LITTLE STEP-SISTER'S BUST EXPANSION

Little Codi has her eyes on her cute, new step-brother. He thinks she's too little for him, but she's going to prove otherwise. She knows he likes girls with big tits, and she has a potion that's going to make hers huge. She takes a sip and feel her chest fill up right before his eyes. Then she gulps down the whole cup and starts busting her bra. "You like me, don't you?" she says. "You like me now that my tits are getting bigger. Come on! I promise I won't tell anybody, and I'm not a little girl anymore!"
