Are you looking for most recent wank in private... or does a little audience count?
This morning. Opened the curtains in the hotel room. Still somewhat dark outside. I noticed a couple of people in offices in the building across the street. I turned on a light in the hotel room and stood in front of the floor to ceiling window naked. I started playing with my dick and balls, light touching my nipples.
When I was semi hard I noticed that I had caught the attention of a woman. She massaged her tits a little through her blouse. I then noticed a guy in an office on the floor below her. He got up from his desk and I thought he was leaving. However he shut his office door and walked over to the window of his office. He started playing with his crotch. The woman above, full figured and in a skirt and blouse, was still playing with her tits and was now blowing kisses. My dick was now rock hard. The guy below her pulled his dick out of the fly of his trousers. He was nice looking, mid 30s from what I could see. I milked a glob of precum out of my hard dick and tasted it, looking at them both. She blew another kiss. He reached into his fly and pulled out his balls. He now had a full hardon and the dude had an impressive boner.
I stood in front of the window, looking at both of them, stroking my dick, playing with my balls, touching my nipples, tasting more precum. I shot 5-6 heavy squirts of cum onto the window. She blew me a final kiss; he shot a load into his hand.
We smiled and nodded. I walked away from the window and to the bathroom to shower... my still hard dick bouncing in front of me.
Two hours later, as I stepped onto the aircraft for my first flight of the day, I realized I forgot to clean my jizz off of the hotel window.
