It had been years since Mark had played over at Mrs. Yang’s house with her son. Those years had done him well. He had grown nearly two feet, put on plenty of muscle, and gotten a job as a personal trainer. But if the years have been good to Mark, they’ve been excellent to Mrs. Yang. She’s as smoking hot as he remembered. She wants a little more confidence and definition? That’s Mark’s specialty.

How could he have known what was going to happen when he took Mrs. Yang as a client? I mean sure she had always been irresistible, but now she seemed… insatiable. Plus that nutritional supplement has got to be doing something to her. Yet the chemistry is undeniable. In the span of a few lessons, she’s already benching double her starting weight. Who knows what will happen with a few more? Soon it’s all he can think about, watching and worshiping as his muscular milf swells bigger.
