After you deleted your dad, you decided that just having your mom and Megan to play with was a little limiting, so you pulled up a tab to add some new sisters to the family.
You use a cartoon about a guy with lots of sisters as vague inspiration. You’ve never real watched the show, but you’ve read a ton of fanfic’s with the guy at the center of an Incestuous Harem.
You start with the second youngest, skipping the baby in place of Magen, aging her up a bit
Name: Mona Airs
Gender: Female
Age: 9
Height: 4’7”
Weight: 96lbs
Hair: brown
Eyes: green
Breasts: C cup
Main Trait: Genus level IQ (Collage student at age 9), Mad Scientist
You hit enter and you can feel reality shift, your house is a little larger and you can now see “Mona” on screen in her room/lab. Your mom’s breasts are back up to F cup, likely from making Mona’s chest so large
You move onto your next new siblings, the twins.
Name: Myla & Myra Airs
Gender: Female
Age: 11
Height: 5’0”
Weight: 118lbs
Hair: blond
Eyes: blue
Breasts: D cup
Main Trait: Opposite personality twins, Girly Girl (Myla), Tom Boy (Myra)
There was another shift, but not as drastic this time. Megan stuff has been moved into Mona’s room and it seems the twins have moved into Megan’s old room. Looking around you find the twins fighting in the TV room over the remote, they aren’t quite what you imagined them to be.
Moving on
Name: Moon Airs
Gender: Female
Age: 13
Height: 5’4”
Weight: 144lbs
Hair: blond (dyed black)
Eyes: blue-gray
Breasts: F cup
Main Trait: Gothic loli, loves vampires and zombies
The house had another new bedroom after the shift and moms chest jumped to H cups. Moon was in her room in a super frilly Goth dress, lying on her bed and writing in what I presume is her diary.
That was the last of my little sisters, time to work on the older ones
Name: Macy Airs
Gender: Female
Age: 18
Height: 6’6”
Weight: 251lbs
Hair: brown
Eyes: brown
Breasts: GG cup
Main Trait: Star Athlete, Female Body-builder
After the shift I found my new older sister downstairs in the now greatly expanded version of my little workout room, by god she is jacked, she has to be two-hundred pounds of pure mussels, no wonder her weight shot up when you added the female body-builder trait. You also noticed mom’s age went up, likely to reflect her having an 18 year old kid. She still looks the same, she seems to have the “Look’s 20” Trait.
Next
Name: Maud Airs
Gender: Female
Age: 19
Height: 6’7”
Weight: 188lbs
Hair: brown
Eyes: brown
Breasts: K cup
Main Trait: Fun-loving Goofball, A Little Crazy
You didn’t find Maud in the house, but you did find evidence she lived here, guess you shouldn’t expect all your new older sisters would be hanging at home after school instead of with friends or something, you’ll meet her later. You haven’t said it yet, but every time you add a new sister, you get ghost memories of growing up with them, IYRC Maud’s BFF is having a birthday today, you have a ghost memory of her saying so this morning at breakfast.
In other news, mom has hit MAX LEVEL in the breast department at N cups; you got a warning that the game can’t enlarge them any further without putting mom’s spine at risk.
Three more sisters to go
Name: Mika Airs
Gender: Female
Age: 20
Height: 6’8”
Weight: 222lbs
Hair: brown
Eyes: brown
Breasts: KK cups
Main Traits: Rock star (Garage Band), Basement Dweller
Quick look reviled Mika napping in the basement; she seems to share the room with Macy.
Name: Mary Airs
Gender: Female
Age: 21
Height: 5’9”
Weight: 163lbs
Hair: blond
Eyes: blue-green
Breasts: J cup
Main Trait: Bimbo Slut, Brothers Sex Slave
This one you’re planning to have fun with, you’ve always had a thing for Incest, and from the start you were planning to build a harem for yourself, including your mom and Megan, but you’re planning on making a game of it. You’re only giving yourself Mary as a free-bee.
Last one
Name: Mina Airs
Gender: Female
Age: 22
Height: 5’11”
Weight: 175lbs
Hair: blond
Eyes: green
Breasts: LL cup
Main Traits: Engaged, Pregnant (Daughter)
This one is hard mode, you didn’t set her fiancé yourself, and Ghost memories say it’s some guy named Bill, but you’re planning to seduce your own sister into leaving him and tacking his own daughter away from him. You’ll likely add the kid to the harem too, when she’s older.
There, cast set. But that’s not the end of it. You’re planning to make a few more changes
