Tried to get into my stall

As I was changing I heard a rapping at my door. Standing there half naked and confused I called out, "Becky?"

"Yeeeeeaaaaah?" She tipsily responded.

"There are other stalls, you know."

"But I need your heeeeeeeeeeelp."

I sighed to myself and weighed my options, I slowly opened the door to tell her she didn't need to get undressed when she simply barged through with a simple thank you.

We were now in a very cramped space, with her body only a few inches from mine. Before I could get in another word she reached her arms behind her back and, quite impressively, unzipped her dress all the way down, she then brought her arms down and let it simply sink to the floor.

I stood in surprise as I then realised she had forgotten to where both panties, and a bra, and was now completely naked not counting her high heels.

She then looked to me cheekily. "Does this work?" She asked before winking as she noticed me taking in the view of her.

At this point she was able to completely top all her prior actions, by leaning into me and resting her hands on the wall behind me. I was now, for the most part, trapped. Stuck with only a shirt and bra on, while a naked Bethany continued closer as I tried my best to lean away without touching the toilet.
