Stranger orgasm [MF]

In 2012 I was on a bus from NYC to Cleveland Ohio. I was seated next to an attractive girl who appeared to be college age based on the NYU sweatshirt. I was 35 and married.
We had some small talk and then I drifted off to sleep. When I woke I was leaning on her. I quickly apologised, but to my surprise she said ” it’s fine, I don’t mind”. I was aroused by her response. She was listening to music through her head phones and humming along to the music. I placed my hand partially on her leg and she smiled. Her bottom half was covered by a blanket over her sweatpants. I gradually slid my hand under the blanket. Each time I moved my hand she would smile. She wouldn’t look at me, just smile as she looked out the window. I was rock hard by the time I reached the warmness between her legs. I rubbed her pussy outside her clothes. She smiled and kept looking out the window. She put her hands under the blanket and slid her panties and sweats to her knees. I thought I would cum in my pants!
I eagerly placed a finger on her clit and started rubbing. She sighed and smiled. I eventually had 2 fingers inside her. She was as wet as any woman I’ve ever been with. Over the next few hours I fingered her pussy to at least 6 orgasms.
She never touched me and we never exchanged names or numbers.
We got off the bus and not a word was said. We went our seperated ways and never saw each other again.
