His new daughter, Jessie

Jessie was the first to reach her father, tackling him to the mattress. She made short work of his pajamas, tearing the loose fabric apart.

"Mmm, daddy, you look so yummy," she said, eyeing her father's twitching dick. "Mind if I have a taste?" she asked, immediately sucking the growing length into her mouth and looking up at Hank with pleading eyes as she bobbed up and down. She groaned in pleasure as he hardened, unable to resist the sensations running through him.

Arielle swooped in as well, making out with her husband with more enthusiasm than she'd shown in years, her sex drive returning to and exceeding that of her younger self. Her tongue battled with Hank's, twisting around each other as Hank began to give in to the virus and sex. He knew his son-turned-dick daughter was the one with her lips wrapped around his bulging cockhead, but the way she flicked at his sensitive slit made it hard to care. He eagerly felt his wife's renewed and leaking breasts, kneading the swollen tissues and squirting milk into his palms. He experimentally licked at the fluid and immediately went back for more, sucking at his pregnant wife's teats.

Off to the side, Parker was fucking Rachel standing up, both eagerly watching their father as his control continued to slip.

"Yea, brother, fuck me like you promised. Fill me up again. I want it so bad," Rachel moaned as she bounced on his dick, arching her figure to get as much leverage as she could.

"That's because you're nothing but a pathetic cum SLUT!" Parker yelled as his cum rocketed out of his tip, filling his sister up again. She moaned at the glorious heat spreading inside her again, the sensation just as intense as the first time she had felt it.

At the same time, Hank groaned as Jessie hummed around his dick, his first load spilling out of him and into his slutty daughter's mouth. The girl swallowed it all eagerly, coaxing every bit out of his pulsing length. She finally pulled her mouth off and turned around, showing her dad her dripping wet snatch.

"Come on daddy, I know that's not all you've got. Why don't you teach your daughter a lesson for being such a whore?" Hank didn't even question how he was still hard, he just lined himself up and pushed into his daughter's virgin pussy, breaking her hymen like it wasn't even there. He rutted into her enthusiastically, speeding up as Jessie's tight cunt became accommodated to him.

"Oh fuck, it's so good!" Jessie screamed. "Fuck me deep, Daddy! Fill my fresh pussy with your seed. I want to be as pregnant as Mommy! Oh, right there, right THERE!!" she wailed as her first female orgasm overwhelmed her, her whole body going limp as she rode it out, cock spurting small bursts of her cum onto the sheets. Arielle was quick to swoop down and lick at the fluid.

"Mmm, baby, you taste so good. How about you put that cock to use and make another sibling for yourself?" she said, backing her own drooling cunt onto her daughter's throbbing shaft. The three bucked together, each one pushing at the others. Not wanting to be left out, Rachel and Parker came over and joined in, Parker shoving his third leg in his mother's slobbering mouth and Rachel circling around to lick and fondle her sister's sloppy pussy and father's balls, which were growing rapidly as the virus wreaked havoc on his body.

Titanic sacs the size of soccer balls churned with cum, the stimulation of his daughters quickly becoming too much. He grunted madly, any attempt at words lost in his frantic rutting, and his muscles tightened.

"Daddy, your cock is swelling up! Come on, you know what you want! Paint my cunny with all that jizz! Then I can cum in Mommy too and make another slut for you to fuck!! Give it to me! GIMME THAT CUM!!" Jessie wailed as her father grunted hard and his balls contracted, shooting a long stream of cum into his futanari daughter, already overflowing her cunt and dripping the excess onto Rachel's questing tongue.

Overwhelmed by the feeling of being cummed in, Jessie's orgasm hit too, her walls clamping down around her father as her dick spewed into her mother, who was already **** on Parker's potent seed. Arielle and Jessie's stomachs both swelled slightly, Arielle gaining another child to carry to term and Jessie's with the sheer volume of her father's cum, the thick fluid forcing its way into her womb and stretching it out. The women moaned at the feeling and their orgasms renewed, the entire family falling into a heap of sex and semen. They continued to fuck through the night, painting the room white with seed, mostly the product of the rejuvenated Hank and his colossal cum factories, only stopping when exhaustion claimed them.
