"You know, just because you look like a house cat doesn't mean you get to just laze around all day Aurora." The feral cat-girl and her passengers were woken the next morning by the scolding tone of her sister, the recently transformed latex cat-boy having left as they slept.
Aurora let out a prolonged yawn and stretched her six-legged body out before finally replying to her, "You know there's only so much I can do without opposable thumbs Camie."
"Bullshit, I've seen what you do to Nyataro with those tails of yours. Compared to that, wiping the floor should be nothing, isn't that right Jen?"
Jen was taken back at first at being directly talked to, but she guessed that it might have to do with the fact that she knew Camie personally before being fused with her younger sister.
"Yes it is Camie," said Jen, using the mouth on Aurora's breast. The feral cat-girl rolled her eyes at her bodymate taking her sister's side but got up regardless. Camie's statement proved more than true as her sister's quartet of cock-tails made quick work of the mess. As they worked however, the lingering scent of cum got the merged trio worked up and as they were just finishing up cleaning Aurora pounced on her kneeling sister.
"Come on Aurora," Sighed Camie. "This is what we got Nyataro fo-" her protests were cut off by Claire dropping a pill into her open mouth.
Camie's body began to simplify, her arms fused with her torso while her legs began a single mass of flesh. This continued until everything below her head except her breasts was a two-foot diameter tube, her clothing vanishing into nothing. Scales began to form along her entire body, bright pink and white along her back and sides while her front grew sky-blue scutes. The tapered tip of her serpentine body began to stretch across the floor, gaining foot after foot until it had more than quadrupled in length, a staggering twenty-five feet.
As her tail was growing, so were her breasts. Her tit, originally small B-cups, had grown beyond the practicality of cup sizes, each one a foot-and-a-half in diameter. Not only that, but two more equally big pairs grew in below them. All six of her breasts flopped onto the floor as they finished growing. Her vagina, which had transformed into a cloacal slit when her legs merged, opened up as twin horsecocks pushed out of it. Each shaft was two inches thick and a foot long, their urethras already drooling pre. Finally her face pushed out into a snake-like snout, her head becoming covered in the same scales as her body, while her shoulder-length(on her original body) long hair changed to pink with blue highlights.
"Are you sure you don't want my help? You look pretty pent up." Purred Aurora, her feral snake sister's cocks rubbing against her underside.
"No thanksss. We just finished cleaning. I'll relieve myssself in the bathroom."
"Alright then, enjoy yourself." Aurora rose to her six legs and slipped out of her room, the door knob having been replaced by a handle so that her feral form could manipulate it easily. Jen and Claire also noticed that Camie's transformation seemed to have caused every door in the house to now have a handle.
As the fused trio walked down the hallway, they heard moans coming from their patents room. Curious, Aurora pulled the handle down and peaked through. Inside they saw Aurora's father sprawled out naked on the bed with the pink latex cat-boy (whose name was Nyataro if what Camie had said earlier was any indication) eagerly deep throating his cock.
"I know we hired you to help with the girls libido, but I just can't resist your perfect mouth. Never imagined having our own live-in sex pet when me and Haily got married that's for sure!"
Any reply Nyataro might have had was lost into the cock streching out his rubbery esophagus. Since Nyataro was facing away from the door and her father has his eyes closed Aroura was able to easily slip in and stalk her way over to the bed. An outstretched claw held up to her mouth stopped Nyataro from alerting her father as she leaped onto the bed and dropped her rearmost crotch onto his face. As her father let out a muffled yelp of confusion, Jen and Claire both managed to slide a pill into his mouth. As they did that, Aurora used her forepaws to hold Nyataro's head to her father's crotch while her frontmost cock-tails slipped into his ass.
Aurora's father's muffled confusion switched to eager moans as his transformation began. He grabbed his daughter's two free cock-tails and began to stroke them as his hands became dainty and feminine. Fleshy webbing formed between each of his fingers, the wedding ring he wore becoming a bracelet, as their nails lengthed and were covered in a layer of turquoise paint.
