A beautiful, "highly conscious" mature woman comes to her personal trainer's home for training. "Today, let's start with a stretch I invented that is extremely effective for toning your figure," she is told, and she changes into clothes that show off her curves. The trainer assists the mature woman with a stretch that involves rotating her waist, but then says, "I'm going to check how tight it is," and starts touching her crotch and anus directly. As he supports her by grabbing her breasts and buttocks, the poses he demands from her get harder and harder and more erotic. And then they just keep going straight into sex! I spied on the whole thing.
