I am not sure but I assume it must have happened last night. A few months ago, my wife met a man who is an artist and shares her passion for art. They became good friends and I let her know that it was Ok to get intimate if she wanted. This weekend they went to an art show that was out of town and shared a room Fri and Sat night. Before she left, she verified that I was Ok with it and indicated she might if they were in the mood. She called Fri to let me know she got there and last night to say they were about to go to dinner. She did not say if they had had sex and I did not push it. She will be back this evening and I assume that I should have a good idea then. I can not imagine that they spent two night together and did not have sex. She may not give me any details but I think she will at least admit to having sex if she did. And yes, I am anxiously waiting to find if anything happened.
Nice!! I'm happy for you. I hope your wife got laid. Be sure to share with the class whatever info you get.
