When you asked her more about the party, and why she was getting home so late, all she said was that the party was really fun and she didn’t want to talk about it any more. And when you pressed for a few more details, she actually got angry with you, so you backed off. But the following Friday, without any prior discussion of the topic, she told you that she was going out to dinner that night with her boss, and would not be back until morning. Your brief attempt to ask her to tell you more about what was going on was met again with an angry response from her indicating that she didn’t want to discuss it and it was none of your business.
For many years I encouraged my wife to be with other men, but she wasn't interested. Then finally she had a one-night stand with a guy she met on a business trip and after that experience she eager to do it again. A few months later she met guy in a coffee shop near her work and began dating him on a regular basis.
Your wife spent most of last night with your best friend, but now he apparently is feeling awkward about the situation, so she needs you to be the one who gives him a call to set up their next get together.
What your wife really means is that the lingerie you bought for her to wear for her boyfriend will help get him rock hard, and that he’ll love taking that bra and panty off of her just before he fucks her.
