The story so far:
This is a fantasy I have about my wife, Amy. In the first part I introduced her to Mike, a guy I met online and had talked to about fucking my wife, though she didn't know that. I had hoped they would hit it off and after quite a few drinks they fucked (which I watched). She ended up spending most of the weekend with him and now, it seemed, they were lovers.
My dream come true, so to speak.
A while later he invited her to stay with him for a long weekend at his apartment in another city. Mike took her out and they fucked all weekend. At the same time she began doing things for him: not wearing underwear, shaving her pussy, and generally being sluttier than she had ever before. It was great for me, because I got to live out my fantasy and her sex drive had increased.
We were having a lot more sex these days, though Amy liked to tease me more now. Not letting me cum for a few days before finally relieving me. We both love oral sex, which she wanted a lot more these days, and our hands were always all over each other. Often she would have me go down on her, then after her orgasm she would roll over or get up and leave, before I could even get ready to fuck her. For a guy with a very high sex drive, this role was driving me crazy. And she knew it, in fact we talked about it openly. I knew she was teasing me and she knew I was loving the feeling of blue balls.
The day after Amy returned from her trip to Mike's house she told me that she would be going back on the pill after stopping almost a decade ago. She said mainly it was because she was having a lot of sex now and it would be easier for her than condoms (which I had been using for the last 10 years with her). I agreed that we didn't want to have any "accidents" and so going on the pill was a good idea. She smiled and kissed me.
It was so hot knowing my wife was another man's lover.
Amy and I were still very close and intimate. Anyone who didn't know about our sex lives would think nothing had changed. We still held hands and still kissed and touched a lot. I knew Amy was keeping in touch with Mike, though she never told me. Sometimes I checked her phone and looked through her messages. They seemed to "sext" each other a lot, and I assumed there were emails as well.
Then one day she came to me and said that Mike was coming down again... but instead of a hotel, she wanted him to stay with us. I thought that was a great idea and instantly volunteered to move into the spare room while he was here. My mind was racing with the thought of essentially submitting to another man in my own house.
It was a little over a week before he was going to arrive but Amy had the house spotless, she also brought in supplies to last us a month including a huge amount of alcohol. When I asked why so much, she replied that Mike was staying for a week and she wasn't sure how often they'd go out.
We didn't have sex at all that week, though Amy teased me and kept me hot. One night she told me not to sleep in the spare room (to get used to it). I heard her orgasming through the shared wall. This was driving me wild.

The day finally arrived and Mike showed up at our house. My wife almost ran down to meet him and kissed him right there on the doorstep. I hadn't seen him since he had fucked Amy that first night they met; I forgot how similar we were in size (my brain had transformed him into a 6'6" Adonis). They kept kissing until Amy finally broke it off and led Mike quickly into our bedroom. He winked at me as they walked past.
I brought Mike's bags in and closed the front door. They didn't bother to shut the bedroom door because they had nothing to hide. I watched them roll around on the bed shedding clothes and making impatient noises. Amy finally ended up naked on top of Mike, her back to the door. She was sitting up holding her tits, and then she bent forward, kissed Mike slowly and reached back.
My wife grabbed his thick cock (still larger than mine) and slid it into her wet shaved pussy (something she had done for Mike). It was a sight to behold as she rubbed the head over her slippery pussy lips before pushing it inside her with a small gasp. She sat back up and impaled herself on his unprotected cock, shivering with delight as she did. She sat there for a bit just slightly wiggling her hips, enjoying the thickness and depth of cock that she hadn't had for a while now.
Mike grabbed her hips and she began moving for him. Grinding her pussy back and forth on his huge cock. She began grunting a little, she always made those noises when she was really turned on. Only a minute into fucking him and, even from where I stood, it was clear she was about to cum. Mike stopped her and grabbed her legs.
He pushed her knees up so she was squatting on his cock. That must've been a great view for him, with her pink clit pointing right at him. She began to move up and down on his shaft, grunting as she reached the bottom and his cock was completely inside her. I saw mike move his hand forward and start to rub my wife's clit as she rode him slow. She moaned as he touched her, already sounding like she was about to cum again.
I heard Mike say "fuck me like you did last time."
Amy nodded and began to move up and down hard on his cock. Really bouncing on it, slamming it into her cunt, each time with a very loud yell. Faster and faster she rode his cock until I saw him reach forward and grab her ass as he came. Groaning and pushing himself up inside her, pumping his cum into my wife's pussy. She moaned and sighed and lay on top of him.
They lay for a while enjoying each other's warmth. My hard on was rock solid. Then I saw Mike look up and see me. He whispered something to Amy, and she looked over. I was quite embarrassed but stayed where I was, looking sheepish. Mike whispered again and Amy smiled and said "I'd like that." She sat up again, Mike's softening cock still inside her, and called me over.
