Twenty minutes later I went back into the house but didn't see her. I heard her call my name and found her completely naked on my bed. This was the first time I had seen her naked. She had medium sized tits with perfectly defined nipples and I stood looking down at her. Her legs were open, and there was plenty of gaping pink on show. She put her hands behind her head, lifted her knees and opened her legs wider.
"Up boy" she said with a smile. I wasted no time, amazed that I was hard again, and entered her. Sara was looking down again where my cock was rhythmically pumping in and out of her cunt. She was very wet and there was plenty of sounds happening. She seemed to be enjoying herself, and it wasn't long before her eyes closed. One warm hand came round and cupped my arse and I upped the speed of my strokes.
She sensed my urgency and was meeting my strokes with thrusts of her hips. By now I was hammering my cock in and out of her and her hips were clearing the bed as she matched my rhythm. I knew she was about to come as her arms joined behind my back and she held her breath. She came explosively, and again she called my name. I couldn't hold any longer and also came. We lay just like that for quite a while, catching our breaths. I stirred first and pulled out and lay next to her. We were both wet from perspiration and lay apart. After a while I started absently rubbing her tits. They were firm and rubbery, and not quite a c-cup
She turned to me and showed me something I have never seen before or after. There were two lines of faint nipples running down to her tummy. She smiled and made me feel along the barely discernible nipples. Eventually she said to me that she wanted to go and wash before she left. I stayed behind, thinking about what had just happened. She seemed to be getting hornier and hornier by the day. My cock ached pleasantly.
It was Friday, and I said goodbye to her when she left. Her skin was glowing and she had a twinkle in her eye. I wondered what Monday had in store for us. Sara was going nympho on me. A completely true story. More to follow.
