In the Park

I have the following dream:
I am sitting on a park bench and reading a book. At some point, a younger couple comes and sits down next to me. She is very pretty and he doesn't look too bad for a man. I try to continue reading my book, but I can't deny that I have to listen to both of them. They are arguing. She's angry because he did something that hurt her. But it's not easy to hear this from the conversation - the only thing I can make out is that he hurt her. They both try to keep their feelings under control. At some point, the woman turns to me and asks me bluntly: "What would you do if your wife had slept with another woman?"
"Oh," I begin, "I don't know, because I don't think my wife would ever do that." "In other words," the woman replies, "how would you react if your wife did?"
I think they both realize that I'm a bit uncomfortable and that I've gone red in the face, because she starts to smile and looks over at her husband, who is also smiling a little. "Well, I don't know if I would be annoyed or find it stimulating, probably more the second."
"If," the woman continues, "your wife caught you fucking another man, how would she react?"
"I wish," I reply, "that it would stimulate her too. But I've never done it before."
"Hmm - would you like to experience it, i.e. would you like to have sex with a man?" the man suddenly asked me. Again embarrassed, I said "Yes, yes, I would like to do it once, but I wouldn't know where to find a man and how to start" was my answer.
The woman looked at the man and he nodded. Then the woman said, "My husband cheated on me with another man - but I don't like this man and we actually both have an agreement that we will never have sex with other people without telling each other. I want to punish my husband. Would you help me with that?"
I look at both of them in total bewilderment, embarrassed and ashamed on the one hand - on the other, I can feel the excitement inside me. But I answer "I don't know". The woman then leans towards me, comes right up to me and whispers in my ear, "I'll help you, I'll tell you both what to do." Then she kissed my ear and her tongue licked my ear. I immediately became so aroused that I immediately said yes.
She whispered in my ear: "I will give you the best sex of your life as long as you do everything I tell you to do."
I couldn't do anything but go with the two of them.........and my cock was so aroused that it was hard to hide it......
