No ordinary flight

I was on the plane ride home, it was one of the smaller planes, 2 seats wide on either side, I have the window seat and nobody is beside me. Behind me though is a mother and her baby as well as a very pretty woman, in the seat next to her. I'm going about my things and I have jeans on so it's hard to conceal the growing bulge going down the side of my right leg, not only because of the vibration of the plane, but because I haven't cum in 7 days... But no biggie, nobody is beside me. Next thing I know the sexy lady comes and sits next to me in order to give the mother and her baby more space, perfectly fine, but now I'm crossing my legs trying to hide the obvious. She's watching a movie, I'm listening to my book, but my legs are going numb from being crossed so fuck it, I uncross them, and set the seat back... She's still into her movie, oblivious to the bulge beside her, so I nod off, trying to relax and go soft. I'm in and out of consciousness, trying to sleep as the sun rises on the early flight, and I start noticing that her attention is now divided between her movie and what's beside her. I get kinda turned on knowing I'm basically an exhibitionist on a plane, and that only makes the bulge bigger. We didn't talk at all, she pretended to be into her movie, but when the plane got to the gate she says "thanks for letting me sit here, I really enjoyed the view, I'm Allie btw" and hands me a piece of paper with her number. I just said "glad you enjoyed the view, Allie" and she picked up her things and went on her way.
