Kay, Jared, Kat, Leo

Kay pulled her BMW into the four-car garage attached to her spacious home in the gated community. She exited the car and noticed some neighbor boys on bikes ogling her as they pedaled down the street. She smiled, bending over just a little more than needed to get her purchases out of the car.

She carried her packages through the spacious house and deposited them on the cherry wood kitchen table. I have to keep the hubby happy, she said as she sorted through the luxury lingerie. There are a lot of young cats out there who would love to sink their claws into my resources.

The doorbell chimed, and she looked up, touching her blonde hair as a reflex. She went to the double front doors and opened one. There was no one there, just a cardboard box. That was quick. She carried the box to the kitchen, inspecting the sender’s address: S.I. Labs?

She opened the box with a stylish letter opener and looked inside. At first, she was puzzled, then realized they were VR headsets. She took them out of the plastic sleeves and examined them. They were silver and almost weightless. Each one had a name on addressed to her family: her and her husband, Leo, and their kids, eighteen-year-old Jared and nineteen-year-old Katarina, or Kat for short.

There was a note inside: Congratulations! You have been chosen to test our latest beta VR headsets! Place the one with your name on it, and it will take you to an SI dimension! Kay frowned. SI? She carried the box and her bags up to the master bedroom overlooking the lake.

She sat against the cushioned headboard and examined the headset with her name on. She had tried one of her son Ian’s VR headsets and found it gave her a headache after a while. She put it on and waited.

Her arms were outstretched as she braced herself against the headboard being fucked hard from behind. “Oh God! That feels sooo fucking good, baby,” she groaned. She knew it was not her husband fucking her as the cock was huge, stretching her vaginal walls to the max.

She pulled off the headset. Her heart was beating fast. Her entire body was aroused. Her panties were damp. Is this a self pleasuring device? She looked at the clock. No one would be home for a while. Guilty pleasures. She put the headset back on.

“Goddam, you’re so fucking huge,” she gasped as the meaty cock hammered in and out of her pussy from behind. There was something familiar about the hands that gripped her meatier tits. “Ooh, my fucking God! You know just what mommy needs,” she moaned as a tongue licked between her shoulder blades. Mommy? She didn’t care as the most thrilling orgasms she had ever had tore through her body and mind. Oh! Oh! Oh, my fucking God!” She screamed and sobbed as her entire body tensed and spasmed. She wailed and blubbered as her cock-stretched pussy gushed inordinate amounts of cuntal cream around the prodigious prick.

She felt his male body tense as he leaned over her, his strong fingers digging into her breasts as the enormous cock blew stream after stream of cock juice inside her. “Take my fucking cum, Mom,” Jared grunted in her ear. “Welcome to our fucking Synthetic Incest world! Uh! Uh! Uh!”

Kay felt a burning pleasure racing through her body and mind with every jolt of virtual cum spraying inside her virtual body. She felt another maternal consciousness merging with her mind and senses. An alien mind that was transforming her into its vehicle for incestuous pleasures.

“Enjoying the transformation, Mom?” Virtual Jared panted and whispered in her ear, his cock still rburied inside her.

“You fucking know it,” she chuckled, panting. They licked tongues, glaring at each other with feral intensity.

Kay yanked the headset off, panting. She slid off the bed and strode to the full-length vanity mirror in her walk-in closet. She stripped out of her blouse and bra, examining her breasts. They were perfect. The tiny skin tags she had by her collarbone had vanished. She looked over her shoulder at her back. The few moles she had were gone. She unzipped her skirt and pushed it down, along with her lube-wet panties. She peeled off her thigh-high stockings and posed in front of the mirror, marveling at her new body. Her pubic hair was gone, along with her armpit hair and legs.

She strode to her vanity table and sat. She turned on the lights and examined her face. No wrinkles. Her blonde hair was more luxuriant and full. She chuckled as she stood and bent over, pulling her ass cheeks apart, bleaching not needed.

She looked at the clock. Jared would be home from school soon. Let’s see how he likes his new mommy. And I get to have a son fuck-tool. She chuckled, walking back to her closet. She sensed she had become sterile and chuckled. What do I need as a Synthcest that I don’t already have?

She dressed in her form-fitting Pilates uniform, revealing her toned stomach, admiring herself in the full-length vanity mirror. My ass is perfect. Her breasts had grown, pushing out the front of her top, the cleavage pronounced.

She looked out the family room window, seeing his car pulling into the bricked driveway. She felt her vaginal walls secrete lubrication as she stretched out in a seductive, vulnerable yoga pose on her mat. She did not have to wait long.

“Hey, Mom,” he called from the kitchen. “Where are you? When did these VR headsets come?”

“I’m in the family room,” she called, stretching.

“Where did these come from?” He asked, entering the family room.

“I know as much about it as you,” she smiled, noticing how he was trying not to ogle her body. “I left the carton with the address and note because I thought you might know of a high-tech company that would manufacture such things.”

“You look different,” Jared said, looking down at her. “Younger.”

“It’s probably a new skin care regimen,” she smiled, loving how hard it was for him not to stare at her tits. “I tried my headset in bed. You know how dizzy I got when I tried your gaming headset.”

“What was it like?” Jared asked.

“Oh, it was okay,” she said, going back to her mat and stretching, knowing his eyes were on her ass.

“I gotta try it,” he said, walking away, holding the headset and his school backpack.

Kay smirked, watching his ass, her maternal pussy dripping with lube. He was a younger version of his father. Tall, athletic. Dark hair and those ice blue eyes. She called him Leo the lion when they fucked. Now she was going to fuck their son.

She licked her lips as she mounted the stairs to his bedroom loft. Her brain and body burned with the incestuous desires of a human and alien mother for their son. She sensed he would be enthralled by what he was experiencing in the Synthetic Incest world. She stood outside his bedroom door, listening. “Jerk it, Mom! Fuck! That feels so fucking good!”

Kay opened his door and saw Jared lying in bed, wearing the headset. His fists were clenched, and his body was tense from what he was experiencing in the SI world. Her lips formed a lascivious smile as she saw the crotch of his jeans bulge. She got on his bed and unzipped the pants, groaning as she pulled out the swollen teen cock.

The alien mother urged her from within. “Does my grown up baby boy want mommy to jerk the cum from his big cock?” She teased, jerking slow on the boated, throbbing shaft.

“Fuck yeah, Mom,” Jared groaned. I’m gonna cum so fucking hard,” he gasped and panted, his hips moving up and down.

Kay chuckled, watching the precum drool out of the cock slit, before several streams of teen jizz shot out, spraying in the air, splattering on his clothes, drooling down her hand. She kept jerking on the erect, slimy shaft as his body relaxed. She smirked, feeling the alien mother disgusted by the animal scent and feel of human cock-slime. She wiped her hand on his sheets as she watched his pubic hair becoming absored into his skin as his cock began to swell dramatically.
