My wife's name is Katie. Katie's a substantial name I think. Clean sounding, conservative, old-fashioned, and not flashy. I guess that pretty much describes my Katie. By substantial, I don't mean fat or anything like that. Katie's very pretty, she could be beautiful if she'd use make-up, but soap and water is good enough for her. Her body's spectacular. 5'4" tall and 34C-24-34, with beautiful jet-black hair. Of course, I'm about the only person who has ever see her naked and she wears clothing that tends to hide her figure. Conservative, substantial clothing.

Katie and I got married right after she graduated from college with her teaching degree. She's 29 now and I'm 35. Katie's always been a good lover. Not wild or anything, but very loving and willing. She's no prude but she's no "hot wife" either. Maybe three times in our marriage Katie has gotten really wild in bed. Thinking back on it now the same ingredients were present each time; First of all it was the right time in her cycle. Katie's always a little bit hotter when she's ovulating. The other ingredients are that she'd been drinking, that gets her motor running, and something else has been going, on like a sexy movie or something. On those few occasions Katie and I have had sex to remember! That's when I've heard her scream and when she's really lost control.

A few years ago we found out that my sperm count was too low for Katie to conceive. That really hit her hard. For about a month Katie was in terrible shape, crying and feeling bad about herself. I did everything I could, suggested we could adopt a baby, all of that. Finally Katie pulled herself out of it and decided she would really dedicate herself to her students.

I'd like to say that things got back to normal after that, but they really didn't. Katie and I still made love and cuddled, but it wasn't the same. She wasn't really as "into it" as before. I know she still enjoyed it, but we didn't have sex as often as before and I think it made her just a little sad. Sad is not a good emotion during sex. You can see how it wasn't as good as before.

In order to pep things up I started to introduce role-playing and fantasy into our sex life. Katie's always been interested in my feelings so she was happy to go along. One of the fantasies I used involved her with another man while I watched. This particular fantasy developed slowly over a few months until the really defining night.

We'd had a couple of drinks and were in bed, just kinda messing with each other. I was about _ hard and Katie was starting to get moist between the legs. I asked her what the "mystery man" would look like.

After thinking for a minute she said, "Like Tom Selleck. Not like Tom Selleck on Friends, more as he was on Magnum P.I. You know, younger with the mustache."

"Really," I said getting a full hard-on. "Tell me what you'd do with your Tom Selleck 'mystery man.'"

She put her head back and started to describe what she and her "mystery man" were doing. She described him kissing her and squeezing her boobs. She told me how he's touch her everywhere and how turned on she'd be. She was really getting into it.

When she started to describe how he'd fuck her she looked up at me and then down to my now throbbing prick.

"You like this don't you?" she asked as she reached out her hand and very gently touched my hard-on. "You like the idea of my mystery man: fucking me while you watch."

Her touch and her asking me if watching her turned me on was enough. I came, hard. Katie looked down at my cock in surprise as I pumped my cum onto her hand and wrist.

"Oh yes," was all she said. She smiled at me.

When I finished she rolled onto her back again and spread her legs. For the first time in our marriage, I watched as my wife touched herself. She has such a beautiful cunt. Her hair is jet-black and her pussy lips are pink. She started to run both of her hands over her pussy, pulling her labia apart and showing me the exquisite pink inside. With her eyes closed she worked her fingers, covered in my cum, into her cunt. Covering it with her moisture mixed with mine.

"Oh god. It would feel so good to have him play with my cunt." I'd never heard her use the word "cunt" before. I watched with my eyes opened wide as she continued to masturbate before me.

"You're watching as he takes me. He fucks me, hard. Pounding his big cock into my cunt," she almost screamed the last as she came on her thrusting hand.

I was fully hard again and wanted to fuck her. Oh how I wanted to fuck my wife at that moment. It was as if the mystery man was there in the room with us.

As I eased my aching cock into her she opened her eyes and looked at me. Confused a little at first and then aware.

"It was almost like he was here wasn't it? Fucking me as you watched. Oh god it was soooo goooood!!!!" and like that, we were both cumming. I'm not sure, in her mind, she was really fucking me.

It was a neighborhood party a month or so later were our lives changed forever. It was a toga party; some idiot's idea of a return to the 70's.

Katie and her friends made togas out of bed sheets. Real nice too. I'd have just wrapped a sheet around myself and gone, but the girls did everything right.

Katie's was a little short, shorter than she usually likes things and, of course, exposed one shoulder. Now that bare shoulder became something of a problem because, as it turned out, Katie didn't have any bras without straps. Don't ask me I don't know anything about bras. So Katie decided she'd go braless, just this once. When we walked out of the house, she was wearing her bed-sheet toga, panties, and shoes. That's it. About as bare as Katie gets.

The party was great fun. I have to hand it to them, the togas were a great idea. The liquor flowed and all the guys were there and after a while I lost track of Katie.

Sometime later Katie grabbed me by the arm and pulled me away from the guys by the bar.

"He's here!!" she whispered urgently.

"Who's here?" I'd had a few and, obviously, so had Katie.

"The 'mystery man!'" she said pointing with her head to her right.

I looked and, sure enough, a guy that looked like a young Tom Selleck, mustache and all, just a little shorter maybe. He was talking to a couple of other people.

"Well shit, he does look like your guy. Have you talked to him?"

"No. NO. ARE YOU CRAZY?" she was whispering pretty loud. My estimate of how much she'd had to drink went up.

"Well, why not? Go ahead say 'hi.' I mean, what the hell, he probably won't fuck you on the dance floor."

She looked at me kinda funny and then over at the guy. "Well OK. I'll talk to him anyway," and with a small punch to my arm, she wondered off.

I watched her out of the corner of my eye as she took a circular route around the room, eventually ending up in the group talking to the guy. I lost track of her after that for a while. When I saw her again she introduced me to her friend.

"This is my husband. You'll never guess this guy's name, honey. Tom. Isn't that incredible?" she said to me. Katie was really enjoying this and was more than a bit drunk.

Later I caught sight of her again. This time she and Tom were dancing so a slow song. The lights had been turned down and they were way in the back of the dance floor. He was holding her close and she had her head resting on his chest. The weren't moving really, just grinding against each other. Even though I'd drank quite a bit by then I got a major hard-on watching them.

It was when the song ended and he kissed her that I almost came in my toga. It was a real passionate kiss and she hugged him tight. I watched fascinated as Tom slipped one hand under the top of the toga and onto Katie's breast. They continued to kiss for a moment while he caressed her and, as the kiss ended, Katie took his wrist and pulled his hand out of her costume. She was smiling up at him though, she certainly wasn't angry.

I tried to keep an eye on them after that but I lost them in the crowd. Later I went looking for them. No, it wasn't like the stories, I didn't find them going at it hot and heavy. In fact, Katie found me.

She was breathless and just a little mussed up. Her face was flushed and she dragged me upstairs and into one of the bedrooms of the large house where the party was being held. As soon as we got in the room, she threw herself at me kissing me passionately and digging under my toga for my cock.

"I really need you to fuck me right now. I'm so damn horny I can't stand it," she was panting with need.

She was hot. I reached under her toga to find her panties dripping wet. It was like they'd just come out of the washing machine. She was soaked through. With her help I had her panties off in a minute and held them dripping in my hand. I slipped my hand back under her toga to find her pussy slopping wet. Her labia were completely open and her clit was a hard nub under my fingers. Just touching her pussy caused her to hump back and forth on my hand and sigh as if she was already being fucked.
