I come home from school today and confess to step-mom... they were making fun of me again for not having any boobies! But step-mom says not to worry... she has the solution! She found out that sucking off my step-brother and swallowing his cum enhances the estrogen in our bodies to make our boobies grow super big! Hers have been so big ever since she discovered this neat trick and she decided to let me in on the secret because she never wants me to be teased ever again! But I get a little greedy and decide to make a deal with my step-brother that if he gives it all to me and not her then I'll do all his homework forever and ever! Lo and behold my boobies got SO BIG and beautiful and bouncy!! But then step-mom walks in and we get into a fight only to realize what the principle behind this whole situation is! There's a step-son to be learned in everything.
