Fitting Room Fantasy

Being a 'girl of a certain kind', I always use the women's fitting rooms in stores when I am out trying and buying clothes. I tend to avoid the 'communal' type, where we are all stripping off together, as I'm quite shy and you also never know if someone may pick up on the fact that not everything about me is female - and make a complaint!
So I aim for those individual booths, where you can safely strip off and try things without being observed.

I was in one branch of a big national chain that sells a whole range of clothes within my budget and had gathered an armful of things to try on. There were a couple of summer dresses, some bright red skinny jeans, and a really skimpy bikini that I loved but which I had doubts would manage to contain my little extras!
It was quite busy and I noticed there was a line waiting to use the fitting rooms. Unperturbed, I joined the group of women and waited my turn. Soon others were behind me as we waited, the line was moving so slowly!

I felt a tap on my shoulder. A voice said "Excuse me, but I couldn't help noticing those jeans you have. I didn't see those on the racks, could you tell me whereabouts they are?"
I turned to face a gorgeous blonde, slightly shorter than me, with the prettiest face and a figure to die for.

"Oh, they were just over there by the entrance." I said, "You must have walked past them on your way in." She smiled, and I wondered if she had noticed that perhaps I wasn't quite all I appeared to be, but she certainly didn't show it, just saying "Oh, silly me, I must have, I guess I won't bother going to get them as I'll lose my place in this line"
"That's no problem", I said, "I'll hold your items if you like and keep your place for you while you get them."
"Oh would you? That's very kind!" She gave me another melting smile and held out her collection for me to hold while she hurried off.
I noticed that she had chosen some very nice things, including a slinky black bodycon dress that I really liked the look of.
