I show up for a lingerie modeling gig to find out that my rival is there too! She always teases me for having smaller boobs than her and I hate it! In the dressing room she gets up to her old habits, but this time something changes. I can feel my breasts starting to grow... and hers shrink?? Before long I'm too big for my bra so I take hers and she runs off in shame. I'm left to explain to the director what happened and with a craving to try out my new huge tits...
