I took what was on my hand and licked it off. I have never done that before and I liked the taste… I cleaned up my mess and went for the door it was...cracked open…. I thought to myself I know I locked it how is it open? I shut the door again and locked it I grabbed the handel and the door popped open? Oh shit I wonder if Zack saw me jacking off. I started to get hard thinking of him watching me like I was watching him. I calmed myself down and went into the livingroom and Zack was sitting on the. ‘Let me see your cock, Michael. I want your cock,’ she demanded, rolling me on to my back. My erection showed that I was in no mood to refuse. ‘While I suck it, tell me what you are going to do with it.’ This was the game she needed to play. I had told her I would try to help. My reaction once we had begun was neither conscious nor calculated. I found myself drawn into an erotic world that embraced me totally. Her lips closed round my knob, her tongue licked the tender underside. I surrendered. " And why not? After all you've given him -- I mean all the love you've given him and then he just walks out." I ... I thought he wanted to marry me. Oh, what a fool I've been!" The tears began again."Mom, your only mistake was trusting a guy like that. He was just using you, getting what he wanted then walking out the door." I'm afraid you're right," she said between sobs.I sat next to her and put my arm around her."It will be okay," I said quietly."Oh, Darin, I guess I'm too old -- just not. If not, then I had but one recourse. I would go to Doctor Fremd and confess what had happened so that he could help my sister, consequences to me be damned. It might well ruin everything else in my life, but unless my sister got professional help for the problem, it would eventually come out. There was at least a chance that Doctor Fremd would agree not to report it, though it was unlikely. If it came out any other way, there would be no containment, and it would certainly cost me.
