so I was at this ski resort in Austria, visiting my then girlfriend (she was Austrian) and we went to a ski trip. She was in a very bad mood to a point where I decided not to go ski in the afternoon and stay at the hotel. I was on the balcony just drinking a coffee and reading a book and a woman, around forty years old went on the balcony just next to mine. She didn't aknowledge my presence. She was very sexy looking, in her underwear and with a guy shirt on. She went inside almost right away. I went inside a few minutes after to make myself some dinner and went back after to continue reading. She was there on the balcony (we were looking down on all the resort and shops and whatnot but we were pretty high) laying almost naked on the balcony (she still had the shirt on but it was open on her very nice and perfect size breast), she was smoking a cigarette very sexily, laying on her back on a towel. She had oiled up her body to tan (i'm guessing). She had sunglasses so I couldn't see her eyes but I thought she saw me. I took my book and started to read but I couldn't concentrate, I was just constantly looking at her smoking her cigarette. She started to touch herself, first pinching her nipples and then slowly rubbing her clit. I couldn't believe it. I was already hard but now It was hurting. It was apparent in my short and I saw that, although part of the fun was not to aknowledge what was happening, she had a very small smile, for a brief moment. I took my cock out and starting to jerk and she went very intense, breathing heavily. We were facing each others, masturbating outside, if someone had look our way the could've see something was going on. I was so horny, and I could see her fingers all wet from her pussy, she was almost dripping. She was breathing heavily and I stand up in front of her still jacking off like crazy, she had to put a and on her mouth to refrain from moaning too loudly and she came, I could see her body shivering for many seconds and I jizzed so hard, I wanted it to cross to her balcony and to fall on her but it didn't. I sat, coming back to my mind, It was like I was lost. I realized there was cum on the balcony so I went inside to get something to clean it and took a shower. I went back to the balcony after and she was still there, we never said anything. Shortly after my girlfriend came back.
