Bambi is pointing to what's basically a brunette version of herself -- well, maybe about 10 years older, and with breasts a couple of cup sizes bigger.
"Sure, she looks perfect!" exclaims the sex fairy.
The brunette notices the two of you and walks over in her high heels. "Hey, Bambi. Hey, Stud," she says, as if she's met the two of you many times before. She gives Bambi a friendly hug, but with you, she just puts a hand on your bare, muscular chest. "You know, I've never noticed just how much you're living up to your name."
You gulp, and the fairy whispers in your ear. "Ask her."
"Um..." You're staring into the brunette's cleavage, which is enclosed in a pink tank top. She seems to be staring down at your pants. "Um, would --"
She tears her gaze away to say, "You're looking good, too, Bambi! When are you gonna start working here?"
"Ha! I wish," says Bambi.
You hear a small voice say, "Granted!"
"No!" you exclaim, but that falls on deaf ears. Your already altered sister transforms further, her breasts growing even larger than the brunette's to strain against her sequined top, her hips and ass swelling to give her a more well-defined hourglass figure, her fingernails lengthening as her lips become noticeably plumper.
"Whoa, that's so cool!" says the brunette. "How'd you do that?"
"It's a sex fairy," replies Bambi as she cups her even larger breasts. "You should totally make a wish, Becky!"
"Okay, I wish my tits were totally bigger than yours again," says the brunette whose name you now know.
"Granted," says the fairy, still hovering near your ear. You watch as Becky's breasts swell, the tops of her areolae visible above the tank top. She looks extremely delighted.
"Doesn't that turn you on?" asks the fairy into your ear.
"I don't know -- that's about the 50th pair of boobs I've seen grow today," you point out.
"Okay, listen, I've had more than enough of your attitude," says the fairy, her voice taking a decidedly darker tone. "I didn't want to do this, but I'm going to make a little tweak to your brain."
"My attitude?" you protest. "You think my attitude's bad because I don't immediately want to have sex with every girl I see, and -- and --" You've suddenly lost your train of thought. You're now taking a good look at Becky, and, holy shit, does she look hot, especially with those massive tits she's got now. You just want to shove your cock between them, and --
"You okay?" asks a voice from behind you. You turn around to see Bambi. Her tits may not be as big as Becky's, but she's younger, and her lips look like they'd do a real good job of sucking you off. So what if she's your sister -- she's probably got a real tight pussy.
Hey, it's great that you're in this porn studio -- there's a giant bed right here in this fake bedroom.
"I'm better than okay, slut," you say to Bambi, and...
