Older sisters are supposed to teach their younger stepsister and stepbrother all about the facts of life. I apparently missed teaching a lesson of great sexual importance to my younger step-sister Randy so here we are adults in my living room about to have the lesson up close and personal, with my husband. The situation is, her husband has begun to ask for hand jobs and my step-sister doesn't know how to give him a hand job with a happy ending. She exclaims she can barely get him hard let alone finish him off. I feel its my obligation to help her any way I can but of course first had to tease her just a little that she should have learned to master the techniques of a great hand job when we were in college. The truth comes out that she wasn't the slut I thought she was in college, she was just saying all the things she supposedly did with guys so she would sound cool. Well, years later here we are trying to give her stroking lessons on a banana.