He began to attempt to eat out Jen and Claire's mouth pussies, awkwardly alternating between the two of them. As he did the sisters felt his lips plump up as his entire face feminized, the pitch of his moans rising. From the eyes on Aurora's breasts they saw his legs fuse together into an iridescent, rainbow-scaled mermaid tail. Their rear torso was then lifted up slightly by two pairs of breasts.
With their rear eyes the sisters then saw as his face was stretched horizontally, spliting into two identical heads that each began eating/making out with one of their pussy mouths. The final change happened up front, where Nyataro slowly transitioned from sucking on a cock to eating out the center of three pussies. As Aurora's father's transformation came to its conclusion the everyone came in sequence, both Nyataro and both of Aurora's cocks not inside the cat-boy covering the—now waterproof—sheets of the bed.
"You know you don’t need to sneak up on me like that Aurora." "I'm more than willing to help satisfy your friends" The mermaid spoke the first sentence with one head, and the second with the other.
"I know Daddy, but you seemed to be really into Dad eating you out, so I didn't want to distract you."
Any further discussion was interrupted by a call for breakfast from Aurora's mother, everyone heading out to eat.
"How are my two hubbys doing today?" Greeted Aurora's mother, Haily. The only remaining human in the house gave both feminine men a hug and a kiss. The latest shift in reality had made Nyataro go from a live-in sex worker to Aurora's second (and biological) father with Aurora being born with her mother while Camie was the child of Nyataro and her mermaid father. As the five (seven counting Aurora's bodymates) of them sat down for dinner, Jen and Claire pondered how they might get a pill into Haily's mouth. A perfect opportunity at last arrived as Aurora stood up on the counter to place her cat dish in the sink. Haily was scrubbing her own plate at the same time and Jen hastily spat a pill into her mouth. She was in such a rush that she accidentally bit the pill in half, the other part dissolving in her mouth. Thus when Aurora affectionately brushed her rear torso against her mother's legs, they began to fuse together.
The mass of Haily's legs and hips immediately went to making her daughter slightly taller, from two-and-a-half feet at the shoulder to three, leaving her upper body attached to the feral cat-girl's rearmost hips. The fur on those hips then began to fall away, revealing pristine scales the same shade of green beneath them. The feet of these legs morphed slightly, growing into draconic talons with wicked claws. Just before reaching their middle hips the scales finished replacing the fur, leaving a smooth transition between them. The two cock-tails went from thin, feline appendages to thick, tapered, reptilian tails. The cocks on each one doubled in length to sixteen inches but retained their feline barbs.
Meanwhile, the green scales had begun to spread up Haily's upper body as well, with a lighter shade on her belly than on her back and sides. Once the scales reached her arms her fingers elongated massively. Thin webbing connected them both to each other as well as to her sides, like the wingarms of a bat. Finally her face pushed out into a muzzle, six-inch long incisors hanging from her maw and her short-cut black hair became an ebony mane parted by a quartet of twisting, ivory horns.
"Here you four, let me do the dishes." Nyataro, now the only remaining member of the household with both hands and legs, stepped up beside the quartet and started scrubbing.
"Thanks dear." "Thanks Dad." ""Thanks Nyataro"" Both mother, daughter and bodymates all thanked him as they walked over to their other husband/father/lover, Camie having excused herself and gone to her room a moment ago. Haily, who seemed to be in control of just her upper body and the draconic cock-tails, slipped them over to the mermaid and teased them over his outer two pussies.
"You know honey, now that both our girls are all grown up, I was thinking we could have some more kids, I never did get to put a bun in one of your ovens."
"That sounds lovely." "Maybe you could do all three?" "Nyataro did get to sire both of our kids last time." "So it would only be fair if you got the next batch."
"I'm still in the room you know, not that I have any objections. Just as long as I get to participate in all the fun that involves." The latex catboy wiggled his butt as he spoke, his latex cheeks squeaking as they rubbed together.
"You know that Jen, Clare and I always up for some fun with you." Added Aurora, her own cock-tails lifting up in anticipation.
