New Guy Needs Question Answered?

I'm pretty new to all this and have a question:

My wife went to Spain for a week without me. When she got home she was dressed very sexy. We fucked that night and her pussy was very loose and she was wetter than ever - she was extremely in to it and even asked me to slap her ass and wanted me to put her black dildo in her ass as we fucked - which I did and she came very hard. Then she wanted to do it again an hour later.

Do you think she got fucked while she was gone? i mean her pussy was a lot looser than before she left. I know she met someone there because she has been sending someone she met e-mails.

What do you think? What do I do know? it turns me on.
