Down the street of Central City....
Iris and Caitlin were driving down the road, heading home. In the backseat sat four girls; their daughter Nora, Nora's and Caitlin's future twin daughters Chloe and Courtney, and finally Nora's and Kara's daughter Loriane. The six women were all very happy to be together again.
Caitlin smiled at her wife Iris. Iris smiled back and drove the car. They then stopped at a red light. Iris then proceeded to unbutton her own pants and pulled them down, revealing her cock. Caitlin smiled and began to suck on Iris's dick.
As they drove down the road, they were listening to a radio interview between a news responder and two doctors from Central City Hospital; Dr. Manning and Dr. Reese. The interview was about the measurements of cocks.
"So," the news responder said. "You said that the measurements of cocks has changed. How much?"
Natalie chuckled. "In 2014," she said. "We measured the cock lengths and girths of up to 15,521 males and futanaris aged 18 and over. We then compiled them into one document and the average measurements were as follows; A flaccid penis length: 9.16 centimeters, or 3.6 inches when stretched. A flaccid penis girth: 9.31 centimeters, or 3.66 inches. An erect penis length: 13.12 centimeters, or 5.16 inches. An erect penis girth: 11.66 centimeters, or 4.59 inches."
The news responder paused. "So," she said. "What about your recent study? What did you find out?"
Dr. Reese chuckled softly. "The difference between the length of erect minus flaccid," she said. "5.16 inches minus 3.6 inches, 1.56 inches has not changed. Neither has the difference between the erect penis girth and flaccid penis girth, 0.93 inches. Nowadays, we believe that despite the large increase in the length and girth of futanari women's cocks, these two numbers are still the same as in 2014."
Thank you so much, Dr. Manning and Dr. Reese," the news responder said. "We'll talk more about this study, and the other things about them after the break."
Iris smiled and changed the channel to music and began to hump Caitlin's mouth as the bioengineer gave her road head.
Meanwhile in the backseat, Nora and the other three girls were making love with each other. Nora was getting her tits sucked on by Chloe and Courtney. Chloe was sucking on the left nipple and Courtney sucked on the right nipple. Loriane was kneeling in front of Nora, giving the young speedster a sloppy blowjob.
Nora moaned. She reached down and began to stroke Loriane's head. With a muffled groan, Nora came hard, spurting her futa spunk deep inside Loriane's mouth. The four teens then rested together.
Iris smiled and began to hump Caitlin's mouth as the bioengineer gave her a blowjob. "Oh yeah baby," Iris said. "Suck my cock. Deepthroat it all down your throat. I want to feel your tonsils against my cock."
Meanwhile, in the backseat, Nora was giving cunnilingus to Loriane. The young speedster/Kryptonian hybrid moaned as Nora's tongue grazed her pussy lips. "Ohhhhhhhh fuuuuuuuuuuuuuuuuuuccccckkkk," Loriane moaned as she felt Nora's tongue graze her inner parts.
Nora plunged her face into Loriane's cunt and slurped on it. She knew she was doing good because of the whimpers of pleasure that Loriane was muttering. Nora pulled away and smiled. "I wanna fuck your cunt," she said.
Loriane smiled. "Then come over here and fuck me baby," she said.
Nora smiled. Loriane smiled as well. When Loriane was on the top, the quality depended on her. But, If Nora could adjust properly, the young speedster could dominate with the depth of penetration.
Nora sat on the seat and laid back against the backrest. Loriane smiled, climbed on top of Nora's dick, sat down, and faced Nora. Loriane moaned as Nora's dick entered her young snatch and nestled inside her womb. Nora smiled. She placed her hands on Loriane's breasts. Loriane whimpered in pleasure and placed her own hands on Nora's chest.
Nora moaned as she began to fuck Loriane. She pinched Loriane's nipples and twisted them. The pain and pleasure grew more intense for the young metahuman hybrid. Loriane rocked her head back and screamed as she came, squirting her juices all over Nora's dick.
Nora then followed suit, spurting her futa spunk deep inside Loriane's snatch. Nora grunted as she pumped load after load of futa spunk inside her future daughter's snatch.
Every single thrust struck Loriane's g-spot. She wrapped her arms around Nora and rested her head on the young speedster's shoulder. She whimpered softly as Nora pounded her snatch hard and deep.
Finally the two girls came hard, spurting and squirting their respective cumshots together. Loriane panted in pleasure. She never thought she would orgasm that much. She lifted her head up and looked into Nora's eyes.
The two girls then kissed each other passionately and fondled each other's bodies. After a while, Loriane rolled off Nora's cock and sighed deeply. "That was amazing," she said. "Mom, you really do know how to fuck your daughter."
Nora smiled. "I'm glad you liked it," she said quietly. "But, don't tell anyone about it. I wouldn't want Naomi finding out that I had sex with my future daughter."
Chloe smiled as she crawled in front of Nora. "Oh yeah mommy," she said quietly and sarcastically as she stroked Nora's cock. "I'm sure Naomi cares about you having fun with your daughters."
Nora nodded. Chloe smiled. They were then getting into position. This pose gave plenty of scopes to derive pleasure out of penetration and an electronic device is there to add some more spice into it.
Nora smiled as she laid back against the backseat comfortably. Chloe smiled as she came over, and sat on Nora's groin to get into the position. Chloe was facing away from Nora. Nora watched as Chloe slipped Nora's cock into her young snatch and began to hump her slowly, but deep. Although penetration is deeper, the use of vibrators manifolds the pleasure.
Nora and Chloe moaned as the young speedster fucked the young metahuman's cunt. Nora pulled out and repositioned herself and Chloe.
Chloe leaned up slightly against the driver's seat, bumping Iris.
Iris glanced back so Chloe said, trying to act casual even as her mind was turned to mush, "Sorry, just changing positions."
"I'm sorry about this situation," Iris apologized.
"It is what it is," Chloe replied, not blaming her future mother, as she felt Nora's hands on her hips as Nora lowered her back down onto her own lap and... and right onto Nora's hard cock!
Chloe yelped in pure unadulterated pleasure and Caitlin asked as she turned down the radio, "You okay?"
"Yes, I just got poked by something in a box," Chloe responded weakly, unable not to say something naughty, an amazing pleasure coursing through her body as her future mother's cock, which she now had excellent reason to know was bigger than her own girlfriend's, was buried deep inside her, Nora's hands firmly on Chloe's hips, holding her in place.
"Okay," Caitlin nodded, as she turned the radio back up as another eighties tune, Bryan Adam's 'Summer of 69', began.
Chloe just sat there; still in complete shock that her mother's cock was buried deep inside her cunt, anchoring her in place.
She just sat there; the urge to start riding her mother's cock growing with every second it remained inside her.
Chloe just sat there; wondering what her astonishing mother was going to do next.
She just sat there; secretly wishing Nora would take even more control.
Chloe just sat there; worried that if Nora did take control, she would be unable to conceal the obvious reality that they were committing incest just inches away from Caitlin and Iris.
Chloe just sat there and... judge her if you must... enjoyed the ride, every bump in the road giving her fresh pleasure as Nora's cock surged up inside her. Chloe had to use all her will power not to moan, not to alert Caitlin and Iris to the incestuous adultery she was committing and she couldn't deny, committing willingly.
