I couldn't believe my luck. I was sure that at any minute she'd remember the window and pull the curtains, but instead she stood there, displaying her tight little ass to anyone who might happen to look in the window. I almost fell off the bed as she then slowly and deliberately leant forward, exposing her ass and pussy to me. She did this a couple of times as she picked things up from the floor.
I was mesmerised, and by now my thick cock was completely hard and had pushed aside my towel. For a moment I wondered if I was just as exposed as she was, but then I remembered the difference - her light was on and mine wasn't. With that I started stroking up and down my shaft as my eyes remained glued to the scene across the alley.
She turned, completely naked and in full view of the window, and for the first time I saw her breasts unhindered by the costume. They were petite and pert, with gorgeous little nipples that looked like they were hard as rocks! God I'd have loved to take one in my mouth and roll it between my tongue and lip. As my eyes wandered down her incredible body I noticed that she was completely shaved. I almost thought I could see a slight glisten on her pink little pussy lips.
What was motivating her to expose herself like this? There was something about the way that she was behaving that suggested a nervousness. Was someone telling her to do this? Had she lost a dare? Yet she seemed wet - was she enjoying this? Where had she been all dressed up but completely nude under her costume? Who else had been enjoying the movement of her tight ass and breasts as she moved around in it? My mind was racing and I could feel myself getting closer to coming.
Without pulling the curtains she turned again and lay on the bed. She crossed her legs and I saw her hand dip between her legs. No fucking way. This goddess was actually touching herself in front of a completely open window in one of the busiest cities in Europe.
My hand worked furiously as I watched her masturbate. I could tell she was getting close to orgasm as her breathing sped up and her back arched. Just as she reached her climax I couldn't take it any more and I came as well, thick ropes of come spurting across my flat stomach and running down between my balls and my thigh. Incredible.
I lay on my side as she switched off the light. It was one of the hottest experiences I've ever had.
