In the heat of passion

So, I finally had my super duper slut moment.  I was in a restroom...oh this can't start out good with a preface like this...I was in the restroom at a shopping establishment and this guy comes in.  He's a hot daddy type...early fourties maybe.  Tight black shirt, greaser hair, tatted sleeves, tight jeans.  I'm standing at a urinal and he gropes my ass.  I turned to look at him in shock.  I got all flushed with fever.  I don't eat off the floor of a bathroom.  He walks into a stall so I zip and shrug off my conscience and followed.  The door closed and he lifted me up by my ass, my legs wraped around his waist, we kissed intensely, his hips grinding into me all hard, we're both tumescent, then I just start getting flop sweat, it's getting so hot and humid, his hands go down the backside of my jeans and cups my cheeks, then I get all scared.  I pushed off and quickly walked out.  This was such an unusual circumstance.  I walked away with a hard on and a lesson.  I'm just not the kind of guy that can get it on in a Nordstroms bathroom.
