She picked her cousing Samantha, her father's little sister's girl. Tina never understood why Sam looked so bony-assed. They had pics in the old photo albums of Aunt Kay at eighteen when they brought her along to Hawaii. Aunt Kay was freaking hawt in a bikini at that age.
She must have been a cock-tease, too, because although most of the pics were of her and Mom with toddler Tina and Jeff the three-month-old baby, there were a couple with Dad between Mom and Aunt Kay with his arm around each. Kay was pressing her gazongas into Dad's side, pretty obviously trying to get him aroused.
Sam had come along at the same time as Tina, but she had no baby-daddy, so it was just her and Aunt Kay. And in any kind of a just world, Sam would have inherited at least something from those oversized tits. She shouldn't have been scrawny and flat, and a bookworm nerd who did nothing but hide at home and watch anime when she wasn't reading.
Tina picked her, and to her surprise, a very life-life pic of Sam appeared, not wearing a stitch of clothing. She looked awful.
Well, not awful. Without her glasses at least her face was kinda cute. But from the neck down she looked like a half-starved boy with no dick.
Playing around with the tools, Tina was able to find out pretty quick what Sam would look like if she ate properly. It still wasn't anything special. Her hips had a little curve now, but she was still flat. So Tina gave her slightly bigger tits.
It was okay, but not really was she was gunning for. After a bit of playing around, she discovered how to get Aunt Kay up on the screen also, for reference. But Aunt Kay at 37 was not the hawtie from the photo album. She adjusted her age downward until the two were the same age and at last those glorious things were there to compare with.
Or to copy & paste, which she quickly discovered she could do. But with Sam still carrying less weight (her ribs were still visible), the DDD cups now on her chest looked fucking amazing.
She got to thinking about Sam's thing for anime, and tried to put cat ears on her. The computer had to ask a shitload of questions first, but she was able eventually to convince it to give her an orange tabby haired cat-girl version of big breasted Sam. For the fun of it, she gave Aunt Kay the gray tabby treatment. they both had tails and ears, and the ears were real functioning ones that replaced their normal ones. She'd had to agree to let animal-girl 'living accessories' be a popular elective surgury. They each had super light fur in their pubic areas too, matching their hairdos but like short-haired cat fur instead of human pussy hair.
They looked fucking awesome. She had to save this. She searched and found a function that looked like it would do it, but when she clicked it, the screen said "Subject Kay Blank no longer fits role as mother to subject Samantha Blank. Role adjusted to 'twin sister', maternal role assigned to now deceased substitute 'Kelly Blank'."
Why was this dumb game generating useless trivia like that? She wondered, but then blinked as something flashed briefly, just outside her vision. She felt a little strange for a moment.
Then she shrugged and hunted around for what she could do with the pair on the screen. She discovered 'live test mode' and giggled at some of the choices it had. She could test the 'subjects' having sex? She decided she had to try that.
It wanted partners for them. With a laugh, she decided to have them screw each other. The computer made her adjust them to bisexual and lacking incest inhibitions, and then she watched with a giggle as the screen quickly showed them in super fast forward until they climbed into the master bedroom bed at Aunt Kays house. Then her jaw dropped as a porn-movie quality lesbian scene of two live-action cat girls started playing in front of her. She zoomed in from 'Sims' level until the bed filled the computer screen.
Tina wanted to call Sam and tease her somehow about this. She wasn't sure what she was going to say when she dialed Sam's cell number, but her jaw dropped again when she watched Sam reach out, search around for her purse, dig out her cell and answer it on the screen, while Aunt Kay was down between her legs, eating her out!
"Hey, Tina," she heard Sam say on the phone. It was coordinated with the picture, and sounded like she was struggling to control her breathing!
"Uh...." Tina searched her mind for something to say. "Hey, Sam. Watcha doin?"
"Oh... just... uh, watching anime."
She heard an intake of breath as Aunt Kay reached up and gave Sam's tit a hard squeeze.
"Oh yeah? Which one?"
"N... nothing you'd have heard of," Sam gasped. It really was the same as the screen! What the fuck?
"Hmmm. From the sounds of it, I bet you're watching one of those... what'd'ya call em? Hentai things that you like?"
"Oh fuck off," Sam answered, annoyed.
"No, I definitely hear breathing. Like you're fingering yourself or something. You didn't bother stopping when I called?"
"Whatever," Sam grumped. "Bye".
Tina watched in amazement as the girl on the screen hung up at the same time Sam cut the call off. Then the girl arched her back and raised her butt off the mattress. She was cumming!
The girl dropped back onto the mattress at last, breathing hard and covered in sweat. Tina picked up her cell and texted, 'I bet you just came, didn't you?"
She stared as the girl on the screen looked at her cell, pooched her lips, and texted a reply.
A reply came in on Tina's phone just a moment later. It said. "Fuck off." It included a close up pic of Sam sticking out her tongue at the cell phone camera.
Sam with orange tabby hair and ears!!
She watched on the screen while the gray tabby crawled up on the orange tabby and then reversed so they could 69. Her tail was waving back and forth in the air as she began eating Sam out, exactly like a real cat.
"Is this for fucking real?" Tina breathed. Still unable to quite believe it, she decided to try something else to test it. She would put someone else there banging the two of them, and then call that person! She decided to use...
