She's moaning and making all sorts of noise! It must be working! You knew it would. Your older step-sis loves to steal some of your candy on trick-or-treat night. This time you came prepared. She kicked you out and slammed her bedroom door in your face after you gave her the magic Boobie Blow gum that you bought online. You knew that would happen though too and you've been patiently waiting in your own bedroom, listening to your sis snap and pop her gum and giggling over the tingling sensation she's apparently having in her nipples. You slowly and quietly crack her door open so that you can see for yourself just how much progress the gum has made and....wow!!! Your sis's tits have swelled up like two huge balloons! How much gum did she stuff into her mouth!? Agh, thinking about your sis's mouth....seeing her now enormous tits....you are so hard in your pants as you continue to watch her! She seems to really be enjoying her new boob size. She can't stop touching, rubbing, and bouncing her inflated tits. You even overhear her saying that she wants more! More what? Gum? Cup size? Both apparently because now she's rushing across her bedroom to grab more Boobie Blow gum. Kayla must have figured out that every time she blows a bubble...her breasts grow! You know you should just take a picture with your phone and run back to your room to jerk off but you can't take your eyes off of her growing boobs. They just keep getting bigger and bigger. The same goes for your erection. Soon your bulge is straining against your pants, pressing against Kayla's bedroom door, and....creak! Oh no. She's spotted you spying on her! What happens now!?
