I wrote two stories for this comp. The first one, I didn't read all the rules (do'h!) and didn't include anything about flashing in it. So I took it out of the comp about 5 minutes after entering. It's got bondage, filthy phone calls, potential threesomes, and two full hours of edging. It's called Gift-rapt. I'm really proud of this one. I like to think it packs a little heat.

The second story IS my official comp entry. It's lighter, less emphasis on sexual heat and more on dialogue (it's the same unnamed couple as the first story, and most of my other stories). It gets very nipple-centric, if you are into that kind of thing. Clearly, I am. 
With a little exhibitionism thrown in, just for kicks. Chris M called it "elegant." The story is Faith and Joy.
