About six months ago I was on a 9 hour flight to a far off land and I was flanked in the plane by my best friend and a roughly 30 year old French man. We hadn't exchanged any words except a polite hello at the beginning when we sat down.
When it was night time and the lights went down I struggled to sleep because I rarely go on aeroplanes and I was not used to sleeping sitting up, and as I am rather tall, I was very cramped so I was just sitting there. I probably looked asleep though.
A few hours went by. Then, I felt his arm next to me making rhythmic movements. I looked over and saw that he had made a sort of tent over his lap with his blanket. He was masturbating, I was sure of it. I could feel his arm going up and down, stroking his erect cock gently at first. I didn't dare look at his face, for fear that he would stop, and I knew he thought I was asleep.
I was seriously turned on by the supreme naughtiness of it. This man next to me was aroused and masturbating right next to me! I felt my pussy get really warm and I was squeezing my legs together to try and get some pressure on my tingling clit.
My best friend was fast asleep. The man's arm movements got faster and more obvious and I was getting really wet, I could feel my thong getting soaked. I wished I was wearing a skirt so I could maybe masturbate under my blanket, but I was wearing a full length dress, so there was no way in really.
His movements got frantic and I caught a glimpse of his face, his eyes were shut and his mouth was slightly open. I thought how those lips would feel on my clit.
His face scrunched up as he came, and I looked away and pretended to be asleep. He waited a while then got up to go to the loo. While he was away I ground my pussy into the seat. When he came back I went to the toilet. He looked shocked, because it must have meant that I was awake while he was wanking. This excited me more.
I locked myself in the toilet and hitched up my skirt. I pulled my thong between my pussy lips and ground into it. I felt really naughty.
I whipped off my thong, and sat on the toilet seat. I was so wet. I rubbed my clit and fucked my pussy with my other hand, thinking about the wanking man. I wanted him to lick my clit in the aisle of the plane, with everyone watching.
As I reached orgasm I gasped and shuddered. I felt so luxurious and sexy.
When I went back to my seat, I squeezed right past the man. I looked flushed and my body temperature was high after my intense masturbation session.
I like to think he could tell what I'd been doing.
