Dance Lessons Lead To Much More with Stepmom

My son is nervous about an upcoming dance because he’s afraid he’ll suck at slow dancing with his date.  since i’m the stepmom i offer to help him with some basic slow dancing moves.  during our first practice, as he grabs my waist and pulls me in, i feel he’s getting an erection. at first im shocked and my son quickly gets embarrassed.  i tell him he has nothing to be ashamed of and that it’s completely natural for a son to be sexually curious about his own mother.  for some reason that statement gets me wet.  before i can come to my senses, our clothes are being ripped off and we have lustful, primal sex!
