The first detailed confession of cheating my wife ever provided was one of the more arousing, erotic experiences I've had.
The first time I experienced hands-free ejaculation, outside of a pubescent wet dream was during this confession about her experiences with an ex, "Monty." The confession took place about five years before our first hot wife experience.
Monty came into the picture during our college years. I was casually acquainted with him, and mostly disliked him - classic rich college kid, riding on family money, and buying his way into, and out of everything. He was a frat boy too, another thing I have general disdain for. He was in my then finance's circle of friends.
Long story short, my then fiancΓ©, and now wife, KK cheated on me with Monty, and eventually broke off our engagement to fuck/date him, among other things.
Later in life, decades after we were married, and after I had engaged in numerous extra-marital affairs, I got caught. We decided not to end our marriage, but instead entered into therapy. One outcome of that was counseling to try not withholding things, or keeping secrets.
A few months into that therapy and counseling, our relationship had started healing, and recovered to the point that KK and I were having frequent sex again.
Our sex life, and in general lovemaking had improved, and intensified for a variety of reasons. One weekend morning, on a Saturday, we were lounging in bed, making out, engaged in hot pillow talk and fantasy play. I was narrating thoughts of my wife fucking strangers into her ear while fingering her.
She was incredibly aroused, wet, and had two intense orgasms in fairly short succession as I played out fantasies of her engaging in hot, dirty sex with strange men. In a pause, she rolled toward me, and pushed me onto my back. My cock was rock hard, and I really wanted to fuck my wife. I remember that my cock was twitching, pulsing, and my balls ached with desire.
Out of the blue, KK blurted out, "Do you remember Monty?" At first I drew a blank, and didn't respond. KK said, "You know, Monty, that boy in college?"
I finally responded, "Yeah... Monty."
KK said, "I have a confession. I fucked Monty. I fucked him while we were together. I cheated on you."
I felt a combined sensation, like my heart might stop; light-headed, hot, short of breath, and the simultaneous intensity of arousal and lust, incongruent with hearing my wife tell me that she'd cheated on me. My cock was throbbing, and my balls ached.
Kneeling beside me, KK went on, with her hand on my thigh, "Monty had such a nice cock... so big and so pretty... I used to love sucking Monty's big cock, and playing with him. Monty had such a beautiful cock-head baby - it was big and fat, like a big sweet plum..."
That made my cock even harder, and I tried to subtly move her hand onto my cock by rolling my leg. It didn't work, and she just kept talking.
"You probably don't remember, but I do... we had a date, you and I for some big deal you had cooked up. But Monty had been hitting on me a lot, and it was fun to flirt with him. He wanted me to hang out with him and his roommate to smoke out and drink. I didn't really want to go on another boring date with you, so I lied, and told you daddy was in town, and wanted me to have dinner with him - so I broke our date. I remember you got really, really mad... but I didn't care..."
I did remember. I'd made that date with my fiancΓ© to give her what I thought was good news, a "big deal" in the sense that I'd gotten a paid intern job, that would cover the rest of my undergraduate program, and let us get married earlier than we'd planned. Now I was finding out KK'd lied to me, in order to cheat on me.
KK continued, "That very first time I fucked him was so hot! Is it so dirty and wrong to fuck on the first date? It wasn't really a date though, it was just hanging out."
I thought it odd that she still seemed to try and rationalize it, even decades later.
My wife kept talking, "I fucked him in front of his roommate. Did you know that? His name was Steve. I let him watch me fuck Monty. We were in their apartment, watching a porno and smoking dope. I got so horny, and I just decided to do what the girl on the video was doing."
