While they worked on that, the phone rang. Sylvia’s mother went and answered it. ‘Oh, hello, Milton,’ Jason heard her say. He was surprised to f...el anger and jealousy surging through him. ‘Sylvia’s been gone most of the time and so has Brenda, over at the riding academy,’ Karen said, apparently in response to a question her husband had asked her. Jason wasn’t sure what to do. He didn’t want to hear this conversation. The last thing he wanted was for her husband to intrude on the time he had. Oh daddy," she cried out to me, turning her head to kiss me as we held each other still. The climax ran throughout her body, and we slowly began to grind together, her hips tilting back at me as my cock moved to and fro.My fingers kept tugging on her nipples, and I again slid my mouth to her slender neck, kissing and sucking on her as we started to fuck again. Her pussy had opened up a little more to me, and I began to drive into her when she surprised me."My ass, daddy.....put it in my. I want to do it." Tina smiled, and Cindy felt a little embarrassed by her eagerness. Well, the Program was about expanding sexual awareness, and she was certainly doing that!As usual, it was difficult for her to keep her eyes off her Mistress as they went through their workouts. Tina's skin gleamed, and Cindy longed to lick the damp skin of her breasts. When Tina did her splits (with a towel under her) Cindy almost moaned out loud. This was such torture! Somehow, it seemed as if Tina knew what. I realised that the way that I was sitting (and never wearing pants) she was looking at the gap between my shorts and my thigh and was either actually seeing or trying to see my cock. I tried to move to frustrate this but didn’t want to draw attention to my knowledge of her curiosity and my efforts only served to open the gap still further and given the warmth of the day I realised that my cock was tumescent and she would have a very good view and there was nothing that I could do except squirm.
