Its' your birthday and I'm trying to impress you and ask you out on a birthday date. My step-sister comes in with her breasts expanded to also try to ask you on a date! I get jealous so I decide to make my breasts grow for you too! We go back and forth making our boobs grow for you until finally, my step-sister gives up and transfers all of her breast growth to me! She leaves and accepts her defeat while I show off for you some more. We then masturbate together until we cum. *both characters shown in this video are played by me using video editing. There may be some bloopers throughout the clip
