You used to make fun of my small chest, brother...but now look! My boobs have grown ridiculously and now who will insult who? Now you can't stop looking at your own sister's tits...may be I'll put on a show just for you. Pouring water over my body, my shirt clings to my skin. You can see my cute pink nipples! My boobs have grown so much. Come on brother, don't be embarrassed. What's up, you don't like your big sister?
