I suspect most blog posts on here are made up fantasies but ive been told to share something that actually happened to me today. I was on my way home on the underground, i was in the last carriage which had just me and a coulpe of other people; a middle aged woman and a black guy in work overalls. There were other people further on down the train. i noticed the black guy opposite me was staring at my tits, i dont have very big tits but i was wearing a low cut top and had my boobs pushed up. anyway after a few more stops he's still staring at my tits but the lady gets off and now its just me and him in the train carriage but a handle of people further down the train. After a while i build up the courage and just blurt out "im sorry my tits are pretty small" with the cutest smile i could manage. "Damn right girl" he said and continued staring. "So what do you think, how do you rate them?" I was getting pretty bold then, it didnt hurt that i had been turned on all day and had dripping wet panties. He said "I'm going to have to feel them if i'm going to rate". I just nodded, at that point it was an out of body experience and i had no control over my actions. He stood up and moved over to sit next to me, he sat so that he blocked the view of the rest of the train and the passengers so no one else could see what was happening. he sat and was probably a whole head taller than me and i just sat looking up at him and his big grin. He reached out and started grabbing at my tits, he squeezed and rubbed. His hands were massive and my tits are so small he grabbed my tit in one hand. After a few moments groping me he said, "you white girls are all sluts arent you, you let guys do anything". "Yes" i said. He reached down my top, he wasnt very gentle and did the same thing but under my bra and top. He squeezed and pulled then laughed as i moaned when he played with my nipples. Again he wasnt gentle he pinched and squeezed and pulled at them, they were rock hard and stinging. I just sat there eyes closed moaning. Then he pulled one side of my top down to reveal my bare breast, he sat and looked at it and finally said "yeah, i'd say three out of ten bicth" then just got up and walked off. I was left scrambling to pull my top up and carryed on going home but was rock hard nipples and a river flowing out of my pussy.
