He placed his hand inside his trousers and felt himself getting hard. He unzipped his jeans and slowly took them off, not wanting to wake either of th...m. He pulled his cock out of his boxers and began rubbing his shaft with his hand, all the time with his eyes on Tina’s arse.She shivered slightly so he moved to his side and moved closer to her. He placed one arm on hers and pulled her to him slightly. She mumbled in her sleep and moved herself into him, her arse, now firmly on his naked erect. Julia and Ben had made love before dinner because they knew their friends would be coming shortly and they wouldn't have another chance to be alone for a few days. But as they lay together in bed, spooning, Julia felt his cock growing hard against her back.She smiled and turned around to face him, reaching down to touch him as she leaned in to whisper in his ear. "Mmm, I'm going to miss you, and this," she said softly, her fingers running lightly down his shaft, dipping the tip of her tongue in. .." Hush, John; it's all right. I know you're not a pervert. It was my fault both times. I should have locked that door, I didn't even realise I hadn't. My fault! I'm sorry. The second time, I should have at least knocked on your door and not come bursting in. You're entitled to your privacy, but I was in such a hurry to apologise for the first time. Again, my fault: again I'm deeply sorry. I've embarrassed you twice."About what you were doing, Son, it's no shame to masturbate. It's natural,. I want to have our child. It’s important to you so it’s important to me but I want to be the first. I want you to impregnate me before Marg. If you can’t get me pregnant before her then I will find someone else who will do it for us.”I felt a sudden fit of anger. Here was this woman who had cheated at every opportunity through our marriage. I had raised someone else’s daughter not knowing for sure if she was mine for a good many years and here she was threatening me. There could only be one.
