Masturbating in My Seat During the Plane Ride

I havent done this much in recent years, but in my teens and twenties I would usually masturbate while in my seat on most long distance trips over a couple hours.  Busrides and plane rides, it helped to pass the time and alleviate my horniness and Ive developed several ways of rubbing myself and can get off very discreetly when I choose too. I always choose the window seat when I can get it and this helps maintain just that bit of privacy I need to get off while traveling on public transportation.  I've masturbated over a dozen times to orgasm with people seated right next to me; typically women but on occasion guys too.  Sometimes I will have to get up and use the private bathroom to finish because I just need to really pleausre myself and stroke off letting go and spurting cum everywhere, but quite often I really enjoy passing the time secretly pleasuring myself without anyone knowing! I'm not going to be able to say for 100% that nobody ever knew what I was doing, but Ive never been caught or called out or anything.  I am pretty easy on the eyes and can be extremely nice and personable (when I want to, otherwise Im more often pretty introverted) so maybe that has helped on any occasion someone perhaps caught on to what I was doing.  I usually read a book when travelling and this provides such an easy cover- getting settled with my nose in a book seems to let people ignore me while still giving me slight room to occasionally fidgit while "turning pages"....also something to have in my lap and use to cover the enormous erection I have to strategically slide down my pants leg or up my tummy under my shirt.  The airline blanket comes in PERFECT for this too, not only to help me cover up, but to stay warm and comfy, and provide and nice soft place to rub my swollen cockhead and extremely easy cleanup to simply rub and spurt cum into the blanket! Of course I typically manage to be discreet and slow, slowly maneuver my cock into a comfortable position where I can just rub my swollen cockhead with one or two fingers; no extraneous motion from my hand, elbow shoulder or anything that might give me away....   unless I want to ;)   I have on occasion made my motions noticeable to the person sitting next to me when I thought it might be acceptable!   Ive had one quite attractive woman, about ten years older than me at the time, fall asleep next to me while I read, providing the perfect cover to pleasure myself.... I let myself get a little carried away and was actually rubbing my leg against hers as she had relaxed into my space as she went deeper into sleep.  It turned me on enormously to be touching her while pleasuring myself secretly and I also made contact with her arm to arm.  Well it turns out she either wasnt as deeply asleep as I thought, or whatever, but at some point she became aware of what I was up to and returned the pressure against me leg to leg and arm to arm...even going so far as to methodically squeeze her legs together and try to rest her hands in her lap and press into herself as unobtrusively as she could.  I let her feel my exact rubbing motions through my arm as I rubbed the tip of my penis, and knew she was enjoying our little game by the rosy blush in her face and neck and elevated breathing.  I went so far as to boldy pull my entire cock out of my pants unerneath the blanket in my lap and to fully rub my entire shaft with the soft material as I pressed aginast her leg and arm, letting my breathing get way more elevated than I ever would in public when I do this.  I essentially let her experience my now-not-so-secret public orgasm right along with me- spurting copious amounts of sticky semen into my blanket, still having my book nearby in case of someone suddenly walking by, but blantantly letting her see me rub the outline of my turgid erection and actually soak through the material of the thin blanket....turning the medium blue fuzzy material and obviously spreading dark blue stain as I gripped my cock head and breathed very heavily for her as I rubbed her leg with mine.  The smell of fresh ejaculating semen was incredibly potent in the stuffy cabin air (this is usually my main concern when I cum publicly, that and of course the wet sticky mess!)  She was nearly matching my own pace of not-so-sublte movements and heavy breathing; squeezing her thighs together and pressing her folded hands into her lap.  I think she waited about ten seconds after the last of my cum stopped growing into the obvious dark wet patch on my blanket over my completely obvious erection before suddenly getting up and heading back down the aisle where I saw her enter the nearest bathroom stall.  She didnt return for about 20 minutes, ample time for me to clean up and return to normal passenger mode.  I think we only exchanged the most simple hello or even basic nod when we first took our seats before takeoff and nothing was said upon her her return to her seat afterwards.  It was hot as fuck getting off with a complete stranger and knowing I likely inspired her to do the same and likely go finish herself off in private!
