The choice was a hard one, but nothing was going to beat the classic cat-girl, black fur for him, white for his sister, combined with matching hair.
Their faces should look innocent and cute, their locks lush and beautiful, falling to the floor. Pale skin that had no blemishes, hands that are dainty and a body that looked like it would struggle with any strenuous task, but still could bench-press a car, that he desired
However, that did not mean that he could not add some other, lewd ideas. Added breast rows for example, with plumb, sensitive nipples, which would be perfect to play with and to suckle on, extra sensitive ears that made them cum if pet hard enough.
He did not touch the relationship options of his sister, but he still he changed their ages to match the new world he created: Ten for him, fourteen for her. “I hope we’re going at each other.” he said to himself.
With everything set up, he finally pressed the button to save the changes and everything went white.

The first thing she felt was her burning loins and instinct guided her hands. One went to the twitchy hole between her legs, childish moans coming from her mouth as it made contact to her needy folds, coating itself in her juices. Another glid to one of many throbbing points of her front, tweaking with her aching nipple. Her breaths turned sharp as she felt a sexual warmth swelling inside her, each movement an act moving her to the high point of her arc.
Her head fell forward onto pillow. She whimpered loudly into its depths until orgasm came over herself; fingers twitching against themselves frantically before flicking away wildly towards anything available within reach. It took Jay several seconds to breathe normally again. Her mind was clearer now, as the lust went from immense to only high. Thoughts swam through her brain rapidly about what she did.
Her dearest wishes came true! She became a horny catgirl loli! She brought a long, black stripe of her hair to her face. It felt wonderful! A purr escaped past her mouth. And her tits looked giant on her child body. They were perfectly round globes topped off by nicely shaped nips protruding proudly, all eight of them. This must be how boobs feel. only better since these things don't get sore nor saggy, made better by her chronoviac. Only downside she could see at the moment is that a part of her view is blocked by her eight tits.
She could not see her pussy, but she felt it ache, begging her to finger herself again.
She giggled, shocking herself with the sound. "Even my giggles sound cute!".
As she got up and stretched, her tits jiggled and wobbled with each movement, turning herself even more on.
She walked to the mirror and gave her body a look over. No acne, no fat and her body was slender in sexy way. Her tail and ears were as they should be and made her even cuter! The perfect body for a loli catgirl. Under her tits was her small, hairless vagina, adorned with her slit. A drop of juice fell from it on her legs, and judging by the trail of stains going from her bed ending in a huge mess of wetness on it, not the first one. She rubbed her thighs together at the thought of all that being her pussy juice, her tail swaying from side to side.
She walked to the floor, not even giving a thought to her nakedness. When she walked by her big sis' room, she heard loud moans coming from inside, eliciting a deep breath from Jay. She opened the door slowly and peeked inside. There was Jen, kneeing on her bed and supporting herself with one arm, while the other fucked her pussy furiously, femcum overflowing her lips. White hair framed her teen body , accentuated by white ears and a tail. The little catgirl caught movement and her eyes fell upon Jen's torso. Huge, heavy breasts strained the shirt she wore, a wall of titflesh hanging freely without support. Her nipples stood out from under the textile, forming big tents on the surface. Hotness in its purest form.
"You're such a slut now," whispered Jay under her breath "like me".
Jen let out a muffled moan as she masturbated, not noticing her little visitor. Soon her hips bucked and her pussy errupted, gushing cum everywhere, some even landing on the little child's face. She fell down her bed and recovered from her pleasure, seeing her onlooker as soon as she did.
"Oh!" she exclaimed. "Sorry, I did not see you, little squirter. Else I would have asked you to join in."
Jay smiled, wiping the girlcum still dripping from from her face and said the first thing that came to her mind. "You know I love watching your bunch o' boobs bounce around when you fuck yourself silly, big sis."
Jen smiled cockily. "Well, if you want more fun, you should come here too, little squirter! I'll make sure you won't regret it."
Jay nodded eagerly and walked to her sister's bed.
The girl on the bed buttoned up her shirt and threw it asiede, revealing her huge mounds in all their glory. They looked exactly like her little sister's did, except even bigger.
The first thing Jen did was bringing her hand on Jay's head, who let out a mewl in suprise, before panting as her big sister petted herfuriosly, building up a heat inside, before it errupted quickly in overwhelming climax, staing Jens body in her little sister's cum.
That was just the beginning and it wasn't much longer until both girls found themselves on top of the other, kissing passionately and rubbing their bodies together, their hands roaming every inch of flesh, exploring every crevice and bump. Their rows of boobs grinded together as the smell of sex hung heavily in the air. Both girls were moaning loudly into each others mouths, their tongues deed inside each other, and fingering each others pussies. Digits slid in and out, in and out, faster and faster, making the sisters scream and jerk uncontrollably. Sweat started forming on their bodies as it continued on and on, making everything slippy. Cum dripped down from their cunts, mixing with sweat and running down their thighs,turning the bed to a lost cause of wet sheets.
The sisters fucked like this for quite some time, until finally Jen broke it up.
The younger sibling sat there for a second, panting hard.
Jen broke the silent pleasure cooldown. "That was fun little squirter, but now we need make ourselves ready for school, we are already behind schedule."
"Damn, I forgot about school!" cursed Jay inwards.
Both siblings quickly dressed themselves, which for Jay meant her simple, blue-and-white blouse, her short skirt, not even hiding pussy or ass, white stockings and black mary janes. She noticed a lack of underwear in her garderobe and made a note to herself to see if that concept still existed.
They grabbed their schoolbags as well, hers decorated with a cow girl spraying her milk, before heading outside.
As the door shut behind them, Jay grinned widely, already thinking of what school would look like. It was gonna be great, she was sure!
