My friend, his wife and I, the three of us are in bed for the first time

Last night I went to visit a friend we had talked to and he was not at home, I attended the woman who is always very nice to me. she told me to wait and invited me for a beer. she opened one too. we started talking and as my friend was not coming, we had another beer, then another. I was a little drunk and my friend's wife was having a good laugh. then she approached me and pulled on some clothes she was wearing, saying that she smelled very hot. she brought her face close to mine and I kissed her. I don't know how it happened, but when my friend arrived I was in bed with his wife. I tried to get up and apologize, but he undressed and joined us. the three of us had a great time together. so i asked if he hadn't bothered and he told me that his wife hadn't asked him for an experience in a long time, and that they had planned for that day, which is why he came back so late. if I don't accept the offers, he won't say anything not to get engaged. so, from time to time, we agree that the three of us will meet.
