"I don't entertain often. I figure I better do it right."

She does end up shifting her body so that's she's lying on her side next to him. Part of that is because she's afraid that if she fell asleep on top of him her back would hate her a bit in the morning (she's still a relatively young woman but sometimes it's hell getting old) and part so that her hand can roam over the entirety of his chest.

She's glad that he doesn't roll away, but she would never stop him if he wanted to. Something like that isn't even considerable. They can see whatever this is through until one of them doesn't want to anymore. It might be a little more complicated if more intense feelings develop, but she'll deal with that if it happens.
