I could do as she asked. I carefully held her inner lips open with one hand and while I continued to hold his cock steady with the other. Looking into my eyes, she lowered her body. Joy she could not suppress lit her face as she again made herself one body with our friend, her former lover, taking him easily all the way in on the first stroke, thereby again making him her fucking lover - a lover who would enjoy her charms, soil them, and then if we followed the plot, watch me clean her up for him to soil again.
Besides the joy in her eyes, I also saw the infidelity darken her soul. As he entered her she mentally played back their good times - there were few, but they were very good for her. She rose again and exposed his shaft, which had been dry. Now it was wet and slick with juices. He was the first lover to bring her joy from the start, and the first she wanted more of each time she had him. Part of her wanted those youthful good times back. We had talked about it, part of her knew time had enhanced her memory of the good times. She moved down, taking his cock inside again. Part of her did not believe that and there was some greed in how she wanted his love to make her young again, to transport her back in time. I saw her struggle, but I was confident she would make the right decision.
Then she went off script. The improvisation is one that I recognized from another story.
After just two strokes she stopped moving. She had lifted herself carefully until just the head of his cock was inside her body, leaving his wet shaft was exposed. My thumb and finger were still wrapped around the base of his cock. That was when she asked me to stroke Jace's cock up and down while she held still, basically to masturbate him into her pussy. She was really working me into the act, but then, that was kind of what we had in mind with this. Stroking Jace's cock might be a little out-of-bounds in terms of what I told him the first day, because the act was pretty queer and was something I never really did to him with Cindy. But on the other hand, he had told me about those times when he was younger, in summer camp. He and his high school-aged buddies played games while exploring each other's bodies, discovering things about themselves. They did not limit themselves to fingers.
I started to stroke his cock, and I guess I did it well, stroking his slick shaft while she held just his cockhead inside her body. She pulsed her pussy muscles in synch with my movements. Jace said "Oh yeah, fuck me that is good!" in response to our combined attentions.
As requested, all this time Jace was playing with Deni's tits and nipples, and doing so very effectively, the way he did when they dated during those fall weeks freshman year. Maybe it was not as smoothly effective as the moves I developed over a decade of practice, but it was not to shabby either. Deni was quite enjoying the variety of his touch as she tripped down her "Naked Memories" lane.
As for Jace, there was sometimes a moan or a groan, but basically he was listening and feeling, not talking. Still, his hands were a pretty good indication of how the day was turning out for him. He really liked this part.
After a few strokes she departed the script yet again when she asked me a question from the other story she had patched in play. "Would you get a bigger kick out of this if I let you do the faggot thing and stroke him off so he spews directly into your mouth? Or is it more of a charge to see him pleasuring himself and your wife with a good fucking, having him squirting cum into the pussy where your babies entered the world, and then have him watch you eat it out of me after? Either way, you get a mouthful to swallow."
That question was intended to grab both of us guys by the balls.
I know Jace got very close to the edge, I had to loosen my grip to keep him from popping. Even though I had read the story many times it also grabbed my balls, cranking them up. It was also a pretty smart question, since it opened the door with how, in the future, our threesome was implicitly going to include activities that were not strictly heterosexual. That was an issue that would weigh on Jace's mind before the next trip. With her question, my wife put a very positive spin on the issue, made it a joint source of positive interest for all three of us, but especially for Jace.
After a few more strokes she stared into my eyes, wordlessly telling me she was back on the original script and was ready to start the climax of this scene. I stopped stroking and held Jace at the base of his cock. She lowered herself slowly, enjoying every inch as his shaft penetrated into her body. I kept my fingers as they were while I sat mesmerized, so I both felt and saw Jace's cock disappear into my wife's pussy right in front of me. At the last minute I withdrew the hand holding her open, deliberately brushing her clit as I drew it away. I touched her just right, as she settled her body gave the little shudder of a near-climax from the contact. As for my other hand, thumb and forefinger were still wrapped around Jace's cock and therefore wound up sandwiched tightly between my wife's pussy lips and her lover. Except for the width of my finger, Jace's cock was entirely enclosed in my woman's sex.
Instead of positing up and down as she usually did when we rode the chair, Deni began to move forwards and backwards plus side to side, rotated her pelvis around in a slow circle. She was 'stirring her pot' with Jace's cock, and it had to feel pretty good to him. Plus she was literally rubbing my hand into her joining like some sort of mutual masturbation toy, getting the near-clit contact that worked so well for her. She knew that was the message she was sending to me, and I have to admit, it was tripping us all out.
Deni said later that she would have rather turned around, to get some kissing on Jace, but things were going too fast; she knew Jace was really close to a climax, unlike us he had been without sex for a week, and had even been abstaining from self-service - mostly - to build reserves in anticipation of putting the most creamy fun into this 16-hour visit. Deni was wound up enough by the little detours that she just might beat him to the climax. Things could go longer some other time.
She told me later that she was intensely aware how both of us were sexual partners for her body, men who desired her pleasure and were climbing over some significant emotional barriers to reach that goal.
She was still his slut right now, despite our open line of communication I knew that she was 80% focused on Jace, where he was inside of her, almost ready to cum. She started the path to final countdown by finally moving strictly up and down. It was a clear signal to both of us guys. I shifted my hand a little, just enough so she could use the knuckle of my thumb to hammer her lovely little pleasure button with each stroke. Now that they were in the home stretch Deni and Jace were not subtle about getting their fucking pleasure, in fact it was only slightly short of rutting.
I watched breathlessly as my old friend got ridden slowly to orgasm by my unfaithful woman. I was literally holding on to him and pleasing her as her attention faded from me.
She crossed over in terms of her attention when she reached back with both arms to pull his head and body to her. The way she 'needed' the contact, the embrace, said there was no longer room for me in her focus.
Harder and faster, they got louder until Deni started making this moaning-groaning noise and Jace was grunting with each stroke she made on his cock. His arms wrapped tightly around her. Deni went up and down again and again, like a machine of flesh, building and building the tension between them like a great spring until suddenly there was his release. It was the moment when suddenly he had to move, driving himself up to meet her downstroke. At the same time my hand, wrapped around the base of his cock, felt that first powerful stroke, and the mighty surge when I felt him cum. His balls moved. His cock, wrapped in my grip, convulsed and expanded so I felt the first pulse of his semen shoot up his shaft into my wife's pussy. When I saw his shaft exposed on her next upstroke, it was coated with his thick white cum instead of her clear lubricating juices. I watched his balls pulse as they pumped his seed again, plus I felt each pulse with my hand as his cum was filling her.
