz spewing cock. “So fucking good! These bodies are so fucking good!” She sobs and wails, climaxing harder than ever.
Kayla screams and squeals, bucking and thrashing on her father’s cock as she climaxes watching her mother and brother cumming together on the closet floor. “Prasie the motherfucking Lord! Fuck!” She yells, clutching James’ ankles as she rides him reverse cowgirl.
Kylie braces herself on her sister’s shoulders as she sobs and squeals, gushing and squirting all over her father’s mouth and face.”Fucking incest! Prasie God for fucking incest! Ooh!”
James hangs onto Kylie’s hips as she grinds her pussy on his mouth and face and his swollen cock sprays Kayla’s tight wet pussy with cumloads of infertile paternal slime.
“Gotta have more, Mom,” Tommy groans, pulling out of her well-fucked pussy. “Gotta cum in your ass, too!”
“Do it, Tommy,” Sally moans, lifting her legs so her thighs are on his shoulders. “Pound mommy’s synth-ass with the huge cock of yours!”
Tommy shoves his cock inside her ass tunnel, pumping in and out of her hybrid body.
They glare at each other with animal lust, driven by the alien mother and son inside them, as they grind their bodies together.
“Fuck my ass, Daddy,” Kylie demands, lifting her pussy off his face.
“Yeah fuck my ass, too, Daddy,” Kayla whines.
“Both of you in front of me on all fours on your elbows,” James growls. “Just like in your bedroom!”
