This story is all true!
Near my hometown there is a city where a lot of houses are abandoned, including some bunkers, a big hotel and a big former train station! Since I love exploring old abandoned places like that and love getting nude and jerk off in such places I definitely had to visit this building too! Since its near a rather big road I had to be very careful not to be seen getting in!
One warm summer day, I took the chance of an empty street and went into the building through an old pedestrian tunnel! And what I found in this building was worth all the risk! A big train station with most of its furniture (even the documents, chairs, the coffee machines...) still inside! As I was searching through the house I found the locker rooms, and in every second locker I found some porn posters or pin ups, which immediately made me curious to find more and my cock grow hard!
Since it was summer I was only wearing shorts and a t-shirt which is quite handy for getting undressed and dressed fast! Walking around through the locker with a hard on and my hand in my pants made me so horny that I decided to go nude, since nobody could see me from outside and I guessed that no other person would be here at the same time! So I got totally naked and put my clothes into one of the lockers and only took my cellphone and keys with me!
And just like that, totally nude and jerking my 7 inch hardon I continued my trip through the building, walking through the main hall, some old shops, some other rooms, upstairs to the buffet, the kitchen and then into the old offices, occasionally take some pictures, and in one of the offices I hit the jackpot! a table fully loaded with 80s and 90s erotic and porn! Since it was spread all over the table, even with some cum stains on some pics, I guess someone already found this! Since I had a hard on since about half an hour I decided to finish playing! I quickly took some pics for the archive and then went on jacking for the grand finale!
So I stood there completely naked in an abandoned office looking at a table full of porn, with my clothes about 300 meters and 2 floors away, jerking my cock it didn't take long to finally cum!
I shot an immense load all over the porn on the table and it was one of my best orgasms ever!
I just wanted to take a picture of my 'mess' when I suddenly saw a couple (both about 30 years old) standing at the door clapping their hands!
I was just shocked, standing there naked with cum everywhere and no way to hide or to get my clothes!
But they just stood there and told me that its ok, and that they used to have sex around this old building, and that they have seen the older cum stains before and have seen me walk in and got curious if I was the reason for the stains! I told them that this was my first time in here but definitely not the last time! They just said that the show was much better than they had expected! I could see that she was quite horny and that he had a huge tent in his pants, and since I was still standing there naked talking to strangers I got hard again too!
Unfortunately they didn't want to give me a show, but after telling them that they had seen me naked and jerking it would only be fair!
After some discussion the girl pulled her summer dress up and revealed some very sexy lingerie panties and really hot braless boobs, and touched her goods gently, which made me so hard again!
I could see that her boyfriend was also hard as hell and started jerking in his shorts!
Before she slid down her dress he pulled his pants down and started stroking! Then she grabbed his cock, stroked about 5 times and he came all over the porn too, while I was just standing there watching, stroking my dick! Not long and I came a second time!
After that we walked back to the lockers together where I put my clothes back on and wanted to leave when the girl gave me a cellphone number and said that I should text when I'm visiting again!
So far I didn't have the chance to go back and call, but I certainly will!
