Your little step-sis Codi wakes you up to show you a cool rock she found. It looks smooth and purple and feels magical! She brings you into the bathroom to analyze it and it starts to have an effect on her! Suddenly she feels tingly and her breasts begin to swell up. Soon she unbuttons her top to reveal two huge melons growing under her small bra. She then shoots up about a foot taller! Now your not-so-little sister looks like a tall busy goddess. She confesses that she's always wanted to be a bigger girl like the ones you touch yourself to... She asks you to inspect her new breasts and asks you to hold and touch them. Apparently it gets her really horny because she starts to strip down and sit on the bathroom countertop, gently and shyly asking you to show her your cock and fuck her hard! After you both cum, she can still feel her breasts expanding and she marvels at how big they will be at the end of the summer and how she'll be the only thing people talk about when she goes back to school!
