I stretch, pull off my headphones, and put them away. I look across the aisle and see that a female had taken the window seat across from me. She was ...looking out the window, so I was only able to see her long flowing dirty blonde hair and the back of her clothing. She was wearing a blue t-shirt and jeans. Something a normal person would wear on the train. She certainly looked young, maybe my age (20). I then looked past her at the window and noticed my reflection was looking back. I saw her. I then quickly got the vibrator and turn it up high and balanced it on her pussy again. She moaned. I licked. Actually, licked the 12-inch dildo. Tasting every drop. To me it was the taste of success. I put on my coat and importantly took off my gimp mask. One last look around the room and opened the door. As I closed it, I heard:“Big D… you left me tied up with a vibrator on… you horny b**st. You horny b**st.”I went into my room opposite quietly. I felt a mission was completed revenge was. “Come on. It will feel good,” I said, “You’re so fucking hot, you know.” She gave me the most generic lame response ever, simply, “I’m waiting until marriage to do stuff like that.” I continued “cuddling” up to her, rubbing at any piece I could get my hands on. I could feel my cock beginning to stir and fill in my jeans. It was the idea of her very innocence, the fact that she probably really was still a virgin, coupled with her incredible hotness that just pushed my heightened mind over. We chat for a little bit longer and then the subject changes to the events from a couple of days earlier...she asks me if i feel guilty because of what we had done. i was honest and said a little but i explained it had always been one of my fantasies and because it came true i was delighted, she was relieved because she felt the same way too and then she says she had never been fucked like that before and she said she can't get it out of her mind, we are flirting away and she tells me we will.
