Yes, once in a very very crowded train journey, in my city, this guy (probably in his mid 40's) came and stood in front of me with a medium sized hand bag which kept hidden his dick (luckily i got a seat as i boarded from the source station). And I wuz bloody horrified when I saw his dick dangling in front of my face. It wuz probably 9" long and quite thick. Dunno but so incoherently and so surprisingly I took it more than half down in my mouth. The man got the shock of his life too but enjoyed. Did not stop me also. And then after a couple of minutes, when I realized what I have done, the guilt took over and somehow I managed to get down at some station other than my and took another train.
Till date I don't know whether he might have left his zip open deliberately or absent-mindedly but since then, I became bi-curios. I have mixed feelings about other men (to have them or not) but couldn't make up my mind. Wish to try though.
Then I found this forum and am happy I MIGHT find someone from my city.
