Supported by subway and more

I'm Brenda, I'm 25 years old and the story is as follows: I always leave work late, around 10 pm, and my boyfriend comes to pick me up every time, we take the subway line D... The next thing that happened was a normal day, I was coming back with him on the subway, it was crowded, I was sitting down and he was standing in front of me... chatting, when I saw a boy behind him, sitting in the seat across from mine, not very handsome but decent-looking, tall, dark-skinned, with a nice smile... The thing is that this boy didn't stop looking at me, I tried to ignore him but we kept crossing gazes, he was attractive... We kept looking at each other more and more, until there came a moment when we would stare at each other for 3 or 5 seconds without blinking, then suddenly we would just keep staring at each other fixedly, I even talked to my boyfriend while looking at him too... Until suddenly an old lady got on the subway and I had no choice but to give up my seat... I stood next to my boyfriend and stayed behind the boy... felt like he was looking at me all over my ass from behind... until suddenly I felt someone standing right behind me, looked through the minimum reflection of the window and it was him, he had stopped and was standing right behind me... Inside I thought this guy is crazy, my boyfriend was beside me, and although he was always a bit shy, almost timid, I thought he would say something about this situation... I was holding onto the subway handle and the boy behind me was like my boyfriend, supporting me, without any shame, I was shocked, didn't know how to react and my boyfriend's stupid boyfriend just kept talking to me like nothing was happening... Time passed and the boy kept supporting me more, it was obvious, on top of that he had a hard-on and I was wearing leggings, I could feel everything, clearly I started to enjoy it and if my boyfriend didn't say anything, screw him... I leaned back strongly and applied pressure backwards so his cock was practically stuck between my ass cheeks, it was getting so obvious that my boyfriend finally noticed but instead of saying something he got uncomfortable and looked away. side, while this guy was supporting me all the way... Until a moment when he says we're going back further with a scared face as if he had been thinking of something to get me out of there, but I didn't want to leave, I said no love there's too many people here we're fine... He got off at two stations and I kept going until the end... The trip continued and the guy from behind was supporting me all the way, even to my stomach on his back as we were stuck together... My boyfriend got off at the next station, but I'll tell you what happened in the next story.
