First, a little background: my wife is fairly short (4’11”), maybe 5 lbs overweight, has a beautiful face, and smallish tits (at least at the time this happened) with large conical nipples. Cheryl was very conservative and shy about sex and while she enjoyed it, didn’t feel comfortable talking about it.

The first time we met, we were in our late teens and dating other people. She was with my best friend Mike, and I was with my girlfriend in my car out in the remote Kansas countryside one night. We were all drinking cheap wine and making out. At one point Cheryl starting moaning in the back seat, accompanied by the wet, squishy sounds of some sort of penetration.

I managed to surreptitiously adjust my rear view mirror with one free hand while kissing my girl, and what I saw almost made me pop: Mike was twisted in the rear seat with his back to me, making out with Cheryl. His pants were around his knees and Cheryl’s right hand was slowing pumping his rigid uncircumcised cock – I remember in the light it looked purple.

Cheryl’s skirt was pulled up and her panties, if she had been wearing any, were nowhere to be seen. Her legs were splayed wide with her left foot resting partly out the window, and her right leg propped over Mike’s left. I will never forget the sight of my friend’s two or three fingers slowly plunging in and out of her fuzzy vagina, her swollen lips glistening with moisture, and the sucking sound produced every time Mike’s fingers pulled out, then the squishing sound when he plunged them deeply back into her.

The night concluded with me fingering my date to an orgasm but (unfortunately) not getting off myself, and Cheryl sucking Mike off after reaching a thrashing climax thanks to his magic fingers.

Several years later Cheryl and I got together, lived together for a period, then got married. After drinking, smoking, and watching porn at another couple’s house one Friday night we were driving home. One of scenes in the porn tape featured a woman getting fucked in the back seat by her boss while her boyfriend was forced to drive. The scene brought back horny memories of watching the woman who ended up being my wife being pleasured.

As we had sex that night, I told her how exciting it was watching her have sex with Mike years ago, and I could tell it turned her on. At one point as we were fucking I asked my wife what it felt like to fuck Mike’s big dick, and as she haltingly described the sensations, she started fucking me so hard the bed was banging against the wall. She actually screamed, then tightened into spasms of orgasm that went on forever.

From that night on, when we were having sex I’d often tell her to imagine that I was Mike (or another man) because it not only turned her on incredibly, but for some weird reason it turned me on, too. I started increasingly fantasizing about her fucking another man, but as much as I was desiring for it to happen, when she wasn’t having sex, Cheryl was too shy to actually ever do it.

Fast forward about 12 years: One night at her employer’s company pool party and after a couple drinks, my wife’s coworker and good friend talked her into taking an ‘ecstasy’ pill, and gave me one also. The friend said it was harmless stuff, and would just make us feel “really good.”

To make a long story short, approximately one hour and two margaritas later, Cheryl pulled me aside and informed me we where leaving – right now. As I started driving, she suddenly blurted out that she had never felt so horny in her life, and to accentuate the point, she pulled my hand under her skirt and against her hot, sopping wet panties.

I realized the pill (and Cheryl’s overt sexuality) was having the same effect on me, and I pulled over in the first parking lot I came to, which happened to be next to a small adult bookstore. As I fingered my wife and she stroked my cock through my shorts, I suggested we do something we as a couple had never done in our lives – go into the adult bookstore, maybe pickup some sex toys and a porn tape, so we could go home and have the time of our lives. To my dismay, she was so horny she actually agreed.

We were surprised to see some other couples among the men, which put Cheryl at least somewhat at ease. After looking at some toys, we ducked into one of the video booths at the back. The whole thing seemed so nasty, and after paying for the video, we started making out like over-sexed teenagers.

Just as I was sliding my hand up her thigh, she jumped back and pointed to the dark wall beside us. I thought for a second the erect cock bobbing through a hole in the wall was a sex toy, but it was soon apparent it was not. Cheryl looked at me and mouthed “oh my God!…” and we both just sat there, not knowing quite what to think. Suddenly I was struck by the realization that my horny wife was inches from some stranger’s penis, and I wanted nothing more than to see her touch it.

I slipped my fingers past the elastic of her panties and into what felt like hot pudding. She pulled my fingers out, stood up, and pulled off her skirt, than panties. I motioned to the guy’s cock, and she mouthed “no.” I grabbed her hips and pulled her to me, and buried my face into her steaming crotch. I noticed with disappointment that the penis disappeared.

In no time Cheryl was moaning and her legs were quivering. I became aware of noise on the other side of the wall and suddenly another penis slid through, this one black and fat. I made my move. I reached up and pulled my wife’s face to mine and shared her juices in a sloppy kiss while inching her backwards toward the bobbing cock. She leaned and whispered into my ear, “Are you sure?” My response was to deeply kiss her as I leaned forward, pushing her against the strange cock. She gasped as it slid between her thighs, poking through like a black cucumber. I whispered in her ear “go ahead,” and she quietly reached back and guided the cock into her.

My conservative, shy, quiet wife grunted and ground her hips as she slowly worked every inch of the black stranger’s horse cock into her. Her legs were shaking as she leaned forward, then slowly pushed her ass back against the wall. I couldn’t believe what I was seeing, looking through my wife’s quivering thighs and seeing some other guy’s gooey, glistening, fat penis sliding in and out of her steaming snatch.

The sex act itself lasted maybe all of two minutes. Just as I was trying to place my cock in her mouth, Cheryl started slamming her ass against the wall, moaning “fuck me fuck me fuck me fuck me fuck me.” She proceeded to convulse and moan for what seemed like minutes as her new boyfriend filled her with wave after wave of seed that dripped from her in big globs when he pulled out, and left a gooey memento of the evening on her leather seat during the quiet ride home.

While Cheryl has since fucked other friends and strangers, nothing ever quite matched the intensity of that evening. She refers to it simply as “the big bang.”

This story is 100% true.
