Wife 's trip to work - 3 days away

I've written before that my wife must be safe with her boss.
She's beautiful, blonde, 30 years old... (see these and other pictures in other stories)
I found out that her boss is hitting on her way too much, and I'm starting to believe that she's hitting on him at these sporadic events.
Today she had to travel for work to a place far away from here, and she'll be back in three days with three other people, one of whom is her boss and the other two are a couple, so... it'll be two hours and two women there.
In what she saw, when she was packing, I saw her panties... she didn't even have a big panties... only dental floss panties, laces, lace etc.
After work today, there's a party at work, and you told me you had to go.
Coincidentally, last week we had a conversation, in which she told me about the relationship... that it was warm etc... I said that it would be an idea if she met other men, (she doesn't even think that I know about her with the boss) that it would be cool for the relationship if she tried another relationship... she thought it was strange but didn't say a word of denial.
I'm sure it's not the first time she'll give it to him... but this time she'll definitely give it, knowing that I'd approve... will she tell me? Three days traveling with her boss? Having only him to talk to these days?
