I engage in sexual activity with a girl who enjoys unusual sexual acts on a train

I was on a train to Chicago, feeling a bit restless and horny. I spotted a girl sitting by herself, looking a bit bored. I decided to approach her and strike up a conversation. As it turns out, she was into some pretty unusual sexual acts. She mentioned that she loved riding on top of a big cock, and as soon as we got off the train, she let me take her back to her place. Once we were alone, she took off her clothes and revealed her amazing big ass and big pussy lips. I couldn't resist giving them a good lick, and then she gave me a mind-blowing blowjob before straddling me and riding my big cock. It was an amazing experience, and I can't wait to do it again.
