Amy Stone: 2 books

A middle aged, auburn haired woman picking up a slightly younger man at a quiet corner bar. They talk about being alone, and she talks to him about missing the feeling of having a man in her bed - missing the touches, the warmth, and of course, the sex. 

Liam has a sexual fantasy. But it is something so perverse, so unnatural, that he has never dared mention it to anyone. He wants to watch a stranger take his wife as he watches. He wants to fade out and watch her reach heights of ecstasy with a different man. He knows his wife would never be up for it….or would she?
