Not one of your better pieces, I would say.

The idea in here, I like, I like where you went with most of it, even though I'm more of an ass man than a boob man. It was an interesting, very cut and dried explanation of the way suckling might be introduced to a relationship, possibly more realistic than any other I've read, which is admittedly, a small number. So great points on Vision.

I'm just not so interested in the characters. We know very little about either of them, beyond that Penny is 'unattractive,' presumably only because she's plump and has trouble with clothes sizing, and we know her boyfriend is rich and that he likes boobs on fat chicks. We don't even have the guy's NAME!

We get very little dialogue, and what we do get lacks signifiers, that would give hints to the emotions being felt while they deliver their lines, so their words seem flat. And there's never anything that clarifies who precisely is speaking, which may just be a personal problem, but I found myself having to count back lines and double check so I was sure who exactly was delivering some lines. The formatting messed with this, too.

We have information on Penny that we have no need for, like about her mother having died young due to weight-related issues, which would make one hell of an interesting story, by the way. I was excited when I read that, disappointed when it turned out to be irrelevant by the end of the story, except maybe where it says 'there was no health issue,' which medically, is unlikely, just to point out.

I had some issues with the formatting, too. The whole thing felt pretty 'wall-of-text,' if I'm being honest. Not as bad as a lot of what I've seen here, but definitely there. I personally double space between paragraphs to clear that up, it's just to help the aesthetic and how easy it is to find your place again, should you lose it. Someone on Dimensionsforums told me when I was first starting out with writing, 'Double space doubles the view count,' and I think you should try that.

And don't begin new paragraphs within quotes for a two, three word sentence. Only start a new paragraph within a quote if it will cover at LEAST an entire line and then some. It helps things stay clear for the reader, especially if there aren't any signifiers. I kept thinking the next line was a response from the unnamed boyfriend, where it was really just Penny finishing the thought she'd begun on the previous line.

It's actually a possibility my dislike of the formatting kept me from getting the full effect of some of the writing, but overall, I stand by what I said, not bad, but not your best.
