Swedish Massage with Happy Ending

I once had an opportunity to go to a health spa for a massage (my first time and only time).  This was not a sleazy massage parlor (I've never been to one), but an upscale spa which offered therapeutic massages.  When I arrived at the spa, I was assigned a female masseuse by the woman at the front desk and she directed me to the private room where I would receive my massage.  The masseuse provided a fluffy white robe and a pair of shorts and told me to change into them, and then left the room. After a few minutes, she knocked on the door and asked if I had changed.  I said yes, so she came in and told me to remove the robe and lay on the massage table and then she began the massage. She had me start on my back and then flip so that I was on my stomach.  Over the next 45 minutes or so, she gave me a great massage.  The masseuse, who looked to be round 30, was tallish and somewhat plain looking, but had an athletic, almost masculine body.  She hand strong hands, not surprising due to her profession.  She used some type of warm aromatic oil out of stone dish, at times draping warm towels over parts of my body that she was not working on.  I found it very relaxing. At the end of the massage, she told me she was done, handed me the robe, and said I could get dressed and head back to the front desk.  I remained on the table and, as she left, she closed the door behind her.  I stood up from the massage table while removing the warm towels and put the robe on.  As I was doing this, I realized I was getting an erection. I was in a nice state of mind after feeling her expert hands use the oil over most of my body.  I decided that a little more massage would be nice before I left.  I removed the shorts and untied the robe, letting it fall back onto the massage table.  I was now standing totally nude, leaning back slightly with my butt resting on the end of the table. I reached over and took some of the warm massage oil in my hand and began sliding my hand up and down my cock, using the warm oil as lube.  It was a great feeling, and there was the added rush of jacking off in this public place (even though it was a private room). Since they would be expecting me at the front desk I was under a little time pressure, so imagining one of the masseuse's strong hands wrapped around my cock, I jerked off until I came in nice repeated spurts of cum.  I caught my jizz in a towel that I grabbed at the last second. After that, I tossed the towel, robe, and shorts into the laundry bin, got dressed, and left after giving myself a great, unexpected, happy ending.
