This is the story of another of my wife's infidelities.
KK has never confessed to any of this, but I was for the most part aware of it on the basis of suspicion during these events.
Through an unexpected route, I've confirmed the affair, or more appropriately multiple infidelities.
This took place when we were in the back half of our 30's, when KK was in graduate school.
KK is a commercial photographer, and had decided to return to school to complete an MFA program at a local university.
KK arranged with the program chair a modified schedule that still allowed her to work, and execute the program's curriculum, at the expense of one summer session and an extra semester.
The program required her to attend some lectures, labs, and session work on weekends.
The schedule was demanding, and we both had to make work-life balance adjustments to deal with the realities of jobs, family, and her MFA program needs.
Most of KK's fellow graduate student classmates were anywhere from 7 - 10 years her junior.
She'd already been working for about ten years in the business, on an accelerated career track.
I ended up many evenings and weekends over a three year period dealing with childcare and other issues, so that my wife could attend school.
We'd long ago agreed to support each other's educational and career aspirations, and I intended to meet my obligation, given KK had supported me during my graduate work, even when it coupled to the near marital disaster that became entwined.
By KK's second semester, we had evolved to a workable routine, with KK attending some weeknight classes, and classes three weekends out of every month.
I noticed that she was unusually horny, and sexual, not only on the free weekend, but other times as well.
During that period we were having some of the best sex of our lives, even though we were both tired and stressed from jobs, kids, and all that was going on.
I was grateful, because my wife was satisfying all of my urges, and the frequent, regular sex was good for me.
In that time frame, my wife had developed a particular fondness for a handful of things that at the time were "new," outside the norm for her - one act she loved was having me perform oral sex on her after I had cum inside her.
A few times I'd gone down on her after cumming, but those were mostly accidental events.
Her deliberate demand for it was new, and she seemed to relish the act, almost to the point of obsession.
The first time it happened, I had been fucking her vigorously, and blew my load in her before she had an orgasm.
She said something to the effect, "I'm not done with you," pushed my head down between her legs, clamped her thighs against my ears, and essentially forced me to lick her pussy to an orgasm, while my jizz leaked from her juicy pussy into my mouth.
The cream-pie, cum-eating thing became part of very nearly every encounter I had with KK, almost ritualized.
Another relatively novel thing was frequent anal sex - KK had always allowed me the pleasure of her ass, even from the time we were dating, but it was relatively infrequent.
Anal had become a regular part of our sex life - including dildos, my fingers, and my cock penetrating her tight little bung hole.
KK had really developed an enjoyment of having a big dildo in her pussy or her ass, along with my cock in whichever hole was available, being DP'd, with dirty talk, fantasizing about having two cocks filling her up.
More than a few times during those simulated DP sessions, KK went wild, writhing, moaning, vocalizing.
She would cry out, "Fuck my ass baby! Fuck my ass!" - this while my cock was in her pussy.
A couple of times she even called out a name, "Wes" is one I remember.
Later when I'd ask her about whoever's name she'd called out, KK would blow me off.
She'd say, "It was nothing. Just someone I was imagining, made up..."
The third thing she had come to a new found fondness of was mutual masturbation sessions - she would play with her tits, ass and pussy, while watching me stroke my cock, until we orgasmed for one another.
KK's masturbation-exhibition sessions were intensely erotic, uninhibited, borderline off the rails. My wife would totally lose herself in the act.
I can still hear her goading, begging, pleading, "Jack that big cock for me baby! Stroke that fucking rod. Let me see you cum. Cum for me, fucking make it cum for me!"
At the time, I didn't think deeply about where these new interests were coming from, I just enjoyed them along with my wife as new, stimulating aspects to our sex life.
One weekend, on a Saturday while my wife was in class, I was carrying a load of kids laundry down the hall.
At that time, KK's photographic dark room was in a small converted bathroom along that hallway, and the door, which was always closed and locked (due to the chemicals - secured, so the kids wouldn't get into them) was ajar.
I dropped off the laundry, and went back down the hall to see why the door was open.
I looked at the knob and latch, and decided that KK must've been in a hurry, neglecting to close and lock the door on her way to class.
I noticed that there were a bunch of medium-format prints in the racks, and decided to take a look at what she'd been shooting.
I didn't know if it was work related, or for school, but figured it was the latter, because she had a lab and darkroom at her office studio.
I pushed the door closed, then flipped the room's red light on, even though the door had been ajar, as a precaution.
I took a look at the photos on the rack - and was shocked at what I saw.
One image was a couple of young men, I suppose college-age, both nude.
One of them was on his knees, sucking the other young man's cock.
Another photo was of a pile of intertwined male, and female bodies, engaged in what was obviously an orgy.
There was a third photo of a blindfolded male, standing, his wrists bound, arms over his head, legs spread, his cock erect, curving up, jutting out like a horn.
The fourth photo in the rack captured a carefully posed image of a young man holding his erect cock, near the lips of a young woman seated on an upholstered stool - a string of saliva and cum extended from the tip of his cock to the tip of her tongue.
I stood there, my cock getting hard, looking at the four images, trying to sort out what they were for, when, and where they were acquired, and what it all meant.
KK wasn't known for shooting this kind of stuff - it was on the edge, bordering art, fetish photography and pure porn.
I heard a bunch of racket, and I came around from my stunned state - it was the kids coming in through the back door of the house.
I turned off the light, exited, then closed and locked the darkroom door.
The whole afternoon, I thought about the photos, KK, and wondered what was going on.
