It was an absolutely off the wall question and it caught me completely off guard.  I was sitting at the dinner table with my wife and we had been discussing how our days had gone when Fran said, "Honey, have you ever thought about me going to bed with another man?" 

Like I said, totally off the wall.  I put my fork down and looked at her. "What?" I asked, not believing that I'd heard right. 

"Have you ever imagined me going to bed with some one else?"

 I stared at her and the said, "What the hell is this all about?" 

She shrugged and said, "Just curious. I was talking to Cindy over coffee this morning and she told me that at one time or another most men think about their wives making out with other men.  Not that they actually do it, but they think about it, is that true?" 

I should have known that Cindy would be at the bottom of something as idiotic as that question.  Cindy and her husband Ralph were our next door neighbors.  They had moved in a year ago and Fran and Cindy had become fast friends.  Ralph was a nice enough guy, but if you looked up the definition of the word "slut" in the dictionary you would probably find a picture of Cindy next to it.  I did not have certain knowledge of Cindy's proclivities, but from what Fran told me and from the parade of men through their home when Ralph wasn't there I was fairly certain that I had her pegged.  What I hadn't figured out yet was whether or not Ralph knew.  I didn't really care for Cindy, but Fran doesn't choose my friends and I don't choose hers.

 "And on what does Cindy base this revelation?" I asked.

 Fran said, "I don't know.  Just from talking to her men friends I guess.  I told her that I didn't think you had thought like that, do you?" 

Well, I had no idea where Cindy got her ideas, but she certainly had me nailed.  Now I'd never really had any actual fantasies of Fran fucking other men, but I had wondered a time or two what she looked like when she was getting screwed.  Understand me on this one - I wondered what she looked like being made love to, but it was like I wanted to see her from a few feet away while she was making love to me.  I think Cindy was right about the fact that most men had a thought like that every once in a while.  Take last night for example; Fran is multi-orgasmic, we were making love and she was going wild under me.  I would have loved being able to stand off to the side and watch her.  That is not the same thing as saying that I want to watch her with another man.  But Fran wanted an answer to her question and I wasn't about to tell her that Cindy might have a point so I said, "No honey, I can't say that I ever have."  I thought that I detected disappointment in her eyes, but I didn't think much of it at the time.

The following Saturday I came home from a round of golf and I took my clubs down into the basement to polish my woods.  I heard Fran and Cindy talking in the kitchen and from the conversation it was obvious to me that they hadn't heard me come in:

Cindy:  "Honestly Frannie, I don't understand why you won't.  You know you want

              to and you know that the guys want you to."

Fran:     "I can't!  I want to, I'd love to, but I can't cheat on my husband.

Cindy:    Trust me on this one honey, he won't care.  He's just like other men and         

               the thought of you with other guys will get him all hot and bothered.  He

               will just want to fuck you more and more often.

Fran:       I don't think so.  I asked him if he ever thought of me with other men and

               he said no, not ever.

Cindy:    Tell you what sweetie.  If I can show you that he doesn't care will you

               come over on Monday and help me take care of Bob and Phil?  Bob

               likes you a lot and he would really like to fuck you.

Fran:      How can you prove that Dave won't care?

Cindy:    Do you have any K-Y?

Fran:      Yes, I've got the liquid and the jelly.

Cindy:    Fill your pussy up with K-Y, a lot of it, and get Dave to fuck you as soon

              as he gets home.  He'll want to know why and you tell him you just came           

              from my place and are horny.  As soon as he enters you he will think you

              were fucking some one else over at my house and that the K-Y is another

              man's cum.  I'll bet he won't say a word, he will just fuck you harder than

              he has in a long time.  If he does ask why you are so wet just tell him you

              were so eager that you filled up on K-Y so he could get right in.  If he

              seems skeptical have him taste what's in you and compare it to what is in

              the K-Y bottle.  But I'm telling you he will think he is following another

              man.

Fran:      I don't know.  I don't think it will work.

Cindy:   At least try it.  What do you have to lose?

I waited until I heard Cindy leave the kitchen and then I went upstairs and hollered, "Honey, I'm home." 

"I'm upstairs in the bedroom" she hollered back, "Come on up." 

I went up the stairs and went in the door just in time to see her closing the drawer that the K-Y was kept in, was she really going to see if I would gladly fuck her thinking I was following another man?  If I went along with Cindy's plan and let her think that I thought I was, would she really fuck another man on Monday?  I had to know!  Fran started undressing and I asked her what she was doing:

 "I'm hornier than a goat and I want you to fuck me."

 When I slid my cock into her pussy I got a surprise.  When I was in high school I got sloppy seconds several times and that's just what Fran full of K-Y felt like - like she was giving me sloppy seconds.  I'm sure that the surprise on my face showed and I'm sure that she read that surprise wrong - she read into it that I had suddenly realized that I was sliding my cock in another man's cum - that I had realized it and was continuing to fuck her without saying a word.  At that point Fran realized that Cindy was right and that she knew what she was talking about.  I was fucking her knowing that another man had just had her and I was loving it. 

