I was sitting when a man and young woman came and sat to my either side. They were not together. After sometime, I the train went slow and stopped whi...e the announcement was brought made in Italian. I turned to the guy on my right to ask what was the matter. He responded in Italian and in a very rude way. I turned to my right and hesitated. She was reading some book and looked towards me and smiled. Wow..What a smile it was. With her specs on..she looked even more beautiful. She said that the. It works and his hand is under me, two fingers delving inside, stroking and my body starts to sync with it finding the rhythm of his fingers, and then wet with my juices his fingers tease the rosebud of my arsehole and I push back willing them entry. "Not yet," he says. "Bad girls have to be punished first." We both know who is in charge and who is sub; I’m so wet I want him to touch me everywhere and I think I want him in me. Instead he instructs me to remove my clothing; I pull the dress. As he was shorter than me by a couple of inches, with her high heels on she could reach him easily instead of having to crane her neck which she had to do with me. As they kissed he continued to massaged her breast and finger her pussy as she held his cock in her hand. He wasn’t fully erect yet but he was certainly rising towards the promised eight and a half inches. His tanned skin and strong frame contrasted so well with her white and delicate body. She pumped his cock faster as it grew in. No. please don't put it in my ass, I don't do that kind of thing!" she pleaded."Are you sure?" I asked still running my finger around her knot."Oh god!" she moaned again "No, Yes. I mean no, please don't!" she said again.I could see she was clearly conflicted, but not wanting to ruin a good thing I simply replied "Okay, how about I just tease you like this!" I said running my finger around her ass again."Oh , yes! yes! keep doing that! I like that!" she replied happily.So I carried on fucking.
