I am sitting on a mostly empty plane, third row from the back. This part of the plane is almost entirely deserted, most people preferring to sit up front and closer to the exit. I was running late when I boarded, and headed for my usual spot near the back without noticing too many of the other passengers on the way.
A few minutes after takeoff, I notice that across the aisle from me, in the window seat, is a striking looking girl in tight jeans and a tight blue half shirt, sliding gently over perky little tits. Her belly is tan, her dark hair cropped short.
She and I are the only ones within 5 rows of each other. I steal a few glances over at her. She's reading some sort of romance novel and seems not to notice me. My imagination takes over and I begin to picture all sorts of nasty things I'd like to do with her. As a result, my cock begins to grow in my tight jeans, soon becoming quite painful in the cramped seat. I loosen my seatbelt, but that doesn't help much. I'm now imagining banging her in the lavatory, her ass up on the sink and her legs wrapped around my waist as I plow into her tight slit. I decide the pressure is too much, and I grab my jacket from the seat next to me and drape it over my crotch. Underneath it, I unzip my jeans and free that powerful erection, my hand sliding up and down as my pre-cum lubricates the shaft. This is exhilarating, jacking off while watching the subject of my fantasy, sitting not 10 feet away.
As I watch her, she seems to sense someone looking at her, and glances over, her eyes meeting mine and then slowly dropping to my jacket, which is mysteriously moving up and down at my waist.
Her hand goes to her mouth instinctively, and after an initial shocked expression, her look softens and a mischevious smile appears at the corners of her mouth.