Normally Fran is a little wild in bed, but that night she was fantastic and I don't know if it was because she was thinking ahead to Monday when she might be fucking another man, or if she was getting a kick out of my thinking that I was getting sloppy seconds.   We made love twice more that night and three times the next day.  I could have stopped things at that point by telling Fran that I'd overheard the conversation, but I just couldn't.  I had to know if Fran would actually be unfaithful to me.

Monday at work pretty much sucked since I couldn't think of anything but what Fran might be doing and what I would find when I got home that night.  Fran met me at the front door wearing nylons, high heels, and a smile on her face and a beer in her hands.

 "I've been horny all day honey and I've been staring out the window waiting for you to come home." 

She handed me the beer and went to her knees in front of me and while I sipped the beer she pulled out my cock and began giving me a blowjob.  I chugged the beer, put the bottle down and told her I would race her to the bedroom.  As soon as I slid my cock into her I could tell that I wasn't the first one to go there that day.  Again she was wild, wilder than she usually was, and we screwed twice before stopping for dinner.  After dinner we fucked again and she work me up in the morning with a blowjob and then fucked me before she sent me off to work. 

I had to admit that this unfaithful business had a lot going for it; I was getting more pussy now than I had been before Fran and Cindy had their conversation, but it wasn't setting easy with me. 

Tuesday I came home to the same thing only that time it felt like two or three guys had dumped in her.  For all I know that might have happened.  Fran was a woman possessed in bed; apparently being unfaithful agreed with her.  Our sex life had gone from three or four times a week to two and three times a day.  I loved it, but I didn't like it if you know what I mean.  I loved the sex, and it was kind of kinky getting sloppy seconds every day, but the knowledge that the woman I loved was being untrue to me was tearing my guts out.

 Wednesday, Thursday, and Friday were more of the same and I wondered what kind of an excuse Fran would come up with to sneak away for a quickie on Saturday.  Not that it mattered because Saturday was when I was going to pull the plug on her.

After breakfast on Saturday I went downstairs and got a couple of suitcases and carried them up to the bedroom.  Fran asked me what I was doing and I told her that I was leaving her.  She got a strickened look on her face and asked me why.  I told her I couldn't live with women I couldn't trust so I was leaving.

 "What do you mean you can't trust me?  What have I ever done to you that you can say that?"

 Then I told her about overhearing her conversation with Cindy, that I'd heard her say she wanted to fuck another man and that in fact she would love to.  I told her I had heard them discuss the K-Y plan and I told her that I had gone along with it because I had to know if she would be unfaithful to me on Monday. 

"When I came home Monday there was no doubt that you had been with another man, and the same can be said for every other day this week."

 "You think that I have been screwing other men?"

 I nodded my head yes, "Every day this week I've come home to find you full of some one else's cum, so yes, I think you have been fucking other men." 

Fran was very quiet for several seconds and then she said, "Yes, I've wanted to have sex with another man and, yes, I did tell Cindy that I would love to do it, but I love you.  I love you so much that I could never go to bed with another man unless I had your blessing.  I did the K-Y thing to do what Cindy suggested - to see how you would behave if you thought I'd been with someone else.  And you acted just as she said you would, you were a sex maniac that night and all the next day.  I loved the way you were so I made sure on Monday that you came home to the same sensation. 

I guess I kind of hoped that you would bring up the subject of other men and we could talk about it and maybe I could explain why I wanted to try another man.  But you never gave me an opening, all I knew is that you were really getting off on thinking that you were getting me after some one else.  The rest of the week I kept you thinking that, but I never cheated on you, I just couldn't.  I did go over to Cindy's on Monday and I did do some heavy necking with one of the guys and I let myself get felt up pretty good.  He even managed to get a couple of fingers in my pussy and I actually had my hand on his cock when I came to my senses and ran home.  I could not cheat on you.  I love you too damn much.  But even though I couldn't actually do it I thought you wanted it so I made you think that I did."

 She walked over to the wastebasket by the bedside table, picked it up and dumped it on the bed.  "There are my other lovers," she said as I looked at the nine empty K-Y lotion bottles.

We had a long talk after that.  She told me that she had always been curious about what another man might be like since I was the only man who had ever made love to her.  I admitted that I kind of got off thinking that I was following some one into her and that it was only the trust thing that had upset me.  She said that's why she had hoped that the K-Y trick might make me want to talk about the subject:

 "If you know and say yes, it's not cheating is it?"

Monday at work pretty much sucked since the only thing I could think about was what Fran was doing and what I would find when I got home that night.  Fran was going to sample her first strange cock today and I was going to go home to genuine sloppy seconds.  I couldn't wait.
