Girl in Dress Distress

So a friend here just asked what my fantasy for today is...

While out shopping I found a cute dress, a size too small... and too short, but...
it was a back-zip mini-dress at Macy's. I squirmed into it and it was so cute, but my diet isn't going well... So trying to take it off, the zip stuck. Exasperated and embarassed, I found a clerk and asked her to help me with it. People were staring. I must have looked silly, half in and out of that skimpy sale-table sundress. She sent a manager-intern, 26 yr old total hunk who took his time freeing the zipper with warm gentle hands. And when he got it loose, he zipped it up tighter and then so slowly began pulling it down. It was a long zipper and eventually it was at bottom, and he could see my underwear. And the dress was loose enough that the shoulder straps fell down on my arms. My bra barely held me and it was on its own. His warm hands were at my waist, and then he was tracing the waistband of my panty. I gasped, covering my mouth with one hand. I had no resistance when he began to pull the dress over my head. He hung it over the door, then turned me to face him and picked me up by my bare thighs. I felt off balance and instinctively threw my arms around his neck.
