My stepmom, Kymber, and I are sharing a bedroom during our clan vacation, and she is concerned.  She is concerned because she knows that stepsons of a certain age need to relieve stress in the evening before bed, and she wants to make sure her stepson does it the RIGHT way.  So, my stepmom tells me how she wants me to jerk off, from taking out my dick, to counting me down to cumming from 10.  My stepmom is a sexy instructor in her pink silk nightie, and she even takes her MILF tits out for me so I can stroke them until I cum all over them!
