The Overflowing Bra

You sir, have failed at the English language. Improve your writing skills and edit your story before you churn out another one. Take this story back to the drawing board. It has potential, but it needs to be completely reworked in order for it to be readable. The dialogue was atrocious and poorly thought out. Grammar, and such were already commented upon thoroughly by the others. Heed the advice given to you, and rewrite this story.

Great start to a story. Loved it. But it is hard to really get a grasp on how big her breasts were before and how big they were afterward. usually bra sizes or comparing to everyday sphereical objects can help a ton. and there are just a fewwwww grammar errors that a quick proof read could fix up. but overall great job, keep on writing

Not a bad start.  Don't forget the GTS tag! 

Good

Underwritten:  too little description, no real sense of the characters, and any background exists just to give them a reason for getting to the sex.  Any details are kept in the author's head.  
Your basic one-shot fantasy saved as a file.  This may excite the author, but there's been more than enough held back to make his experience a potentially isolated one.  The writer spent lots of time watching the action and very little on telling us what he was seeing.
