She took off her shirt

Remember my turning the AC off when my seatmate went to the bathroom? Well, now it was a bit warm, and as she prepared for some shut-eye, my seatmate pulled off her sweatshirt, revealing a thin-strapped tank top underneath. Her modest cleavage was on display, and her arms were fully exposed. But then--could it be?--she leaned forward to put something in her bag, and I could see her entire back! I was sitting in such a way that I could open my eyes without being noticed, and my close examination confirmed what seemed impossibly true: She was sitting next to me in only a bra. It didn't look like a sports bra to me, something that you might wear at the beach or on a jog. No, this was an ordinary, underwear-style bra!

Well, any thought of getting some actual sleep just flew out the escape hatch.

Even though the plane was full of deeply sleeping people, including the loudly snoring man behind me, my shirtless seatmate appeared to be resting unsteadily. Over and over again, I saw her head slowly nod and then start back up. I even tried to position my shoulder closer to her head on the off chance that she'd unconsciously lean it against me, but no luck. But still, it definitely looked like she was trying to sleep, and I appeared to be **** and harmless beside her.

I was sitting with my arms across my chest, my right hand on my left arm, which was resting on the armrest between us. Occasionally, her bare arm would brush against my hand, and she would move gently away. But then, her sleeping arm pressed up against me and didn't move, allowing for an extended press of warm flesh.

As we "slept" this way, my hand touching her arm, I positioned myself so that my face was about six inches from her chest. I carefully observed the details of her small breasts resting against her chest and traced the outline of her bra, scanning for (but, alas, not seeing) a nipple poking out. As I stared at her chest from mere inches away, my seatmate pressed up against my hand with even more ****, generating some very electric intimacy in my sleep-deprived brain.

(Author's note: Everything up to now has been 100% true. What happens next is the fantasy that would have made this low-key thrill even hotter.)
