But as he took me in his mouth the door bell rang, he lifted his head and turned to the door. “No, don’t stop, please?”The sitting room door ope...ed and Mich popped her head round saying “Don’t bother, I’ll get it,” then looked down, “ “Oh, OK. Save some for us.” Doug returned to my cock. We could hear Mich talking in the hall, she sounded excited, then the door opened again. “It’s Mike, the barman.” She called as she opened the sitting room door. “Come and join in Mike, the boys have already. Let's go upstairs and carry this on in my bed.” We went upstairs and spent the rest of the weekend sucking and fucking.***5: A threesome The following Friday was Amanda's last day at university she had a month off before she started a job at Truro hospital as a theatre nurse. I was wondering if her mum had said anything to her about our weekend in bed together. If she had Amanda did not let on that she knew. Her Brother had graduated 3 weeks before Amanda and had started work in. Today, mistress and David have gathered together the tools, in the way of really bad people, to test me. To see if I can survive the worst they can imagine the blackmailers could throw at me. They’re even going to video the whole ordeal. I should worry that something will go wrong and the video will make it to the internet. Instead, I know that if it does, it does. A week ago, the very idea of a video would have been more than sufficient blackmail material by itself. Now it’s just a thing. If. Her confession filled my mind.I stared at her, my thoughts racing, my balls growing so tense, so full of cum. That ache grew at the tip of my dick. “You really want to have sex with me?”“Yes!” She tightened her arms. “I know it's wrong and disgusting. I know I shouldn't have these depraved thoughts. I just can't help myself. They consume me. I want you so badly. I want to make love to you. I'm such a terrible person.”Incest was wrong, and yet... She wanted me. A girl, even if she was my own.
