I didn’t expect this from my wife

So my wife and i were having adult fun last night. during sex, she told me she felt naughty because one of her co workers recommended a regular movie for her to watch, and she threw it on the day before. I was like umm, okay … She then goes on to tell me she was imagining fucking him. I didn’t say anything i just kept pounding. I am still thinking about it this morning at home and she went off to work. i don’t think she will do anything plus she wouldn’t risk her job or her marriage. So i believe her when she says it was just a thought that she used so she can cum. p.s. I asked her what his name was and after she told me she started riding me harder. I liked her riding so why would i complain.
