Almost twenty years ago, I spent a year in Australia. While I worked for a lot of that time, I spent the last two months travelling around backpacking and experiencing the whole outback thing. Toward the end, I needed to get back from Cairns to Sydney and ended up using the overnight bus.
When I took the only seat available there was a friendly but not particularly pretty girl sitting at the window. We chatted on and off for a time and then she fell asleep. I didn't remember falling asleep myself but when I awoke from my doze I found that she was lying on my shoulder and that our arms were somewhat entwined. Feigning sleep I moved my arms up and cupped her breasts gently. She continued to sleep but made encouraging sounds. I know this sounds a bit far fetched but it really happened.
After a while she turned toward me opened her eyes and leaned toward my face. We kissed gently and then more passionately. She told me that she had been without a boyfriend for ages and that she loved the way we had been asleep. After a lot more kissing under cover of darkness we started to fondle a whole lot more and when she touched the obvious bulge at my crotch she looked at me with searching eyes.. I nodded to please go on. She unzipped me and continued kissing me while she stroked me. Then it was my turn. When my hand slipped inside her panties I found her beautifully moist and aroused... my first touch caused her to gasp but she grabbed my hand and pressed it more firmly against her.
From there she simply used my hand and fingers to get herself off. With outstretched legs she panted silently toward climax and ground against me as my fingers played with her lips and clit. She had to use her sweater to silence her moans as she came and while our activity seemed oblivious to those around us we came close to wakening our nearest neighbours. When she had recovered she flopped over onto my shoulder and mouthed her thanks to me. I nodded toward my own problem, she smiled and said.. ooh sorry! From her mouth she coated her fingers and ensured I was all nice and wet. Then she started stroking, slowing and teasing, then pumping more vigorously until I too came in a series of gasping surpressed grunts. When we had recovered, we cuddled and fell back asleep.
In the morning, we kissed and wished each other all the best.
It was one of the most unusual but memorable experiences I ever had with a girl.
