Yah dirty Beast! Lol, I totally get this though. I remember two incidents when I was at college. The first was one evening my girlfriends housemates were smoking in the backyard and saw the guy who lived in the house behind wanking in his upstairs window. They thought he'd forgotten to close the blinds. But, unknown to them when I stayed over I'd often gone into the backyard at night when my gf and the rest of the house was asleep and wanked bollock naked in the yard (Seemed a bit wrong to try humping the girlfriend when she was asleep, at least that's my excuse for some exhibitionism.). Anyway our yard would have been visible from this guy's window and I suspected he'd seen me at it sometime and been inspired to do a spot of "Danger wanking" himself. 

The other time I'd gone to stay with a mate. He was in a house share with three crazy girls and one day he told me he had really bad blue balls because he couldn't wank in the house he shared with girls "It wouldn't be right". I told him to get over himself and anyway I'd enjoyed a wank in their bathroom that morning sat on the really broad windowcill with the sun pouring in. He was appalled and reckoned that everyone would have been able to see because the window privacy frosting wasn't really effective. I said I hadn't thought of that (But I'd spotted right away that the glazing didn't really hide anything, which was basically why I'd done it). He worried that people would have seen and thought it was him because we looked similar and I was like, yeah tough shit you've gained nowt by not beating off!

love stroking in front of the open hotel windows

I used to jack off at my windows when I was in college from 1973-1977 in College Station TX. It was amazing how many people saw me and how many people knocked on my door asking if they could jack off with me.

I came to San Diego CA in 1993 and have enjoyed jacking off outside, especially if there's the possibility of someone seeing me and choosing to participate. The pictures following are of me jacking off on the bluffs at Blacks Beach in San Diego and a young man seeing me and helping me, and then letting me help him.

Picture 2, him helping me.

Picture 3, me helping him.

I love this sort of fantasy, love the idea of being seen and then someone wanting to join, or catching someone and being invited to join. 

I have certainly risked it in hotels before, love the idea of being caught! 

A few decades ago I was staying at a hotel in Reno, Nevada. I ordered room service food, and the most adorable guy brought it. I asked him if he wanted to spend some time letting me massage his dick and balls. He said yes, but that he didn't get off work until 10pm. I told him to come back by. He did! I was hoping he would, so I was naked and jacking off. When a knock came at my door, I simply yelled, "Come in!" He saw me and immediately got naked. I jacked him off for a couple of hours, not knowing that I was edging him because that was not a term yet. He shot his load over his head an onto the hotel well. I asked him if his job required him to clean his cum off the wall. He laughed.

@doubler Lucky man! Who took the photos?

Camera on a tripod set to take a picture every 5 seconds.

I have actually done some Masturbation in front of my hotel window, with a hotel right across the street! I had a small bed side light on and it was about 10 pm. I had all of the curtains open, and anyone could clearly see in to my window! I was so very excited and Horny , that I put on a sexy red lace bikini panties and had a porn video on my laptop. Which was facing the window so that I could watch! As I was standing in front of the window, I was getting very hard and I could see several people in different rooms! This really turned me on, knowing that I most likely was being watched! At this point, I really didn’t care who would catch me stroking myself! I just sat down in a chair, facing the window, with my feet up against the window and slowly started stroking myself! It wasn’t long, before what I was doing, caught several different people’s attention! A older woman, was watching me and she walked away, and then came back with just a lace panties on and no bra. I pretended not to see her at 1st, as my cock was getting Harder! As I was watching her, she pulled out a glow in the dark Vibrator and started sliding it between her legs! And also she was sucking on her really big tits and nipples! I could tell that she was a full figured lady! 
at this point, movement caught my eye and as I was looking one floor above me, I could see a naked guy standing there and he actually waved at me as he was stroking himself! Anyway, it turned out that the lady, gave herself a nice Orgasm and the guy ended up shooting a nice big load of Cum on the window! Watching all of this gave me an amazing Explosion of Cum!
