Knock Knock, Housekeeping!

In my 20's I was travelling on an official military duty and staying in a "temporary living facility" or billeting as we called it.  Like most 20-somethings I often woke with morning wood.  On this particular trip, I was working a later shift so morning for me was actually closer to lunch.  I fired up my laptop and launched into the whole reason the internet was created, endless varieties of porn!  In an effort to keep my self-pleasure secret, I plugged my earbuds into the laptop so no one walking by my door would hear the canned moans and squeals.   After a half an hour or so of alternately squeezing and stroking, basically edging before I knew what that was, I decided to try out some of the complimentary body lotion in the bathroom.  As a long-time masturbator, I seldom used any lubricants because of the additional mess it would cause, it was hard enough to deal with all the semen and not get caught.  Having the freedom of young adulthood and privacy of my own room I figured I'd branch out a bit and try it out.   I settled back into the bed and resumed a compilation video I had found that was really "doing it" for me.  Once I was fully hard again, I slathered some lotion into my hand and worked it up and down the shaft slowly, really enjoying how the friction was different with lube.  I mimicked the velocity and stroke length I saw on the screen with my right hand while my left hand was alternately cupping my balls and holding the base of my shaft to keep my skin tight while the lotion smoothed out the stroke.   It didn't take long for this new sensation to build up, as my balls drew up tight I could feel the pressure building deep within.  I shut my eyes, drove my head backward into the bed, arched my back and began shooting streams of cum into the air with wild, reckless abandon.  I felt the warm splashes hit my face, neck, chest and eventully stomach as the velocity died down.  I continued pumping very slowing, squeezing out all the cum I could while enjoying the post-orgasmic sensitivity of my cock head lubricated by lotion and semen.  When I opened my eyes I was immediately shocked, confused, embarassed and secretly excited all at once.  A middle-aged, dark-haired (Korean maybe?) housekeeper was standing just inside the room with the door mostly shut, her hand still holding the door knob, looking right at me and the mess I had just created and smiling the friendliest knowing smile I could have imagined.  I have no idea how long she had been there or how much of the waterworks she witnessed and she started saying something before I could yank my earbuds out but all I caught was "some towels" as she stepped halfway out the door.  I was trying to get untangled from the bedding/laptop/earbuds when she came right back in holding a few clean white towels.  She walked right over to me holding them out with a big smile on her face, I reached for them but she said, "no no, I clean you".  She laid one towel on the bed beside me then unfolded the one she was holding, she started on my face, wiped my neck and chest, swabbed my stomach and said something like "you make great big mess, lucky I bring extra towels".  She stopped towel-mopping me at my stomach and laid the jizz soaked towel on my crotch and said she'd come back later to service the room.   I saw her several more times throughout my stay and she always gave me a friendly smile but never said another word about it.  I did repeat my morning sessions in the hopes she'd walk in on me again but it never happened.  I think she figured out when I left for work and scheduled my room accordingly.  Ever since that happened I have fantasized repeatedly about her watching me, walking in on me and wondered if she ever thought about that when she masturbated.  I am a very shy person by nature but ever since that experiance I have had a continual exhibitionist fantasy of being watched but I'm way to afraid to risk jacking in front of random strangers for fear of police reports and a criminal record.
