My Wife Wanted A Total Stranger

When she first told me about the fantasy I treated it just as that, a fantasy but a few weeks later she asked me if I found anyone yet. She told me Yes, really, she wanted a total stranger to have sex with her while she was helplessly tied up, I was thinking this was a bad idea. I told her okay, sure I will post an ad and see what we find then I remembered Chuck, old co-worker from about ten years ago who I would occasionally run into and even sometimes stop by his shop and have a beer with him.
Okay, look Chuck I said sitting in his shop asking him if he would be willing to do this explaining her bucket list sex thing to him. He said Let me make sure I get this right. You are going to give me a key to the hotel room, I go there and have sex with you tied up wife and she is not going to be mad or upset about this? Totally her idea I said. Went on saying how she wants a total stranger but I just cannot bring myself to do it that way and want it to be someone I trust. What are my limits he asks me, like does she not like to be spanked, tickled, anal, I need to know her limits because if you want this to be believable I just cannot go in there and be vanilla about it. Stranger would do something that was on his fantasy list also.
I talked with him about things done to her by me, she also had an ex who loved anal but she was not that crazy about it so maybe just fingers and I had no idea about the spanking but she was quite ticklish and did seem to like it. I was a little worried when he stared off to the side and said " I have always loved feet" then said he would do it.
Few weekends later I handed him the key card down in the lobby, told him to call me when he was finished and I might be a few minutes as i was going to this restaurant a few miles away, he said Okay and headed to the elevators. I watched the door close and hoped she was going to really enjoy this then walked to my car and went to go eat and watch something.
Few hours later I looked at my phone again thinking, Holy shit he is having a great time with her for sure and I think about twenty minutes later my phone chimed with a text saying I he was done and she was spent but she had asked him to untie her hands before he left. So I paid my bill and headed back to pick her up, I went into the room and heard the shower going, popped my head in to tell her I was back and she looked very happy. After telling me a few things her eyes went wide and she said My God that guy has a huge foot fetish, nearly peed the bed from him tickling, sucking and nibbling on them then she turned around and said Look at my ass cheeks, he spanked me also. She went on saying she was really nervous when she heard the door open and felt his first few touches, honestly thought it was just me returning since she was blindfolded but when she asked if it was just me again after some serious foot attention he lifted up the blindfold and smiled at her then put it back in place. She told me a waive of fear and pleasure just washed over her seeing a total stranger and the full realization that he had complete access to her without me there. She asked me again, you were gone right? I said Oh yeah, even have the bill from the restaurant to prove it. She went on telling me all about it and said the only thing he did that sort of surprised her was gagging her several times while making her suck his cock, after the first one she sort of tried telling him he went in to deep but he just shoved it right back in there gagging her again and again then stopped. She told me Yeah, I was a bit worried there for a minute that he was just going to throat fuck her but he stopped so that was good because he was BIG she said with wide eyes, sorry honey but he was big. She pulled up her breast and showed me a hickey saying, yeah he loved my breasts also, left some love bites here and there as she moved them around with her fingers.
So I was really happy that he gave her enough of a thrill and was not easy going on her but also did nothing so over the top she was scared out of her mind. Then she hit playfully hit me and said We have to do this again! What a thrill!
